Product Description of High-performance pipeline ball valve-reduced bore:
High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.
Design Features of High-performance pipeline ball valve-reduced bore:
Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength, high perfect sealing, maintenance-free, long life and so on. The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology, selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology. At the same time, with the years of ball valve design and manufacturing experience, the use of advanced processing and manufacturing equipment and production and processing technology, through the first-class inspection and testing equipment and instruments, perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves. This series of valve has the performance of a high strength, defect-free forging body, excellent sealing performance, even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage, after frequent switching action to realize a safe usage in the transportation of oil, natural gas, coal gas, and other special medium transportation pipeline.
The special structure of valve seat seal of High-performance pipeline ball valve-reduced bore:
Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(Ⅰ)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(Ⅱ)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile,due to ring A in the medium resulted in elastic deformation under pressure so that the sealing ring B is also closely fit the surface of ball for the formation of the second stage seal.When the system medium pressure increasing,it will have an enormous pressure in the valve seat ring A and ring B,so that the two seals have a greater elastic deformation,and then the metal valve seat ring surface and the ball surface sealing together to form a third level of metal to metal seal.
(Ⅲ)The assisted valve seat sealing equipment
Based on the actual service condition,medium requirement,sealing requirement,etc.,the assisted valve sealing equipment will be considered to be necessary or not.The assisted valve sealing equipment is a one-way valve installed outside of valve body that can prevent medium leakage and can inject sealing grease into valve body by external force.When the assisted valve seat sealing equipment is required,valve seat ring shall be design and processed with injection grove and hole to connect the assisted valve seat sealing equipments.Such equipment can prevent the medium by the sealing of injection of rease.Refer to Figure5 for reference.
Multi-level structure of stem sealing
Figure6 shows the stem multi-level sealing by adopting"O"ring,flexible graphite and grease injection;"O"ring achieves the first level stem sealing;Replaceable flexible graphite realizes the second level sealing by the compression of packing sleeve and packing flange;And the third evel sealing is realized by installing assisted sealing injection valve to the packing box,and by designing with the injection groove and hole to connect with the stem injection valve,which can inject grease.
Unique and safe seat structures of High-performance pipeline ball valve-reduced bore:
Ball valve fireproof design is implementation of the API607,API6FA standards.According to service conditions and user requirements,ball valve can be designed as a fireproof structure.
(Ⅰ)Fireproof structure of seat
As shown in figure7,there is composite fireproof ring,which are combined with graphite and stainless steel wire in the seat.Once the soft ring is burnt out in case of a fire,the fireproof ring and seat ring will form a piston structure through the spring to load the valve body.That will push and closely contact the metal seal surface of the seat ring to the body surface,So as to prevent a lot of medium from leaking from the burnt place of the seat ring,and prevent the fire from expending.
(Ⅱ)Fireproof structure(body and bonnet)
The seal gasket for bolt connecting valve body and valve bonnet,are used fireproof stainless steel wire and flexible graphite gaskets.Gasket compression load through the bolts and ultimately,ensure the valve body and valve cover between the metal to metal contact,so that the valve can with stand more high load,but also improve the fire safety of the valve.But for the full welded ball valve,the valve body and cover is welded structure,that fundamentally eliminate the possibillity of leakage of the valve housing.Even in the case of fire damage,there will be no leak.
(Ⅲ)Fireproof structure(body/packing and stem)
The body and packing connection gasket adopts fireproof stainless steel wire and flexible graphite gaskets.The stem packing adopts flexible graphite to ensure no leakage in case of fire.

- Q: Hello all,I have a1990,BMW 525i.I bought this car from another guy about year back and drive around 13000 kms.1.Do i need to adjust the valves(both inlet and outlet).2What is the importance of valve adjustment3Does it affect the mileage4.As a regular maintenance for how many kms can i drive without valve adjustmentExpecting your valuable replies.
- if it needs to be done DO IT. valve clearance is very imporant. the sound of a valve hittin a piston isnt good. especially if you bend a valve which you will. valve adjustment isnt hard if you kno bout cars a little bit.
- Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.
- Sounds good to me,
- Q: In December I got a new John Packers Bb Cornet and it was fine to start with. But recently the valves have been sticking, especially the 1st and 2nd ones. Even when I put valve oil on them they stick. It's really starting to annoy me, is there any else I can do to prevent this?
- If the valves continue to stick after being oiled, then it's time to clean your horn. Remove all the valves (making sure to keep them in order so you don't put them back in the wrong casings) as well as the slides. Fill a sink with warm (not hot) water with liquid dish soap. Wash all the parts gently with a soft clean cloth. There are special brushes available at music stores for cleaning the insides of slides. After cleaning, pat everything dry, apply fresh grease and oil, and reassemble.
- Q: My new Trek 1000 has a type of valve stem different from the standard (car type) stem on my mountain bike. Do I need an adaptor to fit it to a pump or do I need a whole new pump? Also, have you seen a tire gauge that fits this stem type?

- Q: Just bought car used. It is an 88 Toyota Corolla Fx. It is leaking and loosing a lot of oil. The EGR valve is spraying pretty badly. All hoses are fine. Seems to be in the seal. Is this the possible fix I need to solve these problems? Cleaned and inspected engine for other leaks and found none. Please help. Very poor and highly motivated to fix this car up.
- Hello, The EGR valve will not spray oil, It is an exhaust gas recirculation valve that does not have oil get to it!! Please add more info so we can better answer your question . Thanks for additional info. But I don't think you know what the EGR valve is. Engine oil should not be spraying from the EGR valve ! Maybe you are trying to describe another part? Also, You need to fix the wheel cylinder or caliper before you can bleed the brakes. Maybe you need a mechanic to assist you. Good luck !
- Q: Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
- Q: I been playing the trombone for 6 years, do you think i could learn to play the baritone easily,which baritone is easier,3 valve or 4 valve.
- The forth valve on the baritone is the same as the trigger on a trombone - it lowers the pitch 2 1/2 tones to extend the range downward, to assist in improving intonation, and to solve so tricky fingering problems. You can learn baritone quite easy, if you relate what you know on the trombone to it. Here is a quick lesson on valve playing. Trombone position Baritone valves 1 Open 2 2 3 1 4 1 2 5 2 3 6 1 3 7 1, 2 3 Trigger 4 On high F#, you must play 2 3 On High G, you must play 1 2 Good Luck! It is a great and wonderful instrument to learn, and will help you trombone playing, too!
- Q: I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?
- You aren't getting a lot of power out of a BOV. I don't mean to sound obvious or degrading if you know this but a BOV makes the pissssssss sound you hear when you wined out the turbo. It might help the turbo release some pressure and get some more power that way but besides that not much. You will spend about $250 on a blow-off value and unless you install it it's gonna cost you about $80 per hour to have someone else do it. It is about a 1 and 1/2 hour project so your looking at $370. An air intake on the other hand is what I suggest. To get a brand name it will cost about $250 but you can install that yourself in about 45 mins after figuring out that you have been reading the directions upside down for the last hour. Just kidding... It's a really easy install and it can add anywhere from 10-15hp. By the way, if you don't have a turbo Jetta there is no point to buying a blow off value because it won't do anything. Now that I think about it if you do have a turbo jetta get a DV (Diverter Valve). The nice thing about a diverter valve is that it will prevent you from losing boost which is what gives you most of your power from the turbo.
- Q: My fortuner stalls without warning, but restarts quickly, according to Toyota service center, we need to replace the suction valve, can someone please tell me how a suction valve work
- you need to be more specific. there are 100 things on a car that could be called a suction valve. Right off the top of my head the only valve that could do that is a EGR valve. If it gets stuck open the car will stall, but it will start back up after the valve closes again. The OBD will tell you if the EGR valve is bad, but other than that I can't say.
- Q: i have an 87' monte carlo ss, 64K on 305 w/ cam, headers, roller rockers and springs. ive been seeing blue smoke out of my exhaust ALOT during start up, but it also continues to smoke at idle, i've been told it's a good chance i need my valve seals replaced and was wondering what the general ballpark was assuming there was no other complications in the process of replacing these?
- they're not expensive at all, it's the labor that's going to kill you.
