Design Features of full welded forged steel ball valve
The body of ball valve is full welded,selects high quality forged material,and adopts the advanced forged forming technology to form two semi-spheres which are welded into a whole in the middle of the body.This welding technology differentiates the ball valve form others,and makes the valve more spherically,so the valve structure is more compacter,lighter and stronger.Besides,the middle direct welding realize highly accurate valve body manufacturing,makes fully and completely sealing between the seat and ball.The full welding instead of bolts completely avoids the outside leakage,so ball valve is the ideal product for under-ground,offshore working platform and under-sea equipments.
Adopting fixed plates or trunnion to support the ball
The top and bottom of the ball is supported by upper and lower fixed plates or stem and trunnion,and the ball is accurately placed in the center of the ball valve to achieve complete seals and precise movements.When plate adopted,the force exerted by the medium to the ball is distributed via the plate to the left and right bodies,so that the stem does not bear the blending moment from the medium,but only the torque from the ball rotation during the opening/closing of the valve.The low-friction PTFE Teflon composite bearings installed between the ball axis and fixed plate and between the stem and the trunnion can absorb ball moving action caused by the pressure of the medium.This structure brings stable actions and easy operations for the ball valves,and the required operation torque can be reduced,so smaller actuators can be used,and the cost is cut down.
ball valve seat is floating structure,means the seat can move along the medium direction,so that the seat can fit against the ball all the time.
（Ⅰ）Double piston effect structure seat of full welded forged steel ball valve
Seat design is special double pistons effect structure,it can ensure the seal wherever the medium flows into the ball valve.
（Ⅱ）Seat multistage seal strucute of full welded forged steel ball valve
As following graphic instruction,on seat bearing ring,set two soft sealing rings(A and B)and metal sealing spherical surface which can seal with the ball.Seat ring A is spring loaded,which seals the surface with the ball tightly to the surface to form an initial seat;When there is pressure generated from medium,the piston force is generated to make seal ring A elastically deformed and seal ring B fit the surface of the ball surface due to the piston effect caused by area difference,thus the second seal forms.When the medium pressure is rising.It will generate huge pressure to seal ring A and seal ring B,so the two seals have a greater elastic deformation,then metal seal ball surface compact with ball surface to form the third level of metal to metal seal.
（Ⅲ）Secondary seat seal device of full welded forged steel ball valve
As the above graphic instruction,the secondary seal device(seat grease injection valve)can be chosen according to the actual working condition,medium requirement,seal requirement,etc.Seat ring grease injection valve is a one-way valve,installed on the body,which can prevent the leakage and inject grease under the outside force.When secondary seal is required,there is a grease injecting channel and hole on the seat ring.The grease can form a seal between the seat and the ball,and then stop the leakage.

- Q:I have a honda civic and i took it to get an oil change and they told me that i had an oil leak because my valve cover needed replacing. I did not let them do the work. I called my personal mechanic and he's out of commission for a little while, so he referred me to a friend of his. He said he cleaned all of the built up oil and replaced the valve cover. I noticed yesterday that my car looks like it is leaking oil really bad. I'm wondering, could this be from him washing the old oil that was leaking? My belts seem to be squeaking, like they do when it rains. Any ideas? could this just be excess water that he cleaned it out with?
- if he replaced the valve pan gasket then it could be from where it was leaking at in the first place and he did not clean it off after he got done. if your oil don,t keep going low then you know he got it fixed.
- Q:I was just informed that my 4 year old daughter has been diagnosed with mild mitral valve regurgitation. I have been researching, but only find the information to apply to adults, not children.What general course is taken when dealing with children with this condition and what should I expect? Her pediatrician was treating her symtoms as asthma with breathing treatments, but, I was not comfortable and took her to my family physician, who sent her for the echo, which discovered this.I'm more or less just looking at our options...
- I am not completely familiar with this specific heart problem but my son was born with a CHD (congenital heart disease) called Tetralogy Of Fallot and has had 2 open-heart surgeries. He is only 2 years old but is and has been doing fantastic. I do know a few other parents with children with mitral valve regurgitation and they have had to have mitral valve replacements. When and or if this needs to be done depends on how severe the regurgitation is. You can go a LONG time with regurgitation of any valve. My son actually currently doesn't have ANY Pulmonary valve what so ever right now and hasn't sence his last surgery when he was 9 months. We are not looking for him to have a Pulmonary valve placement until he is about 5-7, so that will be 4-6 years with no Valve at all at 100% complete regurgitation!!!!! Hope fully your daughters isn't too bad and you can wait a few years for her to have a new valve. Children are more likely to reject valves and the sooner it is put in the sooner she will need a new mitral valve replacement. Pretty much anybody that gets a valve replacement will have to keep getting them every 10-20 years of their life depending on what kind of valve you choose, when it is placed and how good they do. Good luck to you and your daughter - heart kids are the strongest!!!!
- Q:I have a problem with standing water that keeps puddling up and never drains under where my valves are located for my sprinklers. What do I do? Should I just put 3/4 drain rock on top? Please help?
- Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
- Q:people tell me i need to install new valves and valve guides
- Maybe you simply need to re-adjust your valves? Or buy a Lancer.
- Q:I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
- Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.
- Q:I'm installing an under-sink water filter. For the saddle valve, how do I drill the 1/8 hole through the iron pipe? What is the easy way to do this? Seems like I will be slipping around a bit. Any tips on this step?
- My under sink filter hooked up the the cold water supply valve with compression nuts. There was no need to use a saddle valve. You could consider getting another type filter or follow mrrosema's instructions.
- Q:recently changed head gasket. could valves tap from the push rods being mixed up? they all seemed to be the same size and i know the other side was exactly the same when put back together but this side is mixed up. could this make the valves go crazy? and i need to replace my water pump because its getting very hot and no coolant moving. and everything is smokin up, took off oil cap and it was steaming. would that have anything to do with making the valves tap?
- there okorder a good site that will help you fix your car and its free and you can ask master tech for help.
- Q:Surly Pilots don't just switch the fuel selector valve of mid flight
- Not to take away from JFK jr's piloting skills but the possibility exists that he failed to check to see if the fuel valve was on in the first place. I do not know how far along in the flight he was, but a typical piston engine plane can get you up and on your way with the fuel that is in the fuel system. Why I know this, my flight instructor while training one of his students died in a forced landing due to engine failure because the fuel valve was not turned on. My flight instructor would allow his students to perform the preflight on there on, of course after many hours of dual training. The plane was a piper four place, it made it to about 400 feet agl before the engine stalled from fuel starvation. The irony of his death was from complications on the operating table from a broken ankle and a blood clot that broke loose. Checking for the on position of the fuel valve is on the check list. During emergency landing procedures, one of the functions is to turn the fuel valve off to reduce the possibily of fire. This doesn't answer the question but is a possibility unless of course he was well into his flight before the accident, in which case he probably moved the fuel valve to the off position following emergency procedures.
- Q:What do I do to make my valves stop ticking? And what makes them tick? its a 94 Acura Integra with a 91 LS motor, 105,000 miles. If I get a new engine head will it stop ticking or the ticking has to do with the block?
- the ticking is common on the ls motor...just adjust your valves....
- Q:What are the names of the main arteries and valves?????????REALLY NEED ANSWERS TODAY!!!!!!!!!!!
- Main arteries: Aorta (oxygenated blood from heart to body), Pulmonary Artery (DEoxygenated blood from heart to lungs). Main Valves: Tricuspid valve (separated right atrium and ventricle to ensure correct flow of blood), Bicuspid Valve( separates left atrium and ventricle), Aortic Valve( ensures blood flow from left ventricle into aorta). hey sorry only saw ur question today:P hope it helps!
