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:My cougar needs new EGR valve. They squeezed the 4.6 litre engine into it. My question is, how hard is it to get out and then back in? I can barely see the top of it behind the intake manifold so don't want to get it off and not be able to get it back in. What size bolts hold it in? I'm sure they are metric. Any help would be greatly appreciated.
- I would worry less about the mount bolts and more about getting the pressure fittings off. These can be a real bear if you haven't done a thousand of them. You may have to cut some cheap wrenches in half to gain access to them or use crowfoot wrenches or alot of heat without melting fuel lines, engine parts ect.
- Q:I pulled the vaccuum line off the valve and nothing happened. I revved the engine and held it a higher rpm and still nothing happened(no vaccuum). Does this mean that the egr valve is bad. I have been having a problem with rough idle, and keeping the car running at a stop sign. I have already changed the pcv valve and that seemed to help a little. Thanks
- You have likely got a bit of carbon in the EGR that you can clean after you remove it, I usually spray some penetrating oil into the valve hold my finger over the hole that I sprayed into and turn the valve over, if it leaks the seat is dirty and cleaning the carbon out may help. also push up on the plunger several times to be sure that it doesn't stick alternate carb cleaner with penetrating oil until the valve is free and no longer leaks when inverted. As far as your question the test you described doesn't test the EGR or the EGR solenoid correctly at all. On some the car needs to be in gear to actuate the EGR, all you need to do is check that there is vacuum to the solenoid and that the EGR valve works freely. If the EGR fails to work the check engine light should be on and you can check the code to get a clue as to why.
- Q:Hey Guy! So I Was Thinking About Buying A 93 Honda Del Sol For $1800, But The Guy State That It Need A Valve Job Now Im Not To Sure What Is A Valve Job Is And How Much It Would Cost... So Please Help Me Out... I Really Need A Car :-/If Needed I Live In South Of California
- The valves that allow gas into the cyllanders and exhaust the burned fuel are shot. Heads have to be removed and valves replaces, reground, whatever the mechanic needs to do to get the compression back to normal and the valves functioning. Could be rocker arms, a number of other internal parts. Probably going to cost about 1/2 what the car is selling for. Unless it is super clean and pretty low mileage otherwise: Pass
- Q:I've been diagnosed with mitral valve prolapse, my doctor just told me that i need to setup an appointment with the hospital to look at treatments for heart mitral valve prolapse-to possibly have a heart valve replaced. I am wondering if i should setup an appointment with mayo clinice in minnesota to get another opinion on that? I'm wondering if surgery is an only option available to me, i have been taking beta blockers that have been no help for the past 3-4 months. Thanks.
- at the start, you ought to talk on your typical practitioner. they might certainly answer your questions extra proper than all of us right here. yet, i can assist you be attentive to that your situation can certainly be very uncomplicated. I certainly have a kinfolk member with an identical ingredient and he leads an exceptionally frequent existence and could no longer desire a valve alternative. If he engages in very actual interest (alongside with taking part in soccer), he does get drained certainly, yet different than that, he's high-quality. In case they did no longer clarify it to you (it seems they weren't very informative) right here is going: Your mitral valve is nearly a sprint door that opens and closes on your heart. once you have a mitral vavle prolapse, what which ability is that as quickly as that valve swings close, it closes and definitely swings IN slightly too far. (Ever seen a swinging door? comparable thought) This reasons slightly a leak. it is a few thing which will ought to be checked each few years in the process your existence, to verify that it does not worsen. touch your typical practitioner and ask her or him those questions, just to be on the risk-free ingredient.
- Q:I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help

- Q:Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
- Plugged oil supply to valve train. Very serious.
- Q:Im trying to make an apparatus that would allow you to breathe in from one tube and exhale through another is their a valve that does this. I originally thought that a one way valve might work however I cannot find one that works with suction.
- Position two backflow preventers in oposite directions on your supply and exhaust line. connect them to a Tee fitting. the third end of the tee is where you will breathe
- Q:and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?
- A valve job involves removing the head from the engine, disassembling the head regrinding the valves seats and installing new valve seals guides. new engine vs. valve job? Depends on how many miles are on the original engine. It's seldom a good idea to do only a valve job on a hi mileage engine. Valve job would be cheaper at first, unless you plan on keeping the car for a long time, then a new engine would be a good choice. Maybe the guy was just setting you up to ask for a lower price?
- Q:I had a doctor who was suspicious of me having a heart valve problem. I don't want to be on medication for the rest of my life. I only want to change my diet, pray, exercise, and meditate. I don't believe the doctor has that cure for that problem that's if it was a heart valve problem.
- It depends on what sort of heart valve problem you have, how bad it is, and how bad the symptoms are. Sometimes you don't need to do anything special except watch the diet and lifestyle, sometimes you need medicine, and sometimes the cure is surgical repair or replacement of the valve. I think prayer is a fine thing to help, but the Lord also gave us the skills so doctors could provide something a little more physical. If your heart valve problem is bad enough, it can cause damage to your heart and the rest of your body that all the prayer, diet, exercise and meditation in the world won't help fix. However, as a patient, it's always your decision if you want to take the doctor's advice or not. Otherwise you could find yourself dead, and explaining to God why you chose not to take the help He provided for you. So before you go making any decisions, you need to wait until you find out what the entire story is. Then weigh up all your options carefully,and decide.
- Q:what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?
- If it is an outboard 2 stroke there are no vlaves to adjust, it uses reeds in the intake. If it is any type of 4 stroke get a repair manual for proper specs.
