Butterfly valve, also called the flap valve is a kind of simple structure of the regulator, 

also can be used in low pressure pipeline medium valve butterfly valve in the switch 

control the way work is closed a (disc or disc) is a disk, around the axis of rotation to

achieve a valve open and close, mainly in the line cut off and throttling effect.

Butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotation 

around its own axis, so as to achieve the aim of opening and closing or adjust.

Introduction to the

Butterfly valve, butterfly valve) : also called butterfly valve worm gear
Definition: open-close part for disc butterfly plate and a valve body axis rotate.[1]
Structure: mainly by the valve body, valve stem, disc and seal ring.The body is 

cylindrical, short axial length, built-in butterfly plate.
Using range
Electric butterfly valve butterfly valve is suitable for the generator, gas, 

natural gas, liquefied petroleum gas, city gas, cold hot air smelting, chemical 

industry and power generation, environmental protection, such as, building

water supply and drainage engineering system of conveying a variety of corrosive,

non corrosive fluid pipe, used to adjust and block the flow of the medium.
Functional purposes
Pneumatic butterfly valve butterfly valve (English: butterfly valve) is to point 

to shut down a (disc or disc) is a disk, around the axis of rotation to achieve 

a valve open and close, mainly in the line cut off and throttling effect.Butterfly 

valve opening and closing is a disc-shaped butterfly plate, the body rotation around

its own axis, so as to achieve the aim of opening and closing or adjust.Butterfly valve 

fully open to the barrier is usually less than 90 °, butterfly valve and the adjustment 

lever itself has no self-locking ability, in order to butterfly plate positioning, to add 

worm gear reducer on the valve stem.The use of worm gear reducer, can not only 

make the butterfly plate with self-locking ability, make the butterfly plate to stop at

any position, also can improve the performance of the valve.Industrial specialized 

characteristic ability of high temperature butterfly valve, apply pressure range is higher also, 

nominal valve size is big, the body is made of carbon steel, valve plate seal using metal ring 

instead of rubber ring.Large high temperature butterfly valve USES the steel plate welding 

manufacturing, mainly for the duct smoke and gas of high temperature medium.

 


Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
Q: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
There is no electronic distributor on your caravan it uses a coil pack To the 1st poster there is no valve pan gasket you have valve cover gaskets. The fuel filter on your van is Incorporated in the fuel pump module located inside your fuel tank. There a several things that can contribute to sluggish performance, look at your exhaust and make sure it is not bent/collapsed/restricting Dodge Chrysler Jeep Tech
Q: Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(
here okorder /... usually you can tell when a car needs the gasket to be replaced because it will leak oil where the gasket is at the bottom of the cover i think hes ripping you off because cars usually dont need to have the valve cover replaced, just the gaskets so take it to another mechanic and get another estimate
Q: Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??
On solid lifters tappy is happy I don't have a manual here, but if you need to get it going now that phrase will help you.
Q: How to calculate the size of the manual butterfly valve?
1. The size of the installation fits only two: the length of the structure and the distance between the flanges.2, butterfly (Manual butterfly) butterfly plate installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. Butterfly valve has an elastic seal and metal seal, two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
Q: valve adjustment 2001 chev prism 1.8L
valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.
Q: Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
for every cylinder there is 4 valves..
Q: What's the difference between electric butterfly valve and electric two way valve?
Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.
Q: Butterfly valve D71X-16 and D71X-16Q what is the difference?
D71X-16 can be ductile iron, stainless steel, carbon steel, and so onD71X-16Q can only be ductile ironIt's material that has special requirements. It seems like this
Q: 1988 volkswagon cabriolet, rabbit tried mystery oil let sit for a week having trouble with stuck valves even taken a wrenrch to manually unstick. help any suggestions 4 cyclinder car has been sitting up for about 4 years
The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
