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:Which is more expensive, gate valve or butterfly valve?: Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.

Q:I did a compression check on my 350 chevy. I have low compression of 175psi on one cylinder.The other seven cylinders range from 195psi to 205psi Could the valves be too tight on the cylinder with 175 psi compression?: unless they have been tampered with that wouldn't be it,they usually wont tighten up on their own,i would suspect maybe a valve with a slight burn place on it that's causing that to happen or a ring causing you to loose that much compression,try adding a small amount of oil in the cylinder and then do the compression test again,that will tell you if its a ring or a valve,that's a big loss of compression ,and when you see that much of drop its usually a burnt valve.good luck.

Q:butterfly valves d7a1x5: D71x-1.6? Or D371X-1.6, do you need butterfly valves for production or butterfly valves? The question perplexed us all.

Q:What type of valve does the butterfly valve D343X DN300 represent?: D butterfly valve, 3 worm gear, 4 flange type, 3 should be three eccentric X body, sealing surface for rubber, DN300 caliber 300MM

Q:Butterfly valve in use when should pay attention to what problems?: In the process of using power pipe pneumatic butterfly valve, the need to pay attention to these problems, the first is to conduct a comprehensive inspection in the use of butterfly valve, check butterfly valve is in good condition, all parts are connected in place, the valve is loose and so on, wait to ensure that everything is normal, it can make an official use.

Q:The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30: Crown valve pressThere is no standard answer to this question. I can only give you my personal opinionRiser butterfly valve is generally place in these places (the pump outlet valve, drainage system, upper and lower floors) riser are basically installed butterfly valve, butterfly valve is not cheap, fast speed is fast closing butterfly valve can be quickly closed and open educationYou see the water pipe installed valve (with all the cross tube is the basic gate) explanation, because in contrast to the quality and stability, the valve will be better, the site does not need fast switching, it will choose good stability point gateSum upThe drains are all butterfly valves, and the stabilizing pipes are all valves! (do not rule out a full use butterfly valve for stealing work)

Q:My bike has now 6200 miles on the odometer. The manual says that a valve adjustment should be performed every 6000 miles. But the bike runs fine. Can I just have the valve checked or should I have them adjusted even though the bike is fine? What will happen if I just keep riding it?: In reality, lots of bikes go their entire lives without a valve adjustment. In my opinion that is a great way to ruin a bike though. They have a maintence schedule for a reason. If a valve isn't seating, it can hurt performance and the valve will not be able to transfer heat to the head. That can burn a valve and cause detonation. You have to check valves to adjust them, and the labor for just checking will be nearly the same or identical to doing the adjustments. I do all my own wrenching, so money isn't really an issue, but if I were you, I would just bite the bullet and take it in.

Q:The difference between butterfly valve and gate valve: Butterfly valve role, butterfly valve is used to open and close disk type reciprocating rotation of about 90 degrees to open, close or adjust the flow of a medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive.

Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!: HI i have question is all EGR valve work the same ? I Have an 86 Rx7 and when I test the EGR valve is doesn t hold pressure. So I m curios are they different from other vehicle due to is a rotary engine or due they all work the same. Thank You.

Q:D what's the meaning of "one 71x one 1 butterfly"?: According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
