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:What are the major disadvantages of butterfly valves?
- Shortcoming:A. operating torque is large, such as larger diameter or high pressure, it needs to be equipped with larger actuators;B. leakage is large, ordinary type is 2%C;C. as the adjustment of some butterfly valve, its rotation angle is limited to 60. Adjustable range is small.
- Q:does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?
- The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
- 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.
- Q:What does the triplex of pneumatic butterfly valve mean?
- Air pressure reducing valve, filter, oil mist these three parts
- Q:can't locate freon intake valve for 03 jaguar an was wondering were it is located at
- Most manufacturers put the fill nozzle on the hoses, either the high or/and the low side. Also, the low side can be found on the accumulator.

- Q:Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??
- Only way to be sure is to put clay on top of a piston and turn the engine over by hand and then measure the clearance on the indentation in the clay.
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- Worm gear flange butterfly valve, also known as worm gear flange plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.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. Butterfly valve plate installed in the direction of the diameter of the pipe. 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. When the flange butterfly valve is in the fully opened 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 that the flow control characteristic is better. Butterfly valve with bullet sealing and metal sealing two seal type. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
- Q:Does the pneumatic butterfly valve need electricity?
- Definitely need control, so be sure to have electricity. You can control the switch on and off. If necessary, this valve can contact me.
- Q:What are the uses and classifications of manually operated clip butterfly valves?
- Classification: butterfly valves are commonly used on the clip butterfly valve and flange butterfly valve two. The clip type butterfly valve is connected with the two pipe flange with a stud bolt. The flange type butterfly valve is provided with a flange on the valve, and bolts are used to connect the flanges at the ends of the valve to the pipe flange.
