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.
Structure: mainly by the valve body, valve stem, disc and seal ring.The body is
cylindrical, short axial length, built-in butterfly plate.
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.
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.
