The function of the butterfly valve USES

Butterfly valve, also called the flap valve is a kind of simple structure of the regulator, can be used for low pressure pipeline medium of switch control butterfly valve is closed (disc or disc) is a disc, shaft rotation around the valve to open and close a valve, the valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. 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 (English: butterfly valve) refers 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.
