Butterfly valve, also known as flap valve, is a simple structure of the control valve can be used for low-pressure pipe media switch control butterfly valve is closed (disc or butterfly plate) for the disc, around the valve shaft rotation to achieve the opening and closing A valve that can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal, and radioactive media.Butterfly Valve
In the pipeline from the main cut off and throttling effect. Butterfly valve opening and closing parts 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 adjustment.
Butterfly plate driven by the stem, if turned 90 °, will be able to complete an opening and closing. Change the deflection angle of the butterfly plate, you can control the flow of the media.Butterfly Valve
Use of working conditions and media: butterfly valve for the furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection, building drainage and other engineering systems to transport a variety of corrosive, non-corrosive fluid Medium pipe, used to adjust and cut off the flow of media.Butterfly Valve
Butterfly valve refers to the closure (disc or butterfly plate) for the disc, around the valve shaft rotation to achieve the opening and closing of a valve, the main cut off and throttling on the pipeline. Butterfly valve opening and closing parts 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 adjustment.Butterfly Valve
Butterfly valve fully open to the whole is usually less than 90 °, butterfly valve and butterfly rod itself does not have self-locking ability, in order to butterfly plate positioning, to install the worm on the stem reducer. The use of worm reducer, not only can make the disc with self-locking ability, so that the butterfly plate to stop at any position, but also improve the valve operating performance.
Industrial special butterfly valve features: high temperature resistance, suitable for a higher pressure range, the valve nominal diameter, the valve body made of carbon steel, valve plate ring with metal ring instead of rubber ring. Large-scale high-temperature butterfly valve made of steel welding, mainly used for high-temperature media, smoke duct and gas pipeline.
