Gate valve (gate valve) is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate.
The structure of editor mainly composed of a valve body, a valve rod and a butterfly plate and a sealing ring. The valve body is cylindrical, with short axial length.
The working principle of butterfly valve butterfly plate driven by the stem editor, if turned 90 degrees, will be able to complete a hoist. Change the deflection angle of the butterfly plate, you can control the flow of media.
Working condition and medium: butterfly valve used in furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, metallurgical and chemical industry and environment-friendly power generation, building to drainage engineering system transport all kinds of corrosive and non corrosive fluid pipe for regulating and truncated medium flow.
Butterfly valve uses edit (English: butterfly valve butterfly valve refers to close (valve or butterfly valve plate) for the disc, around the valve axis of rotation to achieve the opening and closing a valve, in the pipeline mainly cut off and throttling action. Butterfly valve opening and closing parts is a disc - shaped disc, in the body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Valve fully open to fully closed is usually less than 90 DEG, butterfly and Butterfly Bar itself is not self-locking capability, in order to position the disc to install the valve stem on the worm gear reducer. Using worm gear reducer, not only can make the butterfly board with self locking ability, so that the butterfly board to stop at any position, but also to improve the operating performance of the valve. Special butterfly valve for industrial characteristics can resist high temperature and high applied pressure range, the valve nominal through large diameter, and the use of carbon steel valve manufacturers, valve plate sealing ring using the metal ring instead of rubber ring. Large high temperature butterfly valve using steel welding manufacturing, mainly used for high temperature flue gas channel and gas pipe.
