&Butterfly valve: Butterfly valve, also called flap valve, is a regulating valve with a simple structure. It can also be used as a square valve for switching control of low-pressure pipeline media. Butterfly valve means that the closing part (valve disc or butterfly plate) is a disc, surrounded by A valve whose shaft rotates to open and close. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. Butterfly valve (English:) refers to a valve whose closing part (valve disc or butterfly plate) is a disc and rotates around the valve axis to open and close. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The distance from fully open to fully closed of a butterfly valve is usually less than &. The butterfly valve and butterfly rod themselves do not have self-locking capabilities. In order to position the butterfly plate, a worm gear reducer must be installed on the valve rod. The use of worm gear reducer not only makes the butterfly plate self-locking, allowing the butterfly plate to stop at any position, but also improves the operating performance of the valve. The characteristics of the industrial butterfly valve are that it can withstand high temperatures, has a high applicable pressure range, has a large nominal diameter, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used in flue ducts and gas pipelines for high-temperature media.
