D341J desulfurization butterfly valve is suitable for pipelines transporting various corrosive and non corrosive fluid media in engineering systems such as furnaces, coal gas, natural gas, liquefied petroleum gas, city gas, cold and hot air, chemical smelting, and power generation environmental protection. It is used to regulate and cut off the flow of media
Functional purpose
Butterfly valve refers to a type of valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing. It is mainly used for cutting off and throttling in pipelines. The butterfly valve opening and closing component is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening, closing, or adjusting. The fully open and fully closed butterfly valve is usually less than 90 °, and the butterfly valve and stem themselves do not have self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the stem. By using a worm gear reducer, not only can the butterfly plate have self-locking ability to stop at any position, but it can also improve the operational performance of the valve.
The characteristics of industrial butterfly valves are high temperature resistance, high pressure range, large nominal diameter, carbon steel valve body, and metal ring instead of rubber ring for valve plate sealing. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used for flue gas ducts and gas pipelines for high-temperature media.
