Butterfly valve, abbreviated as butterfly valve, refers to a type of valve in which the closing part (disc or disc) is a disc that rotates around the valve axis to achieve opening and closing. It mainly serves as a shut-off and throttling valve on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting.
Butterfly valve, abbreviated as butterfly valve, refers to a type of valve in which the closing part (disc or disc) is a disc that rotates around the valve axis to achieve opening and closing. It mainly serves as a shut-off and throttling valve on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting. The butterfly valve is usually less than 90 ° from fully open to fully closed, and the butterfly valve and stem do not have self-locking ability. In order to position the butterfly plate, a worm gear reducer needs to be installed on the valve stem. The use of a worm gear reducer not only enables the butterfly plate to have self-locking ability and stop at any position, but also improves the operational performance of the valve .
The characteristics of industrial butterfly valves are high temperature resistance, high pressure range, large nominal diameter, carbon steel 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 smoke and air ducts and gas pipelines in high-temperature media.
