How to repair the electric welded butterfly valve in Anshan if it is not closed tightly? Compared with other types of valves, pneumatic ball valves have the following advantages: angular stroke output torque, quick opening, stable and reliable, wide application, and the following.
Anti static function: set a spring between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
Long service life: because materials such as polytetrafluoroethylene have good self-lubricating property and small friction loss with the ball, the pneumatic ball valve is.
Small fluid resistance: pneumatic ball valve is the one with the smallest fluid resistance among all valve categories. Even the reduced diameter pneumatic ball valve has relatively small fluid resistance.
、 The structural characteristics of the electric ball valve mainly determine the assembly, repair and maintenance methods, which are part of the structural characteristics of the product. The structural characteristics mainly include: assembly size and overall height, pipe connection methods, such as flange structure, internal thread connection, circular hoop connection, internal and external thread connection, welding port connection, closed style, For example, inlaid ring, internal threaded ring, stacking welding, spray welding, shell body, valve rod substructure, mainly including rotary rod and lifting rod.
