QJ641M 型气动带手轮高温球阀概述: I. Overview of QJ641M pneumatic high temperature ball valve with handwheel:

型气动带手轮高温球阀是采用新型密封材料为阀座 , 经同类产品聚四氟乙烯做密封的球阀 , 使用寿命提高了 3-5 倍。 QJ641M pneumatic high temperature ball valve with handwheel is a new type of sealing material using PTFE as the valve seat . The service life is increased by 3-5 times. 沪山 牌高温球阀与截止阀、柱塞阀、排污阀,结构长度相符,扩大了球阀使用范围,广泛用于石油、化工、橡胶、造纸、制药等行业,可替代截止阀、柱塞阀、快速排污阀。 It has the advantages of stable performance, reliable sealing, low friction, light switching, high temperature resistance, wear resistance, oil resistance, corrosion resistance, long service life, etc., " Hushan " brand high temperature ball valve and globe valve, plunger valve, sewage valve, structure Matching the length, expanding the use of ball valves, widely used in petroleum, chemical, rubber, paper, pharmaceutical and other industries, can replace globe valves, plunger valves, quick blowdown valves. ≤350℃ Applicable medium: acid such as water, steam, heat-conducting oil, operating temperature: ≤350 ℃  

QJ641M 型气动带手轮高温球阀结构特点及作用原理: Second, QJ641M pneumatic high temperature ball valve with handwheel structure characteristics and function principle:   

      The ball and sealing ring of the pneumatic ball valve adopts special processing technology and the latest sealing materials, so that the surface roughness and roundness of the ball can meet the standard requirements, thereby improving the sealing performance, service life and high temperature resistance. Turn the handle clockwise to drive the valve stem to drive the ball to rotate and the medium to pass through.
