I. Introduction of H41N Lifting Check Valve

H41N lift check valve (horizontal check valve) structure diagram-Hushan Valve Manufacturing (Shanghai) Co., Ltd.

    具有结构简单,动作可靠,维修方便等优点,广泛应用于净化设备、石油、化工、冶金、电力、轻纺等生产过程中当介质由阀体箭头所示流向进入阀体,介质的压力作用在阀瓣上产生向上的推力,当介质推力大于阀瓣重力时,阀门打开。 H41N lifting check valve has the advantages of simple structure, reliable operation and convenient maintenance. It is widely used in the production process of purification equipment, petroleum, chemical industry, metallurgy, power, textile, etc. When the medium flows into the valve body as shown by the arrow The pressure of the medium exerts an upward thrust on the valve flap. When the medium thrust is greater than the gravity of the valve flap, the valve opens. When the force exerted by the pressure of the medium behind the valve on the disc plus the gravity of the valve itself is greater than the force exerted by the pressure before the valve on the disc, the valve is closed to prevent the medium from flowing backward. 可按用户要求设计制造不同结构形式和连接形式的止回阀,为各种设备配套使用。 H724X-float ball valve can be designed and manufactured in different structures and connection types according to user requirements, for supporting the use of various equipment.
