H44H美标旋启式止回阀是根据美标ANSIB16.34,美石油学会标准API16D要求。用于Class 150LB压力的水、油品、蒸汽等管道系统,用于防止介质倒流。广泛应用于化工、冶金、制药等多个领域。

Working Principle

H44H美标旋启式止回阀采用内装摇臂旋启式结构,阀瓣绕转轴作旋转运动,靠介质流动推开阀瓣,介质通过;当介质倒流时,阀瓣靠自身重量以及倒流介质的作用,关闭阀门。

  • 可采用各种配管法兰标准及法兰密封型式,满足各种工程需要及用户要求。
  • 阀体材料品种齐全,垫片可根据实际工况或用户要求合理选配,能适用于各种压力、温度及介质工况。
  • 阀瓣、阀座密封面采用铁基合金或司太立(Stellite)钴基硬质合金堆焊面成,耐磨、耐高温。
