First, the introduction of new lining check valve


Lined new type check valve

阀瓣都是围绕阀座外的(销)轴、镶嵌在阀体与阀盖之间形成的特殊凹槽内、启闭灵活,密封可靠,另外新型止回阀的特点是:除了阀体,阀瓣外,复位弹簧也全部包衬了耐腐蚀的氟塑料, H44N旋启式止回阀 设计合理的弹簧,使阀瓣在低压区内也能产生足够的密封比压,保证阀门在低压力区密封的可靠性。 The new check valve lining of the lining is around the (pin) shaft outside the valve seat, embedded in a special groove formed between the valve body and the valve cover, flexible opening and closing, reliable sealing, and the new check valve is characterized by : In addition to the valve body and the valve disc, the return spring is also fully lined with corrosion-resistant fluoroplastics. The H44N rotary check valve has a reasonably designed spring, so that the valve disc can also produce sufficient sealing specific pressure in the low pressure area. To ensure the reliability of the valve seal in the low pressure zone.
