►描述--

RETZ进口高温高压止回阀阀瓣、阀座密封面采用铁基合金或司太立钴基硬质合金堆焊面成,硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好使用寿命长等特点。不锈钢销轴与阀瓣连接采用内装式结构、性能优良、密封更可靠

RETZ imported high temperature and high pressure check valve disc and seating seal face are made of iron base alloy or Sli cobalt based hard alloy surfacing surface. It is characterized by high hardness, abrasion resistance, high temperature resistance, corrosion resistance, good abrasion resistance and long service life. The stainless steel pin and disc are connected with internal structure, excellent performance and reliable sealing.

►原理--

进口高温高压止回阀阀瓣通过弹簧的压缩变形来增加阀瓣的密封预紧力,使初始密封更加可靠,当进口端介质压力大于弹簧的压缩力时,阀瓣向开启方向移动,此时阀门打开,流体通过导流槽流入阀后;而当进口端压力降低时,阀瓣封闭,再加上介质回流的压力,使阀瓣比压达到密封要求而形成密封。

►用途--

进口高温高压止回阀通常用于石油、化工、天然气、冶金、电力、化纤、锅炉、造纸、城建、等领域的水、天然气、导热油、蒸汽等介质的管路上,作为介质流量和压力的启、闭装置。
