焊接高温高压止回阀(螺纹高温高压逆止阀)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Welding high-temperature and high-pressure check valves (threaded high-temperature and high-pressure check valves) increase the sealing pre tightening force of the valve disc through the compression deformation of the spring, making the initial sealing more reliable. When the pressure of the inlet medium is greater than the compression force of the spring, the valve disc moves towards the opening direction. At this time, the valve opens, and fluid flows into the valve through the guide groove; When the pressure at the inlet end decreases, the valve disc is closed, and combined with the pressure of the medium reflux, the specific pressure of the valve disc meets the sealing requirements and forms a seal
