进口卧立两用止回阀 无泄漏高温逆止阀 蒸汽导热油止回阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/美国，我们一直致力于流体控制领域的持续创新，始于2005……

　　卧立两用式止回阀密封性强、无噪音、能自动控制管道介质倒流及自动关闭，卧立管道皆可安装。The horizontal and vertical dual purposecheck valve has strong sealing performance, no noise, and can automaticallycontrol the backflow of pipeline medium and close automatically. It can beinstalled in both horizontal and vertical pipelines

　　卧立两用止回阀是靠介质顺流时的压力压缩螺旋弹簧，但螺旋弹簧不与介质直接接触的状态下，即可开启，介质通过；当介质压力无法压缩螺旋弹簧，介质逆流压力和弹簧的作用关闭阀瓣The horizontal and vertical dual purposecheck valve compresses the spiral spring by the pressure of the medium flowingdownstream, but the spiral spring can be opened without direct contact with themedium, allowing the medium to pass through; When the medium pressure cannotcompress the spiral spring, the reverse flow pressure of the medium and theaction of the spring close the valve disc
