RETZ瑞茨『进口高压法兰球阀』详细介绍●RETZ球阀系列●RETZ高压法兰球阀●产品数据
?进口高压法兰球阀描述--
RETZ高压法兰球阀材料是锻造出来的，材质的密度比铸造的密度要大很多，特别适合高压球阀的制造加工高压锻钢球阀关闭件球体绕阀体中心线作旋转来达到开启、关闭的一种球阀，密封件嵌于不锈钢阀座内，金属阀座尾端设有弹簧，当密封面磨损或者烧毁时，在弹簧作用下推动阀座与球体形成金属密封。其具有独特的自动泄压功能，当阀门中腔介质压力超过弹簧预紧力，出口端阀座后退脱离球体，达到自动泄压效果，泄压后阀座自动复位.
RETZ high pressure flange ball valve material is forged. The density of material is much larger than that of casting. It is especially suitable for the manufacture and processing of high pressure ball valve. A ball valve that turns around the center line of the valve body of the high pressure forging ball valve is made to open and close. The seal is embedded in the stainless steel seat and the end of the metal seat is set at the end of the valve seat. When the sealing surface is worn or burned, the spring pushes the valve seat and the ball to form metal seal under the action of the spring. It has a unique automatic pressure relief function, when the medium pressure of the valve in the valve is more than the spring pretightening force, the outlet valve seat back out of the ball, to achieve the automatic pressure relief effect, the valve seat automatically reset after pressure relief.
?进口高压法兰球阀产品特点--
1.本产品所有部件均为锻件
2.采用下装式阀杆,设备倒密封结构
3.采用镶嵌式阀座,阀座背后设备O型圈,确保介质不外漏
4.密封面采用尼龙,自然滑性材料,但抗弯曲强度和冲击强度及较高的延性，与金属不相上下
5.标准阀座采用弹簧结构，将阀座推向球体，保证了良好的进出口双向密封性能；
6.枢轴采用防吹出保护，有效地防止泄漏；低磨擦系数的轴承，使得扭矩减少到，便于阀门启闭；
7.阀杆与阀体有效的接触，使防静电接地装置性能优越等。
