进口高温高压Y形截止阀，进口工艺阀性能描述 Performance description

高温高压Y形截止阀(工艺阀)的阀瓣与阀杆设计为一体结构,流道与管道成一斜线,阀座密封面采用锥形结构,其优点是介质对密封面的冲刷小,不易存留杂质,减少密封面磨损和擦伤,对密封面起一定的保护作用 RETZ The valve clack and valve stem of high-temperature and high-pressure Y-shaped stop valve (process valve) are designed as an integral structure, the flow passage and pipeline form an oblique line, and the sealing surface of the valve seat adopts a conical structure. Its advantage is that the medium has less erosion on the sealing surface, is not easy to retain impurities, reduces the wear and scratch of the sealing surface, and plays a certain role in protecting the sealing surface

设计特点 Design features

阀门设计整体锻造方式，无泄漏 The valve is designed to be integrally forged without leakage

不旋转阀杆可以在超高压和超高温，并确保紧密关闭压力 Non rotating valve stem can operate under ultra-high pressure and ultra-high temperature, and ensure tight closing pressure

上下阀杆减少操作扭矩，钨铬钴合金阀座耐高温冲刷，阀杆和阀体相扣设计，确保阀杆不脱离阀体 The upper and lower valve stems reduce the operating torque, the stellite valve seats are resistant to high temperature scouring, and the valve stem and valve body are designed to be interlocked to ensure that the valve stem does not leave the valve body

压盖衬套为重型设计，可更换填料压盖衬套设计 Gland bushing is heavy duty design, replaceable packing gland bushing design

Y型设计符合最好的介质流动特性 Y-shaped design conforms to the best medium flow characteristics
