進口高溫高壓Y形截止閥，進口工藝閥性能描述 Performance description

高溫高壓Y形截止閥(工藝閥)的閥瓣與閥桿設計為一體結構,流道與管道成一斜線,閥座密封面采用錐形結構,其優點是介質對密封面的沖刷小,不易存留雜質,減少密封面磨損和擦傷,對密封面起一定的保護作用 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

設計特點 Design features

閥門設計整體鍛造方式，無泄漏 The valve is designed to be integrally forged without leakage

不旋轉閥桿可以在超高壓和超高溫，并確保緊密關閉壓力 Non rotating valve stem can operate under ultra-high pressure and ultra-high temperature, and ensure tight closing pressure

上下閥桿減少操作扭矩，鎢鉻鈷合金閥座耐高溫沖刷，閥桿和閥體相扣設計，確保閥桿不脫離閥體 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

壓蓋襯套為重型設計，可更換填料壓蓋襯套設計 Gland bushing is heavy duty design, replaceable packing gland bushing design

Y型設計符合最好的介質流動特性 Y-shaped design conforms to the best medium flow characteristics
