高压波纹管密封截止阀

英文名称：High pressure bellows seal valve

一、阀门型号：WJ41H-40C

二、高压波纹管密封截止阀说明介绍：

我厂是在上海专业生产波纹管密封截止阀的厂家，本产品采用碳钢阀体制造，阀门采用高压阀体，可耐高压，阀门的密封采用石墨和金属密封，具有极强的耐高温性能，且阀门主要应用于高温蒸汽、高温石油燃气等介质。此产品采用法兰凹面连接，阀门连接在管道上更加安全可靠。

三、高压波纹管密封截止阀的基本工作原理：

高压波纹管密封截止阀的工作原理是通过手动转动阀门的手轮，阀门的手轮带动阀杆的转动升降阀门的阀座密封；当阀门处于关闭状态时，转动手轮，升起阀门的阀杆，阀杆带动阀座升起，介质就可以通过阀门；当阀门处于开启状态时，转动手轮，降下阀座，阀门依靠阀座和阀门底座密封的挤压，达到良好的密封效果，阻止介质通过。
