三片式高平台内螺纹球阀

结构特点:由阀体、两个阀盖和球体等部件组成。这种三片式结构增强了阀门的稳定性,且便于拆卸、维修和更换,只需拆卸少量螺栓即可将阀门解体。


工作原理:通过旋转球体实现介质的通断。在关闭位置,球体受阀杆的机械施压作用,紧压在阀座上;逆时针转动手柄时,阀杆和球体也随着转动,使球体打开;关闭时,顺时针旋转手柄,阀杆和球体随之转动,球体再次紧压在阀座上实现关闭。


主要零件材料:阀体和阀盖可采用 WCB、CF8、CF8M 等材质,球体和阀杆可选用 304、316 等不锈钢材质,阀座一般采用 RPTFE 等材料,密封圈可使用 FKM 等。


连接方式:主要连接方式为内螺纹连接,阀门两端都有内螺纹,可与管道上的外螺纹相匹配,适用于较小口径的管道,安装和拆卸方便。


优点:具有流体阻力小、操作方便、密封性能好、耐腐蚀性强等优点,旋转 90° 即可实现全开或全关,操作扭矩小,适用于频繁操作的场合。

Products and services that meet fluid control requirements

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
