三通球阀

【产品用途】
Q45F 型 PN16~PN40 T形三通球阀有T形和L形。T形能使三条正交的管道相互联通和切断第三条通道,起分流、合流作用。L形只能连接相互正交的两条管道,不能同时保持第三条管道的相互连通,只起分配作用。


【产品特点】
1、三通球阀在结构上采用一体化结构,4面阀座的密封型式,法兰联接少,可靠性高,设计实现了轻量化。
2、三通球芯分T形和L形,使用寿命长,流通能力大,阻力小。
3、球阀按作用式分单作用和双作用两种型式,单作用式的特点是一旦动力源发生故障时,球阀将处于控制系统要求的状态。

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.
