三通阀[THREE WAY VALVE]

三通阀：诞生于50年代。三通阀有3个出入口与管道相连，相当于两台单座阀合成一体。三通阀最早是用于代替两台单座阀投入系统使用。三通阀分为合流和分流两种。三通阀有3个出入口与管道相连，相当于两台单座阀合成一体；使用三通阀时，可省掉一个两通阀和一个三通接管。三通合流阀有两个入口，一个出口，将两种介质混合成第三种介质。三通分流阀有一个入口，两个出口，将一种介质经过阀后分成两路。

Three-way valve : born in the 1950s. Three-way valve has three entrances and pipes, equivalent to two single-Block valves synthetic one. Three-way valve is used to replace two single-Block, the first valve input system. Three-way valve into two hands and streaming. Three-way valve has three entrances and pipes, equivalent to two single integrated Block valves; Use three-way valve, a two-valve and can be saved over a three links. Convergence devices have two three links entrance, a export, two medium mixed into the third medium. Three links a triage valves entrance, the two exports, a medium through valves will be divided into two after the road.

（1）三通阀可代替两台互为开关的两个两通阀使用，可省掉一个两通阀和一个三通接管。（2）三通阀常用于热交换系统旁路调节，也可以做简单配比调节。（3）三通阀使用介质温度应小于300℃，两种介质温度差应小于150℃。（4）三通阀更换气开气闭时，必须更换执行机构。（5）DN＜80时，合流阀也可做分流阀用。

(1) The three-way valve to replace two mutually switches two two-valves used to save a two-valve and a three links takeover. (2) The three-way valve used to regulate heat exchange system exists, can do simple limited regulation. (3) three-way valve used to be less than 300 degrees medium temperature, two medium temperature less than 150 degrees should be poor. (4) The three-way valve replacement gas to gas shut, the executing agency must be replaced. (5) DN <80, Convergence valves also do triage valves.
