产品型号：ZJHF（H）型
产品名称：ZJHF型气动三通薄膜合流阀
产品特点：ZJHF（H）气动三通调节阀有合流和分流两种结构形式。阀芯结构采用圆筒薄壁窗口，并采用阀芯侧面导向，三通阀在某些场合可以替代两个二通阀和一个三通接管而等到广泛应用，常用于热交换器的两相调节，也可用于简单的配比调节。公称通径和压差较小时，合流阀可用于分流场合，可互换使用，但公称通径大于80mm和压差较大的分流场合，不能互换使用。

Model: ZJHF （H）-type
Product Name: ZJHF type pneumatic three-film mixing valve
Features:ZJHF （H） pneumatic three-way diverting valve has two structural forms and confluence. Thin-walled cylinder valve structure using the window, and the use of spool side oriented, three-way valve in some cases can replace the two two-way valve and a three-way over and wait until the widely used, commonly used in heat exchangers of the two-phase adjustment can also be used for a simple ratio adjustment. Nominal diameter and pressure is small, the mixing valve can be used for streaming applications, are used interchangeably, but the nominal diameter greater than 80mm and larger shunt pressure situations, can not be used interchangeably.
