一、產(chǎn)品詳細資料Product Details：
產(chǎn)品型號：ZJHF(H)型
產(chǎn)品名稱(chēng)：ZJHF型氣動(dòng)三通薄膜合流閥
產(chǎn)品特點(diǎn)：ZJHF(H)氣動(dòng)三通調節閥有合流和分流兩種結構形式。閥芯結構采用圓筒薄壁窗口，并采用閥芯側面導向，三通閥在某些場(chǎng)合可以替代兩個(gè)二通閥和一個(gè)三通接管而等到廣泛應用，常用于熱交換器的兩相調節，也可用于簡(jiǎn)單的配比調節。公稱(chēng)通徑和壓差較小時(shí)，合流閥可用于分流場(chǎng)合，可互換使用，但公稱(chēng)通徑大于80mm和壓差較大的分流場(chǎng)合，不能互換使用。
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.
