進(jìn)口自力式壓力差壓組合閥的分類及選型依據(jù)德國洛克 

一、進(jìn)口自力式壓力差壓組合閥描述：

德國《LOCKE》洛克進(jìn)口自力式壓力差壓組合閥由兩個執(zhí)行器和兩個設(shè)定壓力的彈簧組合。適用于非腐蝕性的液體、氣體和蒸汽在系統(tǒng)管道中的壓力或壓差控制。可用于最高300℃的非腐蝕性的液體、氣體和蒸汽等介質(zhì)，按優(yōu)先動作的原理工作,不能同時控制兩個參數(shù)。

The self operated pressure differential pressure combination valve imported from Germany "locke" is composed of two actuators and two springs with set pressure. It is suitable for pressure or differential pressure control of non corrosive liquid, gas and steam in the system pipeline. It can be used for non corrosive liquid, gas and steam with the maximum temperature of 300 ℃. It can work according to the principle of priority action, and can not control two parameters at the same time.

二、進(jìn)口自力式壓力差壓組合閥結(jié)構(gòu)特點： 

1、采用波紋管+彈簧做壓力平衡元件，靈敏度高;

2、嗓音低性能可靠，免于維修;

3、通過組合件，可進(jìn)行多項組全控制;

4、采用標(biāo)準(zhǔn)模塊設(shè)計;

1. Bellows and spring are used as pressure balancing components with high sensitivity;

2. Low voice, reliable performance, free from maintenance;

3. Through the assembly, multiple groups can be fully controlled;

4. Standard module design is adopted;
