GYA液壓安全閥

1、  液壓式安全閥是（活瓣式）呼吸閥的安全備用設備，它的吸氣和呼氣的動作壓力略高于（活瓣式）呼吸閥一量失靈或在冬季其活瓣凍結(jié)時，液壓安全閥的液封即被破環(huán)從而保護油罐免遭破環(huán)。

2、  液壓安全閥裝于油罐頂部與呼吸閥配合使用。

3、  控制壓力：+56毫米水柱至-50毫米水柱。

1.     liquid-pressure style safety valve is a assistant equipment of the breathing valve(moving disc style),the active pressure of aspera-tion and expiration is higher than breathing valve(moving disc style ),asupon once the breathing valve does not work in winter ,the moving disc will de frozen,the liquid seal of the liquid –pressure style safety valve can be broken for protecting the oil tank.

2.     liquid-pressure safety valve will beinstalled in top of oil tank and assorted used with breathing valve.

3.     the control pressure:+56mmwater columm to-50mmwater columm.
