安全(quán)閥(fá)廣泛應用于建(jiàn)材、冶金、煤碳、熱電等(děng)行業。它用于倉庫頂因物(wù)理變化而産生的内壓，易爆(bào)氣體的排(pái)放及安全防範。
The valve is widely used in building material, metallurgy, coal carbon and thermoelectricity industries etc. It is applied in top of storage where inner pressure is made because of physics change, the let-off of easy-exploding and safety prevention.
