The overall material of the safety valve is made of high-quality stainless steel. After cryogenic processing, it is processed and assembled. It adopts a fully-closed bonnet and bonnet structure. When the safety valve is opened and discharged, the medium will not leak to the outside, and all are discharged through the drain pipe It can prevent dust and other impurities from entering the valve. It is suitable for low-temperature conditions of temperature -196 ~ 200 ° C as an overpressure protection device. The low temperature safety valve is mainly used in low temperature liquid medium systems such as liquid oxygen (liquid nitrogen, liquid argon), and has the characteristics of free start, reliable sealing and stable take-off pressure.
