Description
Technical Field
The utility model relates to a long-term sealed medical gas safety valve field, concretely relates to long-term sealed medical gas safety valve.
Background
The gas safety valve is divided into the following structural forms: can be divided into a closed type and an open type. The closed safety valve is used for discharging the discharged medium to a designated place along an outlet without leaking, and is generally used in toxic and corrosive media. For the safety valve for air and steam, a non-closed safety valve is basically used. The existing closed medical gas safety valve has poor sealing performance, leads to early pressure relief, and particularly does not increase pressure when the pressure is high, so that the working pressure required at present cannot be achieved.
