Temperature pressure safety valve

Abstract

The utility model relates to the technical field of valves, and discloses a temperature and pressure safety valve which comprises a valve body, a valve seat, a first pressure relief assembly, a temperature sensing element and a fixing piece. The valve seat and the valve body are integrally formed in the valve body, a hollow inlet is defined by the valve seat, and the medium inlet is communicated with the first pressure relief opening through the inlet; the first pressure relief assembly abuts against the inlet of the valve seat and is used for opening / closing the inlet. The second end of the ejector rod of the temperature sensing element can penetrate through the inlet of the valve seat and abut against the first pressure relief assembly so as to push the first pressure relief assembly to move to open / close the inlet. The fixing piece is detachably installed between the inner wall of the valve body and the temperature sensing element and used for fixing the temperature sensing element and the valve body. According to the temperature and pressure safety valve, the valve body and the valve seat do not need to be integrally formed with a fixing piece with a precise and complex structure, machining is easy, and therefore the machining efficiency of the valve body can be improved, and the machining cost can be reduced.
