Safety relief valve

Abstract

The invention discloses a safety pressure relief valve, comprising: a valve seat, a valve body and a valve core, one end of the valve seat is an end face, the other end is open, an air inlet is arranged on the end face of the valve seat, the valve The open end of the seat is provided with an internal thread interface; one end of the valve body is an end face, and the other end is open, the end surface of the valve body is provided with an exhaust port, and the open end of the valve body is provided with an external thread interface, so The opening end of the valve body is threadedly connected with the opening end of the valve seat; the valve core is in the shape of a straight cylinder, the outer wall of the valve core is slidingly fitted with the inner wall of the valve body, and the valve core is provided with As for the safety diaphragm, a coil spring is arranged between one end of the valve core facing the valve body and the end surface of the valve body. The safety pressure relief valve disclosed by the invention can not only discharge leaked trace gas in time, but also discharge ultra-high pressure gas generated by the system in time when in use, and play a role of safety protection for the fire extinguishing system.

Description

technical field [0001] The invention belongs to the field of fire-fighting facilities and relates to a safety relief valve. Background technique [0002] There is often leakage gas in the pipeline of the fire extinguishing system. If the leaked gas cannot be discharged in time, it may cause the fire extinguishing system to misspray; and in the quasi-working state, the fire extinguishing system is easily affected by the ambient temperature or other factors. This causes its compressed gas to expand, causing the system piping to burst due to a sudden increase in internal pressure. Contents of the invention [0003] In order to solve the above problems, the present invention provides a safety pressure relief valve, which has a simple structure and reliable performance, and can discharge gas in time when the system pipeline generates gas leakage or high pressure, thereby protecting the fire extinguishing system. [0004] In order to achieve the above object, the present invent...
