The application discloses a high-temperature gas
safety valve with pressure relief protection and relates to the field of safety valves.The
safety valve housing is provided with an inlet at the left side, and an outlet at the bottom; a pressure relief
pipe is communicated with the right outer wall of the
safety valve housing, a liquid cooling delivery box is fixedly installed at the lower end of the pressure relief
pipe, a one-way gas outlet
nozzle is installed at the right end of the pressure relief
pipe, and is used for discharging gas. The high-temperature gas safety valve with pressure relief protection is provided with a pressure relief pipe and a multistage pressure relief mechanism, a one-way gas inlet
assembly is used for guiding gas to enter step by step, a middle pressure relief
assembly is used for buffering and decompressing, and a one-way gas outlet
assembly is used for stably discharging, so that
scalding hazards are further avoided; the heat-resistant sealing piece on the outer side of the disc, the synchronous linkage design of the opening mechanism and the elastic buffering effect of the buffering mechanism ensure that the valve is sensitive in action under
high pressure, and the risk of jamming or failure is reduced.
