Second, the principle Form of pressure relief valves are sealed, after the jump start the disc out of the pipeline through the media then discharged, with the rotation adjustment screw to adjust the amount of compression spring, the spring force transmitted through the stem valve, when the media more than the spring force , the force rises valve, discharge excess medium, when the device is back to normal when the pressure within the medium, under the action of the disc itself off in the spring. Third, the structure description: Pressure relief valve seal is produced by the compression spring force, the valve flap close contacts with the valve seat sealing surface, play a role in sealing. Valve and valve seat sealing surface is made of iron-based alloy cladding. Sets should not be driven by the dead body. Stem surface after nitrogen treatment, with good resistance to abrasion and corrosion resistance. Constitute a small shaft and crank the handle manually institutions. Turn the power to run the agency should periodically check valve action situation. Plug in the pressure relief valve positioning guide condom adjusted, the screw positioning sleeve into the side of the hole, to prevent the positioning sleeve rotation. Pressure relief valve
