The operating philosophy: sincere, to the letter, innovation, refinement management strategy: people-oriented cast steel valves, fine management quality policy: to do, we should do our best brand objectives: to build national industry brands, world brand, a hundred years brand Shandong Everbright valve specializing in the production valve manufacturers, welcomed the new and old customers to order our products! Safety valve inlet and outlet piping (1) safety valve and the boiler or pressure vessel connection between the pipe and fittings through-hole, its cross-sectional area of ??not less than the cross-sectional area of ??the valve imported; if several valves share one inlet pipe, the import and flow area not less than the safety valve of the pipe cross-sectional area of ??the imports. (2) using a spring-loaded safety valve threaded connection, to connect with the short threaded pipe, while the short pipe and simplified, philatelic box to use welded connections. Safety valve to be fitted with a discharge pipe. Discharge pipe to avoid twists and sharp turns to minimize drag. Discharge tube through a safe place to stainless steel valves, and have sufficient flow area to ensure the exhaust flow. For the safety valve can interact to produce a chemical reaction, can not share a discharge pipe; when the valve is mounted on the corrosive, flammable gas equipment, should also take anti-corrosion or anti-fire explosion measures emissions; when installed security valve equipment for toxic media, and the vapor density of the medium is greater than the density of air, from the media and steam safety valves discharged to be introduced into a closed system, and recovering from a closed system into production use.
