。 Q: analyze the relief valve leak comprised of answer: a, the relief valve seat or valve disc tightly closed surface damage cause tightly closed surface damage comprised might be because corrosive medium denudation and actuating the confrontation on the surface of the metal tightly closed; It is possible that the relief valve during the installation process into the Marine valve valve into the oral cavity chamber or tightly closed surface dirt and facilities installed in the relief valve inlet piping or facilities within the welding slag, rust and mixed in media in various solid things with the relief valve discharge when the flowing speed of high-speed medium tightly closed surface and cause scars. Installed b, relief valve inappropriate actuating inappropriate mainly refers to the relief valve out import a petition to receive and manage by warp are formed by the installation errors of load to alignment valve damage or variant actuating leakage. C, high temperature valve actuating used in high temperature medium or in the background of this high temperature relief valve installation, welding layer on surface of the valve seat or valve core tightly closed ring of likely initiation warp are heating expansion and spring stiffness after heated to soften, reduce pretightening and tightly closed than pressure drops and actuating leak. D, choose an appropriate chooses the relief valve opening pressure relief valve and facilities real role stress comes too close, because facilities office pressure flap area close to or more than the relief of confining pressure may also be actuating valve leakage. E, the relief valve dirt in tightly closed surface because the assembly is not appropriate to make closed surface dirt or facilities and a strict management of dirt in tightly closed surface level high will cause the valve closes lax and leak tight.
