Actuating disc breaking is comprised of: medium pressure before and after the check Industrial Valves is close to equilibrium and mutual 'see-saw' situation, disc and seat often play gently, some brittle material ( Such as cast iron, brass, etc. ) The disc was broken. Fix tightly closed surface and cleaning impurity, can avoid reverse flow. 。 Q: non-return valve or check valve of the common faults and prevent a: common faults are: (1) the disc for Marine valve broken; (2) the medium flow. Medium counter-current comprised: (1) tightly closed surface damage; (2) the clip into the impurities. Prevention method is right and use the disc check valves for ductile materials. Above narration about common fault and prevention measures, only a revelation of the utility, practice, also will encounter other fault, to do active flexibility to prevent the happening of the valve failure, the most fundamental one is to know clearly the structure, material and movement theory.
