Abstract
The utility model relates to a three-insurance self-closing valve used for acting on a flashboard and associated mechanism thereof to control a switch by a magnetic field and a manual switch in parallel. Hidden danger in safety frequently exists in a past gas valve, and for example, the pressure of a medium pressure pipe network directly enters users' homes, very large dangers are brought for users; because people also frequently forgets to close down a valve after the air supply is suddenly interrupted, and the fuel gas is directly exhausted into rooms, after the air supply is restored, the accidents, such as fire, explosion, gas poisoning, etc., are easily caused. The structure of the utility model is that an upper and a lower two sets of magnets are arranged in a valve body, a rubber flashboard and a ball valve connected by a vertical axial draw rod and a rubber rod are arranged at the middle of the valve body, the ball valve extends into a conical gas inlet, and the ball valve is driven by the flashboard up and down along the change of gas pressure; thereby, the self-closing function is reached. After the gas pressure gets right, the draw rod extended out of the valve body can be pushed or lifted by manual work, the valve is restored in an opening state and the valve can be forcibly closed by the manual work. A manual corner valve can be manually opened or closed according to people's requirements, so ternary insurance is achieved.
