A tank safety valve which is used to seal off fluid or gas flow from the tank when an accident occurs. If the tank is damaged, such as by accidentally dropping the tank, it is most likely that the valve,Safety Valves which protrudes from the tank, (and is therefore most susceptible to damage) will allow the contents of the tank to leak. In order to prevent this type of leakage (from a broken valve),Water Pump Control Valves the body of the valve is provided with a weakened section. Internally, the valve is provided with a spring biased plunger or check valve plug which will be released when the weakened section is broken. The plunger and check valve plug will be moved upward by the force of a spring to block the opening which leads out of the tank.BALL VALVES Containers with gases or liquids typically have a main valve handle to control the dispensing of these products. Accidental breakage of the valve may result in dangerous or unhealthy release of the confined products. To ameliorate this possibility a safety back up valve has been proposed which is released when an internal breakable plunger releases a normally held spring biased check valve plug. The check valve's plug release acts to close the fluid flow from the main valve.A tank safety valve which is used to seal off fluid flow from the tank when an accident occurs.

The plunger or check valve plug will be moved upward by the force of a spring to block the opening which leads out of the tank. It is the primary object of the present invention to provide for an improved tank safety valve. Another object is to provide for an improved tank safety valve whose safety mechanism is actuated by damage to the valve.
