A brief introduction about the safety valve lever hammer

Hammer safety valve lever hammer and using leverage to balance the role of the force on the Gas Grill Control Valve. According to the principle of leverage it can use smaller mass weight by increasing the leverage effect of a larger force, and by moving the position of the weight (or mass conversion hammer) to adjust the safety valve opening pressure.
Simple lever hammer safety valve structure, adjust easily and more accurately, the applied load will not increase the valve flap and a larger increase for higher temperature of the occasion, it was more commonly used in the past, especially It is used in high temperature boiler and pressure vessel. But hammer lever thermostatic mixing valves structure is relatively bulky, easy loading mechanism vibration, and often due to vibration leakage; lower its back seat pressure, not easy to close after opening and holding tight.
