Today's Xiaobian takes "2 Tph Gas Fired Industrial Steam boiler" as an example. Let's take a brief look at the function of lever type safety valve for industrial boiler.
Function of lever type safety valve for industrial boiler
Industrial boiler lever type safety valve is divided into single lever type and parallel bar type. Because they act on the valve core through the heavy torque of the lever and the weight hammer, they are used to balance the steam (water) pressure, also known as the weight hammer safety valve. Stem (heavy hammer) safety valve is mainly composed of valve core, seat, lever, weight hammer, limiting device and so on.
By using the weight of the weight hammer, the valve core is pressed on the seat by lever, and the position of the weight hammer is moved to change the weight torque to adjust the opening pressure of the safety valve. When the boiler pressure exceeds the pressure of the weight hammer acting on the upper part of the valve core, the valve core is lifted out of the seat and the steam is discharged. To boiler pressure below heavy When the hammer acts on the pressure of the upper part of the valve core, the valve core falls down and the boiler stops exhaust steam.
The safety valve is simple in structure, convenient in adjustment and reliable in performance, so it is widely used in boilers. The general horizontal bar safety valve is suitable for low pressure boiler, and the parallel bar type safety valve is suitable for medium and high pressure boiler.
The above is based on my personal experience and 2 Tph Gas Fired Industrial Steam boiler For example, for everyone to do simple sharing, I hope to be useful to everyone
