What are the three safety accessories of the boiler?

Boiler safety accessories mainly refer to pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve and other accessories. These accessories are very important for the safe operation of the boiler, especially the pressure gauge, water level gauge and safety valve, which are the basic accessories to ensure the safe operation of the boiler. Therefore, they are usually called the three safety accessories of industrial boilers. Knowing the three safety accessories of boiler is not enough, let's learn about the principle and function of each accessory.

Pressure gauges

The pressure gauge is used to measure the pressure in the boiler when the boiler is running. With the pressure gauge, the staff can operate the boiler correctly and ensure the safe operation of the boiler.

Users should pay attention that each boiler must be equipped with a pressure gauge directly connected to the steam space of the drum; The accuracy of boiler pressure gauges with different working pressures is different; Select the appropriate pressure gauge according to the working pressure of the boiler; The installation position shall be convenient for observation and purging, and shall be protected from radiant heat, freezing and vibration; The pressure gauge shall be composed of three-way cock and trap pipe below; The equipment, inspection and maintenance shall comply with the regulations of the national metrological department, and shall be calibrated at least once every six months. After calibration, it shall be sealed with lead.

Safety valve

The safety valve can automatically prevent the steam pressure of the boiler from exceeding the predetermined allowable range and ensure the safe operation of the boiler.

When the pressure in the boiler reaches the specified limit, the safety valve will automatically open, release steam and give an alarm, which will alert the operators and take measures. After the safety valve is opened, enough steam can be discharged to reduce the pressure in the boiler until it drops to a point lower than that when the valve is opened, and the valve will automatically close. In this way, the pressure of the boiler will be kept within the safe limit, so as not to cause an explosion accident.

Water level meter

The water level meter is an important safety device used to monitor the water level in the drum. Use the water level shown in the water level meter to indicate the water level in the drum. According to this, the firemen can operate correctly to ensure the safe operation of the boiler.

Users should pay attention to the fact that each boiler is equipped with at least two independent water meters to prevent the water level from being displayed in case of failure; Install a place convenient for observation; There should be clear signs indicating the height and low safe water level; Even the water pipe should be arranged horizontally to prevent the formation of false water level, etc.
