Boiler safety valve，safety valve

‌ boiler safety valve ‌ is an important safety device, mainly used to prevent the internal pressure of the boiler from exceeding the maximum allowable working pressure, so as to ensure the safe operation of the boiler. When the pressure in the boiler exceeds the set value, the safety valve will automatically open to release steam to reduce the pressure; The safety valve closes automatically when the pressure drops below the specified value ‌

Structural principle

The boiler safety valve is mainly composed of a seat, a disc and a pressurizing device. The valve seat is communicated with the pressure medium, and the valve disc is compressed on the valve seat by the pressure device. When the working pressure is greater than the pressure, the valve disc is opened and the medium pressure is relieved. When the pressure is greater than the medium pressure, the valve disc is pressed on the seat, and the regulating valve is closed. This design ensures automatic opening when the pressure exceeds the set point and automatic closing when the pressure drops ‌

species

Boiler safety valve can be divided into the following types according to the structure:

‌ deadweight ‌ : The use of a group of ring iron as a pressure device, heavy structure, inconvenient adjustment, often used in low pressure boilers.

‌ lever type ‌ : through the lever, weight and fulcrum balance pressure, simple structure, easy adjustment, suitable for high temperature occasions.

‌ spring type ‌ : The use of spring pressure, compact structure, sensitive action, suitable for mobile boiler, but the spring is affected by high temperature.

‌ impulse type ‌ (pilot operated or pulsed) : the main valve is driven by the auxiliary valve pulse action, suitable for large caliber and high pressure large capacity boiler ‌

‌ The application scenario of boiler safety valve ‌ mainly includes the following aspects:

‌ electric power industry ‌ : in the process of electric power production, the boiler is the core equipment for generating steam. The application of boiler safety valve ensures the safe operation of the boiler under high pressure and high temperature, and prevents accidents caused by overpressure ‌

‌ Chemical industry ‌ : Many chemical production processes need to be carried out under high temperature and pressure environment. Boiler safety valve can effectively prevent equipment overpressure, ensure production safety ‌

‌ heating system ‌ : in the city central heating system, the boiler is the main heat source equipment. The application of the safety valve ensures the stable operation of the heating system and avoids the supply shutdown accident caused by the boiler overpressure ‌

‌ The working principle of the boiler safety valve ‌ is based on the principle of pressure balance. When the pressure inside the boiler reaches or exceeds the preset value, the safety valve will automatically open to release excess steam or gas to reduce the pressure inside the boiler. Once the pressure has returned to the normal range, the safety valve will automatically close, ensuring that the boiler continues to operate safely
