Description

Technical Field

[0001] The utility model relates to the technical field of pressure control, in particular to a pressure control device for a boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] In order to facilitate and safely use the boiler, a pressure control device is needed to control and adjust the pressure inside the boiler. For example, the Chinese utility model patent with the announcement number CN218095880U discloses a pressure control device for a boiler, which includes a boiler body, a shell is fixedly connected to the inside of the boiler body, and the upper surface of the shell extends to the outside of the boiler body and is fixedly connected to an exhaust chamber, and a pressure regulating mechanism is installed inside the shell. The pressure regulating mechanism includes a motor, a screw rod, a nut, a pressure plate and a spring. The motor is fixedly connected to the upper surface of the shell, the screw rod is fixedly connected to the output end of the motor, the nut is movably connected to the surface of the screw rod, the pressure plate is fixedly connected to the surface of the nut, and the spring is fixedly connected to the lower surface of the pressure plate.

[0039] The working principle of the above embodiment is:

[0040] When the air pressure inside the boiler body 3 is too high, the gas will enter the interior of the connecting pipe 901 through the vent pipe 8. Since the air pressure inside the boiler body 3 is greater than the air pressure inside the sealed tank 903, the gas inside the boiler body 3 will push the push plate 906, the push rod 905 and the push block 904 to move, so that the push plate 906 moves to the top of the exhaust pipe 902, thereby connecting the exhaust pipe 902 with the connecting pipe 901. At this time, the gas inside the boiler body 3 will move to the outside of the boiler body 3 through the exhaust pipe 902. After the gas inside the boiler body 3 is discharged, the air pressure will be reduced, so that the air pressure inside the boiler body 3 is lower than that inside the sealed tank 903. The air pressure inside the sealed tank 903 is increased, so that the gas inside the sealed tank 903 pushes the push plate 906 to reset, thereby effectively controlling the air pressure inside the boiler body 3. By rotating the rotating rod 907, the rotating rod 907 can drive the adjusting block 908 to move due to the squeezing of the thread, thereby reducing the space inside the sealed tank 903, thereby effectively increasing the air pressure inside the sealed tank 903, so that the air pressure inside the boiler body 3 must be higher to push the push plate 906 to move, thereby effectively controlling the air pressure inside the boiler body 3. The overall structure is simple, effectively controls the air pressure inside the boiler body 3, and does not require a spring for reset, which effectively improves the overall durability.
