Description

[0002] Boiler is a kind of energy conversion equipment, mainly for the chemical energy or other forms of heat energy in fuel is converted into heat energy, and then through the heating of water or other working medium, steam, hot water or other heat carrier is generated.

[0003] When the boiler pressure detection needs to be relieved, a safety valve is generally used. In the normal process, the safety valve is in a normally closed state, and the spring or other loading mechanism inside the safety valve exerts a certain mechanical load on the valve disc, so that the valve disc is tightly pressed on the valve seat to prevent medium leakage. After the safety valve is opened, the medium in the boiler is discharged through the discharge port of the safety valve, thereby reducing the pressure in the boiler. However, during the operation of the boiler, impurities and dirt in the water may deposit at the valve core of the safety valve, causing the valve core to stick, which affects the normal opening and closing of the safety valve. Regular steam and water discharge can flush the safety valve to prevent the valve core from sticking and ensure that the safety valve can act quickly and reliably when the pressure is too high. Today, steam and water discharge is usually performed manually. However, during the steam discharge process, high-temperature and high-pressure steam may be sprayed out, which may cause burns or other accidents if the operator does not take proper precautions.

The elastic mechanism is set on the top of the boiler body 1 through a transverse sliding mechanism and is used to drive the collision plate 5 to touch the opening and closing handle 6.

[0022] After the boiler has been in use for a period of time, water and steam need to be released from the inside of the boiler body 1 through the pressure relief valve 4. Releasing water and steam can stabilize the pressure inside the boiler body 1. At this time, the transverse sliding mechanism needs to be activated. The transverse sliding mechanism includes a transmission frame 7, a motor 8, a reciprocating screw 9, a screw nut 10, and a sliding assembly. The transmission frame 7 is fixedly connected to the top of the boiler body 1. The motor 8 is installed on the outer side wall of one side of the transmission frame 7. The reciprocating screw 9 is fixedly connected to the output end of the motor 8. The screw nut 10 is threadedly connected to the outer wall of the reciprocating screw 9. The sliding assembly is located at the end of the boiler body 1 away from the transmission frame 7. The transmission frame 7 and the fixed frame 11 are respectively located on both sides of the sealing cover 3. Start the motor 8 to drive the reciprocating screw 9 to rotate. At this time, the screw nut 10 threadedly connected to the reciprocating screw 9 will start to slide laterally. Then, through the cooperation of the screw nut 10 and the sliding assembly, the elastic mechanism is driven to slide to the side of the pressure relief valve 4.

[0023] The sliding assembly comprises a fixed frame 11, a light pole 12 and a sliding block 13, the fixed frame 11 is fixedly connected at the top of the furnace body 1 away from the transmission frame 7, the light pole 12 is fixedly connected between the inner side walls on both sides of the fixed frame 11, and the sliding block 13 is slidingly matched on the outer wall of the light pole 12; the elastic mechanism comprises a support rod 14, a support plate 15, a rebound groove 16 and a spring 17, the support rod 14 is fixedly connected at the top of the sliding block 13 and the lead screw nut 10, the support plate 15 is fixedly connected at the top of the two support rods 14, the rebound groove 16 is arranged at the top of the support plate 15, two springs 17 are fixedly connected in the rebound groove 16, and the other end of the spring 17 is fixedly connected with the collision plate 5; the support plate 15 is arranged below the opening and closing handle 6, and the support rod 14 fixedly connected with the lead screw nut 10 and the top of the sliding block 13 is arranged on the support plate 15, so that when the lead screw nut 10 is driven to slide transversely by the reciprocating lead screw 9, the sliding block 13 also slides transversely synchronously, at this time, the support plate 15 drives the collision plate 5 on the spring 17 to move close to the pressure relief valve 4, and then the collision plate 5 first touches the opening and closing handle 6, and since the end of the opening and closing handle 6 is not touched, the opening and closing handle 6 needs to be moved after the collision plate 5, the collision plate 5 after moving in the opposite direction drives the opening and closing handle 6 to move, so that the opening and closing handle 6 is opened, at this time, the steam and water can be discharged, and after the steam and water discharge is completed, the lead screw nut 10 and the sliding block 13 drive the collision plate 5 to move to the initial placement position, and during the movement, the collision plate 5 passes through the opening and closing handle 6 through the elastic deformation of the spring 17, and then the opening and closing handle 6 naturally returns to the original position to close the pressure relief valve 4.
