Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices, in particular to an intelligent constant-pressure water-supply exhaust device. Background Art

[0002] The water circulation system of the traditional heating system is based on the physical principles of heat convection and heat conduction. Through the circulation action of the water pump, water circulates in the system, thereby transferring heat to each room to achieve the purpose of increasing the indoor temperature. There is a large amount of gas in the water circulation system of the traditional heating system. These gases are prone to gas blockage, which causes obstruction of the circulation of water in part or the entire system, resulting in insufficient water flow in the system, and ultimately causing the indoor temperature to fail to reach the expected level. The oxygen contained in the air accelerates the oxidation corrosion of metal parts such as pipes and radiators, which need to be discharged in time when there is a lot of gas. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 The utility model provides a technical solution: an intelligent constant pressure water replenishment and exhaust device, comprising: a water tank 2, a connecting side pipe 3, a detection gas cylinder 4, a piston 5, an adjusting slide plate 8, a supporting inner frame 6 and an exhaust pipe 16. The connecting side pipe 3 is fixedly connected to one side of the water tank 2; the detection gas cylinder 4 is fixedly connected to one end of the connecting side pipe 3; the piston 5 is slidably arranged inside the detection gas cylinder 4; the adjusting slide plate 8 is slidably arranged inside the detection gas cylinder 4, and a No. 2 switch 12 cooperating with the piston 5 is installed on one side of the adjusting slide plate 8; the supporting inner frame 6 is fixedly connected to the inner side of the detection gas cylinder 4, and a No. 1 switch 7 cooperating with the piston 5 is installed on one side of the supporting inner frame 6; the exhaust pipe 16 is installed on the top of the water tank 2.

[0027] It can be understood that the utility model uses the circulating water pipeline body 13 as part of the pipeline of the water circulation system, and the No. 1 connecting pipe 14 and the No. 2 connecting pipe 15 are connected to the water tank 2. The gas in the circulating water will escape and gather in the water tank 2, causing the air pressure in the water tank 2 to gradually increase. The air pressure in the water tank 2 increases, and the air pressure enters the detection cylinder 4 through the connecting side pipe 3, pushing the piston 5 in the detection cylinder 4 outward, and the piston 5 moves in the detection cylinder 4. One side of the piston 5 pushes the No. 2 switch 12 on the side of the adjusting slide plate 8. At this time, the solenoid valve 17 is opened, and the air pump 18 exhausts the air. The tube 16 extracts the gas in the water tank 2. When the gas in the water tank 2 is extracted, the air pressure in the water tank 2 is reduced. At this time, the negative pressure in the water tank 2 drives the piston 5 in the detection air cylinder 4 to move, and the piston 5 moves toward the side of the connecting side tube 3. When the piston 5 touches the switch No. 1 7 on the side of the supporting inner frame 6, the solenoid valve 17 is closed, and the air pump 18 is closed to stop pumping air, so as to stabilize the air pressure in the water tank 2. The output end of the hydraulic cylinder 9 drives the adjusting slide plate 8 to move, and the adjusting slide plate 8 drives the No. 2 switch 12 to move, so as to adjust the limit value of the air pressure increase in the water tank 2, and adjust it according to different situations.

[0028] See also Figures 1 to 3 , and also includes a supporting base frame 1, which is fixedly connected to the bottom of the water tank 2. A circulating water pipeline body 13 is fixedly connected to the inside of the supporting base frame 1.

[0034] See also Figure 1 , a solenoid valve 17 is installed on the exhaust pipe 16.

[0035] It can be understood that the utility model performs gas sealing treatment in the water tank 2 by opening and closing the solenoid valve 17 on the exhaust pipe 16 .

[0036] See also Figures 1 to 3 A controller 20 is installed on the supporting frame 1 , and the No. 1 switch 7 , the hydraulic cylinder 9 , the No. 2 switch 12 , the solenoid valve 17 and the air pump 18 are all electrically connected to the controller 20 .

[0037] It can be understood that the utility model centrally controls the device through the controller 20, thereby improving the safety and work efficiency of the device.
