Description

Technical Field

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

[0002] Central heating refers to a method of supplying heat required for production, heating and life in a city (town) or part of an area through a pipeline network using steam and hot water generated by a centralized heat source. Central heating requires the use of a pressurized device for pressurized heating during the heating process.

[0003] For the central heating boosting devices on the market, the boosting pumps of most boosting devices need to be disassembled and maintained regularly during long-term use in order to ensure that the relay boosting pumps can provide normal pressure. However, in the existing technology, it is rather troublesome for the staff to disassemble the relay boosting pumps, which not only takes up more time of the staff, but also delays the work efficiency of the staff and is inconvenient for people to use. For this reason, we provide a central heating boosting device to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a centralized heating pressurizing device, which has the advantages of enhancing the practicality of the centralized heating pressurizing device and solving the problem that the centralized heating pressurizing device needs to be improved.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a centralized heating pressurizing device, comprising a heating tank, wherein a pressurizing structure is provided at the upper end of the heating tank.

[0006] The pressurizing structure includes a pressurizing box, a delivery pipe, a check valve, a boosting pump, a connecting pipe, a limit plate, a support plate, a telescopic spring and a sliding block. The pressurizing box is fixedly connected to the upper end of the heating tank, the delivery pipe passes through the pressurizing box and is connected to the upper end of the heating tank, the check valve is arranged on the delivery pipe, the sliding block is fixedly connected to the lower end of the boosting pump, the sliding block slides on the support plate, the telescopic spring is fixedly connected between the pressurizing box and the support plate, the limit plate is fixedly connected to the inner side wall of the pressurizing box, and the connecting pipe is connected to the lower end of the boosting pump.

[0007] A circular hole is provided inside the limiting plate, and the delivery pipe passes through the limiting plate through the circular hole.

[0008] It should be noted that the support plate and the telescopic spring can assist the booster pump in being disassembled and assembled with the delivery pipe more stably.

[0009] It is understandable that when the booster pump on the centralized heating pressure device needs to be removed for maintenance, the booster pump is rotated. At this time, the booster pump slides in the support plate through the sliding block. When the booster pump rotates with the connecting pipe, the connecting pipe will gradually separate from the delivery pipe. When the booster pump and the connecting pipe are lifted, the support plate will be lifted together with the telescopic spring until the connecting pipe is disconnected from the delivery pipe. The booster pump and the connecting pipe can be pulled out of the support plate through the sliding block to complete the disassembly. The installation principle of the booster pump in the pressure box can be reversed through the above working principle.

[0010] Furthermore, the left side of the heating tank is connected to a heating pipe, and the number of the heating pipes is three.

[0011] Furthermore, a solenoid valve is provided on the heating pipe, and a pressure gauge is provided on the heating pipe near the solenoid valve.

[0012] Among them, the three heating pipes have the same structure.

[0013] It should be noted that the solenoid valve is an existing mature technology. It is a valve that uses the electromagnetic principle to control the flow of fluids (such as water, oil, gas, etc.). It consists of an electromagnetic coil and a valve body. When the electromagnetic coil is energized, it generates a magnetic field, driving the valve core to move, thereby opening or closing the valve and controlling the flow of the fluid.

[0014] It can be understood that a pressure gauge is an instrument used to measure and display pressure. It can indicate the pressure value in the system or equipment so that operators or automated systems can make adjustments and controls accordingly. Pressure gauges are widely used in various industrial and laboratory environments and are essential to ensuring the normal operation of equipment and system safety.

[0015] Furthermore, the pressurized box is provided with heat dissipation holes, and the number of the heat dissipation holes is several.

[0016] Furthermore, a thread groove is provided inside the delivery pipe, and the connecting pipe is threadedly connected to the delivery pipe through the thread groove.

[0017] Furthermore, a sliding groove is provided inside the support plate, and the sliding block slides inside the support plate through the sliding groove.

[0018] A through hole is provided inside the support plate near the sliding groove.

[0019] It should be noted that the connecting pipe passes through the supporting plate through the through hole.

[0020] Furthermore, a movable groove is provided in the pressurizing box, and the support plate slides in the pressurizing box through the movable groove.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The centralized heating pressurizing device has a disassembly and assembly structure provided on the heating tank, which makes it easy for workers to quickly disassemble and assemble the booster pump from the pressurizing box, thereby making it easy for workers to disassemble the booster pump for regular maintenance, thereby enhancing the practicality of the centralized heating pressurizing device and other advantages.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 4 A centralized heating pressurizing device in this embodiment includes a heating tank 1, and a pressurizing structure is provided on the upper end of the heating tank 1.

[0030] The pressurization structure includes a pressurization box 5, a delivery pipe 6, a check valve 7, a booster pump 8, a connecting pipe 9, a limit plate 10, a support plate 11, a telescopic spring 12 and a sliding block 13. The pressurization box 5 is fixedly connected to the upper end of the heating tank 1, the delivery pipe 6 passes through the pressurization box 5 and is connected to the upper end of the heating tank 1, the check valve 7 is arranged on the delivery pipe 6, the sliding block 13 is fixedly connected to the lower end of the booster pump 8, the sliding block 13 slides on the support plate 11, the telescopic spring 12 is fixedly connected between the pressurization box 5 and the support plate 11, the limit plate 10 is fixedly connected to the inner wall of the pressurization box 5, and the connecting pipe 9 is connected to the lower end of the booster pump 8.

[0031] A circular hole is opened inside the limiting plate 10 , and the delivery pipe 6 passes through the limiting plate 10 through the circular hole.

[0032] It should be noted that the support plate 11 cooperates with the telescopic spring 12 to assist the booster pump 8 in being assembled and disassembled from the delivery pipe 6 more stably.

[0033] It can be understood that when the booster pump 8 on the centralized heating pressure device needs to be removed for maintenance, the booster pump 8 is rotated. At this time, the booster pump 8 slides in the support plate 11 through the sliding block 13. When the booster pump 8 rotates in conjunction with the connecting pipe 9, the connecting pipe 9 will gradually separate from the delivery pipe 6. When the booster pump 8 and the connecting pipe 9 are lifted, the support plate 11 will be lifted together with the telescopic spring 12 until the connecting pipe 9 is disconnected from the delivery pipe 6. The booster pump 8 and the connecting pipe 9 are pulled out of the support plate 11 through the sliding block 13 to complete the disassembly. The installation principle of the booster pump 8 in the pressurized box 5 can be reversed through the above working principle.

[0034] In this embodiment, the left side of the heating tank 1 is connected to a heating pipe 2 , and the number of the heating pipes 2 is three.

[0035] In this embodiment, a solenoid valve 3 is provided on the heating pipe 2 , and a pressure gauge 4 is provided on the heating pipe 2 near the solenoid valve 3 .

[0036] Among them, the three heating pipes 3 have the same structure.

[0037] It should be noted that the solenoid valve 3 belongs to the existing mature technology. The solenoid valve 3 is a valve that uses the electromagnetic principle to control the flow of fluid (such as water, oil, gas, etc.). It consists of an electromagnetic coil and a valve body. When the electromagnetic coil is energized, a magnetic field is generated to drive the valve core to move, thereby opening or closing the valve and controlling the flow of the fluid.

[0038] It can be understood that the pressure gauge 4 is an instrument used to measure and display pressure. It can indicate the pressure value in the system or equipment so that the operator or the automation system can adjust and control it accordingly. The pressure gauge 4 is widely used in various industrial and laboratory environments and is crucial to ensuring the normal operation of the equipment and the safety of the system.

[0039] In this embodiment, the pressurizing box 5 is provided with a plurality of heat dissipation holes.

[0040] In this embodiment, a thread groove is provided inside the delivery pipe 6 , and the connecting pipe 9 is threadedly connected to the delivery pipe 6 via the thread groove.

[0041] In this embodiment, a sliding groove is defined inside the support plate 11 , and the sliding block 13 slides inside the support plate 11 through the sliding groove.

[0042] A through hole is formed inside the support plate 11 near the sliding groove.

[0043] It should be noted that the connecting pipe 9 passes through the supporting plate 11 through the through hole.

[0044] In this embodiment, a movable groove is opened in the pressurizing box 5, and the support plate 11 slides in the pressurizing box 5 through the movable groove.

[0045] The working principle of the above embodiment is:

[0046] When the booster pump 8 on the centralized heating pressure device needs to be removed for maintenance, the booster pump 8 is rotated. At this time, the booster pump 8 slides in the support plate 11 through the sliding block 13. When the booster pump 8 rotates in conjunction with the connecting pipe 9, the connecting pipe 9 will gradually separate from the delivery pipe 6. When the booster pump 8 and the connecting pipe 9 are lifted, the support plate 11 will be lifted together with the telescopic spring 12 until the connecting pipe 9 is disconnected from the delivery pipe 6. The booster pump 8 and the connecting pipe 9 are pulled out of the support plate 11 through the sliding block 13 to complete the disassembly. The installation principle of the booster pump 8 in the pressurized box 5 can be reversed through the above working principle.
