Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and more specifically, to a sealing device for air source heat pump jet enthalpy enhancement pipeline connection. Background Technology

[0002] An air source heat pump is a highly efficient device that utilizes heat energy from the air for heating or cooling. Its core principle is to "transfer" heat from a low-temperature environment to a high-temperature environment through a reverse Carnot cycle. The vapor injection enthalpy enhancement technology of air source heat pumps is an innovative technology optimized for low-temperature environments, primarily used to improve the heating efficiency and stability of the heat pump in cold climates.

[0003] In order to reduce heat loss and improve system efficiency, most existing air source heat pump vapor injection enthalpy enhancement pipelines are wrapped with an aluminum foil layer on the outside during use. This reduces the interference of the external environment on the pipeline temperature, helps maintain the stability of the vapor injection enthalpy enhancement cycle, and ensures reliable system operation. However, aluminum foil has low mechanical strength and is easily scratched or torn by sharp objects. At the same time, it has weak pressure and impact resistance. When used in the external environment for a long time, it is prone to oxidation and embrittlement, which leads to cracking. This results in poor protection of the pipeline and affects the overall sealing effect of the pipeline.

[0004] In view of this, we propose a sealing device for the connection of an air source heat pump jet enthalpy-enhancing pipeline. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A sealing device for connecting an air-source heat pump jet enthalpy-increasing pipeline includes a first semi-arc plate 1 and a second semi-arc plate 2. A first mounting plate 3 is fixedly installed on one side of both the first semi-arc plate 1 and the second semi-arc plate 2, and a second mounting plate 4 is fixedly installed on the other side of both the first semi-arc plate 1 and the second semi-arc plate 2. A connecting piece 5 is provided on the outer side of both the first mounting plate 3 and the second mounting plate 4. A fixing screw 6 is threaded through the outer side of the connecting piece 5. A positioning hole 7 for mating the fixing screw 6 is opened on the outer side of both the first mounting plate 3 and the second mounting plate 4. A protective cover 10 is fixedly installed on the outer side of the first mounting plate 3. A second sealing gasket 18 is fixedly installed on the inner side of both the first semi-arc plate 1 and the second semi-arc plate 2.

[0029] refer to Figure 1 , Figure 5 The second sealing gasket 18 has a certain elasticity. When the first semi-arc plate 1 and the second semi-arc plate 2 are installed on the outside of the pipeline, the second sealing gasket 18 will be squeezed. At the same time, by moving the connecting piece 5 and tightening the positioning screw 6, the first semi-arc plate 1 and the second semi-arc plate 2 can be quickly fixed together. Since the pipeline is in a fixed state, the protective cover 10 can fit against the outside of the jet enthalpy enhancement equipment, ensuring the overall installation stability.

[0030] Specifically, a T-shaped block 8 is fixedly installed on the outer side of the connecting piece 5, and a T-shaped groove 9 for engaging the T-shaped block 8 is opened on the outer side of the first mounting plate 3 and the second mounting plate 4.

[0031] refer to Figure 5 When the connecting piece 5 is moved, it can drive the T-block 8 to slide within the T-groove 9. When the connecting piece 5 is moved so that the positioning screw 6 aligns with the positioning hole 7, the T-block 8 abuts against the inner wall of the T-groove 9, ensuring the connection stability between the first semi-arc plate 1 and the second semi-arc plate 2.

[0032] Furthermore, a first sealing block 11 is fixedly installed on both sides of one set of protective covers 10, and a first sealing groove 12 that engages with the first sealing block 11 is opened on both sides of another set of protective covers 10.

[0033] refer to Figure 3 , Figure 4 When the two sets of protective covers 10 are combined, the first sealing block 11 is inserted into the inner side of the first sealing groove 12, which can improve the connection sealing between the two sets of protective covers 10, and make the sealing effect at the connection between the pipeline and the jet enthalpy enhancement equipment better.

[0034] It is worth noting that a second sealing block 13 is fixedly installed on both sides of the first semi-arc plate 1, and a second sealing groove 14 is opened on both sides of the second semi-arc plate 2 to engage with the second sealing block 13.

[0035] refer to Figure 3 , Figure 4 When the first semi-arc plate 1 and the second semi-arc plate 2 are installed on the outside of the pipeline, the second sealing block 13 is inserted into the inside of the second sealing groove 14, which can improve the connection sealing between the first semi-arc plate 1 and the second semi-arc plate 2, and make the sealing effect of the pipeline better.

[0036] It is worth noting that a set of first mounting plates 3 and second mounting plates 4 are fixedly provided with limit blocks 15 on both sides, and another set of first mounting plates 3 and second mounting plates 4 are provided with limit grooves 16 for docking with limit blocks 15 on both sides.

[0037] refer to Figure 3 , Figure 4When the first semi-arc plate 1 and the second semi-arc plate 2 are installed on the outside of the pipeline, so that the two sets of first mounting plates 3 and the two sets of second mounting plates 4 are combined, the limiting block 15 is inserted into the inner side of the limiting groove 16, thereby limiting the two sets of first mounting plates 3 and the two sets of second mounting plates 4, further ensuring the connection stability between the first semi-arc plate 1 and the second semi-arc plate 2, thereby further ensuring the protective sealing effect of the pipeline.

[0038] In addition, a first sealing gasket 17 is fixedly installed on the outside of the protective cover 10.

[0039] refer to Figure 2 When the protective cover 10 covers the connection between the pipeline and the jet enthalpy enhancement device, the first sealing gasket 17 is attached to the outside of the jet enthalpy enhancement device, further improving the sealing effect at the connection between the pipeline and the jet enthalpy enhancement device.

[0040] Working principle: First, the first semi-arc plate 1 and the second semi-arc plate 2 are respectively attached to the outside of the pipeline, so that the protective cover 10 covers the pipeline connection end and is attached to the outside of the jet enthalpy enhancement device. Then, the connecting piece 5 is moved so that the connecting piece 5 connects the two sets of first mounting plates 3 and the two sets of second mounting plates 4 together. Finally, the fixing screw 6 is screwed into the positioning hole 7, so that the first mounting plate 3 and the second mounting plate 4 can be fixed together. At this time, the second sealing gasket 18 on the inner side of the first semi-arc plate 1 and the second semi-arc plate 2 squeezes the pipeline, which can better protect and seal the pipeline.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
