Description

Technical Field

[0001] This utility model relates to the field of HVAC condensate leak prevention technology, specifically to a HVAC condensate leak prevention device for building engineering. Background Technology

[0002] In the field of building engineering, heating, ventilation, and air conditioning (HVAC) systems are important facilities for ensuring indoor environmental comfort. If the condensate water generated during their operation is not handled properly, leakage problems can easily occur, which can have adverse effects on the building structure and indoor environment.

[0003] Currently, the traditional connection between HVAC condensate pipes and outlet pipes is not well-sealed, usually relying on simple fittings or sealing materials. Over long-term use, factors such as temperature changes and water flow impact can cause gaps to appear at the seal, leading to condensate leakage. Furthermore, during actual installation and use, displacement can easily occur between the condensate pipe and the protective components, and between the protective components themselves, further increasing the risk of condensate leakage.

[0004] In summary, it is urgent to develop a condensate leak prevention device for building engineering HVAC systems that can effectively solve the above problems. Therefore, this utility model proposes a condensate leak prevention device for building engineering HVAC systems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a leak-proof device for HVAC condensate in building engineering, comprising:

[0008] A condensate drain pipe is fitted over the left protective component. A sealing ring is provided on the end face of the left protective component, and the end face of the sealing ring is inserted into the mounting groove. The mounting groove is located on the end face of the right protective component. The right protective component is fitted over the outlet pipe. An integrally formed positioning rod is provided at the end of the right protective component, and the outside of the positioning rod is inserted into the limiting port. The limiting port is located on the outside of the left protective component.

[0009] According to some embodiments of the present invention, the outer surface of the left protective member is provided with an integrally formed convex ring, and a limiting port is opened on the outer surface of the convex ring of the left protective member. A circular through hole is opened on the end face of the limiting port. The limiting ports are arranged in four groups, and the four groups of limiting ports are arranged in a circular array along the central axis of the right protective member.

[0010] According to some embodiments of the present invention, the end of the positioning rod is provided with an integrally formed hemispherical body, and the positioning rod is configured in four groups, and the four groups of positioning rods are arranged in a circular array along the central axis of the right protective member.

[0011] According to some embodiments of the present invention, the left protective member has a stabilizing through hole inside, a limiting guide rod is movably sleeved in the stabilizing through hole, a movable rod is integrally formed at the end of the limiting guide rod, the movable rod is movably disposed inside the left protective member, the end of the movable rod is fixed to the left end of the sealing gasket, and a return spring is sleeved on the outside of the movable rod, the return spring being located at the left end of the sealing gasket.

[0012] According to some embodiments of the present invention, the right end face of the sealing gasket abuts against the end of the extrusion rod, and the end of the support rod of the extrusion rod is integrally formed and disposed inside the right protective member.

[0013] According to some embodiments of the present invention, the right protective member is provided with an integrally formed convex ring on its exterior, and a compression spring is sleeved on the exterior of the right protective member. The compression spring is located on the right side of the protective ring, and the inner ring of the protective ring is movably sleeved on the exterior of the right protective member.

[0014] According to some embodiments of this utility model, the cross-section of the sealing gasket is frustum-shaped, and the material used for the sealing gasket is rubber.

[0015] According to some embodiments of the present invention, the left end of the extrusion rod is provided with an integrally formed hemispherical body, the right end of the extrusion rod is provided with an integrally formed support shaft, and the end of the support shaft of the extrusion rod is located inside the right protective member.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. By inserting the end face of the sealing ring into the mounting groove, the connection between the condensate pipe and the right protective component is sealed, preventing leakage of condensate flowing between the condensate pipe and the outlet pipe. When the outside of the positioning rod is inserted into the limiting port, it locks the condensate pipe and the right protective component. When the positioning rod is inserted into the limiting port, the connection between the left and right protective components is more secure, preventing water leakage when the sealing ring between the left and right protective components is sealed. When the positioning rod is inserted into the limiting port and the outlet pipe is turned, the hemispherical part at the end of the positioning rod engages with the outer convex ring of the left protective component, thus ensuring a secure and locked connection between the left and right protective components.

[0019] Second, by installing a return spring on the outside of the moving rod, the spring force of the return spring causes the sealing gasket to move to the right inside the left protective part. Therefore, the condensate in the left protective part will not flow inside. When the sealing gasket is pressed to the left inside the left protective part, the condensate in the left protective part flows to the right protective part and is then discharged through the water outlet pipe. The spring force of the compression spring pushes the protective ring to the left outside the right protective part. Therefore, the inner ring of the protective ring is fitted on the outside of the left protective part, which provides a protective effect for the sealing ring between the left and right protective parts.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] See attached document Figure 1-7 A condensate leak-proof device for building construction, comprising:

[0032] A condensate pipe 1 is fitted outside the left protective component 4. A sealing ring 8 is provided on the end face of the left protective component 4, and the end face of the sealing ring 8 is inserted into the mounting groove 9. The mounting groove 9 is opened on the end face of the right protective component 10. The outside of the right protective component 10 is fitted inside the outlet pipe 14. An integrally formed positioning rod 16 is provided at the end of the right protective component 10, and the outside of the positioning rod 16 is inserted into the limiting port 15. The limiting port 15 is opened outside the left protective component 4. By setting a sealing ring 8 on the outside of the condensate pipe 1 and inserting the end face of the sealing ring 8 into the mounting groove 9, the connection between the condensate pipe 1 and the right protective component 10 is sealed to prevent leakage of condensate flowing between the condensate pipe 1 and the outlet pipe 14. When the outside of the positioning rod 16 is inserted into the limiting port 15, it achieves a positioning and locking effect between the condensate pipe 1 and the right protective component 10.

[0033] According to some embodiments of this utility model, an integrally formed convex ring is provided on the outside of the left protective member 4. A limiting port 15 is provided on the outside of the convex ring of the left protective member 4. A circular through hole is provided on the end face of the limiting port 15. The limiting ports 15 are arranged in four groups, and the four groups of limiting ports 15 are arranged in a circular array along the central axis of the right protective member 10. By providing four groups of limiting ports 15 on the outside of the left protective member 4, when the positioning rod 16 is inserted into the limiting port 15, the connection between the left protective member 4 and the right protective member 10 is more stable, so as to prevent water leakage when the sealing ring 8 between the left protective member 4 and the right protective member 10 is sealed.

[0034] According to some embodiments of this utility model, the end of the positioning rod 16 is provided with an integrally formed hemispherical body. The positioning rod 16 is configured in four groups, and the four groups of positioning rods 16 are arranged in a circular array along the central axis of the right protective member 10. By providing an integrally formed hemispherical body at the end of the positioning rod 16, when the positioning rod 16 is inserted into the knob water outlet pipe 14 in the limiting port 15, the hemispherical body at the end of the positioning rod 16 is engaged with the outer convex ring of the left protective member 4, thereby enabling the connection between the left protective member 4 and the right protective member 10 to achieve a stable locking effect.

[0035] In the above technical solution, by inserting the end face of the sealing ring 8 into the mounting groove 9, the connection between the condensate pipe 1 and the right protective component 10 is sealed, preventing leakage of condensate flowing between the condensate pipe 1 and the outlet pipe 14. When the outside of the positioning rod 16 is inserted into the limiting port 15, it achieves a positioning and locking effect between the condensate pipe 1 and the right protective component 10. When the positioning rod 16 is inserted into the limiting port 15, the connection between the left protective component 4 and the right protective component 10 becomes more stable, preventing water leakage when the sealing ring 8 between the left protective component 4 and the right protective component 10 is sealed. When the positioning rod 16 is inserted into the limiting port 15 and the outlet pipe 14 is turned, the hemispherical part at the end of the positioning rod 16 is engaged with the outer convex ring of the left protective component 4, thereby achieving a stable locking effect between the left protective component 4 and the right protective component 10.

[0036] According to some embodiments of this utility model, a stabilizing through hole 2 is provided inside the left protective member 4. A limiting guide rod 5 is movably sleeved in the stabilizing through hole 2. A movable rod 3 is integrally formed at the end of the limiting guide rod 5. The movable rod 3 is movably disposed inside the left protective member 4. The end of the movable rod 3 is fixed to the left end of the sealing gasket 7. A return spring 6 is sleeved on the outside of the movable rod 3. The return spring 6 is located at the left end of the sealing gasket 7. By sleeved on the outside of the movable rod 3, the elastic force of the return spring 6 causes the sealing gasket 7 to move to the right inside the left protective member 4. Therefore, the condensate in the left protective member 4 will not flow inside. When the sealing gasket 7 is pressed to the left inside the left protective member 4, the condensate in the left protective member 4 flows to the right protective member 10 and is then discharged through the water outlet pipe 14.

[0037] According to some embodiments of this utility model, the right end face of the sealing gasket 7 abuts against the end of the extrusion rod 11. The end of the support rod of the extrusion rod 11 is integrally formed and disposed in the right protective member 10. By fixing the support rod of the extrusion rod 11 in the right protective member 10, when the left protective member 4 and the right protective member 10 are connected, the left end of the extrusion rod 11 abuts against the right end of the sealing gasket 7, so that the sealing gasket 7 moves in the condensate pipe 1, thus realizing the flow of condensate in the left protective member 4.

[0038] According to some embodiments of this utility model, an integrally formed convex ring is provided on the outside of the right protective member 10, and a compression spring 13 is sleeved on the outside of the right protective member 10. The compression spring 13 is located on the right side of the protective ring 12, and the inner ring of the protective ring 12 is movably sleeved on the outside of the right protective member 10. The compression spring 13 pushes the protective ring 12 to the left outside the right protective member 10, so the inner ring of the protective ring 12 is sleeved on the outside of the left protective member 4, which provides a protective effect for the sealing ring 8 between the left protective member 4 and the right protective member 10.

[0039] According to some embodiments of the present invention, the sealing gasket 7 has a frustum-shaped cross section and is made of rubber. By placing the sealing gasket 7 in a frustum-shaped configuration inside the left protective member 4, the sealing gasket 7 seals the condensate flowing through the left protective member 4 when the left protective member 4 and the right protective member 10 are separated.

[0040] According to some embodiments of the present invention, an integrally formed hemispherical body is provided at the left end of the extrusion rod 11, and an integrally formed support shaft is provided at the right end of the extrusion rod 11. The end of the support shaft of the extrusion rod 11 is located inside the right protective member 10. By providing an integrally formed hemispherical body at the left end of the extrusion rod 11, the resistance to condensate flow in the left protective member 4 and the right protective member 10 is reduced.

[0041] In the above technical solution, by sleeved with a return spring 6 on the outside of the moving rod 3, the elastic force of the return spring 6 causes the sealing gasket 7 to move to the right inside the left protective member 4. Therefore, the condensate in the left protective member 4 will not flow inside. When the sealing gasket 7 is pressed to the left inside the left protective member 4, the condensate in the left protective member 4 flows to the right protective member 10 and is then discharged through the water outlet pipe 14. The elastic force of the squeeze spring 13 pushes the protective ring 12 to the left outside the right protective member 10. Therefore, the inner ring of the protective ring 12 is sleeved on the outside of the left protective member 4, which provides a protective effect for the sealing ring 8 between the left protective member 4 and the right protective member 10.

[0042] Working principle: By inserting the end face of the sealing ring 8 into the mounting groove 9, the connection between the condensate pipe 1 and the right protective component 10 is sealed, preventing leakage of condensate flowing between the condensate pipe 1 and the outlet pipe 14. When the outside of the positioning rod 16 is inserted into the limiting port 15, it locks the connection between the condensate pipe 1 and the right protective component 10. When the positioning rod 16 is inserted into the limiting port 15, the connection between the left protective component 4 and the right protective component 10 is more secure, preventing water leakage when the sealing ring 8 between the left and right protective components 4 and 10 is sealed. When the positioning rod 16 is inserted into the limiting port 15 and the outlet pipe 14 is turned, the hemispherical part at the end of the positioning rod 16 engages with the left protective component 4. The outer convex ring of the left protective member 4 and the right protective member 10 can be securely locked. By sleeved on the outside of the moving rod 3, the spring force of the return spring 6 causes the sealing gasket 7 to move to the right inside the left protective member 4. Therefore, the condensate in the left protective member 4 will not flow inside. When the sealing gasket 7 is pressed to the left inside the left protective member 4, the condensate in the left protective member 4 flows to the right protective member 10 and is then discharged through the water outlet pipe 14. The spring force of the squeeze spring 13 pushes the protective ring 12 to the left outside the right protective member 10. Therefore, the inner ring of the protective ring 12 is sleeved on the outside of the left protective member 4, which provides a protective effect for the sealing ring 8 between the left protective member 4 and the right protective member 10.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
