Description

Technical Field

[0001] This utility model relates to the field of HVAC water supply and drainage pipe technology, and in particular to a seepage prevention device for HVAC water supply and drainage pipes. Background Technology

[0002] In modern building engineering, the seepage prevention performance of HVAC water supply and drainage piping systems is a key factor in ensuring the safety and service life of building structures. With the continuous development of building technology, traditional pipe seepage prevention methods can no longer fully meet the increasingly stringent engineering quality requirements. Traditional seepage prevention measures usually have many defects such as poor sealing performance, insufficient durability, and complex construction.

[0003] In existing anti-seepage devices on the market, seepage prevention is achieved through the connection method of sealant or sealing ring. However, due to the rapid aging of the sealant and the deformation of the sealing material, the sealing effect decreases, resulting in a decline in the anti-seepage effect. Furthermore, the pipeline is directly exposed to the external environment and is susceptible to corrosion by chemical media, which accelerates the degradation of the pipeline material.

The ball is movably connected to the spring. A control pipe is slidably connected to one side of the inner surface of the seepage prevention pipe, and a connecting shell is slidably connected to one side of the outer surface of the seepage prevention pipe.

Example

[0024] like Figure 1-5 As shown, a seepage prevention device for HVAC water supply and drainage pipes includes a connecting pipe 1, a seepage prevention pipe 2, and a protective component 3. The seepage prevention pipe 2 is threadedly connected to the connecting pipe 1. A spring 9 is fixedly connected to one side of the inner surface of the seepage prevention pipe 2, and a ball 4 is movable on one side of the inner wall of the seepage prevention pipe 2.

[0025] In this embodiment, the ball 4 is movably connected to the spring 9, the control tube 5 is slidably connected to one side of the inner surface of the seepage-proof pipe 2, and the connecting shell 6 is slidably connected to one side of the outer surface of the seepage-proof pipe 2. The connecting shell 6 is threadedly connected to the seepage-proof pipe 2.

[0026] In practical use, the user inspects the connecting pipe 1. After the inspection is completed, the user picks up the anti-seepage pipe 2 and connects it tightly to the connecting pipe 1 through the threaded connection. At the same time, the user closes the anti-seepage pipe 2 on the other side. Through the force of the spring 9, after the anti-seepage pipes 2 on both sides are closed, the control pipe 5 and the two spheres 4 on both sides are opened to allow water to flow. At the same time, the user slides the connecting shell 6 and connects it to the anti-seepage pipe 2 through the threaded connection to achieve the purpose of sealing the connection. This can also compensate for slight displacement and deformation of the pipe, maintain the stability of the connection, and facilitate maintenance, disassembly and replacement.

[0027] In this embodiment, a groove is provided on one side of the inner surface of the protective member 3, and a protective strip 7 is fixedly connected to one side of the outer surface of the protective member 3.

[0028] In practical use, the grooves allow the protective component 3 to reduce material rigidity, increase the deformation adaptability of the pipeline system, and reduce the risk of breakage during bending.

[0029] In this embodiment, the material of the protective strip 7 is special nitrile rubber.

[0030] In practical use, the protective strip 7 is made of special nitrile rubber, which has excellent oil resistance, resistance to corrosion from various chemical media, and acid and alkali resistance, thereby protecting the connecting pipe 1 from the impact of the external environment and achieving the purpose of protection.

[0031] In this embodiment, one side of the outer surface of the protective strip 7 is coated with a solvent-free epoxy coating.

[0032] In practical applications, by applying a solvent-free epoxy coating to the surface, the pipe surface can be effectively protected from corrosion and erosion for a long time, while also having the characteristic of being resistant to high and low temperature changes.

[0033] In this embodiment, a fastening screw 8 is threaded onto one side of the outer surface of the protective component 3.

[0034] In practical use, users can tighten the fastening screws 8 to enhance the connection strength, fix the various components of the pipeline system, and prevent the parts from loosening or falling off.

[0035] In this embodiment, there are two seepage-proof pipes 2, which can be closed to each other.

[0036] In practical use, the components can be closed to form a sealed ring structure, thereby enhancing the overall sealing performance.

[0037] In this embodiment, a ball 4 is movable on one side of the inner wall of the seepage-proof pipe 2. The ball 4 is movably connected to the spring 9. A control pipe 5 is slidably connected to one side of the inner surface of the seepage-proof pipe 2. The control pipe 5 can push the ball 4 to move.

[0038] In practical use, by setting up the ball 4, the ball 4 can actively adjust the sealing position according to the pressure change in the pipeline as water flows through it. At the same time, the control pipe 5 can precisely regulate the water flow to achieve the purpose of flow regulation.

[0039] In this embodiment, the material of the seepage prevention pipe 2 is a nickel-based alloy.

[0040] In practical use, the material of the seepage prevention pipe 2 is a nickel-based alloy, which achieves extremely high resistance to chemical media corrosion, resists corrosion from various acids, alkalis, salts, etc., and is suitable for complex corrosive environments.

[0041] Working Principle: During use, the user inspects the connecting pipe 1. After inspection, the user picks up the anti-seepage pipe 2 and connects it tightly to the connecting pipe 1 via a threaded connection. Simultaneously, the user closes the anti-seepage pipe 2 on the other side. Through the force of spring 9, after the two anti-seepage pipes 2 are closed, the control pipe 5 and the two spheres 4 on both sides allow water flow. At the same time, the user slides the connecting shell 6 and connects it to the anti-seepage pipe 2 via a threaded connection to achieve a sealed connection. This also compensates for slight displacement and deformation of the pipe, maintains the stability of the connection, and facilitates maintenance, disassembly, and replacement. The user bends the protective part 3 around the connecting pipe 1 through the groove. The user fixes the protective part 3 in place by tightening the fastening screw 8 to prevent it from falling off. By applying a solvent-free epoxy coating to the surface, the pipe surface is effectively protected from corrosion and erosion for a long time. It also has the characteristics of resistance to high and low temperature changes. The protective strip 7 is made of special nitrile rubber, which has excellent oil resistance, resistance to corrosion from various chemical media, and acid and alkali resistance, thus protecting the connecting pipe 1 from the impact of the external environment. This completes the installation of the anti-seepage device for HVAC water supply and drainage pipes.
