Description

Technical Field

[0001] This utility model relates to the field of water pipe repair technology, and in particular to a rubber sealing device for water pipe repair. Background Technology

[0002] In modern urban water supply and industrial fluid transportation, the efficiency and sealing of water pipe maintenance work are directly related to the stability of public services and production safety.

[0003] Currently, most rubber sealing devices used for water pipe repair on the market employ a single sealing principle. For example, traditional annular rubber sleeves fill pipe gaps through radial compression deformation, or threaded connections rely solely on mechanical tightening force for sealing. However, such single sealing methods have significant limitations in actual working conditions: when faced with water flow impact, thermal expansion and contraction of pipes due to environmental temperature differences, and high-frequency vibrations caused by water pump operation, single sealing structures are prone to elastic fatigue, loosening, and displacement, leading to seal failure. Therefore, a rubber sealing device for water pipe repair has been proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a rubber sealing device for water pipe repair, which solves the problem mentioned in the background art that the rubber sealing devices for water pipe repair currently used in the market mostly adopt a single sealing principle. However, such a single sealing method has obvious limitations in actual working conditions: when faced with water flow impact, thermal expansion and contraction of pipes caused by environmental temperature differences, and high-frequency vibration caused by water pump operation, the single sealing structure is prone to elastic fatigue, loosening and displacement, which leads to sealing failure.

[0008] As a further embodiment of this utility model, the closed hemisphere is rotatably connected to the inside of the adjusting tube, and the surface of the rotating handle is provided with several anti-slip grooves, which serve to prevent slipping.

[0009] As a further embodiment of this utility model, a water pipe body is connected through one side of the external interface, and the external interface is inserted into the inside of the main pipe. The external interface serves as a connection and sealing device.

[0010] As a further embodiment of this utility model, the surface of the external interface is provided with a threaded hole, and one end of the external interface is inserted into the interior of the rubber sealing ring. The rubber sealing ring serves to achieve a sealing function.

[0014] (III) Beneficial Effects

[0015] This utility model provides a rubber sealing device for water pipe repair, which has the following beneficial effects:

[0016] 1. This rubber sealing device for water pipe repair, through the setting of a first sealing mechanism and a second sealing mechanism, allows the outer interface to be inserted into the main pipe during use. This ensures that the rubber sealing ring installed inside the main pipe fits tightly against the surface of the outer interface. The support spring installed inside the rubber sealing ring further enhances the sealing performance of the rubber sealing ring. Next, a sealing strip is wrapped around the threaded part of the outer interface. Then, the tapered tube on the surface of the main pipe is slid and rotated, so that the tapered tube is tightly fixed to the surface of the outer interface using the threaded structure, thereby achieving a double sealing effect. Compared with the traditional single sealing method, the sealing effect is better.

[0017] 2. This rubber sealing device for water pipe maintenance, with its flow regulating mechanism and pressure gauge, allows for segmented drainage of old pipes or pressure testing of newly installed pipes. By rotating the handle on the regulating pipe, the closed hemisphere at the bottom of the handle rotates inside the pipe, adjusting the water flow and pressure using the angle formed with the pipe wall. Combined with the pressure gauge installed on one side, it can accurately display the pressure value inside the pipe in real time, adjusting the pressure to a suitable range and preventing localized negative pressure caused by excessively fast drainage, which could lead to pipe collapse or loosening of joints.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a rubber sealing device for water pipe repair, including a main pipe 1 and a pressure gauge 6 installed on one side of the main pipe 1. A first sealing mechanism 2 is installed inside the main pipe 1. By setting the first sealing mechanism 2 and the second sealing mechanism 3, a double sealing effect is achieved. Compared with the traditional single sealing method, the sealing effect is better. The surface of the main pipe 1 is slidably connected to the second sealing mechanism 3. A regulating pipe 4 is connected through one side of the main pipe 1. A flow regulating mechanism 5 is installed on the surface of the regulating pipe 4. By setting the flow regulating mechanism 5 and the pressure gauge 6, the local negative pressure in the pipe caused by excessive drainage speed is avoided, which may lead to pipe collapse or loosening of the joint.

[0025] The first sealing mechanism 2 includes a rubber sealing ring 201 installed inside the main pipe 1, and a support spring 202 is installed inside the rubber sealing ring 201.

[0026] The second sealing mechanism 3 includes a tapered tube 301 that is slidably connected to the surface of the main pipe 1. The tapered tube 301 has an external interface 302 connected internally by threads, and a sealing strip 303 is wrapped around the surface of the external interface 302.

[0027] The flow regulating mechanism 5 includes a rotating handle 501 mounted on the surface of the regulating pipe 4, and a closed hemisphere 502 is fixedly connected to the bottom of the rotating handle 501.

[0028] The closed hemisphere 502 is rotatably connected to the inside of the regulating tube 4. The surface of the rotating handle 501 is provided with several anti-slip grooves, which play an anti-slip role.

[0029] One side of the external interface 302 is connected to the main body of the water pipe 10. The external interface 302 is inserted into the inside of the main pipe 1. The external interface 302 serves as a connection and sealing device.

[0030] The surface of the external interface 302 is provided with a threaded hole, and one end of the external interface 302 is inserted into the inside of the rubber sealing ring 201. The rubber sealing ring 201 plays a sealing role.

[0031] An extension pipe 7 is connected through one side of the regulating pipe 4, and a positioning pipe 8 is connected through one side of the extension pipe 7. The positioning pipe 8 serves to connect to the external pipe.

[0032] A flange connector 9 is fixedly connected to one side of the positioning tube 8. Several positioning holes are opened on the surface of the flange connector 9. The flange connector 9 serves to fix the equipment.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: When using, insert the outer interface 302 into the main pipe 1 so that the rubber sealing ring 201 installed inside the main pipe 1 fits tightly against the surface of the outer interface 302. The support spring 202 installed inside the rubber sealing ring 201 further improves the sealing performance of the rubber sealing ring 201. Next, wrap the sealing strip 303 around the thread of the outer interface 302. Then slide the tapered tube 301 on the surface of the main pipe 1 and rotate the tapered tube 301 so that the tapered tube 301 is tightly fixed to the surface of the outer interface 302 by means of the thread structure.

[0036] The second step: When using the pipe, the staff needs to drain the old pipe in sections or perform a pressure test on the newly installed pipe. The rotating handle 501 on the surface of the regulating pipe 4 can be rotated so that the closed hemisphere 502 at the bottom of the rotating handle 501 rotates inside the regulating pipe 4. The water flow and pressure inside the regulating pipe 4 can be adjusted by the angle formed with the pipe wall. With the pressure gauge 6 installed on one side, the pressure value inside the pipe can be displayed accurately in real time and the pressure can be adjusted to a suitable range.
