Technical Field

[0001] The utility model relates to the field of pipeline testing, in particular to a pipeline water pressure sealing testing device. Background Art

[0002] Pipelines, as a basic engineering structure, are channels for transporting liquid, gas or solid particle fluids. They are widely used in various industries and fields, such as oil and gas industry, chemical industry, water treatment, urban water supply and drainage, heating systems, food processing, pharmaceuticals, mining and construction. Testing the water pressure and tightness of pipelines is a necessary step to ensure the safe and reliable operation of the pipeline system. The purpose of the test is to verify whether the pipeline can maintain integrity and tightness under the design pressure.

[0003] The existing pipeline water pressure tightness test usually uses a sealing tool to seal one side of the pipeline, then injects water from the other side of the pipeline, and then needs to add an additional sealing ring for sealing, and then test the pipeline water pressure tightness. The current water pressure tightness test method is inconvenient for the installation and removal of the sealing tool, resulting in poor convenience of equipment use.

[0004] Therefore, it is necessary to design a pipeline water pressure tightness testing device that can be installed and disassembled, is simple to operate, and improves the convenience of use. Utility Model Content

[0006] The technical solution is: a pipeline water pressure sealing test device, including a pipeline, a base, wheels, a pressure pump, a pressure pipe, a mounting plate, a water injection pipe, an exhaust pipe, a detection assembly and a sealing assembly. The lower sides of the left and right parts of the base are both provided with front and rear supporting feet through threads, and the lower sides of the left and right parts of the base are rotatably connected with wheels, and the wheels are located on the inner sides of adjacent supporting feet. The upper side of the base is connected to a pressure pump, and the pressure pump is connected to a pressure pipe. The rear side of the pressure pipe is connected to a mounting plate, and a pipeline is fixed to the mounting plate through a sealing assembly. A mounting plate is also installed on the other end of the pipeline. The front right front side of the front mounting plate is connected to a water injection pipe, and the upper front side of the front mounting plate is connected to an exhaust pipe. Detection assemblies are provided on the outer sides of the mounting plates, and sealing assemblies are provided on the inner sides of the mounting plates.

[0007] Furthermore, the detection component includes a pressure gauge, a fixing bracket, a detector and an indicator light. The pressure gauge is connected to the front left side of the front mounting plate, the outer side of the mounting plate is connected to the fixing bracket, a plurality of detectors are connected to the fixing bracket, a plurality of indicator lights are connected to the outer side of the fixing bracket, and the detectors are electrically connected to adjacent indicator lights.

[0008] Furthermore, the sealing assembly includes a screw, a conical column, a rubber tube and a rubber ring. The middle part of the mounting plate is connected to the screw through a thread, the inner side of the screw is rotatably connected to the conical column, the inner side of the mounting plate is connected to the rubber tube, the rubber tube is in contact with the pipeline, the inside of the rubber tube is connected to the rubber ring, and the rubber ring is in contact with the adjacent conical column.

[0009] Furthermore, a handle is provided on the front side of the screw rod.

[0010] Furthermore, it also includes a first valve, and the first valve is rotatably connected to the water injection pipe.

[0011] Furthermore, a second valve is also included, and the exhaust pipe is rotatably connected to the second valve.

[0012] Beneficial effects: 1. The utility model makes the installation sheet contact with the pipe to be tested, so that the rubber tube and the rubber ring are inserted into the pipe for installation, and the installation sheet is removed, and then the pressure gauge, the fixing bracket, the detector, the indicator light, the screw, the cone column, the rubber tube and the rubber ring are removed, so that the water in the pipe flows out, so that the device can be installed and disassembled, the operation is simple, and the convenience of use is improved.

[0013] 2. In the process of stabilizing the pressure, if the pressure gauge reading drops, it indicates that there is leakage in the pipeline. If there is a crack in the pipeline, water will leak during the pressurization process. When the detector detects a leak, the indicator light will light up, so that the water pressure and sealing of the pipeline can be tested. The operation is simple, and safety accidents such as rupture and explosion can be prevented. It is convenient to test the strength and sealing of the pipeline, and improve the quality of the pipeline and the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

The pressure gauge 10 is connected to the front left side of the front mounting piece 5, and the outer side of the mounting piece 5 is connected to the fixing frame 11. Four detectors 12 are connected to the fixing frame 11, and four indicator lights 13 are connected to the outer side of the fixing frame 11. The detectors 12 are electrically connected to adjacent indicator lights 13. A sealing component is provided on the inner side of the mounting piece 5, and the sealing component includes a screw 14, a cone column 15, a rubber tube 16 and a rubber ring 17. The middle part of the mounting piece 5 is connected to the screw 14 by threading, and a handle is provided on the front side of the screw 14 for easy hand-holding and rotation of the screw 14. The inner side of the screw 14 is rotatably connected to the cone column 15, and the inner side of the mounting piece 5 is connected to the rubber tube 16, and the rubber tube 16 is in contact with the pipeline 0. The inside of the rubber tube 16 is connected to a rubber ring 17, and the rubber ring 17 is in contact with the adjacent cone column 15.

[0019] When it is necessary to test the water pressure and tightness of the pipe 0, the device can be used. The wheel 2 is used to move the device to the place where the water pressure and tightness of the pipe 0 need to be tested. Then, the supporting feet are rotated by hand to move the device so that the supporting feet on the base 1 are in contact with the ground, thereby supporting the device. Then, the installation sheet 5 is in contact with the pipe 0 to be tested, so that the rubber tube 16 and the rubber ring 17 are inserted into the pipe 0 for installation. Then, the screw rod 14 is rotated by the handle, and the screw rod 14 is moved under the action of the thread, thereby driving the screw rod 14 to move.

The operation is simple, and safety accidents such as rupture and explosion are prevented. It is convenient to test the strength and sealing of the pipeline 0, and improve the quality and safety of use of the pipeline 0.

Then the support foot is rotated to move in the opposite direction, so that the wheel 2 contacts the ground, and then the device can be moved away.
