Description

Technical Field

[0001] The present invention relates to the technical field of pipeline pressure testing, and more specifically, to a heating pipeline pressure testing device. Background Art

[0002] The heating pipeline pressure test device can detect the pipeline's tightness and pressure bearing capacity by applying a certain pressure to the pipeline. This is the key to the safe operation of the heating system, because if the pipeline leaks or cannot withstand the working pressure, it will lead to poor heating effect and even cause safety accidents. The pressure test device can detect and solve these problems in time to ensure the normal operation of the heating system.

[0003] In the existing public documents, the Chinese patent announcement number CN116577023A discloses a pipeline pressure test device. This pressure test technology is to place the pipeline to be pressure tested on a placement rack, and then start the locking motor. The locking motor drives the screw to rotate, and the screw drives the moving block to move horizontally under the guidance of the guide rod, thereby driving the support plate to move horizontally. At this time, the end cover on the support plate will push the pipeline until the flanges at both ends of the pipeline are respectively embedded in the inside of the two sets of end covers and are tightly fixed with the end covers. The assembly of the pipeline can be completed, and then the pressure test pump can be started to perform the pressure test of the pipeline. In this way, the assembly operation of the pipeline is very simple and more convenient to use. It solves the problem that the assembly of the pipeline requires the use of multiple sets of bolts to achieve connection and fixation, which is very cumbersome to operate and not convenient to use. However, this technology has the following defects.

[0004] When the heating pipeline is undergoing a pressure test, fluid pressure is mainly applied to the heating pipeline to see whether the pressure can be stabilized within a specified range, so as to determine whether there is a leakage problem in the heating pipeline. However, the heating pipeline is long, and it is difficult to accurately know the specific leakage location of the specified horizontal area and longitudinal interval area of ​​the heating pipeline. Maintenance personnel also need to spend a lot of time to observe and find the specific leakage location of the pressure test, and it is difficult to accurately know the leakage problem area of ​​the pressure failure. This leads to poor accuracy in the pressure test of the heating pipeline, and for this reason a heating pipeline pressure test device is required. Summary of the invention

Locking valves are threadedly connected to both ends of the heating pipe, and the two locking valves are symmetrically arranged about the heating pipe.

[0008] When using this technology, a leakage pressure test area on a heating pipe is selected, and the reduction motor is started. The bidirectional screw drives the two threaded strips to approach each other under the action of the thread transmission force, so that the threaded strip moves up and the other threaded strip moves down. The pressure plate drives the two arc-shaped pressure plates up, and the two transverse rubber rings can realize the sealing pressure test operation of the transverse interval area. The pressure block drives the extrusion strip to move up, and the extrusion strip drives the rubber jacket to move up, so that the rubber jacket can be squeezed and sealed with the pressure test ring. The longitudinal sealing strip is squeezed at the bottom position of the outer wall of the heating pipe, and the upper longitudinal sealing strip is squeezed and sealed at the top position of the outer wall of the heating pipe, so that the two longitudinal sealing strips can realize the interval sealing operation of the longitudinal area of ​​the heating pipe. A left cavity area is formed inside the pressure test ring, and a right cavity area is formed inside the pressure test ring.

[0009] Preferably, the pressure test area positioning mechanism includes a lower row valve fixedly arranged at the bottom end of the lower row pipe, and the lower row pipe is fixedly connected to the pressure test ring; the pressure test area positioning mechanism also includes a second pressure sensor, a nozzle, a support ring and a barcode; the second pressure sensor is fixedly plugged into one side of the outer wall of the lower row pipe, and the nozzle is fixedly connected to the bottom end of the lower row valve, the support ring is fixedly installed on the outer wall of the nozzle, and the barcode is fixedly connected to one side of the outer wall of the support ring. The inner wall diameter of the top end of the nozzle is larger than the inner wall diameter of the bottom end, and the inner walls of the nozzle and the lower row pipe are both smooth surfaces.

[0010] When this technology is in use, the leaked water is pressurized into the lower pipe, and at the same time the lower valve closes the lower pipe. When the second pressure sensor senses a pressure value, the lower valve is opened, so that the leaked water flows through the lower valve into the sprinkler head, and the sprinkler head realizes the downward spraying operation.

When the humidity sensor senses the humidity of the water body leaking from the nozzle, after sensing the humidity, the barcode recognition sensor simultaneously recognizes the barcode. At this time, the controller turns on the left area indicator light, and the maintenance personnel who arrive at the scene can accurately know the specific area location of the pressure measurement leakage fault of the heating pipeline.

[0013] Technical effects and advantages of the present invention: 1. The present invention uses a transverse and longitudinal interval pressure test mechanism. When a heating pipe has a leakage problem, the support frame drives the pressure test ring to make the two transverse rubber rings slide right on the outer wall of the heating pipe, select a leakage area on the heating pipe, and the reduction motor drives the bidirectional screw to rotate. The two thread sleeves approach each other under the action of the thread transmission force, and the transverse rubber ring can be squeezed and sealed on the heating pipe. The two transverse rubber rings can realize the sealing pressure test operation of the transverse interval area. The extrusion strip drives the rubber outer sleeve to move upward, and the longitudinal sealing strip is squeezed at the bottom position of the outer wall of the heating pipe, while the upper longitudinal sealing strip is squeezed and sealed at the top position of the outer wall of the heating pipe, forming a left cavity area inside the pressure test ring and a right cavity area inside the pressure test ring, so that the specific area of ​​the heating pipe pressure test failure leakage can be accurately known, and the pressure test accuracy of the heating pipe is greatly improved.

[0014] 2. The present invention adopts a pressure test area positioning mechanism. The leaked water is pressurized into the lower pipe. At the same time, the lower valve closes the lower pipe. When the second pressure sensor senses a pressure value, the lower valve is opened, and the leaked water enters the nozzle along the lower valve. The nozzle realizes the downward spraying operation. The support ring supports the barcode to increase the stability of the barcode. The specific leakage position of the specified horizontal area and the longitudinal interval area of ​​the heating pipeline can be accurately sensed and marked, thereby greatly improving the pressure test accuracy of the heating pipeline.

[0015] 3. The present invention adopts a displacement pressure test detection component. The rotating motor drives the rotating rod to rotate, the rotating rod drives the rotating shaft to rotate, the sleeve rotating bar causes the ring to rotate, and at the same time the ring drives the humidity sensor to rotate, the sleeve rotating bar drives the barcode recognition sensor to rotate, the barcode recognition sensor rotates below the barcode, and the humidity sensor senses the humidity of the water leaked from the nozzle. After sensing the humidity, the barcode recognition sensor recognizes the barcode. After the area indicator light is on, a pressure measurement leakage fault occurs at the heating pipe position in the left cavity area inside the pressure test ring, thereby greatly improving the pressure test accuracy of the heating pipe.

[0016] The mutual influence of the above-mentioned multiple effects first enables the two horizontal rubber rings to realize the sealing pressure test operation of the horizontal spacing area, the longitudinal sealing strip is squeezed at the bottom position of the outer wall of the heating pipe, and the upper longitudinal sealing strip is squeezed and sealed at the top position of the outer wall of the heating pipe. Then, when the second pressure sensor senses the pressure value, the lower valve is opened, and the leaked water enters the nozzle along the lower valve to be sprayed downward. Finally, when the humidity sensor senses the humidity of the leaked water sprayed out of the nozzle, the barcode recognition sensor recognizes the barcode. In summary, the specific leakage position of the specified horizontal area and the longitudinal spacing area of ​​the heating pipeline can be accurately sensed and marked, and the specific area of ​​the heating pipeline pressure test failure can be accurately known, which greatly improves the accuracy of the pressure test of the heating pipeline.

[0033] A test valve 21 is fixedly connected to the bottom of the outer wall of the heating pipe 3 and near the position of the first pressure sensor 4. A booster pump 22 is fixedly connected to the bottom of the test valve 21. A butt-jointed threaded pipe 23 is fixedly connected to the input end of the booster pump 22. Locking valves 38 are threadedly connected to both ends of the heating pipe 3. The two locking valves 38 are symmetrically arranged about the heating pipe 3. In order to close the two locking valves 38 through the controller 19, the tap water pipe to be tested is threadedly butt-jointed to the inner wall of the butt-jointed threaded pipe 23, and the booster pump 22 is started by the controller 19, so that the water body to be tested is pressurized to enter the position of the test valve 21. After the test valve 21 is opened, the pressurized water body is poured into the interior of the heating pipe 3. When the pressure value sensed by the first pressure sensor 4 is the same as the test pressure value and is maintained at the pressure value position, the heating pipe 3 does not have leakage or damage problems.

[0034] In this embodiment, as shown in the attached Figure 7- Attachment Figure 8 As shown, the pressure test area positioning mechanism includes a lower row valve 25 fixedly arranged at the bottom end of the lower row pipe 24, and the lower row pipe 24 is fixedly connected to the pressure test ring 1; the pressure test area positioning mechanism also includes a second pressure sensor 26, a nozzle 27, a support ring 28 and a barcode 29; the second pressure sensor 26 is fixedly plugged into one side of the outer wall of the lower row pipe 24, and the nozzle 27 is fixedly connected to the bottom end of the lower row valve 25, the support ring 28 is fixedly installed on the outer wall of the nozzle 27, and the barcode 29 is fixedly connected to one side of the outer wall of the support ring 28. The inner wall diameter of the top end of the nozzle 27 is larger than the inner wall diameter of the bottom end thereof, and the inner walls of the nozzle 27 and the lower row pipe 24 are both smooth surfaces.

[0035] In this embodiment, as shown in the attached Figure 7 - Attachment Fig.10 As shown, the displacement pressure test detection assembly includes a rotating motor 30 fixedly arranged on the lower surface of the pressure plate 9; a rotating rod 31 is fixedly installed at the output end of the rotating motor 30, and a rotating shaft 32 is fixedly connected to the bottom end of the rotating rod 31, and a sleeve rotating bar 33 is fixedly connected to the outer wall of the rotating shaft 32, and a sleeve rotating bar 34 is fixedly connected to the bottom end of the sleeve rotating bar 33; a humidity sensor 35 is fixedly installed on the inner wall of the sleeve rotating bar 34, a bar code recognition sensor 36 is provided on one side of the sleeve rotating bar 34, and two area indicator lights 37 are fixedly installed on the top of the outer wall of the pressure test ring 1. The bar code recognition sensor 36 is fixedly connected to the sleeve rotating bar 33, and the sleeve rotating bar 33 is used to support the humidity sensor 35.

[0036] The method of using the heating pipeline pressure testing device of the present invention is as follows: Step 1: During the closed pressure test, the controller 19 is powered by the battery 17, the hand is held on the outer wall of the holding rod 18, and the two limit rings 20 limit the hand, and the two locking valves 38 are closed by the controller 19 to achieve the closed operation of the heating pipe 3. At the same time, the threaded tap water pipe to be tested is docked on the inner wall of the docking threaded pipe 23, and the booster pump 22 is started by the controller 19, so that the tested water body is pressurized to enter the position of the test valve 21, and the pressurized water body is poured into the heating pipe 3 after the test valve 21 is opened. At the same time, the first pressure sensor 4 senses the pressure value inside the heating pipe 3. When the pressure value sensed by the first pressure sensor 4 is the same as the test pressure value, and it is maintained at the pressure value position, the heating pipe 3 does not have leakage damage. When the pressure value sensed by the first pressure sensor 4 is lower than the test value set by the controller 19, the heating pipe 3 has a leakage problem.

[0037] Step 2: During the horizontal and vertical interval pressure test, when the heating pipe 3 is pressurized and leaks, it is moved by holding on the holding rod 18, and the holding rod 18 drives the support frame 5 to move right, and the support frame 5 drives the pressure test ring 1 to make the two horizontal rubber rings 2 slide right on the outer wall of the heating pipe 3. A leakage pressure test area on a heating pipe 3 is selected, and the reduction motor 7 is started. The reduction motor 7 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the two threaded strips 8 to approach each other under the action of the thread transmission force, so that the threaded strip 8 moves up, and the other threaded strip 8 moves down, and the threaded strip 8 drives the pressure plate 9 to move up, and the pressure plate 9 drives the two arc pressure plates 14 to move up, and the arc pressure plate 14 squeezes the transverse rubber ring 2, and the transverse rubber ring 2 can be squeezed and sealed on the heating pipe 3. Since the two arc pressure plates 14 move in opposite directions and the structure is symmetrically arranged vertically, the other arc pressure plate 14 moves down and squeezes on the transverse rubber ring 2, so that the two transverse rubber rings 2 can realize the sealing pressure test operation of the transverse interval area.

[0038] At the same time, the pressing plate 9 drives the pressing block 10 to move upward, the pressing block 10 drives the extrusion strip 11 to move upward, the extrusion strip 11 drives the rubber jacket 12 to move upward, and the rubber jacket 12 moves upward along the inner wall of the pressure test ring 1, so that the rubber jacket 12 can be squeezed and sealed with the pressure test ring 1. At the same time, the extrusion strip 11 squeezes the longitudinal sealing strip 13, and the longitudinal sealing strip 13 is squeezed at the bottom position of the outer wall of the heating pipe 3, and the upper longitudinal sealing strip 13 is squeezed and sealed at the top position of the outer wall of the heating pipe 3. Since the two longitudinal sealing strips 13 are symmetrically arranged, and the two longitudinal sealing strips 13 move in a manner of moving toward each other, the other longitudinal sealing strip 13 moves downward and is squeezed at the top position of the outer wall of the heating pipe 3, so that the two longitudinal sealing strips 13 can realize the interval sealing operation of the longitudinal area of ​​the heating pipe 3. A left cavity area is formed inside the pressure test ring 1, and a right cavity area is formed inside the pressure test ring 1. The support block 16 is supported by the support frame 5, and the support block 16 supports the torque sensor 15. The torque sensor 15 senses the torque of the bidirectional screw 6. When the torque value sensed by the torque sensor 15 is the same as the torque value set by the controller 19, the reduction motor 7 is turned off by the controller 19. When the left cavity area inside the pressure test ring 1 is filled with water leaking from the heating pipe 3, the leaked water enters the lower discharge pipe 24 from the inside of the pressure test ring 1.

[0039] Step 3: When the pressure test area is located, the leaked water is pressurized into the lower pipe 24, and the lower valve 25 closes the lower pipe 24, so that the second pressure sensor 26 senses the pressure of the lower pipe 24. When the second pressure sensor 26 senses the pressure value, the lower valve 25 is opened, so that the leaked water flows along the lower valve 25 into the nozzle 27, and the nozzle 27 realizes the downward spraying operation, and the nozzle 27 supports the support ring 28, and the support ring 28 supports the barcode 29, thereby increasing the stability of the barcode 29.

[0040] Step 4: During the displacement pressure test, the controller 19 is used to start the rotation motor 30, the rotation motor 30 drives the rotating rod 31 to rotate, the rotating rod 31 drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the sleeve rotating bar 33 to rotate, and the sleeve rotating bar 33 causes the sleeve ring 34 to rotate. At the same time, the sleeve ring 34 drives the humidity sensor 35 to rotate, and the humidity sensor 35 rotates under the nozzle 27. At the same time, the sleeve rotating bar 33 drives the barcode recognition sensor 36 to rotate, and the barcode recognition sensor 36 rotates under the barcode 29. When the humidity sensor 35 senses the humidity of the water body leaking from the nozzle 27, after sensing the humidity, the barcode recognition sensor 36 simultaneously performs barcode recognition on the barcode 29. In this way, the controller 19 turns on the left area indicator light 37. When the area indicator light 37 is on, a pressure leakage fault occurs at the position of the heating pipe 3 in the left cavity area inside the pressure test ring 1. In this way, maintenance personnel can accurately know the specific area location of the pressure leakage fault of the heating pipe 3 when they arrive at the scene, without the need to conduct large-scale inspection and treatment of the heating pipe 3.
