Description

Technical Field

[0001] The invention belongs to the technical field of pipeline component safety performance testing, and in particular relates to a pipeline component performance testing device. Background Art

[0002] Pipeline components are the basic components of pressure pipeline component systems. They are mainly used to connect, branch, control, adjust and support pipeline components. Pipeline components are usually straight pipes with two connection ends. Before leaving the factory, pipeline components need to undergo safety performance tests, that is, their pressure resistance and sealing performance are tested by test equipment to ensure the safety performance of pipeline components under actual working conditions.

[0003] In the prior art, the test equipment is usually connected to the two connecting ends of the pipeline element through two sealing end covers arranged at intervals along the horizontal direction, and then water is injected into the pipeline element to perform a water pressure test. At the same time, the sealing between the sealing end cover and the connecting end is also tested to ensure the safety performance of the subsequent use of the key components. However, during the installation of the pipeline element, the pipeline element is usually suspended, mainly clamped by two sealing end covers (both sealing end covers are connected to the top column and can move laterally, see patent number: CN202020415274.8; patent name: A pipeline element high-pressure water test device), which has poor stability, is not easy to disassemble and assemble, and has poor installation accuracy, which affects the test accuracy and has poor practicality. Of course, there is also a method of directly placing the pipeline element on a horizontally set table, but this method is not convenient for adapting to pipeline elements of different diameters and has poor adaptability.

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] Please also read Figure 1 and Figure 2, the pipeline element performance test equipment provided by the present invention is now described. The pipeline element performance test equipment includes a base 10, a connecting mechanism 20 and a clamping mechanism. The base 10 has a horizontally arranged mounting platform 11 on the top. There are two connecting mechanisms 20, and the two connecting mechanisms 20 are arranged on the mounting platform 11 at intervals. Each connecting mechanism 20 has a mating portion arranged toward the other connecting mechanism 20. The two connecting mechanisms 20 can respectively drive the two mating portions to move relative to each other and be sealed and connected with the two connecting ends of the pipeline element 40 to be tested. The clamping mechanism is arranged between the two connecting mechanisms 20 and is fixed on the mounting platform 11. The clamping mechanism can clamp the pipeline element 40 to be tested before the two mating portions are connected to the pipeline element 40 to be tested, and the axis of the pipeline element 40 to be tested is arranged in a colinear manner with the central axis of each mating portion.

[0054] Compared with the prior art, the pipeline component performance test equipment provided in this embodiment has two connection mechanisms 20 arranged on the base 10 that can ensure docking with the two ends of the pipeline component 40 to be tested, which is convenient for the installation of the pipeline component 40 to be tested. The clamping mechanism arranged between the two connection mechanisms 20 can ensure that the pipeline component 40 to be tested is clamped and fixed before the connection structure is docked with the pipeline component 40 to be tested, and the axis of the pipeline component 40 to be tested is arranged in line with the central axis of each mating part, which can ensure the stability of the two mating parts and the two connection ends of the pipeline component 40 to be tested after docking, and can ensure the test accuracy, and has strong practicality. In addition, the clamping mechanism can also adapt to pipeline components 40 of different specifications, so that the axis of the pipeline components 40 of each specification after being clamped and fixed is arranged in line with the central axis of each mating part, and has strong adaptability.

[0055] It should be noted that the pipeline element 40 to be tested is usually a straight pipe type, with flanges provided at both ends thereof, and the flanges also provide an annular butt joint surface as a connection end.

[0056] In some embodiments, the connection mechanism 20 may be configured as follows: Figure 1 See the structure shown. Figure 1Each connection mechanism 20 includes a fixed cylinder 21, a slide 22, a first telescopic structure 23 and a docking joint 24. The fixed cylinder 21 has a through slide cavity arranged along the spacing direction of the two connection mechanisms 20, and the fixed cylinder 21 is fixed above the mounting platform 11 through a first support member 12 arranged on the mounting platform 11. The slide 22 is slidably arranged in the through slide cavity, and one end of the slide 22 close to another connection mechanism 20 extends out of the through slide cavity. The first telescopic structure 23 is fixed on the fixed cylinder 21 and connected to the slide 22, and can drive the slide 22 to move. The docking joint 24 is detachably connected to the end of the slide 22, and the docking joint 24 has a connecting cavity that can be connected to the pipeline element 40 to be tested, and the docking joint 24 has an annular end face that can be matched with the connecting end of the pipeline element 40 to be tested, and a sealing rubber pad is fixed on the annular end face. The docking joint 24 is a matching part, and the docking joint 24 can be connected to an external water supply module, and can inject water into the pipeline element 40 to be tested.

[0057] In each connection mechanism 20, the first telescopic structure 23 drives the slide 22 to move in the through slide cavity, so as to drive the joint 24 to approach or move away from the pipeline component 40 to be tested. This structure can facilitate disassembly and assembly. Moreover, the slides 22 in the two connection mechanisms 20 are independently driven, which can adapt to the position of the pipeline component 40 to be tested, and avoid slippage on the clamping mechanism after a large pressure appears on a certain connection end of the pipeline component 40 to be tested.

[0058] In some embodiments, the above-mentioned joint 24 can be used as follows Figure 1 See the structure shown. Figure 1 One of the butt joints 24 is provided with a connecting water pipe 25 to which an external water supply module can be connected, and the other butt joint 24 is provided with a water pressure gauge. The connecting water pipe 25 can be connected to the external water supply module to ensure that after the pipeline element 40 to be tested is docked with the two butt joints 24, water can be injected into the pipeline element 40 to be tested, and a pressure test can be performed, and the water pressure can be checked through the water pressure gauge.

[0059] In this embodiment, an annular end face is provided at the end of each butt joint 24, and the annular end face can be adapted to abut against the connection end of the pipeline element 40 to be tested, and the sealing is achieved through the annular sealing rubber gasket, thereby achieving a butt joint effect. During the water pressure test, as the water pressure increases, the sealing effect of the sealing rubber gasket is also tested, and the water pressure is usually adjusted to 130% of the set pressure to ensure the safety of the element to be tested. In addition, a pipe hole penetrating the annular end face is provided in each butt joint 24 to ensure water injection.

[0060] After the water injection is completed, the water in the pipeline element 40 to be tested needs to be pumped out. This can be done through the water supply module. At the same time, a solenoid valve for balancing the air pressure is provided on the other docking joint 24 to ensure that the air pressure in the pipeline element 40 to be tested is balanced during the water injection and pumping process. This method is a conventional setting for those skilled in the art and is a prior art, which will not be described in detail here.

[0061] In some embodiments, the above-mentioned joint 24 can be used as follows Figure 1 See the structure shown. Figure 1 The butt joint 24 and the slide seat 22 are threadedly connected. This structure can ensure that butt joints 24 of different specifications can be replaced according to the pipeline components 40 to be tested with different pipe diameters, and has strong adaptability.

[0062] Specifically, each docking joint 24 is provided with a screw at one end away from the annular end surface, and each slide seat 22 is provided with a threaded hole threadably connected to the screw at one end close to the clamping mechanism. This structure is easy to assemble and disassemble, has high connection strength, and is easy to operate.

[0063] In some embodiments, the clamping mechanism may be Figures 1 to 3 See the structure shown. Figures 1 to 3 , set the spacing direction of the two connecting mechanisms 20 to be the first direction.

[0064] The clamping mechanism includes a fixed frame 31, a clamping assembly 32, a distance measuring assembly 33 and a matching controller. The fixed frame 31 is fixedly mounted above the mounting platform 11 through a second support member 13 arranged on the mounting platform 11. The fixed frame 31 has a notch that penetrates along the first direction. Two clamping assemblies 32 are provided, and the two clamping assemblies 32 are respectively located on both sides of the matching portion along the vertical direction, and are both connected to the fixed frame 31. Each clamping assembly 32 has a clamping end, and the two clamping assemblies 32 can respectively drive the two clamping ends to move relative to each other to clamp the pipeline element 40 to be measured. Two distance measuring assemblies 33 are provided, and the two distance measuring assemblies 33 are respectively fixedly mounted on the two clamping assemblies 32. The two distance measuring assemblies 33 correspond to a target surface 34 fixedly mounted on the fixed frame 31 and having a height that is flush with the height of the central axis of the matching portion. The two distance measuring assemblies 33 can respectively measure the stroke of the two clamping ends so that the axis height of the clamped pipeline element 40 to be measured is flush with the height of the central axis of each matching portion.

[0065] The notch formed by the fixing frame 31 can ensure that the pipeline component 40 to be tested is installed, and also provides a moving space for the two clamping assemblies 32. The two clamping assemblies 32 can clamp the pipeline component 40 to be tested in the vertical direction, and can drive the pipeline component 40 to be tested to move during the clamping and fixing process, so that the axis of the pipeline component 40 to be tested is arranged in a colinear manner with the axis of the two butt joints 24, which can adapt to pipeline components 40 with different diameters and can also ensure the test effect.

[0066] The distance measuring component 33 can measure the moving stroke of the two clamping ends respectively, thereby ensuring that the axis of the pipe element 40 clamped between the two clamping ends is highly flush with the axis of each docking joint 24, ensuring the docking effect, and then ensuring the test effect. At the same time, it can also adapt to pipe elements 40 of different diameters, with strong adaptability and practicality.

[0067] In some embodiments, the clamping assembly 32 may be configured as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 Each clamping assembly 32 includes a lifting slide 321, a second telescopic structure 322, a clamping claw 323 and an angle adaptation structure 324. The lifting slide 321 is located in the notch and is slidably connected to the fixed frame 31 in the vertical direction. There are at least two second telescopic structures 322, each of which is fixed on the fixed frame 31 and connected to the lifting slide 321. The clamping claw 323 is located on the side of the lifting slide 321 close to another clamping assembly 32. The angle adaptation structure 324 is arranged in the lifting slide 321 and has a transfer end connected to the clamping claw 323. The angle adaptation structure 324 can make the axis of the pipeline element 40 to be tested and the central axis of each mating part be arranged in a colinear manner after the pipeline element 40 to be tested is clamped by the clamping claw 323 and the pipeline element 40 to be tested is docked by two mating parts.

[0068] The lifting slide 321 can move in the vertical direction driven by the second telescopic structure 322 , wherein the upper lifting slide 321 moves downward, and the lower lifting slide 321 moves upward, so as to clamp and fix the pipeline component 40 to be tested.

[0069] Regarding the clamping space formed between the two clamping claws 323, because it needs to adapt to pipe elements 40 of different diameters, when the pipe element 40 with a small diameter is placed, it can only ensure that the height of the axis of the pipe element 40 is flush with the height of the central axis of each pair of joints 24, but it will have a certain deflection in the first direction, that is, the axis of the pipe element 40 has a certain deflection in the first direction, which will cause the docking effect of the two ends of the pipe element 40 to deteriorate. The axis of the pipe element 40 can be corrected by the angle adaptation structure 324, thereby ensuring that the axis of the pipe element 40 and the axis of each pair of joints 24 are arranged in the same line. This structure can effectively ensure the docking effect, thereby ensuring the test effect, and is highly practical.

[0070] In some embodiments, the clamping claw 323 may be Figure 1 See the structure shown. Figure 1 Each clamping claw 323 has an arc-shaped concave portion arranged toward the other clamping assembly 32, and the axis of the arc-shaped concave portion is arranged along the first direction to ensure the insertion of the pipeline component 40 to be tested.

[0071] Specifically, each clamping claw 323 is provided with teeth 325 spaced apart along the first direction.

[0072] Specifically, the teeth 325 on the two clamping claws 323 are staggered.

[0073] A clamping space for fixing the pipe element 40 is formed between the two clamping claws 323, thereby ensuring the clamping of the pipe element 40 to be tested. In addition, each clamping claw 323 is provided with a tooth 325, and the two clamping claws 323 can be engaged with each other during the relative movement, which can ensure that it can adapt to pipe elements 40 of different diameters, thereby improving adaptability and practicality.

[0074] In some embodiments, the distance measuring component 33 may be implemented as follows: Figure 2 See the structure shown. Figure 2 The distance measuring component 33 is a laser distance measuring device, and the distance measuring component 33 is fixed on the lifting slide 321.

[0075] The specific working principle is that the target surface 34 is a laser target surface 34, and its height is flush with the center axis height of each joint 24. When the clamping assembly 32 located at the top moves downward, the distance between the lifting slide 321 and the target surface 34 will be monitored in real time. At the same time, when the clamping assembly 32 located at the bottom moves upward, the distance between the lifting slide 321 and the target surface 34 will also be monitored in real time. The clamped part of the pipeline component 40 to be tested is cylindrical, so the moving strokes of the two lifting slides 321 need to be consistent to ensure that the axis of the pipeline component 40 to be tested is at the same height as the axis of each joint 24. This structure can effectively adapt to pipelines of different diameters to be tested and has strong adaptability.

[0076] In some embodiments, the angle adaptation structure 324 may be implemented as follows: Figures 4 to 6 See the structure shown. Figures 4 to 6 The angle adaptation structure 324 includes a sliding shaft 3241, a lifting groove 3243, a correction rod 3244, a first spring 3245 and a correction component. The sliding shaft 3241 is slidably arranged in a sliding hole in the lifting slide 321 along a vertical direction, and a prism block 3242 is fixed on the sliding shaft 3241. The lifting groove 3243 is rotatably connected to the sliding shaft 3241 through a thrust bearing, and is slidably arranged in a limiting sliding cavity 326 in the lifting slide 321 along a vertical direction. The correction rod 3244 is arranged in the lifting groove 3243 along a first direction, and is fixed on the sliding shaft 3241, and both ends of the correction rod 3244 extend out of the sliding shaft 3241. The first spring 3245 is located at the top of the sliding shaft 3241, and can push the sliding shaft 3241, so that the sliding shaft 3241 has a tendency to continuously move toward another clamping assembly 32. Two correction components are provided, and the two correction components correspond to the two protruding ends of the correction rod 3244 respectively. Each correction component includes two second springs 3246, and the two second springs 3246 are respectively arranged on both sides of the correction rod 3244. One end of each second spring 3246 is connected to the inner wall of the lifting groove 3243, and the other end is connected to the correction rod 3244. The correction component can make the correction rod 3244 continue to have a tendency to rotate along the first direction.

[0077] Among them, a clamping groove for the prism block 3242 to adapt to is provided on the end surface of the limiting sliding cavity 326 close to the other clamping component 32, and the clamping groove is connected to the sliding hole.

[0078] Due to the clamping space formed by the two clamping jaws 323, after the pipeline component 40 is installed, it will deflect in a certain direction in the first direction, that is, the axis of the pipeline component 40 deflects in the first direction. At this time, as the second telescopic structure 322 continues to drive the lifting slide 321, the sliding shaft 3241 will move relative to the lifting slide 321. Then, the prism block 3242 on the sliding shaft 3241 will enter the limiting sliding cavity 326 after disengaging from the clamping groove. At this time, the combination of the sliding shaft 3241 and the clamping jaws 323 can rotate. Then, after the pipeline component 40 is squeezed by the docking heads 24 on both sides, it will be corrected so that its axis is collinear with the axes of the respective docking heads 24.

[0079] After the test is completed, when the two lifting slides 321 move away from each other, the pipeline component 40 is taken out. At this time, each first spring 3245 will push each sliding shaft 3241 back to its initial position (the prism block 3242 enters the clamping groove). However, at this time, it is necessary to ensure that the axis of the arc-shaped concave surface on the clamping jaw 323 is collinear with the first direction. Therefore, before the first spring 3245 pushes each sliding shaft 3241 back to its initial position and after the two docking heads 24 come into contact with the pipeline component 40, the deviation correction rod 3244 is pushed by each second spring 3246 so that the deviation correction rod 3244 is arranged along the first direction. Then, the axis of the arc-shaped concave surface on the clamping jaw 323 is arranged along the second direction, which is convenient for the prism block 3242 to enter the clamping groove and is also convenient for the next test work, with strong practicability.

[0080] The lifting groove 3243 is rotationally connected to the sliding shaft 3241 through a thrust bearing. At the same time, the lifting groove 3243 is slidably arranged in the limiting sliding cavity 326 in the lifting slide 321. It can move synchronously with the sliding shaft 3241, so that each second spring 3246 also moves synchronously with the sliding shaft 3241, which is convenient for the stable operation of the deviation correction component. In addition, the lifting groove 3243 will not deflect in the limiting sliding cavity 326, which can ensure the deviation correction effect on the sliding shaft 3241. Preferably, the lifting groove 3243 can have a "U"-shaped outer contour structure.

[0081] In this embodiment, the lifting slide 321 may include a seat body and a cover plate 3247 bolted to the seat body. For reference, see Figure 4 and Figure 5 . A fixed sliding cylinder 3248 for the sliding shaft 3241 to extend out is provided on the cover plate 3247. At the same time, the first spring 3245 is arranged in the fixed sliding cylinder 3248. The fixed sliding cylinder 3248 is also slidably connected to the fixed frame 31 for guiding. The structure is simple and has strong practicability.

[0082] In some embodiments, the above-mentioned lifting slide 321 may adopt the structure as shown in Figure 3 and Figure 6 . See Figure 3 and Figure 6 Each lifting slide 321 has a contact end surface at the end close to another lifting slide 321, and each contact end surface is provided with a planar thrust bearing 3249 for the corresponding clamping claw 323 to contact.

[0083] The plane thrust bearing 3249 has two rings, one of which is fixed on the lifting slide 321, and the other ring can be contacted by the clamping claw 323 after the clamping claw 323 is close to the lifting slide 321. At this time, the reverse force of the clamping pipe element 40 can be transmitted to the lifting slide 321, and it can also facilitate the rotation of the clamping claw 323. In addition, this structure can also increase the contact surface and balance the force. In addition, it should be noted that the distance between each clamping claw 323 and the corresponding plane thrust bearing 3249 is only slightly larger than the thickness of the prism block 3242, so as to ensure that after the clamping claw 323 contacts the plane thrust bearing 3249, the prism block 3242 can be separated from the mounting groove.

[0084] See also Figure 7 As another embodiment of the pipeline element performance test equipment provided by the present invention, it involves a pipeline element 40 and a part of a right-angle elbow pipe, that is, the axes of the two connecting ends of the pipeline element 40 are vertically arranged. At this time, the second support member 13 can be replaced to increase the height of the clamping mechanism, and at the same time, the first support member 12 in one of the connecting mechanisms 20 is replaced to make the height of the fixed cylinder 21 adapt to the clamping mechanism. The fixed cylinder 21 in another connecting mechanism 20 is rotated 90° and then fixed on the first support member 12, that is, the axes of the two joints 24 are vertically arranged to adapt to the right-angle elbow pipe. Of course, the angle of the fixed cylinder 21 in one of the connecting mechanisms 20 can be adjusted to adapt to elbow pipes of other angles, which will not be repeated here.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
