Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting testing equipment, and in particular to a pipe fitting pressure testing machine for simultaneous pressure testing of multiple pipe fittings. Background Technology

[0002] During the research and development of pipe fittings, it is necessary to test the internal pressure bearing capacity of the pipe fittings. The main testing method in the existing technology is to use a pipe fitting pressure testing machine to inject water into the pipe fitting and then squeeze the water to increase the internal water pressure of the pipe fitting, and to test the steel pipe for leakage points on the inner wall of the steel pipe, while testing the maximum pressure bearing capacity of the pipe fitting.

[0003] For example, Chinese Patent Publication No. CN221882956U discloses a pipeline pressure testing device, which includes a first support member, a second support member, a jack, and a pressure testing component. The first support member includes a first back plate and a first bottom plate that are perpendicular to each other. The second support member includes a second back plate and a second bottom plate that are perpendicular to each other. The second bottom plate is disposed on the first bottom plate. The second back plate is disposed opposite to the first back plate. A first support rod is provided between the first back plate and the second back plate. A second support rod is provided between the second back plate and the second bottom plate. The jack is disposed on the side of the second back plate away from the first support rod. The pressure testing component is disposed on the top plate of the jack.

[0004] For example, Chinese Patent Publication No. CN211122343U discloses a large stainless steel pipe fitting testing machine, which includes a support plate. The support plate has a groove inside, and two sliders are slidably connected inside the groove. A first support frame is fixedly connected to the top of one slider. A nut is welded inside the first support frame, and a screw is threaded into the nut. A rubber plug is fixedly connected to the bottom end of the screw. In this large stainless steel pipe fitting testing machine, the rubber plug connected to the first support is kept horizontal with the pipe opening. Twisting the nut causes the screw to move the rubber plug into the interior of the steel pipe, thus maintaining a tight seal.

[0005] The pipe pressure testing devices mentioned above can only test a single pipe at a time. When testing multiple pipes, each pipe needs to be clamped one by one before testing, which requires repeated operations. This is cumbersome and labor-intensive, affecting the overall testing efficiency.

[0006] Therefore, it is necessary to provide a pipe fitting pressure testing machine that can simultaneously test multiple pipe fittings to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to provide a pipe fitting pressure testing machine for simultaneous pressure testing of multiple pipe fittings, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a pipe fitting pressure testing machine for simultaneous pressure testing of multiple pipe fittings, comprising a support plate, a fixed seat fixed on the top side of the support plate, an inner groove extending through the interior of the fixed seat, a plurality of symmetrically distributed arc-shaped grooves b at the bottom of the inner groove, a multi-clamp assembly that cooperates with the arc-shaped grooves b to fix multiple pipes inside the inner groove, two end pressure plates on the top of the support plate, the two end pressure plates symmetrically distributed on both sides of the fixed seat, and rubber pads b fixedly attached to the sides of the two end pressure plates that are close to each other, an adjustment assembly for driving the two end pressure plates to move synchronously in opposite directions on one side of the fixed seat, a plurality of equally spaced diversion pipes fixed inside one of the end pressure plates, the ports of the diversion pipes extending out of the side of the end pressure plate, the ends of the plurality of diversion pipes away from the end pressure plate being connected to a main flow pipe, and an inlet pipe connected to the main flow pipe.

[0009] As a further embodiment of this utility model, the adjustment assembly includes a bracket plate fixed to the top surface of the support plate. Two bracket plates are provided and symmetrically distributed. A double-helical threaded rod is rotatably connected between the two bracket plates. A servo motor is fixed on the side of one of the bracket plates. The output end of the servo motor is fixed to one end of the double-helical threaded rod. A protruding plate is fixed to one end of each of the two end pressure plates. A nut sleeve that is threadedly connected to the double-helical threaded rod is fixed inside the two protruding plates.

[0010] As a further embodiment of this utility model, a guide groove is fixed on the top surface of the support plate and arranged along the length direction of the support plate, and a protruding rod that slides with the guide groove is fixed at the bottom end of the protruding plate.

[0011] As a further embodiment of this utility model, the multi-clamp assembly includes a pressure plate disposed inside the inner groove and adjustable in movement. The bottom surface of the pressure plate is provided with a plurality of arc-shaped grooves a, and the plurality of arc-shaped grooves a and the plurality of arc-shaped grooves b are provided in a one-to-one correspondence.

[0012] As a further embodiment of this utility model, a threaded rod is internally threaded to the top side wall of the fixed seat, the bottom end of the threaded rod is rotatably connected to the pressure plate, both ends of the pressure plate are fixed with end plates, and a sliding groove adapted to slide with the end plates is provided on the inner side wall of the fixed seat.

[0013] As a further embodiment of this utility model, the top of the threaded rod has a handle rod, and a rubber sleeve is fitted onto the surface of the handle rod.

[0014] As a further embodiment of this utility model, rubber pads a and c are respectively attached and fixed to the sides of the arc groove a and arc groove b, and a plurality of equidistant protrusions are provided on the outer surfaces of the rubber pads a and c.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using a multi-clamp assembly, multiple pipe fittings located inside the inner groove are simultaneously clamped and limited, thereby fixing multiple pipes at the same time. This facilitates pressure testing of multiple pipe fittings, eliminating the need to clamp each pipe fitting individually. The operation is convenient and effectively improves the efficiency of clamping multiple pipe fittings. At the same time, it ensures that the pipe fittings are fully and comprehensively fixed, improving their stability.

[0017] 2. The set adjustment component drives the two end pressure plates to move closer to each other, so that the two end pressure plates press against the two ends of the pipe fitting, causing the rubber pad b to undergo elastic deformation. Thus, the end pressure plates and rubber pad b seal the ends of the pipe fitting. At this time, the diversion pipe is located at the center of the pipe fitting end and is connected to the inside of the pipe fitting. Water is synchronously diverted and delivered to the inside of multiple pipe fittings through the inlet pipe and multiple diversion pipes.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-5This utility model provides a pipe fitting pressure testing machine for simultaneous pressure testing of multiple pipe fittings, including a support plate 4, a fixing seat 3 fixed on the top side of the support plate 4, an inner groove 14 extending through the inside of the fixing seat 3, a plurality of equally spaced arc-shaped grooves b7 provided at the bottom of the inner groove 14, a multi-clamp assembly 2 provided inside the inner groove 14 to fix multiple pipes in cooperation with the arc-shaped grooves b7, two end pressure plates 5 provided on the top of the support plate 4, the two end pressure plates 5 being symmetrically distributed on both sides of the fixing seat 3, and rubber pads b8 being fixedly attached to the sides of the two end pressure plates 5 that are close to each other, and an adjustment assembly 1 provided on one side of the fixing seat 3 to drive the two end pressure plates 5 to move synchronously in opposite directions, a plurality of equally spaced diversion pipes 10 fixed inside one of the end pressure plates 5. The port of the diversion pipe 10 extends outward from the side of the end pressure plate 5. The ends of multiple diversion pipes 10 away from the end pressure plate 5 are connected to the main pipe 11, and the main pipe 11 is connected to the inlet pipe 9. A pipe fitting pressure testing machine for simultaneous pressure testing of multiple pipe fittings includes a support plate 4. A fixing seat 3 is fixed on the top side of the support plate 4. An inner groove 14 is opened inside the fixing seat 3. Multiple symmetrically distributed arc grooves b7 are provided at the bottom of the inner groove 14. A multi-clamp assembly 2 is provided inside the inner groove 14 to fix multiple pipes in cooperation with the arc grooves b7. Two end pressure plates 5 are provided on the top of the support plate 4. The two end pressure plates 5 are symmetrically distributed on both sides of the fixing seat 3. An adjustment assembly 1 is provided on one side of the fixing seat 3 to drive the two end pressure plates 5 to move synchronously in opposite directions. Multiple equally spaced branch pipes 10 are fixed inside the pressure plate 5. The ends of the branch pipes 10 extend out of the side of the pressure plate 5. The ends of the multiple branch pipes 10 away from the pressure plate 5 are connected to the main flow pipe 11, and the main flow pipe 11 is connected to the inlet pipe 9. Multiple symmetrically distributed support rods 6 are fixed on the bottom side of the support plate 4. Multiple pipe fittings to be tested are inserted into the inner groove 14 and placed into multiple arc-shaped grooves b7. The multi-clamp assembly 2 is used to simultaneously clamp and limit the multiple pipe fittings inside the inner groove 14, thereby simultaneously fixing the multiple pipes. This facilitates pressure testing of multiple pipe fittings, eliminates the need to clamp each pipe fitting individually, and improves the efficiency of clamping multiple pipe fittings. At the same time, it ensures that the pipe fittings are fully clamped. Comprehensive fixation enhances the stability of the pipe fittings. After multiple pipe fittings are clamped and fixed, the adjustment component 1 drives the two end pressure plates 5 to move closer to each other, thereby pressing the two ends of the pipe fittings together. This causes the rubber pad b8 to undergo elastic deformation, thus sealing the ends of the pipe fittings through the end pressure plates 5 and the rubber pad b8. At this time, the diversion pipe 10 is located at the center of the pipe fitting end and is connected to the inside of the pipe fitting. The water inlet pipe 9 is connected to an external water pump, and water is synchronously diverted and delivered to the inside of multiple pipe fittings through the water inlet pipe 9 and multiple diversion pipes 10. This gives the inside of the pipe fittings a certain hydraulic pressure, thereby checking whether there are any leaks on the inner wall of the pipe fittings. Multiple pipe fittings can be pressure tested simultaneously at one time, effectively improving the efficiency of pressure testing of multiple pipe fittings.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the adjustment assembly 1 includes a support plate 106 fixed to the top surface of the support plate 4. Two support plates 106 are provided and symmetrically distributed. A double-threaded rod 101 is rotatably connected between the two support plates 106. A servo motor 107 is fixed to the side of one of the support plates 106. The output end of the servo motor 107 is fixed to one end of the double-threaded rod 101. A protruding plate 104 is fixed to one end of each of the two end pressure plates 5. A nut sleeve 105, threadedly connected to the double-threaded rod 101, is fixed inside the interior of each protruding plate 104. A guide groove 102 arranged along the length of the support plate 4 is fixed to the top surface of the support plate 4. A [missing information - likely a typo, should be inserted here] is fixed to the bottom end of the protruding plate 104. The convex rod 103 slides in cooperation with the guide groove 102; after multiple pipe fittings are clamped and fixed, the servo motor 107 is started to work. The output end of the servo motor 107 drives the double-threaded rod 101 to rotate. The double-threaded rod 101 cooperates with the nut sleeve 105, and the convex rod 103 cooperates with the guide groove 102 to move the convex plate 104 for guidance and limitation. Thus, the rotating double-threaded rod 101 drives the two convex plates 104 to move closer to each other, and then drives the two end pressure plates 5 to move closer to each other. This causes the two end pressure plates 5 to press on the two ends of the pipe fitting, causing the rubber gasket b8 to undergo elastic deformation. Thus, the ends of the pipe fitting are sealed by the end pressure plates 5 and the rubber gasket b8.

[0029] Further as Figure 1 , Figure 4 and Figure 5As shown, it is worth noting that the multi-clamp assembly 2 includes a movable and adjustable pressure plate 201 disposed inside the inner groove 14. Multiple arc-shaped grooves a205 are provided on the bottom surface of the pressure plate 201, and these grooves a205 correspond one-to-one with multiple arc-shaped grooves b7. A threaded rod 202 is threadedly connected to the top side wall of the fixing seat 3. The bottom end of the threaded rod 202 is rotatably connected to the pressure plate 201. End plates 207 are fixed to both ends of the pressure plate 201. A sliding groove 208 is provided on the inner side wall of the fixing seat 3 to slide and adapt to the end plates 207. Multiple pipe fittings to be tested are inserted into the inner groove 14 and placed into the multiple arc-shaped grooves b7 respectively. By rotating the threaded rod 202 downwards, the threaded rod 202 drives... The pressure plate 201 is adjusted downwards so that the arc groove a205 at the bottom of the pressure plate 201 contacts the surface of the pipe fitting. This allows the pressure plate 201 to simultaneously clamp and limit the multiple pipe fittings located inside the inner groove 14, thus fixing the multiple pipes simultaneously. This facilitates pressure testing of multiple pipe fittings, eliminating the need to clamp each pipe fitting individually. The operation is convenient and effectively improves the efficiency of clamping multiple pipe fittings. At the same time, it ensures that the pipe fittings are fully and comprehensively fixed, improving their stability. The pressure plate 201 drives the end plate 207 to move within the slide groove 208. The end plate 207 and the slide groove 208 work together to guide and limit the movement of the pressure plate 201, improving the stability of the pressure plate 201's movement adjustment.

[0030] This solution includes the following working process: Multiple pipe fittings to be tested are inserted into the inner groove 14 and placed into multiple arc-shaped grooves b7 respectively. By turning the threaded rod 202 downward, the threaded rod 202 drives the pressure plate 201 to move downward, so that the arc-shaped groove a205 at the bottom of the pressure plate 201 contacts the surface of the pipe fitting. Thus, the pressure plate 201 clamps and limits the multiple pipe fittings located inside the inner groove 14 simultaneously, thereby fixing the multiple pipes synchronously. After the multiple pipe fittings are clamped and fixed, the output end of the servo motor 107 drives the double-direction threaded rod 101 to rotate. The double-direction threaded rod 101 cooperates with the nut sleeve 105, and through the convex rod 103 and the guide groove 102... The guide plate 104 is moved and limited by the rotating double-threaded rod 101, which drives the two protruding plates 104 to move closer to each other. This, in turn, drives the two end pressure plates 5 to move closer to each other, so that the two end pressure plates 5 press against the two ends of the pipe fitting. This causes the rubber gasket b8 to undergo elastic deformation, thereby sealing the ends of the pipe fitting through the end pressure plates 5 and the rubber gasket b8. At this time, the diversion pipe 10 is located at the center of the pipe fitting end and is connected to the inside of the pipe fitting. Water is synchronously diverted and delivered to the inside of multiple pipe fittings through the water inlet pipe 9 and multiple diversion pipes 10, thereby checking whether there are any leaks on the inner wall of the pipe fitting. Multiple pipe fittings can be pressure tested simultaneously at one time.

[0031] Further as Figure 4 and Figure 5As shown, it is worth noting that the top of the threaded rod 202 has a handle 203, and a rubber sleeve 204 is fitted onto the surface of the handle 203. In actual operation, the threaded rod 202 can be easily rotated by the handle 203. The handle 203 has a long lever arm, making operation convenient and labor-saving.

[0032] Further as Figure 4 and Figure 5 As shown, it is worth noting that rubber pads a206 and c13 are respectively attached and fixed to the sides of the arc groove a205 and the arc groove b7. Multiple equidistant protrusions are provided on the outer surfaces of the rubber pads a206 and c13. In actual operation, the rubber pads a206 and c13 increase the friction of the pressure plate 201 in clamping the pipe fitting, thereby further improving the clamping stability of the pipe fitting.

[0033] In summary: The multi-clamp assembly 2 synchronously clamps and limits the multiple pipe fittings located inside the inner groove 14, thereby simultaneously fixing the multiple pipes. This facilitates pressure testing of multiple pipe fittings, eliminating the need to clamp each pipe fitting individually. The operation is convenient and effectively improves the efficiency of clamping multiple pipe fittings, while ensuring thorough and comprehensive fixation and enhancing pipe stability. After the multiple pipe fittings are clamped and fixed, the adjusting assembly 1 moves the two end pressure plates 5 closer together, causing the two end pressure plates 5 to press against the two ends of the pipe fittings. This causes the rubber pad b8 to undergo elastic deformation, thereby sealing the pipe end through the end pressure plate 5 and the rubber pad b8. At this time, the diversion pipe 10 is located at the center of the pipe end and is connected to the inside of the pipe. The water inlet pipe 9 is connected to a water pump, and water is synchronously diverted and delivered to the inside of multiple pipes through the water inlet pipe 9 and multiple diversion pipes 10, thereby giving the inside of the pipe a certain hydraulic pressure, and thus checking whether there are any leaks on the inner wall of the pipe. Multiple pipes can be pressure tested simultaneously at one time, effectively improving the pressure testing efficiency of multiple pipes.

[0034] The servo motor 107 can be purchased from the market. The servo motor 107 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
