Description

Technical Field

[0001] This utility model relates to the field of composite pipe pressure testing technology, and in particular to a pipe uniform pressure application device based on water pressure composite. Background Technology

[0002] After production, composite pipes must undergo rigorous pressure testing to ensure their performance and quality reliability. Therefore, pressure testing equipment is crucial in this process. This equipment not only shapes the pipes but also plays a key role in testing and quality control. Utilizing the uniform distribution of water pressure, the equipment applies even pressure to the pipes, ensuring uniform stress distribution during shaping or testing. This process not only effectively improves the shaping accuracy of the pipes but also significantly enhances their overall quality, ensuring that the final product meets stringent usage standards and high customer requirements.

[0003] The main problems in hydraulic pressure testing of composite pipes lie in the sealing effect and stability at both ends. These issues lead to leaks at both ends during testing, negatively impacting the results. This not only affects the accuracy of the test but may also cause potential problems during subsequent use. Therefore, there is an urgent need for a hydraulic pressure composite pipe uniform pressure application device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pipe uniform pressure application device based on water pressure composite.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pipe pressure uniform pressure application device based on water pressure composite includes a base, a fixed frame fixed to the top of the base, a sealing mechanism for sealing both ends of the composite pipe inside the fixed frame, and a testing mechanism for water pressure testing of the composite pipe at the top of the fixed frame. The sealing mechanism includes two sealing columns, each with an anti-slip strip on one end of its outer wall and a sealing gasket at the center of its outer wall. The other end of the sealing column has a threaded groove and a retaining ring fixed thereon. Rotating cylinders are located on the opposite sides of the two sealing columns, with movable grooves on their inner walls and the retaining rings inside the movable grooves. The adjacent sides of the two rotating cylinders are arc-shaped, and the inner wall of the rotating cylinder near the sealing gasket has threads that match the threaded grooves. By rotating the rotating cylinders and gradually pressing the sealing gasket, both ends of the composite pipe can be sealed.

[0006] Preferably, a pressure sensor is mounted on the top of the two sealing columns that are close to each other.

[0007] Preferably, L-shaped connecting brackets are fixed to both ends of the top of the base. The two L-shaped connecting brackets are fixed to the same fixed frame on their adjacent sides. The fixed frame has two fixing blocks inside. One of the fixing blocks is fixed to one side of the inner wall of the fixed frame. The other fixing block is rotatably connected to a second threaded rod on one side. The inner wall of the fixed frame has a threaded hole that matches the second threaded rod. Two guide rods are fixed to one side of the fixing block. The inner wall of the fixed frame has a hole for the guide rods to communicate with each other. The two fixing blocks can limit the rotation of the cylinder and prevent the sealing column from being pushed out by excessive water pressure.

[0008] Preferably, the testing mechanism includes a water storage tank fixed to the top of a frame, with water pumps installed at both ends of the top of the frame, and the inlet ends of the two water pumps connected to the bottom of both ends of the inner wall of the water storage tank via conduits. A pressure machine is installed at both ends of the top of the frame, and the outlet end of the water pump is connected to a connecting delivery hose.

[0009] Preferably, the other end of the delivery hose passes through the rotating cylinder and the sealing column.

[0010] Preferably, the base has fixed plates on both sides of its top end, and clamping blocks are provided on the side of the two fixed plates that are close to each other. One clamping block is fixedly connected to one side of the fixed plate by a fixed rod, and a first threaded rod is rotatably connected to one side of the other clamping block. Threaded grooves that are adapted to the first threaded rod are opened on the top of both sides of the other fixed plate. Two limiting rods are fixed on one side of the clamping block, and slots for the limiting rods to pass through are opened on both sides of one of the fixed plates.

[0011] Preferably, a water tank is installed on the top of the base, and a control panel is installed on one side of the top of the mounting bracket.

[0012] The beneficial effects of this utility model are as follows: 1. Due to the adoption of a sealing mechanism, two sealing posts are inserted into both ends of the inner wall of the composite pipe. Anti-slip strips are then used to prevent the sealing posts from slipping. A sealing gasket is then placed between the composite pipe and the sealing posts. By rotating the rotating cylinder and adapting it to the threaded groove, the sealing gasket is gradually squeezed, fully filling the space between the sealing posts and the composite pipe. This improves the stability and sealing of the composite pipe during water pressure testing, and increases the accuracy of the testing. The operation is simple, highly practical, and convenient for pressure testing of composite pipes. Two pressure sensors can evenly apply pressure to the inside of the composite pipe, making it easy to observe the internal pressure. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A pipe uniform pressure application device based on water pressure composite includes a base 1, a fixing frame 101 fixed on the top of the base 1, a sealing mechanism for sealing the two ends of the composite pipe at both ends inside the fixing frame 101, and a testing mechanism for water pressure testing of the composite pipe at the top of the fixing frame 101. The sealing mechanism includes two sealing columns 404. Each sealing column 404 has an anti-slip strip 406 at one end of its outer wall and a sealing gasket 407 at the center of its outer wall. The other end of the sealing column 404 has a threaded groove 409 on its outer wall and a retaining ring 408 fixed to the other end. The two sealing columns 404 have rotating cylinders 410 on their opposite sides. The inner wall of the rotating cylinder 410 has a movable groove 411, and the retaining ring 408 is located inside the movable groove 411. The two rotating cylinders 410 have arc-shaped surfaces on their adjacent sides. The inner wall of the rotating cylinder 410 near the sealing gasket 407 has a thread that matches the threaded groove 409. By rotating the rotating cylinder 410 and gradually squeezing the sealing gasket 407, the two ends of the composite pipe can be sealed.

[0017] In this invention, a pressure sensor 405 is installed on the top of the side of the two sealing pillars 404 that are close to each other.

[0018] In this utility model, L-shaped connecting brackets 4 are fixed on both sides of the top of the base 1. The same fixing frame 401 is fixed on the side of the two L-shaped connecting brackets 4 that are close to each other. The fixing frame 401 has two fixing blocks 402 inside. One fixing block 402 is fixed to one side of the inner wall of the fixing frame 401. The other fixing block 402 is rotatably connected to one side of the second threaded rod 403. The inner wall of the fixing frame 401 has a threaded hole that matches the second threaded rod 403. Two guide rods are fixed on one side of the fixing block 402. The inner wall of the fixing frame 401 has a hole for the guide rods to communicate. The two fixing blocks 402 can limit the rotation cylinder 410 to prevent the sealing column 404 from being pushed out by excessive water pressure.

[0019] In this utility model, the testing mechanism includes a water storage tank 2 fixed on the top of a fixed frame 101. Water pumps 201 are installed at both ends of the top of the fixed frame 101, and the inlet ends of the two water pumps 201 are connected to the bottom ends of the inner wall of the water storage tank 2 through pipes. A pressurizer 202 is installed at both ends of the top of the fixed frame 101. The outlet end of the water pump 201 is connected to a conveying hose 203. The pressurizer 202 is connected to a gas storage tank through a pipe. The gas storage tank is connected to the outlet end of the water pump 201 and the conveying hose 203 through a pipe.

[0020] In this invention, the other end of the conveying hose 203 passes through the rotating cylinder 410 and the sealing column 404.

[0021] In this utility model, both ends of the top of the base 1 are fixed with fixing plates 3, and the sides of the two fixing plates 3 that are close to each other are provided with clamping blocks 301. One clamping block 301 is fixedly connected to one side of the fixing plate 3 by a fixing rod, and the other clamping block 301 is rotatably connected to one side of the first threaded rod 302. The top of both sides of the other fixing plate 3 is provided with threaded grooves that are adapted to the first threaded rod 302. Two limiting rods 303 are fixed on one side of the clamping block 301. The two sides of one fixing plate 3 are provided with slots for the limiting rods 303 to pass through. The two clamping blocks 301 can clamp and fix the composite pipe and provide its stability.

[0022] In this utility model, a water tank 102 is installed on the top of the base 1, and a control panel 103 is installed on one side of the top of the fixing bracket 101.

[0023] Working principle: In use, firstly, place both ends of the composite pipe between the clamping blocks 301. Then, rotate the first threaded rod 302, which pushes the clamping blocks 301, causing them to contact the outer wall of the composite pipe. Next, push the composite pipe towards another clamping block 301. The two clamping blocks 301 then clamp and fix the composite pipe, providing stability for water pressure testing. Then, insert the two sealing posts 404 into the inlet and outlet of the composite pipe respectively. Through compression, the sealing gasket 407 is positioned between the composite pipe and the sealing posts 404. At this time, the anti-slip strip 406 provides simple anti-slip for the sealing posts 404. Then, rotate the rotating cylinder 410, which causes the thread to engage with the threaded groove 409 and causes the arc-shaped surface at the other end of the rotating cylinder 410 to compress the sealing gasket 407. The number of rotations of the cylinder 410 determines the degree to which the sealing gasket 407 is compressed, ensuring it fully fills the space between the composite pipe and the sealing column 404, thus achieving a seal. Then, by rotating the second threaded rod 403, the fixing block 402 is brought closer to the outer wall of the rotating cylinder 410, and the rotating cylinder 410 is fixed by the two fixing blocks 402 to prevent the sealing column 404 from being ejected due to excessive water pressure. Next, the water pump 201 is run to pump water from the inside of the water storage tank 2, and the pressure is increased by the pressurizer 202. Water is then delivered to the inside of the composite pipe through the other end of the delivery hose 203. The pressure sensor 405 transmits the signal to the control panel 103, and the pressure value is simultaneously displayed on the screen. This achieves the effect of pressure detection on the composite pipe, and the data from the pressure sensor 405 ensures uniform pressure application.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
