Description

Technical Field

[0001] The present invention belongs to the technical field of valve detection, and in particular relates to a valve pressure resistance performance detection device and a detection method. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium.

[0003] In some special cases, valves will be used in high-pressure pipelines, so there are high requirements for the valve to withstand pressure. Although the main body of the valve is mostly integrally formed, the valve core and handle are assembled. When the pressure in the pipeline is high, these parts are prone to leakage, so the pressure resistance of the valve needs to be tested.

[0004] In the existing detection device, after the valve is fixed, high-pressure water flow will be injected into the constructed pipeline, and the pressure data will be analyzed by special instruments. However, at this time, the state of the valve is generally open or closed, and its state cannot be changed. As we all know, the parts related to the valve core on the valve are prone to leakage. If the state of the valve core cannot be changed, this detection lacks reference value for the valve under actual working conditions. Therefore, a valve pressure resistance performance detection device and detection method are proposed to solve the above problems. Summary of the invention

One end of the hydraulic telescopic component is fixedly connected to a push plate that is slidably set on the two slide rails. A circular hole is opened on the top of the push plate, and the second straight pipe is located in the circular hole.

[0033] In order to make the purpose, technical solution and advantages of 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.

[0034] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a valve pressure resistance performance detection device provided by an embodiment of the present invention includes a device platform 1, a rectangular installation position is opened in the middle of the device platform 1, and further includes:

[0036] The conveying assembly 2 is located on the device platform 1. The conveying assembly 2 includes guide rail frames 201 located on both sides of the rectangular installation position. The two guide rail frames 201 are arranged in parallel. A moving seat 202 is slidably arranged on the guide rail frame 201. The top of the moving seat 202 is fixedly connected with a support seat 203. When the moving seats 202 on both sides drive the valve to move horizontally, the flanges at both ends of the valve are located on the support seat 203;

[0037] A fastening connection assembly, wherein the fastening connection assembly comprises a mounting frame 3 located on both sides of the device platform 1, a guide rail frame 201 located between the mounting frame 3 and the rectangular mounting position, a pipe docking structure 4 capable of moving in a direction perpendicular to the guide rail frame 201 is provided on the mounting frame 3, a hydraulic driving member 5 for driving the pipe docking structure 4 to move is also provided on the mounting frame 3, an output end of the pipe docking structure 4 is a pressure plate 401 arranged toward the guide rail frame 201 and corresponding to the position of the support seat 203, a sealing gasket 402 is provided on the pressure plate 401, the pressure plate 401 and the sealing gasket 402 cooperate with the flanges at both ends of the valve, and an input end of the pipe docking structure 4 is connected to an external water supply pipeline;

[0038] The debugging component 6 includes a first power box 601 located in a rectangular installation position, the output end of the first power box 601 is a rotating shaft 602 located at the top of the first power box 601, and a chuck 603 is fixedly connected to the rotating shaft 602. The bottom of the device platform 1 is fixedly connected to a frame 604, and the frame 604 is provided with a lifting drive 605 for driving the first power box 601 to move in a vertical direction. The lifting drive 605 can be in the form of hydraulic telescopic, and of course, it can also be in the form of electric telescopic.

[0039] In one embodiment of the present invention, the detection device uses a hydraulic drive 5 to drive the pressure plate 401 and the sealing gasket 402 to connect with the flanges at both ends of the valve, simulating a real valve usage scenario, so that the valve detection is more meaningful for reference; after the valve is tightened by the pressure plates 401 on both sides, the valve as a whole is in a fixed state. When performing a pressure resistance test, the lifting drive 605 can drive the chuck 603 to move up and contact the valve handle. This orientation of the valve is due to the use of the support seats 203 on both sides to transfer the valve. Due to the uneven center of gravity of the valve as a whole, the valve handle can automatically flip to a downward state, so that the chuck 603 can control the rotation of the handle, so that the valve can switch between the open and closed states, so that the pressure resistance test can be performed in different states of the valve, which can not only detect the sealing of the valve core component of the valve, but also ensure the integrity of the pressure resistance test data.

[0040] In one embodiment of the present invention, it should be noted that, Figure 4As shown in the figure, the moving seat 202 includes a frame body 2021 arranged around the guide rail frame 2021. A roller in contact with the guide rail frame 2021 is arranged inside the frame body 2021. A second power box body 2022 for driving the roller to rotate is fixedly connected to the bottom of the frame body 2021. The support seat 203 includes an arc-shaped block 2301 fixedly connected to the top of the frame body 2021. An installation groove is provided on the arc-shaped block 2301 along the length direction of the guide rail frame 2021. A plurality of support rollers 2302 for contacting the flange side of the valve are rotatably arranged in the installation groove. Generally, the overall valve will present a character "pin" shape, that is, the two ends of the pipeline of the valve (flange ends) and the handle part of the valve form a character "pin" shape. When the flange ends are placed on the two support seats 203, the handle part will naturally rotate to the vertically downward state under the action of gravity at this time. Due to the existence of the support rollers 2302, the automatic adjustment of the valve's own orientation will be smoother.

[0041] As Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, the pipeline docking structure 4 includes a vertical frame 403 fixedly connected to the mounting frame 3. A ring body 404 is fixedly connected to the top of the vertical frame 403. A first straight pipe 405 is arranged inside the ring body 404. The pressing disc 401 is fixedly connected to one end of the first straight pipe 405 facing the guide rail frame 2021. A plurality of uniformly arranged positioning pins 406 are fixedly connected to one side of the pressing disc 401 facing the support seat 203. The sealing gasket 402 is arranged on the pressing disc 401 through the positioning pins 406. The other end of the first straight pipe 405 is provided with a second straight pipe 408 connected through a flange disc 407. The second straight pipe 408 is connected to an external water supply pipeline. Two sliding rails 7 arranged at intervals are fixedly connected to the mounting frame 3. The hydraulic driving member 5 includes a hydraulic telescopic member 501 horizontally fixedly connected to the mounting frame 3 and located between the sliding rails 7. One end of the hydraulic telescopic member 501 is fixedly connected to a push plate 502 slidably arranged on the two sliding rails 7. A round hole position 503 is opened at the top of the push plate 502. The second straight pipe 408 is located in the round hole position 503. When the hydraulic telescopic member 501 drives the push plate 502 to move, the side surface of the push plate 502 contacts the flange disc 407.

[0042] In one case of this embodiment, a plurality of elastic reset rods 8 are fixedly connected to one side of the ring body 404 facing the pressure plate 401. The plurality of elastic reset rods 8 are evenly arranged about the first straight tube 405. The other end of the elastic reset rod 8 is connected to the pressure plate 401. By utilizing the characteristic that bolt holes are reserved on the flange, a positioning pin 406 is provided on the pressure plate 401. When the hydraulic telescopic member 501 drives the first straight tube 405 and the second straight tube 408 to move horizontally through the push plate 502, the positioning pin 406 is inserted into the bolt holes of the flanges at both ends of the valve. , so that the pressure plate 401 and the flange of the valve are automatically docked, so that the pressure plate 401, the flange and the sealing ring are combined together. In this way, the valve docking can be made more accurate. After the detection is completed, the hydraulic telescopic member 501 will drive the push plate 502 to reset. At this time, the elastic reset rod 8 in the extended state will pull the pressure plate 401, so that the pressure plate 401, the first straight pipe 405 and the second straight pipe 408 are reset. This method can keep the push plate 502 and the second straight pipe 408 in a disengaged state, and there is no need to fix the two.

[0043] like Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, a circumferential groove 9 is opened in the ring body 404, and a plurality of driving rollers 10 in contact with the surface of the first straight tube 405 are rotatably arranged in the circumferential groove 9, and a third power box 11 is arranged on one side of the outside of the ring body 404, and the third power box 11 is used to drive one of the driving rollers 10 in the ring body 404 to rotate, and an annular limit groove 12 is opened on the side of the pressure plate 401 facing the ring body 404, and a plurality of limit blocks 13 fixedly connected to one end of the elastic reset rod 8 are arranged in the annular limit groove 12.

[0044] In one case of the present embodiment, the flange is fixed to both ends of the valve by welding, which results in that the position of the bolt holes on the flange is not constant. The presence of the support roller 2302 can ensure that the handle of the valve faces downward, but cannot ensure that the bolt holes on the flange of the valve are fixed after rotation. Therefore, the second power box 2022 can be used to control the rotation of the drive roller 10, so that the first straight pipe 405, the second straight pipe 408 and the pressure plate 401 are rotated, so that the position of the positioning pin 406 can be adjusted so that it can be accurately docked with the flanges at both ends of the valve. Of course, this rotation is not a large-angle rotation, and only slight adjustments are required. Therefore, the second straight pipe 408 will be connected to the water pipe of the water supply pipeline, so there will be no situation where it cannot rotate. The above working processes are all based on the situation that the flange positions at both ends of the valve are known. Therefore, industrial cameras can be set on both sides of the guide frame 201 on the device platform 1, and the flange end faces can be photographed by the industrial cameras. The image recognition and analysis technology is used to identify the position of the bolt holes on the flange. When the positions of the bolt holes on the flanges at both ends of the valve are known, the position adjustment of the positioning pin 406 on the pressure plate 401 can be carried out. Because of the presence of the limiting block 13 and the annular limiting groove 12, it can be ensured that the connection between the elastic reset rod 8 and the pressure plate 401 will not be separated due to rotation. It should be noted that since the pressure plate 401 presses the sealing gasket 402 on the flange of the valve, when the detection is completed, the pressure plate 401 will be separated from the flange of the valve. At this time, it is easy for the sealing gasket 402 to be attached to the flange of the valve and cannot be separated. At this time, the industrial camera mentioned in the above text can be used to monitor the separation and reset state of the positioning pin 406. Of course, this requires the cooperation of the hydraulic telescopic member 501. When the positioning pin 406 is separated from the flange of the valve, the positioning pin 406 is only in contact with the pressure plate 401 and the sealing gasket 402. At this time, controlling the rotation of the pressure plate 401 can make the sealing gasket 402 rotate, and the sealing gasket 402 can be separated in this way.

[0045] like Figure 8 As shown, as a preferred embodiment of the present invention, the chuck 603 includes a disk body 6031 fixedly connected to the rotating shaft 602, and a plurality of evenly distributed inclined blocks 6032 are fixedly connected to the disk body 6031. When the lifting drive member 605 drives the first power box 601 to move toward the top, the inclined block 6032 is used to contact the handle of the valve.

[0046] In one case of the present embodiment, motors may be provided in the first power box body 601, the second power box body 2022 and the third power box body 11, and the corresponding mechanisms are driven to operate by the motors. When the valve is pressed and fixed by the pressure plates 401 on both sides, due to the presence of the positioning pin 406, when the inclined surface block 6032 contacts the valve handle, the valve as a whole will not deflect or offset, so that the inclined surface block 6032 is directly pressed against the valve handle. At this time, the rotation of the disk body 6031 will drive the valve handle to rotate, thereby realizing the opening or closing of the valve.

[0047] The embodiment of the present invention further provides a method for detecting the pressure resistance performance of a valve, and the method for detecting the pressure resistance performance of a valve comprises the following steps:

[0048] Step 1: Place both ends of the valve to be tested on the support seat 203. Due to the force of gravity, the handle of the valve will automatically deflect to a downward state, and the moving seat 202 drives the valve to move from one section of the guide frame 201 to the specified position;

[0049] Step 2: The third power box 11 drives the driving roller 10 to rotate and control the positioning pin 406 on the pressure plate 401 to adjust the position. When the positioning pin 406 on the pressure plate 401 corresponds to the flanges at both ends of the valve, the hydraulic telescopic member 501 drives the pressure plate 401 to move horizontally and dock with the flanges at both ends of the valve.

[0050] Step 3: The water supply pipeline delivers high-pressure water to the valve through the first straight pipe 405 and the second straight pipe 408 for pressure resistance testing. During the pressure resistance testing, the lifting drive 605 drives the chuck 603 to move up and contact the valve handle, and the first power box 601 drives the chuck 603 to rotate so that the valve switches between the open and closed states.

[0051] Step 4: After the detection is completed, the chuck 603 and the hydraulic telescopic member 501 are reset, and the elastic reset rod 8 is used to reset the pressure plate 401, and the moving seat 202 drives the tested valve to move to the other end of the guide rail frame 201.

[0052] In one case of the present embodiment, after the valve is tightened by the pressure plates 401 on both sides, the valve as a whole is in a fixed state. When the pressure resistance test is performed, the lifting drive 605 can drive the chuck 603 to move up and contact the valve handle. This orientation of the valve is due to the use of the support seats 203 on both sides to transfer the valve. Due to the uneven center of gravity of the valve as a whole, the valve handle can automatically flip to a downward state, so that the handle can be controlled to rotate through the chuck 603, so that the valve can be switched between the open and closed states, so that the pressure resistance test can be performed in different states of the valve, which can not only detect the sealing of the valve core component of the valve, but also ensure the integrity of the pressure resistance test data.
