Description

Technical Field

[0001] This invention relates to the field of valve testing technology, specifically a pressure testing device for testing ship valves. Background Technology

[0002] Valves are control devices for fluid pipelines. Their basic functions are to connect or disconnect the flow of media, change the flow of media, change the flow direction of media, regulate the pressure and flow rate of media, and protect the normal operation of pipeline equipment. Before leaving the factory, valves undergo a series of tests to confirm that they are free from internal leakage, defects such as micropores and cracks in the valve body, and to verify that the valve's pressure resistance meets design requirements. However, valves may still experience leakage problems during use, so regular testing is necessary. Referring to Chinese patent publication number "CN214621706U" entitled "A Pressure Testing Device for Detecting Ship Valves," this patent points out that the current testing method has a significant discrepancy between the connection method and the actual usage method, which can lead to large errors in the test results. However, this device still suffers from problems such as a cumbersome testing method and a limited scope of application. To address these issues, we propose a pressure testing device for detecting ship valves. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0032] Example 1:

[0033] In this embodiment of the invention, a pressure testing device for detecting ship valves includes a body 1, a bearing plate 2 fixedly installed on the top surface of the body 1, the bearing plate 2 being used to support the valve to be tested, and side plates 3 and positioning plates 8 fixedly installed on both sides of the top surface of the bearing plate 2 respectively.

[0034] In this embodiment of the invention, a transmission sleeve 4 is slidably connected inside the side plate 3. A detection plate 5 is fixedly installed at one end of the transmission sleeve 4 near the positioning plate 8. The detection plate 5 is used to contact one end of the valve to be tested and slides towards the positioning plate 8 with the transmission sleeve 4 to push the valve to be tested until the positioning plate 8 completes the clamping and locking of the valve to be tested.

[0035] Specifically, when the valve to be tested is placed above the bearing plate 2, the transmission sleeve 4 moves towards the valve to be tested, which can drive the detection plate 5 to move horizontally until the detection plate 5 contacts the valve to be tested and pushes the valve to be tested to move towards the side plate 3 until the valve to be tested is clamped and locked through the cooperation of the side plate 3 and the detection plate 5.

[0036] Specifically, a connecting pipe 401 is fixedly installed inside the transmission sleeve 4, and a drain channel 501 that communicates with the connecting pipe 401 is opened inside the detection plate 5. A sealing ring 502 is fixedly installed on the side of the detection plate 5.

[0037] Specifically, after the valve under test is clamped and locked, the sealing ring 502 can be located at the liquid inlet end of the valve under test to ensure sealing. Then, the liquid is introduced into the valve under test through the connecting pipe 401 and the drain channel 501. During the introduction, the liquid can pass through the valve under test and then be discharged through the through hole opened inside the positioning plate 8. The position of the through hole is coaxial with the detection plate 5. A drain pipe 9 is provided on the outside of the through hole. The drain pipe 9 is fixedly installed on the outside of the positioning plate 8 for discharging the liquid.

[0038] Specifically, a drive cylinder 7 is fixedly installed inside the side plate 3, a transmission ring frame 6 is fixedly installed on the outside of the detection disc frame 5, the piston end of the drive cylinder 7 is fixedly connected to the transmission ring frame 6, and is used to drive the transmission ring frame 6 and the detection disc frame 5 to move. A pressure detection module 503 is fixedly installed inside the detection disc frame 5.

[0039] Specifically, during the test, when the liquid flows through the valve to be tested, the valve is closed, and the pressure value is recorded with the help of the pressure detection module 503.

[0040] Furthermore, a limiting slide rod 601 is fixedly installed on the outer side of the transmission ring frame 6. The limiting slide rod 601 passes through the side plate 3 and is slidably connected to it. When the drive cylinder 7 runs and drives the transmission ring frame 6 and the detection plate frame 5 to move, the limiting slide rod 601 can slide inside the side plate 3 to ensure the running stability of the detection plate frame 5 and improve the sealing between the detection plate frame 5 and the valve to be tested.

[0041] Furthermore, a sealing gasket 801 is fixedly installed on the side of the positioning plate 8 near the side plate 3. The sealing gasket 801 is coaxial with the detection plate frame 5 to ensure the sealing between the positioning plate 8 and the valve to be tested.

[0043] In this embodiment of the invention, a transmission sleeve 4 is slidably connected inside the side plate 3. A detection plate 5 is fixedly installed at one end of the transmission sleeve 4 near the positioning plate 8. The detection plate 5 is used to contact one end of the valve to be tested and slides towards the positioning plate 8 with the transmission sleeve 4 to push the valve to be tested until the positioning plate 8 completes the clamping and locking of the valve to be tested.

[0044] Specifically, when the valve to be tested is placed above the bearing plate 2, the transmission sleeve 4 moves towards the valve to be tested, which can drive the detection plate 5 to move horizontally until the detection plate 5 contacts the valve to be tested and pushes the valve to be tested to move towards the side plate 3 until the valve to be tested is clamped and locked through the cooperation of the side plate 3 and the detection plate 5.

[0045] Specifically, a connecting pipe 401 is fixedly installed inside the transmission sleeve 4, and a drain channel 501 that communicates with the connecting pipe 401 is opened inside the detection plate 5. A sealing ring 502 is fixedly installed on the side of the detection plate 5.

[0046] Specifically, after the valve under test is clamped and locked, the sealing ring 502 can be located at the liquid inlet end of the valve under test to ensure sealing. Then, the liquid is introduced into the valve under test through the connecting pipe 401 and the drain channel 501. During the introduction, the liquid can pass through the valve under test and then be discharged through the through hole opened inside the positioning plate 8. The position of the through hole is coaxial with the detection plate 5. A drain pipe 9 is provided on the outside of the through hole. The drain pipe 9 is fixedly installed on the outside of the positioning plate 8 for discharging the liquid.

[0047] Specifically, a drive cylinder 7 is fixedly installed inside the side plate 3, a transmission ring frame 6 is fixedly installed on the outside of the detection disc frame 5, the piston end of the drive cylinder 7 is fixedly connected to the transmission ring frame 6, and is used to drive the transmission ring frame 6 and the detection disc frame 5 to move. A pressure detection module 503 is fixedly installed inside the detection disc frame 5.

[0048] Specifically, during the test, when the liquid flows through the valve to be tested, the valve is closed, and the pressure value is recorded with the help of the pressure detection module 503.

[0049] Furthermore, a limiting slide rod 601 is fixedly installed on the outer side of the transmission ring frame 6. The limiting slide rod 601 passes through the side plate 3 and is slidably connected to it. When the drive cylinder 7 runs and drives the transmission ring frame 6 and the detection plate frame 5 to move, the limiting slide rod 601 can slide inside the side plate 3 to ensure the running stability of the detection plate frame 5 and improve the sealing between the detection plate frame 5 and the valve to be tested.

[0050] Furthermore, a sealing gasket 801 is fixedly installed on the side of the positioning plate 8 near the side plate 3. The sealing gasket 801 is coaxial with the detection plate frame 5 to ensure the sealing between the positioning plate 8 and the valve to be tested.

[0051] Furthermore, a bearing plate 11 is slidably connected to the top surface of the bearing plate 2. The bearing plate 11 is used to support the valve to be tested. Multiple annular holes are opened inside the bearing plate 11, and a support slide rod 12 is slidably connected inside each annular hole. A spring body 1202 is sleeved on the outside of each of the multiple support slide rods 12.

[0052] By setting up the support plate 11, when the valve to be tested is placed on the support plate 11, the corresponding support slide rod 12 can be pressed down. At this time, the corresponding spring body 1202 is compressed and retracted. At the same time, the anti-slip pad 1201 at the end of the support slide rod 12 located below the valve to be tested can fit against the outside of the valve to be tested. When the detection plate 5 moves to push the valve to be tested, the support plate 11 can slide on the support plate 2 with the valve to be tested, thereby ensuring the placement stability of the valve to be tested during the detection process and improving the ease of operation and detection efficiency of the equipment.

[0053] Furthermore, the installation height of the multiple support slide rods 12 is kept at the same level, and the ends of the support slide rods 12 are all fixedly installed with anti-slip pads 1201;

[0054] Furthermore, a rectangular slot 10 is provided inside the bearing plate 2, and a rectangular slide plate 14 is slidably installed inside the rectangular slot 10. A support spring 1001 is fixedly installed between the rectangular slide plate 14 and the inner wall of the rectangular slot 10. A bottom slide rod 1101 is fixedly installed at the bottom center of the bearing plate frame 11. The bottom slide rod 1101 passes through the rectangular slide plate 14. With the cooperation of the rectangular slide plate 14, when the valve to be tested is subjected to force and moves, the bottom slide rod 1101 can simultaneously drive the rectangular slide plate 14 to slide inside the rectangular slot 10.

[0055] Specifically, a drive assembly is provided on the outside of the bottom slide rod 1101 to drive the bottom slide rod 1101 and the bearing plate frame 11 to rotate, thereby adjusting the direction of the valve to be tested. The drive assembly includes a drive motor 1501. A limit slide 13 is slidably installed inside the body 1. The limit slide 13 is fixedly connected to the bottom of the rectangular slide plate 14.

[0056] Specifically, the transmission gear 16 sleeved on the output end of the drive motor 1501 is fixedly connected to it, and the transmission gear 16 sleeved on the outside of the bottom slide rod 1101 is slidably connected to it. The transmission gear 16 on the outside of the bottom slide rod 1101 is rotatably connected to the bottom of the rectangular slide plate 14 to avoid affecting the bottom slide rod 1101 sliding up and down inside the rectangular slide plate 14. The bottom slide rod 1101 can maintain rotation while sliding up and down inside the rectangular slide plate 14.

[0057] A lifting cylinder 17 is fixedly installed inside the limiting slide 13. The piston end of the lifting cylinder 17 is rotatably connected to the bottom slide rod 1101, which is used to drive the bottom slide rod 1101 to slide upward.

Then, the drive motor 1501 can be used to drive the bottom slide rod 1101 and the support plate 11 to rotate through the transmission gear 16, thereby adjusting the angle of the valve to be tested until the end of the valve to be tested is coaxial with the detection plate 5. Then, the detection plate 5 can be used to clamp and test the valve to be tested.

[0060] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
