Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to a pressure valve testing instrument. Background Technology

[0002] In the daily operation of oil depots, shuttle-shaped pressure-reducing valves used on oil transportation pipelines play a crucial role. They effectively regulate the pressure of oil within the pipelines, ensuring the safety and stability of the oil transportation process. According to relevant oil depot management regulations, shuttle-shaped pressure-reducing valves need to undergo regular annual inspections to ensure they can properly relieve pressure under required conditions, preventing safety accidents caused by valve failure.

[0003] However, current testing of shuttle-shaped pressure reducing valves typically requires disassembling them from oil pipelines and sending them to specialized testing institutions. This method has many drawbacks. Disassembling and transporting the valves consumes a significant amount of manpower and time, especially for large oil depots with a large number of valves, resulting in a massive workload. Furthermore, the testing cycle is long, often failing to provide timely feedback on the results, posing a potential safety hazard to oil depot management. Therefore, we propose a pressure valve testing instrument to address these issues. Utility Model Content

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a pressure valve detector.

[0026] Reference Figure 1-4 A pressure valve 104 tester includes a test box 101. A water tank 103 is installed on the top of the test box 101, and the pressure valve 104 to be tested is placed in the water tank 103. A fixing plate 201 is installed on the top of the test box 101. A pressure gauge 202 and a regulating valve 203 are installed on the front side of the fixing plate 201. The regulating valve 203 is located to the left of the pressure gauge 202. A connecting pipe 204 is installed between the pressure gauge 202 and the regulating valve body. An air supply pipe 205 is installed on the regulating valve body, and one end of the air supply pipe 205 is connected to... There is a quick-connect air valve 206 connected to the pressure valve 104. The test box 101 is equipped with an air supply mechanism connected to the pressure gauge 202. Two drive plates 301 are slidably installed on the bottom inner wall of the water tank 103. A fixed seat 302 is fixedly installed on one side of the drive plate 301. An arc-shaped clamping plate 303 for fixing the pressure valve 104 is fixedly installed on one side of the fixed seat 302. A support plate 401 is fixedly installed on the top of the drive plate 301. A clamping mechanism for pressing the quick-connect air valve 206 is provided on the support plate 401.

[0027] In this embodiment, the air supply mechanism includes an air compressor that provides pressure for testing. The air compressor is equipped with a compressed air delivery pipe, and one end of the compressed air delivery pipe is connected to the pressure gauge 202. The air compressor can stably generate compressed gas, providing a continuous and stable pressure source for the pressure valve 104 to detect, ensuring the smooth progress of the detection process.

[0028] In this embodiment, the clamping mechanism includes an L-shaped plate 402, a threaded hole 403, a fixing screw 404, a clamping plate 405, and a knob 406. The L-shaped plate 402 is fixedly installed on the top of the support plate 401. The top of the L-shaped plate 402 has a threaded hole 403, and the fixing screw 404 is installed in the threaded hole 403. The bottom end of the fixing screw 404 is fixedly installed with a clamping plate 405 for fixing the quick connector 206 to the pressure valve 104. The top end of the fixing screw 404 is fixedly installed with a knob 406. By rotating the knob 406, the fixing screw 404 is rotated, which in turn pushes the clamping plate 405 to move up and down, thereby clamping and fixing the quick connector 206, effectively ensuring the sealing between the quick connector 206 and the pressure valve 104, and avoiding gas leakage from affecting the test results.

[0029] In this embodiment, two vertical plates 501 are fixedly installed on the bottom inner wall of the water tank 103, and a guide rod 502 is fixedly installed on the other side of the drive plate 301. The guide rod 502 passes through the corresponding vertical plate 501. The vertical plates 501 and the guide rod 502 provide guidance for the sliding of the drive plate 301, ensuring that the drive plate 301 remains stable during movement and avoiding deviation, thereby ensuring that the arc-shaped clamping plate 303 can accurately fix the pressure valve 104.

[0030] In this embodiment, two sliding holes are provided on the vertical plate 501, and the guide rod 502 is slidably connected to the corresponding sliding hole. The sliding hole allows the guide rod 502 to slide smoothly on the vertical plate 501, reducing the frictional resistance between the guide rod 502 and the vertical plate 501, and improving the flexibility and stability of the drive plate 301 movement.

[0031] In this embodiment, a threaded hole 601 is provided on the vertical plate 501. An adjusting screw 602 is installed in the threaded hole 601. One end of the adjusting screw 602 is rotatably mounted on the drive plate 301, and the other end of the adjusting screw 602 is fixedly mounted with a handle 603. The operator rotates the handle 603 to drive the adjusting screw 602 to rotate. Since the adjusting screw 602 is threadedly connected to the threaded hole 601 on the vertical plate 501, the adjusting screw 602 will push the drive plate 301 to slide along the guide rod 502 during rotation, thereby achieving the purpose of adjusting the distance between the two arc-shaped clamping plates 303 to stably fix the pressure valve 104.

[0032] In this embodiment, a rotating groove is provided on the other side of the drive plate 301, and an annular groove is provided on the inner wall of the rotating groove. An annular seat is fixedly installed on the adjusting screw 602, and the annular seat is rotatably connected to the corresponding annular groove. The cooperation between the annular seat and the annular groove enables the adjusting screw 602 to rotate stably on the drive plate 301, while preventing the adjusting screw 602 from separating from the drive plate 301 during rotation, thus ensuring that the pushing action of the adjusting screw 602 on the drive plate 301 is stable and reliable.

[0033] In this embodiment, the bottom of the testing box 101 is equipped with multiple casters 102, and the casters 102 are set as lockable casters. The lockable casters allow the testing instrument to move flexibly according to the testing requirements, making it convenient for staff to adjust the placement of the testing instrument. When the testing instrument is moved to the designated position, it can be fixed by locking the casters 102 to prevent the testing instrument from moving during the testing process and ensure the stable progress of the testing work.

[0034] The working principle of this utility model is as follows: First, the shuttle-shaped pressure reducing valve to be tested is placed in the water tank 103. By rotating the handle 603 on the vertical plate 501, the adjusting screw 602 is driven to rotate. The adjusting screw 602 pushes the drive plate 301 to slide along the guide rod 502, thereby adjusting the distance between the two arc-shaped clamping plates 303, so that the arc-shaped clamping plates 303 firmly fix the shuttle-shaped pressure reducing valve to be tested. Next, the quick connector 206 of the air valve is connected to the air inlet end of the shuttle-shaped pressure reducing valve. Then, the knob 406 on the top of the L-shaped plate 402 on the support plate 401 is rotated, which drives the fixing screw 404 to move downward. The fixing screw 404 pushes the pressing plate 405 to move downward, pressing the quick connector 206 tightly onto the shuttle-shaped pressure reducing valve, ensuring that there is no gas leakage in the contact gap between the quick connector 206 and the pressure reducing valve.

[0035] Next, the air compressor in the test chamber 101 is started. The air compressor generates compressed gas, which is delivered to the pressure gauge 202 through the compressed air delivery pipe. The operator adjusts the pressure value of the compressed gas to the test value desired by the customer by adjusting the regulating valve 203 on the front side of the fixed plate 201. At this time, the pressure gauge 202 can display the current pressure value in real time, which is convenient for the operator to observe and confirm. By opening the gas valve switch, the compressed gas enters the shuttle-shaped pressure reducing valve through the regulating valve 203, connecting pipe 204, gas delivery pipe 205 and gas valve quick connector 206. Then, the outlet end of the shuttle-shaped pressure reducing valve is immersed in the water tank 103 that has been prepared in advance.

[0036] Finally, observe the situation near the air outlet of the shuttle-shaped pressure reducing valve in water tank 103. If bubbles emerge, it indicates that the shuttle-shaped pressure reducing valve can open normally to release pressure under the current test pressure, which meets the customer's usage requirements. If no bubbles emerge, it indicates that the shuttle-shaped pressure reducing valve cannot release pressure normally under the current test pressure and needs to be repaired or replaced.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
