Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, and in particular to a top-opening valve testing device. Background Technology

[0002] Valves are mechanical devices that control the flow rate, direction, pressure, temperature, etc. of flowing fluid media. Valves are basic components of pipeline systems. Top-opening valves play an important role in many fields due to their unique structure and working principle. During the processing and production of top-opening valves, it is necessary to conduct airtightness testing.

[0003] However, traditional valve sealing tests typically involve filling the valve with gas at a certain pressure and using a pressure testing device to detect changes in the pressure inside the valve to determine if there is a leak. While this method can identify whether there is a sealing problem, it cannot pinpoint the specific location of the sealing issue.

[0004] Therefore, in order to facilitate the testing of valve sealing performance and to easily locate the specific location where sealing problems exist, a top-opening valve testing device is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Reference Figures 1-5 The present invention provides an embodiment of a top-opening valve detection device, characterized in that it includes a detection base 1, a pressure detection component 2, and a fixing structure 3;

[0034] The testing base 1 includes a fixing groove 11 and a worktable 12. The worktable 12 is fixedly installed inside the fixing groove 11. When testing the valve, the valve to be tested is placed on the worktable 12.

[0035] The pressure testing component 2 is installed on the testing base 1 and is used to pressurize the valve with water. It includes a water tank 21, a water pump 22 and a pressure gauge 23. The output end of the water pump 22 is fixedly connected to a pressure pipe 24, which is used to connect to the valve to be tested. A pressure measuring pipe 26 is connected between the pressure gauge 23 and the pressure pipe 24 for detecting water pressure.

[0036] A flange 25 is fixedly connected to the pressure pipe 24. The flange 25 is used to fix the pressure pipe 24 and the valve to be tested. The flange 25 is connected to one end of the valve, so that the pressure pipe 24 is connected to the inside of the valve.

[0037] The bottom of the fixed tank 11 is provided with a drain outlet 14. Water flowing out during the test enters the fixed tank 11. When it is necessary to drain, the staff opens the drain outlet 14 to drain the stored water.

[0038] Working principle: When testing the sealing performance of a valve, the tester connects the valve's inlet end to the pressure pipe 24 via flange 25. Then, the tester starts the water pump 22, which draws water from the water tank 21 into the pressure pipe 24, and then into the valve to be tested. The tester then closes the valve, allowing the water pump 22 to continuously pressurize the valve. The tester observes whether there is any leakage or seepage on the workbench 12 to determine the valve's sealing performance. If the valve has a sealing problem, the tester can observe the location of the leak to find the part of the valve with the sealing problem.

[0039] During the testing process, staff members observed the values ​​on pressure gauge 23 to determine the sealing performance of the valve under different pressures.

[0040] Example 2:

[0041] Considering the above embodiment one, in order to further ensure the airtightness of the valve during installation, improvements to the device are necessary, such as... Figure 1 , 3 And 4, the specific structure is as follows:

[0042] The fixed structure 3 includes a threaded rod 31, a clamping plate 32, and a moving block 33. The threaded rod 31 is threadedly connected to the moving block 33, and a connecting rod 34 is fixedly connected between the clamping plate 32 and the moving block 33.

[0043] A pressure head 35 is fixedly connected to the clamp plate 32 for pressing against the end face of the valve. A through hole is opened in the middle of the pressure head 35.

[0044] A fixing block 36 is fixedly connected to the fixing groove 11, and a threaded rod 31 is rotatably connected to the fixing block 36. A throttle 38 is fixedly connected to one end of the threaded rod 31.

[0045] A slider 37 is fixedly connected to the bottom of the clamping plate 32. A slide groove 13 is provided on the worktable 12. The slider 37 is slidably connected in the slide groove 13. When the clamping plate 32 moves, the slider 37 slides in the slide groove 13 to guide the movement of the clamping plate 32.

[0046] Working principle: When installing the valve to be tested, one end of the valve is connected to the pressure pipe 24 through the flange 25. The pressure pipe 24 is a fixed rigid pipe and is fixedly installed on the fixed groove 11. The other end of the valve is pressed against the pressure head 35. The operator rotates the handle 38, which drives the threaded rod 31 to rotate. The threaded rod 31 drives the moving block 33 to move through the threaded engagement with the moving block 33, which in turn drives the clamping plate 32 to move, so that the pressure head 35 can press against one end of the valve, thereby pressing the valve between the flange 25 and the pressure head 35 to ensure the sealing during installation.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
