Description

Technical Field

[0001] This utility model relates to the field of valve processing and testing technology, specifically a valve testing device for valve processing. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. They are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of medium flow. The main function of valves is to control the fluid in the pipeline. In the case of large transport pipelines, it is necessary to ensure the quality of valves to avoid property damage. Therefore, in order to ensure the quality of valves, a sealing test is required after the valve is manufactured.

[0003] The current method for testing the sealing performance of valves involves drawing water through the valve, closing the valve, and then checking for leaks. If no water is discharged from the outlet pipe at one end of the valve, the valve is considered to have a good seal; otherwise, if water is discharged, the valve is considered to have a poor seal. During testing, it is necessary to manually monitor the outlet pipe in real time to see if water is being discharged. Since hundreds or thousands of valves are tested, this method is time-consuming, labor-intensive, and reduces the efficiency of valve testing. Utility Model Content

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figures 1-5As shown, a valve testing device for valve processing includes: a testing workbench 1, a fixed frame 101 installed on one side of the top of the testing workbench 1, a bracket 102 installed at the bottom of the testing workbench 1, and a testing assembly set on the top of the testing workbench 1. The testing assembly includes: a right connecting block 2, a water supply pipe 201, a water pump 202, a water storage tank 203, a water pumping pipe 204, a left connecting block 205, a testing box 206, a drain hose 207, a pressure sensor 208, a control panel 209, and a warning light 210. An adjustment assembly set on the top of the testing workbench 1 includes: a slide bar 3, a slide groove 301, a fixed plate 302, and an electric push rod 303.

[0026] The testing workbench 1 is equipped with a shelf 6 at its outer end. A baffle 601 is installed on the outer side of the top of the shelf 6. After the valve is produced, it is transported to the testing workbench 1 and placed on the shelf 6 for temporary placement for testing. This makes it convenient for staff to pick up and use the valve for testing. When the valve is placed, the baffle 601 protects the valve and prevents it from falling off the testing workbench 1.

[0027] The fixed frame 101 has a right connecting block 2 installed at its outer end, a water supply pipe 201 installed at one end of the right connecting block 2, a water pump 202 connected to the water supply pipe 201 installed on the fixed frame 101, a water storage tank 203 installed on the support 102, a water pumping pipe 204 installed between the water storage tank 203 and the water pump 202, a left connecting block 205 on one side of the right connecting block 2, a test box 206 installed on one side of the bottom of the test workbench 1, a drain hose 207 installed between the left connecting block 205 and the test box 206, a pressure sensor 208 installed inside the test box 206 at the position opposite to the drain hose 207, a control panel 209 installed at the outer end of the test workbench 1, and a warning light 210 installed on the top of the control panel 209.

[0028] During valve testing, place the valve on the support plate 401, align one end of the valve with the right connecting block 2, and then activate the electric push rod 303 to push the slide rod 3, moving the left connecting block 205 towards the other end of the valve until the left connecting block 205 is aligned with the other end of the valve. The valve is then clamped and fixed on the support plate 401 by the cooperation of the right connecting block 2 and the left connecting block 205, ensuring a tight fit. The valve is then closed. At this point, the water pump 202 is activated, and the water pipe 204 draws water from the storage tank 203, which is then pumped into the water supply pipe 201. Water is then drawn into the valve from the water supply pipe 201. When no water flows into the drain hose 207 and into the test box 206, and the pressure sensor 208 does not detect the gravity of the falling water, the warning light 210 will not be triggered, indicating that the valve has good sealing performance and is a qualified product.

[0029] Conversely, when water flows into the drain hose 207 from inside the valve and into the test box 206, the drain hose 207 is aligned with the pressure sensor 208. The weight of the water falls on the pressure sensor 208 and is detected by it. The pressure sensor 208 is electrically connected to the control panel 209, which is in turn electrically connected to the warning light 210. The pressure sensor 208 sends the detected information to the control panel 209 via an electrical signal. Upon receiving the information, the control panel 209 activates the warning light 210, indicating that the valve has failed the test and is a defective product due to poor sealing. During the valve testing process, there is no need for manual observation of whether water is flowing out of the drain hose 207, solving the problem of time-consuming and labor-intensive manual observation and improving the efficiency of valve testing.

[0030] The testing workbench 1 has a collection box 5 at its outer end. A partition 501 is installed in the middle of the collection box 5, which divides the inside of the collection box 5 into a qualified collection chamber and an unqualified collection chamber. After the valves are tested, the qualified finished valves are placed in the qualified collection chamber and the unqualified valves are placed in the unqualified collection chamber. The outer side of the collection box 5 is labeled with the words "qualified" and "unqualified" at the corresponding positions of the qualified and unqualified collection chambers, so that the staff can identify them. Then, the qualified valves are packaged and the unqualified valves are sent back to the production workshop.

[0031] The left connecting block 205 has a sliding rod 3 installed at its bottom. The top of the testing workbench 1 has a sliding groove 301 that is slidably connected to the sliding rod 3. A fixing plate 302 is installed on one side of the top of the testing workbench 1. An electric push rod 303 is installed on the outer end of the fixing plate 302. One end of the electric push rod 303 is connected to the sliding rod 3. When the left connecting block 205 and the right connecting block 2 are used, the right connecting block 2 is the fixed end and the left connecting block 205 is the movable end. When clamping and fixing the valve, the electric push rod 303 can push the left connecting block 205 to move towards the right connecting block 2, that is, push the sliding rod 3 to slide in the sliding groove 301, adjust the distance between it and the right connecting block 2, and then clamp and fix the valve. The left connecting block 205 can be flexibly adjusted and used to clamp and install valves of different lengths for testing.

[0032] A support block 4 is installed between the right connecting block 2 and the left connecting block 205. A support plate 401 is installed on the top of the support block 4. A groove 402 is provided on the outer end of the support plate 401. When the valve is clamped and installed, the support block 4 and the support plate 401 can support the bottom of the valve and ensure that both ends of the valve are aligned with the right connecting block 2 and the left connecting block 205 respectively. This avoids gaps between the valve and the right connecting block 2 and the left connecting block 205, which would affect the valve's sealing performance.

[0033] The groove 402 at the outer end of the support plate 401 is set towards the slide rod 3, and the length, width and diameter of the groove 402 are larger than those of the slide rod 3. When the slide rod 3 moves towards the support plate 401, the slide rod 3 enters the groove 402 and will not collide with or damage the support plate 401, ensuring that the left connecting block 205 is pushed back and forth to adjust the position and clamp the valve.

[0034] The test chamber 206 is connected to the water storage tank 203 by a return pipe 7. The water storage tank 203 has an outlet pipe 701 installed on one side of its bottom. A switch valve 702 is installed on the outlet pipe 701. After the water source is drained into the test chamber 206 by the drain hose 207, the water source inside the test chamber 206 can flow back to the water storage tank 203 for reuse due to the return pipe 7. This achieves water conservation during valve testing. However, the water source may become dirty after prolonged use. The switch valve 702 can be opened, and the outlet pipe 701 can drain the dirty water from the water storage tank 203. The top of the water storage tank 203 is equipped with an inlet pipe and a sealing cap. The sealing cap on the top of the inlet pipe can be loosened and removed, and clean water can be drained into the water storage tank 203 for storage and continued testing.

[0035] The water pump 202, pressure sensor 208, warning light 210, and electric push rod 303 of this application are electrically connected to the control panel. The control panel is provided with start and stop buttons for controlling the water pump 202, pressure sensor 208, warning light 210, and electric push rod 303. The power of the detection device in this application is provided by an external power source. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0036] Working principle:

[0037] During valve testing, place the valve on the support plate 401, align one end of the valve with the right connecting block 2, and then activate the electric push rod 303 to push the slide rod 3, moving the left connecting block 205 towards the other end of the valve until the left connecting block 205 is aligned with the other end of the valve. The valve is then clamped and fixed on the support plate 401 by the cooperation of the right connecting block 2 and the left connecting block 205, ensuring a tight fit. The valve is then closed. At this point, the water pump 202 is activated, and the water pipe 204 draws water from the storage tank 203, which is then pumped into the water supply pipe 201. Water is then drawn into the valve from the water supply pipe 201. When no water flows into the drain hose 207 and into the test box 206, and the pressure sensor 208 does not detect the gravity of the falling water, the warning light 210 will not be triggered, indicating that the valve has good sealing performance and is a qualified product.

[0038] Conversely, when water flows into the drain hose 207 from inside the valve and into the test box 206, the drain hose 207 is aligned with the pressure sensor 208. The weight of the water falls on the pressure sensor 208, which is electrically connected to the control panel 209. The control panel 209 is also electrically connected to the warning light 210. The pressure sensor 208 sends the detected information to the control panel 209 via an electrical signal. Upon receiving the information, the control panel 209 activates the warning light 210, alerting the staff that the valve has failed the test. This indicates that the valve's sealing is poor and it is a defective product. During the valve testing process, there is no need for manual observation of whether water is flowing out of the drain hose 207, solving the problem of time-consuming and labor-intensive manual observation and improving the efficiency of valve testing.

[0039] When the left connecting block 205 and the right connecting block 2 are used, the right connecting block 2 is the fixed end and the left connecting block 205 is the movable end. When clamping and fixing the valve, the electric push rod 303 can push the left connecting block 205 to move to the right connecting block 2, that is, push the slide rod 3 to slide in the slide groove 301, adjust the distance between it and the right connecting block 2, and then clamp and fix the valve. The left connecting block 205 can be flexibly adjusted and used to clamp, install and test valves of different lengths.
