Description

Technical Field

[0001] This utility model relates to the field of testing technology, and more specifically, to a water testing machine for temperature control valves. Background Technology

[0002] Air tightness testing is an important part of parts manufacturing. The most common method for testing air tightness is to have workers place the parts in a water tank and observe whether air bubbles are generated to determine if there is a leak. Finally, the tested parts need to be manually removed from the water tank.

[0003] The existing water testing machine requires manual placement of the test parts inside a transparent limiting frame before testing, and removal of the test parts after testing. Since the transparent limiting frame is located inside the limiting frame, the placement and removal of the test parts is extremely inconvenient.

[0004] A search revealed a water testing machine disclosed in Chinese Patent No. CN221376964U. This utility model uses a second drive mechanism connected to a placement platform. This allows the second drive mechanism to move the placement platform, moving the workpiece to be tested from inside or outside the frame. After the placement platform moves out of the frame, workers can then pick up or put down the workpiece without having to reach into the frame, making it more convenient for workers.

[0005] However, in actual use, when the above-mentioned water testing machine is used to test the airtightness of the valve body, due to the different valve body models and the fact that the valve body has multiple connection ports, it is not convenient to position the valve body, which will reduce the connection seal of the valve body and affect the testing efficiency and accuracy of the valve body. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a water testing machine for temperature control valve testing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water testing machine includes a frame, a top plate fixedly connected to the top of the frame, an inner frame fixedly connected to the bottom of the top plate, and a positioning mechanism disposed on the inner side of the inner frame. The positioning mechanism includes a first cylinder, one side of which is fixedly connected to the upper surface of the inner frame, and a second cylinder fixedly connected to one side of the inner frame. A pusher is fixedly connected to the output ends of the first and second cylinders, the outer side of which is slidably connected to the inner side of the inner frame, and a silicone gasket is fixedly connected to one side of the pusher. A guide rail is fixedly connected to the inner side of the inner frame, and a base plate is slidably connected to the top of the guide rail. The output ends of the first and second cylinders both penetrate the inner side of the inner frame and extend into the inner frame. A replacement fixture is fixedly connected to one side of the base plate, and a valve body is disposed on the top of the base plate. Two dryers are installed on one side of the inner frame, and the dryers are symmetrically arranged on one side of the inner frame. A water testing mechanism is disposed on the inner side of the frame.

[0009] By adopting the above technical solution: the valve body is moved horizontally using the base plate and replacement tooling, and the pusher and silicone gasket are pushed by cylinder one and cylinder two, so that the top opening and side interface of the valve body can be squeezed and sealed with the pusher and silicone gasket, and the valve body is pressurized and depressurized by external air supply through one of the pushers and silicone gaskets.

[0010] As a further description of the above technical solution: the water testing mechanism includes multiple guide rods, one side of which is fixedly connected to the inner side of the frame, and a water tank is slidably connected to the outer side of the guide rods. A bottom cylinder is fixedly connected to the bottom of the frame, and the output end of the bottom cylinder is fixedly connected to the bottom of the water tank. Multiple mounting wheels are fixedly connected to the lower surface of the frame, and a display screen is fixedly connected to one side of the frame. An indicator light is fixedly connected to one side of the display screen.

[0011] By adopting the above technical solution: by raising and lowering the water tank inside the frame, the water inside the water tank can immerse the valve body located inside the inner frame, so that the water can detect the sealing performance of the valve body, and the inflation time, water test time and air release time of the valve body can be adjusted through the display screen and indicator lights.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a positioning mechanism, compared with the existing technology, the top and side interfaces of the valve body are positioned by opposing compression using two pushers and silicone gaskets, and the valve body is kept sealed. This facilitates pressurization inside the valve body, and the valve body surface can be cleaned by blowing air using a dryer. This allows the water testing machine to easily clamp different models of valve bodies, optimizes the operation steps, and improves the testing efficiency of the valve body.

[0014] 2. By setting up a water inspection mechanism, compared with the existing technology, the water tank is used to raise and lower the water, so that different models of valve bodies can be fully immersed in the water after positioning. This controls the water inspection time of the valve body. The sealing performance of the valve body is observed and tested by whether bubbles are generated on the water surface, combined with the display screen and indicator lights, thus improving the accuracy of valve body sealing test.

[0022] 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.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6The water testing machine for temperature control valves shown includes a frame 1, a top plate 2 fixedly connected to the top of the frame 1, and an inner frame 3 fixedly connected to the bottom of the top plate 2. A positioning mechanism is provided on the inner side of the inner frame 3. The positioning mechanism includes a first cylinder 4, one side of which is fixedly connected to the upper surface of the inner frame 3, and a second cylinder 5 fixedly connected to one side of the inner frame 3. A pusher 6 is fixedly connected to the output ends of the first cylinder 4 and the second cylinder 5. The outer side of the pusher 6 is slidably connected to the inner side of the inner frame 3. A silicone pad 7 is fixedly connected to one side of the pusher 6. A guide rail 8 is fixedly connected to the inner side of the inner frame 3, and a base plate 9 is slidably connected to the top of the guide rail 8. The output ends all penetrate through the inner side of the inner frame 3 and extend into the interior of the inner frame 3. A replacement fixture 10 is fixedly connected to one side of the base plate 9. A valve body 11 is set on the top of the base plate 9. Two dryers 12 are installed on one side of the inner frame 3. The dryers 12 are symmetrically arranged on one side of the inner frame 3. A water detection mechanism is set inside the frame 1. The valve body 11 is placed and pushed by the base plate 9 and the replacement fixture 10. The top interface and side interface of the valve body 11 are squeezed and positioned by the cylinder 4 and the silicone gasket 7 and kept sealed by the cylinder 4 and the cylinder 5. At the same time, the two dryers 12 can blow off the water on the surface of the valve body 11 after water detection.

[0024] Reference Figure 1 , Figure 2 and Figure 3 As shown, the water inspection mechanism includes multiple guide rods 15. One side of the guide rod 15 is fixedly connected to the inner side of the frame 1, and a water tank 16 is slidably connected to the outer side of the guide rod 15. A bottom cylinder 17 is fixedly connected to the bottom of the frame 1, and the output end of the bottom cylinder 17 is fixedly connected to the bottom of the water tank 16. Multiple mounting wheels 18 are fixedly connected to the lower surface of the frame 1. A display screen 13 is fixedly connected to one side of the frame 1, and an indicator light 14 is fixedly connected to one side of the display screen 13. By utilizing the cooperation between the display screen 13, the bottom cylinder 17, the water tank 16, and the guide rods 15, the water tank 16 drives the water to rise and fall, controlling the immersion time of the water and the valve body 11, and the indicator light 14 provides a prompt for the detection of the valve body 11.

[0025] The working principle of this utility model is as follows: Multiple mounting wheels 18 push the water testing machine to a suitable position. When testing the valve body 11, the base plate 9 is first pulled out from the top of the guide rail frame 8. Then, one end of the valve body 11 is placed on the upper surface of the base plate 9, aligning one side of the valve body 11 with the replacement fixture 10. The base plate 9 is then pushed to move the valve body 11 inside the inner frame 3, aligning the top and side interfaces of the valve body 11 with the two pushers 6 at one end of cylinder 4 and cylinder 5, respectively. Cylinder 4 and cylinder 5 are then activated to drive the pushers 6 and silicone gaskets 7 to press and seal the top and side interfaces of the valve body 11, thus forming a seal inside the valve body 11. Water is then injected into the water tank 16. Finally, the bottom cylinder 17 is activated to push the water tank 16 under the guidance of multiple guide rods 15, causing the water inside the water tank 16 to... As the valve rises, it is gradually submerged in water. Once fully submerged, external air is supplied through one of the pushers 6 and the silicone gasket 7 to pressurize the inside of the valve body 11. The air pressure intensity inside the valve body 11 is observed on the display screen 13. At this time, the operator observes whether bubbles emerge from the valve body 11 in the water and combines this with the stability of the air pressure intensity inside the valve body 11 displayed on the display screen 13 to judge the sealing performance of the valve body 11. Finally, after the sealing performance test of the valve body 11 is completed, the pressure inside the valve body 11 is released through one of the pushers 6 and the silicone gasket 7. Then, the indicator light 14 illuminates to remind the operator to remove the valve body 11 from the inside of the inner frame 3. Two dryers 12 are used to blow air onto the surface of the valve body 11 to remove the water, thus completing the sealing performance test of the valve body 11.
