Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, specifically to a device for testing the sealing performance of ordinary valves. Background Technology

[0002] During the valve manufacturing process, the valve core inside the valve often fails to close tightly due to processing and assembly errors. When the valve core does not close tightly, fluid can pass through the valve at will, leading to valve failure. Therefore, after the valve is manufactured, its sealing performance needs to be tested. Only valves that pass the sealing test can be shipped out for use.

[0003] Currently, when testing the sealing performance of valves, most methods involve connecting one end of a flexible hose to the fluid output end of the valve and immersing the other end of the hose in water. Air is then supplied to the fluid input end of the valve. When the valve core inside the valve does not close tightly, air passes through the valve and is transported to the water through the hose, creating air bubbles. This is used to determine the valve's sealing performance. However, existing methods mostly involve manually operating each valve for testing, which is inefficient. Therefore, we propose a sealing performance testing device for ordinary valves to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sealing performance testing device for ordinary valves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing performance testing device for ordinary valves, comprising a transparent barrel, a testing platform fixedly connected to the top of the transparent barrel, one end of a cylinder fixedly connected to the center of the top of the testing platform, the other end of the cylinder coaxially fixedly connected to a top plate, a multi-way valve fixedly connected to the center of the top of the top plate, several connecting pipes fixedly connected to one end of each multi-way valve, and connecting heads fixedly connected to the other ends of each connecting pipe, the connecting heads fixedly mounted on the top plate with an upper sleeve connecting pipe fixedly connected to the end of the connecting head away from the connecting pipe, the upper sleeve connecting pipe being located at the bottom of the top plate, a lower sleeve connecting pipe fixedly connected to the testing platform at the bottom of each upper sleeve connecting pipe, a material release assembly slidably sleeved on the outside of the lower sleeve connecting pipe, the material release assembly being fixedly connected to the testing platform, and a connecting hose fixedly connected to the bottom of each lower sleeve connecting pipe, the connecting hose being located inside the transparent barrel.

[0006] Preferably, the transparent bucket is filled with water.

[0007] Preferably, the lower sleeve pipe and the upper sleeve pipe are configured in a one-to-one correspondence.

[0008] Preferably, the unloading assembly includes a ring, a groove, an operating rod, a cylindrical pin, a support frame, and an operating plate. The ring is slidably fitted with a lower sleeve pipe. The middle portions of both sides of the ring are respectively provided with grooves. Cylindrical pins are slidably engaged in the grooves. One end of the cylindrical pin opposite to the other end is hinged to one end of the operating rod. The other ends of the operating rod are respectively hinged to one end of the support frame. The other end of the support frame is fixedly connected to the top of the detection table. The end of the operating rod is fixedly connected to the operating plate.

[0009] Preferably, the operating lever has a Y-shaped structure, and the axes of the cylindrical pins are on the same straight line.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By interfering with the two ends of the valve through the lower sleeve and the upper sleeve respectively, gas is supplied to the valve to test its sealing performance. When the valve is properly sealed, no gas is supplied in the connecting hose. When the valve has a sealing problem, gas is supplied to the connecting hose, and air bubbles appear inside the transparent barrel, thus achieving rapid testing of the valve's sealing performance. This application can test multiple ordinary valves simultaneously, improving testing efficiency. Attached Figure Description

[0014] 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.

[0015] Example 1

[0016] Reference Figure 1 , 2This is the first embodiment of the present invention. This embodiment provides a sealing performance testing device for ordinary valves, including a transparent barrel 1. A testing platform 2 is fixedly connected to the top of the transparent barrel 1. One end of a cylinder 5 is fixedly connected to the center of the top of the testing platform 2. The other end of the cylinder 5 is coaxially fixedly connected to a top plate 6. A multi-way valve 10 is fixedly connected to the center of the top of the top plate 6. Several connecting pipes 9 are fixedly connected to one end of each multi-way valve 10. The other end of each connecting pipe 9 is fixedly connected to a connector 8. The connector 8 is fixedly installed on the top plate 6, and the end of the connector 8 away from the connecting pipe 9 is fixedly connected to an upper sleeve pipe 7. The upper sleeve pipe 7 is located at the bottom of the top plate 6. The bottom of each upper sleeve pipe 7 is provided with a lower sleeve pipe 3 fixedly connected to the testing platform 2. A material release assembly 4 is slidably sleeved on the outside of the lower sleeve pipe 3. The material release assembly 4 is fixedly connected to the testing platform 2. A connecting hose 11 is fixedly connected to the bottom of each lower sleeve pipe 3. The connecting hose 11 is located inside the transparent barrel 1.

[0017] Water is injected into the transparent tank 1. One end of the ordinary valve is press-fitted to the lower sleeve 3, and the other end of the ordinary valve is aligned with the upper sleeve 7. Then, the cylinder 5 retracts, causing the fixed top plate 6 to descend. The top plate 6 then causes the fixed upper sleeve 7 to descend synchronously. After descending, the upper sleeve 7 is finally press-fitted to the output of the ordinary valve. The multi-way valve 10 is connected to an air pump through a pipeline. The air pump delivers gas to the multi-way valve 10. The delivered gas is finally delivered from the connecting pipe 9 into the connector 8, and then from the connector 8 to the upper sleeve 7, and finally from the upper sleeve 7 to the ordinary valve. Inside the valve, the ordinary valve is in the closed state. When the ordinary valve has a good seal, it remains sealed, and gas cannot continue to pass through, meaning gas can enter the lower sleeve 3. When the ordinary valve has a sealing problem, gas passes through the ordinary valve and enters the lower sleeve 3, and then enters the connecting hose 11. The connecting hose 11 is immersed in the water source, which will generate bubbles, making it convenient for the testing personnel to check and judge. After the test is completed, the cylinder 5 is raised, and the cylinder 5 drives the fixed upper sleeve 7 to be raised. The upper sleeve 7 is detached from the ordinary valve, and then the unloading component 4 is operated to facilitate the removal of the ordinary valve.

[0018] Example 2

[0019] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, water is injected into the transparent barrel 1, and the end of the connecting hose 11 is immersed in the water. When gas enters the connecting hose 11, bubbles will appear, which is convenient for the testers to check and judge.

[0020] Specifically, the lower sleeve pipe 3 and the upper sleeve pipe 7 are set in a one-to-one correspondence, which makes it convenient for ordinary valves to be connected to both ends respectively.

[0021] Specifically, the unloading assembly 4 includes a ring 41, a chute 42, an operating rod 43, a cylindrical pin 44, a support frame 45, and an operating plate 46. The ring 41 is slidably sleeved with the lower sleeve pipe 3. The middle of both sides of the ring 41 are respectively provided with a chute 42, and the cylindrical pin 44 is slidably engaged in the chute 42. The opposite ends of the cylindrical pin 44 are respectively hinged to one end of the operating rod 43. The other ends of the operating rod 43 are respectively hinged to one end of the support frame 45. The other end of the support frame 45 is fixedly connected to the top of the detection table 2. The end of the operating rod 43 is fixedly connected to the operating plate 46.

[0022] Furthermore, the operating lever 43 has a Y-shaped structure, and the axes of the cylindrical pins 44 are on the same straight line.

[0023] Manually press the operating plate 46 to cause the fixed operating rod 43 to swing around the support frame 45. The operating rod 43 then causes the cylindrical pin 44 connected to the end to swing. The cylindrical pin 44 slides in the slide groove 42. At the same time, the cylindrical pin 44 causes the ring body 41 to rise. Then, through the lever principle, the ring body 41 abuts against the end of the ordinary valve, making it easy to remove the ordinary valve.

[0024] Example 3

[0025] Reference Figure 1-2 This is the third embodiment of the present invention. Based on the previous two embodiments, during testing, water is injected into the transparent barrel 1. One end of the ordinary valve's inlet is interference-fitted with the lower sleeve pipe 3, and the other end of the ordinary valve's outlet is aligned with the upper sleeve pipe 7. Then, the cylinder 5 retracts, causing the fixed top plate 6 to descend. The top plate 6 then causes the fixed upper sleeve pipe 7 to descend synchronously. After descending, the upper sleeve pipe 7 is finally interference-fitted with the outlet of the ordinary valve. The multi-way valve 10 is connected to an air pump via a pipeline. The air pump delivers gas to the multi-way valve 10. The delivered gas is ultimately delivered from the connecting pipe 9 into the connector 8, then from the connector 8 to the upper sleeve pipe 7, and finally from the upper sleeve pipe 7 to the ordinary valve. The ordinary valve is in a closed state. When the ordinary valve has good sealing performance, it maintains its sealing. Gas cannot continue to pass through, meaning gas enters the lower sleeve pipe 3. When the ordinary valve has a sealing problem, gas passes through the ordinary valve and enters the lower sleeve pipe 3, then enters the connecting hose 11. The connecting hose 11 is immersed in the water source, which will generate bubbles, making it convenient for the testing personnel to check and judge. After the test is completed, the cylinder 5 is raised, and the cylinder 5 drives the fixed upper sleeve pipe 7 to be raised. The upper sleeve pipe 7 is separated from the ordinary valve. Then, the material removal component 4 is operated, and the operating plate 46 is manually pressed, which drives the fixed operating rod 43 to swing around the support frame 45. The operating rod 43 then drives the cylindrical pin 44 connected to the end to swing. The cylindrical pin 44 slides in the slide groove 42. At the same time, the cylindrical pin 44 drives the ring body 41 to be raised. Then, through the lever principle, the ring body 41 abuts against the end of the ordinary valve, making it convenient to remove the ordinary valve.
