[0002] A gate valve sealing performance testing device is mainly used to test the sealing performance of the gate valve in the closed state, ensuring that it can effectively isolate the fluid in the pipeline and prevent leakage. The sealing performance of the gate valve directly affects the safety and reliability of the fluid system, therefore, testing its sealing performance is very important.

[0003] The shortcomings of existing technology:

[0004] Most current gate valve sealing testing devices install the gate valve in a closed pipeline system with the valve in the closed state. Gas is injected through one end of the pipeline and the other end is sealed. A digital vacuum gauge is used to detect whether there is gas leakage at the valve's closed position. However, when using the device, due to the excessive length of the pipeline, in some cases, there is no reasonable storage and fixing mechanism, which can easily cause problems such as tripping over workers, gas leakage, and damage.

[0018] A pressure sensor is fixedly connected to one side of the top surface of the detection fixture.

[0019] Preferably, a limiting groove is formed on the inner surface of the detection fixture, and a silicone ring is bonded inside the limiting groove to facilitate sealing of the detection end of the shut-off valve and prevent air from penetrating inside, which would affect the normal detection of the device.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This is a gate valve sealing performance testing device. The cable management mechanism includes a connecting block, a slide rail, a ball block A, a telescopic rod, a rotating shaft block, and an arc-shaped clamping plate. By adjusting the length of the telescopic rod, the connecting block and ball block A are moved to one side under the action of the slide rail, so that ball block A is engaged in one of the slots to fix the telescopic rod. Excess delivery pipe is wound around the surface of the telescopic rod. Under the action of the rotating shaft block, the arc-shaped clamping plate is engaged with the top of the wound delivery pipe to fix it.

This shut-off valve sealing performance testing device includes a fixing mechanism comprising two telescopic plates, two hydraulic rods, a connecting plate, a silicone pad, and a pressure sensor. When using the device, one end of the shut-off valve is inserted into the silicone ring. Depending on the size of the shut-off valve, the distance between the two hydraulic rods is adjusted using the two telescopic plates to apply pressure to the surface of the pressure sensor. The pressure sensor transmits a signal to the control panel, which then drives the two sets of telescopic plates to move the connecting plate and silicone pad downwards until the silicone pad adheres to the top surface of the shut-off valve and is fixed in place. This ensures that the valve remains stable during the test, preventing valve shaking or position changes from affecting the sealing performance test results. Attached Figure Description

[0036] Example 1

[0037] Please see Figure 1-4As shown, the present invention provides a technical solution for a shut-off valve sealing performance testing device: It includes a vacuum pump 1, with multiple slots on one side of its outer surface. A wire harness mechanism 2 is fixedly connected to the outer surface of the vacuum pump 1, and a delivery pipe 3 is connected to the other side of the outer surface of the vacuum pump 1. A detection fixing component 4 is connected to the end of the delivery pipe 3, and fixing mechanisms 5 are fixedly connected to both sides of the detection fixing component 4. The wire harness mechanism 2 includes a connecting block 201, which is fixedly connected to the outer surface of the vacuum pump 1; a slide rail 202, which is fixedly connected to one side of the connecting block 201; a ball block A203, which is fixedly connected to one end of the connecting block 201, with its outer surface engaging with one set of slots; a telescopic rod 204, which is slidably connected to one side of the slide rail 202; and a rotating shaft block 2. 05. The rotating shaft block 205 is fixedly connected to one side of the telescopic rod 204. One end of the rotating shaft block 205 is fixedly connected to the outer surface of the vacuum pump 1. The arc-shaped clamping plate 206 is rotatably connected to one side of the rotating shaft block 205. The length of the telescopic rod 204 is adjusted, and then the connecting block 201 and the ball block A203 are moved to one side under the action of the sliding rail 202, so that the ball block A203 is engaged in one of the slots to fix the telescopic rod 204. The excess conveying pipe 3 is wound around the surface of the telescopic rod 204. Under the action of the rotating shaft block 205, the arc-shaped clamping plate 206 is engaged with the top of the wound conveying pipe 3 to fix it. This makes it convenient to store the conveying pipe 3 to a suitable length according to the site conditions, and avoids problems such as tripping over workers, air leakage, and damage caused by the lack of a reasonable storage and fixing mechanism in some cases.

[0038] The fixing mechanism 5 includes two telescopic plates 501, which are fixedly connected to both sides of the detection fixing member 4; two hydraulic rods 502, which are respectively welded to the top surfaces of the two telescopic plates 501; a connecting plate 503, which is fixedly connected to the output ends of the two hydraulic rods 502; a silicone pad 504, which is adhered to the bottom surface of the arc-shaped clamping plate 206; and a pressure sensor 505, which is fixedly connected to one side of the top surface of the detection fixing member 4. When using the device, the shut-off valve is... The end is inserted into the silicone ring 7. According to the size of the shut-off valve, the distance between the two hydraulic rods 502 is adjusted by the two telescopic plates 501 respectively, and pressure is applied to the surface of the pressure sensor 505. The pressure sensor 505 transmits the signal to the control panel. The control panel drives the two sets of telescopic plates 501 to move the connecting plate 503 and the silicone pad 504 downward until the silicone pad 504 is attached to the top surface of the shut-off valve to fix it. This can ensure that the valve remains stable during the test and avoid the valve shaking or position change affecting the sealing test results.

[0039] A limiting groove 6 is formed on the inner surface of the detection fixture 4. A silicone ring 7 is bonded inside the limiting groove 6 to facilitate sealing of the detection end of the shut-off valve and prevent air from penetrating inside, which would affect the normal detection of the device.

[0040] Both ends of the bottom of the vacuum pump 1 are welded with a support frame 8, and the bottom of the two support frames 8 are welded with long plates 9 to prevent the bottom of the vacuum pump 1 from touching the ground and causing wear.

[0041] Multiple casters 10 are fixedly connected to the bottom of the two long plates 9. Each caster 10 has a brake pad installed inside, which makes it easy to move the device to a designated position for use.

[0042] A digital vacuum gauge, model MKS 901P, is connected to one end of the top surface of the detection fixture 4. This allows for convenient testing of whether the shut-off valve of the vacuum pump 1 is properly sealed.

[0043] The vacuum pump model 1 is IRocker410.

[0044] In this device, adjusting the length of the telescopic rod 204 causes the connecting block 201 and ball block A203 to move to one side under the action of the sliding rail 202. This allows ball block A203 to engage in one of the slots, securing the telescopic rod 204. Excess conveying pipe 3 is then wound around the surface of the telescopic rod 204. Under the action of the rotating shaft block 205, the arc-shaped clamping plate 206 engages with the top of the wound conveying pipe 3, securing it. This allows the conveying pipe 3 to be stored to a suitable length according to site conditions, avoiding problems such as tripping, air leakage, and damage caused by the lack of a proper storage and fixing mechanism in certain situations. Furthermore, when using the device, one end of the shut-off valve is inserted into the silicone ring 7. Depending on the size of the shut-off valve, the two telescopic rods are used to... Plate 501 adjusts the distance between the two hydraulic rods 502 to apply pressure to the surface of pressure sensor 505. Pressure sensor 505 transmits the signal to control panel. Control panel drives two sets of telescopic plates 501 to move connecting plate 503 and silicone pad 504 downwards until silicone pad 504 is attached to the top surface of the shut-off valve to fix it. This ensures that the valve remains stable during the test and avoids affecting the sealing test results due to valve shaking or position changes. Vacuum pump 1 is driven to start working, creating a negative pressure environment in the cavity. The vacuum degree in the cavity can be detected by a digital vacuum gauge connected to one end of the top surface of the detection fixture 4. The sealing performance of the shut-off valve can be judged by the vacuum degree on the digital vacuum gauge.
