Description

Technical Field

[0001] This utility model relates to the field of flange ball valve testing technology, specifically to a flange ball valve airtightness testing device. Background Technology

[0002] The airtightness test device for flange ball valves mainly involves installing and fixing the flange ball valve at both ends of the sealing cavity, filling the valve body with gas at a specified pressure through a pressure source, using pressure control to maintain a stable pressure, and simultaneously monitoring pressure changes in real time with a pressure gauge to observe whether there is gas leakage at each sealing part of the valve, thereby verifying whether the airtightness of the flange ball valve meets the standard requirements.

[0003] The prior art discloses an airtightness testing device for a flanged ball valve, with publication number CN204439311U. The device includes a base with a guide rail and at least one workstation located on one side of the guide rail. An air guide pipe is installed inside the base, connecting to the workstation, with one end extending outside the base. The end of the air guide pipe extending beyond the base is connected to compressed air. A motor is mounted on the guide rail, with its shaft facing the workstation. The motor output shaft is connected to one end of a coupling and a connecting piece, the other end of which is connected to a ball valve knob. A tee connector is located at the end of the air guide pipe outside the base. One end of the tee connector is connected to the air guide pipe via a direct connector, and the other two ends are connected to compressed air and a pressure gauge, respectively. This structure reduces the workload of testing personnel and allows for simultaneous testing of two different types of ball valves, improving testing efficiency.

[0004] The aforementioned device uses multiple stations to test different models of ball valves, improving testing efficiency. However, when using the device, it uses a single compressed air method for testing, which cannot quickly determine the location of leaks, resulting in poor performance. This needs to be improved.

[0025] The supporting mechanism 1 consists of a base plate 101, a support leg 102, a soaking tank 103, a water inlet pipe 104, and a drain pipe 105. The support leg 102 is fixedly connected to the top of the base plate 101, the soaking tank 103 is fixedly connected to the top of the soaking tank 103, and the water inlet pipe 104 is fixedly connected to the side of the soaking tank 103. Both the water inlet pipe 104 and the drain pipe 105 are equipped with electronic control valves to control the opening and closing of the water inlet pipe 104 and the drain pipe 105. The drain pipe 105 is fixedly connected to the bottom of the soaking tank 103 to bear the load.

[0026] The lifting unit consists of a lifting assembly 201, a telescopic rod 202, a platform 203, and a fixing thread 204. The lifting assembly 201 is fixedly connected to the top of the base plate 101. The telescopic rod 202 is movably connected to the top of the lifting assembly 201 and extends into the interior of the immersion tank 103, facilitating the up-and-down movement of the flange ball valve to be tested. The platform 203 is fixedly connected to the top of the telescopic rod 202. The fixing thread 204 is located on the top of the platform 203 and plays the main lifting role. The connection unit consists of a support frame 211, an air compressor 212, a conduit 213, a connecting thread cover 214, a pressure sensor 215, and a control panel 216. The support frame 211 is fixedly connected to the base plate. At the top of 101, air compressor 212 is fixedly connected to the top of support frame 211, conduit 213 is fixedly connected to the top of air compressor 212, connecting threaded cap 214 is fixedly connected to the other end of conduit 213, pressure sensor 215 is disposed inside connecting threaded cap 214 and pressure sensor 215, control panel 216 is fixedly connected to the top of support frame 211, pressure sensor 215, air compressor 212 and lifting assembly 201 are electrically connected to control panel 216, so that pressure sensor 215, air compressor 212 and lifting assembly 201 can be driven to work through control panel 216, playing the main connecting role, and can fill the flange ball valve to be tested with compressed air.

[0027] In use, the flange ball valve to be tested is installed on the platform 203 via the fixing thread 204. The control panel 216 drives the lifting assembly 201, causing the telescopic rod 202 to lower the platform 203 and the flange ball valve into the soaking tank 103. Then, water is injected into the soaking tank 103 through the water inlet pipe 104 (the electronic control valve of the water inlet pipe 104 is open). After the water submerges the flange ball valve, the electronic control valve of the water inlet pipe 104 is closed.
