Description
Technical Field
[0001] This utility model relates to the field of pipeline sealing test technology, specifically a pipeline sealing test device. Background Technology
[0002] Water supply and drainage pipes are an important building material in construction. Due to the characteristics of water transportation, water supply and drainage pipes require high sealing performance. Therefore, in actual production activities, water supply and drainage pipes are generally sampled and tested for sealing performance after production.
[0003] Chinese utility model patent CN219416589U discloses a water supply and drainage pipe sealing test device, including a support base, a test water tank at the top of the support base, a water supply and drainage pipe body inside the test water tank, a sealing test component for sealing test on the water supply and drainage pipe body, and a lifting clamping component for fixing the water supply and drainage pipe body at the bottom. The device includes a test water tank, a water supply and drainage pipe body inside the test water tank, and a sealing test component for sealing test on the water supply and drainage pipe body. The bottom of the main body is equipped with a lifting clamping assembly for fixing the water supply and drainage pipe body. During pipe sealing testing, workers seal both ends of the drainage pipe body with the side sealing cap, outer pipe wall sealing gasket, and inner pipe wall sealing gasket. Then, the pipe is moved into the testing tank via the lifting clamping device. Water is then added to the testing tank, and air is pumped into the drainage pipe for testing. However, the side sealing cap, outer pipe wall sealing gasket, and inner pipe wall sealing gasket can only effectively seal a single specification of drainage pipe. When testing different specifications of pipes, workers need to replace different sealing components, limiting its applicability. Therefore, we propose a pipe sealing testing device.
