Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline pressure-pressing, in particular to a pipeline pressure-pressing device for water supply network construction. Background Art

[0002] The water supply network is a pipeline system for transporting and distributing water to users in water supply projects. The water supply pipeline needs to be pressure tested after connection to determine whether the water supply pipeline connection is reliable. During the pressure test, check the joints, female thread joints and plugs one by one to ensure that there is no water seepage, otherwise it will directly affect the needle of the pressure tester. If the needle of the pressure tester does not drop at all or the drop is less than 0.1 within the specified time, it means that the water supply pipeline is good.

[0003] In contrast, a Chinese patent with authorization announcement number CN217276748U discloses a more efficient pipe pressure-testing device for water supply network construction, including a pressure-testing pipe and a test pipe. The outer wall of the pressure-testing pipe is provided with a circular plate, and a conical rubber block is provided on the right side of the circular plate. The output end of the pressure-testing pipe passes through the conical rubber block to the test pipe. The outer wall of the circular plate is provided with symmetrically distributed fixed convex plates, and screw rods are provided on the right sides of the two fixed convex plates. The two screw rods are commonly connected to a circular ring, and the top of the outer wall of the circular ring is threadedly connected to a fastening screw, and the bottom of the outer wall of the circular ring is also threadedly connected to a fastening screw, and the outer walls of the two screw rods are threadedly connected to fastening blocks.

[0004] The above patent can fix the ring and the test tube by setting a fastening screw, and then move the ring toward the circular plate by the fastening block and the screw rod, so that the test tube and the conical rubber block fit tightly, solving the problem that the pressure tube and the pipe to be tested may be separated during the pressure test. However, when fixing the test tube, it is necessary to tighten multiple fastening screws one by one, which is cumbersome. Therefore, a new device should be designed. Utility Model Content

After the test is completed, the bayonet 206 under the connecting plate 207 is pulled out through the handle 208 to release the restriction on the sliding sleeve 204, and the sliding sleeve 204 is made to slide along the slide bar 202 to the side of the fixed plate 201, thereby releasing the clamping state of the clamping assembly;
