Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for PE pipe production, in particular to an air compressor device for PE pipe production. Background Art

[0002] PE pipe is a high-quality pipe with good flexibility, strong impact resistance and wear resistance. It is also light in weight, easy to carry and has a simple welding process. Therefore, it is widely used in the transportation of coal gas, oil and natural gas. Its raw material is PE resin, which is polymerized from the monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins of different densities can be obtained. Therefore, PE pipes need to be tested for air tightness after production.

[0003] The patent with announcement number CN217605209U discloses a sealing detection device for PE water supply pipes, including a detection box, a support plate is arranged on the inner top of the detection box, and a rotating shaft is fixedly connected to the side walls at both ends of the support plate. The beneficial effect of the utility model is: by opening a plurality of sealing ring grooves of different diameters on the adjacent plate walls of the two clamping plates, the clamping plates can be suitable for sealing PE water supply pipes of various sizes and models. However, using a seal to squeeze and seal the two ends of the PE pipe will cause the PE pipe to deform, causing the contact surface between the PE pipe and the seal to tilt, affecting the sealing performance, and increasing the possibility of damage to the PE pipe. Therefore, an air compressor device for PE pipe production is urgently needed to solve the above problems. Utility Model Content

[0031] In this embodiment, in actual use, the second sealing cylinder 18 is pressed against the other end of the PE pipe, and air is injected into the PE pipe by the air compressor 2 using the second sealing cylinder 18 to perform an air tightness test. The air tightness of the PE pipe can be detected by setting a pressure gauge 20. The setting of the valve 19 ensures that there is no internal pressure release during the PE pipe test, thereby ensuring the accuracy of the test.

[0032] Specifically, refer to Figure 2 The top of the testing table 3 is fixedly connected to a lower support seat 8, an upper support seat 9 is arranged on the top of the lower support seat 8, a connecting block 10 is fixedly connected to the front of the upper support seat 9, a connecting seat 11 is fixedly connected to the front of the lower support seat 8, a clamping block 12 is fixedly connected to the bottom of the connecting block 10, a clamping assembly for limiting the clamping block 12 is arranged inside the connecting seat 11, a docking groove is opened inside the connecting seat 11, the clamping block 12 is inserted into the inside of the docking groove, there are two connecting blocks 10, and the two connecting blocks 10 are symmetrically distributed on the front and back sides of the upper support seat 9.
