Description

Technical Field

[0001] This utility model belongs to the field of PE pipe pressure resistance testing technology, and more specifically, it relates to a PE pipe pressure resistance testing device. Background Technology

[0002] The PE pipe pressure resistance tester is a device used to test the pressure resistance of polyethylene (PE) pipes. Its main function is to simulate the high pressure conditions that the pipeline may encounter in the actual use environment, and to check whether the pipe can withstand long-term pressure loads, so as to ensure its safety, reliability and service life under various conditions.

[0003] Currently, some PE pipe pressure testing devices first seal both ends of the PE pipe with a sealing component before injecting water into the pipe for pressure testing. However, because the inner wall of the PE pipe is smooth, if the sealing is not complete, the strong water pressure may spray out the sealing component, which could injure workers or damage the machine. In addition, if the PE pipe bursts during the testing process, the water inside the pipe will spray out rapidly. If it sprays onto live machinery, it may cause damage to the machinery.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a PE pipe pressure resistance testing device in order to achieve a more practical purpose. Utility Model Content

A sliding groove is provided on one side of the upper surface of the workbench, and a lead screw is rotatably connected within the sliding groove. A slider is threadedly connected to the outer periphery of the lead screw, and the upper surface of the slider is connected to the bottom surface of one of the support seats. A chamber is provided inside the workbench, and a dual-axis motor is installed at the bottom of the chamber. A pair of threaded rods are installed at both ends of the dual-axis motor. A pair of support rods are movably connected to both sides of the chamber. One end of each support rod has a threaded groove, and the other end of the threaded rod extends into and is threadedly connected to the threaded groove. A mounting bracket is installed on one side of the upper surface of each support rod, and a transparent baffle is installed at one end of the mounting bracket. A water injection port is provided on one side of one of the sealing components, and a water supply pipe is connected to one side of the water injection port. The other end of the water supply pipe is connected to the water injection mechanism.

[0007] Furthermore, the upper end face of the support base is provided with a connecting groove, and a bolt is installed on one side of the connecting groove.

[0011] Further, the upper end surface of the workbench is provided with a collection box below the transparent baffle.

[0012] Further, the end of the lead screw is provided with a rotating block penetrating through one side of the workbench.

[0013] Compared with the prior art, the utility model has the advantages of:

[0014] When the staff needs to detect the pressure resistance of the PE pipe, the sealing element at one end of the PE pipe is placed in one of the fixing seats, and then the rotating block is rotated to drive the lead screw to rotate, the lead screw drives the sliding block to move to one side through rotation, the sliding block drives one of the support seats to move to one side, the support seat drives the fixing seat to move to the direction of the sealing element at the other end of the PE pipe and fixes the sealing element, so that the installation before the detection of the PE pipe is completed, and vice versa, so that the PE pipe can be disassembled, thereby realizing the effect of quickly detecting the pressure resistance of the PE pipe, effectively preventing the sealing element from being sprayed due to excessive water pressure and causing personal injury, and through the cooperation of the connecting block, the connecting groove and the bolt, when the pressure resistance of the PE pipe of other sizes needs to be detected, the bolt is rotated to make the bolt separate from the threaded groove two, the fixing seat is taken out, then the corresponding fixing seat is replaced, the bolt is rotated again to move the end of the bolt to the threaded groove two, and the fixing seat is fixed, so that the product can adapt to the detection of PE pipes of various sizes, thereby improving the practicability of the product.

[0015] Through the cooperation of the double-shaft motor, the threaded rod, the threaded groove one, the support rod, the mounting frame, the transparent baffle and the collection box, when detecting, the double-shaft motor is started to drive a pair of threaded rods to rotate in the threaded groove one, so that a pair of support rods move to the middle, and a pair of transparent baffles move to the middle and adhere through a pair of mounting frames, if the PE pipe bursts during the detection process, the transparent baffle can effectively block the splashing of water, thereby effectively preventing the splashing water from falling on the electrified machine and causing damage to the machine, the blocked water falls into the collection box through the through groove for collection, thereby facilitating the staff to concentrate on processing, and thereby improving the convenience of the product.
