Description

Technical Field

[0001] This utility model relates to the field of metal pipe testing technology, and in particular to a metal pipe sealing testing device. Background Technology

[0002] Metal pipes are hollow, long, strip-shaped metal products, mainly made of metal materials. They are typically circular in shape and are manufactured by rolling and welding steel strips and plates. Straight seam welded steel pipes are made by rolling steel plates longitudinally and then welding them into a tubular shape, while spiral seam welded steel pipes are made by spirally rolling and welding steel strips. Metal pipes have wide applications in various fields. In the construction industry, they are used for water supply and drainage, heating pipes, and fire protection pipes. Metal pipes have a long service life and are not easily damaged. In the industrial field, they are used to transport various chemical raw materials and gases, and can also be used as hydraulic and lubrication pipelines to ensure the normal operation of various machinery.

[0003] A search revealed Chinese Patent Publication No. CN209589357U, which discloses a metal pipe sealing performance testing device. The device includes a base plate, a testing device body located on the top left side of the base plate, a water tank fixedly connected to the top of the testing device body, a pressurized water pipe connected to the right side of the testing device body, and a metal pipe body movably connected to the right side of the pressurized water pipe. Turntables are fixedly connected to the top and bottom of the left side of the pressurized water pipe. This invention utilizes a base plate, testing device body, water tank, metal pipe body, turntable, rotating rod, and rotating disk. The combination of the rotating rod, transmission frame, sliding sleeve, lifting plate, lifting column, limit plate, clamping rod, positioning bolt, first sealing ring, and pressurized water pipe allows the first sealing ring to seal the right end of the metal pipe body. The user opens the detection device body, and the detection device body introduces water from the water tank into the pressurized water pipe. The pressurized water pipe then introduces water into the metal pipe body to pressurize it. However, the above structure uses water pressure to test the seal of the metal pipe, which can damage the metal pipe. The concentrated water pressure can cause the weld to crack, and the water can also corrode the metal pipe. Utility Model Content

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, a sealing component is installed on the sliding block along the axial direction of the metal tube to be tested. The sliding block can slide on the slide rail and is applicable to metal tubes of various lengths. Two sealing components are used to seal both ends of the metal tube to be tested. The right sealing component is connected to the air supply component and has an air pressure detection component. The two sealing components block both ends of the metal tube to be tested under the action of the cylinder. The air supply component provides gas with a preset pressure from the left end to the right end of the metal tube to be tested. The air pressure detection component can determine whether the metal tube is leaking based on the detected air pressure value. If there is a leak, the linkage rod drives the lower limit block to rotate backward, causing the metal tube to fall into the defective area in front. If there is no leak, the linkage rod drives the lower limit block to rotate forward, causing the metal tube to fall into the good area in the rear. This realizes the sealing detection and classification of the metal tube, and can detect a large number of metal tubes in a short time, greatly reducing labor costs.

[0031] 2. In this utility model, the metal tube to be tested is placed above the side plate. The blocking block prevents the metal tube from rolling down. The motor drives the rotating shaft to rotate, and the actuating block also rotates. The small protrusion of the actuating block pushes the metal tube, so that the metal tube rolls down between the side plate and the limiting plate in an orderly manner. The raising and lowering of the telescopic block ensures that only one metal tube falls into the detection mechanism at a time. The distance between the bottom surface of the limiting plate and the top surface of the side plate allows only one metal tube to pass through. Finally, the guide block guides the tube to the space between the two side limiting blocks for detection, realizing orderly and accurate feeding for detection. This allows the detection equipment to work continuously and stably, improves detection efficiency, and reduces detection time. Attached Figure Description
