Description

Technical Field

[0001] This utility model relates to the field of special equipment manufacturing, and in particular to a quality inspection device for pressure pipelines of special equipment. Background Technology

[0002] In key industrial sectors such as petrochemicals, energy transmission, biomedicine, and metallurgy, special equipment pressure pipelines serve as the core transmission carriers for high-temperature, high-pressure, and high-risk media (such as flammable and explosive gases, toxic and harmful fluids, and corrosive media). Their airtightness is directly related to the operational safety of industrial systems and the safety of personnel and property. Currently, the airtightness testing of pressure pipelines for special equipment mainly employs techniques such as manual sealing testing, water pressure substitution testing, and fixed single-machine testing. However, considering the high-pressure operating conditions, special media characteristics, and stringent safety standards of these pipelines, most existing pressure pipelines are custom-produced. Although the quantity per batch is less than that of ordinary pipelines, testing is required for pipelines of different specifications and pressure ratings. Traditional single-station testing devices require individual loading, unloading, and debugging, resulting in a long testing cycle that cannot meet the timeliness requirements for mass production or maintenance of pressure pipelines for special equipment. Some multi-station devices, lacking a synchronous sealing structure designed for high-pressure conditions, experience pressure interference between stations, leading to seal failure under high pressure and resulting in inaccurate test results, thus failing to meet the high-precision testing requirements of pressure pipelines for special equipment. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special equipment pressure pipeline quality inspection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A special equipment pressure pipeline quality inspection device includes a base. Multiple equidistant fixed blocks are fixedly connected to the top of the base along its circumference. A sealing sleeve is fixedly connected to the top of each fixed block. A pipe workpiece is abutted against the top of the fixed block, and the sealing sleeve is adapted to the pipe workpiece. An L-shaped air inlet pipe is fixedly connected inside each fixed block, with its top penetrating the sealing sleeve and communicating with the pipe workpiece. A pressure plate is provided above the base. Multiple equidistant sealing grooves are formed at the bottom of the pressure plate, and these grooves are adapted to the pipe workpiece. Multiple equidistant air outlet pipes are fixedly connected to the pressure plate. A second air pump is fixedly connected to one end of each air outlet pipe extending beyond the top of the pressure plate, and the second air pump is fixedly connected to the pressure plate. A delivery hose is fixedly connected to the outlet of the second air pump.

[0005] As a further embodiment of this utility model: a gas storage seat is fixedly connected to the top of the base, and a plurality of equally spaced conduits are fixedly connected to the outer wall of the gas storage seat along its circumference, and the conduits are fixedly connected to the air inlet pipe, and the gas storage seat is fixedly connected to the delivery hose.

[0006] As a further improvement of this utility model: multiple pressure gauges are provided above the pressure plate at equal intervals, and the pressure gauges are fixedly connected to the air outlet pipe.

[0007] As a further improvement of this utility model: a through groove is provided on the pressure plate, and the conveying hose is located in the through groove.

[0008] As a further embodiment of this utility model: a mounting base is fixedly connected to one side of the base, a stud is rotatably connected inside the mounting base, a movable block is threadedly connected to the outer wall of the stud, and the movable block is fixedly connected to the pressure plate.

[0009] As a further embodiment of this utility model: a sliding groove is provided on the side of the mounting base near the pressure plate, and the inner wall of the sliding groove is slidably connected to the movable block; a motor is fixedly connected to the top of the mounting base, and the output shaft of the motor is fixedly connected to the sliding groove.

[0010] This utility model has the following beneficial effects: 1. In this utility model, when in use, the pipe workpiece is placed on the fixed block, so that the sealing sleeve is squeezed into the pipe workpiece. After multiple pipe workpieces are placed, the motor is started. The output shaft of the motor rotates, which drives the stud to rotate, causing the movable block to move down. In turn, the movable block drives the pressure plate to move down, so that the pipe workpiece enters the sealing groove at the bottom of the pressure plate, and the pipe workpiece is pressed and fixed. The first air pump is started. The first air pump delivers the compressed gas in the air storage seat to the pipe workpiece through the conduit and the air inlet pipe. The compressed gas flows to the pressure gauge through the air outlet pipe for pressure detection, which can detect the air tightness of the pipe workpiece, making it easy to operate. 2. In this utility model, after the test is completed, the first air pump is turned off and the second air pump is turned on. The second air pump delivers compressed gas to the gas storage base through the delivery hose for easy recovery. At the same time, the delivery hose prevents the second air pump from being unable to connect with the gas storage base after the pressure plate is raised or lowered. Attached Figure Description
