Description

Technical Field

[0001] This utility model relates to the field of compensator technology, specifically to a compensator pressure testing limit device. Background Technology

[0002] An expansion joint is actually a compensating element composed of a bellows (an elastic element) and accessories such as end pipes, supports, flanges, and conduits. It is also commonly known as an expansion joint or expansion expansion joint. The main function of an expansion joint is to absorb dimensional changes in pipelines, conduits, and containers caused by thermal expansion and contraction by utilizing the effective expansion and contraction deformation of the bellows, or to compensate for axial, lateral, and angular displacements of pipelines, conduits, and containers. In addition, expansion joints can also be used for noise reduction and vibration damping, and have wide applications in modern industry.

[0003] For example, application number CN202323261971.5, with an authorization announcement date of 20240719, describes a compensator pressure testing limiting device, which relates to the field of testing tooling technology. The compensator pressure testing limiting device includes a support frame and a connecting frame. Two support frames are provided, each positioned at one end of the compensator's end protrusions to support them. The connecting frame is positioned between the two support frames, fixing the distance between them to fix the compensator's expansion and contraction. The support frame includes a U-shaped frame and a connecting block at the top of the U-shaped frame. A U-shaped groove on the U-shaped frame is used to accommodate the end protrusions of the compensator. The connecting block is placed on the top of the U-shaped frame, sealing the opening of the U-shaped groove. The connecting block is detachably connected to the U-shaped frame.

[0004] During the production of compensators, pressure tests are required. During the test, the compensator can extend uncontrollably to both ends. If no fixing or limiting is applied, the expansion joint of the compensator may break or continuously deform and lose stability, or even tear, causing unpredictable damage. To solve this problem, existing technologies use limiting devices to limit the compensator. However, the limiting process requires multiple adjustments, which is cumbersome. Therefore, it is urgent to design a pressure testing limiting device for compensators to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pressure testing limit device for compensators to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pressure testing limiting device for a compensator includes a fixed component, a movable component slidably connected inside the fixed component, a base, an installation area on one side of the top outer wall of the base, two sliding rods mounted inside the installation area by bolts, a lead screw mounted inside the installation area by bearings, a groove on one side of the outer wall of the base, a drive motor mounted on one side of the inner wall of the groove by bolts, the output end of the drive motor being fixedly connected to one end of the lead screw by a flat key, and the movable component being slidably connected to the outside of the two sliding rods, with a transmission connection between the movable component and the lead screw.

[0008] Furthermore, a power source is bolted to one side of the inner wall of the groove, and the power source is electrically connected to the drive motor via a wire.

[0009] Furthermore, a fixing seat is installed on one side of the top outer wall of the base by bolts, and a water inlet pipe is inserted into one side of the fixing seat outer wall.

[0010] Furthermore, a housing is bolted to one side of the outer wall of the fixed base, a door is bolted to one side of the outer wall of the housing, and a pump body is bolted to one side of the bottom inner wall of the housing.

[0011] Furthermore, a support plate is bolted inside the housing, and a controller is bolted to the top outer wall of the support plate. The controller is electrically connected to a power source via a wire.

[0012] Furthermore, the movable component includes a slide block slidably connected to the outside of two slide rods, and the slide block is threadedly connected to the outside of a lead screw.

[0013] Furthermore, a limiting seat is welded to one side of the top outer wall of the slide block, and a stepped groove is provided on one side of the outer wall of the limiting seat and the fixing seat. A rubber airbag is provided inside the stepped groove, and the rubber airbag is connected to the pump body through a pipe.

[0014] In the above technical solution, the compensator pressure testing limit device provided by this utility model has the following beneficial effects:

[0015] By using the lead screw, slide bar, and drive motor, when the compensator needs to be limited by this device, the drive motor can be started. The drive motor will drive the lead screw to rotate, and the rotating lead screw will cause the moving component to slide on the slide bar. The movement of the moving component can cooperate with the fixed seat to quickly limit the compensator, reducing the difficulty of limiting and fixing the compensator and increasing the speed of fixing the compensator by operating the limit device.

[0016] The stepped groove design facilitates the fixing of compensators of different diameters by the limiting seat and the fixing seat, greatly improving the practicality of the device.

[0017] By installing one end of the compensator inside the stepped groove using the pump body and rubber airbag, the pump body can be activated. The pump body will draw air into the rubber airbag, causing the rubber airbag to inflate and wrap around the compensator, thus fixing the compensator circumferentially and ensuring the firmness between the compensator and the stepped groove.
