Description
Technical Field
[0001] This utility model belongs to the technical field of electron accelerator accessories, specifically relating to an electron accelerator pipeline connection structure. Background Technology
[0002] With economic development and social progress, electron accelerator irradiation sterilization has begun to attract attention. An electron accelerator irradiation device is a unit that generates, accelerates, and extracts electron beams for radiation processing. It consists of a beam generation device, an acceleration device, an extraction device, and a control system. During installation, electron accelerators require cooling water lines, typically constructed using copper tubing. The cooling water system in an electron accelerator primarily functions to dissipate heat, maintain thermal stability, and remove heat generated by secondary radiation; its operation is crucial to the normal functioning of the entire system. During the installation of cooling water pipes, due to the location and size of other components in the electron accelerator and the cooling requirements of some components, the cooling water piping often has complex layouts and bends. When handling these bends, some installers resort to bending or cutting the copper tubing. This not only affects installation efficiency but also compromises the mechanical strength of the copper tubing, creating potential hazards for the operation of the cooling system.
[0003] Therefore, based on the above issues, it is necessary to optimize the pipeline design of the cooling water system to improve the overall installation efficiency of the equipment while ensuring the stable operation of the cooling water system. Utility Model Content
[0004] This invention provides an electron accelerator pipeline connection structure to solve at least one of the above-mentioned technical problems.
[0005] The technical solution adopted by this utility model is as follows: an electron accelerator pipeline connection structure, including a pre-fabricated tube and a connector. The pre-fabricated tube has a radially recessed groove near its end. The connector has a plurality of radially extending ball grooves on its inner side near its end. Each ball groove has a limiting ball that mates with the groove. The connector has an axially extending sliding groove on its inner side near the ball groove. A sliding block is slidably connected in the sliding groove. The end of the sliding block facing the ball groove has a covering ring that blocks the ball groove, so that the limiting ball falls into the groove after the sliding block is pushed to move by inserting the pre-fabricated tube into the end of the connector.
[0006] In a preferred embodiment, the prefabricated pipe includes a prefabricated straight pipe with straight ends, a prefabricated bent pipe, or a prefabricated irregular pipe.
[0007] In a preferred embodiment, the connector is a straight connector, elbow, or irregular connector comprising two connectors that connect to the precast pipe ends.
[0008] In a preferred embodiment, a transition chamfer is formed at the connection between the groove and the precast tube.
[0009] In a preferred embodiment, a push spring is provided between the limiting ball and the ball groove.
[0010] In a preferred embodiment, the ball groove is configured as a ball hole penetrating the connector, a ball-retrieving plug is connected to the ball hole, and the ball-pushing spring is located between the ball-retrieving plug and the limiting ball.
[0011] In a preferred embodiment, the bead picker is threadedly connected to the connector, and the top of the bead picker has an internal hexagonal groove.
[0012] In a preferred embodiment, a return spring is provided at the end of the sliding block facing away from the ball groove, and the end of the return spring facing away from the sliding block makes a stop contact with the sliding groove.
[0013] In a preferred embodiment, the sliding block has a clearance groove that cooperates with the return spring, so that when the sliding block moves in the direction of the return spring, its end makes a stop contact with the end of the sliding groove.
[0014] In a preferred embodiment, the two ends of the sliding block have a first sealing ring and a second sealing ring that mate with the end of the precast tube and the end of the sliding groove, respectively, and the inner end of the connector is provided with a sealing gasket extending to the ball groove.
[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0016] 1. As a preferred embodiment of this utility model, by incorporating the cooling water pipeline into the structural design of the electron accelerator, the length, dimensions, and direction of the pipeline are pre-designed, and the pipeline is divided into multiple prefabricated pipes and prefabricated connectors based on the design results. During the assembly and installation of the electron accelerator, assembly can be carried out according to the preset pipeline path, thereby significantly reducing the pipeline adjustment time during on-site installation and improving the overall installation efficiency.
[0017] 2. In a preferred embodiment of this utility model, the prefabricated pipe pushes the sliding block to move, and during the movement, the covering ring moves away from the ball groove. At this time, the limiting ball in the ball groove falls into the groove of the prefabricated pipe, thereby completing the connection between the prefabricated pipe and the connector. This connection method can significantly improve the efficiency of the connection work, thereby reducing the overall installation time of the pipeline.
[0018] 3. In a preferred embodiment of this utility model, the elastic force of the push ball spring during the deformation recovery process forces the limiting ball into the groove of the precast tube, thereby facilitating the locking of the precast tube and the connector. At the same time, due to the pushing force of the push ball spring, the limiting ball cannot return from the groove to the ball groove, thereby preventing the precast tube from falling off the connector and achieving a tight connection between the two.

[0031] A preferred embodiment, such as Figure 1 As shown, an electron accelerator piping connection structure includes prefabricated pipes 1 and connectors 2. When designing the electron accelerator structure, the cooling water piping is incorporated into the structural design. The length, dimensions, and direction of the piping are pre-designed, and based on the design results, the piping is divided into multiple prefabricated pipes 1 and prefabricated connectors 2. The prefabricated pipes 1 include prefabricated straight pipes, prefabricated bends, or prefabricated irregular pipes with straight ends. The connectors 2 include two straight connectors, elbows, or irregular connectors that connect to the ends of the prefabricated pipes 1. During the assembly and installation of the electron accelerator, assembly can be performed according to the pre-set piping path, thereby significantly reducing the pipeline adjustment time during on-site installation and improving overall installation efficiency.
[0032] Specifically, refer to Figure 1 , Figure 2 and Figure 3The precast tube 1 has a radially recessed groove 10 near its end. The connector 2 has a plurality of radially extending ball grooves 20 on its inner side near its end. Preferably, there are two ball grooves 20, which are coaxially arranged. Each ball groove 20 has a limiting ball 21 that cooperates with the groove 10. The connector 2 has an axially extending sliding groove 22 on its inner side near the ball groove 20. A sliding block 23 is slidably connected in the sliding groove 22. The end of the sliding block 23 facing the ball groove 20 has a covering ring 231 that blocks the ball groove 20. The limiting ball 21 falls into the groove 10 after the sliding block 23 is pushed to move by inserting the precast tube 1 into the end of the connector 2. In this invention, the prefabricated pipe 1 and connector 2 are connected simply by inserting the prefabricated pipe 1 into the connector 2. During insertion, the prefabricated pipe 1 pushes the sliding block 23, causing the covering ring 231 to move away from the ball groove 20. At this time, the limiting ball 21 in the ball groove 20 falls into the recessed portion 10 of the prefabricated pipe 1, thus completing the connection between the prefabricated pipe 1 and the connector 2. This connection method significantly improves the efficiency of the connection process, thereby reducing the overall installation time of the pipeline.
[0033] Furthermore, a transition chamfer is formed at the connection between the groove 10 and the precast tube 1. The transition chamfer facilitates the insertion of the precast tube 1 into the connector 2.
[0034] Furthermore, a push spring 24 is provided between the limiting ball 21 and the ball groove 20. For example... Figure 2 As shown, the push ball spring 24 is in a compressed state when the preformed tube 1 is not inserted. When the preformed tube 1 is inserted, the preformed tube 1 pushes the sliding block 23 to move. After the cover ring 231 releases the obstruction of the limiting ball 21, the push ball spring 24 will force the limiting ball 21 into the groove 10 of the preformed tube 1 during the process of restoring its deformation. This facilitates the locking of the preformed tube 1 and the connector 2. At the same time, due to the pushing force of the push ball spring 24, the limiting ball 21 cannot return to the ball groove 20 from the groove 10, thereby preventing the preformed tube 1 from falling off the connector 2 and achieving a tight connection between the two.
[0035] Furthermore, the ball groove 20 is configured to pass through the ball hole of the connector 2, and a ball-retrieving plug 25 is connected to the ball hole. A ball-pushing spring 24 is located between the ball-retrieving plug 25 and the limiting ball 21. The ball-retrieving plug 25 is threadedly connected to the connector 2, and an internal hexagonal groove is formed on the top of the ball-retrieving plug 25. When it is necessary to disassemble the prefabricated tube 1 and the connector 2, the ball-retrieving plug 25 can be removed, and the ball-pushing spring 24 and the limiting ball 21 can be taken out, thereby releasing the limiting effect of the connector 2 on the prefabricated tube 1.
[0036] Furthermore, a return spring 26 is provided at the end of the sliding block 23 facing away from the ball groove 20, and the end of the return spring 26 facing away from the sliding block 23 makes a stop contact with the sliding groove 22. The return spring 26 can be compressed when the pre-made tube 1 is inserted, thereby storing elastic potential energy. After the pre-made tube 1 is removed, it moves to its original position under the action of elastic force and continues to block and cover the ball groove 20.
[0037] Furthermore, a clearance groove 232 is formed on the sliding block 23 to cooperate with the return spring 26, so that when the sliding block 23 moves in the direction of the return spring 26, its end makes a stop contact with the end of the sliding groove 22. The clearance groove 232 provides movement space for the compression of the return spring 26, and at the same time, it can limit the stroke of the sliding block 23 by contacting the bottom of the sliding groove 22 during the movement of the moving block. In addition, the thrust of the return spring 26 during the recovery of deformation can make the sliding block 23 and the end of the prefabricated tube 1 fit tightly together, which helps to ensure the sealing of the connection between the prefabricated tube 1 and the connector 2.
[0038] Furthermore, the sliding block 23 has a first sealing ring 27 and a second sealing ring 28 at both ends, which mate with the end of the precast pipe 1 and the end of the sliding groove 22, respectively. The inner end of the connector 2 is provided with a sealing gasket 29 extending into the ball groove 20. The sealing rings and sealing gasket 29 provide multiple guarantees for its airtightness and watertightness, ensuring both connection efficiency and connection reliability.
