Abstract
Description
Technical Field
[0001] This invention relates to the field of helium leak detection chamber pipeline assembly technology, specifically a helium leak detection chamber protective pipeline assembly with strong sealing and shielding performance. Background Technology
[0002] Helium mass spectrometry leak detectors are a common analytical instrument widely used both domestically and internationally, in industries such as power, vacuum, nuclear, and refrigeration. Using helium as the leak indicator gas, they are specifically designed for leak detection and are the most common leak detection instrument in vacuum leak detection technology. When performing vacuum helium testing on objects, the helium testing equipment and the operating room are usually isolated and separate. Therefore, the pipelines on the helium testing equipment need to be connected through protective components.
[0003] Currently, when performing helium leak testing on items, the helium leak detector is usually placed in a shielded room, and the instrument is operated through the shielded room's control room. Since the walls separating the two rooms are quite thick, a pipeline protection assembly needs to be installed in the middle of the wall to connect the instrument to the control table. However, the existing pipeline assembly has poor sealing performance and is inconvenient to install. Furthermore, the pipeline assembly does not have radiation shielding function, which can cause physical harm to personnel who operate for extended periods. Summary of the Invention

[0008] A sealing component is provided in the middle of the mounting base, and a compression component is provided in the middle of the support base. The compression component is mainly used to compress the internal gas and work in conjunction with the sealing component to achieve the effect of sealing the conduit. A shielding component is fixedly installed on one side surface of the mounting base. The shielding component is mainly used to shield the radiation generated by the conduit.

[0011] Furthermore, the sealing assembly includes a sealing ring and an air storage chamber. The air storage chamber is located in the middle of the mounting base, and the sealing ring is fixedly installed on the inner side wall of the mounting base. The surface of the mounting base is provided with an air guide hole, which communicates with the air storage chamber.
[0012] Furthermore, the sealing ring is circular in shape and is made of rubber material with good shrinkage properties.
[0013] Furthermore, the compression assembly includes a compression cylinder, a compression chamber, and a positioning spring. The compression cylinder is fixedly installed on the inner wall of the support base, the compression chamber is located in the middle of the compression cylinder, and the positioning spring is fixedly installed on the inner top wall of the compression chamber.
[0014] Furthermore, the compression assembly also includes a piston, a connecting column, and a drag ring.

[0017] Furthermore, the shielding assembly also includes a tube and a socket, the tube being inserted into the inner wall of the shielding ring, and the socket being located in the middle of the tube.
[0018] (III) Beneficial Effects
[0019] The present invention has the following beneficial effects:
[0020] 1. This helium leak detection chamber protective pipeline assembly with strong sealing and shielding performance achieves rapid installation by passing the shielding pipe through the wall between the shielding chamber and the shielding operating room. The mounting base is then fixed to the wall surfaces of the operating room and the shielding chamber respectively through wall nails and mounting holes. The threaded rod is then rotated to screw it into the threaded hole of the positioning nut. At the same time, the slider moves along the outside of the threaded rod. As the threaded rod screws in, the slider, along with the connecting block and pressure ring, clamps and fixes the pipeline.
[0021] 2. This helium leak detection chamber protection pipeline assembly with strong sealing and shielding performance uses a pipeline to compress a drag ring. The drag ring drives the connecting column and piston to compress the gas inside the compression chamber, increasing the pressure inside the gas storage chamber. This causes the sealing ring to expand and fit against the outer surface of the pipeline, thus sealing the insertion hole and ensuring the pipeline's airtightness. Furthermore, the combined use of the shielding tube, shielding ring, and pipeline achieves the effect of radiation shielding.
[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] Please see Figure 1-8 The present invention provides a technical solution: a helium leak detection chamber protective pipeline assembly with strong sealing and shielding performance, including a mounting base 1, a mounting hole 2 is provided on the surface of the mounting base 1, a limiting groove 6 is provided on the surface of the mounting base 1, a pressing component is provided inside the limiting groove 6, the pressing component is mainly used to fix and clamp the pipeline, and a support base 5 is provided on the surface of the mounting base 1.
[0035] A sealing component is provided in the middle of the mounting base 1, and a compression component is provided in the middle of the support base 5. The compression component is mainly used to compress the internal gas and work in conjunction with the sealing component to achieve the effect of sealing the conduit. A shielding component is fixedly installed on one side surface of the mounting base 1. The shielding component is mainly used to shield the radiation generated by the conduit.
[0036] Specifically, the pressing assembly includes a pressure ring 3, a connecting block 4, a slider 18, a threaded rod 16, and a positioning nut 17. The slider 18 is movably installed on the inner wall of the limiting groove 6, the threaded rod 16 is movably installed on the inner wall of the slider 18, the connecting block 4 is fixedly installed on the top surface of the slider 18, the positioning nut 17 is fixedly installed on the outer side of the mounting base 1, and the pressure ring 3 is fixedly installed on the inner surface of the connecting block 4.
[0037] In this embodiment, the pressure-holding component is mainly used to clamp the pipeline. By rotating the threaded rod 16, it is made to screw into the threaded hole of the positioning nut 17. At the same time, the slider 18 will also move along the outside of the threaded rod 16. As the threaded rod 16 screws in, the slider 18 will clamp and fix the pipeline with the connecting block 4 and the pressure ring 3.
[0038] Specifically, one end of the slider 18 is provided with a threaded hole, wherein the thread on the outer side of the threaded rod 16 is threadedly connected to the threaded groove on the side wall of the threaded hole in the middle of the slider 18.
[0039] In this embodiment, the threaded hole is mainly used to cooperate with the threaded rod 16. By rotating the threaded rod 16, the slider 18 is driven to move along the inner wall of the threaded rod 16.
[0040] Specifically, the sealing assembly includes a sealing ring 7 and an air storage chamber 19. The air storage chamber 19 is located in the middle of the mounting base 1. The sealing ring 7 is fixedly installed on the inner side wall of the mounting base 1. The surface of the mounting base 1 is provided with an air guide hole, which communicates with the air storage chamber 19.
[0041] In this embodiment, the sealing component is mainly used to wrap and seal the pipeline. Gas is injected into the gas storage chamber 19 to cause the sealing ring 7 to expand, thereby making it fit against the outside of the pipeline to achieve the sealing effect.
[0042] Specifically, the sealing ring 7 is circular in shape and is made of rubber material with good shrinkage properties.
[0043] In this embodiment, the sealing ring 7 is mainly used to make the sealing ring deformable and fit against the surface of the pipeline, thereby ensuring the airtightness of the shielding room.
[0044] Specifically, the compression assembly includes a compression cylinder 12, a compression chamber 11, and a positioning spring 13. The compression cylinder 12 is fixedly installed on the inner wall of the support base 5, the compression chamber 11 is opened in the middle of the compression cylinder 12, and the positioning spring 13 is fixedly installed on the inner top wall of the compression chamber 11.
[0045] In this embodiment, the compression component is mainly used to compress the gas inside the compression chamber 11, thereby triggering the sealing component.
[0046] Specifically, the compression assembly also includes a piston 15, a connecting column 14, and a drag ring 9. The piston 15 is movably mounted on the inner wall of the compression chamber 11, the connecting column 14 is fixedly mounted on the top of the piston 15, and the drag ring 9 is fixedly mounted on the top of the connecting column 14.
[0047] In this embodiment, the cable is placed on the surface of the drag ring 9, and then the drag ring 9 is squeezed and clamped by the pressure ring 3, thereby driving the connecting column 14 and the piston 15 to move along the inside of the compression chamber 11 to compress the gas inside the compression chamber 11.
[0048] Specifically, the size of the positioning spring 13 is smaller than that of the compression cylinder 12, and the other end of the positioning spring 13 is fixedly connected to the top surface of the piston 15, wherein the piston 15 is initially in its original length state.
[0049] In this embodiment, the positioning spring 13 is mainly used to pull and reset the piston 15.
[0050] Specifically, the shielding assembly includes a shielding tube 20, a copper ring 22, and a shielding ring 23. The shielding tube 20 is fixedly installed on one side surface of the mounting base 1, the copper ring 22 is inserted into the inner wall of the shielding tube 20, and the shielding ring 23 is inserted into the inner wall of the copper ring 22.
[0051] In this implementation plan, the shielding components are mainly used to reduce and shield the radiation generated by the conduit and helium detector, thereby ensuring that operators are exposed to less radiation.
[0052] Specifically, the shielding assembly also includes a tube 8 and a socket 21. The tube 8 is inserted into the inner wall of the shielding ring 23, and the socket 21 is located in the middle of the tube 8.
[0053] In this implementation scheme, the socket 21 is mainly used for inserting pipelines.
[0054] In use, the shielding tube 20 is passed through the wall between the shielding room and the operating room of the shielding room. Then, the mounting base 1 is fixed to the wall surface of the operating room and the shielding room respectively through wall nails and mounting holes 2. Then, the pipeline is passed through the insertion hole 21. After the pipeline passes through the insertion hole 21, the sliding block 18 is driven to move along the inner wall of the limiting groove 6 and the outer side of the threaded rod 16 by rotating the threaded rod 16. The threaded hole is mainly used to cooperate with the threaded rod 16. By rotating the threaded rod 16, the sliding block 18 is driven to move along the inner wall of the threaded rod 16, thereby driving the pressure ring 3 to squeeze and clamp the pipeline. As the pressure ring 3 clamps the pipeline, one side of the pipeline will squeeze the drag ring 9. As the squeezing force on the drag ring 9 increases, the drag ring 9 will drive the connecting column 14 and the piston 15 to move, thereby... The gas inside the compression chamber 11 is compressed, and then the gas inside the compression chamber 11 is transported to the gas storage chamber 19 through the air guide column 10. The air guide column 10 on one side of the support base 5 is inserted into the air guide hole opened on the surface of the mounting base 1, and a sealing ring is sleeved on the outer surface of the air guide column 10 to ensure sealing. As the gas pressure inside the gas storage chamber 19 gradually increases, the sealing ring 7 will expand under the action of the gas pressure and fit tightly against the surface of the conduit, thereby sealing the inner wall of the insertion hole 21. When the threaded rod 16 is screwed into the maximum position through the threaded hole of the positioning nut 17, the pressure ring 3 clamps the conduit to the maximum position. The shielding tube 20, copper ring 22 and shielding ring 23 are mainly used to shield the high radiation generated in the operating room and shielding room and prevent its propagation, thereby ensuring the health of the operators.
