Technical Field

[0001] This utility model relates to the technical field of cleanroom engineering technology assurance, and more specifically, to a process water through-plate connector for cleanrooms in bioproduct workshops. Background Technology

[0002] In the production activities of cleanrooms in biopharmaceutical workshops, high cleanliness requirements are generally placed on facilities, equipment, and the environment. Because the process pipelines in the production equipment and technical corridors of cleanrooms in biopharmaceutical workshops need to be interconnected to ensure the flow of process water, but due to the limitations of the cleanroom infrastructure structure, various process pipelines need to be connected through walls to meet the needs of production activities.

[0003] In existing technologies, gaps are left after pipes pass through the plate. These gaps can only be filled with foam or sealed with glue. However, this cannot guarantee the cleanliness requirements of the cleanroom for a long time, and it is also unsightly. Furthermore, it is quite troublesome to disassemble the pipes when maintenance and cleaning are needed later. Utility Model Content

[0004] The purpose of this invention is to provide a process water through-plate connector for cleanrooms in biopharmaceutical workshops, aiming to solve the problem of inadequate sealing in existing cleanrooms for biopharmaceutical workshops.

[0006] The tubular body has a positioning ring that extends radially outward in the middle. The positioning ring is arranged between the fastening structure and the chuck. The positioning ring has a sealing surface that is arranged forward for abutting against the wall panel.

[0007] Furthermore, the connection structure includes a threaded section arranged circumferentially along the tubular body.

[0008] Furthermore, the threaded segment is arranged circumferentially around the outer periphery of the tubular body.

[0009] Furthermore, the fastening structure includes a fastening washer and a fastening nut, which are sequentially fitted onto the rear part of the threaded section.

[0010] Furthermore, the tubular body has a limiting ring that extends radially outward in the middle, and the limiting ring has a limiting surface that faces forward; the limiting surface has a limiting ring groove formed by a recess, and the limiting ring groove is arranged around the circumference of the limiting surface, and a limiting sealing ring is provided in the limiting ring groove.

[0011] Furthermore, the chuck is fixedly connected to the end of the tubular body by welding.

[0012] Furthermore, the chuck has a rearwardly arranged annular surface, on which a downwardly recessed annular groove is provided, the annular groove being arranged circumferentially around the annular surface.

[0013] Furthermore, the tubular body has a flow channel that runs through both the front and rear ends, and the inner wall of the flow channel is mirror-polished to a smooth state.

[0014] Furthermore, the outer circumferential diameter of the sealing surface is consistent with the outer circumferential diameter of the fastening gasket.

[0015] Furthermore, the chuck is conical, and the positioning ring is conical;

[0016] The contact surface is provided with an annular elastic layer, which completely covers the contact surface.

[0017] Compared with existing technologies, the process water through-plate connector for cleanrooms in biopharmaceutical workshops provided by this utility model uses a chuck design to connect the equipment pipelines of the cleanroom to the tubular body. Then, through the design of the connection structure, it connects the process pipelines in the technical channel to the tubular body, thereby achieving the connection of production equipment and process pipelines in the technical channel of the seed production workshop cleanroom.

[0023] Reference Figures 1-2 The image shown is a preferred embodiment of the present invention.

[0024] The process water through-plate connector for cleanrooms in bioproduct workshops provided by this utility model includes a tubular body 100. The front of the tubular body 100 is provided with a connection structure for connecting to an external pipe. The middle of the tubular body 100 is provided with a fastening structure for fastening the process water through-plate connector to a wall panel, and a chuck 400 is provided at the rear of the tubular body 100 with a quick-install clamp connector.

[0025] The tubular body 100 has a positioning ring 500 that extends radially outward in the middle. The positioning ring 500 is arranged between the fastening structure and the chuck 400. The positioning ring 500 has a sealing surface 501 arranged forward for abutting against the wall panel.

[0026] The aforementioned process water through-plate connector for cleanrooms in biopharmaceutical production workshops, through the design of the chuck 400, connects the equipment pipelines of the cleanroom to the tubular body 100. Then, through the design of the connection structure, it connects the process pipelines in the technical channel to the tubular body 100, thereby achieving the connection of production equipment and process pipelines in the technical channel of the seed production workshop cleanroom. During installation, the positioning ring 500 allows for quick positioning and installation, and the sealing surface 501 abuts against the cleanroom wall panel, effectively sealing any cracks in the wall panel and achieving a tight seal.

[0027] Specifically, the connection structure includes a threaded section 200, which is arranged circumferentially along the tubular body 100. The threaded section 200 has a simple design and is easy to connect.

[0028] Specifically, the process water through-plate connectors used in the cleanroom of the biopharmaceutical workshop are made of 316L stainless steel.

[0029] In a preferred embodiment, the threaded section 200 is provided with sealant, and the threaded sealant is squeezed out by the engagement of the internal and external threads to enhance the sealing performance.

[0030] In this embodiment, the threaded segment 200 is arranged circumferentially around the outer periphery of the tubular body 100.

[0031] In this embodiment, the threaded section 200 may also be arranged on the inner circumference of the tubular body 100.

[0032] Specifically, the fastening structure includes a fastening washer 310 and a fastening nut 320, which are sequentially fitted onto the rear of the threaded section 200. This design is simple, allows for easy disassembly of the process water-passing plate connector by adjusting the fastening nut with a knob, and provides convenient, sealed, and durable installation.

[0033] In a preferred embodiment, the tubular body 100 has a radially outwardly expanding limiting ring 600 at its center, the limiting ring 600 having a forward-facing limiting surface; a recessed limiting ring groove 601 is provided on the limiting surface, the limiting ring groove 601 is arranged circumferentially around the limiting surface, and a limiting sealing ring is provided in the limiting ring groove 601. Thus, after connection to an external channel, the limiting sealing ring in the limiting ring groove 601 can be compressed, causing it to elastically deform, thereby enhancing the sealing performance between the process water through-plate joint and the external pipeline. Simultaneously, the design of the limiting ring 600 ensures a tight connection.

[0034] Specifically, the chuck 400 is fixedly connected to the end of the tubular body 100 by welding. A stable connection is achieved through welding.

[0035] In this embodiment, the chuck 400 has a rearwardly arranged annular surface 401, on which a downwardly recessed annular groove 402 is provided, which is arranged circumferentially around the annular surface 401. Thus, a sealing ring can be provided in the annular groove 402 to enhance the connection between the production equipment and the process water through-plate connector.

[0036] The tubular body 100 has a flow channel 101 extending through both ends, and the inner wall of the flow channel 101 is mirror-polished to a smooth finish. This facilitates material flow, prevents stagnation and the growth of microorganisms, and avoids contamination.

[0037] The outer diameter of the sealing surface 501 is the same as the outer diameter of the fastening gasket 310. In this way, the axial force applied to the fastening gasket 310 by the fastening nut 320 acts on the sealing surface 501. Since the outer diameters of the fastening gasket 310 and the sealing surface 501 are the same, the range of force application completely overlaps, which can avoid the problem of edge stress concentration or insufficient support in the central area caused by diameter difference.

[0038] The chuck 400 is conical, and the positioning ring 500 is conical; this facilitates the installation of the chuck 400. The conical positioning ring 500 has a sloped transition area, which can decompose the force into axial force and radial force, and also has good sealing performance under conditions such as thermal expansion and contraction.

[0039] A ring-shaped elastic layer 510 is provided on the contact surface, which completely covers the contact surface. The design of the elastic layer 510 can prevent the gaps on the wall surface from not being completely sealed when the wall surface is uneven.

[0040] When maintenance, repair, cleaning and other related technical work is required for facilities and equipment, the process pipe on the front end of the process water through-plate connector can be unscrewed and removed. Then, the fastening nut 320 can be loosened by turning it outward along the thread section 200. The fastening nut 320 and the fastening washer 310 can be removed. Then, the chuck 400 at the rear end of the process water through-plate connector can be released, and the sealing ring can be removed from the annular groove 402. The process water through-plate connector can then be removed for maintenance, repair and cleaning. The disassembly operation is convenient and quick.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
