Description

Technical Field

[0001] This utility model relates to the technical field of sanitary dual-guide single-seat straight-through control valves, specifically a modular sanitary dual-guide single-seat straight-through control valve. Background Technology

[0002] In industries with stringent hygiene requirements, such as healthcare, food and beverage, and pharmaceuticals, the performance of fluid control valves directly impacts product quality and production safety. Traditional single-seat valves, products of the 1980s and 90s, have an outdated structure comprised of valve bodies, valve cores, and other components. When used to transport high-temperature, highly corrosive fluids, not only is the valve cavity susceptible to corrosion, leading to increased leakage, but it also creates unsanitary areas that easily breed contaminants, significantly shortening the valve's lifespan and failing to meet the demands of modern high-cleanliness production.

[0003] This utility model is a modular sanitary double-guided single-seat straight-through control valve, widely applicable in medical, food and beverage, and pharmaceutical industries for applications requiring high hygiene standards. It can be used with various clean and corrosive fluids. The valve features a precise design, meeting the requirements for low leakage, corrosion resistance, and vibration resistance in fluid control. Compared to traditional valves, sanitary valves place greater emphasis on hygiene and safety in material selection, surface treatment, and sealing structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular sanitary dual-guide single-seat straight-through control valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular sanitary dual-guide single-seat straight-through control valve, comprising: two sets of valve bodies with opposite openings and arranged vertically, wherein the lower valve body is used for medium inlet and the upper valve body is used for medium outlet, and the channel is S-shaped streamlined.

[0006] The lower valve body of the two sets of valve bodies is provided with a bottom cover, and a valve seat is fixedly arranged between the two sets of valve bodies. The upper valve body is provided with a valve cover, and the lower valve body is provided with a bottom cover. Each module is fixed in pairs by external clamps.

[0007] The valve cover is provided with a bushing inside, and the valve seat, valve cover, and bushing are provided with a valve core. One end of the valve core is located on the outside of the valve cover, and the valve core passes through two sets of valve bodies.

[0008] The valve core is a four-claw valve core, used to guide fluid and reduce vibration.

[0010] O-rings are fitted at the connection between the valve seat and the upper and lower valve bodies.

[0011] As a further description of the above technical solution:

[0012] O-rings are provided at the connection between the bottom cover and the lower valve body, and at the connection between the valve cover and the upper valve body.

[0013] As a further description of the above technical solution:

[0014] Two sets of star-shaped sealing rings are fitted between the valve core and the valve cover.

[0015] As a further description of the above technical solution:

[0016] A dustproof ring is fitted on the top of the valve cover to prevent external contamination of the valve body.

[0017] As a further description of the above technical solution:

[0018] The valve core moves up and down inside the valve body via a bushing to control the fluid flow rate.

[0019] This utility model has the following beneficial effects:

The lower valve body 2 is used for medium inlet, and the upper valve body 2 is used for medium outlet. The channel is S-shaped streamlined.

[0030] The lower valve body of the two sets of valve bodies is provided with a bottom cover 1, and a valve seat 3 is fixedly arranged between the two sets of valve bodies 2. The upper valve body is provided with a valve cover 7, and the lower valve body is provided with a bottom cover 1. Each module is fixed in pairs by external clamps.

[0031] The valve cover 7 is provided with a bushing 8 inside, and the valve seat 3, valve cover 7, and bushing 8 are provided with valve core 5. One end of the valve core 5 is located on the outside of the valve cover 7, and the valve core 5 passes through two sets of valve bodies 2.

[0032] The valve core 5 is a four-claw valve core, used to guide fluid and reduce vibration.

[0033] In this embodiment, the medium enters from the lower valve body, flows through the valve seat 3 along the S-shaped streamlined channel, and then flows out from the upper valve body; each module is quickly connected and fixed by clamps, which facilitates disassembly and assembly, ensuring stable delivery of the medium, and the modular design facilitates maintenance.

[0034] In this embodiment, the valve core 5 moves up and down within the bushing 8 to change the fluid flow area, thereby controlling the fluid flow rate; the four-claw structure guides the fluid, disperses the fluid impact force, and reduces vibration.

[0035] Specifically, O-rings 4 are fitted at the connection between the valve seat 3 and the upper and lower valve bodies.

[0036] As a preferred implementation, when the clamp is tightened, the O-ring is compressed to fill the gap, preventing the medium from leaking at the connection between the valve seat and the valve body.

[0037] Specifically, O-rings 4 are provided at the connection between the bottom cover 1 and the lower valve body, and at the connection between the valve cover 7 and the upper valve body.

[0038] It should be noted that the O-ring 4 is used to prevent the medium from leaking from the connection between the valve body and the bottom cover and valve cover.

[0039] Specifically, two sets of star-shaped sealing rings 6 are fitted between the valve core 5 and the valve cover 7.

[0040] As a preferred embodiment, the star-shaped sealing ring 6 is star-shaped and can be made of fluororubber to prevent the medium from leaking along the gap between the valve core 5 and the valve cover 7.

[0041] Specifically, a dustproof ring 9 is fitted on the top of the valve cover 7 to prevent external contamination of the valve body.

[0042] It should be noted that the dustproof ring 9 is used to block external dust and impurities from entering the valve body and prevent external contaminants from entering the valve body.

[0043] Specifically, the valve core 5 moves up and down inside the valve body 2 via the bushing 8 to control the fluid flow rate.

[0044] In this embodiment, the externally driven valve core 5 moves inside the bushing 8, causing the four-jaw valve core to move and change the flow area, thereby changing the fluid flow rate.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
