Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model; obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by the person skilled in the art based on the embodiments in the utility model without creative labor belong to the protection scope of the utility model.

[0027] Please refer to Figures 1-5A quick-opening and closing soft-seal gate valve structure includes a valve body 1, a valve plate 2, and a driving component 3. The valve body 1 includes a guide cylinder 11 and a valve shell 12. A through hole is horizontally opened in the middle of the valve shell 12, and the guide cylinder 11 is horizontally connected and fixed at both ends of the through hole of the valve shell 12. The valve plate 2 is arranged inside the valve shell 12. The valve plate 2 includes an upper valve plate 21 and a lower valve plate 22. The upper valve plate 21 and the lower valve plate 22 are vertically symmetrically arranged inside the valve shell 12, and a valve stem 23 is vertically fixed on the far end face of the upper valve plate 21 and the lower valve plate 22. A slide cylinder 121 is vertically connected and fixed at both the upper and lower ends of the valve shell 12, and the valve stem 23 is vertically slidably connected through the slide cylinder 121. The driving component 3 is arranged outside the valve shell 12, and the driving component 3 is arranged outside the valve shell 12. The two ends of the moving component 3 are fixedly connected to the valve stems 23 at the upper and lower ends of the valve body 12, respectively. During use, the driving component 3 drives the upper valve plate 21 and the lower valve plate 22 on the upper and lower sides of the valve body 12 to move vertically, thereby completing the overall opening and closing of the valve body 2. Since the upper valve plate 21 and the lower valve plate 22 are made of EPDM elastic material, they are flexibly squeezed together during opening and closing, ensuring that the upper valve plate 21 and the lower valve plate 22 are closed together with each other and with the adjacent valve body 12, thus ensuring the sealing of the opening and closing. At the same time, compared with the traditional single valve plate, the upper valve plate 21 and the lower valve plate 22 are shorter in length and width, reducing the opening and closing stroke, enabling rapid opening and closing, and facilitating the convenience of subsequent opening operations.

[0028] See Figure 5 The driving component 3 includes a rotating base 31, which is horizontally fixed to the middle of the outer wall of the valve housing 12. Both ends of the rotating base 31 are vertically rotatably connected to studs 32. A rotating plate 33 is horizontally fixed to one end of the studs 32 near the rotating base 31. A screw cylinder 34 is vertically threaded onto the studs 32. A push plate 35 is horizontally fixed to one end of the screw cylinder 34 away from the rotating base 31. The other end of the push plate 35 is fixed to the top surface of the valve stem 23. During use, rotating the screw cylinder 34 on the rotating base 31 drives the screw cylinder 34 to move vertically, which in turn drives the push plate 35 to pull the valve stem 23 on the upper valve plate 21 and the lower valve plate 22 to move vertically to open and close the valve.

[0029] See Figure 4The upper valve plate 21 and the lower valve plate 22 are respectively provided with a butt block 25 and a butt groove 24 on the adjacent horizontal end faces, and the butt block 25 and the butt groove 24 of the upper valve plate 21 and the lower valve plate 22 are inserted and matched, the middle parts of the adjacent horizontal end faces of the upper valve plate 21 and the lower valve plate 22 are respectively provided with a clamping groove 26, and the inner middle part of the valve shell 12 is horizontally fixed with a clamping strip 13, and the clamping strip 13 is inserted with the clamping groove 26 on the upper valve plate 21 and the lower valve plate 22, and the upper valve plate 21 and the lower valve plate 22 are butted to ensure the sealing performance of the opening and closing of the upper valve plate 21 and the lower valve plate 22, and the inner middle part of the valve shell 12 is horizontally fixed with the clamping strip 13, and the clamping strip 13 is inserted with the clamping groove 26 on the upper valve plate 21 and the lower valve plate 22, so as to ensure the rigidity of the upper valve plate 21 and the lower valve plate 22 when closed, avoid the deviation of the opening and closing of the upper valve plate 21 and the lower valve plate 22 caused by water pressure, and cause poor sealing of the upper valve plate 21 and the lower valve plate 22.

[0030] Referring to Figure 3 The flange ring plate 111 on the guide cylinder 11 is communicated and fixed away from the valve shell 12, and the flange ring plate 111 on the guide cylinder 11 is convenient for later assembly of the communication pipeline.

[0031] In use, the upper valve plate 21 and the lower valve plate 22 on the upper side and the lower side of the valve shell 12 in the valve body 1 are vertically moved by the driving member 3, and the opening and closing of the valve body 2 is completed, and since the upper valve plate 21 and the lower valve plate 22 are made of EPDM elastic material when opening and closing, the upper valve plate 21 and the lower valve plate 22 are flexibly extruded together, so as to ensure that the upper valve plate 21 and the lower valve plate 22 are closed together with the adjacent valve shell 12, and the sealing performance of opening and closing is ensured.

[0032] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
