Problems solved by technology

[0004] The purpose of the present invention is to provide an electric gate valve to solve the problem in the background technology mentioned above. Since the application scene of the electric gate valve requires higher movement precision of the opening and closing valve plate, in the existing gate valve, A corresponding chute / slide structure will be set in the valve body to ensure the stability of the movement of the opening and closing valve plate. However, when the valve body is opened to convey materials, the falling of the material is continuous. During the process, the material is easy to move into the chute following the movement of the opening and closing valve plate, and the long-term use will easily cause the position shift of the opening and closing valve plate due to the blockage of the material and the problem of stroke jam

Embodiment 1

[0037] like Figure 1-6 The shown plug-in valve includes a valve body shell 1 and an opening and closing valve plate 5. The opening and closing valve plate 5 is slidably connected in the chute 8, and the center of the valve body shell 1 is also provided with a vertically penetrating valve body material hole 2. And the upper and lower sides of the valve body material hole 2 are respectively provided with a flange interface 3 installed on the valve body shell 1, the flange interface 3 is connected with the material pipe 4, and the chute 8 is provided on the valve body shell around the valve body material hole 2. 1, and the surface area of ​​the valve body material hole 2 is smaller than the surface area of ​​the opening and closing valve plate 5, the opening and closing valve plate 5 is connected to the driver 7 through the connecting frame 6, and the driver 7 is fixed at the end of the valve body shell 1, and also Including an additional ring 9, the additional ring 9 is arrange...

Embodiment 2

[0041] Different from the first example, as Figure 7-9 As shown, the movable sealing device in this embodiment is an elastic sheet 17 and an air cavity 18. The air cavity 18 is opened inside the valve body casing 1, and the air cavity 18 is connected with the driving device. The elastic sheet 17 covers the air cavity 18. At the opening at the bottom end, the driving device inputs air toward the inside of the air cavity 18, and the air pressure makes the elastic sheet 17 elastically deform, thereby opening and closing the chute 8, the opening and closing valve plate 5 is closed, and the elastic sheet 17 expands to prevent the material from being pushed into the slide. In the groove 8, the opening and closing valve plate 5 is opened, and the elastic sheet 17 is retracted, so as to avoid excessive frictional contact between the opening and closing valve plate 5 and the seal.

[0042] like Figure 8-9 As shown, the driving device includes an air pipe 19 and an air supply device ...

Abstract

The electric gate valve comprises a valve body shell and an opening and closing valve plate, the opening and closing valve plate is connected into a sliding groove in a sliding mode, a vertically-penetrating valve body material hole is further formed in the center of the valve body shell, and flange connectors installed on the valve body shell are arranged on the upper side and the lower side of the valve body material hole correspondingly; the additional ring is fixedly connected with the bottom wall of the valve body shell through a connecting block, leakage holes are further formed in the connecting block, the additional ring and the valve body shell which are distributed at equal angles, the leakage holes are used for discharging materials pushed into the sliding groove when the opening and closing valve plate is closed, and the finger ring is located on the finger ring fixing base. According to the electric gate valve, the corresponding movable sealing structure is used at the sliding groove around the material hole of the valve body, the position of the sealing structure can be automatically adjusted according to movement of the opening and closing valve plate, and it is guaranteed that excessive friction between the opening and closing valve plate and the sealing structure cannot be caused when the opening and closing valve plate is opened; when the opening and closing valve plate is closed, adaptive sealing can be automatically conducted on the sliding groove, materials are effectively prevented from entering the sliding groove along with the opening and closing valve plate, and repeated disassembly, assembly and cleaning are not needed.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to an electric plug-in valve. Background technique [0002] The plug-in valve uses the opening and closing valve plate as the opening and closing part. Under the drive of the driver, it moves correspondingly in the valve body and controls the valve hole on and off. According to the different operation methods, it can generally be divided into manual plug-in valve and Electric / hydraulic flapper valves, of which the latter is more widely used, and are used more frequently in the material conveying on-off control system, but the existing similar electric flapper valves still have the following problems in actual use: [0003] Since the application scenario of the electric plug-in valve has higher requirements on the movement accuracy of the opening and closing valve plate, in the existing plug-in valve, a corresponding chute / slideway structure will be set in the valve body to e...
