Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to an automatic opening and closing gate valve. Background Art

[0002] The flat gate valve is one of the commonly used shut-off valves, which mainly connects or disconnects the medium in the pipeline through a parallel gate plate. According to the structure and movement of its valve stem, it can be divided into rising stem type and concealed stem type flat gate valve. A gate valve is often installed at the bottom of the dry-mix mortar storage tank to connect the feeder and the mortar tank.

[0003] The existing plate gate valve has the following defects: it is too laborious to operate. In order to rotate the hand wheel, at least two or more male employees must work together. Moreover, due to the limited strength of the operating team, it is never possible to complete each opening and closing operation of the gate in one go. There must always be 4 to 5 short breaks during the operation to restore physical strength. Therefore, this type of gate valve is too laborious to operate. Utility Model Content

[0007] It can make the gate valve open and close automatically, so as to ensure that the opening and closing of the valve plate does not require a lot of physical strength, and ensure that the valve plate is stable enough during the movement process. The motor shaft drives a screw rod to rotate synchronously, and this screw rod will drive a sprocket connected to it to rotate synchronously. With the cooperation of the chain, this sprocket can drive another sprocket to rotate synchronously, and then the other screw rod will also be driven by the other sprocket to rotate. With the cooperation of the two screw rods, the lower drive bar can be driven to move upward, and then the valve plate will also be driven by the drive bar to move synchronously, and the gate valve will automatically open.

[0008] As a further preferred embodiment of the present technical solution, two limit rings are fixedly connected to the inner walls on both sides of the valve body, the two limit rings are respectively located at two ends of the valve body, and the same valve plate is slidably inserted between the two limit rings.
