Abstract

The invention discloses a middle cavity inner swinging type fast-starting and fast-closing gate valve. The gate valve comprises a gate valve body, a gate valve cover, a driving valve rod and a gate valve middle cavity, wherein a gate valve seat is arranged above the gate valve body, a limiting movable groove is formed in the inner side of the gate valve seat, the driving valve rod is located at the upper portion of the inner side of the gate valve cover, a movable connecting sleeve is arranged in the middle of the inner side of a rotating wheel, limiting clamping blocks are uniformly distributed at the lower end of the movable connecting sleeve, a connecting tooth groove is formed below the gate valve cover, a second movable gate is arranged on the right side of a first movable gate, and aflexible graphite sealing gasket is arranged on the side face of the second movable gate. According to the middle cavity inner swinging type fast-starting and fast-closing gate valve, the first movable gate and the second movable gate which perform synchronous parallel swing opening and closing are arranged, the device can be quickly opened and closed under the synchronous transmission of the connecting tooth groove, and meanwhile, the limiting clamping blocks of the movable connecting sleeve can be used for conveniently and flexibly limiting the device, so that the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field related to valves, in particular to a fast opening and closing gate valve with a swing type in a middle cavity. Background technique [0002] The gate valve is usually opened and closed through the gate in the direction perpendicular to the fluid movement direction to control the full opening and closing of the valve. It is widely used in water conservancy and oil and gas pipelines and other fields, and it is convenient and flexible to control the opening and closing of the connecting pipeline. Now Some gate valves usually use the hand wheel outside the valve body to drive the screw to lift or lower the gate to open or close the pipeline. However, when the hand wheel is continuously turned, the labor intensity of the staff is very high. , It takes a long time, reduces the work efficiency, and is not convenient for the rapid opening and closing of the valve gate. [0003] For example, a ball screw slab gate ...
