Abstract

The invention discloses a fast opening and closing gate valve with pendulum in the middle chamber, which comprises a gate valve body, a gate valve cover, a driving valve rod and a gate valve middle chamber. The drive valve rod runs through the gate valve cover, the middle part of the inside of the runner is provided with a movable connection sleeve, the lower end of the movable connection sleeve is evenly distributed with limited blocks, and the lower part of the gate valve cover is provided with Connecting the tooth groove, the right side of the first movable shutter is provided with a second movable shutter, and the side of the second movable shutter is provided with a flexible graphite sealing gasket. The pendulum-type fast opening and closing gate valve in the middle cavity is equipped with a first movable gate and a second movable gate for synchronous parallel swing opening and closing. The limit block of the movable connection sleeve can facilitate the flexible limit of the device and improve the practicability of the device.

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 ...
