Description

Technical Field

[0001] This invention relates to the field of blind valve technology, specifically a sector-shaped blind valve. Background Technology

[0002] A blind valve is a gate valve that shuts off gaseous media manually, electrically, or pneumatically / hydraulically. It includes a valve seat, a valve plate hinged to the valve seat at one end, and an electric actuator hinged to the valve seat at the other end. The other end of the electric actuator is hinged to the valve plate, and the valve plate rotates by extending or retracting the electric actuator. The valve seat has two hinged seats, both fixed to the valve seat by multiple bolts. Blind valves are generally classified as electric blind valves, hydraulic blind valves, pneumatic blind valves, closed-type gate valves, and electric open-type blind valves. A blind valve has three actuation devices: two manual clamping or releasing devices and one electric device to open or close the gate. To open or close the gate, the two manual devices are first released, and then the electric device is activated. After the gate is opened or closed, the two manual devices are clamped back in, allowing the pipeline to operate.

[0003] Existing sector blind valves often suffer from problems such as unstable installation due to difficulty in securing them during installation, and time-consuming and labor-intensive operation when using manual valves.
