Technical Field

[0001] The utility model belongs to the technical field of manual flat valves, and in particular relates to a manual flat valve which can be conveniently connected to pipelines. Background Art

[0002] The flat gate valve is a sliding valve with parallel gates as the closing part. The closing part can be a single gate or a double gate with a propping mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or floating valve seat. If it is a double-disc flat gate valve, the propping mechanism between the two gates can supplement this pressing force. Flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to the driving mode. According to the purpose and application occasion, they can be divided into flat gate valves with diversion holes, flat gate valves without diversion holes, oilfield flat gate valves, pipeline flat gate valves and gas flat gate valves.

Once the pin and the interlocking part are loose, it will affect the connectivity of the two pipes.

[0005] Therefore, it is necessary to provide a new manual flat valve that can be convenient for pipeline connection to solve the above technical problems. Utility Model Content
