Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to an anti-freezing and anti-theft clamp gate valve. Background Art

[0002] Gate valves are a common type of valve, primarily used to interrupt or connect the flow of media in pipelines. They control the valve's opening by raising or lowering the gate disc, thereby enabling or disabling fluid flow or regulating flow. Gate valves are widely used in numerous fields, including industrial production, municipal water supply, petrochemicals, and electric power. They have a long history and are an indispensable component of pipeline systems.

[0003] Chinese patent CN214578970U discloses an antifreeze and anti-theft clamp gate valve, comprising a ring plate, a valve body being fixedly connected to the inner wall of the ring plate, a protective unit being provided above the ring plate, the protective unit comprising an annular groove, a rubber pad, a cover, an air extraction nozzle, a transverse plate, a conical cylinder, a conical plug, a transverse rod, a transverse cylinder, a lock body, a first pin, a second pin, a first compression spring, and a bolt, wherein the annular groove is provided around the upper surface of the ring plate. The antifreeze and anti-theft clamp gate valve, through the cooperation between the ring plate, the valve body, and the protective unit, presses the conical plug against the conical cylinder, thereby pressing the cover against the rubber pad, i.e., the cover is not easily separated from the ring plate, thereby protecting the knob above the valve body and improving the anti-theft performance of the valve body. At the same time, the interior of the cover is in a relatively vacuum state, which makes it difficult for temperature to be transmitted, thereby facilitating temperature resistance and antifreeze at the knob above the valve body, thereby enhancing the practical performance of the valve body.

[0004] The above technical solution uses vacuum to achieve anti-theft and anti-freeze effects. During use, it needs external vacuum equipment and power support, has high requirements for logistics support, and still cannot achieve anti-freeze effects in low temperature environments for a long time.
