Chain operated gate valve is a valve that controls the opening and closing of the gate through a chain transmission mechanism. Its main components include a sprocket, a chain and a handwheel (or an electric drive device). When the handwheel is driven manually or electrically, the sprocket rotates, and the gate is driven by the chain to perform a linear lifting and lowering motion, thereby realizing the opening and closing of the valve.
Applications
The Chain operated gate valve is usually used for remote operation in high or inaccessible locations. This valve design is suitable for application scenarios that require control at a long distance or inconvenient to operate directly. For example, in industrial pipeline systems, chain gate valves can be used to cut off the flow of media, especially in large-diameter or high-pressure conditions. The use of chain transmission can amplify the operating force and make the operation of the valve more labor-saving.
Remote operation: Due to the characteristics of chain transmission, the chain gate valve is particularly suitable for remote operation, and the valve can be opened and closed at high or inaccessible locations.
Space saving: The chain gate valve has an ultra-short structural length, occupies a small effective space, can effectively support the strength of the pipeline, and reduce the possibility of pipeline vibration.
Corrosion resistance: The gate is usually made of austenitic stainless steel and other materials, which improves the corrosion resistance and is suitable for a variety of working environments.
