Description

Technical Field

[0001] The utility model belongs to the technical field of ship valve components, and more specifically, relates to a valve stem control device for ship valve components. Background Art

[0002] The ship's sea valve is a valve used to regulate the flow of seawater inside and outside the ship. During the voyage of the ship, it is often necessary to adjust the valve opening of the sea valve to control the flow of seawater. The sea valve also needs to be closed when the seawater pipeline on the ship needs maintenance. However, the sea valve is usually installed at the bottom or side of the hull. If the operating handwheel is under the flower plate, it will bring great difficulty to the operation, and there will be great safety hazards when the ship needs to urgently close the sea valve.

[0003] At present, the technical solution to solve the above problem on board is: directly weld an extension rod on the valve stem of the sea valve, and then add a control handwheel on the upper end of the extension rod. This extension method needs to be welded on the original sea valve handwheel, which will damage the original sea valve structure, and the welding cannot guarantee long-term use, resulting in poor reliability of the entire structure and a short service life.

[0004] In the prior art, there is a technology named "A Valve Opening and Closing Device for Ship Pipeline System" and the publication number is "CN114860026A". This technology provides a valve opening and closing device for ship pipeline system, including a valve clamping part, a rotating motor and a connecting rod. The valve clamping part includes a clamping member and a connecting seat, and the valve clamping part is used to be fixedly connected to the valve disc of the valve component. The output shaft of the rotating motor is fixedly connected to the connecting seat, and the rotating motor is used to control the forward or reverse rotation of the valve clamping part. The length of the connecting rod can be adjusted telescopically, and the connecting rod is used to extend the valve clamping part to the valve disc of the valve component. When the valve disc of the valve component is arranged in a narrow space, too high a height or too deep a depth, it is inconvenient for the staff to open and close the valve disc of the valve component. The valve clamping part is extended to the valve disc of the valve component at different depths or heights by the connecting rod with adjustable length. The valve disc of the valve component is fixed by the clamping area, and the rotation of the valve clamping part is controlled by the rotating motor, so as to control the opening and closing of the valve disc of the valve component, thereby avoiding the situation that the pipeline fails due to untimely opening and closing. This technology does not involve the technical problems and technical solutions of this application. Utility Model Content
