Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of ship tools, concretely relates to a marine valve fork. BACKGROUND

[0002] During the installation, inspection, debugging and use of the pipeline of the ship, the opening and closing of the valve of the pipeline are frequently involved. At present, the conventional F-shaped valve fork is usually used to open and close the valve. However, the nameplate on the valve hand wheel extends outward from the hub of the valve hand wheel. The F-shaped valve fork is likely to slide along the spoke to the edge of the nameplate of the valve hand wheel, which causes the edge of the nameplate to be easily folded and damaged. In severe cases, the nameplate is damaged to such an extent that it cannot be repaired and used, which results in the inability to identify the information of the valve, and finally the nameplate has to be replaced, which increases the additional cost. Moreover, some valves on the pipeline of the ship are arranged in a narrow space, and the length of the valve rod of the existing valve fork is fixed. The fixed design cannot adapt to the opening and closing of the valve in the narrow space. Therefore, in order to avoid the shortcomings in the prior art, it is necessary to improve the prior art.
