Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment equipment technical field, concretely relates to a valve hand wheel clamping device. BACKGROUND

[0002] Various valves are installed in various water supply pipelines, and these valves need to be closed or opened at any time in case of emergency.

[0003] In the prior art, the valve is opened or closed by manual rotation of the hand wheel by an operator. The operator may need to constantly try different types and specifications of force tools, such as force rods of different lengths, crowbars of various shapes, etc., to open or close the valve. This results in the inability to quickly open or close the valve, frequent tool replacement, which not only wastes time but also increases the complexity of operation, and reduces efficiency. When the valve hand wheel is difficult to rotate due to various reasons, the operator often needs to use a force rod or other tool to try to rotate the hand wheel with great force. In the limited and complex space underground, such high-intensity operation puts the operator's body in an extremely tense state, and it is easy to lose balance due to excessive force. Moreover, there may be no place for the operator to stand on the site, and the operation space is limited. Once the operator falls down, he or she may collide with various sharp objects and equipment components underground, resulting in physical injuries such as fractures, cuts, and bruises. Moreover, if the head is hit when falling down, it may cause brain damage, with unpredictable consequences. The operator may need to spend dozens of minutes or even hours to try to open or close the valve, which affects the overall progress due to the long operation time.

[0004] Therefore, the prior art still needs to be improved and developed. CONTENT OF THE UTILITY MODEL
