Movable thread-off proof anti-skid F-shaped valve key

Abstract

The invention relates to a movable thread-off proof anti-skid F-shaped valve key which comprises a handle (1), a first driving end (2) and a second driving end (3). The first driving end (2) is connected to the end of the handle (1), the second driving end (3) is connected to the side wall of the handle (1), an F shape is formed after the handle (1) is connected with the first driving end (2) andthe second driving end (3), a driving end thread part (32) is arranged on the second driving end (3), a nut (4) is connected to the driving end thread part (32), a rod (5) is welded and connected to the outer wall of the nut (4), and the length of the rod (5) is smaller than the distance between the first driving end (2) and the second driving end (3). The valve key can be clamped and connected toa valve conveniently, and the phenomenon that the F-shaped key falls down when a user exerts force is avoided.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to an F-type wrench. Background technique [0002] F-type wrench is a very common tool in the field of valve switch technology. It is a special wrench that increases the torque for the convenience of opening the valve. Its shape is very similar to the English letter F, and it is widely used in various handwheel types. Valve switch. [0003] When using the F-type wrench, you should pay attention to the following points: (1) First, it should be firmly locked with the door wheel to prevent disengagement; (2) The operator should separate his feet and stand firmly on the soles of his feet, and support his legs reasonably to prevent falling ;(3) The operator should hold the handle tightly with both hands, and use reasonable and even force to avoid violent force or violence; (4) The handle of the valve wrench should be at the same level as the door wheel, so that the force of the valve w...

Problems solved by technology

However, in actual production, it is often encountered that the existing F wrench still cannot solve the problem perfectly

[0005] When operating the handwheel on the manual stop valve at the production site, if there is one of the conditions such as the valve stem lacks oil and rusts, the valve handwheel has no spokes, the pressure difference between the front and rear of the valve is too large, and the valve handwheel is too large, etc., it will appear. When using a wrench to operate the valve with great force, the valve wrench slips away from the hand wheel, and it is not uncommon for the operator to be injured due to inertia
