Description

Technical Field

[0001] The utility model relates to the technical field of crank handles, in particular to a portable movable crank handle for a low-torque valve hand wheel. Background Art

[0002] In our daily work, we often encounter various valves. When we encounter a valve handwheel with a higher torque (that is, a valve that is physically felt or verbally described as heavier), we will use a tool called a valve hook to increase the lever arm to make the valve easier to operate.

[0003] But at the same time, we also found that when it comes to valve handwheels that require switching at lower torques (i.e. valves that are physically felt or verbally described as lighter), sometimes we encounter such valves that need to be switched on and off for hundreds or even thousands of turns. Because the handwheels are large and require more turns, it is not convenient for personnel to operate on-site.

[0004] In the prior art, the China Patent Network Announcement No.: CN208153833U discloses a rapid opening and closing device for a valve, including a crank, a limit plate, a support beam, and a limit ring. The support beam is fixedly connected to the limit ring, one end of the support beam is fixedly connected to each other, and the other end is evenly distributed along the limit ring; one or more limit plates are fixed on the support beam, the limit plates are in an inverted T-shaped structure, and the limit plates are evenly distributed around the circumference; the crank is fixed to the outer end of the support beam. The advantages are: the overall structure is simple, safe and reliable, easy to use, and the valve opening and closing saves time and effort, and reduces labor intensity. The support beam is set similar to the handwheel structure of the valve itself, which is convenient for clamping the limit plate on the handwheel, and the force of opening and closing the valve is uniform and stable, and the operation is safe and reliable; a crank is added to the end of the support beam to realize continuous opening and closing of the valve, improve the working efficiency of opening and closing the valve, and reduce the labor intensity of workers when opening and closing the valve; a sleeve is movably connected to the crank to prevent hand grinding when opening and closing the valve.

[0005] Although the device can improve the efficiency of opening and closing the valve during the actual process of rotating the valve handwheel, the overall size of the device is large and inconvenient to carry, and the stability is poor during the process of rotating the handwheel, which brings inconvenience to the operator.

[0006] In view of this, the utility model proposes a portable movable crank handle of a low-torque valve handwheel. Utility Model Content
