Foldable valve handle system capable of adjusting torque

Abstract

The invention discloses a foldable valve handle system capable of adjusting torque. The foldable valve handle system comprises a wheel disc and wheel disc handles, wherein three grooves are formed in the outer side of the wheel disc in an annular array; the wheel disc handles are arranged in the grooves; a square hole is formed in the middle of the wheel disc; a valve stem clamping sleeve is mounted in the square hole; strip-shaped grooves are formed in the wheel disc handles; folding handles are arranged in the strip-shaped grooves; and the folding handles are hinged to the strip-shaped grooves. The folding handles are arranged on the wheel disc handles, and the lengths of the wheel disc handles can be adjusted, so that the torque can be reduced. A universal valve stem clamping sleeve mounting hole is formed in the wheel disc, and the valve stem clamping sleeve can be replaced according to different valve stem shapes and sizes, so that resources can be saved. The taper is designed on the valve stem clamping sleeve mounting hole in the wheel disc, clamping is facilitated and dropping is prevented. The grooves are formed in the wheel disc, the wheel disc handles can be folded, so that the foldable valve handle system is adaptive to operation in a narrow space, and storage is facilitated. The three grooves are formed in the wheel disc, and the wheel disc handle(s) can be arranged in one groove, two grooves or three grooves, so that the fitness to operation space can be further improved.

Description

technical field [0001] The invention relates to the field of a valve handwheel device, in particular to a foldable and moment-adjustable valve handwheel system. Background technique [0002] Valves are the control components in the fluid delivery system. The valves used in the fluid control system range from the simplest globe valve to various valves used in extremely complex automatic control systems. There are quite a variety of valves and specifications. Valves can be used to control air, The flow of various types of fluids such as water, steam, various corrosive media, mud, oil, liquid metal and radioactive media; valves that are manually opened and closed are generally equipped with handwheels, which are circular in structure , the principle is to use the radius of the handwheel as the force arm to enhance the rotational torque. Therefore, under the same torque, the larger the radius of the handwheel, the greater the torque. However, the radius of the existing handwheel...
