Adjustable labor-saving valve opening and closing device

Abstract

The invention provides an adjustable labor-saving valve opening and closing device. The adjustable labor-saving valve opening and closing device comprises a machine body, a transmission mechanism, a grip component and an adjustable chuck. The two ends of the machine body are hinged to hinge supporting rods and connected with the pipeline through the hinge supporting rods. A mounting bracket is arranged on one side of the machine main body; the transmission mechanism comprises a driving shaft, a transmission assembly and a grip fastening wheel, wherein the transmission assembly and the grip fastening wheel are arranged on the driving shaft. The driving shaft is rotationally arranged on the mounting support. The grip part comprises a grip main rod and a sliding adjusting assembly; the sliding adjusting assembly is arranged on the grip fastening wheel in a sleeving mode and connected with the driving shaft in a sliding mode. One end of the adjustable chuck penetrates through the machine body and is connected with the transmission assembly. According to the device, the handle part is rotated, the transmission mechanism is used for driving the adjustable chuck to rotate so as to achieve rotation of the valve hand wheel, operation is more labor-saving, the adjustable chuck can be used for adjusting valve hand wheels of different sizes, the valve hand wheel and the adjustable chuck are fixed, and the slipping problem generated by an F-shaped wrench is avoided.

Description

technical field [0001] The invention relates to the field of valve switch equipment, in particular to an adjustable and labor-saving switch valve device. Background technique [0002] Valve is a kind of equipment widely used in chemical production, which is used to control fluid flow. On-site operators need to frequently switch and adjust some manual valves. At present, the auxiliary device used for valve operation is mainly F-type wrench, but due to the limitation of valve installation position and height, the valve switch operation has problems such as small operating space, time-consuming and labor-intensive operation, and certain safety risks in operation. In addition, the F-type wrench is cumbersome to operate, and the clamping position needs to be changed frequently, and the valve is easy to slip when operating, and the F-type wrench concentrates the force on one point of the valve handwheel, and the switch operation will cause great damage to the valve handwheel.

Problems solved by technology

At present, the auxiliary device used for valve operation is mainly F-type wrench, but due to the limitation of valve installation position and height, the valve switch operation has problems such as small operating space, time-consuming and labor-intensive operation, and certain safety risks in operation.

In addition, the F-type wrench is cumbersome to operate, and the clamping position needs to be changed frequently, and the valve is easy to slip off when operating, and the F-type wrench concentrates the force on one point of the valve handwheel, and the switch operation will cause great damage to the valve handwheel

For horizontally installed valves, the switch valve can only be operated in the horizontal direction, which brings inconvenience to the operation

[0003] In order to solve the above problems, the traditional method is to use electric valves instead of manual valves, and use electric motors to drive the valves to realize the switching operation of the valves and achieve the purpose of saving time and labor for personnel. However, the structure of electric valves is complex, prone to failure, high cost, and maintenance is relatively expensive. difficulty
