Problems solved by technology

Due to the large torque required for the opening and closing of large pipeline valves, the motor needs to consume a lot of power to drive the opening and closing of large pipeline valves, and the motor is in a high load state when it is in use, which wears out quickly and has a short service life. Driven by a torque motor, the cost of use is too high

Abstract

The invention discloses a hydraulic gear and rack oil cylinder for pipeline valve opening and closing. The hydraulic gear and rack oil cylinder comprises a box, a rack A, a rack B and a pipeline valve with a rotation switch. A hydraulic oil cylinder A and a hydraulic oil cylinder B are fixedly arranged on one side of the box in a horizontal parallel manner. A hydraulic oil cylinder C is fixedly arranged on the side, opposite to the hydraulic oil cylinder A, of the box, and a hydraulic oil cylinder D is fixedly arranged on the side, opposite to the hydraulic oil cylinder B, of the box. The rack A horizontally penetrates the box, and the two ends of the rack A are fixedly connected with a piston of the hydraulic oil cylinder A and a piston of the hydraulic oil cylinder C correspondingly. The rack B horizontally penetrates the box, and the two ends of the rack B are fixedly connected with a piston of the hydraulic oil cylinder B and a piston of the hydraulic oil cylinder D correspondingly. A gear located between the rack A and the rack B is vertically arranged in the box and engaged with the rack A and the rack B. The lower end of the gear is fixedly connected with the rotation switch of the pipeline valve. The hydraulic gear and rack oil cylinder has the beneficial effects that the structure is simple, dual twisting force is provided, energy consumption is low, and the using cost is low.

Description

technical field [0001] The invention relates to an opening and closing control device for a large pipeline valve, in particular to a hydraulic rack and pinion oil cylinder for opening and closing the pipeline valve. Background technique [0002] The opening and closing control of valves in existing large-scale pipelines (such as natural gas transmission pipelines) is usually driven by motor rotation. Due to the large torque required for the opening and closing of large pipeline valves, the motor needs to consume a lot of power to drive the opening and closing of large pipeline valves, and the motor is in a high load state when it is in use, which wears out quickly and has a short service life. Driven by a torque motor, the use cost is too high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic rack and pinion oil cylinder for opening and closing pipeline valves, which has a simple structure, provides d...
