Abstract

The invention discloses a stepping linear driver driving a ratchet wheel to rotate through hydraulic pressure. The stepping linear driver is characterized in that a first driving cylinder and a second driving cylinder are arranged on a driver body; the first driving cylinder and the second driving cylinder are provided with reset springs for resetting; piston rods of the first driving cylinder and the second driving cylinder are arranged matched with pawls; the pawls rotate around rotating pins; compression springs are arranged on the pawls; the compression springs have spring acting force on the pawls, so that pawl teeth of the pawls are matched with the ratchet wheel, and the ratchet wheel is driven to anticlockwise or clockwise rotate; the ratchet wheel is arranged on a power shaft; a driving gear is arranged on the power shaft as well; the driving gear is meshed with a matched driven gear; and the driven gear is driven to rotate to output driving torque. According to the obtained driver, through the driving cylinders and the stepping rotation of the ratchet wheel, the rotation amount can be accurately controlled, the control accuracy is greatly improved, and the pressure of a fluid passing through a valve is guaranteed to be constant in a set range; and the ratchet wheel is driven to anticlockwise or clockwise rotate through the two driving cylinders on the left and right, the rotation is flexible and reliable, and the reliability of a throttle valve is greatly improved.

Description

technical field [0001] The invention relates to a throttle valve driver for controlling pipeline flow (pressure), in particular to a driver for an underwater recoverable throttle valve. The throttle valve is mainly used to adjust or control the flow (pressure) of liquid in the pipeline. Background technique [0002] In offshore oil production, the Christmas trees, oil pipelines, oil pipelines, etc. are all buried (laid) underwater. Due to the different formation parameters of each well, the pressure of the liquid (fluid) entering the pipeline from the Christmas tree is also quite different. , in order to bring the fluid of each well into the same manifold, it is necessary to adjust the pressure of the liquid (fluid) entering each sub-pipeline, so that the fluid pressure of each sub-pipeline entering the main pipeline is basically the same, ensuring the fluid pressure of the main pipeline It is basically constant within the set range to prevent the pressure from fluctuating o...
