Abstract

The invention relates to the technical field of flow regulation, and discloses a flow regulation device utilizing the flow coefficient of a flow regulator. The flow regulation device comprises a box body, a hollow column is fixedly arranged in the box body through a connecting rod, a first rotating rod is rotatably arranged in the hollow column through two first bearings, and an impeller is fixedly arranged on the rod wall of the first rotating rod; through holes are formed in the upper surface and the lower surface of the hollow column, a first water pipe and a second water pipe are fixedly connected to the upper surface and the lower surface of the hollow column in a sleeved manner correspondingly, a flow regulator is fixedly arranged on the pipe wall of the first water pipe, and the right end of the first rotating rod penetrates out of the hollow column and is fixedly connected with a first bevel gear; and the first bevel gear is fixedly connected with a driving mechanism and an adjusting mechanism through a transmission mechanism. According to the flow regulation device, the flow can be automatically adjusted, and the irrigation effect is improved.

Description

technical field [0001] The invention relates to the technical field of flow regulation, in particular to a flow regulating device utilizing the flow coefficient of a flow regulator. Background technique [0002] The flow regulator has an annular throttle body made of elastic material, which delimits between itself and the regulating star wheel a control gap that varies under the pressure of the fluid flowing through, wherein the regulating star wheel held on the lead screw is in its The outer circumference is provided with a longitudinally varying adjustment profile and is guided displaceably in the longitudinal direction, so that the rotational movement of the spindle can be converted into a longitudinal movement of the adjustment star wheel so that by adjusting the relative position of the star wheel and the throttle body Change to change the control gap. [0003] Wherein the patent No. CN108934990A discloses a garden lawn irrigation device, including a base, the upper su...
