Automatic switch capable of controlling opening/closing of pipeline pump according to pressure and flow of fluid

Abstract

The invention relates to a control switch for a pipeline pump, in particular to an automatic switch capable of controlling the opening / closing of the pipeline pump according to the pressure and flow of a fluid. The invention aims to provide an automatic control switch capable of automatically controlling the opening / closing of the pipeline pump according to water pressure and flow. The automatic switch capable of controlling the opening / closing of the pipeline pump according to the pressure and flow of the fluid comprises a cavity-shaped base, wherein an opening is formed at the upper end of the cavity-shaped base; a water inlet interface with a thread is arranged at the left end of the cavity-shaped base; a water outlet interface with a thread is arranged at the right end of the cavity-shaped base; the outer wall at the upper end of the cavity-shaped base is provided with a base ear plate; a supporting plate with holes is horizontally arranged on the inner wall of the left part of the opening at the upper end of the cavity-shaped base; and the surface of the supporting plate with the holes has small holes. The invention aims to provide the automatic control switch capable of automatically controlling the opening / closing of the pipeline pump according to water pressure and flow, and is applicable to the automatic control of pipeline pumps in water supply systems.

Description

technical field [0001] The invention relates to a pipeline pump control valve, in particular to an automatic switch capable of controlling the opening and closing of a pipeline pump according to fluid pressure and flow. Background technique [0002] During the operation of the tap water system, it is necessary to control the opening and closing of the pipeline pump according to the water pressure and flow rate of the monitoring point in the system, so as to ensure the pressure in the water supply pipeline after the monitoring point. Judging from the current technical situation, the opening and closing of the pipeline pump is usually completed with a pressure control switch or a flow control switch, or a switch group composed of a pressure control switch and a flow control switch. Most of these switches use mechanical control circuits, which not only have low control accuracy but also poor work reliability, which usually easily leads to failure of the control device and frequ...
