Abstract

The invention relates to a pipeline pump control valve, in particular to an automatic energy-saving flow and pressure double-controlled switch for controlling a pipeline pump to start and stop, which is used for solving the problem that no automatic control switch for automatically controlling the pipeline pump to start and stop according to the water pressure and the flow exists at present. The automatic energy-saving flow and pressure double-controlled switch for controlling the pipeline pump to start and stop comprises a cavity-shaped switch base, wherein the left end of the cavity-shaped switch base is provided with a water inlet interface with screw threads; the right end of the cavity-shaped switch base is provided with a water outlet interface with screw threads; and the side surface at the left part of the cavity-shaped switch base is provided with a circular threaded interface. By using the automatic energy-saving flow and pressure double-controlled switch, the problem that no automatic control switch for automatically controlling the pipeline pump to start and stop according to the water pressure and the flow exists at present is solved, and the automatic energy-saving flow and pressure double-controlled switch is suitable for automatically controlling the pipeline pump in a water supply system.

Description

technical field [0001] The invention relates to a pipeline pump control valve, in particular to an energy-saving double-control automatic switch for flow and pressure used to control the opening and closing of a pipeline pump. 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 an...
