Abstract

The invention provides a novel water pump pressure control device, which includes a water inlet and a water outlet; a check valve assembly is arranged between the water inlet and the water outlet; a pressure sensor is arranged at the water inlet; the pressure sensor is connected with the water outlet. The control module is electrically connected; the check valve assembly includes a magnet, and a reed switch is arranged next to the magnet; the reed switch is electrically connected to the control module; the control module is electrically connected to the water pump; the water pump pressure control device passes The pressure sensor detects the pressure in the pipeline, and then uses the single-chip microcomputer to control the start and stop of the water pump; and uses the magnet on the check valve and the reed switch on the control board to detect the water flow in the pipeline, and displays the pressure and other information through the digital tube; The check valve structure with a raised silicone sleeve ensures that the controller can keep the water pump running with a small flow rate, which improves the service life of the water pump.

Description

technical field [0001] The invention relates to the technical field of pressure control devices, in particular to a pressure control device for a water pump. Background technique [0002] Currently used electric water pumps, in order to achieve automatic control, a pressure controller is set in the pipeline. When the water pressure is lower than the set value, the pressure controller is connected to the power supply of the water pump motor, and the water pump works; when the water pressure reaches the upper limit of the set value , the pressure controller cuts off the power supply of the water pump motor, the water pump stops working, and the purpose of automatic control is realized. The current pressure controller cannot control the water flow, especially when the source is short of water and the water flow is small, it cannot automatically adjust and cut off the power supply of the water pump to achieve the protection purpose. Contents of the invention [0003] In order...
