Description

Target flow switch with filtering function

Technical Field

The utility model relates to the technical field of target flow switch bodies, in particular to a target flow switch with a filtering function.

Background

A target flow switch is a switching device for controlling the flow of current. It consists of a target flow tube and a control circuit. A target flow tube is a special electronic device that contains a target flow pole and a control pole inside. When the control electrode applies positive voltage, the target electrode generates current flow; when the control electrode applies a negative voltage, the current stops flowing.

The target flow switch is mainly applied to water flow detection of a pipeline, wherein the target flow switch is used for detecting water pressure in a water flow passage, when the water pressure in the water flow passage is insufficient, a pulling piece on the target flow switch can detect that the water pressure is insufficient, so that a gate is opened through a switch on the target flow switch, finally, the water pressure is restored to a stable state, when the water pressure reaches a stable value, the target flow switch transmits a signal to close the gate to protect a pipeline, however, metal impurities always flow to the vicinity of a switch at the upper end of the target flow switch in the water flow passage, and because the switch is provided with a magnet to control the on-off of the switch, the sensitivity of the switch in the switch is easily reduced by the metal impurities, the normal work of the target flow switch is affected, meanwhile, the target flow switch is not provided with a silica gel diaphragm, iron particles in water can flow to a spring and a magnet, the spring and the magnet are not rebounded, so that a blocking phenomenon occurs, and the whole switch cannot be used.
