Target plate flow switch and its target plate structure

Abstract

The invention discloses a target slice-type flow switch and a target slice structure thereof. The target slice structure of the target slice-type flow switch comprises a connecting rod and a target slice. One end of the connecting rod is provided with two baffle plates. An inserting groove is formed between the two baffle plates. The target slice is fixed into the inserting groove. The target slice structure of the target slice-type flow switch has following beneficial effects: the target slice is fixed into the inserting groove and the two baffle plates are located on two sides of the target slice; the baffle plates on two sides of the target slice help to eliminate partial impact force of a fluid so that impact force to the target slice is reduced; therefore, the bending amplitude of the target slice is reduced and the chance of deforming the target slice is decreased; and therefore reliability of the target slice-type flow switch is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of flow detection, and more specifically relates to a target plate type flow switch and a target plate structure thereof. Background technique [0002] The flow switch is used to detect the flow of water, gas, oil and other media in the media pipeline. There are many types of flow switches, among which the target plate type flow switch is widely used. The working principle of the target-type flow switch is: the target is set in the medium pipeline, and when the fluid flows, it impacts the target, and the target drives the micro switch to send out a flow signal. [0003] In the target-type flow switch, the target is connected to the micro switch through the connecting rod, and the target is fixed on one side of the connecting rod. With long-term use, the target is impacted by the fluid for a long time, and the probability of bending deformation is relatively high. As a result, the reliability of the target ...

AI Technical Summary

Problems solved by technology

[0003] In the target-type flow switch, the target is connected to the micro switch through the connecting rod, and the target is fixed on one side of the connecting rod. With long-term use, the target is impacted by the fluid for a long time, and the probability of bending deformation is relatively high. Resulting in lower reliability of the target plate flow switch

[0004] In addition, during engineering debugging, the fluid will impact the target irregularly, which will also lead to a higher probability of bending and deformation of the target, and the reliability of the target flow switch is low.

[0005] In addition, the target piece is fixed on one side of the connecting rod, and the fluid impacts the target piece for a long time, which makes the target piece less resistant to bending deformation, resulting in the target piece being easily bent, deformed, or even broken, and has a shorter service life
