Problems solved by technology

[0003] The deficiency of the above-mentioned prior art is: before installation and use of the target flow switch, the outer cover A14 is opened, and the flow alarm value is adjusted and set by the compression spring adjustment screw A9
Therefore, adjustment is inconvenient and affects production
In addition, its temperature resistance is poor, and the inner and outer magnetic steel A7, A10, micro switch A12, terminal A13, etc. are directly affected by the temperature of the medium in the pipe B, and the temperature resistance does not exceed about 200 °C

Abstract

The invention discloses an online adjustable target flow switch, which comprises a pipe barrel (1), a pipe barrel flange (10), a target sheet (2), a rotating supporting plate (20), a rotating supporting plate seat (22), a target rod (3), a sliding column (30), an internal magnetic steel block (31), a compressed spring (4), a compressed spring adjustment device (5), a shell (6), a microswitch (7), an external magnetic steel block (71), a transmission rod mechanism (8) and a wiring terminal (9), wherein the shell (6) is fixedly arranged on the pipe barrel (1) through a support and the pipe barrel (1) is made to be placed in a groove (60) opened in the end surface of the shell (6). The sealing performance is reliable; and when a flow alarming value needs to be set again, a pipeline valve does not need to be closed, and an alarming point can be directly adjusted in the field and set.

Description

technical field [0001] The invention relates to a target flow switch, which is a target flow switch capable of resetting the flow alarm value in a pipeline on-line. Background technique [0002] Current target flow switches such as figure 1 As shown, it consists of target piece A1, cam A2, cam hinge bracket A3, target rod A4, casing A5, slide tube A6, built-in magnetic steel A7, compression spring A8, compression spring adjustment screw A9, external magnetic steel A10, transmission rod A11, micro switch A12, connection terminal A13, outer cover A14, butt flange A15 constitute. The target piece A1 is placed in the horizontal pipe B, and the target piece A1 is driven by the fluid in the pipe B to rotate the cam A2, and the target rod A4 and the sliding cylinder A6 are lifted upwards, and the built-in magnetic steel A7 fixed in the sliding cylinder A6 is fixed on the The outer magnetic steel A10 at the end of the transmission rod A11 is magnetically coupled, the outer magneti...
