It is magnetically coupled with the outer steel A10 for being fixed on the end drive rod A11, outer steel A10 drives drive rod A11 rotation, drive rod
The other end of A11 drives microswitch A12 movement, passes through connecting terminal A13 output signal；When the flow reduces, target piece A1 exists
Compression spring A8 effect is lower to carry out homing action, and microswitch A12 is driven to reset.It is set with this to exceed to flow in pipeline B
Detection alarm is carried out when definite value.
Above-mentioned the deficiencies in the prior art are: target type flow switch first opens outer cover A14 before installing and using, by compressing bullet
Spring adjusting screw A9 adjusts setting flow alarm function value.If field working conditions change, need to reset flow alarm function value
When, pipeline valve can only be first closed, outer cover A14 is opened and compressed spring A8 pressure is adjusted with by adjusting screw A9, or
Replace target piece A1.So adjusting is very inconvenient, and influence to produce.In addition, its temperature resistant capability is poor, internal-external magnetic steel A7, A10, fine motion
Switch A12, connecting terminal A13 etc. are directly influenced by medium temperature in pipeline B, and temperature tolerance is no more than 200 DEG C or so.
