Accompanying drawing explanation
Fig. 1 is a kind of structural representation of adjustable micro differential pressure switch.
Embodiment
Below in conjunction with Fig. 1, describe the utility model execution mode in detail and be described in detail.
The utility model is a kind of adjustable micro differential pressure switch of one being converted into switching signal by the Inlet and outlet water pressure difference in induction water circulation pipe, and the structure of this kind of adjustable micro differential pressure switch as shown in drawings, comprises detecting means and switch location adjusting portion.
Described detecting means is made up of body 1, body 2 and diaphragm 3, spring 12, magnet 4, magnet 5, current are flowed in the body of diaphragm both sides respectively by interface 14 and 15, when diaphragm 3 senses diaphragm both sides current pressure reduction, band moving magnet 4 moves, place because magnet 4 and magnet 5 are in homopolarity confronting coaxial line, magnetic force transmission makes magnet 5 be synchronized with the movement, contact sensitive switch contact 11, make sensitive switch 6 be in the state of being switched on or switched off, send switching signal;
Described switch location adjusting portion is made up of switch enclosure 13, sensitive switch 6, sensitive switch support 8, regulating spring 7, set screw 9, set screw 10, any operting differential pressure value can be set in particular range value, only need regulate sensitive switch 6 present position up and down, sensitive switch 6 sends switching signal to connected control appliance by connection wire 16.
Sensitive switch 6 is fixed on sensitive switch support 8, sensitive switch support 8 side is provided with screwed hole and set screw 9 is fixed, above set screw 9 with the coaxial direction of sensitive switch 6 bearing, be provided with place's screwed hole be built-in with set screw 10, switch enclosure 13 there is V-arrangement gathering sill, rotate set screw 10 and can change the upper and lower of sensitive switch 6 present position, sensitive switch 6 can be fixed on optional position by fixed screw 9.When needing the fixed position changing sensitive switch 6, unclamp set screw 9, the position of needs adjusted to by sensitive switch by adjustment set screw 10, then locking positioning screw 9.
As can be seen here, said structure of the present utility model can simply, the upper-lower position of quick adjustment sensitive switch 6 reliable fixing, by regulating the height of sensitive switch, in any one operting differential pressure value that switch performance can be made to be set in particular range value, not only property regulation function is increased compared with existing micro differential pressure switch, expand the scope of application, meet the demand of various different operating mode, and significantly improve the precision of production efficiency and properties of product, stability, sealing and firm and durable.
