Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

Provide a most preferred embodiment below:

A kind of used for air compressor baroswitch,

Comprise cover cap 15, base plate 11, support 1, base 13, differential pressure adjusting device as Fig. 1, Fig. 2, used for air compressor baroswitch shown in Figure 3, pressure transducer and unloading valve 12, pressure transducer are made of diaphragm 17 and transmission device.Screw press 26 is arranged in the transmission device, put pressure reduction adjustable lever 24 successively, support pressing plate 8, pressure adjusting spring 32, spring bearer plate 22 compress with look nut 21 at last, respectively have a pore on base plate 11 and the base 13.Put into diaphragm 17 in the base 13 successively, compressing tablet 18, pallet 19, support 1 passes base plate 11 and is stuck in base 13 both sides, with four base screws 23 with support 1, base 13, diaphragm 17, compressing tablet 18, pallet 19 tightens together, put into sensing head 27, the sensing head hole is put in screw press 26 bottoms, support 1 and support pressing plate 8 rivet clasps together, be with control panel between support pressing plate 8 and the base plate 11, the stationary axle 4 of control panel 2 is put into U-groove bevel on the screw press 26, with a rotatingshaft 3 springboard 2 control panels 1 are nested together with support 1, and block two ends with jump ring 6, control panel 2 is connected with springboard 5 usefulness torsion springs 6, and springboard 5 one ends are packed in the hook of moving contact frame 4.Two cover cap screw of switch cover cap 15 usefulness are on base plate 11, and manually turn-knob 16 is stuck in the hole at cover cap top.Switch fixed contact sheet is stuck in the corresponding groove of control panel, and moving contact sheet 1 usefulness is blocked spring 29 and is stuck in the moving contact frame 7 corresponding holes.

When Pneumatic pipe cleaner is crossed base 13 and is acted on the diaphragm 17, diaphragm 17 becomes air pressure the position change that converts pallet 19 to, sensing head 20 on the pallet 19 impels this position change the control panel 2 of switch by 5 actions of torsion spring 6 pulling springboards by screw press 26, and then the transmission system work of pushing switch, fixed contact 31 and moving contact 28 disconnection accordingly (or closed) was sent electrical signal and was controlled the work of the capable mechanism of corresponding pad under the action of moving contact frame 7 this moment.When the action of springboard 5, moving contact frame 7 can be with the unloading valve 12 beginning releases of tipping under base 13, when system's (gas holder) hypotension is arrived to a certain degree, transmission system resets, moving contact frame 7 resets, thereby power supply is connected air compressor automatically and is restarted running, and unloading valve 12 cuts out simultaneously.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
