The operation instruction of the utility model is as follows:
It as shown in Fig. 2, is that the reception pressure of pressure switch is in detection pressure and sets initial conditions below, spring
Seat 6 under spring force, push down the contact 18 of microswitch 12, according to original by the left end position in movable stroke
It manages graphical diagram (such as attached drawing 4 and attached drawing 5), the contact one, contact two of pressure switch disconnect at this time, and contact one, contact three are connected,
The dual-colored LED lamp 1 of 14 left and right sides of connector assembly and 23 display color of dual-colored LED lamp are green at this time.
It is acted on the end face of plunger 5 after perforation aperture of the pressure oil by 4 centre of damper, pressure oil makes plunger 5
The thrust of generation is transmitted on the left of spring base, and at this moment, spring 7 is conditioned the power that the compression of screw rod 10 generates, and passes through 8 effect of spring pressure
On the right side of spring base 6, when the thrust that plunger 5 generates is greater than the adjustment force of spring 7, plunger 5 and spring base 6 are towards adjusting spiral shell
10 direction of bar is mobile, and spring base 6 moves right, the microswitch contact 18 pushed down under reset condition is decontroled, fine motion is caused to be opened
It closes 12 states to switch, contact changes, and the contact one, contact three of pressure switch disconnect at this time, contact one, contact two
It connects, the dual-colored LED lamp 1 of 14 left and right sides of connector assembly and 23 display color of dual-colored LED lamp are red at this time.
If pressure declines suddenly, the thrust of the generation on plunger 5 is less than the adjustment force of spring 7, plunger 5 and spring base 6
It is mobile towards 4 direction of damper, the microswitch contact 18 being released is pushed down again, contact changes, contact one, contact
Two disconnect, and contact one, contact three are connected, and dual-colored LED lamp 1 and 23 display color of dual-colored LED lamp become green again.
As shown in figures 4 and 5, function symbol description are as follows: spring force setting is completed, before pressure does not reach control point
(such as attached drawing 4), contact one, contact three are connected, and contact one, contact two disconnect, LED light bright green；Pressure is higher than control point
(such as attached drawing 5), contact one, contact three disconnect, and contact one, contact two are connected, LED light shiny red.
The utility model mainly solves the problems, such as, external in the conversion of pressure switch signal
Without instruction, it cannot be intuitively in from external observation relay and be switched on or switched off state.When dual-colored LED lamp display color is green
When, indicate that current pressure relay is in detection pressure set points or less；When dual-colored LED lamp display color is red, indicate
Relay is in high-pressure work state.So as in use, the intuitive working condition for showing pressure switch, to production
And maintenance bring it is safe and convenient, or even may be configured as warning pressure alarm, when red light is bright, expression pressure be in superpressure shape
State solves the problems, such as that current similar product signal output state can not be shown.
The utility model is simultaneously not limited to the embodiments described above, and other any spirit without departing from the utility model are real
Made changes, modifications, substitutions, combinations, simplifications under matter and principle, should be equivalent substitute mode, be included in practical
Within novel protection scope.
