As shown in Figure 4, to combine Fig. 5 visible, is additionally provided with and is driven by this STATEMENT OF FEDERALLY SPONSORED and UNICOM or cut off circuit in installation cavity
Switch.
In the present embodiment, switch includes first inserted sheet the 12, second inserted sheet the 11, the 3rd inserted sheet 17, installs and offers respectively on lid 1
There is the first slot 104 for installing the first inserted sheet 12, for installing the second slot 105 of the second inserted sheet 11 and for pacifying
Fill the 3rd slot 106 of the 3rd inserted sheet 17.
As seen from Figure 5, first inserted sheet the 12, second inserted sheet 11 and the 3rd inserted sheet 17 are the most L-shaped.Wherein, the first inserted sheet 12 has
Being inserted vertically into portion and level connection joint portion, the second inserted sheet 11 has a circuit communication portion 1101 of the portion of being inserted vertically into and level, and the 3rd
Inserted sheet 17 has the circuitry cuts portion 1701 of the portion of being inserted vertically into and level；First inserted sheet the 12, second inserted sheet 11 and the 3rd inserted sheet 17
The portion of being inserted vertically into be respectively and fixedly installed in first slot the 104, second slot 105 and the 3rd slot 106, be respectively inserted vertically into portion
Two sides on all with paired locking tooth 18, the logarithm of locking tooth 18 can the most specifically be arranged, locking tooth 18
For preventing generation between first inserted sheet the 12, second inserted sheet 11 and the 3rd inserted sheet 17 and installation lid 1 from loosening.
As shown in figs. 4 and 7, to combine Fig. 5 and Fig. 8 visible, and the first slot 104 is positioned at installation lid side, the second slot 105
Be positioned at the opposite side installing lid with the 3rd slot 106, the second slot 105 is relative with the 3rd slot 106 and be arranged in parallel, and first inserts
Groove 104 offer direction and the second slot 105 and the 3rd slot 106 to offer direction perpendicular；Thus, the first inserted sheet 12,
After two inserted sheets 11 and the 3rd inserted sheet 17 are installed, circuit communication portion 1101 and circuitry cuts portion about 1701 and be arranged in parallel, both
Between distance be the differential movement of switch, the level connection joint portion of the first inserted sheet 12 is fixed with middle reed 10, in the middle of this
The free end of reed 10 extends between circuit communication portion 1101 and circuitry cuts portion 1701.
In the present embodiment, the differential movement of switch is by the circuit communication portion 1101 of the second inserted sheet 11 and the electricity of the 3rd inserted sheet 17
Distance between road cutting portion 1701 determines, makes the diversity of difference journey be controlled, it is ensured that the concordance of product.
In the present embodiment, middle reed 10 includes elastic joint part 1001, and the fixing end of elastic joint part 1001 is fixed on
In the level connection joint portion of the first inserted sheet 12, the free end of elastic joint part 1001 then extends to circuit communication portion 1101 and circuit is cut
Between disconnected portion 1701, and with circuit switching part 1003 (i.e. contact).When circuit switching part 1003 contacts circuit communication portion 1101
Time, switch is in connected state, and when circuit switching part 1003 contacts circuitry cuts portion 1701, switch is off.
According to specific needs, circuit communication portion 1101 or circuitry cuts portion 1701 can also arrange contact, in order to reduce
Resistance in circuit, the electric current in intensifier circuit, improve switch susceptiveness.
As seen from Figure 5, elastic joint part 1001 offers installing hole, be provided with in this installing hole for ordering about circuit switching
The elastic actuating member 1002 of portion 1003 movement between circuit communication portion 1101 and circuitry cuts portion 1701, this elastic actuating member
The fixing end of 1002 is wholely set with the fixing end of elastic joint part 1001, and the free end of this elastic actuating member 1002 connects with elastic
Connect to abut between the free end in portion 1001 and have waist drum spring 13.
As shown in Figure 8, to combine Fig. 4 visible, and the middle part of elastic actuating member 1002 offers the linkage hole passed for connecting rod 14
1004；Further, in the side of elastic actuating member 1002 away from membrane 6, connecting rod 14 periphery is provided with for extruding outside linkage hole 1004
3rd spacing ring 1402 of end face.
When connecting rod 14 moves to mounting seat 2 direction, the 3rd spacing ring 1402 can extrude the outer face in linkage hole 1004, pushes away
Dynamic elasticity drive division 1002 moves to mounting seat 2 direction.
As shown in Figure 5, to combine Fig. 4 visible, and reset seat 7 is provided with projection 703 towards the end face of connecting rod 14, when reset seat 7
When moving to installation lid 1 direction, projection 703 can extrude elastic actuating member 1002, promotes elastic actuating member 1002 to installing lid 1 side
To movement.
Meanwhile, reset seat 7 periphery also sets up two limited blocks being oppositely arranged 702, and pressing plate 8 inner surface is provided with spacing with this
The bar shaped stopper slot 802 that block 702 matches, this bar shaped stopper slot 802 is axial arranged along pressing plate 8.Limited block 702 is spacing with bar shaped
Groove 802 coordinates, and is possible to prevent reset seat 7 to circumferentially rotate when sliding, it is ensured that projection 703 can be directed at elastic actuating member
1002。
Under the promotion of reset seat 7 or connecting rod 14, elastic actuating member 1002 swings back and forth, and affects waist drum spring 13, thus carries
The circuit switching part 1003 of dynamic elasticity connecting portion 1001 free end comes between circuit communication portion 1101 and circuitry cuts portion 1701
Switchback is changed.
During work, first the pipe pawl 5 at mounting seat two ends is connected pipeline, it is assumed that fluids within pipes is gases at high pressure.High pressure
Gas enters the fluid cavity 200 of mounting seat 2, and now pipe pawl compresses sealing ring 3, prevents fluid cavity 200 from leaking gas.Gases at high pressure pass through
Fluid passage 202 enters the second installation cavity 201, and owing to the periphery of diaphragm 6 is pushed down in pressing plate 8 sealing, gas can not pass through diaphragm 6.
Under the flexible drive of pressure spring 15, the 3rd spacing ring 1402 of connecting rod 14 props up elastic actuating member 1002, makes circuit switch
Portion 1003 contacts with circuit communication portion 1101, and high-voltage switch gear is in connected state.
When air pressure reaches trigger value, the thrust that gases at high pressure produce is more than the elastic force of pressure spring 15, and gases at high pressure drive
Making diaphragm 6 move to installing lid 1 direction, diaphragm 6 drives reset seat 7 to be synchronized with the movement.Projection 703 in reset seat 7 props up elasticity
Drive division 1002, near the surface of mounting seat 2, promotes elastic actuating member 1002 to move to installing lid 1 direction.Elastic actuating member
1002 affect waist drum spring 13, drive circuit switching part 1003 to separate with circuit communication portion 1101, and with circuitry cuts portion 1701 phase
Contact, now, high-voltage switch gear is off.
On the contrary, when in fluid cavity, the gas pressure of 200 is less than trigger value, the thrust that gases at high pressure produce is less than pressure regulation bullet
The elastic force of spring 15, pressure spring 15 orders about connecting rod 14 and moves to the direction of mounting seat 2, and connecting rod 14 promotes reset seat 7 to reset.With
Time, the 3rd spacing ring 1402 of connecting rod 14 props up the elastic actuating member 1002 surface near installation lid 1, promotes elastic actuating member
1002 move to mounting seat 2 direction.Elastic actuating member affects waist drum spring 13, drives circuit switching part 1003 and circuitry cuts portion
1701 separate, and contact with circuit communication portion 1101, and now, high-voltage switch gear is in connected state.
