Specific implementation mode
The present invention is further described with preferred embodiment below in conjunction with the accompanying drawings.
Shown in Fig. 1 to 2, involved by the present embodiment it is a kind of it is initial have pressure energy self-locking and can hand-reset signal it is anti-
Device is presented, includes the valve body 3 being made of case 1 and valve seat 2, there is valve chamber 4 in valve body 3,2 bottom of the valve seat offers and valve
The air admission hole 5 that chamber 4 is connected, 1 top of the case offers pilot hole 6, piston rod 7, piston is slidably connected in the valve chamber 4
7 lower end of bar has piston head 71, the baffle ring 8 being embedded in valve chamber 4 is arranged on the piston rod 7, between baffle ring 8 and piston head 71
Equipped with elastic element 1,7 upper end of the piston rod is also connected with the mandril 10 being slidably connected in pilot hole 6, mandril 10 it is upper
End face protrudes from the upper surface of the case 1；It is connected with switch fixed seat 11 in the side wall surface of the case 1, switchs fixed seat
There is the rolling groove 12 being connected to the valve chamber 4,12 side of rolling groove to be equipped with the fine motion being fixed in switch fixed seat 11 in 11
Switch 13, the other side have the wide-mouth slot 14 being opened on 10 side wall of the mandril, and being sticked on the lower cell wall of wide-mouth slot 14 has rolling
The dynamic ball 15 being connected in the rolling groove 12, is equipped with elastic element 2 16 between ball 15 and microswitch 13；The case 1
Side wall surface on be further opened with side opening 17, be embedded in side opening 17 can move left and right from lock unit 18, from 18 one end of lock unit
10 lower face of mandril is abutted, the other end protrudes from the outside wall surface of the case 1；The microswitch 13 is normally closed microswitch.
Further, the case 1 is arranged and is rotatably coupled on valve seat 2, is also opened up on the side wall of the case 1
There are screw mounting hole 19,19 internal thread of screw mounting hole to connect the stop screw 1 that the restricted case 1 rotates.
Further, the side opening 17 have internal thread, it is described from lock unit 18 be the limit being threaded on side opening 17
Position screw two.
Further, the lower cell wall of the wide-mouth slot 14 and vertical plane are at 30 degree of angles.
Further, the side of the piston head 71 offers annular groove 21, and O-ring 22 is embedded in annular groove 21.
Further, the elastic element 1 and elastic element 2 16 are compressed spring.
In the present embodiment, it has been initially under the conditions of pressure, and 10 lower face of mandril is not abutted from 18 one end of lock unit, such as
Shown in Fig. 2, there are the medium of certain pressure, pressure promotion piston head 71 to overcome the effect of elastic element 1 in the valve chamber 4 of valve body 3
Power, and the mandril 10 being connected by screw thread with piston rod 7 is pushed, ball 15 is pushed out wide-mouth slot 14, squeezes elastic element 2 16,
To make the action of normally closed microswitch 13 go off, signal feedback device does not export feedback signal；When pressure medium release or
Person's pressure medium less than on piston head 71 when the reaction force of elastic element 1, piston rod 7 under the action of elastic element 1,
Pulled down mandril 10, since mandril 10 is equipped with skew wall, ball 15 is pushed back by elastic element 2 16 in wide-mouth slot 14, normally closed micro-
Dynamic switch 13 is closed, and exports feedback signal, and at this time under no outer force effect, signal feedback device can continue output feedback letter
Number, it need to manually pull and be stayed on mandril 10 in 1 outer length of case to 17 top of side opening（I.e. from 18 top of lock unit）It can
It is set no longer to export feedback signal.It can also be by being pulled to 17 top of side opening in 10 lower face of mandril, then by turn from lock unit
18（That is stop screw two）So that 10 lower face of mandril is abutted from 18 one end of lock unit, mandril 10 can not continue to move down, and believe
Number feedback device, which is maintained at, does not export feedback signal state, as shown in Figure 1.
In signal feedback device working condition, medium is entered by air admission hole 5 in the valve chamber 4 of valve body 3, will be as lived in Fig. 1
Stopper rod 7 pushes upwards, since piston rod 7 is equipped with O-ring 22, between pressure is more than the active force and each component of elastic element 1
When frictional force, shipper pole moves mandril 10 to piston rod 7 on the whole, and the ball 15 in wide-mouth slot 14 is extruded wide-mouth slot 14, to
Compression elastic element 2 16, elastic element 2 16 act on fine motion element 13, so that fine motion element 13 is in and disconnect because being under pressure
State does not export feedback signal at this time.
In turn, when pressure medium is released or pressure medium is less than the reaction force of elastic element 1, elastic element
One 9 pull down piston rod 7, and piston rod 7 is also moved down since screw thread is connect with mandril 10 with the movement of piston 7 simultaneously,
In moving process, the ball 15 for being extruded wide-mouth slot 14 originally comes back in wide-mouth slot 14, and elastic element 2 16 is no longer influenced by
It squeezes, microswitch 13 is closed, and exports feedback signal.In the case where not borrowing other outer force effects, this signal feedback device can be persistently defeated
Go out feedback signal, to achieve the effect that self-locking.
And, stop output feedback signal if you need to this signal feedback device again, then needs manually mandril 10 to be pulled to be exposed to outside case 1
Body portion, after being pulled on side opening 17, rotary self-locking unit 18 is limited, at this time fine motion element 13 in such as Fig. 1, mandril 10
It disconnects, the output of feedback-less signal.
The present invention can use under conditions of primary condition is to have pressure, and after pressure medium release or pressure medium is low
When to a certain degree, in the case that not by external force, can constant feedback signal, that is, self-locking requirement, can make it after manual reset
Feedback signal is no longer exported, is used for next time.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
