Abstract
The invention provides a short stroke quick release valve for starting detonating impact, which comprises a valve body and a valve core, wherein a release passage communicated with a pressure storing bottle is arranged in the valve body; a control passage communicated with the release passage is also arranged in the valve body; the valve core can be arranged in the control passage in a sliding manner; a front valve cap is sealed at one end of the control passage; a cavity is formed between the front valve cap and the valve core; the cavity is filled with a high pressure gas generating agent; an electric ignition head is arranged in the high pressure gas generating agent; the valve core separates the release passage in normal state; and when the high pressure gas generating agent is ignited by the electric ignition head, the produced high pressure gas pushes the part with releasing holes on the valve core to move the part to the release passage to form a passage. The electric ignition head and the high pressure gas generating agent form a high-pressure source generating device; the release valve is small in size, large in motive power and good in controllability; a buffer cushion block is arranged at and a self-locking hole is formed in the end part of the valve core; and the high-speed impacting and rebounding of the valve core can be eliminated.

Wherein: described rear valve gap is provided with relief hole.
Wherein: be provided with self-locking buckle at described spool by described rear valve gap side, have in described self-locking buckle by the self-locking spring compressed, described control channel is provided with self-locking hole by described rear valve gap side.
Compared with prior art, the beneficial effect that the present invention has is:
1, igniting reaction is fast, and the opening time is less than 10 milliseconds.
2, electric igniter and pressurized gas propellant form high-voltage power supply generating device, and volume low-power is large, and controllability is good.
3, spool end has cushion pad and self-locking hole, can eliminate high speed impact and the bounce-back of spool.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the short stroke quick release valve opened is impacted in a kind of detonation provided by the invention.
Description of reference numerals: valve body 1; Front valve gap 2; Wiring terminal 3; Electric igniter 4; Pressurized gas propellant 5; Cavity 6; Seal ring 7; Release aperture 8; Spool 9; Self-locking buckle 10; Self-locking spring 11; Self-locking hole 12; Rear valve gap 13; Cushion pad 14; Medicament 15; Storage pressure bottle 16.
Embodiment
As shown in Figure 1, the invention provides a kind of detonation and impact the short stroke quick release valve opened, there is valve body 1 and spool 9, described valve body 1 is threadedly attached to storage pressure bottle 16 or other pressure pipings, the upper space of described storage pressure bottle 16 is pressure energy-storage, lower space is medicament 15, and medicament 15 can be liquid or pulvis.
The release channel (in vertical setting in Fig. 1) being communicated to described storage pressure bottle 16 is provided with in described valve body 1, the control channel (being that level is to arranging in Fig. 1) of passing through mutually with described release channel and being communicated with also is provided with in described valve body 1, described spool 9 is slidably disposed in described control channel, described spool 9 cuts off described release channel under normal conditions, and the medicament 15 in described storage pressure bottle 16 cannot be discharged.
A front valve gap 2 is enclosed in one end of described control channel by seal ring 7, and a cavity 6 is formed between described front valve gap 2 and described spool 9, in the present embodiment, the interior room being communicated to spool 9 is formed in described front valve gap 2, described interior room can be considered a part for above-mentioned cavity 6, pressurized gas propellant 5(is filled with as black gunpowder) in described interior room, electric igniter 4(is provided with as electric detonator) in described pressurized gas propellant 5, the part that described electric igniter 4 stretches out described front valve gap 2 is provided with wiring terminal 3, for connecing startup power supply.
After one, valve gap 13 is fixed on the other end of described control channel, is abutted between described spool 9 side with described rear valve gap 13 by cushion pad 14, makes described spool 9 cut off described release channel under normal conditions.
When described startup power work, described electric igniter 4 is allowed to generate heat, ignite described pressurized gas propellant 5, high pressure air cognition is full of described cavity 6 instantaneously, promote spool 9 to move right at a high speed, allow part spool 9 with release aperture 8 move on described release channel and form path, the medicament 15 in described storage pressure bottle 16 can be discharged fast.
Now, be provided with described cushion pad 14 between described spool 9 and described rear valve gap 13, can part of impact force be eliminated.In addition, described rear valve gap 13 can also arrange relief hole (not giving diagram), when spool 9 impacts at a high speed, when the air in space occupied by cushion pad 14 is compressed, can a part be leaked away to the right.
In order to prevent spool 9 bounce-back after the described rear valve gap 13 of collision, by described rear valve gap 13 side, self-locking buckle 10 is installed at described spool 9, have in described self-locking buckle 10 by the self-locking spring 11 compressed, described control channel is provided with self-locking hole 12 by described rear valve gap 13 side, when described spool 9 drives described self-locking buckle 10 to move right to described self-locking hole 12 position, self-locking spring 11 boosts self-locking buckle 10 and sticks into self-locking hole 12, thus pinning spool 9 limits the rear resilience of its impact.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection scope of the present invention.
