Abstract
The invention relates to a spiral airbag valve which comprises a valve baseplate, a central positioning telescopic sleeve penetrating through the valve baseplate, a valve opening and closing control tower type spring connected with the top of the central positioning telescopic sleeve through a valve connecting piece, a valve closing time adjusting spring arranged in the central positioning telescopic sleeve and a spiral valve hinge arranged between the valve connecting piece and the valve baseplate, wherein normally opening exhaust holes are formed in the periphery of the valve baseplate; valve baseplate air holes are spirally formed in the valve baseplate; and a rubber sealing piece is connected onto the valve baseplate. The spiral airbag valve is simple in structure, easy to manufacture, reliable in working, light in weight and small in size, the opening and closing processes are continuous, and air passing amount meets the linear rule.
Description
Technical field
The present invention relates to air transport field, particularly a kind of spiral air bag valve.
Background technique
Special type under major engagement background supplements without in emergency circumstances utilize air-drop, the helicopter fast hoisting of follow-up support the ammunition supply means that ammunition is current the best in breaking and attacking Campaign Process, but helicopter in still spatial domain, unclosed battlefield flight of fight, land, in hovering and be vulnerable to the attack of enemy's terrestrial weapon, also have a strong impact in addition the safety of ammunition with the same impact shock that lands of air-drop parachuting.
My army and in the world not relevant research report also at present, this product equips our troops and will obtain great military benefit.
Summary of the invention
In order to solve the problem of prior art, it is a kind of simple in structure that the embodiment of the present invention provides, make easily, and reliable operation, lightweight, the spiral air bag valve that volume is little.Described technological scheme is as follows:
The embodiment of the present invention provides a kind of spiral air bag valve, and valve opening and closing control tower spring that described spiral air bag valve comprises valve floor, run through the central locating extension sleeve of described valve floor setting, be connected with described central locating extension sleeve top by valve link, the valve closing time in described central locating extension sleeve of being arranged on are adjusted spring, are arranged on the spiral valve loose-leaf between described valve link and described valve floor;
Described valve floor periphery is provided with normal open bleeder port, and on described valve floor, helical arrangement is provided with valve floor pore, on described valve floor, is connected with rubber seal.
Described spiral valve loose-leaf one end spiral is arranged on valve floor, and the spiral valve loose-leaf of spirality form mates overlapping with the valve floor pore that helical arrangement arranges; The described spiral valve loose-leaf the other end is connected with valve opening and closing control tower spring by valve link.
The beneficial effect that the technological scheme that the embodiment of the present invention provides is brought is:
1, simple in structure, make easily reliable operation;
2, lightweight, volume is little;
3, switching process is continuous, crosses tolerance and is linear rule.

Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment
The embodiment of the present invention provides a kind of spiral air bag valve, referring to Fig. 1, described spiral air bag valve comprises valve floor 1, run through central locating extension sleeve 2, the valve opening and closing control tower spring 4 being connected with central locating extension sleeve 2 tops by valve link 3 that valve floor 1 arranges, the valve closing time in central locating extension sleeve 2 of being arranged on is adjusted spring 5, be arranged on the spiral valve loose-leaf 6 between valve link 3 and valve floor 1;
Referring to Fig. 2, valve floor 1 periphery is provided with normal open bleeder port 11, and on valve floor 1, helical arrangement is provided with valve floor pore 12, is connected with rubber seal 13 on valve floor 1.
Referring to Fig. 3, Fig. 4, spiral valve loose-leaf 6 one end spirals are arranged on valve floor 1, and the spiral valve loose-leaf 6 of spirality form mates overlapping with the valve floor pore 12 of helical arrangement setting on valve floor 1; Spiral valve loose-leaf 6 the other ends are connected with valve opening and closing control tower spring 4 by valve link 3.
Referring to Fig. 5, Fig. 6, the working procedure of the spiral air bag valve that the embodiment of the present invention provides:
In the middle of spiral valve loose-leaf, source is connected with valve opening and closing control tower spring by valve link, outer source is connected with valve floor, in the time of airbag deployment, air enters air bag from normal open bleeder port, when in the middle of the moving spiral valve loose-leaf of valve opening and closing control tower spring band, edge head moves upward, spiral valve loose-leaf separates with valve floor from middle beginning gradually with spirality form, the vent of being located on valve floor demonstrates unimpeded successively, air mass flow constantly increases, flexible complete when central locating extension sleeve, the vent on base plate all demonstrates.
In the time that air bag is compressed, tower spring promotes spiral valve loose-leaf and moves downward, spiral valve loose-leaf starts to be combined with valve floor gradually from outer rim with spirality form, the vent of being located on valve floor is closed successively, air mass flow reduces gradually, until the compression of central locating extension sleeve is complete, the vent on base plate is closed, air bag continues by the slow exhaust of normal open bleeder port, until air bag compression is complete.
The elastic force of adjusting spring by the regulating valve shut-in time, can change valve and start the instantaneous air displacement in compression process at air bag, thereby plays the effect that regulates the instantaneous air pressure of air bag.
Utilize the shock-absorption air bag of this production, for the production of Review for Helicopter dress, lifting pallet, pallet possesses good buffering function of seismic resistance, support the use with the automatic rigging of fast hoisting, can realize helicopter " like a dragonfly skimming the surface of the water formula " hang fast carry, unloading ammunition, significantly improve the battlefield survival probability of helicopter, this product is also applicable to produce air-drop parachuting landing equipment.
The beneficial effect that the technological scheme that the embodiment of the present invention provides is brought is:
1, simple in structure, make easily reliable operation;
2, lightweight, volume is little;
3, switching process is continuous, crosses tolerance and is linear rule.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
