Abstract

The invention belongs to hypervelocity impact load test technical fields, more particularly to the high-voltage cone section of light-gas gun.A kind of light-gas gun moves back plug device, and technical solution is:The side wall for moving back plug device is equipped with oil filler point, moves back the oil duct that plug device bottom surface is equipped with the annular groove for installing sealing ring and is communicated with oil filler point.After light gas battery has fired, remove the level-one pump line and two level pump line of light-gas gun, plug device will be moved back and be placed on high-voltage cone g. slice header, plug device will be moved back with hydraulic pressure and high-voltage cone section withstands realization sealing, the oil filler point for moving back plug device is connected to high-pressure oil pump, piston, to high-voltage cone intersegmental part pump oil, high-voltage cone section is exited using oil pressure by high-pressure oil pump by oil inlet.The configuration of the present invention is simple, reliability is high, and piston is difficult to exit the problem of high-voltage cone section after capable of efficiently solving light gas transmitting.

Description

A kind of light-gas gun moves back plug device

Technical field

The invention belongs to hypervelocity impact load test technical fields, more particularly to the high-voltage cone section of light-gas gun.

Background technology

The research of spacecraft shield, kinetic energy weapon and high-pressure physics etc. is required for ultra-high rates of fire technology.With it Its lift-off technology is compared, and light-gas gun is a kind of especially general device, this is because it can emit variously-shaped bullet, to bullet Quality, size and the material of ball have wide accommodation.The structure of light-gas gun as shown in Figure of description 1, including:Primary pump Pipe, piston, high-voltage cone section and two level pump line, operation principle are to utilize the light gas (hydrogen or helium) under compressive state To emit working medium, driving experiment bullet accelerates in thorax, and bullet is made to obtain required speed at gun muzzle.High-voltage cone section is light One important component of gas big gun, head is conical, and cone angle is living made of the plastic material generally between 4 ° -16 ° When entering high-voltage cone g. slice header, piston deformation velocity significantly improves, the gas before compression piston in pump line, forms extra-high voltage Gas.It is deformed very greatly since piston enters after high-voltage cone section, can be compressed in the conical section of high pressure section, be not easy to after transmitting It takes out, is insoluble problem in an experiment.

Invention content

The purpose of the present invention is:To solve the problems, such as that piston is compressed in high-voltage cone section and is difficult to exit after transmitting, provides It is a kind of to make the device that piston smoothly exits after transmitting.

The technical scheme is that:A kind of light-gas gun moves back plug device, and the side wall for moving back plug device is equipped with oil filler point, moves back plug device bottom The oil duct that face is equipped with the annular groove for installing sealing ring and is communicated with oil filler point.

After light gas battery has fired, the level-one pump line and two level pump line of light-gas gun are removed, plug device will be moved back and be placed on high pressure Section the seventh day of lunar month section is bored, plug device will be moved back with hydraulic pressure and high-voltage cone section withstands realization sealing, the oil filler point for moving back plug device is connected to high pressure oil Piston, to high-voltage cone intersegmental part pump oil, high-voltage cone section is exited using oil pressure by pump, high-pressure oil pump by oil inlet.

Advantageous effect:The configuration of the present invention is simple, reliability is high, and piston is difficult to move back after capable of efficiently solving light gas transmitting Go out the problem of high-voltage cone section.

Description of the drawings

Fig. 1 is the structural schematic diagram of the light-gas gun described in background technology;

Fig. 2 is the structural schematic diagram of the present invention;

Fig. 3 is course of work schematic diagram of the present invention.

Specific implementation mode

The present invention will now be described in detail with reference to the accompanying drawings and examples.

Referring to attached drawing 2, a kind of light-gas gun moves back plug device 5, is cylindrical structure, and the side wall for moving back plug device 5 is equipped with oil filler point 52, Move back the oil duct 53 that 5 bottom surface of plug device is equipped with the annular groove 51 for installing sealing ring and is communicated with oil filler point 52.

Referring to attached drawing 3, when light-gas gun enters emission state, high temperature and high pressure gas pushes the fortune in level-one pump line 1 of piston 2 It is dynamic.After piston 2 enters high-voltage cone section 3, since cone intersegmental part space is tapered, 2 head of piston, which is squeezed, to be started to deform, directly To piston 2 move stop, finally by tightly be extruded in cone section in.After battery has fired, level-one pump line 1 and two level pump line 4 are removed, The outlet face paste that bottom surface and the high-voltage cone section 3 of plug device will be moved back is closed, then will move back plug device with hydraulic pressure and high-voltage cone section is withstood, by being mounted on Sealing ring in annular groove 51 realizes that sealed oiling hole 52 is connect with high-pressure oil pump, and high-pressure oil pump is by oil filler point 52 to high pressure 3 inside pump oil of section is bored, piston 2 is exited into high-voltage cone section 3 using oil pressure.

In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention. All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's Within protection domain.
