Description
Technical field
The present invention relates to a kind of membrane-repturing device, be specifically related to a kind of double containment membrane-repturing device for light-gas gun.
Background technology
Ultrahigh speed light-gas gun emission system is carried out at a high speed and the major experimental equipment of hypervelocity impact simulated experiment in " spacecraft space protection " and " body corrodes and typical target protection " research field, and this equipment can by the pellet injection of certain mass to 0 ~ 7km/s.When bullet launched by light-gas gun, the pressure of main dependence gas drives bullet, because ultrahigh speed light-gas gun generally adopts two-stage air feed, by rupture of membranes to the bullet pressurization in transmitting tube, the number of the gas pressure filled in air chamber determines the pressure of rupture of membranes, and then determines the emission rate of bullet.The effect of membrane-repturing device is to guarantee that hydrogen in piston compression cone section is until rupture of membranes process completes and hydrogen leak does not occur; avoid the rupture of membranes that causes because of pressure leakages incomplete; and then avoid the velocity of shot that therefore causes not up to standard, high temperature and high pressure gas also can be avoided the ablation of transmitting tube simultaneously.The ablation of O type circle is there is in a high voltage state in common membrane-repturing device because only having a rubber o-ring to make, high-pressure aerated rupture of membranes cannot be completed ultrahigh speed driving is carried out to bullet, also cannot carry out high pressure (100-500Mpa) inflation and cause cannot carry out ultrahigh speed pellet injection, launch cost is also higher.
Summary of the invention
The object of the invention is for solving the emission rate that cannot seal gases at high pressure rupture of membranes process and then bullet cannot be improved that existing membrane-repturing device exists and the high problem of the launch cost that therefore causes, and then a kind of double containment membrane-repturing device is provided.
The present invention is the technical scheme taked that solves the problem: a kind of double containment membrane-repturing device of the present invention comprises body, the first sealing ring, the second sealing ring, the first metallic packing ring and the second metallic packing ring, the cross section of described first metallic packing ring and the second metallic packing ring is triangle, and the cross section of described first sealing ring and the second sealing ring is circle;
Body the middle part that the end face that section is connected bored by light-gas gun is provided with the first cylindrical hole, the end face being positioned at the body outside the first cylindrical hole is provided with a circle for placing the groove of diaphragm, the bottom face of groove is provided with the first sealing ring, the end face being positioned at the body outside groove is provided with the first metallic packing ring, and groove, the first sealing ring and the first metallic packing ring three are coaxially arranged;
The middle part of the end face be connected with transmitting tube of body is provided with the second cylindrical hole, and the bellmouth that be communicated with coaxial with the two is provided with between first cylindrical hole and the second cylindrical hole, the larger diameter end of bellmouth is communicated with the first cylindrical hole, the smaller diameter end of bellmouth is communicated with the second cylindrical hole, the end face being positioned at the body in the outside of the second cylindrical hole is separately installed with the second sealing ring and the second metallic packing ring, and the second sealing ring and the second metallic packing ring are coaxially arranged.
The invention has the beneficial effects as follows: one, structure of the present invention is simple, and reasonable in design, the present invention and high pressure light-gas gun are bored section and be connected, adopt the dual sealing manner of becket and O RunddichtringO, sealing is good, can make fully to compress by the hydrogen in pipe, makes Rupture of Membrane pressure higher; The present invention is connected with transmitting tube, also the dual sealing manner of becket and O RunddichtringO is adopted, the gas after rupture of membranes can be made all to act on body, body is made to reach ultrahigh speed, first cylindrical hole of the both ends of the surface of body of the present invention is different with the aperture of the second cylindrical hole, rupture of membranes effect can be increased, transmitting tube ablation can also be prevented, reduce cost; Two, the invention solves high pressure light-gas gun cone section and the superhigh pressure sealing at film contact place and the superhigh pressure sealing sex chromosome mosaicism of membrane-repturing device and transmitting tube contact position, the present invention launches front pump line and to vacuumize and secondary cone section all needs good sealing when filling hydrogen, membrane-repturing device installs becket (cross section is triangle) and O RunddichtringO can realize sealing effectiveness additional; In emission process, when wanting to launch comparatively low velocity, when namely before rupture of membranes, Hydrogen Vapor Pressure is less, O RunddichtringO self just can play good sealing effectiveness.But when wanting to launch high speed, can reach the hyperpressure of 500 MPas before rupture of membranes in high-voltage cone section, at this moment O RunddichtringO can be damaged under the effect of super high-pressure hydrogen, and reveal hydrogen, cause energy waste, bullet speed is not up to standard, cannot complete ultra-high rates of fire.Install the Hydrogen Vapor Pressure that becket (cross section is triangle) can sustain superelevation additional, but metal triangular ring cannot keep the seamless of height to contact with contact position, can leak, cannot realize sealing when vacuumizing or be filled with hydrogen.Present invention incorporates the advantage of O RunddichtringO and becket (cross section is triangle), have devised a kind of brand-new sealing means, namely adopt becket and O RunddichtringO jointly to use, reach the effect of high pressure or superhigh pressure sealing, three, the present invention has under the original experiment condition of maintenance, do not increase any device and improve the aeration quantity making hydrogen in cone section, Rupture of Membrane pressure is increased, thus effectively improve the limit velocity of pellet injection, light-gas gun can be made to bore instantaneous air pressure in section when reaching 100-500Mpa high pressure, rupture of membranes process is air tight, the bullet of certain mass is made to accelerate to 7km/s, efficiently solve existing membrane-repturing device, the ultra-high rates of fire of 7km/s cannot be completed, improve the emission effciency of light-gas gun, reduce launch cost, launch cost is compared existing cost 0.5 ten thousand and is reduced 10%-30%.
