Specific embodiment
Following further describes the present invention with reference to the drawings.
The present invention proposes a kind of long-range pressure relief of solid-liquid rocket, is used for the long-range pressure release of high pressure gas, including remote
Journey pressure release electromagnetic valve 1, discharges component 3 at pressure relief pipe 2, as shown in Figure 1.
The long-range pressure release electromagnetic valve 1 is discharged for controlling high pressure gas in gas cylinder, and arrival end connects gas cylinder, outlet end
Pressure relief pipe 2 is connected, high pressure gas in gas cylinder is drained to by long-range pressure release electromagnetic valve 1 by pressure relief pipe 2 and is installed on solid-liquid fire
Discharging at component 3 on arrow engine covering.
The pressure relief pipe 2 selects stainless steel material, is made of bend pipe 201 and welding tip 202, as shown in Figure 2.Wherein,
201 arrival end of bend pipe is co-axially mounted and is connected to the outlet end of long-range pressure release electromagnetic valve 1, is fastened between the two by nut, simultaneously
Circumferential seal is realized by bulb；The outlet end of bend pipe 201 is co-axially mounted and is connected to welding tip 202, equally passes through between the two
Nut fastening, and circumferential seal is realized by bulb；Welding tip 202 is used to connect to discharge component 3.
The component 3 that discharges includes for high pressure gas to be expelled to outside solid-liquid rocket covering.Discharge the packet of component 3
It includes and discharges mouthful nut 301, adjustment gasket 302 and diaphragm 303, as shown in Figure 1；Wherein, mouthful nut 301 and adjustment gasket are discharged
302 select stainless steel material, and diaphragm 303 selects pure aluminum material.As shown in figure 3, discharging mouthful nut 301 is tubular structure, have
The small internal diameter section in top and lower part large diameter section；Large diameter section inner hole is from top to bottom successively designed as unthreaded hole section 304 and thread segment
305.For placing diaphragm 303 in unthreaded hole section 304；304 internal screw thread of thread segment is equipped with adjustment gasket 302, and adjustment gasket 302 can
It is designed as multiple, and is designed as different height, the adjustment gasket 302 of height is suitble to by selecting, welded to adjust pressure relief pipe 2
Error caused by technique, convenient for discharging the connection of component 3 Yu covering.
Isolation of the diaphragm 303 for gas inside and outside solid-liquid rocket covering under normal circumstances.303 surface of diaphragm
It is carved with annular triangular section channel 306, is ruptured under 2MPa pressure, for the seal isolation inside and outside covering under normal circumstances.Make
After long-range pressure release electromagnetic valve 1 opens, high pressure gas, which enters, to be discharged in component 3, and diaphragm 303 is made to be under pressure (2MPa) rupture
Afterwards, high pressure gas is exported.The adjustment gasket 302 is for diaphragm 303 to be compacted in unthreaded hole section 304；Adjusting gasket 302 is
Cylindrical structure, center are provided with interior hexagonal through-hole, are used to form gas circuit and pass through convenient for high pressure gas, while convenient for by tool reality
Now adjust the threaded connection of gasket 302；Adjustment gasket is screwed by the interior hexagonal screw hole that tool is inserted into adjustment gasket 302 as a result,
302, diaphragm 303 is pressed in unthreaded hole section 304, female end and 204 port of welding tip for discharging mouthful nut 301 are then passed through
Fixation is tightened in the external screw thread cooperation of outer wall design, realizes the fixation discharged between component 3 and pressure relief pipe 2.Above-mentioned small internal diameter section
Outer diameter is less than the outer diameter of large diameter section, thus forms annular step surface between small internal diameter section and large diameter section outer wall；Small internal diameter section
It is installed in the through-hole opened up on covering, the positioning between covering is realized by step surface, and make to be exposed at the top of small internal diameter section
Covering outer wall；Opening diameter is greater than 1~2mm of small internal diameter section outer diameter on covering.Small internal diameter section top exterior walls design has external screw thread, leads to
It crosses between locking nut 4 and external screw thread after cooperation tightens, mouthful nut 301 will be discharged and be fixed on solid-liquid rocket covering, into
And realize the fixation discharged between component 3 and solid-liquid rocket covering.4 upper surface of locking nut is circumferentially evenly distributed with 4 apertures, uses
In the threaded connection for realizing locking nut 4 by tool.
Inner support is also equipped between the step surface and covering medial surface of above-mentioned small internal diameter section, outside locking nut 4 and covering
Outer support is installed between side；Wherein inner support is annular, is made of softer material, such as polytetrafluoroethylene (PTFE), for filling
The gap between the step surface of mouthful nut 301 and covering medial surface is discharged, makes to discharge component 3 and covering medial surface compresses.Outer support 5
For guaranteeing to have certain aerodynamic configuration outside covering, reduce influence of the covering outer lug to rocket aerodynamic force；Also it is used to fill out simultaneously
The gap for filling outer side Yu locking nut 4 keeps locking nut 4 and outer side face pressure tight.The body portion 501 of above-mentioned outer support 5
Diameter is greater than 1~2mm of opening diameter on covering；And as shown in figure 4, the rear and front end in body portion 501 is designed as tilting towards covering
Inclined-plane 502, and end is designed as tip 503, and 601, tip 503 to body portion rounding off is integrally formed, and is thus subtracted as far as possible
The small influence to aerodynamic force.501 center opening of body portion is for covering in the small internal diameter section for discharging mouthful nut 301, and tapping is set
In respect of ring-shaped step, for placing locking nut 4；After locking nut 4 is tightened, the inner ring of locking nut 4 outer ring and ring-shaped step
Face clearance fit, and 4 upper surface of locking nut and 5 upper surface of outer support and to discharge 301 small internal diameter section upper surface of mouthful nut neat
It is flat.
The outer wall of the above-mentioned large diameter section for discharging mouthful nut 301 is designed as hexagonal structure, convenient for adjustment gasket 302 and
Fastening when welding tip 204 connects；It is simultaneously hexagon ring in the bore design of small internal diameter section, is used for small internal diameter section and locking nut
When 4 connection fastening, mouthful nut 301 is discharged from outer side using tool fixation, is convenient for tightening operation.
