Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
The internal thread of air inlet end cap 2 and the external screw thread of air inlet pipe 11 screw, and screw-driven drives exhaust when thread cap 7 screws
Pipe 9 moves axially under the guiding of inwall feather key 12, and then inwall feather key 12 drives conical plug 10 axially on blast pipe 9
Motion, formation extruding reaches sealing work between the port of rubber stopper 5 and taper tube chamber 103 under the spring-force driven dual of volute spring 8
With.Conical cavity 103 can reduce gap with tapered, increase sealability.There is internal thread in end cap 4, store up the outside cylinder of pressure chamber 101
Wall has external screw thread, and rubber stopper 5 is tightened in storage pressure chamber 101 by end cap 4.There are internal thread, sealing gasket first 3 in air inlet end cap 2
Be positioned in air inlet end cap 2 in cylinder, by air inlet end cap 2 and the thread seal of air inlet pipe 11, and using compress sealing gasket first 3 come
Realize that air inlet end cap 2 seals with the phase of air inlet pipe 11.Positioning baffle 23 is only screwed in air inlet pipe 11 when installing.
Ladder pipe 13 is screwed using screw thread with blast pipe 9 and compresses sealing gasket second 14 to complete to seal, and commutate core 18 and ladder
Pipe 13 is sealed using sealing ring first 15, has a through hole in the core 18 that commutates, its through hole is provided with the porous abutting end of cylinder 19
One sealing ring fourth 24.When rotated, sealing ring fourth 24 can be slided in detent 27, and with the bottom of detent 27 and interior
Wall is realized and is slidingly sealed, so as to realize the conversion between hole.When reaching through hole, spring standoff tab 25 can be pressed into porous cylinder
In 19 detent 27 so that the through hole that the through hole of commutation core 18 can be accurately with porous cylinder 19 communicates, and now, the mouth of pipe is close
Packing 17 has covered other through holes, prevents pressurising part from being released full of rear air pressure, and ferrule pad 17 can follow commutation core 18 same
Step rotates, to complete the smooth conversion direction when rotating.
Operation principle of the present utility model：
During inflation, air pressure resists cylindrical spring 6 and opens the top of rubber stopper 5, and gases at high pressure enter inlet plenum 102, inlet plenum 102
It is connected with exhaust chamber 104, gas is discharged by the end port of exhaust chamber 104 and completes pressurising.Meanwhile gases at high pressure during inflation pass through
Aperture on the edge of rubber stopper 5, gases at high pressure are stored in storage pressure chamber 101, store up the pressure of the pressure and valve inner inside pressure chamber 101
Power is equal.When stopping charger moment, the pressure of air inlet mouth of pipe 1 is zero, and now stores up the pressure in pressure chamber 101 at a flash
Between still keep high pressure conditions, therefore with the pressure initiation pressure difference outside air inlet mouth of pipe 1, under the influence of air pressure rubber stopper 5
It is pressed in air inlet mouth of pipe 1, diastole resets cylindrical spring 6 under spring force, can be sealed using the method for pressure difference with moment
Close air inlet mouth of pipe 1 and play unidirectional effect.
Pressure release, when gases at high pressure are in exhaust chamber 104, due to conical plug 10 by exhaust chamber 104 and it is extraneous separate, institute
So that when inner gas pressure reaches setting value, high pressure air pressure can resist volute spring 8 and hold the top of conical plug 10, make conical plug 10 and cone
Gap is produced between the port of shape chamber 103, gas is discharged by the through hole on positioning baffle 23.Air pressure is less than in exhaust chamber 104
After setting air pressure, conical plug 10 compresses the inwall of the port of conical cavity 103 in the presence of volute spring 8, re-forms sealing.
Thread cap 7 is only subjected to rotate counterclockwise in set pressure or turned clockwise, when in rotation thread cap 7
When, the internal thread of thread cap 7 forms worm drive with the external screw thread of blast pipe 9, and thread cap 7 due to there is positioning baffle 23 in the axial direction
Block, so when rotated, thread cap 7 moves axially in axially motionless, blast pipe 9；Exhaust chamber 104 is in internal surface of column has
Wall feather key 12, it is engaged with the outer wall feather key 26 of air inlet pipe 11, because inwall feather key 12 is raised, when thread cap 7 rotates
During pretension volute spring 8, the inwall feather key 12 of blast pipe 9 can promote the pretension volute spring 8 of conical plug 10, so as to realize fixation
Pressure value.
Pressure regulation is commutated, and gas is entered by exhaust chamber 104 in the through hole of ladder pipe 13, has one to lead on commutation core 18
Hole is rotated by the core 18 that commutates, and after gases at high pressure enter porous tubing string 19, is discharged gas by pressurising bend pipe 20, is so existed
During to multiple different pressures part pressurisings, part will be only filled in advance and will be connected with pressurising bend pipe 20 of the present utility model, then can be led to
Cross and rotate commutation core 18, thread cap 7 and complete pressurising between different parts, only need clamped one time, facilitate operation.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
