The specific embodiment
As shown in Figure 1, side valve type air bubble of the present utility model, comprise storage tank 9, admission port 1, freeing pipe 11 and guiding valve, guiding valve comprises valve core of the spool valve 6 and the guiding valve cylinder body 8 that is used to control air inlet, exhaust, move between two positions of described valve core of the spool valve 6 in guiding valve cylinder body 8, a position is communicated with admission port 1 and storage tank 9 therein, and at another position connection storage tank 9 and freeing pipe 11, guiding valve cylinder body 8 one ends connect freeing pipe 11, the other end connects end cap 2, end cap 2 is provided with admission port 1, and cylinder body 8 sidewalls are provided with the opening 10 that leads to storage tank; Valve core of the spool valve 6 is the stepped shaft shape, its path part is corresponding with opening 10 positions of storage tank, its large-diameter portion divides with guiding valve cylinder body 8 suitable, be provided with retracing spring 4 between valve core of the spool valve 6 bigger diameter end ends and guiding valve cylinder end caps 2, valve core of the spool valve 6 path ends are connected vapor seal between the end of freeing pipe 11 1 ends with guiding valve cylinder body 8 at reset mode; Be provided with the flexible diaphragm 3 that is tightly connected respectively with the two end between valve core of the spool valve 6 and the guiding valve cylinder body 8; In the middle of valve core of the spool valve 6, be provided with the path that connects admission port 1 and storage tank opening 10, be provided with in the path from the check valve 5 of admission port 1 oriented storage tank 9 direction conductings.
Between described valve core of the spool valve 6 and guiding valve cylinder body 8, can be provided with cylinder sleeve 7.
Described vapor seal is formed by the tapered end and the corresponding conical valve seat of guiding valve cylinder body 8 exhaust pipe ends of valve core of the spool valve 6.
Described flexible diaphragm 3 can be crimped on guiding valve cylinder body 8 by described guiding valve cylinder end caps 2, and formation is tightly connected with guiding valve cylinder body 8; And flexible diaphragm 3 can be crimped on valve core of the spool valve 6 by platen 12, and formation is tightly connected with valve core of the spool valve 6, is provided with pores in the middle of the described platen 12; Can adopt screw to be connected between described guiding valve cylinder end caps 2 and guiding valve cylinder body 8 and described platen 12 and the valve core of the spool valve 6.
The principle of work of the utility model side valve type air bubble is as follows: pressurized air enters from admission port 1, this moment is because the effect of retracing spring 4, and the centre of flexible diaphragm 3 and valve core of the spool valve 6 have adopted the sealed attachment mode, and the outward flange of flexible diaphragm 3 and guiding valve cylinder body 8 sealed attachment, valve core of the spool valve 6 its conical surface and freeing pipe 11 conical surface face closed contacts and sealing under the guiding of guiding valve cylinder body 8 like this.The gas that enters from admission port 1 like this, the storage tank opening 10 by on check valve 5 and the guiding valve cylinder body 8 directly enters storage tank 9, when reaching specified pressure, stops air feed.At this moment admission port 1 is controlled by outer member, admission port becomes exhausr port, because gaseous tension in the storage tank 9 and admission port form pressure reduction, gas returns by former free air diffuser like this, but owing to closing of check valve 5, pressurized air promotes valve core of the spool valve 6 and flexible diaphragm 3 motions, opens until the sealing of valve core of the spool valve 6 conical surfaces and guiding valve cylinder body 8 conical surfaces.High pressure gas in the storage tank 9 produce bursting force by freeing pipe 11 abrupt releases, thereby material in the application of reality is produced explosion, and the cutting effect is arranged, and reach the effect that expect in good mediation storehouse.
