As preferably, when gland nut was connected on the gas cylinder cylinder valve, push pipe was to valve core movement, and push pipe just can back down spool, and said connecting rod is corresponding therewith with the distance that valve core chamber leaves.
As preferably, when not having filling pressure, the preload pressure of said stage clip can guarantee that spool seals under the situation of no push pipe top power.
As preferably, the angle on said connecting rod end face inclined-plane is 60 degree.
As preferably, the joint of said push pipe and spool is provided with the 2nd O RunddichtringO.
As preferably, said silently the embedding on the end face with being connected of valve body has the 3rd O RunddichtringO.
As preferably, a plurality of Baltimore grooves of said air inlet duct for opening along the tube wall of push pipe end.
As preferably, the gross area of said air inlet duct is identical with the sectional area of push pipe endoporus.
As preferably, the airspace area between said spool and valve body is greater than the sectional area of push pipe endoporus.
The beneficial effect of the utility model is: after adopting said structure, when not having filling pressure, the preload pressure of said stage clip can guarantee that spool seals under the situation of no push pipe top power; Automatically accomplished the isolated problem that fills pipe and atmosphere without manually-operable; And the sealing of adopting all is static seal, cancelled dynamic seal (packing), improved the sealing of system; Compact structure, reasonable in design.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is one of them embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the side view of push pipe among Fig. 1.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is one of them embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of automatic blocking gas charging valve comprises hollow valve body 1, is provided with the push pipe 2, spool 3 and the stage clip 4 that connect successively in the hollow structure of valve body 1, is provided with the 2nd O RunddichtringO 10 in the joint of push pipe 2 and spool 3.3 of said valve body 1 and spools leave airspace, and the area of this airspace is greater than the sectional area of push pipe 2 endoporus.Corresponding airspace place is provided with and fills interface 5 on valve body 1.The other end of said stage clip 4 is fixed in silently on 6, and this silently 6 is connected with valve body 1, silently 6 is embedding on the end face with being connected of valve body 1 the 3rd O RunddichtringO 11 is arranged.When not having filling pressure, the preload pressure of said stage clip 4 can guarantee that spool 3 seals under the situation of no push pipe 2 top power.
Said push pipe 2 extends outside the valve body 1; Be provided with connecting rod 7 in push pipe 2 outsides; 3 of connecting rod 7 and spools leave distance, and said connecting rod 7 is the inclined-plane away from the end face of valve body 1 one ends, as preferably; The angle on said connecting rod 7 end face inclined-planes is 60 degree, and on this inclined-plane, embedding has an O RunddichtringO 8.
Also be connected with the gland nut 9 that is connected with the gas cylinder cylinder valve at connecting rod 7 away from an end of valve body 1; When gland nut 9 is connected on the gas cylinder cylinder valve; Push pipe 2 is to spool 3 motions, and push pipe 2 just can back down spool 3, and 3 distances that leave of connecting rod 7 and spool are corresponding therewith.Said push pipe 2 has the air inlet duct 12 that communicates with push pipe 2 endoporus in push pipe 2 ends near spool 3 one ends; In the present embodiment; Four Baltimore grooves of said air inlet duct 12 for opening along the tube wall of push pipe end; Also can be the groove of other shapes, and the gross area of this air inlet duct 12 is identical with the sectional area of push pipe 2 endoporus.
3 O RunddichtringOs in the automatic blocking gas charging valve of the utility model all are static seals, do not have motive sealing, thereby have stopped the leakage problem when dynamic.Closing of gas charging valve is automatically, cancelled manually-operable, and the unloading and load onto with original band stop valve or not connect with the charging joint of valve be identical of gas charging valve
The working procedure of whole automatic blocking gas charging valve is following:
1, when the suction port on the valve body 1 does not have air pressure, the preload pressure of stage clip 4 to moving to left, relies on the 2nd O sealed type circle on the spool 3 that gas circuit is blocked spool 3, and atmosphere can't enter into gas tube.
2, when this automatic blocking gas charging valve and gas cylinder bottle being closed when being connected, tighten gland nut 9, rely on the impacting force of gland nut 9; Push pipe 2 is passed to spool 3; Push pipe 2 is passed spool 3 and is opened the inflation gas circuit, and gas enters into the airspace of valve body 1 and spool 3 by gas tube, and the air inlet duct 12 through push pipe 2 end faces gets into push pipes 2 inner chambers; Push pipe 2 inner chambers communicate with the gas cylinder cylinder valve, have connected the inflation loop.By the pressuring action of gland nut 9, make an O RunddichtringO 8 with the inflation conical surface tight seal of connecting rod 7 with the gas cylinder cylinder valve.Gland nut 9 firmly is connected the automatic blocking gas charging valve of the utility model on the gas cylinder cylinder valve.
3, after gas cylinder is accomplished and filled, unload loose gland nut 9, pressurized gas and stage clip 4 are passed spool 3 after acting on spool 3 simultaneously to push pipe 2, rely on the effect of the 2nd O RunddichtringO 10 that gas circuit is blocked.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
