Description
Technical field
The utility model relates to cylinder valve technical field, relates in particular to can be applicable to checking identification and limits the cylinder valve filled.
Background technique
Lpg filling belongs to national strict control industry, for convenience of trade management, has occurred at present utilizing identify label to strengthen the management of lpg filling.Steel cylinder installs identification label additional respectively, when filling, could inflate after the identification label only on steel cylinder have passed the identification of identifier on charge gun, having stopped the improper of other and having filled, to eliminate the potential safety hazard that the bottled gas of liquefaction brings.
In the published document of portion (liquefied gas cylinder valve CN202188214U), the magnetization closure member which employs to tilt carrys out the pod apertures of opening and closing cylinder valve.During inflation, the identifier on charge gun starts electromagnetic generator after identifying steel cylinder mark, produces electromagnetic force and drives closure member to open pod apertures inflation.The steel cylinder of None-identified then cannot start electromagnetic generator, and closure member is in closes pod apertures state and cannot inflate.But this cylinder valve, when inflating, there will be inflation pressure excessive, when inflation pressure serious offense electromagnetic force, the closure member opened can be press against and close pod apertures, causing inflating.Visible, this cylinder valve in use or existing defects, is difficult to guarantee that gas circuit is unimpeded when inflating.
In current lpg filling industry, because traditional cylinder valve does not have anti-tipping apparatus, often have staff's violation operation, fill medium in dumping bottle, this is that trade management institute is unallowed.Thus be necessary to install anti-tipping apparatus additional to cylinder valve.
Model utility content
The technical problems to be solved in the utility model is to provide a kind ofly can guarantee that when filling medium the limit that runner is unimpeded fills cylinder valve.
For solving the problems of the technologies described above adopted technological scheme: a kind of limit fills cylinder valve, include cylinder valve, it is characterized in that: in the flow passage chamber of described cylinder valve, form a pod apertures, the upper end of pod apertures is provided with one can the ferromagnetism spheroid of its upper end-hole of shutoff, upper end-hole eccentric setting in flow passage chamber of pod apertures, this side of departing from pod apertures of flow passage chamber forms the space that accommodatingly can have left the ferromagnetism spheroid of pod apertures upper end-hole, pod apertures is to should the upper-end surface in space be set as towards pod apertures downward-sloping, and the top in this space is provided with the guide plate that can swing up and down, the swinging end of guide plate is downward-sloping towards the upside of ferromagnetism spheroid, and swinging end extend to by fill medium drainage to ferromagnetism spheroid and flow passage chamber away between this chamber, side wall of containing space.
On the basis of the above, the lower end of described pod apertures is provided with one can the spheroid of its lower end mouth of shutoff, and the below of this spheroid is provided with the fixing crosspiece with to carry spheroid and lower end mouth and keep certain distance.
Adopt the beneficial effect that brings of the utility model: the pod apertures that the utility model adopts a ferromagnetism spheroid to come in opening and closing cylinder valve flow passage chamber, during inflation, after identifier on charge gun identifies steel cylinder mark, start the electromagnetic generator on charge gun, produce electromagnetic force, electromagnetic force drives ferromagnetism spheroid to leave the upper end-hole of pod apertures, rolls to this side of containing space, pod apertures is opened, thus medium can be filled in steel cylinder.Under the drainage of guide plate, fill medium ferromagnetism spheroid and flow passage chamber away from this chamber, side wall of containing space between flow, can prevent from like this filling MEDIA FLOW between ferromagnetism spheroid and this chamber, side wall of containing space, avoid the turbulent flow that produces therefrom to promote ferromagnetism spheroid to overcome electromagnetic force and to roll back the upper end-hole of pod apertures, pod apertures is blocked, causes medium to fill.After filling, withdraw charge gun, ferromagnetism spheroid loses the effect of electromagnetic force, and ferromagnetism spheroid is rolled back in pod apertures along the upper-end surface that pod apertures is downward-sloping.When filling in violation of rules and regulations, the cylinder valve not by identifying cannot start electromagnetic generator to drive ferromagnetism spheroid to leave pod apertures, and pod apertures is closed, thus cannot fill medium in steel cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model limit fills cylinder valve.
Embodiment
As shown in Figure 1, a kind of limit fills cylinder valve, includes cylinder valve 1, forms a pod apertures 12 in the flow passage chamber 11 of described cylinder valve 1, and the upper end of pod apertures 12 is provided with one can the ferromagnetism spheroid 2 of its upper end-hole of shutoff.Upper end-hole eccentric setting in flow passage chamber 11 of pod apertures 12, this side of departing from pod apertures 12 of flow passage chamber 11 forms the space 13 that accommodatingly can have left the ferromagnetism spheroid 2 of pod apertures 12 upper end-hole.Usually, containing space 13 can be located near this side of cylinder valve 1 suction port 14, and like this when charge gun is near cylinder valve, the electromagnetic force that the electromagnetic generator on charge gun produces can attract ferromagnetism spheroid 2 to leave pod apertures 12, be rolled on containing space 13, pod apertures 12 is opened.Pod apertures 12 is to should the upper-end surface in space 13 be set as towards pod apertures 12 downward-sloping, and the top in this space 13 is provided with the guide plate 3 that can swing up and down, guide plate 3 is arranged on the chamber wall of flow passage chamber 11, the swinging end of guide plate 3 is downward-sloping towards the upside of ferromagnetism spheroid 2, and swinging end extend to by fill medium drainage to ferromagnetism spheroid 2 and flow passage chamber 11 away between this chamber, side wall of containing space 13.Such guide plate 3 can keep off on ferromagnetism spheroid 2, when filling, towards the downward-sloping guide plate 3 of pod apertures 12 can by fill medium drainage to ferromagnetism spheroid 2 and flow passage chamber 11 away between this chamber, side wall of containing space 13.Were it not for the words of guide plate 3, when starting to fill, medium can flow to the surrounding of ferromagnetism spheroid 2, and can turbulent flow be produced, there will be unavoidably and promoted to overcome electromagnetic force by the electromagnetic force ferromagnetism spheroid 2 inhaled from pod apertures 12 by turbulent flow and to roll back the upper end-hole of pod apertures 12, pod apertures 12 is blocked, causes medium to fill.And MEDIA FLOW when filling can compress guide plate 3, and guide plate 3 can push down ferromagnetism spheroid 2, stop the rollback of ferromagnetism spheroid 2 further, thus it is unimpeded to guarantee to fill runner.
Steel cylinder is toppled in order to prevent staff in violation of rules and regulations, the lower end of pod apertures 12 is provided with one can the spheroid 4 of its lower end mouth of shutoff, the below of this spheroid 4 is provided with the fixing crosspiece 5 with to carry spheroid 4 and lower end mouth and keep certain distance, and crosspiece 5 is horizontal in flow passage chamber 11, and two ends are fixed on the wall of chamber.When toppling over, spheroid 4 under gravity, can be fallen on the port of pod apertures 12, lower end mouth is blocked, and can effectively prevent from toppling in violation of rules and regulations.
