Description

A kind of vacuum liquid filling valve

Technical field

The utility model relates to a kind of valve, is specifically related to a kind of vacuum liquid filling valve, and it is applied to the vacuum liquid filling system, as the vacuum liquid filling of lithium battery.

Background technology

The liquid-filling valve door of technology is generally the cup plunger-type structure now, and its fluid injection efficient is low, annotates plug leakage easy to wear.

Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved vacuum liquid filling valve that has, to overcome described defective of the prior art.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of rotor not fragile, seals more reliably, and work is the vacuum liquid filling valve more reliably.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of vacuum liquid filling valve, and it comprises a stator and a rotor, wherein, described stator is corrosion-resistant stator; Described rotor is corrosion-resistant rotor, and it is hollow-core construction, and it is housed in stator, and can be with respect to stator rotation; The inner surface of described stator coordinates with the outer surface liquid sealing of rotor; The stator liquid collecting cavity that described stator has at least one electrolyte inlet, at least one electrolyte liquid outlet, communicates with rotor or disconnects and the vacuum orifice that is connected with the electrolyte liquid outlet; Described rotor has the liquid in-out mouth that electrolyte inlet, electrolyte liquid outlet with stator are connected or disconnect, and has the liquid return hole that communicates or disconnect with the stator liquid collecting cavity.

Compared with prior art, the utlity model has following beneficial effect: the rotor of vacuum liquid filling valve of the present utility model is hollow-core construction, and it has the function of buffer memory fluid injection; The function that vacuumizes stator can reduce the air content in institute's fluid injection body, improves the fluid injection quality; Inlet and liquid outlet are isolated by rotor, seal more reliably, control reliably institute's fluid injection scale of construction, prevent from being annotated product not by liquid contamination, thereby more reliable.

Fig. 2 is the cutaway view at another visual angle of vacuum liquid filling valve of the present utility model.

Embodiment

see also shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of vacuum liquid filling valve, it comprises the valve stator 1 that a resistant material is made, it has a columniform inner surface 4, can certainly be the inner surface of other shape, the profile of stator 1 is cuboid basically, certainly stator 1 also can have other shape that is applicable to installing space, stator 1 is fixed on support and can moves up and down with support, have the electrolyte liquid outlet 8 that leads to battery core on it and accept electrolyte inlet 2, also has a vacuum orifice 9 that connects vacuum line on stator 1, also have one and vacuum orifice 9 on stator 1, the liquid collecting cavity 10 that the liquid return hole 11 of rotor 3 communicates.

A rotor 3 of being made by resistant material is housed in stator 1, it can be with respect to stator 1 rotation, the dead in line of the cylindrical form interior surface 4 of its rotating shaft and stator 1, rotor 3 has a cylindrical outer surface 7, certainly the also outer surface of other shapes, this outer surface 7 matches with the cylindrical form interior surface 4 of said stator 1, and its cooperate degree should reach liquid sealing, makes that electrolyte is unlikely to be spilt between two surfaces.

Have the liquid in-out mouth 5 that communicates with stator 1 inlet and liquid outlet phase place on rotor 3 on its excircle, have simultaneously the liquid return hole 11 that communicates with stator 1 liquid collecting cavity phase place, and rotor 3 is cylinder type hollow structure 6, certainly also can be the hollow-core construction of other shape.Valve feed liquor position at Fig. 1, rotor 3 is linked up liquid in-out mouth 5 and inlet 2 with respect to the residing phase place of stator 1, rotor 3 in valve rotates 90 °, arrival vacuumizes phase place, link up rotor liquid return hole 11 and stator liquid collecting cavity 10 and vacuum orifice 9, rotor 3 in valve is rotated further 180 °, arrives the phase place of valve opening position, and rotor liquid in-out mouth 5 is linked up stator liquid outlet 2 and fluid injection pin 8.

The stator outside is passed in the one or both ends of rotor, and drive unit of controlling the fluid injection valve opening and closing is connected on the outer end that rotor stretches out.

Fluid injection valve of the present utility model carries out work in the following manner: when rotor 3 is in the valve feed liquor position of Fig. 1, electrolyte enters the interior hollow-core construction 6 of rotor 3 by stator inlet 12 and rotor liquid in-out mouth 5, when rotor 3 rotates 90 °, the liquid return hole 11 of rotor 3 communicates with the liquid collecting cavity 10 of stator 1, and vacuumize by 6 fluid injection bodies of 9 pairs of hollow-core construction liquid storage cylinders of vacuum orifice this moment; Rotor 3 is rotated further 90 °, rotor liquid in-out mouth 5 and stator liquid outlet 2 positions, the residual liquid that liquid collecting cavity 10 is collected when vacuumizing is got back to hollow-core construction liquid storage cylinder 6, and this moment, valve was in opening, and electrolyte injects battery core by fluid injection pin 8 under external vacuum action.

For the utility model, must adopt corrosion-resistant material to make valve, with the useful life of guaranteeing that it is enough, should guarantee the electrolyte noresidue with the Teflon material at rotor hollow-core construction inwall.

Above embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection range of this creation.
