Description
Technical field
The present invention relates to the filling valve of a kind of liquid filling device, be specifically related to a kind of three grades of filling valves with suction function of thinking highly of oneself.
Background technology
The most at home and abroad in the liquid quantitative filling equipment of packaging field, the structure of filling valve is to determine filling quality, filling all the time
Dress precision and the important step of filling speed.In order to meet the double requirements of filling speed and filling accuracy, mostly use large and small
The double speed fill pattern of flow switch, big flow ensures filling speed, and low discharge ensures filling accuracy；And low discharge all leans on
Adjust what the gap δ size between spool and valve port was formed.The defect of existing filling valve is:
1, there is contradiction between filling speed and filling accuracy, large and small flow mutually restricts: big flow latus rectum is π D2/4；
Low discharge latus rectum is π D δ, and in order to ensure filling speed, the generally latus rectum by increase valve port realizes, and in order to ensure fill essence
Degree, ensures that the latus rectum of low discharge is constant again, then can only reduce the gap δ of spool and valve port, can produce when gap δ is the least
Raw a lot of problems: first, in each action, the minor variations of gap δ all can have influence on filling accuracy；Second, stream can be strengthened
Pressure during cut-to-measure is changed changes, and produces lateral splash；3rd, if filling apparatus has multiple filling valve, spool and valve port
Gap cannot be adjusted to completely the same.The filling accuracy of the most whole filling apparatus it is difficult to ensure that, make the system can not stable operation.
2, material dripping problems after closing valve: around spool and valve port, the liquid material of residual finally agglomerates to spool lower end water clock, thing
Gob can affect filling accuracy in draining to pail pack；Water clock can pollute pail pack outside pail pack, and this is that filling liquid field is difficult to
The problem solved, traditional solution is to add receiver or negative suction device.First, increase receiver and can collect major part
The liquid material of water clock, but can not avoid completely, and the action such as the stretching out of receiver, retraction can largely effect on filling speed,
Additionally rotate on Weighing type bulking machine at some, owing to the restriction of structure space cannot install receiver additional；Second, increase negative suction and fill
Dripping problems can be solved while ensureing filling speed although putting, but current negative suction device is all to set one at filling valve center
Through hole, in filling valve exterior design a set of negative pressure-pumping system, after closing valve, the residual liquid material of fill head siphons away, and this mode makes
Filling valve structure is complicated, and the material of negative sucking-off will also result in waste.
Summary of the invention
It is an object of the invention to provide three grades of filling valves of a kind of conceited suction, this filling valve can solve the problem that small-large flow mutually restrict,

Detailed description of the invention
With detailed description of the invention, technical scheme is described in further details below in conjunction with the accompanying drawings.Obviously, described
Embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on embodiments of the invention, this area
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into claimed
Scope.
As it is shown in figure 1, filling valve and cylinder saddle are fixedly arranged on filling machine, outer valve cylindrical topmost is fluted,
The inner side of cylinder saddle is stuck in groove inner support filling valve, and outside is screwed on filling machine, and double stroke cylinder is solid with screw
Being scheduled on cylinder saddle, cylinder rod is connected with valve stem tip by floating junction, and floating junction can reduce the alignment of the two,
Cylinder rod can drive valve rod oscilaltion and valve opening, pass valve.
In filling valve, three back-moving springs make filling valve complete valve opening, close valve and negative suction task, the compression stress of outer valve back-moving spring and
Rigidity is much larger than internal valve back-moving spring and negative suction back-moving spring, it is ensured that when cylinder is died, outer valve back-moving spring be enough to overcome two other
The compression stress of spring and make filling valve be in sealing state.
There is flange the upper end of fairlead, is used for positioning internal valve back-moving spring；Its middle ring surface has multiple through hole, liquid in valve
Body circulates；Its lower end is fluted, is used for positioning internal valve cavity.
Multiple through hole, the liquid in outer valve pocket and the fluid communication in internal valve cavity is had on the outer wall of internal valve cavity.
The operation principle of three grades of filling valves of a kind of conceited suction that the present invention provides is as follows: material enters from the charging aperture of upper valve body and fills
Dress valve, when pail pack put in place carry out fill time, double stroke cylinder whole process returns, and band ovable valve stem rises to highest order and carries out big flow
Fill.As shown in Figure 2.During valve opening, valve rod drives negative suction valve and internal valve to rise, and bears and inhales valve back-moving spring and internal valve back-moving spring
Being completely in stretching, extension reset state, the inside and outside sealing cone of interior valve port all departs from, and internal valve, outer valve are in open mode entirely；
And valve opening moment, the negative stretching, extension inhaling valve back-moving spring resets and makes negative soup stick move down in negative suction cavity, by suitable for the liquid of negative suction intracavity
The pore negative soup stick center is discharged, and flows out from discharging opening together with material stream；When fill reaches the 95% of whole fill amount,
Close big flow and enter low discharge bottling condition.As shown in Figure 3.Double stroke cylinder stroke is to middle position, and band ovable valve stem declines, interior
Valve port enters the discharging opening of lower valve body, its male cone (strobilus masculinus) and the inner conical surface gluing, sealing of lower valve body, closes big flow, and material can only
Low discharge outlet from interior valve port center is discharged；Valve is closed when low discharge fill reaches fill set amount.As shown in Figure 4, Figure 5.
Double stroke cylinder continues to stretch out, and band ovable valve stem declines, and outer valve back-moving spring stretches and resets, and internal valve back-moving spring compresses, internal negative
Suction valve declines, and negative soup stick enters the discharging opening of interior valve port, its male cone (strobilus masculinus) and the inner conical surface gluing, sealing of interior valve port, is now in
Negative pick up a little, as shown in Figure 4 when closing valve；Valve rod continues to decline, and negative valve back-moving spring of inhaling compresses, and negative soup stick is at negative suction cavity
Moving on inside, negative cavity volume of inhaling increases, and the residual liquid of the fill valve head pore along negative soup stick center is inhaled by the negative pressure of intracavity
Enter to bear suction chamber.Negative suction terminal when closing valve it is in, as shown in Figure 5 when double stroke cylinder whole process is stretched out.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.To these
The multiple amendment of embodiment is apparent from for the patented technology personnel of this area, and generic principles defined herein can
With without departing from the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to herein
These shown embodiments, and it is to fit to the widest range consistent with principles disclosed herein and features of novelty.
