The second installation that ring-type is provided between the outer wall of plate 572, the bottom of second baffle 572 and the second pouring pipe 57, being inwardly recessed
Groove, is provided with the second top sealing ring 573, the hole wall at the top of the second valve hole 56 and the second liquid filling chamber 55 in the second mounting groove
The second convex shoulder 11 of ring-type is formed between the inwall of bottom, second spring 10 can order about the second pouring pipe 57 in the second valve body 51
Moved downward with respect to the second valve body 51, until the second top sealing ring 573 seal block on the second convex shoulder 11 so that second fill
Cut-off is sealed between the liquid filling chamber 55 of fluid apertures 571 and second, causes that liquid level correction valve 5 is in close valve state.Second top seal
The simple structure of mechanism, good sealing effect.The second described hole wall sealing mechanism includes：Set on the inwall of the second valve hole 56
The second sealed groove 561 being equipped with ring-type, being inwardly recessed, the second hole wall sealing ring is provided with the second sealed groove 561
562, the second hole wall sealing ring 562 can cause that the outer wall and the second valve body of the second pouring pipe 57 of the lower section of the second liquid filling pore 571 are logical
Sealing is formed between the hole wall in hole 56.
The operation principle of liquid level correction valve 5 is as follows：When filling, the piston rod of the second cylinder 71 extends downwards, drives correspondence
Liquid level correction valve 5 move downward, stretch in corresponding container 6 when the lower end of the second pouring pipe 57 and drain sleeve 53 and
After the oral area of correspondence container 6, the piston rod of the second cylinder 71 continues downward to the sealing shroud of sealing gasket 541 gear of the second fairlead 54
Elongation, so as to drive the second valve body 51 to compress second spring 10 be transported near the direction of the second valve seat 52 along the second pouring pipe 57
It is dynamic, until the second liquid filling pore 571 into causing the second liquid filling pore 571 to be connected with the second liquid filling chamber 55 in the second liquid filling chamber 55,
I.e. so that liquid level correction valve 5 is in valve opening state, during such liquid constantly enters to the second liquid filling chamber 55 from the second feed tube 9,
Liquid under gravity in the second liquid filling chamber 55 is constantly entered in corresponding container 6 from the second pouring pipe 57, so that right
Container 6 carries out filling.When filling, the air in container 6 is constantly fast from return duct 58 through discharge pipe 59 by drain sleeve 53
Speed discharge, when corresponding container 6 liquid level to drain sleeve 53 return port 531 when, liquid in container will be by backflow
Discharged from return duct 58 through drain sleeve 53 in hole 531.It is filling finish after, the drive of retracting upwards of the piston rod of the second cylinder 71 is right
Second motion upwards of valve body 51 of the liquid level correction valve 5 answered, the second valve body 51 is moved rapidly to the direction away from the second valve seat 52,
Until the second top sealing ring 573 seal block on the second convex shoulder 11, i.e. cause liquid level correction valve 5 pass valve and stop it is filling,
The piston rod of subsequent second cylinder 71 continues up retraction until driving whole liquid level correction valve 5 to move upwards, until second fills
Liquid pipe 57, the fairlead 54 of drain sleeve 53 and second are separated with corresponding container and return back to original position respectively, to avoid out
Container 6, allows the container 6 being successfully filled to be moved to next station.The structure of above-mentioned liquid level correction valve 5 also very simple,
Cost is also very low.
Linear filling technique is as follows：Assume initially that one Quick-filling station 2 of setting in linear filling device.Work
When making, Quick-filling work is entered simultaneously with the batch containers 6 of 4 quantity identical of quick filling valve one in a Quick-filling station 2
Carried out in position 2 it is filling, it is then simultaneously filling into carrying out in liquid level amendment station 3 again.Each in Quick-filling station 2 is quick
In 0.01MP~0.15MP, the filling amount that each quick filling valve 4 is completed is corresponding container for the filling pressure control of filling valve 4
The 70%~80% of 6 total filling amount, and without backflow.The container 6 for completing 70%~80% filling amount is fed simultaneously to liquid level again
In amendment station 3, to have completed 70%~80% filling to corresponding simultaneously for all liquid level correction valves 5 in liquid level amendment station 3
The container 6 of amount carry out it is filling, each liquid level correction valve 5 complete filling amount be the total filling amount of a corresponding container 6 20%~
30%.Because liquid level correction valve 5 need to complete the 20%~30% of total filling amount, thus liquid level repair dress valve 5 it is filling when the liquid that produces
Capacity of returns also greatly reduces, so as to greatly reduce the energy consumption of whole pouring process.In actual pouring process, linear filling
Multiple Quick-filling stations 2 can be according to actual needs set gradually in device.Three Quick-filling stations 2 are for example set, are held
Total filling amount that device 6 is completed through three Quick-filling stations 2 after filling is the 70%~80% of total filling amount of container 6.Rationally
Multiple Quick-filling stations 2 are set, filling efficiency can be further improved.
Following statistics was done by my company：Above-mentioned linear filling technique is respectively adopted to be completed simultaneously with rotary filling technique
2000 GPBs of five gallon bottle it is filling, in linear filling technique the capacity of returns of the GPB of each five gallon bottle 0.5L~
1L, total capacity of returns is in 1000L~2000L；In rotary filling technique the capacity of returns of the GPB of each five gallon bottle 5L~
8L, total capacity of returns is in 10000L~16000L.
Linear filling technique is respectively adopted with rotary filling technique while completing 2000 three gallons of GPB
Filling, in 0.3L~1.2L, total capacity of returns exists the capacity of returns of each three gallons of GPB when linear filling device is filling
600L~2400L；The capacity of returns of each three gallons of GPB is in 3L~4.8L, total capacity of returns when rotary filling machine is filling
In 6000L~9600L.
Data above is this it appears that capacity of returns is far smaller than rotary in linear filling technique of the present invention
The capacity of returns of filling process, therefore carried out using linear filling technique of the present invention filling, its filling efficiency is carried significantly
Height, filling energy consumption is greatly reduced, and filling cost is substantially reduced.
