be arranged in frame 1, the piston rod of the second cylinder 71 extends downwards and corresponding liquid level correction valve 5 can be driven to move downward, when drain sleeve 53 and the second pouring pipe 57 stretch in corresponding container 6, and the second orienting sleeve 54 sealing shroud gear is after the oral area of corresponding container 6, the piston rod of the second cylinder 71 continues to extend the elastic force that the second valve body 51 can be driven to overcome the second spring 10 downwards and moves downward along the second pouring pipe 57, make the second liquid filling pore 571 and second fill with sap cavity 55 to be connected until open the second upper sealing mechanism, namely liquid level correction valve 5 is made to be in valve opening state.The piston rod of the second cylinder 71 is upwards retracted and can be driven the second valve body 51 upward movement, second valve body 51 moves to the direction away from the second valve seat 52, cut off until the second liquid filling pore 571 and second fill with again to seal between sap cavity 55 by the second upper sealing mechanism, not only make liquid level correction valve 5 but also be in close valve state, the piston rod of the second cylinder 71 is upwards retracted and can be driven liquid level correction valve 5 upward movement subsequently, until the second pouring pipe 57, drain sleeve 53 and the second orienting sleeve 54 are separated with corresponding container 6 and return back to original position respectively.
The second described upper sealing mechanism comprises: the second baffle 572 outer wall on the second pouring pipe 57 top being provided with ring-type, ring-type is provided with bottom second baffle 572 and between the outer wall of the second pouring pipe 57, the second mounting groove be inwardly recessed, second top seal circle 573 is installed in second mounting groove, the hole wall and second at the second valve hole 56 top fills with the second convex shoulder 11 forming ring-type between the inwall bottom sap cavity 55, second spring 10 can order about the second pouring pipe 57 relative second valve body 51 in the second valve body 51 and move downward, until the second top seal circle 573 seals block on the second convex shoulder 11, second liquid filling pore 571 and second is filled with to seal between sap cavity 55 to cut off, namely liquid level correction valve 5 is made to be in close valve state.The structure of the second upper sealing mechanism is simple, good sealing effect.The second described hole wall sealing mechanism comprises: the second sealed groove 561 that the inwall of the second valve hole 56 is provided with ring-type, that be inwardly recessed, be provided with the second hole wall seal ring 562, second hole wall seal ring 562 in second sealed groove 561 can make to be formed between the outer wall of the second pouring pipe 57 below the second liquid filling pore 571 and the hole wall of the second valve hole 56 to seal.
The principle of work of liquid level correction valve 5 is as follows: time filling, the piston rod of the second cylinder 71 extends downwards, corresponding liquid level correction valve 5 is driven to move downward, when the lower end of the second pouring pipe 57 and drain sleeve 53 stretches in corresponding container 6, and packing seal 541 sealing shroud of the second orienting sleeve 54 gear is after the oral area of corresponding container 6, the piston rod of the second cylinder 71 continues to extend downwards, thus drive the second valve body 51 to compress the second spring 10 to move along the second pouring pipe 57 near the direction of the second valve seat 52, until the second liquid filling pore 571 enters in the second filling sap cavity 55 and makes the second liquid filling pore 571 and second fill with sap cavity 55 to be connected, namely liquid level correction valve 5 is made to be in valve opening state, such liquid constantly enters to the second filling sap cavity 55 from the second feed tube 9, second liquid of filling with in sap cavity 55 constantly enters in corresponding container 6 from the second pouring pipe 57 under gravity, thus carry out filling to container 6.Time filling, air in container 6 is constantly discharged rapidly through exhaust tube 59 by drain sleeve 53 from counter flow pipe 58, when the liquid level of the container 6 of correspondence is to the return port 531 of drain sleeve 53, the liquid in container will be discharged through drain sleeve 53 by return port 531 from counter flow pipe 58.After filling, the piston rod of the second cylinder 71 is upwards retracted and is driven the second valve body 51 upward movement of corresponding liquid level correction valve 5, move in the direction that second valve body 51 is rapidly to away from the second valve seat 52, until the second top seal circle 573 seals block on the second convex shoulder 11, namely liquid level correction valve 5 is made to close valve and stop filling, the piston rod of the second cylinder 71 continues upwards to retract until drive whole liquid level correction valve 5 upward movement subsequently, until the second pouring pipe 57, drain sleeve 53 and the second orienting sleeve 54 are separated with corresponding container respectively, and return back to original position, to dodge out container 6, allow and complete filling container 6 and move to next station.The structure of above-mentioned liquid level correction valve 5 is also very simple, and cost is also very low.
Linear filling technique is as follows: first suppose only to arrange a Quick-filling station 2 in linear filling device.During work, a batch containers 6 identical with quick filling valve 4 quantity in a Quick-filling station 2 enter simultaneously carry out in Quick-filling station 2 filling, and then enter simultaneously carry out in liquid level correction station 3 filling.The filling pressure of each quick filling valve 4 in Quick-filling station 2 controls at 0.01MP ~ 0.15MP, and the filling amount that each quick filling valve 4 completes is 70% ~ 80% of the total filling amount of corresponding container 6, and without backflow.The container 6 completing 70% ~ 80% filling amount is fed simultaneously in liquid level correction station 3 again, all liquid level correction valves 5 in liquid level correction station 3 carry out filling to the container 6 completing 70% ~ 80% filling amount of correspondence simultaneously, and the filling amount that each liquid level correction valve 5 completes is 20% ~ 30% of the total filling amount of a container 6 of correspondence.Because liquid level correction valve 5 need complete 20% ~ 30% of total filling amount, therefore liquid level repair dress valve 5 filling time the liquid backflow amount that produces also greatly reduce, thus greatly reduce the energy consumption of whole pouring process.In actual pouring process, in linear filling device, multiple Quick-filling station 2 can be set gradually according to actual needs.Such as arrange three Quick-filling stations 2, the filling amount of total that container 6 completes after three Quick-filling stations 2 are filling is 70% ~ 80% of the total filling amount of container 6.Multiple Quick-filling station 2 is rationally set, filling efficiency can be improved further.
Following statistics was done by my company: adopt above-mentioned linear filling technique and rotary filling technique to complete the filling of the GPB of 2000 five gallon bottles respectively simultaneously, in linear filling technique, the quantity of reflux of the GPB of each five gallon bottle is at 0.5L ~ 1L, and total quantity of reflux is at 1000L ~ 2000L; In rotary filling technique, the quantity of reflux of the GPB of each five gallon bottle is at 5L ~ 8L, and total quantity of reflux is at 10000L ~ 16000L.
Adopt linear filling technique and rotary filling technique to complete the filling of the GPB of 2000 three gallons respectively, when linear filling device is filling, the quantity of reflux of GPB of each three gallons is at 0.3L ~ 1.2L, and total quantity of reflux is at 600L ~ 2400L simultaneously; When rotary filling machine is filling, the quantity of reflux of GPB of each three gallons is at 3L ~ 4.8L, and total quantity of reflux is at 6000L ~ 9600L.
Above data obviously can find out that in linear filling technique of the present invention, quantity of reflux is far smaller than the quantity of reflux of rotary filling technique, therefore linear filling technique of the present invention is adopted to carry out filling, its filling efficiency improves greatly, filling energy consumption reduces greatly, and filling cost reduces greatly.
