The liquid level correction valve that is used for can liquid material
Technical field
The utility model relates to a kind of filling apparatus of bottled liquid material, relates in particular to the valve body structure that is used to promote the can effect on a kind of batch manufacturing equipment.
Background technology
Filling valve quantitatively has a dual mode usually to liquid material bottling: a kind of is level filling; Promptly through the height that changes muffler realize to electrolyte level quantitatively; Pouring process is simple; It is relatively more consistent that this quantivative approach takes on the wine liquid level that comes, good-looking on the sense organ, shortcoming be filling liquid influenced by bottle bigger.Relatively be applicable to the can of low and middle-grade wine.Another kind is a quantitative filling; This wherein comprises positive displacement and FL/MTR formula again; It is quantitatively more accurate to take on the wine that takes in this way, but because of generally all there is the uneven problem of bottle wall thickness in glass bottle, causes the shortcoming of volume conformability difference; Adopt the quantitative filling mode to cause liquid level to be uneven, aesthetic property is poor.Pouring process is complicated, and equipment is relatively costly, is applicable to the can of high-grade wine.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of liquid level correction valve that is used for can liquid material, and is consistent to realize the bottling electrolyte level, and realizes low cost, the effective operation of the can of liquid material.
The purpose of the utility model will be achieved through following technical scheme:
The liquid level correction valve that is used for can liquid material; Its valve body is installed in the fluid cylinder top, has the muffler that is communicated to fluid cylinder bottom filling mouth, and an end of said muffler passes filling exit and stretches into bottle; The other end of muffler is communicated to the external world from the exhausr port of valve body side; It is characterized in that: said valve body is provided with evacuation passageway and external vacuum pump in the position that is lower than exhausr port, and said evacuation passageway and exhausr port heteropleural mutually, and said valve body central authorities have rotatable switching mandrel; Switch mandrel have under the different angles with exhausr port or evacuation passageway in a duct that is connected, and an end in duct is connected with muffler and bottle intracavity.
Further, the top that said switching mandrel exposes to valve body is provided with to control and makes that switching mandrel rotates the actuating device of translation-angle.
Further, said actuating device is and the roller handle that switches the perpendicular grafting of mandrel rotating shaft.
Further, the butterfly handle of said actuating device for extending to form from switching mandrel one.
The application implementation of the utility model liquid level correction valve when carrying out can operation in enormous quantities, can keep the height conformability of liquid level in the bottle when not influencing filling speed, promote the batch aesthetics of product.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the can step scheme drawing that the utility model is implemented;
Fig. 2 is the sectional structure scheme drawing of the utility model liquid level correction valve under bottling condition;
Fig. 3 is the sectional structure scheme drawing of the utility model liquid level correction valve under liquid level correction state.
The specific embodiment
As shown in Figures 2 and 3, this is used for the liquid level correction valve 4 of can liquid material the utility model, and its valve body 41 is installed in fluid cylinder 1 top, has the muffler 11 that is communicated to fluid cylinder bottom filling mouth, and an end of this muffler 11 passes filling exit and stretches into bottle 2.Under the tradition filling valve structure, the other end of this muffler 11 directly is communicated to the external world from the exhausr port of valve body side, plays the effect that drains bottle 2 inner chamber air in the pouring process.And this only exhaust and the mode through muffler height adjustment liquid level obviously can't satisfy the conforming technological requirement of liquid level.Therefore, the utility model improves to the exhaust structure at fluid cylinder 1 top, design and in the attaching of fluid cylinder top this liquid level correction valve.From architectural feature: these liquid level correction valve 4 its valve bodies 41 be provided with evacuation passageway 43 in the position that is lower than exhausr port 42 and external vacuum pump (not shown; The vacuum pump of commercially available all size, model all is suitable for); And evacuation passageway 43 and exhausr port 42 be heteropleural mutually; These valve body 41 central authorities have rotatable switching mandrel 44; Switch mandrel have under the different angles with exhausr port or evacuation passageway in a duct that is connected 441, and an end in duct 441 is connected with muffler 11 and bottle intracavity.
In addition, the top that this switching mandrel exposes to valve body is provided with to control and makes that switching mandrel rotates the actuating device 45 of translation-angle.This actuating device 45 can be and switch the roller handle of the perpendicular grafting of mandrel 44 rotating shafts, also can be from switching the butterfly handle that mandrel 44 one extend to form, the utility model embodiment and diagram thereof preferred the former.
After this liquid level correction valve is used on the yellow rice wine bottle placer; Its principle of work and process are following: as shown in Figure 1, the step that in the whole single bottle of can cycle, finishes to can is existing maturation process step; Can be considered the F/s of the applied filling process of the utility model; And in this process, the utility model liquid level correction valve is switched to return gas channel and opens shape, carries out conventional exhaust operation.Particularly: the bottle that gets into bottle placer is promoting under the cylinder action; Through sealing valve port pad and filling valve sealing pressing; Upwards promote baffle, valve body then successively, the material pipeline is got through, the beginning can; When liquid level reaches the muffler height, stop can, the interior gas of bottle is discharged through muffler in the pouring process.
And under lifting cylinder after the can end is being left behind camming action, leave valve port, and baffle, valve body set back under action of the spring, and filling valve is in closed condition, can be considered the subordinate phase of the applied filling process of the utility model.
Switch mandrel through rotation subsequently and realize closing bottle and extraneous being communicated with; Connect evacuation passageway; Begin to revise liquid level, liquid level is through reaching the electrolyte level of a basic fixed and the certain precision of tool, again with bottle decline back bottle outlet in the bottle after revising; Finish the operation process in a can cycle, can be considered the subordinate phase of the applied filling process of the utility model.
This liquid level correction valve of the utility model is through application implementation, when carrying out can operation in enormous quantities, can when not influencing filling speed, keep the height conformability of liquid level in the bottle, promotes the batch aesthetics of product.
