Description
Technical field
The present invention relates to mechanical equipment more particularly to a kind of double quantitative mechanisms of liquid and the double quantitative approach of liquid.
Background technique
In the manufacturing process of beverage, health care product and medicine, need to pack the content of liquid as requested, it is existing
Metering outfit is measuring cup in packaging process, and setting needs to measure corresponding content with the corresponding graduation mark of content is corresponded on measuring cup
Liquid when being packed, then by liquid pour into measuring cup and with requiring the corresponding graduation mark of content concordant, existing judgement liquid
Body is to be observed by eyes with the whether concordant method of graduation mark, and there are errors in reading for the method observed by eyes
Big deficiency；In addition the amount of liquid poured into is difficult to just meet the requirements, and it is few that not to be be exactly more, and it is more when take out it is extra
(to be sucked out again and again by suction pipe) cumbersome when liquid.
Summary of the invention
The convenient double quantitative mechanisms of liquid, solve logical when can measure the metering of two kinds of contents the present invention provides one kind
Eyes observation liquid level is crossed to carry out measurement error existing for the First Astronautic Research Institute for Measurement and Test greatly with the mode whether corresponding graduation mark is aligned and take out liquid
When trouble problem.
The above technical problem is solved through the following technical scheme: a kind of double quantitative mechanisms of liquid, which is characterized in that packet
Include liquid storage cylinder and liquid quantitative structure, the liquid storage cylinder includes the major diameter section set gradually from the top down, central diameter section and small
Diameter section forms the first capacity and compares step, forms the between the central diameter section and path section between the major diameter section and central diameter section
Two capacity compare step, and the liquid quantitative structure includes the overall diameter extraction raffinate storage equal with the interior diameter of the central diameter section
Cylinder can seal the positioning ring being set in outside extraction raffinate storage cylinder and drive the extraction raffinate storage cylinder lifting air of extraction raffinate storage cylinder lifting
Cylinder, the overall diameter of the positioning ring is equal with the interior diameter of the major diameter section, is removably connected in the extraction raffinate storage cylinder just
Property structure isolation emit, the isolation emits and can be sealed connected together to form sealing between the bottom wall of the extraction raffinate storage cylinder
Room, the lower surface of the bottom wall of the extraction raffinate storage cylinder are equipped with the capillary of several perforations sealing room, the extraction raffinate storage
The outer surface of the bottom wall of cylinder is flat.The technical program is filled envelope by will exceed space required for liquid in liquid storage cylinder
It closes to judge whether amount of liquid meets the requirements, there is no error in reading therefore accuracy is good, extra liquid is taken out in liquid storage cylinder
Fast and easy when body.It can complete the metering of two kinds of contents.
Preferably, being additionally provided with magnet holding ring in the extraction raffinate storage cylinder, the periphery emitted of being isolated is equipped with elasticity
Sealing lip, the bottom wall of the extraction raffinate storage cylinder be equipped with the magnet holding ring cooperate and clamp the elastic packing lip and
So that elastic packing lip seal is connected to the first annular ferromagnet on the bottom wall of the extraction raffinate storage cylinder.When can be improved sealing
Reliability, when extra liquid enters extraction raffinate storage cylinder in liquid storage cylinder can automatically by isolation emit jack-up and to be isolated
Emit lose sealing function then again can be on automatic-sealed without interfering liquid outflow, discharge to reach after requirement.
Preferably, the circumferential surface of the extraction raffinate storage cylinder, which is equipped with magnet, adsorbs ring, the positioning ring is equipped with described
Magnet absorption ring cooperates and makes positioning ring in company with the second annular magnet body of extraction raffinate storage cylinder removal liquid storage cylinder.When remaining
Liquid storage cylinder proposes that positioning ring can take out together in company with liquid storage cylinder when liquid storage cylinder.
Preferably, the cylinder body upper sleeve gasket of the extraction raffinate storage cylinder lifting cylinder is equipped with outer cylinder, the outer cylinder and extraction raffinate
Annular gas receiver is formed between the cylinder body of storage cylinder lifting cylinder, sealing slidably connects vertically side in the annular inflatable cylinder
The elevating mechanism gone up and down to mobile annular piston and driving annular piston, the annular piston divide the annular gas receiver
For seal chamber and open cavity, the inner peripheral surface of the positioning ring is equipped with the circular pit circumferentially extended along positioning ring, the annular
The open end of pit is sealedly connected with rubber sealing boot and circular pit is made to form annular air storage chamber, and the annular air storage chamber is logical
It crosses flexible pipe to be connected to the seal chamber, positioning ring drives the gas in the seal chamber to flow into the annular by elevating mechanism
It goes to heave rubber sealing boot and seal against on the extraction raffinate storage cylinder and be tightly connected with extraction raffinate storage cylinder in air storage chamber
Together.When needing liquid level concordant with the first capacity comparison step, then make extraction raffinate storage cylinder to annular air storage chamber inflation
And positioning ring is sealed and prevents liquid from can flow out between extraction raffinate storage cylinder and positioning ring and influence the accurate of metering
Property.When needing liquid level concordant with the second capacity comparison step, then deflates to annular air storage chamber inflation and make extraction raffinate storage cylinder
With positioning ring be not sealed at together and can easily equal motion so that positioning cup can be equivalent to positioning ring move down and
Gear is connected to the second capacity and compares on step.The cylinder body of lifting cylinder can also serve as the barrel of annular gas receiver, and structural compactness is good.
Gas can be recycled, recorded when first is effectively sealed the position where annular piston, then it is subsequent carry out it is close
It only needs for annular piston to be moved to the position when envelope, therefore can easily know whether to have carried out effective sealing.If
It is inflated by air pump, needing to design air gauge can know whether to have carried out reliable sealing, and the technical program can then be save
Air gauge is also able to know whether to have carried out reliable sealing.Noise when air pump tank gas is big, and when the technical program progress tank gas
Noise it is small, therefore the feature of environmental protection is good.
