Specific embodiment
The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, contactless aseptic filling valve, comprising: valve body 1, is provided with valve pocket, in valve pocket in valve body 1
It is provided with valve block 3 and valve rod 4, valve pocket is separated into installation cavity 5 and the fill chamber 6 of mutual cut-off by valve block 3 from top to bottom successively.Valve
The charging aperture 2 being connected with fill chamber 6 is provided with body 1, the upper end of valve rod 4 passes through the drive mechanism phase on valve block 3 and valve body 1
Connect, seal against each other between valve rod 4 and valve block 3, the lower end of valve rod 4 is fixedly connected with valve element 7, on the outer wall of valve rod 4 bottom
It is provided with sealing gasket 8, valve body 1 bottom offers valve port 11, the inwall of valve body 1 at valve port 11 position is provided with inwardly projecting
Flange 12.It is provided with elastic bellows 9, elastic bellows 9 are sleeved on valve rod 4, the upper end of elastic bellows 9 in fill chamber 6
Sealing is fixed on the bottom of valve block 3, and the lower end of spring corrugated pipe 9 seals fixation with the outer wall of valve rod 4.In the present embodiment, charging
Mouth 2 is opened on the valve body 1 of elastic bellows 9 areas outside, and such purpose is: when the material of fill is contained within fruit grain
When, material enters the fruit grain that can be prevented effectively from material of disturbance producing in fill chamber 6 from charging aperture 2 and saves bit by bit elastic corrugated
On the undulatory outer wall of pipe 9.Drive mechanism can drive valve rod 4 band movable valve plug 7 to move straight down, until the sealing on valve rod 4
Pad 8 seals block on flange 12, so that valve port 11 is closed.Drive mechanism can also drive valve rod 4 band movable valve plug 7 vertically to
Upper motion, until the sealing gasket 8 on valve rod 4 is separated with flange 12, thus valve port 11 is opened.
The structure of the drive mechanism described in the present embodiment includes: is arranged on the cylinder 10 at valve body 1 top, the work of cylinder 10
Stopper rod 101 is fixedly connected with the upper end of valve rod 4, and the valve rod 4 in installation cavity 5 is set with spring 16, the lower side pressure gear of spring 16
On interstage sleeve 41 on being fixed on valve rod 4, the upper side pressure of spring 16 is kept off in the mounting seat 42 being fixed in installation cavity 5, described
Mounting seat 42 be sleeved on valve rod 4.After cylinder 10 ventilation, the piston rod 101 of cylinder 10 is retracted upwards and can be ordered about valve rod 4 and overcome
The elastic band movable valve plug 7 of spring 16 moves straight up, until the sealing gasket 8 on valve body 1 is separated with flange 12, thus by valve
Mouthfuls 11 open, exhaust hood 10 aerofluxuss, the spring energy of spring 16 orders about valve rod 4 band movable valve plug 7 and moves straight down, until valve rod
Sealing gasket 8 on 4 seals block on flange 12, so that valve port 11 is closed.In the present embodiment, described cylinder 10 adopts
Double stroke cylinder, the purpose using double stroke cylinder is: can more smoothly drive valve rod 4 to move.For the ease of adjusting valve port
11 flow, in the present embodiment, the outer wall of sealing gasket 8 bottom is the conical surface 81, and the circle diameter of the conical surface 81 gradually becomes from bottom to top
Greatly, formed ebb interval 13 between the conical surface 81 and flange 12, after valve port 11 is opened, the piston rod 101 of cylinder 10 continues up contracting
Resilience is ordered about valve rod 4 and is continued up so that ebb interval 13 excessively becomes larger, so that the flow of valve port 11 gradually becomes
Greatly.In addition, for the ease of installing the false cup for cleaning each part in fill chamber 6 and fill chamber 6, valve body 1 in the present embodiment
Lower end fixed cover equipped with the valve seat 17 for installing false cup, valve port 11 is located in valve seat 17, the inwall of valve seat 17 and valve body 1
Form discharge opeing gap 171, described discharge opeing gap 171 is connected with the liquid outlet 172 on valve seat 17 between outer wall.
During fill, cylinder 10 is ventilated, the piston rod 101 of cylinder 10 retract upwards order about valve rod 4 band movable valve plug 11 vertically to
Upper motion, during this, spring 16 is constantly compressed, and after the sealing gasket 8 on valve rod 4 is separated with flange 12, valve port 11 is opened,
At this moment enter to material in fill chamber 6 through charging aperture 2 and lead, in valve element 7, the bottle flowing downwardly into required fill from valve port 11
Interior.The distance that valve rod 4 moves upwards is bigger, and ebb interval 13 excessively is also bigger, and the flow of valve port 11 is also bigger, and this makes filling speed
Regulation very convenient, the controllability of material-filling and motility are also greatly enhanced.In actual pouring process, can basis
Different material selects different filling speeds.Generally, in fill sensitive materials easy to foaming, can be by the material in valve port 11
Flow velocity is suitably turned down, prevents material in bottle from bubbling, thus improving filling quality.In fill material not easy to foaming, can be by
In valve port 11, material flow suitably tunes up, so as to greatly improve fill efficiency.After fill finishes, cylinder 10 aerofluxuss, spring 16
Elastic force order about valve rod 4 band movable valve plug 7 move straight down, until valve rod 4 on sealing gasket 8 sealing block on flange 12,
So valve port 11 is closed.Due to being provided with one section of elastic bellows 9, the upper end of elastic bellows 9 and valve block in fill chamber 6
3 bottom seals against each other, the outer wall of the lower end of elastic bellows 9 and valve rod 4 seals against each other, and the setting of elastic bellows 9 makes
That section of valve rod 4 being contacted with installation cavity 5 and valve block 3 is isolated with fill chamber 6 all the time, so can effectively prevent valve rod 4
The microorganisms such as the antibacterial in installation cavity 5 are brought in fill chamber 6, thus really realizing sterile filling, greatly reducing product and existing
The risk that shelf life goes bad.Contactless aseptic filling valve of the present invention is applied to various beverages fill, is particularly suited for
Beverage filling containing fruit grain, during fill contains the beverage of fruit grain, with the up and down motion of valve rod 4, elastic bellows 9 meeting
Be stretched or compressed, the stretching of elastic bellows 9 or compression, can not only prevent fruit grain block on corrugated outer wall moreover it is possible to
Disturbance is produced to the material in fill chamber 6, effectively prevents fruit grain block in fill intracavity, thus assisting raising fill efficiency.
