The aseptic filling valve of this type of band barrier film is not suitable for the fill operations of the material of thickness.Because need when the material of filling thickness to press to material, so that material can flow in delivery duct, so be subject to the pressure come from material transmission at aseptic filling valve, the service life of pressure environment lower diaphragm plate extremely short and barrier film cannot meet the needs of normal fill operations.
Summary of the invention
The technical problem to be solved in the present invention is the problem of valve inner dead angle area, provides the aseptic filling valve that a kind of valve inner is bright and clean, smooth.
Another technical purpose of the present invention is the place be placed in by the connection location of blocked shot and other power transmission member beyond aseptic area, eliminates tolerance clearance between blocked shot and other power transmission member to the adverse effect of aseptic area.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: this aseptic filling valve comprises valve body, blocked shot, Connection Block, adapter sleeve, double stroke cylinder, the cylinder body of described double stroke cylinder is fixedly connected with one end of adapter sleeve, the other end of described adapter sleeve is connected with one end liquid sealing of Connection Block, one end of described Connection Block is connected with one end liquid sealing of valve body, described blocked shot is positioned at valve body, Connection Block, in adapter sleeve, the piston rod of described double stroke cylinder is positioned at adapter sleeve and is fixedly connected with one end of blocked shot, described blocked shot is connected by sealing shroud liquid sealing with between adapter sleeve, the described blocked shot other end is provided with sealing surface I, described valve interior surface is provided with sealing surface II, described blocked shot is only connected with valve body in sealing surface I position and is only connected with sealing surface II liquid sealing, described Connection Block side is provided with inlet point, described Connection Block is provided with steam cavity between inlet point and this end of Connection Block and adapter sleeve, described blocked shot is all connected with Connection Block vapor seal at the two ends of steam cavity, described Connection Block is provided with the induction opening and air gate that are communicated with steam cavity, described inlet point is communicated with valve inner, described adapter sleeve is inner to be completely cut off with valve inner.
Adapter sleeve, Connection Block, valve body link together, and three is in the same center line.Adapter sleeve is connected with blocked shot liquid sealing by sealing shroud, sealing shroud not only plays sealing function, also play guiding restriction, make sealing shroud maintain blocked shot in valve body, be in vertical location status, the line of centers of line of centers and blocked shot that this vertical location status is valve body overlaps.Aseptic area and the non sterile area of valve inner are isolated by steam cavity, and steam cavity itself is in germ-free condition, it also carries out disinfecting action to the blocked shot position be in steam cavity.Only playing the location contacts of on-off action between blocked shot and valve body, between other position, be in the position relationship of separation, making the inside face of blocked shot surface and valve body bright and clean and smooth, there is no the structure of recessed joint and finedraw.Aseptic area is distributed on valve body and Connection Block, between blocked shot with Connection Block vapor seal be connected after aseptic area have to be in communication with the outside at the inlet point of valve body and discharge outlet, bearing of trend along its line of centers during blocked shot work does straight reciprocating motion, blocked shot motion all can pass through steam cavity, forms the environment being used for sterilizing and can carry out sterilization operation to the blocked shot position stretching into aseptic area in steam cavity.The effect of Connection Block is not only to connect valve body and adapter sleeve, is also introduced in valve body by material conveying passage by three-port structure.The piston rod of blocked shot and double stroke cylinder forms annexation in adapter sleeve, therefore, the connection location of blocked shot and power transmission member is positioned at outside aseptic area, certainly will improve the cleaning performance of valve inner like this, has vital function to maintenance valve inner germ-free condition.
Form the environment being used for sterilizing and can adopt chemical reagent sterilizing, ray sterilizing, hot air sterilization, moist heat sterilization, filtration sterilization etc.Because steam cavity is separate chamber, the sterilization functions of vapor chamber is only for blocked shot surface, and blocked shot contacts with material, therefore can adopt wet heat sterilization method, such as passes into saturated steam, boiling water or flowing steam.No matter be saturated steam, boiling water or flowing steam, the pressure of three all can be greater than ambient atmosphere pressure, and be in the higher state of temperature, compare the state that ambient atmosphere environment three is in High Temperature High Pressure, saturated steam, boiling water or flowing steam flow through steam cavity and all can press to Connection Block, blocked shot and sealing member, and therefore the structure of this Connection Block at steam cavity place is pressure-resistance structure.
In order to sufficiently long air flow path can be formed in steam cavity, as preferably of the present invention, the bearing of trend of described induction opening and the air gate line of centers along blocked shot on Connection Block is dislocatedly distributed, and described induction opening is less than the distance of air gate to adapter sleeve to the distance of adapter sleeve.So, the path of gas flowing can with longer length distribution in steam cavity.But in order to reach the longest gas flow paths, described induction opening and air gate are positioned at the both sides of Connection Block.
Aseptic filling valve is in vertical state when using, and induction opening is positioned at above air gate in a state of use, and as preferably of the present invention, described air gate is positioned at the end of steam cavity, and the side of the bottom of such steam cavity and the inwall of air gate maintains an equal level.The condensed water that the advantage of this structure is formed by aseptic filling valve temperature is low when being to start aseptic filling valve can be discharged from air gate, improves the sterilization effect of steam cavity.
The blocked shot portion faces of turnover aseptic area is necessary for germ-free condition, and in vapor chamber the sterile medium of High Temperature High Pressure to needing certain hour during blocked shot surface sterilizing, if exchanged for the germ-free condition on blocked shot surface by elapsed time, the action of blocked shot then can be made slack-off, reduce the work efficiency of aseptic filling valve.Therefore, adopt the scheme allowing the blocked shot portion faces of turnover aseptic area remain germ-free condition in the present invention, namely preferably of the present invention, the length of described steam cavity is more than or equal to the maximum spacing between sealing surface I and sealing surface II.Spacing between sealing surface I and sealing surface II is relevant with the movement position of blocked shot, this distance values equals the straight-line displacement amount of blocked shot, namely the length of steam cavity is more than or equal to blocked shot straight-line displacement amount, so blocked shot only enters in steam cavity when blocked shot does not contact with valve body with the position of aseptic area residing after valve body contact, and can not pass steam cavity.
The mode of operation of blocked shot is linear reciprocating motion, and the air-tight structure being positioned at steam cavity two ends is applicable to this mode of motion of blocked shot.Blocked shot is column structure, if blocked shot generation rotation in working process, on the direction around blocked shot line of centers, cliding friction can be produced to air-tight structure, hermetically-sealed construction seal form is in the direction in which changed and cannot play best vapor seal effect, air-tight structure is impaired thus.In order to prevent blocked shot rotation in the course of the work, restriction blocked shot only does linear reciprocating motion axially, as preferably of the present invention, the piston rod of described double stroke cylinder is fixedly connected with by anti-rotation assembly with between blocked shot, described anti-rotation assembly comprises contiguous block, orienting lug, described contiguous block is provided with the mounting groove I that cross-sectional plane is T-shaped, the cross-sectional plane of described blocked shot one end is T-shaped, described blocked shot is embedded in mounting groove I by this end that cross-sectional plane is T-shaped and is connected with contiguous block, described orienting lug is fixedly connected on contiguous block, described contiguous block is fixedly connected with the piston rod of double stroke cylinder, described adapter sleeve is provided with two parallel confined planes, the line of centers bearing of trend of described blocked shot is parallel to confined planes, described orienting lug between two confined planes and with confined planes free-running fit.By the connection mode of T-shaped structure between contiguous block and blocked shot, also free-running fit between the two, makes contiguous block be connected as a single entity with blocked shot on the direction of the line of centers around blocked shot; Orienting lug and contiguous block are also connected as a single entity, between the confined planes that orienting lug provides at adapter sleeve, motion, blocked shot are again by the guiding restriction of sealing shroud, therefore make contiguous block can only at the bearing of trend of blocked shot line of centers or the square upward movement of bearing of trend being parallel to blocked shot line of centers.
Anti-rotation assembly plays the effect connecting piston rod and blocked shot, impels blocked shot only to perform linear reciprocating motion under the guiding restriction of the confined planes of adapter sleeve simultaneously.
