Abstract
In order to solve the technical problem who a little glues water clock hangover phenomenon, the utility model provides a dispensing valve to high viscosity medium for the point of high viscosity medium is glued. This dispensing valve's characterized in that: it is sealed firmly through the cylinder between case left end and the valve body, be equipped with the sealing washer between case right -hand member and the valve body, the case passes through threaded connection with the cylinder, and the case aperture is adjustable, be equipped with the sealing washer between valve gap and the valve body, part little in the middle of the case structure forms media channel, and the left end plays plunger and threshold switch dual function, the medium passes through with the interior annular channel of valve body from the case is outer. The beneficial effects of the utility model are that: 1, adopt the cylinder sealed firmly, it is sealed reliable. 2, annular channel is wideer, and is littleer to the high viscosity resistance of medium, goes out to glue more smoothly. 3, the case aperture is adjustable, and it is controllable to go out the solation volume.
Description
Technical field
This utility model relates to a kind of valve for dispensing glue, belongs to spot gluing equipment field.
Background technology
Dispensing technology be glue, oils and fats, copper brazing glue etc. are had the spreading medium of non-Newtonian fluid of viscosity higher, embedding, point drip on certain product, play the effects such as fixing, encapsulation, embedding.
Traditional some glue is coated with to be carried out position and is substantially plane, and basic effect is quantitative repetition, namely does identical action with certain fixing amount multiple position in the plane, for instance identical point, straight line, circular arc etc..Existing glue is generally adopted air pressure type of drive plastic emitting, such plastic emitting mode is to some full-bodied media, traditional glue dispensing valve is generally adopted the mode of conical surface seal or flat seal, and to the paste having solid particle, such structure also exists certain problem.For paste, both structures when valve closing due to solid particle exist, it may appear that close not dead phenomenon, water clock occur.During valve opening, due to the impetus of valve opening moment spool, medium has again the phenomenon of ejection.When closing valve, due to the extruding phenomenon of medium, have again conditions of streaking.
Summary of the invention
In order to solve the technical problem of above-mentioned some glue water clock conditions of streaking, this utility model provides the version of a kind of new type of valve, for the some glue of high viscosity medium.
Key technology of the present utility model is in that: the sealing surface of threshold switch is the face of cylinder, and critical piece includes syringe needle 1, fixing nut 2, valve gap 3, valve body 4, spool 5, cylinder 8, nut 7, inner seal ring 6 and exterior seal ring 9.
Syringe needle 1 is outlet for dispensing glue, it is positioned at the left end of valve module, syringe needle is contained on valve gap 3 by fixing nut 2, valve gap 3 is connected with valve body 4 by screw thread, spool 5 is positioned at the center of valve body 4, and spool 5 is connected with cylinder 8 by screw thread, and moves left and right with cylinder 8 action, thus controlled valve, control the break-make of medium.Inner seal ring 6 between spool 5 and valve body 4 is used for preventing medium from overflowing from rear end, and nut 7 is for the connection between locking spool 5 and cylinder 8.Medium enters valve body 4 from entrance, and the middle part of spool 5 is less, and the gap between valve body 4 is the passage of medium, and the short column face of spool 5 left end is sealing surface.Spool 5 moves to left, and the left side of valve body 4 is left in short column face, enters the cavity in valve gap 3, and valve is opened, and short column moves to right entrance valve body 4, valve closing.
This glue dispensing valve is characterised by: firmly sealed by cylinder between spool 5 left end and valve body 4, it does not have the soft sealing material of rubber.
This glue dispensing valve is characterised by: be provided with inner seal ring 6 between spool 5 right-hand member and valve body 4.
This glue dispensing valve is characterised by: spool 5 and cylinder 8 are threaded connection, and spool 5 aperture is adjustable, and the spacing namely opening back valve core 5 end face and valve body 4 end face is adjustable.
This glue dispensing valve is characterised by: be provided with exterior seal ring 9 between valve gap 3 and valve body 4.
This glue dispensing valve is characterised by: part little in the middle of spool 5 structure forms medium channel, and left end plays plunger and threshold switch dual function.
This glue dispensing valve is characterised by: medium passes through with valve body 4 annular passage from spool 5.
The beneficial effects of the utility model are: 1, adopt cylinder firmly to seal, and seal reliable.2, circular passage is wider, and high viscosity medium resistance is less, and plastic emitting is more smooth and easy.3, spool aperture is adjustable, goes out flow adhesive controlled.
Accompanying drawing explanation
Fig. 1 is this utility model generalized section.
Detailed description of the invention
Below in conjunction with accompanying drawing and citing, describe detailed description of the invention of the present utility model in detail.
As it is shown in figure 1, this utility model glue dispensing valve is for high viscosity medium.It is characterized by that the sealing surface of threshold switch is the face of cylinder, critical piece includes syringe needle 1, fixing nut 2, valve gap 3, valve body 4, spool 5, cylinder 8, nut 7, sealing ring 6 and sealing ring 9.
Syringe needle is outlet for dispensing glue, is positioned at the left end of valve module, and syringe needle is contained on valve gap by fixing nut, valve gap is connected with valve body by screw thread, and spool is positioned at the center of valve body, and spool passes through screw thread and cylinders, and move left and right with cylinder action, thus controlled valve, control the break-make of medium.Sealing ring between spool and valve body is used for preventing medium from overflowing from rear end, and nut is for the connection between locking spool and cylinder.Medium enters valve body from entrance, and the middle part of spool is less, and the gap between valve body is the passage of medium, and the short column face of spool left end is sealing surface.Spool moves to left, and the left side of valve body is left in short column face, enters the cavity in valve gap, and valve is opened, and short column moves to right entrance valve body, valve closing.
The cylinder of spool left end had both played the effect of valve switch, also corresponded to a plunger, had suck-back glue effect during closedown, it is prevented that hangover；Push effect is had, plastic emitting when can assist beginning when opening.
