Description
Technical field
The utility model relates to vacuum reversal valve, specifically refers to a kind of new type of airflow vacuum reversal valve.
Background technique
Automatic single-plate feeder is the self-feeding being realized veneer by vacuum pump control vacuum chuck absorption and release movement.But owing to directly controlling vacuum chuck absorption and release movement by the keying of vacuum pump, easily to cause the control action of equipment slowly, control poor sensitivity, situation that unfailing performance is low.Control the speed of vacuum chuck action so existing many use selector valves reach quickening vacuum pump and improve sensitivity.Existing selector valve mainly comprises valve body, drives cylinder and valve gap, and valve body two ends connect vacuum pump and vacuum chuck respectively.By driving the telescopic action of cylinder to make valve gap close valve body to reach the negative pressure controlled in selector valve, thus reach the absorption and release movement that control vacuum chuck.When carrying out absorption action, valve body directly will form negative pressure state, not only needs to consider that valve gap closes the closure effect at place, also will guarantee the sealing driving cylinder joint simultaneously.So, the accurate performance of selector valve will be on the hazard, and causing trouble takes place frequently, and the production technology of product and cost of production also can rise thereupon.Simultaneously due to selector valve work time, drive the piston rod of cylinder to be in valve body, long-term negative pressure state also can cause it to occur being out of shape, and then the generation of causing trouble.
Model utility content
For above-mentioned prior art Problems existing, the utility model is to provide a kind of new type of airflow vacuum reversal valve, simple and practical, on the basis that action sensitivity is high, by changing its structure, strengthen reliability, stability and accuracy that selector valve uses, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is:
A kind of new type of airflow vacuum reversal valve, comprise valve body, drive cylinder and three-way pipe, described valve body side is provided with a flow-off, and described valve body is provided with left side and right side, and described left side, right side are connected with flow-off; There is described driving cylinder described valve body right side by end cap flange disk device, and the piston rod of described driving cylinder connects a valve blade; The left side of described valve body is connected with a sealed end facial canal by pivot flange dish, and one end that described sealed end facial canal does not connect valve body is connected with described three-way pipe.
Described piston rod is provided with a gasket seal in the outside of described valve blade.
Described valve body is provided with one for the mounting plate of location and installation effect.
Advantage of the present utility model:
(1) the utility model is simple and practical, on the use basis that action sensitivity is high, change its structure, controlled the positive/negative pressure state in sealed end facial canal and three-way pipe by the keying of valve blade, thus reach the action controlling vacuum chuck release and absorption.No matter vacuum chuck adsorbs or release, is all in atmospheric pressure state in valve body, avoiding driving cylinder easily to cause the harm of deformed damaged because being in negative pressure for a long time, ensureing the stability that selector valve uses and reliability.(2) the utility model opens and closes what change by valve blade is positive/negative pressure state in sealed end facial canal and three-way pipe, the installation sealing of driving cylinder does not affect the sealability in three-way pipe, reduce gas leakage point, ensure the accuracy that selector valve uses and endurance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Embodiment
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to Fig. 1-2, a kind of new type of airflow vacuum reversal valve, comprise valve body 5, drive cylinder 1 and three-way pipe 9, described valve body 5 side is provided with a flow-off 5-1, and described flow-off 5-1 is the path for vacuum and the release of top blast pressure; Described valve body 5 is provided with one for the mounting plate 6 of location and installation effect, and mounting plate 6 can be arranged neatly according to the mounting point of selector valve; Described valve body 5 is provided with left side 5-3 and right side 5-2, and described left side 5-3, right side 5-2 are connected with flow-off 5-1; Described valve body 5 right side 5-2 has described driving cylinder 1 by end cap flange plate 2 device, and the piston rod of described driving cylinder 1 connects a valve blade 3, and described valve blade 3 is for the closed of valve 5 and release; Described piston rod is provided with a gasket seal 4 in the outside of described valve blade 3, and described gasket seal 4 is fitted and connected with valve blade 3, and described gasket seal 4 strengthens the sealing of closing face; The left side 5-3 of described valve body 5 is provided with a sealed end facial canal 7 by pivot flange dish 8, and one end that described sealed end facial canal 7 does not connect valve body 5 is connected with described three-way pipe 9.
Three-way pipe 9 connects vacuum pump and vacuum chuck, starts vacuum pump.
When carrying out absorption action, drive the piston rod of cylinder 1 to drive valve blade 3 to move forward, move to and closing seam end face pipe 7, make the three-way pipe 9 of communication seals end face pipe 7 be in closed negative pressure state, vacuum chuck carries out absorption action under negative pressure state.
When carrying out release movement, piston rod drives valve blade 3 to reset, and the air at flow-off 5-1 place flow into sealed end facial canal 7, and top blast pressure carries out release by flow-off 5-1, be in barotropic state in three-way pipe 9, vacuum chuck carries out release movement under barotropic state.
Simple and practical, that action sensitivity is high use basis changes structure of the present utility model, controls the positive/negative pressure state in sealed end facial canal 7 and three-way pipe 9 by the keying of valve blade 3 thus reach the release of vacuum chuck and the action of absorption.No matter vacuum chuck adsorbs or release, all atmospheric pressure state is in valve body 5, avoid driving the harm of easy deformed damaged of cylinder 1 because being in negative pressure and causing, and drive the installation sealing of cylinder 1 not affect sealability in three-way pipe 9, reduce gas leakage point, ensure stability, accuracy and endurance that selector valve uses.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
