Embodiment
As shown in the figure, a kind of guide tracked vacuum connecting rod push-pull valve, comprises valve body 2; In described valve body 2 active chambers, be provided with driving mechanism; Described driving mechanism comprises the guide rail 6 of two symmetrical parallel; Described guide rail 6 comprises upper strata trackwork face 601 and lower floor's track working surface 602; One end of described lower floor track working surface 602 is furnished with lower deep gouge 12; Described upper strata trackwork face 601 is provided with the vavle shelf 7 that fixedly connects guide wheel mechanism I4; Described guide wheel mechanism I4 and upper strata trackwork face 601 slide and join; Described lower floor track working surface 602 is provided with the valve plate 8 that fixedly connects guide wheel mechanism II5; Described guide wheel mechanism II5 and lower floor's track working surface 602 slide and join; Described valve body 2 one end are fixed with cylinder 1; The push rod 13 of described cylinder 1 joins through hinge 3 and the end of vavle shelf 7; Between described vavle shelf 7 and valve plate 8, be provided with connecting rod 11; Described connecting rod 11 is coupling with vavle shelf 7 and valve plate 8 activities respectively.
Shown in Figure 1, valve plate 8 of the present invention is provided with seal ring.Certainly, need also can be provided with insulating assembly 10(or movable water-cooled assembly 14 according to design).
Shown in Figure 2, valve plate 8 of the present invention adopts water-cooling valve plate structure; In described valve body 2 active chambers, be provided with water-cooled and be flexible coupling 9; A be flexible coupling port of 9 of described water-cooled communicates with the internal cavity of valve plate 8, and its other end communicates with movable water-cooled assembly 14 ports on valve body 2.
Shown in Figure 3, guide rail 6 of the present invention adopts double layer construction.Guide rail 6 of the present invention, in the time of processing and fabricating, can adopt integrative-structure.Upper end portion is upper strata trackwork face 601.In guide rail 6 central region, level has rail slot 15; One end of rail slot 15 is furnished with lower deep gouge 12.Rail slot 15 entirety are L-type.The working end of guide wheel mechanism II5 is placed in rail slot 15, and slides and join with lower floor track working surface 602.Rail slot 15 can retrain the motion of valve plate 8, and in the time that guide wheel mechanism II5 reaches predetermined design position, the working end of guide wheel mechanism II5 can be slipped in lower deep gouge 12, can order about like this valve plate 8 and move down.
Driving mechanism of the present invention relies on guide rail 6 to realize guiding, and guide rail 6 is not associated with valve body generation, and therefore the precision of guide rail 6 is not affected by the machining accuracy of valve body 2, reaches the object of simplifying technique.
The present invention also can adopt insulating assembly to substitute water-cooled assembly to prevent that valve plate is because hyperthermia radiation is out of shape.
Driving mechanism of the present invention relies on guide rail 6 to realize the compound motion of horizontal and vertical in movement process, relies on the precision of guide rail 6 and the elastic force of cushion rubber to realize sealing.
In movement process, cylinder 1 connects hinge 3 through push rod 13 to be promoted vavle shelf 7 and travels forward.Because guide rail 6 adopts double layer construction, guide wheel mechanism I4 is (upper strata trackwork face 601) on guide rail upper strata, parallel motion all the time; Rail slot 15 is guide rail lower floor (forming lower floor's track working surface 602).Guide wheel mechanism II5 is along guide rail lower floor contour motion the contour motion of L-type rail slot 15 (along).In the time that guide wheel mechanism II5 moves to predetermined design position, because guide rail lower floor profile is L-type, therefore arrive behind this position, under the torsional interaction that guide wheel mechanism II5 forms at connecting rod 11, can move downward with valve plate 8, power is passed to valve plate 8, produce downward power, play the effect of press seal, and complete whole pass valve events.While driving valve, valve events is corresponding with closing, and does not repeat herein.
Be understandably, above about specific descriptions of the present invention, only for the present invention is described, and be not limited to the described technological scheme of the invention process example, those of ordinary skill in the art is to be understood that, still can carry out part to the present invention and adjust or be equal to replacement, to reach identical technique effect; As transmission adopts motor or manual drives, and in the structure of removing water-cooled, insulating assembly without the non-dusting occasion of temperature occasion, use needs as long as meet, all within protection scope of the present invention.
