For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of end cap of switching valve, it comprises end cap body, end cap body be shaped as disc, it is characterized in that: on described end cap body, offer the first circular trough, the center of circle of the first circular trough is positioned on the axis of end cap body; One side of end cap body is fixedly installed ring baffle, ring baffle stretches out end cap body, the center of circle of the inner ring of ring baffle is positioned on the axis of end cap body, the diameter of the inner ring of ring baffle is identical with the diameter of the first circular trough, and the diameter of the outer ring of ring baffle is less than the diameter of end cap body; The inner ring of the first circular trough and ring baffle forms through hole, offers the first groove of annular on the inwall of through hole, is provided with the first seal ring matching in the first groove; Described end cap body and ring baffle are made by teflon.
On the outer wall of described end cap body, offer the second groove of annular, the second seal ring matching is set in the second groove.
The cross section of described the second groove is semicircle, and the second described seal ring is O type circle.
The first described seal ring is oil sealing.
The diameter of described end cap body is 81.5 millimeters, and the diameter of the inner ring of ring baffle is 27 millimeters, and the diameter of the outer ring of ring baffle is 65 millimeters, and the diameter of the first circular trough is 27 millimeters.
The beneficial effects of the utility model are: in the utility model, end cap body and ring baffle are connected to one, the first circular trough of end cap body and the inner ring of ring baffle form through hole, in through hole, the axle being connected with switching valve can be installed, guarantee the installation of switching valve; On the inwall of through hole, offer the first groove of annular, in the first groove, be provided with oil sealing, on the outer wall of end cap body, offer the second groove of annular, in the second groove, be provided with the O type circle matching, the cooperation of oil sealing and O type circle, guarantee the sealability of the end cap of atmosphere switch valve or vacuum switching valve, be conducive to the generation of malleation, negative pressure in switching valve; End cap body and ring baffle are made by teflon, can avoid end cap to be corroded by sour vapour.
The utility model is reasonable in design, simple in structure, be easy to manufacture, be convenient to dismounting, guaranteed the sealing of the end cap of sealing-tape machine atmosphere switch valve or vacuum switching valve, can avoid end cap to be corroded by sour vapour.
