Abstract
The utility model relates to a seal structure of a pressure vessel, in particular to a seal structure of a pressure vessel cover, which mainly solves the technical problems of complicated operation and troublesome closing in prior seal structure of pressure vessel sterilizer cover. The technic proposal of this utility model is that a seal structure of a pressure vessel comprises a pot cover and a cylindrical pot body. The combination end face between the upper flange of the pot cover and the lower flange of the pot body is provided with spaced chimbs and grooves. The chimbs of the upper flange are fitted with the grooves of the lower flange, and the grooves of the upper flange are fitted with the chimbs of the lower flange. The inner end face of the lower flange is provided with a self-expanding seal ring, and the pot cover is fixed on an above flip cover by a rotary bearing, and the flip cover is connected with the pot body by a hinge. The flip cover is provided with a rotating handle connected with a driver below, which is meshed with an idler meshed with the rack in the periphery of the pot cover. The utility model can be applied in vertical pressure steam sterilizer.
Description
Technical field: the utility model relates to a kind of hermetically-sealed construction of pressure vessel, particularly a kind of hermetically-sealed construction of pressure vessel pot cover.
Background technology: the present pressure vessel sterilizer that uses, the dual mode that is sealedly connected with of its pot cover and pot body, a kind of is the flip-shell structure, another kind is the moving type structure.Its pot cover of pressure vessel sterilizer of flip-shell structure is connected with a pot body by hinge, pot cover and pot body by four sealing screw rods up and down the flange seal circle compress sealing owing to operate at every turn, all to screw and unscrew the sealing screw rod, operate comparatively numerous and diverse.Moving type structural pressure sterilizing containers device, be fixed with rotation hand wheel on its pot cover, rotatable arc crossbeam is installed on the screw rod between pot cover and the rotation hand wheel, rotatable arc crossbeam is installed on pot surface column, also have the column of a trough of belt mouth on the opposite of pot body cavity volume, the end of described notch and arc crossbeam is complementary.Close when covering, rotate the arc crossbeam, make its end all enter shaft notch, with the safety plug locking, rotation hand wheel makes pot cover close a pot body and compresses sealing then.Need rotate the arc crossbeam and enter shaft notch owing to close lid, in the aligned notches process, if finger at the notch place, just crushes finger easily or damages.And, also be easy to generate poorly sealed defective by the mode that handwheel screws.
Summary of the invention: the purpose of this utility model provides a kind of hermetically-sealed construction of pressure vessel pot cover of easy to operate, good seal.Mainly solve the technical problems such as comparatively numerous and diverse, the closed effort of operation of the hermetically-sealed construction existence of existing pressure vessel sterilizer pot cover.
The technical solution of the utility model is: a kind of hermetically-sealed construction of pressure vessel pot cover, comprise pot cover and pot body, the pot body is a cylinder, the pot cover upper flange is the alternate layout with groove of chimb with pot body lower flange in conjunction with end face, upper flange chimb and lower flange groove match, upper flange groove and lower flange chimb match, the lower flange inner face is provided with the self expansion sealing ring, the pot cover top is provided with renovates, and pot cover is fixed on by rolling bearing and renovates, and renovates by hinge to connect with pot sports association, renovated one and revolved handle, this revolves under the handle and connects a driving wheel, driving wheel and idle pulley engagement, idle pulley and the engagement of pot cover periphery tooth bar.The idle pulley diameter is greater than the driving wheel diameter.
The beneficial effects of the utility model are: because the pressure vessel pot cover has adopted the gear graduation link gear, reached the big torsion action of using simple low-power to finish very complicated, pressure vessel upper-lower seal flange circle concaveconvex structure is coincide mutually, reached the requirement of sealing, and realized light and handy easy quick operating valve mode, this built-in operating structure, not only attractive in appearance but also safety.
Description of drawings:
Fig. 1 is the utility model structural representation front view
Fig. 2 is the utility model structural representation vertical view
Among the figure: the 1-upper flange, the 2-lower flange, the 3-sealing ring, 4-renovates, the 5-hinge, 6-revolves handle, 7-driving wheel, 8-idle pulley, 9-tooth bar.
The specific embodiment: with reference to Fig. 1,2, a kind of hermetically-sealed construction of pressure vessel pot cover, comprise pot cover and pot body, the pot body is a cylinder, pot cover upper flange 1 is the alternate layout with groove of chimb with pot body lower flange 2 in conjunction with end face, upper flange chimb and lower flange groove match, upper flange groove and lower flange chimb match, and the lower flange inner face is provided with self expansion sealing ring 3, and the pot cover top is provided with renovates 4, pot cover is fixed on by rolling bearing and renovates, renovate 4 and connect with a pot sports association by hinge 5, renovated one and revolved 6, this revolves under the handle and connects a driving wheel 7, driving wheel and idle pulley 8 engagements, idle pulley 8 and 9 engagements of pot cover periphery tooth bar.Because idle pulley 8 diameters are greater than driving wheel 7 diameters.Make and to revolve when rotating more laborsavingly, close when cover, at first will revolve and go to an end to 6 that this moment, the male and fomale(M﹠F) of upper flange 1 just in time snapped in the male and female face of lower flange 2, will revolve then and go to the other end to 6, drive pot cover and rotate and just in time will go up lower flange and lock and seal.
