Description
Technical field
The utility model relates to a kind of autoclave, particularly a kind of minitype high voltage still being easy to open inner cap.
Background technology
Autoclave is the pressure vessel of sealing, and general minitype high voltage still is made up of metal shell and polytetrafluoroethylliner liner, can carry out chemical reaction at high temperature under high pressure.Inner bag is made up of inner lining and inner bladder cover, inner bladder cover makes conic lid usually on inner lining, inner lining opening beveling, with inner bladder cover close contact, the effect of sealing inner container reactant liquor is played under the extruding of upper and lower metallic gasket, and after reaction terminates cooling, owing to being react under high-temperature and high-pressure conditions, a small amount of air is had to be extruded, liquid is become after the reactant liquor steam cooling of high pressure, internal bladder cavity has certain vacuum after the cooling period, inner bladder cover is caused to be held, because inner bladder cover is made up of polytetrafluoroethylene (PTFE), hardness is not high, therefore, very difficult hand is turned on, if turn by force, very easily inner bladder cover is twisted distortion, also do not reach the object of unlatching, and other instruments cannot use.In laboratory, generally with screwdriver sled, will be damaged with the inner bladder cover that polytetrafluoroethylene (PTFE) is made like this, serious words will cause leakage, also can lose time.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and provide a kind of reasonable in design, structure is simple, is easy to open the minitype high voltage still of inner cap.
Technical problem to be solved in the utility model is realized by following technical scheme, the utility model is a kind of minitype high voltage still being easy to open inner cap, comprise kettle, the kettle cover be threaded with kettle and the inner bag be located in kettle, the convenient apical pore taking out inner bag is provided with at autoclave body bottom, the sealing gasket covering apical pore is provided with in kettle below inner bag, be characterized in, the inner bladder cover that described inner bag comprises inner lining and is threaded with inner lining, seal cover is provided with between inner bladder cover and kettle cover, the top of seal cover is provided with the projection facilitating turn seal cover, the bottom of seal cover is provided with draw-in groove, the top of inner bladder cover is provided with the upper convex portion be contained in draw-in groove, the bottom of inner bladder cover is provided with the lower protuberance coordinated with inner lining inwall.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, is easy to open in the minitype high voltage still of inner cap: be provided with notch at the monosymmetric of described projection above-described.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, is easy to open in the minitype high voltage still of inner cap above-described: the height of described projection is 3-8mm.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, is easy to open in the minitype high voltage still of inner cap: described draw-in groove is strip above-described.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, is easy to open in the minitype high voltage still of inner cap above-described: described sealing gasket is circular stainless steel gasket.
The utility model is by establishing upper convex portion and draw-in groove, and seal cover can drive inner bladder cover turn, and lifting surface area is large, can not destroy the structure of inner bladder cover, while opening inner bladder cover smoothly, ensure the complete of inner bladder cover; If protruding, conveniently turn seal cover, save the opening time, improve unlatching efficiency; Set protuberance, coordinate with inner lining, ensure that good sealing effectiveness.Compared with prior art, it is reasonable in design, easy to operate, improves the opening speed of inner bag.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure chart of seal cover;
Fig. 3 is the structure chart of inner bladder cover.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, with reference to Fig. 1-3, a kind of minitype high voltage still being easy to open inner cap, comprise kettle 4, the kettle cover 1 be threaded with kettle 4 and the inner bag be located in kettle 4, the convenient apical pore 7 taking out inner bag is provided with bottom kettle 4, the sealing gasket 6 covering apical pore 7 is provided with in kettle 4 below inner bag, the inner bladder cover 3 that described inner bag comprises inner lining 5 and is threaded with inner lining 5, seal cover 2 is provided with between inner bladder cover 3 and kettle cover 1, the top of seal cover 2 is provided with the projection 9 facilitating turn seal cover 2, the bottom of seal cover 2 is provided with draw-in groove 10, the top of inner bladder cover 3 is provided with the upper convex portion be contained in draw-in groove 10, the bottom of inner bladder cover 3 is provided with the lower protuberance 8 coordinated with inner lining 5 inwall.
Embodiment 2, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: described protruding 9 be monosymmetricly provided with notch, conveniently place rotating tool, ensure protruding smooth turn.
Embodiment 3, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: the described height of protruding 9 is 3mm.
Embodiment 4, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: the described height of protruding 9 is 8mm.
Embodiment 5, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: the described height of protruding 9 is 6mm.
Embodiment 6, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: described draw-in groove 10 is in strip.
Embodiment 7, is easy to open in the minitype high voltage still of inner cap described in embodiment 1: described sealing gasket 6 is circular stainless steel gasket.
After reaction terminates, open kettle cover 1, instrument of using from apical pore 7 by inner bag together with after seal cover 2 jack-up, inner bag is taken out in kettle 4, the projection 9 at seal cover 2 top is clamped with hand or other instruments, turn seal cover 2, drives the upper convex portion at inner bladder cover 3 top, thus overall turn inner bladder cover, because the lifting surface area on inner bladder cover is large, inner bladder cover, not easily by stubborn distortion, can also ensure the smooth unlatching of inner bladder cover, easy to operate.
