Inner canister 2 outer rim near tank mouth is circumferentially arranged has bulge loop 21 upwards to support inner canister at oral area, and within inner canister is positioned over outer tank, makes to keep between interior tank wall and outer top tank structure certain space.Part 22 on inner canister tank mouth bulge loop 21 is to be separated by the distance of setting the annulus 22 of axis 23 vertical rotary around inner canister by the axis of pentagon Yu inner canister.
Interior cover 4 includes inner canister lid top wall the 401, first cylinder 402 and the second cylinder 404, first end of the first cylinder 402 is even arranged on the central authorities of the upper surface of inner canister lid top wall, second end is connected to the second cylinder 404, the diameter of the second cylinder 404 to the first cylinder is smaller, and the second end margin of such first cylinder forms ring-shaped step.
Outer rim near outer tank 1 tank mouth is circumferentially provided with external screw thread along outer tank.Outer cover 3 at least includes outer tank lid top wall 301 and outer cover skirt wall 302, and outer tank lid top wall 301 is preferably provided to prismatic, the most convenient to operate；Outer cover at least includes that outer tank lid top wall 301 and outer cover skirt wall 302, described outer cover skirt wall hang down from outer tank lid top wall neighboring, and circumferentially arranged has female thread to threaded with the external screw thread with outer tank；The central authorities of outer tank lid top wall are provided with the second through hole 303, for making the second cylinder 404 on interior cover 4 stretch out, be provided with sealing ring and seal when the second cylinder passes at described second through hole 303.The position of cover roof offset from center is provided with multiple bleeder port outside, such as bleeder port 7.
Micro-wave diminishing pot also includes manometer tube 6, and the second end of manometer tube 6 with the second cylinder 404 of interior cover is close to by described manometer tube 6 by voltage pipe nut 5, and voltage pipe nut 5 is provided with bleeder port 9.
Fig. 3 is the schematic cross-section of the inner canister tank mouth that the present invention provides, as shown in Figure 3, inner canister 2 outer rim near tank mouth is circumferentially arranged bulge loop 21, part 22 on inner canister tank mouth bulge loop 21 is to be separated by distance d of setting vertical around parallel with four limits 224 and with inner canister the axis 23 in pentagonal first limit 221 of annulus 22 of axis 23 vertical rotary of inner canister with the axis 23 of inner canister by pentagon, and pentagonal second limit is obtuse angle with the angle on the first limit；Pentagonal 3rd parallel with the 5th limit and with inner canister the axis in limit is parallel.
Fig. 4 is that the cross section of the interior cover that the present invention provides shows schematic diagram, as shown in Figure 4, interior cover 4 includes inner canister lid top wall the 401, first cylinder 402 and the second cylinder 404, first end of the first cylinder 402 is even arranged on the central authorities of the upper surface of inner canister lid top wall, second end is connected to the second end margin of the second cylinder 404, the second cylinder 404 and the first cylinder and forms ring-shaped step.The central authorities of inner canister lid top wall 401 are provided with the first through hole 403, and described first through hole is forming cone at inner canister lid top wall 401 lower surface, are so easy to assemble steam；First end of the first cylinder 402 is arranged on the upper surface of inner canister lid top wall, and the first end of the second end and the second cylinder 404 is connected, and the second end of the second cylinder 404 is free end.Second end margin of the second cylinder 404 and the first cylinder forms ring-shaped step, through hole in inner canister lid top wall, the first cylinder and the second cylinder communicates, for drawing pressure to measure pressure inside the tank, or after clearing up, artificially exit use, in the case of being not desired to measuring pressure, the second end of the second cylinder directly twists a plug, is also vent valve.In inner canister lid top wall, the first cylinder and the second cylinder one-body molded.The lower surface of inner canister lid top wall 401 is provided with annular groove 405, and described annular groove 405 is arranged on the periphery of the first through hole.Described annular groove be keystone ring connected in star, i.e. groove cross section radially be trapezoidal, described trapezoidal top 409 is 412 parallel with following, and the left side 410 is obtuse angle with the angle of top 409, and the right 411 is also obtuse angle with the angle of top 409.When outer cover 3 is threadedly tightened to outer tank tank mouth and interior cover 4 is pressed to inner canister tank mouth, the keystone ring that inner canister is 2 mouthfuls is embedded in keystone ring connected in star, so that interior sealing of tank cover inner canister.
Fig. 5 is the sectional view of the inner canister sealing of tank cover inner canister tank mouth that the present invention provides, as it is shown in figure 5, limit 409 trapezoidal in inner canister cover is 407 around the face of inner canister cover axis vertical rotary, trapezoidal limit 410 is 406 around the face of inner canister cover axis vertical rotary；Trapezoidal limit 411 is 408 around the face of inner canister cover axis vertical rotary.In inner canister tank mouth, pentagonal limit 221 is 227 around the face of inner canister axis vertical rotary, pentagonal limit 222 is 226 around the face of inner canister axis vertical rotary, the surfaces of revolution 407 is identical with the angle of the surfaces of revolution 227 and the surfaces of revolution 226 with the angle of the surfaces of revolution 406, so, when air pressure is little, the surfaces of revolution 407 is in close contact with the surfaces of revolution 227, the surfaces of revolution 406 is in close contact with the surfaces of revolution 226, when air pressure is big, the surfaces of revolution 407 and the surfaces of revolution 227 form gap, and the surfaces of revolution 406 and the surfaces of revolution 226 form gap, and gas releases from gap.
During use, within inner canister 2 is placed in outer tank 1, and the bulge loop of inner canister 2 tank mouth is made to be supported on outer tank 1 tank mouth；Then interior cover is placed in the tank mouth of inner canister, within making the tank mouth of inner canister be embedded in the annular groove of inner canister lid top wall lower surface；The second cylinder then making interior cover stretches out from the second through hole 303 of outer cover, is tightened in outer tank by outer cover, thus by the first cylinder, inner canister lid top wall is pressed to inner canister tank mouth；Finally utilize manometer tube nut 5 to be close to by second end face of catheter pressure and the second cylinder of interior cover 4, make counteracting tank be internally formed confined space.
In the present invention, inner canister and interior cover can utilize PFA material to prepare, and outer tank and outer cover can be prepared by nonmetallic materials such as PEEK or aerospace fibers.
When being loaded into needing the counteracting tank of the material cleared up to clear up, when inner canister internal pressure gradually rises, outer tank tops starts to produce deformation, when reaching the safety relief point of design, the deformation quantity of outer cover 3 reaches preset value, and now inner canister 2 produces a small gap with the sealing surface of interior cover 4, and gas flows out inner canister 2, automatic safe pressure release is realized from the pressure release of outer cover relief hole 7, the deformation quantity of outer cover 3 reduces, and the gap of sealing surface disappears, and counteracting tank pressurize works on.
Above in association with accompanying drawing, the operation principle of the present invention is described in detail.But those of ordinary skill in the art it should be understood that description is only for explaining claims.But protection scope of the present invention is not limited to description.Any those familiar with the art in the technical scope that the present invention discloses, the change that can readily occur in or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
