Description
Technical field
The present invention relates to a kind of sealing device, specifically, relate to a kind of sealing device that is used for the micro-wave digestion jar.
Background technology
In the micro-wave digestion field; Mostly sealing device commonly used in the market is to combine with seal cover and tank body, and as shown in Figure 1, bearing plate 6 one ends and seal cover 1 are affixed; The bowl end of the other end and obturating cup 2, is affixed; Obturating cup 2 is processed by gathering PTFE, and its bowl wall shirt rim is very thin, and the rim of a bowl of obturating cup 2 is towards the jar end direction of tank body 3 during installation.Its sealing principle is: tank body 3 internal gas pressures strut the bowl wall of obturating cup 2 during sealing, make bowl wall and tank body 3 inwalls fit, thereby play the effect of sealing.When the sealing end needed pressure release, obturating cup 2 can move to relief pipeline 4 porch until bowl wall shirt rim to moving away from the direction at the bottom of the jar, and internal gas overflows from relief pipeline 4, thereby plays the effect of pressure release.
But the deficiency of existing apparatus is,
One, during pressure release, the ambient atmos pressure that gas pressure receives much larger than outer wall in the jar that the obturating cup inwall receives, turning up in a bowl wall shirt rim, causes obturating cup to use repeatedly, increased production cost;
When two, a jar internal gas pressure was mesolow, sealing effectiveness was poor, because jar internal gas pressure is big inadequately, can't the bowl wall of obturating cup be strutted fully and make itself and inner tank wall applying.
Summary of the invention
In order to address the above problem, the present invention provides a kind of sealing device that is used for the micro-wave digestion jar, can solve the high and not good technical problem of sealing effectiveness of use cost in the prior art.
For realizing above-mentioned purpose, the present invention provides a kind of sealing device that is used for the micro-wave digestion jar, comprises seal cover, sealing ring and bearing plate, and said bearing plate one end and seal cover are affixed; Said sealing ring is arranged between seal cover and the bearing plate.Limit the position of fixing sealing ring through seal cover and bearing plate, make interior stable the fitting tightly of wall energy of itself and the parts that need sealing, the sealing effectiveness of assurance device.
Further, said sealing ring is closed fully circulus.Its effect is to guarantee that the interior wall energy of sealing ring and the parts that need sealing has complete the fitting tightly of a circle, thus the sealing effectiveness of assurance device.
Further, between said sealing ring and seal cover outer wall for closely to contact.Its effect is the sealing effectiveness of assurance device.
Further, between said sealing ring and bearing plate outer wall for closely to contact.Its effect is the sealing effectiveness of assurance device.
Further, said bearing plate is not a concave curved surface with the surface of the affixed end of seal cover.The effect of bearing plate is the pressure in the holder, thus moving sealed closure, it is can be more concentrated for pressure that its surface is made as concave curved surface, jar internal pressure makes that moving of seal cover is sensitiveer.
Further, between said seal cover and bearing plate for being spirally connected.Its effect is to fix sealing ring, guarantees that the sealing effectiveness of counteracting tank is good.
Further, said bearing plate is provided with the pilot pin of a convexity; Said seal cover is provided with the locating hole of a depression, and the inside radius size of pilot pin outer radius and locating hole is complementary, and through pilot pin is inserted in the locating hole, can realize the closely affixed of bearing plate and seal cover.Its effect is to fix sealing ring, guarantees that the sealing effectiveness of counteracting tank is good.
Further, said sealing ring material is the material that fluorubber etc. can not absorb microwave, and the sealing ring outer surface can also be coated with one deck soluble poly tetrafluoroethene (hereinafter referred PFA).
The advantage that the present invention is used for the sealing device of micro-wave digestion jar is:
One, can repeat repeatedly to use, reduce production costs;
Two, no matter install interior air pressure size, sealing effectiveness is all fine;
Three, safety coefficient is high.
