Abstract
The invention relates to a sealing system, in particular to a sealing system of a chemical raw material reaction pot. The sealing system of the chemical raw material reaction pot comprises a pot body and a pot cover, wherein a sealing ring is arranged at the periphery of the lower surface of the pot cover; the diameter of the sealing ring is matched with the opening size of the pot body; a sealed cavity is formed in the sealing ring body along a ring body axis; further, the cross section of the sealing ring body is trapezoidal; further, a groove matched with the sealing ring is arranged on the end face of the opening of the pot body; and the sealing ring is in interference fit with the groove. The sealing system can be applied to various chemical raw material reaction pots.
Description
Technical field
The present invention relates to a kind of sealing system, especially a kind of sealing system of chemical raw material reaction pot.
Background technique
Traditional reaction pot closes lid owing to adopt hydraulic pressure to uncap now, and the production technology adopting negative pressure will vacuumize, and seal ring is easily by barometric pressure extrusion-deformation sometimes, if the frequent extrusion-deformation of seal ring, the life-span of seal ring can reduce.Simultaneously, when sealed ring deformation arrives to a certain degree, the phenomenon that reaction pot can leak air.Cause the reaction in the reaction pot to cause reaction product defective owing to reaction region can't reach normal reaction conditions, the phenomenon that the products waste rate raises.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of seal ring of chemical raw material reaction pot, solves short problem of seal ring life-span.
In order to solve the problems of the technologies described above, the present invention includes pot body and pot cover, pot cover lower surface periphery is provided with seal ring, and the seal diameter size is complementary with pot body openings of sizes, and seal ring ring body inside is provided with closed cavity along the ring body axis.
Further, described seal ring ring body cross section is trapezoidal.
Further, be provided with groove, described seal ring and the groove interference fit of mating with seal ring on the described pot body open end.
Advantage of the present invention is, improved the working life of seal ring, improved sealing effect.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes pot body 1 and pot cover 2, pot cover 2 lower surface peripheries are provided with seal ring 3, and seal ring 3 diameter are complementary with pot body 1 openings of sizes, seal ring 3 ring body inside are provided with closed cavity 31 along the ring body axis, and described seal ring 3 ring body cross sections are trapezoidal.
When making that negative pressure is excessive in the reaction pot, the distortion of seal ring is excessive, is provided with the groove 11 with seal ring 3 couplings on described pot body 1 open end, described seal ring 3 and groove 11 interference fit.Because seal ring 3 ring body cross sections are trapezoidal, and seal ring is embedded in the dovetail groove of lower flange fully, the shape of seal ring is just fixing to some extent like this, can not be out of shape easily.
