Embodiment Construction

[0009] as attached figure 1 As shown, the present invention comprises pot body 1 and pot cover 2, and pot cover 2 lower surface periphery is provided with sealing ring 3, and sealing ring 3 diameter size matches with pot body 1 opening size, and sealing ring 3 ring body interior is along ring body axis An airtight cavity 31 is provided, and the ring body cross section of the sealing ring 3 is trapezoidal.

[0010] In order to make the deformation of the sealing ring too large when the negative pressure in the reaction pot is too large, a groove 11 matching the sealing ring 3 is arranged on the opening end surface of the pot body 1, and the sealing ring 3 and the groove 11 have an interference fit . Because the cross section of the ring body of the sealing ring 3 is trapezoidal, the sealing ring is completely embedded in the trapezoidal groove of the lower flange, so that the shape of the sealing ring is fixed and will not be easily deformed.

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 [0001] The invention relates to a sealing system, in particular to a sealing system of a chemical raw material reaction pot. Background technique [0002] Now the traditional reaction pot adopts hydraulic pressure to open and close the lid. In the negative pressure production process, it needs to be vacuumed. Sometimes the sealing ring is easily squeezed and deformed by the atmospheric pressure. If the sealing ring is often squeezed and deformed, the life of the sealing ring will be reduced. . At the same time, when the sealing ring is deformed to a certain extent, the reaction pot will leak air. The reaction in the reaction pot is caused by the fact that the reaction conditions cannot reach the normal reaction conditions and the reaction products are unqualified, resulting in an increase in the rejection rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sealing ring of a chemical raw mate...
