Detailed Description
The present invention will be further elucidated below with reference to the accompanying fig. 1-3 and the embodiments, it being understood that the embodiments described below are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-2, the sealing and leakage-proof component of the autoclave comprises a sealing ring 2, wherein the sealing ring 2 is formed in one step and is made of a high-temperature resistant material. Seal ring 2 can be dismantled and inlay on the cauldron body 1, seal ring 2 contains inlay portion 21 and extension 22, inlay portion 21 cross section is "T" shape, extension 22 cross section is "O" shape. The embedded part 21 consists of a sealing ring base body 211 and sealing ribs 25, the number of the sealing ribs 25 is not less than 2, the sealing ribs 25 are transversely arranged at equal intervals, and the sealing ribs are sequentially reduced from the joint of the sealing ring base body to the end part of the sealing ring base body; and reinforcing ribs are arranged between the locking sealing ribs. The effect of sealed muscle is the laminating of strengthening with the cauldron body, prevents to respond to the sealing washer when the extrusion simultaneously and collapses and cause not enough and produce the leakage of sealing force, and the strengthening rib makes this subassembly be difficult for producing the skew and empting when the assembly pressurized.
The sealing ring is provided with an L-shaped air channel 24, the air channel 24 extends from the embedded part 21 to the O-shaped middle inflating ring 23 of the extension part 22, and the kettle body 1 is provided with a channel 11 communicated with the air channel 24. As shown in fig. 3, a positioning pin 6 with a through hole is provided at the position where the channel 11 communicates with the vent channel 24 of the sealing ring, and the positioning pin 6 extends downwards from the autoclave body 1 to the vent channel 24 of the sealing ring, so as to keep the channel 11 and one end of the vent channel 24 at the same position. The diameter of the channel 11 and the air duct 24 is the same.
As shown in fig. 2, the sealing ring 2 is further provided with a blocking piece 3 at the outer side, and the blocking piece 3 is connected to the kettle body by a nut thread; the blocking piece 3 is used for further fixing the sealing ring 2, so that the sealing ring 2 is prevented from being sucked out or shifted from the embedding groove or the like due to negative pressure generated in the cover opening process.
As shown in fig. 1-2, an air pump 5 and an air pressure monitor 7 are connected to the outside of the air passage 24, the air pump 5 and the air pressure monitor 7 are arranged above the vertical center line of the autoclave body 1, and the air pump 5 is used for inflating and pressurizing the air ring 23 through the passage 11 and the air passage 24. As shown in FIG. 1, the air pump 5 and the air pressure monitor 7 are arranged above the vertical center line of the kettle 1.
The working principle is as follows:
sealing washer 2 can be dismantled and inlay on the cauldron body 1, will sealing washer air duct 23 port aligns with cauldron body passageway 11 port, inserts band-pass hole's locating pin 6 with fixed position, prevents that the circumferencial direction from producing the aversion, with 3 threaded connection of outside separation blade on the cauldron body 1, is used for further strengthening the sealing washer is at cauldron body axial position, prevents to produce cauldron body axial displacement when opening and close. The external port of the channel 11 is connected with the ventilation pump 5 and the air pressure monitor 7. And closing the kettle cover and locking, opening the air pump 5 and the air pressure monitor 7, inflating the sealing ring inflating ring 23, and tightly attaching the kettle body to the kettle cover at the O-shaped part of the extending part of the sealing ring during inflation so as to achieve the sealing effect and detect the sealing ring by the air pressure monitor 7.
