Abstract
The utility model relates to an explosion-proof sealing ring device for a pressure cooker, which is formed by matching a sealing ring with a cooker cover and a cooker body, wherein the inner wall of the cooker cover is fixedly provided with a clamping ring. After the sealing ring is put in the clamping ring and the cooker cover is covered on the cooker body, a gap delta X is formed between the clamping ring and the cooker body. In normal use, the sealing ring performs the sealing function. After the pressure in a pressure cooker exceeds the maximal working pressure, the lower sealing end of the sealing ring is extruded out from the gap delta X, therefore, the decompression is realized. Because the decompression position of the sealing device is positioned in the gap of the entire circumference, the compression is uniform, and the pressure cooker is much safer and more reliable. The cooker cover dose not need to be provided with a pressure relief opening, and the integrality and the entire shape of the cooker cover are reserved.
Description
The utility model relates to a kind of explosion-protection equipment of pressure cooker, and particularly a kind of sealing ring cooperates with pot cover, pot body, both seals, and has the explosive-proof sealed coil apparatus of the pressure cooker of explosion prevention function again.
The patent No. 95234112.3 " the not quick-fried safe pressure cooker of a kind of new structure " is exactly to have through hole in pot body, pot cover outer rim on the relevant position, after pot inner pressure oversteps the extreme limit operating pressure, sealing ring is just extruded the purpose that reaches pressure release from the through hole, though the method energy pressure release, but pressure relief opening is limited, and the position limit is dead, and the overall appearance of the influence pot that on pot, punches.
The purpose of this utility model is to provide a kind of explosive-proof sealed coil apparatus of pressure cooker, can seal and have explosion prevention function, and the sealing ring pressure release is even, uses safer, reliable.
The utility model is achieved in that the explosive-proof sealed coil apparatus of pressure cooker, match and form with pot cover, pot body by sealing ring, and also be fixed with collar on the described pot cover inwall, sealing ring is put into collar, pot cover is combined on pot body between back collar and pot body a gap △ X.
Fig. 1. structural representation of the present utility model.
Fig. 2. the partial enlarged drawing of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
The cross section of card figure (3) is L shaped or ㄈ shape, and spot welding is fixed on the inwall of pot cover (1).Sealing ring (2) cross section is
Shape, the outer side edges of upper and lower side have an annulus that protrudes, and the sealed end wall thickness is B, stretch into seal length H=3～10 millimeter of a pot body (4), and make the upper surface of a pot body (4) pot tooth and the gap △ X=2～4B between collar (3) lower surface.
As long as sealing ring (2) is put into collar (3), then pot cover (1) is covered on pot body (4) during use, behind the pressure, the lower seal end of sealing ring (2) just is extruded from △ X gap location, thereby reaches the pressure release purpose if pot inner pressure oversteps the extreme limit.
The utility model is compared with prior art: pressure relief opening of the prior art only is confined to several points, therefore Pressurized is inhomogeneous. And the pressure release position of this gasket set is in the gap of whole circumference, so pressurized is even, Use safer, reliable. Now do not need to open pressure relief opening at pot cover, kept the complete and overall appearance of pot cover.
Claims (3)
1. the explosive-proof sealed coil apparatus of a pressure cooker, match and form with pot cover, pot body by sealing ring, it is characterized in that also being fixed with collar (3) on described pot cover (1) inwall, sealing ring (2) is put in people's collar (3), after pot cover (1) is combined on pot body (4), between collar (3) and pot body (4) a gap △ X is arranged.
2. device according to claim 1, the cross section that it is characterized in that card figure (3) is L shaped or ㄈ shape, spot welding is fixed on the inwall of pot cover (1).
3. device according to claim 1 is characterized in that sealing ring (2) cross section is
Shape, the outer side edges of upper and lower side have an annulus that protrudes, and the sealed end wall thickness is B, stretch into seal length H=3～10 millimeter of a pot body (4), the upper surface of pot body (4) pot tooth and the gap △ X=2～4B between collar (3) lower surface.
