Among the figure: 1 is weight, and 2 is thimble, and 3 is shell, and 4 is inner casing, and 5 is mass, and 6 is air-vent, and 7 is catching groove, and 8 is transition face, and 9 is shortwall, and 10 is chimb.
Concrete embodiment
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
As shown in the figure, limiting valve of pressure cooker of the present utility model comprises weight 1 and is installed on thimble 2 in the weight 1, and weight 1 is made up of the mass 5 that concrete curing thing or pottery etc. are set in shell 3, inner casing 4 and the cavity that constitutes between shell 3 and inner casing 4.Thimble 2 is fixed in the central authorities at inner casing 4 tops.
Described inner casing 4 is cylindric, and the top is provided with air-vent 6, and the bottom of cylinder stretches out into a transition face 8, and transition face 8 extends upward to a shortwall 9 again, and the top of shortwall 9 is provided with the chimb 10 of centrifugal direction.
Described shell 3 is the cylindric of hollow, and the top of shell 3 is provided with air-vent 6, and the inwall lower end of cylinder is provided with catching groove 7.
The cavity that shell 3 and inner casing 4 are formed can be a numerous embodiments, and shown in Fig. 2～5: the outside of the outward extending transition face 8 of inner casing 4 is buckled on the catching groove 7 of above-mentioned shell 3.Or the chimb 10 that inner casing 4 shortwalls 9 tops are provided with is buckled on the catching groove 7 of above-mentioned shell 3.
Certainly, the catching groove 7 of shell 3 can be that the clasp of shell 3 inwall lower ends constitutes (seeing Fig. 2 and Fig. 5), also can be to establish a groove to constitute (seeing Fig. 3 and Fig. 4) in the inwall lower end.
The air-vent 6 at the air-vent 6 at shell 3 tops and inner casing 4 tops connects mutually, constitutes the air-vent 6 of weight 1 integral body.
