Abstract
The invention relates to the field of pressure cookers, in particular to a pressure limiting valve for a pressure cooker. The pressure limiting valve for the pressure cooker comprises a heavy punch and a thimble arranged in the heavy punch, wherein the heavy punch is a cavity consisting of a shell and an inner shell; and the cavity is provided with fillers. The pressure limiting valve for the pressure cooker has the advantages of simple structure, environmental friendliness, low price and the like.
Description
Technical field
The present invention relates to the pressure cooker field, particularly relate to a kind of limiting valve of pressure cooker.
Background technology
Existing limiting valve of pressure cooker is used for the pressure in the pressure cooker control pot, pressure is not leaked play one to make the food can well-done fast effect, by the time food when well-done, by the mode of opening pressure limiting valve the pressure in the pressure cooker is discharged outside the pot, country has announced an improvement structure that denomination of invention is a limiting valve of pressure cooker, application number is: 03247947.6, its structure is: comprise valve body, place the jump ring of valve hole bottom, sleeve is in the spool of valve hole bottom, clog the thimble of valve core through hole, pressure limiting valve seat and anti-blocking seat are formed, valve body places in the cavity of a handle, be right after an end of thimble in the cavity of this handle, the other end of thimble stretches into valve hole and fills in the upper end of valve core through hole, the handle sleeve is in the pressure limiting valve seat, it inserts pressure limiting valve seat lower end partly and has several high breach and the low breach that is differential arrangement, is provided with in the pressure limiting valve seat and described high breach and the suitable projection of low breach.Said structure has the following disadvantages: 1, not enough environmental protection; 2, material is more; 3, its cost of manufacture is higher, inadequately material benefit.
Summary of the invention
The objective of the invention is to improve above-mentioned deficiency provides that a kind of the cost of material is low, environmental protection, simple in structure, durable, cheap limiting valve of pressure cooker.
For realizing purpose of the present invention, described limiting valve of pressure cooker comprises weight and is installed on thimble in the weight, and the cavity that described weight is made up of shell and inner casing is provided with the mass of configuration in the cavity.
Described shell is the cylindric of hollow, and the top of shell is provided with air-vent, and the inwall lower end of cylinder is provided with catching groove.
Described inner casing is cylindric, and thimble is fixed in the central authorities at inner casing top, and the top is provided with air-vent, and the bottom of cylinder stretches out into a transition face, and described outward extending transition face extends upward to a shortwall again, and the shortwall top is provided with the chimb of centrifugal direction.
Described shell catching groove is buckled in the outer edge of excessive face or is buckled on the chimb of excessive face.
Described mass is concrete curing thing or pottery.
Beneficial effect of the present invention: it causes weight and makes hollow, in fill out cheap ceramic mass, reach and produce purpose simple, cheap, environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of second embodiment of Fig. 2;
Fig. 4 is the structural representation of the 3rd embodiment of Fig. 2;
Fig. 5 is the structural representation of the 4th embodiment of Fig. 2.
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 present invention is done detailed explanation:
As shown in the figure, limiting valve of pressure cooker of the present invention 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.
