Abstract
The pressure cooker overflow valve integrated anti-blocking device has two main characteristics: firstly, a cover with a plurality of steam through holes forms a convex structure; secondly, the conical surface part of the seat forms an arch back structure. Obviously, the structure can greatly improve the rigidity of the integrated anti-blocking device and is not easy to deform and damage in use. In addition, compared with other integral type anti-blocking devices with the same surface area, the utility model discloses will seem more pleasing to the eye, smaller and more exquisite.
Description
The utility model relates to a kind ofly can be directly installed on the pressure cooker that uses the steam valve valve rod lower end of the overflowing steam valve integral type bridge breaker that overflows by device seat and the device lid ， And that is formed by connecting by being arranged on internal thread on the device seat.
The device lid of the excessive steam valve integral type bridge breaker of known pressure cooker is the flat thin plate of metal that a slice surface is provided with numerous logical vapour apertures, though the device seat forms taper, but the surface also is provided with numerous logical vapour apertures, therefore, on the whole, the rigidity of this integral type bridge breaker is relatively poor, in use causes deformed damaged easily.
The purpose of this utility model provides the excessive steam valve integral type bridge breaker of the strong pressure cooker of a kind of rigidity.
The solution of above-mentioned purpose is: the device lid with numerous logical vapour apertures forms convex configuration.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structure chart.
Device seat 1 of the present utility model and device lid 2 form integrative-structure by the inclusion of its skirt materials, device seat 1 comprises cylindrical portions may and conical surface part, stretching extension, mold pressing by material are shaped, cylindrical portions may is provided with the internal thread 3 that the same external screw thread that overflows steam valve valve rod lower end matches, for the rigidity of booster seat 1, the conical surface partly can be formed hunchbacked structure; Device lid 2 forms convex configuration by the stretching mold pressing of material, is provided with numerous logical vapour apertures 4 on convex surface.
Device seat and device lid forms the integral type bridge breaker of the back of a bow and convex configuration respectively, and its rigidity obviously can improve greatly, just can not deformed damaged in the use, in addition, with other integral type bridge breaker with identical table area relatively, it is more attractive in appearance, smaller and more exquisite that the utility model will seem.
Claims (2)
1, the excessive steam valve integral type bridge breaker of a kind of pressure cooker is formed by connecting by device seat and device lid, and the device seat has the conical surface and internal thread, it is characterized in that: the device lid 2 with numerous logical vapour apertures 4 forms convex configuration.
2, the excessive steam valve integral type bridge breaker of pressure cooker according to claim 1, it is characterized in that: the conical surface of device seat 1 forms hunchbacked structure.
