Include the rupture pressure disc of the mounting portion and inside in outside, wherein the lateral area setting indentation of rupture pressure disc, and under normal conditions some
Indentation is enclosed construction, and when burst disk explosion, indentation area defined integrally flies out, and may be damaged to human body, thus
There are hidden danger for secure context, and other indentations use semi-closed structure, although making preventing for the region and outside inside indentation
There are coupling parts for quick-fried film, but structure is single, it is difficult to the case where thoroughly indentation area defined being avoided to fly out, it is difficult to thoroughly
It eliminates safe hidden trouble.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiencies existing in the prior art, and provide a kind of structure design conjunction
The case where reason, the double C word structures of safe new type explosion proof, the explosion-proof diaphragm area that can be surrounded to avoid indentation flies out.
The technical scheme in the invention for solving the above technical problem is：The double C word structures of the new type explosion proof, including it is explosion-proof
Piece, there are one grooves for the integration stamped swaging slabbing structure of the burst disk and in the middle tool, it is characterised in that：The groove
It is interior that there is outer ring indentation, outer ring indentation to be arranged and be formed enclosed construction along the edge of the groove, have in enclosed construction double
Two " C " font indentations of " C " font indentation, bis- " C " font indentations are disposed opposite to each other and position has a coherent portion therebetween,
Described two " C " font indentations are connected to outer ring indentation, and the outer in the radial direction of the burst disk central shaft forms peace
Dress portion has straight mounting surface on the mounting portion.Burst disk is integration stamped molded, and processing is very simple, and indentation is divided into
Outer ring indentation and bis- " C " font indentations, when burst disk explosion, explosion, due to the presence of bis- " C " font indentations, subtracts at indentation
The pressure that light outer ring indentation is subject in explosion, causes to damage, use is safer, burst disk due to without whole fly out
It is installed by its mounting portion, and mounting portion is thicker, increases bonding strength.
The setting track of outer ring indentation described in the utility model is located at the outer of a cyclic structure or polygonized structure
Zhou Shang.
The setting track of outer ring indentation described in the utility model is located in a cyclic structure.This indentation is more continuous,
The pressure value that can be born is easy to calculate, convenient for being adjusted according to pressure demand.
The shape of groove described in the utility model is corresponding with the shape of burst disk.
Outer ring indentation described in the utility model burst disk opposite with bis- " C " font indentations is in inner concavity, and its cross sectional shape
It is semicircle trapezoidal or rectangular.
The cross sectional shape of outer ring indentation described in the utility model and bis- " C " font indentations is trapezoidal.
The utility model compared with prior art, has the following advantages and effect：Burst disk is integration stamped molded, indentation
For enclosed construction, processing is very simple, after popping at indentation, due to the presence of bis- " C " font indentations, alleviates outer ring indentation
The pressure being subject in explosion causes to damage due to without whole fly out, and use is safer, and burst disk passes through its mounting portion
It is installed, and mounting portion is thicker, increases bonding strength.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the double C word structures of new type explosion proof in the utility model embodiment.
