The present invention further technical scheme, the radius of the circular port for the spherical barrel diameter three/
One.
The present invention further technical scheme, the flange engaging tooth and the end cap engaging tooth are Multi-layer design,
And the thickness of each layer engaging tooth is gradually thinning from bottom to up.
The present invention further technical scheme, the spherical cylinder is by the hemispherical welded steel of two pieces of upper end opens
Shaping.
The present invention further technical scheme, the number of rotation that the fast beginning lid circumference rotation is closed completely with flange
For 36 °.
Wave absorption cone is provided with immediately below the present invention further technical scheme, the fast beginning lid.
The present invention further technical scheme, the wave absorption cone is the downward cone in summit.
The present invention is will be described in detail below.
Because the engaging tooth of the present invention is designed using multilayer varying pitch, the thickness of each layer engaging tooth is at least gradually become under
It is thin, therefore can improve engagement Transverse Load irrational distribution, and can reduce structural stress concentration, so that the present invention
Fast beginning lid has the advantages that linking intensity height, folding are quick.The underface that the present invention is also covered at the fast beginning, which is provided with, to be shaped as
The downward cone in summit is bored as wave absorption, and the design can preferably reduce the impulsive force peak value suffered by end cap, further lifting
The coupling reliability of container, reduces container end quality.
[beneficial effect]
The present invention compared with prior art, with following beneficial effect：
The pressure vessel fusion varying pitch bolt-connection of the fast beginning lid of multiple tooth varying pitch of the present invention and Tooth-locked Quick Closure end
The design philosophy of lid, so that the lid of fast beginning of the present invention has the advantages that linking intensity height, folding are quick；Secondly, the present invention is adopted
With band cone angle design, the impulsive force peak value suffered by end cap, the coupling reliability of further hoisting container, reduction can be preferably reduced
Container end quality.

Embodiment
With reference to embodiments of the invention, the invention will be further elaborated.
As described in Fig. 1~Fig. 8, the pressure vessel that a kind of multiple tooth varying pitch fast beginning of the invention covers, it includes the fast beginning
Lid and container body, the container body is welded as a whole by spherical cylinder 1 and flange 2, the flange 2 and fast beginning
Lid is using the connection of multiple tooth varying pitch tooth-type；The spherical cylinder upper end opened round mouthful, the flange 2 is cylindrical shape, its lower end
Diameter is equal with the circular port；It is provided with the inside of the flange by spherical cylinder on the inside of support ring 3, the flange in support ring
3 upper ends, which are provided between flange engaging tooth 4, the adjacent flanges engaging tooth, depression neck, and the depression neck
Width is more than the width of the flange engaging tooth；The fast beginning lid periphery is provided with the end cap being engaged with flange engaging tooth 4
Engaging tooth 7, after the end cap engaging tooth 7 is docked with the depression neck on flange, support is moved downwardly to along depression neck
Ring, then fast beginning lid circumference rotation is closed completely with flange；The fast beginning covers Central Symmetry position welding handle 6.Institute
The radius for stating circular port is 1/3rd of the spherical barrel diameter.The flange engaging tooth and end cap engaging tooth are multilayer
Design, and the thickness of each layer engaging tooth is gradually thinning from bottom to up.The spherical cylinder is by the hemispherical of two pieces of upper end opens
Welded steel is molded.
The preferred embodiment of the present invention, the number of rotation that the fast beginning lid circumference rotation is closed completely with flange
For 36 °.The direction of the fast beginning lid circumference rotation is clockwise or counterclockwise.
Wave absorption cone 5 is provided with immediately below the present invention further technical scheme, the fast beginning lid.The wave absorption is bored
The downward cone in summit.
Peak impact ripple is most strong to the percussion of end cap, therefore only effect of the analysis peak impact ripple to end cap：
Can be seen that Fig. 9 by Fig. 9 and Figure 10 is shock wave schematic diagram suffered by band slicing tapered end lid, and Figure 10 is common end
The suffered shock wave schematic diagram of lid.After explosive detonates at center, it is believed that shock wave in atmosphere propagate by constant speed, therefore within the △ t times,
Shock motion is apart from identical, then t1、t2、t3、t4、t5、t6(△ t is differed between each time point) moment shock wave arrives separately at a
Point, b points, c points, d points, e points, f points, are hit in t with slicing tapered end lid as seen from the figure1~t2、t2~t3、t3~t4、t4~
t5、t5~t6Completed in five periods, flat board end cap is hit then in t5~t6Completed in period, and in any △ t
In, the shock wave area with slicing tapered end lid is substantially smaller than flat board end cap, therefore can be preferably with slicing tapered end lid
Reduce the impulsive force peak value suffered by end cap.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferably embodiment, embodiments of the present invention are simultaneously not restricted to the described embodiments, it should be appreciated that people in the art
Member can be designed that a lot of other modification and embodiment, and these modifications and embodiment will fall in principle disclosed in the present application
Within scope and spirit.
