Abstract
The utility model relates to a pressure vessel head for a jacketed pan. The pressure vessel head comprises a head body and further comprises a pressure panel. The upper portion of the head body is a semi-oval plate, the lower portion of the head body is provided with a circle of straight edge around the periphery of the semi-oval plate, the pressure panel surrounds a circle of the inner side of the bottom end of the head body, and the head body and the pressure panel are formed integrally. The upper portion of the pressure vessel head is in a semi-oval shape, and a longitudinal section of the pressure vessel head is a semi-oval curve. The radius of curvature of the curve changes continuously and is free of a shape changing position. Stress distribution of the head is even, and a stress condition of the head is better than that of a butterfly-shaped head. By arranging the circle of straight edge around an oval opening of the lower portion of the head and simultaneously arranging the pressure panel at the bottom end of the head body, overlaying of thermal stress and edge stress is prevented, and the strength is enhanced.
Description
Technical field
The utility model relates to a kind of pressurized container end socket used, relates in particular to a kind of pressure vessel head for jacketed pan.
Background technique
End socket is the main pressure-containing member of pressurized container.It is as the closed end of container, forms a complete seal container with cylindrical body.Traditionally, end socket usually refers to be welded to connect into non-disconnectable container end portion structure with cylindrical body.Under pressure, the size of the stress on the end socket shell wall is all relevant with its pattern, shape with distribution.And at present on the market the shape great majority of end socket be only plate shaped or half elliptic, and stressed comparatively concentrated, perhaps thermal stress and edge stress superpose and cause Seal Head Strength lower.
Summary of the invention
According to the deficiencies in the prior art, the utility model provides a kind of pressurized container end socket used.This Seal Head Strength is high, and quality is good.
According to the deficiencies in the prior art, the technological scheme that the utility model provides is: a kind of pressure vessel head for jacketed pan, comprise end socket main body, described end socket also comprises pressure panels, the top of described end socket main body is the half elliptic plate, the bottom of described end socket main body is with a circle straight flange around half elliptic plate surrounding, and described pressure panels is an inboard circle around the bottom of end socket main body, and described end socket main body and pressure panels are formed in one.
The material of described end socket is iron or stainless steel or aluminium.
The thickness of described end socket main body and the consistency of thickness of pressure panels.
Described pressure panels is ring.
The beneficial effects of the utility model are: the top of having adopted of the present utility model is half elliptic, and its longitudinal section is bar semiellipse curve.The curvature of a curve radius changes continuously, there is no shape sudden change place.Thereby the stress distribution of end socket is more well-balanced, and force-bearing situation is more superior than dished (torispherical) head.Bottom of having adopted end socket of the present utility model is with a circle straight flange around oval mouth, is provided with pressure panels in the end socket main body bottom simultaneously, prevents the stack of thermal stress and edge stress, has increased intensity.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of pressure vessel head for jacketed pan, comprise end socket main body 1, described end socket also comprises pressure panels 2, the top of described end socket main body 1 is the half elliptic plate, the bottom of described end socket main body 1 is with a circle straight flange around half elliptic plate surrounding, and described pressure panels is an inboard circle around the bottom of end socket main body 1, and described end socket main body 1 and pressure panels 2 are formed in one.
The material of described end socket is iron or stainless steel or aluminium.
The consistency of thickness of the thickness of described end socket main body 1 and pressure panels 2.
Described pressure panels 2 is ring.
