Abstract
A pressure vessel with a quick open cover comprises a tank body and the quick open cover mounted at the end port of the tank body. The vessel is characterized in that the quick open cover includes connecting flanges and a spherical-cap end cover welded on the connecting flanges, and the central angle corresponding to the arc length of the axial cross section of the spherical-cap end cover is further designed within the range of 55-70DEG. Compared to the prior art, the pressure vessel with the quick open cover has the advantages that an oval end cover is replaced by the spherical-cap end cover,so as to reduce the occupied space of the end cover and effectively save energy consumption; and a tangential drawing force is exerted on the spherical-cap end cover and the connecting flanges whichare welded together, so as to achieve firmer connection, higher integral intensity and low possibility of damage.
Description
Technical field
The utility model relates to a kind of pressurized container, relates in particular to a kind of pressurized container with quick-actuating closure, as sulfurizing pot, fixed pot, retort, autoclave etc.
Background technique
Existing quick-actuating closure pressurized container, as sulfurizing pot, fixed pot, retort, autoclave etc., no matter be horizontal or vertical, as shown in Figure 3, consist essentially of tank body 1a and be located at the quick-actuating closure 2a of tank body 1a port, the ellipsoidal head of quick-actuating closure 2a employing in the past 22a is welded on the flange 21a and makes, the cross section of ellipsoidal head 22a is an elliptic arc, ellipsoidal head 22a end has the cylindrical body 23a parallel substantially with tank body 1a, this cylindrical body 23a is welded on the flange 21a in the fillet welding mode, have following deficiency: at first, the end socket inner space of quick-actuating closure is bigger, will certainly need more heat transfer to fill; Secondly, the weld joint of ellipsoidal head is because of being subjected to shearing force F
1With shearing force F
2Effect and make the weld internal stress bigger, be easy to damage to leak.
The model utility content
Technical problem to be solved in the utility model be provide a kind of end socket inner space of quick-actuating closure less at the above-mentioned state of the art, the good quick-actuating closure pressurized container of the stressed property of end socket and adpting flange place.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of quick-actuating closure pressurized container, comprise tank body and be located at the quick-actuating closure of tank body port, it is characterized in that described quick-actuating closure comprises adpting flange and is welded in spherical end socket on the adpting flange.
As preferably, the pairing central angle of the arc length of the shaft section of described spherical end socket is 55～70 °.
Perhaps the ratio of the spherical radius of described spherical end socket and adpting flange diameter is 0.7～1.2.
The port of described spherical end socket tangentially is welded on the described adpting flange in the mode of butt welding.Like this, the stress of weld is mainly tangential tensile force, so bulk strength increases.
Compared with prior art, advantage of the present utility model is: spherical end socket replaces ellipsoidal head, making the end socket of quick-actuating closure take up space reduces, effectively energy saving consumption, after spherical end socket and the adpting flange welding, what be subjected to is the effect of tangential tensile force, and the tensile strength of material is more much bigger than shear strength, thereby make that connection is more firm, bulk strength increases, and is not fragile; Can be widely used on sulfurizing pot, fixed pot, retort, the autoclave equal pressure container.

Fig. 2 is a quick-actuating closure amplification view among Fig. 2.
Fig. 3 is a construction of pressure vessel schematic representation of the prior art.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, pressurized container in the present embodiment is a sulfurizing pot, comprise tank body 1 and be located at the quick-actuating closure 2 of tank body 1 port, tank body 1 rearward end is provided with blower fan 3, the bottom is provided with pedestal 4, quick-actuating closure 2 comprises adpting flange 21 and is welded in spherical end socket 22 on the adpting flange 21,55～70 ° of the pairing central angle θ of the arc length of the shaft section of this spherical end socket, perhaps the ratio of the spherical radius of spherical end socket and adpting flange diameter is 0.7～1.2, the port of spherical end socket 22 tangentially is welded on the adpting flange 21 in the mode of butt welding, and the groove penetration weld has been adopted in butt welding.So that weld is subjected to is tangential tensile force F
3With tensile force F
4Effect, make to connect more firmly, bulk strength increases.
Claims (4)
