Abstract
The utility model relates to a bow-bottom head; the bottom surface of the head is inwards to the inside, i.e. the top is inwards, and the inward geometric shape is in smooth transition; the liquid impacted by vibration can be guided by an arc-shaped surface, flows back into a container, and the head has the advantages of good stress state and small fluid impact; the diameter of the upper circular opening of the bow-bottom head is Di, the bow-bottom head is inwards to form an arc shape, the radius R of a spherical surface on which the arc shape is located is more than or equal to Di, the edge of the bow-bottom head is arc-shaped, and the radius r of the spherical surface on which the arc shape is located is more than or equal to 0.1Di. The bow-bottom head has the advantages of good anti-seismic performance, strong buffering capability, long service life and good inner pressure bearing capability.
Description
Technical field
The utility model relates to end socket used in a kind of pressurized container, especially a kind of end socket with damping, buffering effect, specifically a kind of bow bottom (head).
Background technique
End socket belongs to a kind of of boiler component in the pressurized container.In the end socket manufacturing, that existing end socket is generally is oval, taper or dish, the end socket use that matches with the cylindrical shell of pressurized container.The end socket end face of these several basic stylings is all to lower convexity, in transportation process, because vibrations, the liquid of the carrying in the container can spatter to the top, and the impact strength that end socket is caused is big, and the end socket that experiences hydraulic shock for a long time damages easily, press poor performance in bearing, influence the life-span that end socket uses.Therefore, it is good that the end socket of existing common shape can not reach anti-seismic performance, and buffer function is strong, and long service life is pressed the good requirement of performance in bearing, can not satisfy the needs of prior art.
Summary of the invention
It is good that the purpose of this utility model is that the end socket at existing common shape can not reach anti-seismic performance, and buffer function is strong, and long service life is pressed the good problem of performance in bearing, propose a kind of bow bottom (head) with damping, buffering effect.
The technical solution of the utility model is:
A kind of bow bottom (head), described end socket bottom surface inwardly is a top depression.
Bow bottom (head) of the present utility model diameter of a circle suitable for reading is Di, the bow bottom (head) formation arc that caves inward, the radius R 〉=Di of arc place sphere.
Bow bottom (head) of the present utility model diameter of a circle suitable for reading is Di, and bow bottom (head) edge is an arc, the radius r≤0.1Di of arc place sphere.
The height of bow bottom (head) edge h of the present utility model is 5～25mm.
The beneficial effects of the utility model:
Bow bottom (head) anti-seismic performance of the present utility model is good, and buffer function is strong, and long service life presses performance good in bearing.
Bow bottom (head) geometrical shape transition slyness of the present utility model because the liquid that comes on the jerk can pass through the arc shaped surface water conservancy diversion, along flowing back to internal tank, has the advantage that force-bearing situation is good and fluid impact power is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of bow bottom (head), described end socket bottom surface inwardly is a top depression, the geometrical shape transition slyness that caves inward, because the liquid that comes on the jerk can pass through the arc shaped surface water conservancy diversion, along flowing back to internal tank, has the advantage that force-bearing situation is good and fluid impact power is little.
Bow bottom (head) of the present utility model diameter of a circle suitable for reading is Di, the bow bottom (head) formation arc that caves inward, the radius R 〉=Di of arc place sphere.
Bow bottom (head) of the present utility model diameter of a circle suitable for reading is Di, and bow bottom (head) edge is an arc, the radius r≤0.1Di of arc place sphere.
The height of bow bottom (head) edge h of the present utility model is 5～25mm.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (4)
1. a bow bottom (head) is characterized in that described end socket bottom surface inwardly is a top depression.
