Abstract
The utility model relates to a steel cylinder, in particular to a refillable steel cylinder structure. The refillable steel cylinder structure comprises a cylinder body, a left sealing head, a right sealing head, a large flange, valves and ducts connected with the valves, wherein the left sealing head and the right sealing head are arranged at two ends of the cylinder body; a large protective cover is arranged outside the left sealing head, and the valves are arranged on the left sealing head, and positioned in the large protective cover; a small protective cover is arranged outside the right sealing head; the large flange is arranged on the left sealing head and positioned in the large protective cover; a blind flange is arranged on the large flange; and the two valves are fixed on the blind flange through two valve seat flanges respectively. According to the utility model, a large perforated structure is adopted on the left sealing head, and valve seats of the valves and ducts are not directly welded on the left sealing head while connected with the flange welded on the left sealing head in the form of flange, so that when the valve seats of the valves are damaged, the blind flange is not required to be replaced, while the valve seat flanges are directly replaced only, as a result, the processing is convenient, and the cost is lowered.
Description
Technical field
The utility model relates to a kind of steel cylinder, but particularly a kind of steel cylinder structure of repeated charging.
Background technique
But the steel cylinder of repeated charging is a kind of pressurized container for accumulating liquid gas, liquid chlorine, liquefied ammonia etc.Chinese utility model patent as application number 201120156224.3, applying date 2011-05-13 relates to a kind of high-pure gas stainless steel welded gas cylinder; mainly comprise cylindrical shell, left end socket, right end socket, valve and large flange; the two ends of cylindrical shell are provided with left end socket and right end socket; left end socket is provided with large safety cover outward; left end socket is provided with valve, and valve is positioned at large safety cover, and right end socket is provided with little safety cover outward; right end socket is provided with large flange, and large flange is positioned at little safety cover.Yet the left and right end socket of existing steel cylinder does not have the large opening structure, and inside can't be cleaned out, and simultaneously, valve seat is non-dismountable, is difficult for when therefore damaging changing.
The model utility content
The utility model does not have the large opening structure for the left and right end socket of existing steel cylinder, and inside can't be cleaned out, the non-dismountable so not easily changeable technological deficiency when damaging of valve seat, but a kind of steel cylinder structure of repeated charging is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
But a kind of steel cylinder structure of repeated charging; comprise cylindrical shell, left end socket, right end socket, large flange, valve and the conduit that is connected with valve; the two ends of cylindrical shell are provided with left end socket and right end socket; left end socket is provided with large safety cover outward; left end socket is provided with valve; valve is positioned at large safety cover; right end socket is provided with little safety cover outward; described left end socket is provided with large flange; large flange is positioned at large safety cover; large flange is provided with blind flange, and described valve has two, and two valves are fixed on blind flange by two valve seat flanges respectively.Adopt the large opening structure on its end socket, valve seat and the conduit of valve directly are not welded on end socket, but are connected with flange on being welded in end socket with the form of flange.Need not change blind flange after the valve seat damage of valve, easy to process as long as directly change the valve seat flange, cost.
As preferably, be arranged at intervals with at least two steel rings on cylinder body outer wall.The guard circle of existing steel cylinder is large with the easy aging loss of rubber ring, will again change during the date to the third pary certification of steel cylinder, and the guard circle that the utility model adopts channel-section steel to do is durable in use.
As preferably, the joint with left end socket and right end socket on cylinder inboard wall is respectively equipped with grommet.Grommet plays backing plate, burns when preventing from welding, and plays connection function during assembling.
As preferably, described right end socket is provided with two obturating plugs, and easy fusing alloy plug seals obturating plug.Easy fusing alloy plug can be also plug screw.
As preferably, described valve seat flange is connected with blind flange by double-screw bolt.
The beneficial effects of the utility model are: but the cleaning of the steel cylinder inside configuration of repeated charging of the present utility model is convenient, clean, the valve seat flange is detachable, saves substantial contribution, avoid waste, and remarkable in economical benefits.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure: 1, obturating plug, 2, easy fusing alloy plug, 3, little safety cover, 4, right end socket, 5, grommet, 6, steel ring, 7, cylindrical shell, 8, conduit, 9, left end socket, 10, large safety cover, 11, large flange, 12, blind flange, 13, valve, 14, the valve seat flange.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Should be appreciated that enforcement of the present utility model is not limited to the following examples, any pro forma accommodation and/or change that the utility model is made all will fall into the utility model protection domain.
Embodiment:
But a kind of steel cylinder structure of repeated charging comprises cylindrical shell 7, left end socket 9, right end socket 4, large flange 11, valve 13 and the conduit 8 that is connected with valve.The two ends of cylindrical shell are provided with left end socket 9 and right end socket 4; left end socket is provided with large safety cover 10 outward; left end socket is provided with valve 13; weld with large flange 11 after left head opening; valve 13 and large flange 11 are positioned at large safety cover; on large flange, blind flange 12 is installed, valve 13 has two, and two valves are fixed on blind flange by two valve seat flanges 14 respectively.The valve seat flange is connected with blind flange by double-screw bolt, and therefore the valve seat flange on left end socket is detachable, can change during damage.Right end socket is provided with little safety cover 3 and 1, two obturating plug 1 of two obturating plugs outward and is welded on right end socket and is positioned at little safety cover 3 inside, adopts easy fusing alloy plug 2 that obturating plug is sealed.
