Abstract
A sealing structure for a pressure-resistant tank comprises a sealing head and a cylinder body. The lower portion of the sealing head is inserted into the cylinder body and tightly attached to the inner wall of the cylinder body; at least one sealing ring is embedded at the attaching position; the cylinder body is tightly fixed to the sealing head through screw nails; a rotatable opening screw nail is arranged inside the sealing head in longitudinal penetrating manner; when the bottom portion of the opening screw nail is abutted to the end surface of the cylinder body, the distance that the top portion of the opening screw nail is higher than the top portion of the sealing head is larger than the length that the lower portion of the sealing head is embedded into the cylinder body; and the diameter of the top portion of the sealing head is the same with the outer diameter of the cylinder body. A flange sealing head of the sealing structure for the pressure-resistant tank is connected with the cylinder body through set screw nails, the weight of the flange structure and the weight of the whole structure of the pressure-resistant tank are both decreased, and the flange sealing head needs no welding with the cylinder body, thereby effectively avoiding problems of deformation and stress concentration caused by welding. By adopting the set screw nails and the opening screw nail, the sealing structure for the pressure-resistant tank can be assembled and disassembled extremely conveniently, and has excellent sealing performance under deep ocean pressure.
Description
Technical field
The utility model belongs to offshore engineering equipment, is specifically related to be applied to the device of underwater installations such as bathyscaphe, submarine.
Background technique
Autoclave is to go up modal a kind of device such as equipments such as submersibles in the ocean engineering.As shown in Figure 1, it generally is made up of the cylindrical barrel body 102 of centre and the end socket 101 of two ends (or an end).Can arrange some instrument and equipments in the cylindrical shell 102, opening is generally arranged on the end socket 101, be used for electrical connector.The inner normal pressure that keeps of total, the outside is subjected to the deep sea pressure effect.End socket 101 is a key structure of guaranteeing the autoclave sealing with the sealing configuration (G portion) of 102 sections of cylindrical shells.Conventional sealing configuration all adopts 103 sealings of O RunddichtringO, flange ways of connecting.
Fig. 2 shows the conventional sealing configuration of several existing autoclaves.See Fig. 2, according to the difference of seal ring 103 present positions, conventional sealing configuration has following several form: A is end face seal, and B is radial seal, and C is end face and radial seal (being this structure among Fig. 1), and D is a conical surface seal.Because these sealing configurations all connect by flange, and two kinds of Placements are arranged between flange on the end socket 101 and end socket 101 housings: a kind of is welding, but welding can cause malformation and stress raisers; Another kind is that flange and the housing on the end socket 101 is to be processed by a bar or thick walled tube integral body, and this method waste of material is more serious.And because flange is bigger, under big degree of depth seawater pressure, its structural stress complexity, structure weight is obviously bigger than normal.And the weight requirement is strict on bathyscaphe.
The model utility content
Adopt the above-mentioned defective of joint seal of flanges structure existence at existing autoclave, the claimant improves through research, the sealing configuration of another kind of autoclave is provided, its flange arrangement weight and overall structure weight reduce greatly, and do not need welding, thereby distortion and the problem of stress concentration of effectively having avoided welded structure to bring.
The technical solution of the utility model is as follows:
A kind of sealing configuration of autoclave, it is characterized in that: comprise end socket and cylindrical shell, the bottom of end socket embeds in the cylindrical shell, and fit tightly with the inwall of cylindrical shell, the joint place is embedded with at least one seal ring, and is fastening by screw between cylindrical shell and the end socket, is provided with rotatable unlatching screw in vertically running through in the end socket, when the bottom of unlatching screw and the end face butt of cylindrical shell, open the screw top and be higher than the distance at end socket top greater than the length in the described end socket bottom embedding cylindrical shell.
Its further technological scheme is: the diameter at described end socket top equates with the external diameter of cylindrical shell.
Useful technique effect of the present utility model is:
Flange end socket of the present utility model is connected with cylindrical shell by fastening screw trip bolt, and flange arrangement weight and overall structure weight all reduce greatly, and does not need welding, thus distortion and the problem of stress concentration of effectively having avoided welding to bring.The utility model is simple in structure, there is not the flange edge of protrusion, by fastening screw trip bolt and open screw installation or removal very easily, and under deep sea pressure, have good sealability, be particularly useful for minor diameter, thin-walled, can't use the autoclave of end-face seal ring.
Description of drawings
Fig. 1 is the sectional view of existing autoclave.
Fig. 2 is the sectional view of the sealing configuration of existing autoclave, comprising the enlarged view of G portion among Fig. 1.
Fig. 3 is a sectional view of the present utility model.
Fig. 4 is the enlarged view of H portion among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 3 is the sectional view that adopts autoclave of the present utility model, and it is made up of the cylindrical shell 202 of column and the end socket 201 of upper end.Can arrange instrument and equipment in the cylindrical shell 202, have opening 206 on the end socket 201 and be used to be provided with electrical connector.Fig. 4 is the enlarged view of H portion among Fig. 3, shows sealing configuration of the present utility model.As shown in Figure 4, the sealing structure comprises end socket 201 and the cylindrical shell 202 that has little flange, and both process at equal integral body, need not welding, has avoided the adverse effect of welding to autoclave.The bottom of end socket 201 embeds in the cylindrical shell 202, and fits tightly with the inwall of cylindrical shell 202, and the end socket 201 of joint place is embedded with at least one seal ring 203, among the figure is to realize radial seals by two O RunddichtringOs 203, and reliability is higher.The diameter at end socket 201 tops is identical with the external diameter size of cylindrical shell 202, and material avoids waste.Be connected and fixed by fastening screw trip bolt 204 between cylindrical shell 202 and the end socket 201, carry out spacing.End socket 201 runs through in vertically and is provided with rotatable unlatching screw 205, and the bottom of opening screw 205 is during with the end face butt of cylindrical shell 202, and the top of opening screw 205 exceeds the distance at end socket 201 tops greater than the length in the end socket 201 bottoms embedding cylindrical shell.Earlier fastening screw trip bolt 204 is unloaded during dismounting, screwing unlatching screw 205 then moves down its relative end socket 201, opening the lower end of screw 205 backs down cylindrical shell 202, during length when the distance of backing down embeds cylindrical shell greater than end socket 201 bottoms in, end socket 201 is separated with cylindrical shell 202, it is very easy to dismantle, and is convenient to the maintenance of instrument and equipment in the autoclave.End socket 201 is seal-installed on step on the cylindrical shell 202 with above-mentioned opposite.
