Abstract
The utility model provides a high pressure sealing device for a container, comprising a clip, a sealing ring, a connecting stud, an end socket, and the end part of a cylinder. The high pressure sealing device for a container is characterized in that (1) the pitch angle alpha of the side face of the ring slot of the clip is 8 to 15 DEG, and the corner radius R of the side face and the bottom face of the ring slot is 10 to 55 mm; (2) the pitch angle beta of the sealing face of the sealing ring is 8 to 30 DEG, and the outside face of the sealing ring is provided with a bulge ring. The utility model has the advantages of simple structure, high reliability, convenient assembly and disassembly and wide range of application. The high pressure sealing device for a container is especially suitable for the industry of artificial crystal and a petrifaction system whose major diameter is more than or equal to phi 400 mm, high temperature is less than or equal to 500 centi degrees, and high voltage is more than or equal to 100 mpa.
Description
The utility model relates to a kind of seal arrangement that is used for gas, liquid medium, is specially adapted to bear in synthetic quartz industry and the petrochemical system major diameter (internal diameter 〉=φ 400mm) ultrahigh pressure (〉=100MPa) container of high temperature (≤500 ℃).
At present, the high-pressure bottle that in synthetic quartz industry and petrochemical system, uses, its seal arrangement mostly adopts the bipyramid ring to make seal element, bear thrust load with kingbolt, but for the major diameter (ultrahigh pressure of internal diameter 〉=400mm) (〉=100MPa) container, because its axial force is very big, therefore the kingbolt diameter that needs is big, quantity is many, not only structurally be restricted like this, and using, operating aspect is also extremely difficult, and is same, and the bipyramid ring is if will be applicable to ultrahigh pressure (〉=100MPa) operating mode, then must strengthen its cross-section size, this not only needs to increase pretightening force, brings difficulty to initial sealing, and this structure also is difficult to realize on the spheroid end socket that matches with it.
At the characteristics of prior art, it is a kind of easy to manufacture that the purpose of this utility model is to provide, and sealing is reliable, simple load and unload sealing device for high-pressure container.
The purpose of this utility model is to realize by the seal arrangement that designs a kind of high-pressure bottle of being made up of clip, seal ring, connection double-screw bolt, end socket and cylindrical shell end, it is characterized in that: (1) clip annular groove side oblique angle α is 8 to 15 degree, the knuckle radius R of annular groove side and bottom surface is 10 to 15mm, this clip replaces kingbolt to bear thrust load, not only can not be subjected to the restriction of structure, and use and operating all very convenient; (2) seal ring seal face angle of inclination beta is 8 to 30 degree, and there is a bulge loop in the seal ring outside.The sealing ring replaces existing seal ring, not only in light weight, good sealing effect, and initial sealing is easy, and mounting or dismounting are convenient.
Below in conjunction with accompanying drawing the utility model and embodiment are elaborated.
Fig. 1 is plan view of the present utility model and partial sectional view.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a clip partial enlarged drawing of the present utility model.
Fig. 4 is a seal ring master sectional view of the present utility model.
Referring to Fig. 1-Fig. 4: clip of the present utility model (8) be shaped as the three lobe annulus that the end face angle is 120 degree, every lobe clip two ends all have and evenly have two connecting hole on flange, the flange, this hole be connected double-screw bolt (2) and be complementary, it is trapezoidal annular groove that clip inner side surface middle part has a radial cross section.Annular groove side oblique angle α is 8 to 15 degree, this practicality example is got 10 degree (425 ℃ of these autoclave design temperatures in φ 400mm synthetic crystal autoclave, design pressure 150MPa), side and bottom surface are arc transition, its knuckle radius R is 10 to 15mm, and present embodiment is got 13mm, and every lobe clip upper-end surface evenly has two tapped blind holes (6), use with the lifting screw fit in this hole, is convenient to the handling in the clip cargo handling process.End socket (7) top is the spherical crown shape, there is a boss at the middle part, evenly have 3 holes (4) that match with a screw on the boss, one flange is arranged at the bottom, flange one side (promptly) is the conical surface, the oblique angle, side of this conical surface oblique angle and clip annular groove is complementary, another side (promptly) is the plane, have a positioning hole that matches with locating stud (12) on the plane, end socket inside is a cavity, cavity end face center has a through hole (11), this upper end, hole joins with pressure transducer (1), cavity side is the inclined-plane, the sealing surface oblique angle of this inclined-plane and seal ring is complementary, the outer side surface middle part of seal ring (9) (referring to Fig. 4) has bulge loop, on, the bottom is a sealing surface, sealing face oblique angle β is 8-30 degree (present embodiment is got 14 degree), cylindrical shell (10) inner chamber upper end-hole is the inclined-plane, the lower sealing surface oblique angle of this inclined-plane and seal ring is complementary, there is a flange outside of cylindrical shell upper end, lug upper surface is the plane, have on the plane one with the end socket positioning hole corresponding and positioning hole that be complementary with locating stud (12), the flange lower surface is the inclined-plane, the downside of this inclined-plane and clip annular groove coupling has a scrobicular ring that matches with seal ring outside bulge loop diameter around the cylindrical shell upper end-hole.
Clip (8) and seal ring (9) material selection chromium nickel molybdenum-vanadium steel (as are selected 22Gr for use
2Ni
4The MOV steel), have annular groove on the sealing surface of seal ring, annular groove is embedded with soft packing (as filamentary silver, copper or aluminium) present embodiment and is embedded with the filamentary silver of φ 1.5.
During assembling, earlier seal ring (9) level is inserted in the upper end-hole of cylindrical shell (10), again thereon with end socket (7) lifting, make on the end socket positioning hole be installed in cylindrical shell on locating stud (12) in the positioning hole cooperate, thereby make the end socket location, lift three lobe clips (8) then respectively, two sides that make the clip annular groove cooperate with inclined-plane on cylindrical shell and the end socket respectively, connecting double-screw bolt (2) with 6 again penetrates in the attachment hole of clip, respectively 12 packing rings (5) and 12 nuts (3) are twisted on double-screw bolt, tighten each nut at last, three lobe clips are shunk to the center, and end socket and cylindrical shell are linked together, simultaneously the also stressed generation resiliently deformable of seal ring, the side of its sealing surface and end socket and cylindrical shell closely cooperates, and the cavity in the high-pressure bottle is sealed.
During dismounting, unscrew clip earlier and hang out, be screwed on the end socket with playing screw then
During dismounting, unscrew the nut on the clip connected double-screw bolt earlier, unload lower nut, packing ring and connect double-screw bolt, again three lobe clips are hung out, used screw to be screwed into top lifting screw hole (4) on the end socket then, end socket is separated with seal ring or cylindrical shell, with boom hoisting end socket is hung away again, unload seal ring at last; Bulge loop with instrument sled seal ring.Seal ring is separated with end socket or cylindrical shell, thereby finished whole dismantlement work.
Seal ring of the present utility model (9) can with the supporting use of above-mentioned clip, can be used as series product and the supporting use of other securing means again.
The utility model is used for high temperature, high-pressure bottle, the experiment proved that, have simple in structure, sealing is reliable, mounting or dismounting are convenient, the advantage of widely applicable (not receptor structural limitations) is specially adapted to high temperature (≤500 ℃), the high pressure (〉=100MPa) sealing of container of synthetic quartz industry and petrochemical system.
