Abstract
The utility model relates to a belong to super high pressure vessel design, manufacturing field, in particular to a seal structure for superhigh pressure barrel is connected, this seal structure connect two barrels, and this seal structure includes two way seal ring, clamp and stud, the two way seal ring is arranged in between two sections barrels, adopts the clamp taut and fixed through stud with two sections barrels, sections two, the conical surface of barrel terminal surfaces compresses tightly with the both sides conical surface of two way seal ring to reach sealed effect. The utility model provides a guarantee that sealed reliable, the durable barrel that will be originally in barrel junction is divided into two sections or two sections with the manufacturing a seal structure for superhigh pressure barrel is connected that comes up.
Description
Technical field
This utility model relates to belonging to ultrahigh pressure vessel design, manufacture field, particularly to a kind of sealing structure connected for supertension cylinder.
Background technology
When the length of cylinder is more than 20 meters, overall processing has following difficult point: one, in hole machined process, the long easy brill of workpiece is inclined; Two, the axiality of inside and outside circle not easily meets; Three, workpiece is overweight, slightly adds weight about 50 tons for this, and workpiece all exists very big difficulty in the circulation of inter process, processing etc. for general processing producer, for instance: just slightly looking for not when turning or brill endoporus, workpiece will produce violent vibrations; Four, transport, when Workpiece length is more than 20 meters, highway transportation there is also very big difficulty, and cost of transportation will increase substantially. So in general, more piece manufacture is generally all taked to process when the length of cylinder is long.
Utility model content
The purpose of this utility model be in that to overcome above-mentioned prior art provides a kind of ensure cylinder junction seal reliable, durable the cylinder being originally is divided into two joints or two joints above come processing and manufacturing be used for the sealing structure that supertension cylinder connects.
The technical solution of the utility model is achieved in that a kind of sealing structure connected for supertension cylinder, this sealing structure connects two cylinders, this sealing structure includes two-way sealing ring, clip and studs, described two-way sealing ring is placed between two joint cylinders, adopt clip to save cylinder by two to strain and fixed by studs, the described conical surface of two joint body end surface compresses with the both sides conical surface of two-way sealing ring, to reach the effect sealed.
The endoporus of described barrel end is the conical surface of 9 ��, and cylinder internal diameter d3 scope is between 100mm-500mm.
The two ends cylindrical of described two-way sealing ring is 8 �� of conical surfaces, and its internal diameter d1 scope is between 100mm-480mm.
Clamping hoop type structure is adopted to be connected between described two-way sealing ring and cylinder.
Described two-way sealing ring adopts 42CrMo, described cylinder and clip to adopt PCrNi3MoVA material to make.
The hardness of the material of described two-way sealing ring is not more than the hardness of described cylinder material.
The good effect that the technical solution of the utility model produces is as follows: the cylinder being originally is divided into more than two joints or two joints to carry out processing and manufacturing by sealing structure of the present utility model, this utility model is exactly a kind of sealing structure for connecting two joint cylinders, having two features, one is to ensure that cylinder junction seals reliable, durable (should ensure that after general sealing and no longer dismantle cylinder in 1 year because of leakage problem);Two is seal position also to must endure as high pressure (>=100MPa).
Two way seal ring material its hardness after modifier treatment should be less than the hardness of cylinder, and such cylinder is when being in sealing state, and what plastic deformation occurred for it is only two-way sealing ring, and cylinder is that plastic deformation will not occur when sealing state.

Detailed description of the invention
A kind of sealing structure connected for supertension cylinder, as shown in Fig. 1,2,3,4,5, this sealing structure connects two cylinders, this sealing structure includes two-way sealing ring, clip and studs, described two-way sealing ring is placed between two joint cylinders, adopting clip to save cylinder by two to strain and fixed by studs, the described conical surface of two joint body end surface compresses with the both sides conical surface of two-way sealing ring, to reach the effect sealed.
The endoporus of described barrel end is the conical surface of 9 ��, and cylinder internal diameter d3 scope is between 100mm-500mm. The two ends cylindrical of described two-way sealing ring is 8 �� of conical surfaces, and its internal diameter d1 scope is between 100mm-480mm.
The hardness of the material of described two-way sealing ring is not more than the hardness of described cylinder material.
Two-way sealing ring is placed between two joint cylinders, slowly mobile cylinder, make cylinder slowly near two-way sealing ring, after the two ends outer conical surface of the two endoporus conical surfaces and two-way sealing ring saving barrel end is fully contacted (noting: now two-way sealing ring not yet deforms), two lobe clips are placed in the big step N place of cylinder end end again, unthreaded hole 5 place traverse studs on clip both sides, screw on nut, two lobe clips are constantly tightened, the inclined-plane of clip endoporus 6 is in the inclined-plane slip slowly at the big step place of barrel end, thus saving cylinder tensions slowly by two. The endoporus conical surface of barrel end slowly extrudes the outer conical surface at two-way sealing ring two ends so that the conical surface generation plastic deformation of two-way sealing ring, to reach the effect sealed. Two-way sealing ring adopts 42CrMo or the identical modified material of alloy of other mechanical performance, cylinder and clip to adopt PCrNi3MoVA or high-temperature alloy material, and bolt adopts low-alloy quenched and tempered steel. Two way seal ring material its hardness after modifier treatment should be less than the hardness of cylinder, and such cylinder is when being in sealing state, and what plastic deformation occurred for it is only two-way sealing ring, and cylinder is that plastic deformation will not occur when sealing state.
