During novel torch pipeline compensator assembling, by following program, undertaken:
The first step: several (a plurality of) steel balls A16 is placed to respectively in the countersunk head pothole of pipe B1 near 4-6 inner set storing steel ball A16, then the inner of pipe A8 (non-reducing end) inserted to the specified position of pipe B1 inner side, then the outside that is anchored to pipe A8 and pipe B1 is overlapped to the O type pressure ring A7 of ring-type and the bellows of O type pressure ring B13 6 respectively in two ends, and by welding manner, the O type pressure ring A7 (one end that comprises bellows 6) of ring-type is weldingly fixed on to pipe A8 near the outer shroud specified position (as shown in Figure 1-Figure 3) of outer sleeve end socket 15 one end, then O type pressure ring B13 (the other end that comprises bellows 6) is weldingly fixed on to the specified position (as shown in Figure 1-Figure 3) of pipe B1 inner end (right-hand member) outer shroud.
Second step: (be circle structure because of outer sleeve end socket 15 by round-meshed outer sleeve end socket 15, circular hole is the interior ring of outer sleeve end socket 15) hitch is to the specified position (reducing end is divided) of the outer end outer shroud of pipe A8, and by welding manner, outer sleeve end socket 15 is weldingly fixed on to the specified position (reducing end is divided) of pipe A8 outer shroud, then bellows shock absorbing sleeve 21 is buckled into the specified position (for example middle part of bellows 6) in bellows 6 outsides, then inner side, one end is comprised to the outer sleeve 14 of countersunk screw 3 and with steel ball A12, overlaps together the outside specified position that is anchored to the parts such as bellows 6 with seal framework 11, and by welding manner, one end of outer sleeve 14 and overcoat end socket 15 are welded and fixed, so-called with the promising interior ring fixed position (as shown in Figure 1-Figure 3) of this outer sleeve 14 that in advance seal framework 11 is fixed on by welding manner.
The 3rd step: by the Sealing of ring-type 4 hitch to the common chamber forming of seal framework 11 inner sides and pipe B1 outer shroud, and make Sealing 4 be tight against sealing seat 5, then by seal gland flange 2 and with steel ball C10 cover, be anchored to pipe B1 outer shroud, and make the L-type minor face casting die end of seal gland flange 2 be tight against Sealing 4, then by extended type nut 9 and countersunk screw 3, link closely, and 2 pairs of Sealings 4 of seal gland flange are fixed.
The 4th step: by pre-stretching positioning architecture 19 hitch of ring-type to the outer shroud specified position of pipe B1 near outer end, and by welding manner, pre-stretching framework 19 is weldingly fixed on to pipe B1 outer shroud, then several pre-stretching struts 20 are inserted respectively in several through holes that pre-stretching framework 19 end faces are provided with, several setscrew nut A18 are screwed to respectively to the specified position of pre-stretching strut 20 simultaneously, then respectively pre-stretching strut 20 microcephaly's threaded end are screwed in extended type nut 9, and then limit screw cap 17 is screwed to respectively to the specified position (referring to structural representation Fig. 1) of pre-stretching strut 19 external end heads,
The 5th step: adopt fully automatic hydraulic special device to carry out the pre-stretching to bellows 6, when bellows 6 is pre-stretched to appointment elongation, by setscrew nut 18 and limit screw cap 17, regulate the pre-stretching amount (referring to structural representation Fig. 2) of locking bellows 6.
In sum, advantage of the present invention is:
1, the advantage of having gathered (FlexbleJoint) and (sleeve expansion joint) is in one, and medium adapts to more extensive.
2, certain gap is left in the inner side of the outer shroud of pipe A8 and pipe B1, and the outer ring surface of pipe A8 is fine finishing, and the tight latch closure of steel ball A16 being arranged by pipe B1 inner side is at the outer shroud of pipe A8; The outer ring surface of pipe B1 is fine finishing, and the tight latch closure of steel ball C10 that the steel ball B12 being arranged by Sealing framework 11 inner sides, seal gland flange 2 inner sides arrange, at the outer shroud of pipe B1, has formed close contact rolling friction;
3, the guiding axle center of steel ball A16, steel ball B12 and steel ball C10 is controlled; Also eliminated the surface friction drag of the parts such as pipe A8 (comprising the parts such as outer sleeve) and pipe B1 when the relative displacement of work operation left and right simultaneously.
4, the adjustable pre-stretching device of self structure equipment, can meet compensator when pipeline is installed, and can meet when bellows 6 is carried out to pre-stretching and reach to greatest extent, and this has just thoroughly eliminated the stress of pipeline when operation.
5, bellows shock absorbing sleeve 21 has been eliminated the unstable phenomenon of bellows 6 when flexible; Played again the cushioning effect of bellows 6 in running simultaneously.
The novel torch pipeline compensator of this spline structure, can really guarantee the operation of torch pipeline long-term safety, as once occur that special operation condition causes bellows explosion, because there is the existence that arranges of Sealing 4, finally can also guarantee that ducted hazardous medium there will not be leakage, be real safe and reliable; In structural drawing, can find out:
