Jack bolt assembly A of the present invention use and when operating, but note coming first and second flange components 10,12 of clamp flange assembly F with the nuts and bolt assembly (not shown) of some maintenance first and second flange components 10,12.Jack bolt assembly A of the present invention preferably is used for replacing two such nut bolt components, and two complete jack bolt assembly A one-tenth are installed together flange assembly for 180 °.This jack bolt assembly A both had been applicable to adpting flange member 10,12, was applicable to the flange component 10,12 that separately connects together when needs are dismantled again.In general, the very big power of this separately requirement, thereby when finishing this work, understand some difficulty.And use jack bolt assembly A of the present invention, this process not to simplify, and more effective, it is also less to finish the needed auxiliary tools of same work.Any amount of jack bolt assembly A can be used to replace common bolt and nut configuration, but preferably they are placed on the circumference of flange assembly F flange ring equably, for example, if use three such jack bolt assembly A, they are spaced apart 120 ° on flange assembly F; If with four, then they are spaced apart 90 ° on flange assembly, or the like.Do the ability of having strengthened jack bolt assembly A like this, make it apply one between 10,12 extensin periods about equally and the separating force of coordinating at the coupling flange component, this point will be discussed below in more detail.
Shown in Figure 1B, 2B and 3B, locating flange assembly A preferably and flange assembly F be installed together, like this, main thread part P is screwed on first flange component 10 through in the threaded opening 10j that suitably processes, propulsion members M is configured in respectively between inner radial flange ring surface 10d, the 12d of flange component 10,12, and a receiving portion 20 and a pair threaded portion 22 stretch into and pass the opening 12j that processes on second flange component 12.The one suitable solid member 24 of executing is screwed on pair threaded portion 22, because the clamp structure of paying on the threaded portion 22 24 has carried out suitable clamping, just makes first and second flange components 10,12 that suitable position has been arranged.Under a kind of like this situation about compressing, propulsion members M can be configured in the cavity of inner radial flange ring surface 10d and 10c, the 12c formation of inner annular surface by loose ground, therefore, tighten up clamp structure 24 flange component 10,12 is tightened up, carry out appropriate structure operation.As a result, each jack bolt assembly and flange assembly
All be in its should the position on.When needs separately first and second flange components 10,12 time, use them at any time.
Illustrate now.When needs separate flange component 10,12 with replacing member 14, should unclamp all common bolt and nut components.Then, the tool engagement end 26 that instrument 27 should be placed on bolt member J is meshed.By rotational positioning bolt component J suitably, propulsion members M is close to the radially mating surface R that adjoins mutually with the second end 16C of threaded portion 16, therefore forces propulsion members M to the right, as Figure 1-3.Be rotated further bolt member J with the instrument that is engaged in tool engagement end 26, make propulsion members M press close to the inner radial flange ring surface 12d of second flange component 12, thereby be adjacent to (seeing Fig. 2 and Fig. 3) with it fully.Be rotated further propulsion members M is moved right resembling shown in Fig. 1-3, thereby on second flange component 12, apply a separating force with respect to first flange component 10.Threaded portion 16 is rotated further with respect to threaded openings 10j, rely on the effect of 18 couples of propulsion members M of the radially field of conjugate action of bolt member J, on propulsion members M, continue to load, by propulsion members M to being used for from first flange component 10 separately of second member 12, to finish the separation of flange component 10,12 second flange component 12.Certainly, when adopting a plurality of bolt member A to back down flange assembly F, the power that requirement is backed down is roughly even.Like this, the part that is applied by all jack bolt assembly A is backed down power should be about equally, thus guarantee flange component 10,12 can be rightly, balancedly separate.
Just as shown in Figures 2 and 3, the diameter of receiving portion 20 and pair threaded portion 22 preferably is slightly less than the diameter of opening 12j, like this, and when without lock out operation, it can play an effect common, general bolt, and uses more easy in normal fastening operation.In addition, owing to there are differences between the diameter of the receiving portion T of propulsion members and opening 12j, in needs, just can use insulating component 32(Fig. 1).It should be noted that under the situation of using insulating component 32, the size of sleeve 32e is fixed like this: when flange connects, (see Figure 1B),, in sleeve 32e, do not have compressive load owing to act on the securing member 24 of packing ring 24 and the effect between the propulsion members M.If this condition has satisfied, so back down or the process of lock out operation in, when threaded opening 10j rotated in whole jack bolt assembly A does with respect to first flange component 10, sleeve 32e just can not be damaged.Like this, we will see, no matter are need compress or unclamp the time, and all working all instrument 27 of available same size is finished.So, jack bolt assembly A can comprise the drive member 26c of tool engagement end 26, thereby makes instrument 27 can not only drive drive member 26c, and can also rotate clamp structure 24(Fig. 4).
Therefore, we as can be seen, jack bolt assembly A of the present invention only uses the flange opening of screw thread (being opening 10j) seldom to admit the main thread part P of bolt member J in phase, just can be used on existing any flange.In most of the cases, jack bolt assembly A of the present invention need not just can retrofit on existing flange through break in service or stopping process.Therefore, jack bolt assembly A of the present invention provides double duty, and promptly it can be used for first and second flange components 10,12 of flange assembly F are tightened together, and can be used for again supporting, aim at and separates coupling flange component 10,12 together.In general, when when dismounting, no matter be axially or radially, the misalignment of flange component 10,12 is ordinary things.So just exist potential and dangerous misalignment power, these power can injure operating personnel.Yet jack bolt assembly A of the present invention can loosen and compress operation easily and safely, can not bring very big danger to operation because this misalignment power is arranged again.
In the case of necessary, an additional locking member that resembles the locking nut (Fig. 2 B) can be installed, it is screwed on the main thread section P, main thread part P extends outwardly into and exceeds first flange component 10, so that surperficial 10f fits with the outer radial flange ring of first flange component 10, thereby can under restraint location, strengthen lock bolt and the fastening force of bolt member J and flange component F.In addition, we it can also be seen that propulsion members M is in the position between the flange component 10,12, in case of necessity, and the lubrication channel that in separation process, can facilitate.If the part of the screw-threaded engagement between the main thread part P and first flange component 10 must be carried out extra lubricating.Can adopt one oil nozzle 38(Fig. 1 is housed) proper lubrication hole 36.To admit needed lubricant.
So, jack bolt assembly A of the present invention provides a kind of novel and device of having improved, it can not only be used for the flange component 10,12 of flange assembly F is tightened together, and the time can also be used for separating effectively in dismounting, the flange component 10,12 of aligning and pivot flange assembly F.
The front is that illustrative and indicative various variations at size, shape, material and the CONSTRUCTED SPECIFICATION introduced do not exceed spirit of the present invention about announcement of the present invention and description.
