Description
Technical field
The utility model relates to main equipment mounting technique field, more particularly, relates to the auxiliary device of a kind of fixing large-scale pipeline and valve adpting flange.
Background technique
In Saudi Arabia area, the material that underground fire protection pipeline uses mostly is RTR (glass fibre reinforced plastics), valve flanges on fire_fighting pipe network is also RTR material, in the structure of underground fire line, socket joint is mostly selected to connect between the fire protection pipeline of below caliber 500mm, the connection of valve flanges and pipeline also adopts socket joint to connect, the method that mounted valve was comparatively general on the pipeline of fixed position in the past is first connected with pipeline by the flange of valve side, then the opposite side flange of valve is installed on valve, finally again valve opposite side flange is connected with pipeline spigot-and-socket, said method is applicable to the pipeline of the metal material fixed or the non-metallic material pipeline of flat mouth connection, but be not suitable for the RTR pipeline that socket joint connects, first the RTR pipeline that socket joint connects is mounted valve flange, after pipeline pressure test is qualified, mounted valve again.
In Saudi Arabia's project, the construction sequence of plant area's underground fire protection pipeline should be: after RTR pipeline is installed according to the pressure testing bag divided, carry out the pressure testing of pressure testing bag, mounted valve again after the pressure testing of each pressure testing bag is qualified, then overall pressure testing is carried out, can backfill after overall pressure testing is qualified, but in the work progress of reality, often there is the delayed problem of valve arrival, cannot mounted valve in time after fire line terminates according to the pressure testing bag pressure testing divided, in order to not affect other professional constructions, for more construction space is created in job site, unit in charge of construction often first backfills the qualified pipeline of pressure testing, valve location be temporarily available do not backfill or valve flanges do protective measure after backfill, by the time valve installation is carried out again after valve arrival, so just there will be the situation that improper or two valve flanges of spacing between valve and mounted two valve flanges misplace, finally cause valve installation unsuccessful, valve installation is unsuccessful mainly contains several situation: a, between flange, spacing is excessive, between b, flange, spacing is too small, bell mouth shape is formed between c, flange, the bolt hole of d, two flanges is asymmetric.If mounted valve by force in the inappropriate situation of flange spacing, there will be the quality problems such as RTR pipe welding port cracking, RTR piping failure, valve flanges damage when tightening flange bolt, not only construction speed can be affected, increase construction cost, affect unit in charge of construction's fame, also can bring potential safety hazard to construction, the spacing backfilled between RTR pipeline valve flange of how controlling well is very crucial.
By patent retrieval, in prior art, existing related art scheme is open.As, application number 201420645260.X, the applying date is on October 31st, 2014, model utility name is called: a kind of large-scale pipeline and valve adpting flange installation auxiliary device, this application case comprises full flight screw, symmetry is arranged on 2 groups of full flight screw both sides and loosens and compensate cover and locking element, described full flight screw is set in flange hole corresponding to companion flange, its side being positioned at companion flange is by loosening the end face and flange hole close contact that compensate cover, its side be positioned at outside companion flange is locked by locking element, the described compensation cover that loosens is conical surface with flange hole surface of contact, loosen compensation to put and establish locating slot, described locking element is nut and pad, although this application case can play the effect of fixing tube flange spacing, but the stability of assistant apparatus structure needs to strengthen, device dismounting is inconvenient, and foreign material easily enter the blocking that pipeline causes pipeline.
