The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The separated adjustment instrument of butterfly valve flange of the present invention, comprise main fixation kit and secondary fixation kit and drive screw mandrel, described main fixation kit and secondary fixation kit all have and the internal thread hole that drives screw mandrel to coordinate, described secondary fixation kit also has Level tune part and horizontal drive structure, and described horizontal drive structure can promote Level tune part and move along butterfly valve flange radial direction; Described main fixation kit and secondary fixation kit also all include for being fixed in the flange fixation kit on flange.
During use, need the separated adjustment instrument of two covers butterfly valve flange of the present invention to be used in conjunction with, main fixation kit is connected by driving screw mandrel with secondary fixation kit, as shown in Figure 3, on the different flanges that the main fixation kit of the separated adjustment instrument of every cover butterfly valve flange of the present invention and secondary fixation kit are arranged on respectively butterfly valve two ends, rotating drive screw mandrel, makes main fixation kit and secondary fixation kit constantly close, until main fixation kit 1 and secondary fixation kit 3 are adjacent to respectively the inner edge face of both sides flange 8.Take out flange bolt, adjust the relative position that drives screw mandrel 2 to change between main fixation kit 1, secondary fixation kit 3, make two flange faces in appropriate location, take out the butterfly valve of flange inside.Utilize subsequently flange fixation kit that main fixation kit and secondary fixation kit are fastenedly connected itself and flange.As shown in Figure 4, the separated adjustment instrument of the cover of two after installing butterfly valve flange of the present invention is preferably positioned on the same diameter of circular flange.
The function of described flange fixation kit is that main fixation kit or secondary fixation kit are firmly connected with fitted flange, the invention provides a kind of specific embodiment, by pressing plate 7 and the second hold-down bolt 6, formed, on described pressing plate, there is the screw coordinating with the second hold-down bolt 6.By the second hold-down bolt, through screw, pressing plate is close to flange, main fixation kit or secondary fixation kit are firmly connected with fitted flange.For further strengthening thrust, on described pressing plate, steady pin 9 can also be installed.
During parting flange, the driving screw mandrel that simultaneously rotates the separated adjustment instrument of two cover butterfly valve flanges, constantly increases main fixation kit and secondary fixation kit spacing, and rotary speed should be tried one's best unanimously, avoid flange to be bent, causing can not normal mounting after taking off or occur dehiscing while installing.Can use spanner to clamp and drive screw mandrel uniform rotation, for avoiding spanner to skid, the spanner clamping face of pair of parallel can be set at the middle part that drives screw mandrel, convenient wrench clamping, for example driving cross section, screw mandrel middle part is square or regular hexagon.
In the time need to eliminating dehiscing between flange, first determine the direction of dehiscing, for example on dehisce, adjust the driving screw mandrel of the separated adjustment instrument of butterfly valve flange of top, main fixation kit 1 and secondary fixation kit 3 are moved in opposite directions, the driving screw mandrel 2 of simultaneously adjusting the separated adjustment instrument of below butterfly valve flange oppositely moves main fixation kit 1 and secondary fixation kit 3, and stretching and compression by the separated adjustment instrument of two cover butterfly valve flanges to the right diverse location of flange, can correct and dehisce.
When two flange occurred level dislocation, main fixation kit is arranged on to the outstanding one side of flange face, by horizontal drive structure, promote Level tune part outstanding flange face is pressed down, reach the object of adjusting dislocation.
Described horizontal drive structure can be rotated the first hold-down bolt for the first hold-down bolt that is arranged on secondary fixation kit top and extends inward, and the first hold-down bolt end promotes described horizontal drive assembly and moves along butterfly valve flange radial direction.
Said method is applicable to the less situation of horizontal displacement, when the horizontal displacement of two flanges is larger, the present invention discloses a kind of separated adjustment instrument of butterfly valve flange that is applied to large horizontal displacement error correction, on aforementioned component basis, also comprise hinge, support bar and jockey, described jockey is used for connecting hinge and support bar, secondary fixation kit or main fixation kit.
Operating procedure is as follows: 1. hinge 10 is fixed on to dislocation high one end of flange.2. on main fixation kit 1, bracing frame 12 is installed.3. use jockey 11 that secondary fixation kit 3 is fixedly connected with bracing frame 12 with bracing frame 12, hinge 10.4. adjust the position of Level tune part 5, reach the function of adjusting parallel flange dislocation.
The function of jockey is for connecting all parts, a kind of optimal way is connecting rod, described connecting rod two ends are fixed with respectively hook, the shaft of described connecting rod can stretch at length direction, described main fixation kit and/or secondary fixation kit top are fixed with the first draw ring simultaneously, and described chain connection has the second draw ring.As shown in Figure 5, the hook at connecting rod two ends catches on respectively the draw ring on secondary fixation kit and hinge, by the moment of bracing frame, transmits, and regulates the relative position of dislocation flange.
At pipeline, gather, the region of narrow space, the present invention preferably uses the support bar that is isosceles triangle, and described main fixation kit top also has with the groove of isosceles triangle drift angle form fit and 1. hinge 10 is fixed on to one end that dislocation flange is relatively high.2. support bar 12 is packed from left to right into the top of secondary fixation kit 3, use jockey 11 by the corner position of support bar and main fixation kit 1 top groove.3. adjust the position of Level tune part 5, reach the function of adjusting parallel flange dislocation.
Maximum technical characterictic of the present invention is to utilize positive and negative bolt to transport in opposite directions merit principle for basic point, can reflect really the amount of exercise between two flanges.Utilize that in same instrument, can to carry out butterfly valve flange separated, solve horizontal displacement, the problem such as dehisce up and down.
Adopt the separated adjustment instrument of butterfly valve flange of the present invention, in butterfly valve maintenance, realize valve flanges separated fast, simultaneously can the original duty of actual response flange face, complete the adjustment of any butterfly valve two flange spaces, the present invention also can be used for the problem that accurate adjustment butterfly valve flange position or spacing solve the dehiscing up and down of flange, parallel misalignment, make the decrement measured value of flange gasket more true and reliable, make flange face sealing in butterfly valve maintenance process reach onsite acceptance standard.
The present invention manufactures simply, with low cost, and light and handy, simple to operate, applicable small space, is convenient for carrying; Applicable all horizontal and vertical ring flanges; Can meet nuclear power station butterfly valve bolt and change the tight power of needs.
Previously described is each preferred embodiment of the present invention, preferred embodiment in each preferred embodiment is if not obviously contradictory or take a certain preferred embodiment as prerequisite, each preferred embodiment arbitrarily stack combinations is used, design parameter in described embodiment and embodiment is only the invention proof procedure for clear statement inventor, not in order to limit scope of patent protection of the present invention, scope of patent protection of the present invention is still as the criterion with its claims, the equivalent structure that every utilization description of the present invention and accompanying drawing content are done changes, in like manner all should be included in protection scope of the present invention.
