Description
Technical field
The utility model belongs to pipeline engineering, mechanical engineering, chemical field etc., specifically a kind of flange welding centering folder
Tool.
Background technique
Tar production factory boiling plant crude naphthalene naphtalene oil groove top portion's naphtalene oil pipeline because throughout the year corrosion caused by pipe leakage,
Great hidden danger is brought to safety in production, in order to guarantee to keep the safety in production, needs to replace naphtalene oil pipeline.Normal construction is pipe
Road is prefabricated, and in groove top portion, one group of flange is first connected with by flange, the flange and pipe that then will not welded with electric welding
It is welded in road.And according to corporate policy, naphtalene oil groove top portion forbids fire operation.Its difficulty of construction is that prefabricated pipeline exists
When trough top and flange abutting joint in the case where not getting angry, how to fix just and can guarantee that flange and flange can be entirely on the center.
Summary of the invention
The utility model provides flange welding centering clamp, solves the nozzle centering in flange and pipeline welding process
Problem.Its structure is simple, and processing cost is low, is very suitable to engineer application.
The technical solution adopted in the utility model is: a kind of flange welding centering clamp, by flange fixture block, connection bolt and
Screw three parts composition is adjusted, wherein flange fixture block there are two pieces, and inside design has stair-stepping V-shaped groove, is used for clamping flange
Outer annular face；Two pieces of flange fixture blocks are bolted by two groups of connections, force flange fixture block to utilize by tightening connection bolt
The stair-stepping V-shaped groove clamping flange lateral surface of inside, cascaded surface and flange upper surface cooperate, and position to flange fixture block solid
It is fixed；It adjusts screw to cooperate by screw thread pair and the threaded hole on flange fixture block top, passes through four adjustings on regulating flange fixture block
The position of screw makes the nozzle of pipeline be located in flange center, the centering of nozzle and flange before completing welding.
It is opposite with flange center mouthful to adjust pipeline nozzle by adjusting the position for adjusting screw using the utility model
Position, realizes the centering of nozzle and flange center mouthful, and is fixed the fixture of the utility model with flange by flange fixture block
Together, position will not shift, so that nozzle will not shift after adjustment is in relative to the position of flange, this
After sample pipeline and flange welding position are confirmed and fix in erecting bed, then pipeline and flange, which are moved to, allows open fire to exist
Construction area complete welding, prevent safety accident.

Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Illustrate implementation method of the invention by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
Refering to attached drawing, this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification
Revealed content is not intended to limit the invention enforceable restriction item so that those skilled in the art understands and reads
Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing
Under the effect of present invention can be generated and the purpose that can reach, it should all still fall in disclosed technology contents and obtain and can contain
In the range of lid.Meanwhile cited position restriction term in this specification, it is merely convenient to being illustrated for narration, rather than to
It limits the scope of the invention, relativeness is altered or modified, under the content of no substantial changes in technology, when being also considered as
The enforceable scope of the present invention.
Flange welding centering clamp structure provided by the utility model is as shown in Fig. 1, now in conjunction with Fig. 2 and Fig. 3 do into
One step is described in detail:
A kind of flange welding centering clamp is made of flange fixture block 2, connection bolt 3 and adjusting 1 three parts of screw, wherein
Flange fixture block 2 has two pieces, and inside design has stair-stepping V-shaped groove, is used for clamping flange outer annular face；Two pieces of flange fixture blocks
2 are connected by two groups of connection bolts 3, the stair-stepping V-shaped groove for forcing flange fixture block 2 to utilize inside by tightening connection bolt 3
Clamping flange lateral surface, cascaded surface and flange upper surface cooperate, and flange fixture block 2 is fixed on the positioning；Screw 1 is adjusted to pass through
Screw thread pair and the threaded hole on 2 top of flange fixture block cooperate, and are made by the position of four adjusting screws 1 on regulating flange fixture block 2
The nozzle of pipeline is located in flange center, the centering of nozzle and flange before completing welding.
The working principle of invention；
Firstly, connection bolt 3 is unclamped, until accommodate the space in two flange fixture blocks, the 2 stair-stepping V-shaped groove in inside can
The circular end face of flange；By in the V-shaped groove of scalariform perpendicular to V-shaped groove plane be close to flange will welded pipe line a side
Two groups of connection bolts 3 are tightened in face, are positioned fixture integrally and are fixed on flange.
Then, four on flange fixture block 2 are adjusted into screw 1 and back-outs the inner end portion until four adjusting screws 1 outward
Space can accommodate pipeline, pipeline nozzle is goed deep between four adjusting screws 1, tightening four adjusting screws 1 fixes nozzle.
Finally, being located in the nozzle of pipeline in flange by constantly regulate four on flange fixture block 2 adjusting screws 1
The heart, the centering of nozzle and flange before completing welding.Implement weldering after fixture, flange and pipe are moved integrally to welding procedure point
It connects, disassembles flange clamp after being welded and fixed, be detached from flange and implement the operation of centering next time.
