Abstract
A slide block type pipeline flange mouth connector mainly solves the problem that the prior tools are fussy in construction and great in the difficulty to guarantee standards and quality, which is characterized in that: the alignment disc (1) with a central hole inside is fixed on a flange (2); a lead screw (6) passing through the central hole of the alignment disc (1) is fixed on a baffle (7) fixed in a built-in pipeline (3); a sliding sleeve (4) is in thread connection with the lead screw (6); a plurality of sliders (5) are fixed on the baffle (7), having the inner and outer surface inosculating on the sliding sleeve (4) and the pipe wall (3). The utility model has the characteristics of time saving, labor saving and high quality, can ensure construction standards, and is convenient to use and good in connecting quality.
Description
Technical field:
The utility model relates to a kind of piping erection instrument, and particularly a kind of slide block type piping flange is to mouthpart.
Background technique:
In piping erection engineering work progress, often various types of valves will be installed on process pipe, and the structural type of valve is the flange connection mostly, therefore, often run into the welding of pipe and flange.Be the straightness that guarantees that process pipe is installed, when welding, must make pipe centerline and flange facing keep vertical.At present, equal usage level chi of each pipeline construction enterprise or Angle Steel Ruler are checked the perpendicularity of pipe centerline and flange facing, the shortcoming that exists is: 1, owing to be subjected to the restriction of welding neckflange boss structure, angle square can not be close to pipeline, gapped between angle square and the tube wall, and along with the increase of flange nominal diameter, this gap can be increasing, with the naked eye check that the perpendicularity of pipe centerline and flange facing has become very difficult, can not realize even this moment.2, once can only check the perpendicularity of a direction, and can not check the perpendicularity of other direction simultaneously.Therefore, said method can not guarantee the concentricity of pipeline and flange.
The model utility content:
Existing instrument construction is loaded down with trivial details in order to overcome, standard, deficiency that the quality assurance difficulty is big, the utility model provides a kind of slide block type piping flange to mouthpart, this can guarantee the concentricity that pipeline and flange are installed to mouthpart, guarantees construction reference, quality, and is simple to operation.
The technological scheme that the utility model adopted is: this slide block type piping flange is to mouthpart, comprise flange and pipeline, on flange intrinsic in the band center hole the centering dish, the leading screw that passes the centering center hole is fixed on the interior baffle plate of built-in pipe, and sliding sleeve and leading screw are for being threaded, and the inside and outside surface of being fixed on the baffle plate of several slide blocks is fit to sliding sleeve and tube wall.
Above-mentioned slide block can be three.
The beneficial effects of the utility model are: because this has adopted slide block and shift sleeve structure to mouthpart, make leading screw push slide block when driving the sliding sleeve motion, slide block passes to tube wall with extruding force, guarantee the concentricity that tube wall and flange and slide block sliding sleeve are formed to mouthpart, have the characteristics time saving and energy saving, that quality is high, can guarantee construction reference, easy to use, the counterpart quality is good.
Description of drawings:
Fig. 1 is the utility model structure sectional view.
1-centering dish among the figure, 2-flange, 3-pipeline, 4-sliding sleeve, 5-slide block, 6-leading screw, 7-baffle plate.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in fig. 1, a kind of slide block type piping flange is to mouthpart, comprise flange 2 and pipeline 3, on flange 2 intrinsic in the band center hole centering dish 1, the leading screw 6 that passes centering dish 1 center hole is fixed on the baffle plate 7 in the built-in pipe 3, sliding sleeve 4 and leading screw 6 are for being threaded, leading screw 6 and baffle plate 7 are fixed with nut, and slide block 5 can be three, also can be a plurality of being fixed on the baffle plate 7, the internal surface of slide block 5 is fit to sliding sleeve 4, outer surface is fit to pipeline 3, and taper sliding sleeve 4 forms wedge-shaped structure with slide block 5, and the spinning in and out of leading screw 6 make sliding into of sliding sleeve 4 skid off, can increase the extruding force of 5 pairs of pipeline 3 inwalls of slide block, thereby guarantee the centering of concentricity.
In actual the use, earlier flange 2 is connected with centering dish 1, the baffle plate 7 that again leading screw 6 is passed sliding sleeve 4 and be connected with slide block 5, and constitute mouthpart after nut is fixing, the flange 2 that will connect then and mouthpart inserted in the pipeline 3 to be installed, on the turn leading screw 6, leading screw 6 drives sliding sleeve 4 and moves to the direction of centering dish 1, extruding slide block 5, cause slide block 5 produce one to pipeline 3 extruding force, the outer surface that makes slide block 5 is with pipeline 3 tight connectings, to mouthpart, flange keeps concentricity with pipeline 32 this moments, the counterpart work of flange 2 is finished, can carry out spot welding after finishing counterpart, treat that flange 2 spot welding are fixing after, with leading screw 6 reverse turns, sliding sleeve 4 is to moving away from centering dish 1 direction, and the extruding force that 5 pairs of pipelines of slide block 3 produce disappears, and flange takes out in the tube wall 3 that installs mouthpart.
Use this flange can guarantee construction reference to mouthpart, easy to use flexible, the counterpart quality is good.
Claims (2)
1, a kind of slide block type piping flange is to mouthpart, comprise flange (2) and pipeline (3), it is characterized in that: the centering dish (1) of band center hole in flange (2) is upward intrinsic, the leading screw (6) that passes centering dish (1) center hole is fixed on the interior baffle plate (7) of built-in pipe (3), and sliding sleeve (4) and leading screw (6) are for being threaded, and the inside and outside surface of being fixed on the baffle plate (7) of several slide blocks (5) is fit to sliding sleeve (4) and tube wall (3).
2, a kind of slide block type piping flange according to claim 1 is characterized in that mouthpart: slide block (5) can be three.
