Abstract
A linking rod pipeline flange 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 plurality of equal passive bars (7) which inosculate with and are placed on the inner wall of a pipeline are hinged with fixing bars (4, 6) through a plurality of equal middle bar (8); the fixing bars (4) is fixed on the inner side of the alignment disc (1); an active bar (5) passes through the central holes of the fixing bars (4, 6) and the alignment disc (1). 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 linkage 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 linkage 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 linkage type piping flange is to mouthpart, comprise flange and pipeline, on flange intrinsic in the band center hole the centering dish, coincideing places several passive bars that are equal to of inner-walls of duct by several intermediate bar hinged securement bars that is equal to, and fixing rod is fixed on centering dish inboard, and the center hole of fixing rod and centering dish is all passed by driving lever.
Three spill hinged seats that can insert intermediate bar evenly distribute on the above-mentioned fixing rod; Passive bar is three, and two ends are for inserting the spill hinged seat of intermediate bar; Intermediate bar is six; The centering dish is side band boss and fixes with fixing rod; Driving lever can be with fixing rod and is threaded.
The beneficial effects of the utility model are: because this has adopted driving lever and passive bar structure to mouthpart, fixing rod, intermediate bar and the passive bar formation linkage mechanism that is hinged, the power that comes from driving lever passes to passive bar by fixing rod and intermediate bar, make the inwall of passive bar extrusion pipe, assurance has the characteristics time saving and energy saving, that quality is high to the concentricity of mouthpart, flange and pipeline, can guarantee construction reference, easy to use, the counterpart quality is good.
Description of drawings:

Fig. 2 is the left view of fixing rod 4 among Fig. 1.
1-centering dish among the figure, 2-flange, 3-pipeline, 4-fixing rod, 5-driving lever, 6-fixing rod, the passive bar of 7-, 8-intermediate bar, 9-hinged seat.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in fig. 1, a kind of linkage type piping flange is to mouthpart, comprise flange 2 and pipeline 3, on flange 2 intrinsic in the band center hole centering dish 1, centering dish 1 one sides are the boss shape, boss and a fixing rod 4 are fixing, and three spill hinged seats 9 that can insert intermediate bar 8 evenly distribute on the fixing rod 4; Driving lever 5 and a fixing rod 6 of passing centering dish 1 center hole and fixing rod 6 are fixing, driving lever 5 can be with fixing rod 6 and is threaded, also can be fixedly connected, can adopt air pressure and hydraulic pressure when employing is fixedly connected is power source, driving lever 5 is moved reciprocatingly, three passive bars 7 that are fit to pipeline 3 inwalls are articulated in fixing rod (4 by six intermediate bars 8,6), the two ends of passive bar 7 are for inserting the spill hinged seat 9 of intermediate bar 8, in order to guarantee the centering precision of centering dish 1, fixing rod (4,6), three passive bars 7 and six intermediate bars 8 are shape size equity, and fixing rod (4 is inserted at the two ends of intermediate bar 8,6) hinged in the hinged seat 9, constitute linkage mechanism.Therefore, centering dish 1 places in the flange 2 with driving lever 5 and linkage mechanism and constitutes mouthpart, finishes the counterpart process.
In actual the use, earlier centering dish 1 is fixed on the flange 2, connect again mouthpart, the flange 2 that will connect then and mouthpart inserted in the pipeline 3 to be installed, dynamic action is on driving lever 5, fixing rod 6 moves to the direction of centering dish 1 on driving lever 5, cause passive bar 7 to produce a extruding force to pipeline 3 inwalls, make the inwall tight connecting of mouthpart with pipeline 3, 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 driving lever 5 counterrotatings, fixing rod 6 is to moving away from centering dish 1 direction, and the extruding force that 7 pairs of pipelines of passive bar 3 produce disappears, and flange takes out in the pipeline 3 that installs mouthpart.
Use this flange can guarantee construction reference to mouthpart, easy to use flexible, the counterpart quality is good.
Claims (6)
1, a kind of linkage 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, coincideing places several passive bars (7) that are equal to of pipeline (3) inwall by several intermediate bar that is equal to (8) hinged securement bars (4,6), and fixing rod (4) is fixed on centering dish (1) inboard, and the center hole of fixing rod (4,6) and centering dish (1) is all passed by driving lever (5).
