For achieving the above object, the technical solution of the utility model is: the tested table quick-connect machanism of a kind of flow meter, comprise adjustable pressure lap joint flange, the bolt scale with scale, bolt scale fixed block, be characterized in: on adjustable pressure lap joint flange end face, have uniform bar hole and four through holes, on adjustable pressure lap joint flange excircle, be fixedly connected with three uniform bolt scale fixed blocks, the bolt scale with scale is housed on bolt scale fixed block.
The head of the bolt scale with scale is equipped with steel ball.Adjustable pressure lap joint flange connects tested table flange by hexagon head bolt assembly.The external diameter of adjustable pressure lap joint flange and thickness are larger than PN100 standard board-like downhand welding steel pipe flanges external diameter and thickness under identical latus rectum respectively.Bar hole is composited by the circular hole of 22mm, 26 mm, 30 mm, tetra-kinds of specifications of 36 mm; Through hole is 22 mm through holes.
The beneficial effects of the utility model are:
1, the utility model mechanism adopts a kind of lap joint flange of new model, simple in structure, but the traditional lap joint flange of the function ratio that can realize is rich and varied.
2, have wide range of applications, can under various pressure, be suitable for, be widely used in the gentle flow calibrating device system of various water flow.
3, simple installation, working service cost is lower.
4. three bolt scales of quantitatively locating, only need simple adjustment scale to certain scale, just can realize fast automatic aligning, and have well solved this difficult problem.
Brief description of the drawings
Fig. 1 is structural upright schematic diagram of the present utility model;
Fig. 2 is structural front view of the present utility model;
Fig. 3 is adjustable pressure lap joint flange structural front view.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the tested table quick-connect machanism of flow meter of the present utility model, comprises adjustable pressure lap joint flange 1, the bolt scale 2 with scale, bolt scale fixed block 3, hexagon head bolt 4, steel ball 5, hexagon head bolt assembly 6, tested table flange 7.
On adjustable pressure lap joint flange 1 end face, have uniform bar hole 10 and four through holes 11, on adjustable pressure lap joint flange 1 excircle, be fixedly connected with three uniform bolt scale fixed blocks 3 by hexagon head bolt 4, the bolt scale 2 with scale is housed on bolt scale fixed block 3.
The head of the bolt scale 2 with scale is equipped with steel ball 5.Adjustable pressure lap joint flange 1 connects tested table flange 7 by hexagon head bolt assembly 6.
Adjustable pressure lap joint flange 1(is as Fig. 3), adjustable pressure specification is PN10, PN16, PN25, PN40, PN63, PN100; Bolt scale 2 with scale is the M20x120 bolt scale with scale; Steel ball 5 is S 14 steel balls; Hexagon head bolt 4 is M12x55 hexagon head bolt; Tested table flange 7, its pressure rating is PN10.
(1) in the tested table quick-connect machanism of flow meter, the external diameter of adjustable pressure lap joint flange 1 and thickness are all large than the board-like downhand welding steel pipe flanges of PN100 standard under identical latus rectum (Reference standard: GB/T 9119-2010), flange is mainly opened the through hole of two types, as shown in Figure 3: bar hole 10 is bar holes that the circular hole of 22 mm, 26 mm, 30 mm, tetra-kinds of specifications of 36 mm is composited, and through hole 11 is 22 mm holes.In the time that tested manometer pressure specification is PN10, the installation of tested table will complete by 22 mm parts and the through hole 11 of bar hole on flange 10, and bolt specification used is 8 of M20 quantity; In the time that the pressure specification of tested table is PN16, the installation of tested table will complete by 22 mm parts of bar hole on flange 10, and bolt specification used is 12 of M24 quantity; In the time that the pressure specification of tested table is PN25, the installation of tested table will complete by 26 mm parts of bar hole on flange 10, and bolt specification used is 12 of M24 quantity; In the time that the pressure specification of tested table is PN40, the installation of tested table will complete by the 30mm part of bar hole on flange 10, and bolt specification used is 12 of M27 quantity; In the time that the pressure specification of tested table is PN63 and PN100, the installation of tested table will complete by 36 mm parts of bar hole on flange 10, and bolt specification used is 12 of M33 quantity.Realize so completely without the rear straight pipe flange of table before changing table and just can carry out the installation demarcation of the tested table of many specifications.
