3. the utility model length is little, is convenient to the flexibility that can improve circuit design is installed.
4. the utility model inside needn't be provided with the water conservancy diversion sleeve pipe, can guarantee that medium flow field is stable, can avoid again because the water conservancy diversion sleeve pipe receives the medium power of disturbing to produce destruction.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 is casing flange, and 2 is grommet, and 3 is the flange cover, and 4 is flange, and 5 is compensate for clearance; 6 is first sleeve pipe, and 7 is second sleeve pipe, and 8 is the slip joint support, and 9 is stud bolt, and 10 is nut; 11 is double-screw bolt, and 12 is packing ring, and 13 is nut, and 14 is nut, and 15 is bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
As shown in Figure 1, the utility model comprises two sleeve pipes, promptly first sleeve pipe 6 and second sleeve pipe, 7, the first sleeve pipes 6 and second sleeve pipe 7 are formed a slip joint, is connected by push-and-pull rod, to press the influence of counter-force in eliminating; Be welded with casing flange 1 and flange 4 on first sleeve pipe 6 respectively; Second sleeve pipe 7 is identical with first sleeve pipe, 6 structures, be welded with casing flange 1 and flange 4 equally; Two casing flanges 1 and two flanges 4 are parallel to each other, and two flanges 4 are positioned at the outside, two casing flanges 1 are positioned at the inboard.Connect through a plurality of stud bolts 9 between two flanges 4 of first sleeve pipe 6 and second sleeve pipe 7, the two ends of each stud bolt 9 all are positioned at the outside of two flanges 4, on the two ends of the stud bolt 9 in two flange 4 outsides, are threaded with nut 10.Connect through a plurality of double-screw bolts 11 between two casing flanges 1 of first sleeve pipe 6 and second sleeve pipe 7; The two ends of each double-screw bolt 11 all are positioned at the outside of casing flange 1; On double-screw bolt 11 two ends in two casing flange 1 outsides, be threaded, and setting is enclosed within the packing ring 12 on the double-screw bolt 11 between the outer surface of nut 13 and casing flange 1 with nut 13.Each root double-screw bolt 11 and each root stud bolt 9 of the utility model are parallel to each other.
Leave between first sleeve pipe 6 and second sleeve pipe 7 can the suction line thermal expansion amount compensate for clearance 5, around the compensate for clearance 5, between two casing flanges 1, be provided with Sealing, with compensate for clearance 5 sealings.Sealing comprises grommet 2 and flange cover 3; Two casing flange 1 facing surfaces are provided with seam; All be with grommet 2 on the outer surface of first sleeve pipe 6 and second sleeve pipe 7, each grommet 2 all is positioned at the seam of casing flange 1, extruding and corresponding bushing outer surface butt through flange cover 3.Flange cover 3 is between two casing flanges 1, and the two ends of flange cover 3 are connected to two stop portions on the casing flange 1 respectively.The outer surface on grommet 2 tops is a cylinder, and the bottom of overlapping 3 butts with flange is divided into the conical surface, and flange cover 3 also is the conical surface with the face of grommet 2 butts.The material of the utility model Sealing can be confirmed according to the characteristic of medium in the pipeline, guarantees to connect between the sleeve pipe not have to leak.
