Description
Technical field
The utility model is related to a kind of compensating joint, specifically a kind of double flange limiting compensating joints.
Background technology
Compensating joint is called compensator at present, is chiefly used in axial displacement compensation, since pipeline is affected by thermal expansion and contraction, causes
Pipe deforming mostly uses compensating joint, is docked, and prevents the tearing of pipeline hardness from causing to disconnect, double flange limiting compensating joints
It is the compensating joint that both ends are all made of that flange is docked, with easy for installation rapid, the more preferable convenient advantage of maintenance, but due to
The variation of expanding with heat and contract with cold of pipeline, not only axially displaced slight displacement also occurs in vertical direction for pipeline, and flange pair
It connects and sealing and connection is realized using flange pinch seal circle, but due to the vertical direction displacement of pipeline, flange is caused to bite sealing
Circle makes the double flange limiting compensating joints of seal ring displacement, seal failure, and tradition mostly use single Seal Design, since this is close
Seal is located at outside, and when telescopic pipes displacement can bring sandy soil into, wear sealing ring, seriously affect the service life of sealing ring.
Utility model content
The purpose of this utility model is to provide a kind of double flange limiting compensating joints.
To achieve the above object, the technical solution of the utility model includes butt tube and abutted flange, and abutted flange is pair
Take over left end extends to form outward, and telescoping tube is socketed on the right side of butt tube, stop flange disk is equipped on the outside of telescoping tube, limits method
Orchid side of facing left is equipped with and is socketed in supported flange disk on telescoping tube, and the supported flange compressing that side is equipped on socket telescoping tube of facing left is close
Seal, telescoping tube upside are equipped with the Limit screw through stop flange disk, supported flange disk, abutted flange, Limit screw right side
It is socketed with stop nut, fixing bolt is equipped on the downside of telescoping tube, fixing bolt runs through supported flange disk and abutted flange disk, limit
Screw rod is connected and fixed with fixing bolt by fixing nut and supported flange disk, and telescoping tube left end docks side with butt tube and is equipped with tooth
Shape sealing ring, telescoping tube are equipped with groove corresponding with tooth form sealing ring, connecting flange, telescoping tube are equipped on the outside of telescoping tube right end
Docking casing is equipped on the inside of right end, tooth form sealing ring medial lateral is equipped with V-type protrusion, for reducing tooth form sealing ring and butt tube
Inboard friction resistance simultaneously keeps sealing.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model：
1, it is designed using inside and outside double containment, sealing effect is more preferable, and service life is long.
2, it realizes limitation connecting flange displacement by docking casing, and Butt sealing circle is made to be in concentric position with telescoping tube
Set, be connected firmly, reliably, sealing it is tight.
Description of the drawings
The utility model is described further in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, butt tube, 2, abutted flange, 3, telescoping tube, 4, stop flange disk, 5, supported flange disk, 6, compressing it is close

Acting flange, 14, docking casing.
Specific implementation mode
As shown in Figure 1, the utility model includes butt tube 1 and abutted flange 2, abutted flange 2 is that 1 left end of butt tube is outside
Side extends to form, and 1 right side of butt tube is socketed with telescoping tube 3, and 3 outside of telescoping tube is equipped with stop flange disk 4, and stop flange disk 4 is left
Side is equipped with the supported flange disk 5 being socketed on telescoping tube 3, and 5 left side of supported flange disk is equipped with the compressing sealing on socket telescoping tube 3
Circle 6,3 upside of telescoping tube are equipped with the Limit screw 7 through stop flange disk 4, supported flange disk 5, abutted flange 2, Limit screw 7
Right side is socketed with stop nut 8, and 3 downside of telescoping tube is equipped with fixing bolt 9, and fixing bolt 9 runs through supported flange disk 5 and rendezvous method
Blue 2 disks, Limit screw 7 are connected and fixed with fixing bolt 9 by fixing nut 10 and supported flange disk 5,3 left end of telescoping tube with it is right
1 docking side of take over is equipped with tooth form sealing ring 11, and telescoping tube 3 is equipped with groove 12 corresponding with tooth form sealing ring 11, and telescoping tube 3 is right
End outside is equipped with connecting flange 13, and docking casing 14 is equipped on the inside of 3 right end of telescoping tube, and 11 medial lateral of tooth form sealing ring is equipped with V
Type protrusion, for reducing tooth form sealing ring 11 and 1 inboard friction resistance of butt tube and keeping sealing.
The operation principle of the utility model：Dual-seal is realized by tooth form sealing ring 11 and compressing sealing ring 6, is ensured close
Feng Xing, and V-type protrusion is equipped in 11 inner side and outer side of tooth form sealing ring, realize sealing reduce again simultaneously tooth form sealing ring 11 with it is right
The frictional resistance of take over 1 influences the movement of telescoping tube 3, while corresponding groove 12 being arranged on telescoping tube 3, prevents tooth form close
Seal 11 falls off in 3 moving process of telescoping tube, by docking casing 14, realizes second compensation, while preventing connecting flange 13
Staggeredly cause docking fail the problem of.
