To achieve these goals, technical solution of the present utility model is such: pipe coupling comprises flanged joint, pipeline, the flange-type gland, seal ring, it is consistent with the outside end face curved surface of the pipe bulge loop that matches to compress end face in the flange-type gland, the inboard of flange-type gland is provided with interior belling ring, match with the inner side end of the interior belling ring of flange-type gland in the exterior edge face of seal ring, the inner cylindrical surface of seal ring matches with the external cylindrical surface of pipeline, the inner conical surface of seal ring matches with the male cone (strobilus masculinus) of flanged joint, wherein, the inner conical surface of seal ring, inner cylindrical surface, the exterior edge face constitutes a wedge-type seal circle together, inner conical surface, inner cylindrical surface, the exterior edge face is respectively the inclined-plane of wedge-type seal circle, face and be subjected to thrust face directly, correspondingly, the male cone (strobilus masculinus) of flanged joint, the external cylindrical surface of pipeline, the inner side end of interior belling ring has constituted a wedge-type seal seat, the male cone (strobilus masculinus) of flanged joint together, the external cylindrical surface of pipeline, the inner side end of interior belling ring is respectively the inclined-plane of wedge-type seal seat, face directly and thrust face.
Because in the above-mentioned technical solution, thereby adopt the flange connecting mode to replace the defective that scyewed joint has overcome prior art, have be connected firmly, advantage such as long service life,, convenient for maintaining little to water pollution, and the interior belling ring of flange-type gland directly provides sealing thrust to seal ring in connection process, and wedge-type seal circle and wedge-type seal seat cooperatively interact and can realize special reliable sealing performance in the above-mentioned pipe coupling.
Description of drawings
The structural representation of the flange-type pipe coupling that Fig. 1 provides for the utility model;
The structural representation of the seal ring that Fig. 2 provides for the utility model;
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Wherein: 1, flanged joint; 2, pipeline; 3, flange-type gland; 4, seal ring; 5, pipe bulge loop; 6, interior belling ring; 7, gland tail end protecting jacket; 4-1, exterior edge face; The 4-2 inner cylindrical surface; 4-3, inner conical surface; 4-4, transition external cylindrical surface.
Shown in Figure 2 as Fig. 1, the pipe coupling that the application provides comprises flanged joint 1, pipeline 2, flange-type gland 3, seal ring 4, it is consistent with the outside end face curved surface of the pipe bulge loop 5 that matches to compress end face in the flange-type gland 3, the inboard of flange-type gland 3 is provided with interior belling ring 6, the exterior edge face 4-1 of seal ring 4 matches with the inner side end of the interior belling ring 6 of flange-type gland 3, the inner cylindrical surface 4-2 of seal ring 4 matches with the external cylindrical surface of pipeline 2, the inner conical surface 4-3 of seal ring 4 matches with the male cone (strobilus masculinus) of flanged joint 1, wherein, the inner conical surface 4-3 of seal ring 4, inner cylindrical surface 4-2, exterior edge face 4-1 constitutes a wedge-type seal circle together, inner conical surface 4-3, inner cylindrical surface 4-2, the exterior edge face is respectively the inclined-plane of wedge-type seal circle, face and be subjected to thrust face directly, correspondingly, the male cone (strobilus masculinus) of flanged joint 1, the external cylindrical surface of pipeline 2, the inner side end of interior belling ring 6 has constituted a wedge-type seal seat, the male cone (strobilus masculinus) of flanged joint 1 together, the external cylindrical surface of pipeline 2, the inner side end of interior belling ring 6 is respectively the inclined-plane of wedge-type seal seat, face directly and thrust face.This pipe coupling structure is compact, flange connection wherein has preferably, and linking intensity also can provide enough big sealing thrust, again because the interior belling ring 6 of flange-type gland 3 directly provides sealing thrust to seal ring 4, thereby sealing effect is more satisfactory, and in the pipe coupling wedge-type seal circle be subjected to thrust face under the thrust face effect of wedge-type seal seat, thereby the inclined-plane of wedge-type seal circle and face directly and can and face crowded more being adjacent to more directly with the inclined-plane of wedge-type seal seat and reach a kind of desirable sealing effect, wherein also have characteristics to be no matter be being adjacent to of inclined-plane and inclined-plane seal or face directly and face directly to be adjacent to sealing or thrust face and to be subjected to the sealing that is adjacent to of thrust face all be uniform face seal rather than linear sealing, thereby sealing effect is more reliable.
When the external cylindrical surface of the interior belling ring 6 of flange-type gland 3 cooperates socket with the inner cylindrical surface of the corresponding position of flanged joint 1, the connection validity of whole pipe coupling can obviously improve the more accurate sealability that also can improve pipe coupling naturally of the cooperation meeting of associated components.
If the inner side end of the interior belling ring 6 of flange-type gland 3 and the inside edge of pipe bulge loop 5 are in same vertical surface, the inside edge of belling ring 6 and pipe bulge loop 5 produces the sealing thrusts to sealing 4 simultaneously in can making, and helps improving sealability.
The utility model is provided with the gland tail end protecting jacket 7 that is adjacent to pipeline 2 external cylindrical surfaces in the outside of flange-type gland 3, can make the pipe that is connected that better resistance to flexure is arranged near joint.
As shown in Figure 1 and Figure 2, between the inner conical surface 4-3 of wedge-type seal circle and exterior edge face 4-1, be provided with transition external cylindrical surface 4-4, be provided with the transition inner cylindrical surface between flanged joint 1 male cone (strobilus masculinus) of wedge-type seal seat and the inner side end of interior belling ring 6, owing to wherein be provided with the transition inner cylindrical surface on transition external cylindrical surface 4-4 and the corresponding flanged joint 1, thereby can make pipe coupling possess long sealing to compress distance, make that seal ring 4 might be pressed tightlyer, sealing effect is better.
In the utility model, definite benchmark of interior exterior orientation is: axially inwardly to serve as towards joint middle part direction, axially outwards be away from joint middle part direction at first; Secondly with towards pipeline or joint axial direction for radially inside, be radially outward away from pipeline or joint axial direction.
