Abstract
A kind of pipeline bus hinge type metal corrugated expension joint, it comprises shell flange, compensator body flange, bellows, hinge and securing member, it is characterized in that: bellows is clamped by shell flange and compensator body flange and fixed by securing member, hinge is arranged on the top of shell flange and compensator body flange, the utility model has the advantages that and jointly bear by the flange of bus housing and corrugated expansion joint body flange the blind flange force that hinge passes over, the greatly less thickness of corrugated expansion joint body flange, simultaneously, flange is utilized to dock bolt hole to install hinge, need not again on flange again perforate hinge is installed, reduce the external diameter of flange, reduce the space shared by whole machine installation.
Description
Technical field
The utility model relates to mechanical engineering technical field, particularly a kind of pipeline bus hinge type metal corrugated expension joint.
Background technology
Pipeline bus is used for that grid power transmission wire in power construction engineering is connected with the conductor between substation transformer, the wire jumper in transmission line and the connection in other power equipments, and hinge type metal corrugated expension joint is for compensating the lateral displacement of bus housing.Because pipeline bus is long, there is larger lateral displacement to need to compensate at " Z " type turning, for avoid due to expand with heat and contract with cold produce stress excessive cause housing ftracture gas leakage occur power outage, the hinge type compensator being generally used for compensation of pipeline needs thicker flange to bear because pipe interior inflates the blind flange force produced, and needs larger space to install hinge.
Summary of the invention
The utility model is just to provide a kind of equipment can reduce flange thickness, can reduce again the pipeline bus hinge type metal corrugated expension joint that installing space reduces the utilization of land resource.
The utility model realizes like this, it comprises shell flange, compensator body flange, bellows, hinge and securing member, it is characterized in that: bellows is clamped by shell flange and compensator body flange and fixed by securing member, and hinge is arranged on the top of shell flange and compensator body flange.
The utility model has the advantages that and jointly bear by the flange of bus housing and corrugated expansion joint body flange the blind flange force that hinge passes over, the greatly less thickness of corrugated expansion joint body flange, simultaneously, flange is utilized to dock bolt hole to install hinge, need not again on flange again perforate hinge is installed, reduce the external diameter of flange, reduce the space shared by whole machine installation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of pipeline bus hinge type metal corrugated expension joint.
Embodiment:
As shown in Figure 1, this pipeline bus hinge type metal corrugated expension joint comprises shell flange 1, compensator body flange 2, bellows 3, hinge 4 and securing member 5, bellows 3 is clamped by shell flange 1 and compensator body flange 2 and is fixed by securing member 5, and hinge 4 is arranged on the top of shell flange 1 and compensator body flange 2.Shell flange 1 pair of compensator body flange 2 plays booster action, while not increasing shell flange 1 thickness, substantially reduce the thickness of compensator body flange 2, dock bolt hole by shell flange 1, compensator body flange 2 simultaneously and hinge 4 is installed, substantially reduce the space shared by compensator body flange 2, bellows 3 compensation, sealing function.
