Description of drawings
Fig. 1 is the sectional drawing of the disassembling device of the utility model pipeline connection device.
Embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is elaborated.In the present embodiment, the equipment for the treatment of dismounting on the pipeline is with the bright for instance concrete technological scheme of the present utility model of valve.
With reference to shown in Figure 1, be the structural representation of the disassembling device of the utility model pipeline connection device.As seen from Figure 1, the disassembling device of pipeline connection device of the present utility model mainly comprises first fixed base 1 and second fixed base 2, it is the both sides of valve 6 that first fixed base 1 and second fixed base 2 lay respectively at band dismounting equipment, and be fixedly connected on the pipeline, separate the device of outwarding winding that valve is connected with pipeline and be connected thereby have the function of outwarding winding by at least one between first fixed base 1 and second fixed base 2.
In this preferred embodiment, at least one device of outwarding winding comprises screw rod 3 and the nut 4 of outwarding winding that is suitable for outwarding winding and cooperating with described screw rod 3, one end of described screw rod 3 is fixedlyed connected away from an end of pipeline with described first fixed base 1, the other end passes the circular hole that is arranged at described second fixed base, 2 respective end, the described nut 4 of outwarding winding is sheathed on the described screw rod 3, and between described first fixed base 1 and second fixed base 2, the aperture of described circular hole is greater than the diameter of described screw rod 3, and less than the external diameter of the described nut 4 of outwarding winding.
Like this behind the bolt that is totally released between pipeline valve 6 flanges and the piping flange, manually or with instruments such as spanners evenly turn the nut 4 of outwarding winding outward, the nut 4 of outwarding winding promptly produces outside thrust to second fixed base, thereby make the enough slits of formation between valve 6 flanges and the piping flange, taking valve 6 away overhauls or changes, after Awaiting Overhaul late gate or new valve reset and install pad, unclamp the nut 4 of outwarding winding, the connecting bolt of tightening valve 6 flanges and piping flange again gets final product.
For obtaining better to back down separating effect, above-mentioned at least one device of outwarding winding, promptly the outward winding screw rod 3 that cooperates and the nut 4 of outwarding winding can comprise two groups, two screw rods of these two groups of devices of outwarding winding preferably are symmetricly set in the two end part of first fixed base 1, the such two groups of screw rods 3 and the nut 4 of outwarding winding are being outwarded winding when cooperating, the axially loaded of pipeline can be more even, being connected of more convenient separation valve and pipeline.Two screw rods and the mode of fixedlying connected of described first fixed base can adopt welding or fixing riveted way, but are not limited thereto.
Outwards turn the nut 4 of outwarding winding for reaching, thereby make valve 6 separate the purpose of taking out valve 6 with pipeline, first fixed base 1 and second fixed base 2 need be fixedly connected on respectively on valve 6 pipelines on two sides, the screw rod 3 and the nut 4 of outwarding winding are outwarded winding when cooperating like this, first fixed base 1 and second fixed base 2 can not produce displacement on pipeline, avoid producing the result who causes valve and pipeline to separate.Therefore, the mode that can take to weld is fixed on first fixed base 1 and second fixed base 2 on the pipeline, perhaps can on first fixed base 1 and second fixed base 2 holding device be set it removably is fixed on the pipeline.For example, one non-sealing ring portion or annular groove is set on first fixed base 1, by this non-sealing ring portion or annular groove, first fixed base 1 can be set on the pipeline, and the two end part of this non-sealing ring portion radially extend to form clamping part and undertaken fastening by the screw bolt and nut cooperation.Equally, second fixed base 2 also can be provided with a non-sealing ring portion, and second fixed base 2 is set on the pipeline by this non-sealing ring portion, and the two end part of this non-sealing ring portion radially extend to form clamping part and undertaken fastening by modes such as screw bolt and nut cooperations.
For ease of the maintenance and the maintenance of pipeline, generally all be provided with the axial displacement member that can extraction duct carries out axial displacement on the pipeline.But for being connected of easier separation valve 6 and pipeline, can also on the pipeline in first fixed base 1 or second fixed base, 2 outsides, the axial displacement member that an extraction duct is carried out axial displacement be set, this axial displacement member is preferably expansion joint 5, and the screw rod 3 and the nut 4 of outwarding winding are more convenient and laborsaving when outwarding winding operation like this.
Be further detailed below in conjunction with the working principle of concrete working procedure: at first be totally released the bolt between pipeline valve 6 flanges and the piping flange the disassembling device of the utility model pipeline connection device, manually or with instruments such as spanners evenly twist the nut 4 of outwarding winding outward again, till between valve flanges and the piping flange enough slits being arranged, taking valve away overhauls or changes, after Awaiting Overhaul late gate or new valve reset and install pad, unclamp the nut 4 of outwarding winding, the connecting bolt of tightening valve flanges and piping flange again gets final product.
From the description of above-mentioned embodiment, be appreciated that key point of the present utility model is that the connection device both sides for the treatment of dismounting on pipeline are provided with two fixed bases, and outward winding and the device of separation function by having between two fixed bases, such as the screw rod and the nut of outwarding winding, connect, thereby remove connection device on the pipeline easily.Quick dismounting device of the present utility model not only can be used for pipeline connection devices such as dismounting valve, also can be used to other equipment on the dismounting pipeline, as flowmeter, filter etc.In this preferred enforcement, this device of outwarding winding is to adopt the screw rod and the nut of outwarding winding to cooperate, and as the case may be, this device of outwarding winding also can adopt the cooperation of other members or member, and adopting screw rod and the nut of outwarding winding when cooperating, its concrete group number that adopts also can change.Be understandable that equally; two fixed bases also are not limited to welding or method of clamping provided by the utility model with the mode of fixedlying connected of pipeline; as long as can be fixed in the two on the pipeline and prevent that it from producing displacement; can realize the purpose of this utility model, thereby fall into protection domain of the present utility model.
From foregoing description as can be seen, the disassembling device of pipeline connection device of the present utility model can take out fast and easily with pipe laying on equipment, alleviate dismounting intensity effectively, prevent the damage of pad simultaneously.
Need to prove at last; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characteristics being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.
