3, with spanner, block the position of the stop draw-in groove 10 of little drive connector; With another spanner rotating nut 9, pipeline path joint 2, stuffing box packing 3 and movable sealing filler baffle plate 4 produce and axially move in opposite directions with self-locking block dunnage 7, make movable sealing filler baffle plate 4 promote self-locking block 5 actions;
4, will there is axial motion by movable sealing filler baffle plate 4 sides in self-locking block 5, by the end generation radial motion of the tube wall side in large-diameter pipe road 1, and be pressed on gradually on the tube wall in large-diameter pipe road 1 and will realize self-locking and fix;
5, continue rotating nut 9, the reaction force of movable sealing filler baffle plate 4 constantly increases, and makes stuffing box packing 3 that deformation occur, and produces radial expansion, realizes the seal action to pipeline internal medium.
The utility model, owing to having taked above technological scheme, has advantages of as follows:
1, without installment works such as mounting flange on metallic conduit, machining screw or welding;
2, without the fixedly work of reducer union of joints cement thrust pier on concrete duct;
3, can solve and in conventional pipelines reducing process, have the problems such as work consuming, consuming time and consumptive material;
4, this fast-assembling pipeline reducing diameter joint is applicable to the installment work of pipelines, is especially applicable to the pipeline that cast iron, cement etc. can not weld and cannot overlap the material making of tooth;
5, this fast-assembling pipeline reducing diameter joint is particularly outstanding for the connection advantage between the tapered pipeline of special-shaped hard material;
6, on the little drive connector of fast-assembling pipeline reducing diameter joint, plug being installed can be used as pipeline plug in addition, or setting pressure table, is applied to pipeline pressure test.
Accompanying drawing explanation:
Fig. 1 is the sectional drawing of fast-assembling pipeline reducing diameter joint;
Fig. 2 is the left view of fast-assembling pipeline reducing diameter joint;
The A figure of Fig. 3 is the sectional drawing of the self-locking block fixing spring mounting groove at self-locking block dunnage and edge thereof;
The B figure of Fig. 3 is the sectional drawing of pipeline path joint 2.
Embodiment
The utility model is comprised of pipeline path joint 2, stuffing box packing 3, movable sealing filler baffle plate 4, self-locking block 5, self-locking block fixing spring 6, self-locking block dunnage 7, packing ring 8, nut 9.
The other end of pipeline path joint 2 is processed with screw thread 12, with nut 9, coordinates, and by rotating nut 9, produces fixing seal filler baffle plate 11 on pipeline path joint 2 and the clamping force between movable sealing filler baffle plate 4.
Screw thread 12 on pipeline path joint 2 is processed into taper pipe thread by port section, so that the common tube joint of installation code, pipeline valve or other pipeline fittings.
The design quantity of self-locking block 5 changes according to pipeline diameter size and pipeline pressure: at pipeline diameter greatly, when pipeline pressure is large, increase self-locking block 5 quantity, otherwise minimizing;
Under normal pressure, install after pipeline reducing diameter joint, after boosting, pipeline needn't worry that joint is forced out large-diameter pipe road, because after pipeline pressure raises, stuffing box packing 3 and movable sealing filler baffle plate 4 will produce displacement, the pressure of 5 pairs of large-diameter pipe road walls of self-locking block increases auto lock tube wall.
Self-locking block dunnage 7 is designed to " gear " shape, be used for installing self-locking block 5, its working procedure is: when rotating nut 9, the distance of self-locking block dunnage 7 and movable sealing filler baffle plate 4 reduces and promotes self-locking block 5 with respect to large-diameter pipe road, to do axial motion by movable sealing filler baffle plate 4 sides gradually, according to the principle of lever, self-locking block 5 be take self-locking block dunnage 7 " tooth root " and with respect to self-locking block dunnage 7, is rotated as fulcrum, self-locking block 5 is done radial motion by large-diameter pipe road 1 side with respect to large-diameter pipe road 1 and is pressed on gradually on the inwall in large-diameter pipe road 1, to realize self-locking and fix, " tooth top " of self-locking block dunnage 7 is along the circumferential direction processed with half slot 13, for self-locking block fixing spring 6 is installed.
The effect of self-locking block fixing spring 6 is to prevent that the self-locking block 5 of fast-assembling pipeline reducing diameter joint from can not come off in transportation or handling process, and when in installation process, self-locking block 5 pushes self-locking block fixing spring 6, self-locking block fixing spring 6 can open again automatically.
The installation process of this packaged pipeline reducing diameter joint is as follows:
1, fast-assembling pipeline reducing diameter joint is placed in to the appropriate location in large-diameter pipe road 1;
2, with spanner, block the position of the stop draw-in groove 10 on pipeline path joint 2;
3, with spanner rotating nut 9, when nut 9 is locked to suitable degree, complete the installment work of reducer union.
In this fast-assembling pipeline reducing diameter jiont treatment process, the work interoperation of each constituent element is as follows:
1,, during initial rotating nut 9, under the effect of clamping force, pipeline path joint 2, stuffing box packing 3 and movable sealing filler baffle plate 4 produce and axially move in opposite directions with self-locking block dunnage 7, make movable sealing filler baffle plate 4 promote self-locking blocks 5 actions;
2, will there is axial motion by movable sealing filler baffle plate 4 sides in self-locking block 5, by the end generation radial motion of large-diameter pipe road 1 tube wall side, and be pressed on gradually on the tube wall in large-diameter pipe road 1 and will realize self-locking and fix;
3, continue rotating nut 9, clamping force constantly increases, and makes stuffing box packing 3 that deformation occur, and produces radial expansion, realizes the seal action to pipeline medium.
