The utility model relates to the pipe installation technology field.
Background technique
Ductile iron pipe interface pattern is the Placement that must select in pipeline designs.Ductile iron pipe interface pattern is the Placement that must select in pipeline designs.The mechanical type K type interface of selecting in construction, it is simple in structure, adopts differential bolt connection convenient disassembly, can guarantee good sealability.But its shortcoming is the performance that does not possess anti-pull-off, turns, climb, stop at pipeline or buttress need to be set up in the place of reducing.In the situation that the place of some special location or limited space does not allow to set up buttress, must adopt the restriction interface to resist the thrust produced by hydraulic pressure.
The model utility content
The interface anchor structure that technical problem to be solved in the utility model is to provide a kind of ductile iron pipe has axial force simple in structure, as can to resist the hydraulic pressure generation, avoids setting up buttress, greatly reduces the pipeline construction expense.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of ductile iron pipe sealing differential anchor structure, comprise spheroidal graphite cast iron tube faucet, ductile iron pipe socket, seal ring and T-shaped bolt pair, also comprise the sealing differential with boss, described ductile iron pipe socket outer wall coordinates with the sealing differential with boss, ductile iron pipe socket outer wall is provided with the corresponding radial location hole more than 3 with the boss of sealing differential with boss, be provided with fastening screw trip bolt in positioning hole, fastening screw trip bolt coordinates with nut.
Preferably, the boss of the described differential of the sealing with boss be provided with more than 3 with the positioning hole square crossing, with the corresponding tapped hole of ductile iron pipe socket parallel to an axis, the tapped hole place is provided with the thrust screw.
Preferably, the radial location hole on described ductile iron pipe socket outer wall is the taper pipe thread hole, and the screw thread of described fastening screw trip bolt and nut is taper pipe thread, and described fastening screw trip bolt is sunk screw.
Preferably, described seal ring is K type O-ring seal.
Preferably, the described differential of the sealing with boss is whole annulus foundry goods.
The beneficial effect that adopts technique scheme to produce is:
This kind of ductile iron pipe sealing differential anchor structure is connected to form anchor structure by the pair of the clamping bolt on the sealing differential with boss and the positioning hole on the ductile iron pipe socket, coordinate the thrust screw to reduce axial displacement, can when guaranteeing sealing effect, prevent from throwing off mutually between the adjacent interface of ductile iron pipe, avoid setting up buttress, greatly reduce the pipeline construction expense, there is very strong practicability.
The accompanying drawing explanation
Fig. 1 is partial front elevation view of the present utility model;
Fig. 2 is the part sectioned view of Fig. 1.
In figure: 1-ductile iron pipe socket, 2-spheroidal graphite cast iron tube faucet, 3-is with the sealing differential of boss, 4-seal ring, 5-T type bolt pair, 6-fastening screw trip bolt, 7-thrust screw, 8-nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of ductile iron pipe sealing differential anchor structure, comprise spheroidal graphite cast iron tube faucet 1, ductile iron pipe socket 2, seal ring 4 and T-shaped bolt pair 5, also comprise the sealing differential 3 with boss, described ductile iron pipe socket 2 outer walls coordinate with the sealing differential 3 with boss, ductile iron pipe socket 2 outer walls are provided with the corresponding radial location hole more than 3 with the boss of sealing differential 3 with boss, are provided with fastening screw trip bolt 6 in positioning hole.
Preferably, the boss of the described differential of the sealing with boss 3 be provided with more than 3 with the positioning hole square crossing, with the corresponding tapped hole of ductile iron pipe socket 2 parallel to an axiss, the tapped hole place is provided with thrust screw 7.
Preferably, radial location hole on described ductile iron pipe socket outer wall is the taper pipe thread hole, and the screw thread of described fastening screw trip bolt 6 and nut 8 is taper pipe thread, and described fastening screw trip bolt 6 is sunk screw, taper pipe thread connects can play seal action, and leak at the urgent solid screw of anti-sealing 6 places.
Preferably, described seal ring 4 is K type O-ring seal.
Preferably, the described differential of the sealing with boss 3 is whole annulus foundry goods.
Installation method: first the sealing differential 3 with boss is enclosed within on ductile iron pipe socket 2, with the radial location hole on the boss of the sealing differential 3 of boss, with the positioning hole of ductile iron pipe socket 2 outer walls, aim at, fastening screw peg 6 and nut 8 are installed evenly fastening, then on ductile iron pipe socket 2, seal ring 4 are installed.Insert in spheroidal graphite cast iron tube faucet 1 installing with the sealing differential 3 of boss and ductile iron pipe socket 2 ends of K type O-ring seal, aim at the sealing differential 3 of boss and install with the flange bolt hole of spheroidal graphite cast iron tube faucet 1
t type bolt pair 5, if treat pitch smaller with the sealing differential 3 of boss with the too large available Lengthened bolt traction of flange bolt hole pitch of spheroidal graphite cast iron tube faucet 1, then the dehorn standard
tthe type bolt is the fastening seal request that reaches evenly, finally with thrust screw 7, holds out against one by one.
Because being subject to inside water pressure to do the used time, the interface position of ductile iron pipe produces axial force, ductile iron pipe socket 2 can outwards produce pull-off from spheroidal graphite cast iron tube faucet 1, this axial force is delivered between T-shaped bolt pair 5 and spheroidal graphite cast iron tube faucet 1 by the positioning hole on ductile iron pipe socket 2 and with the interaction of 6 of the fastening screw trip bolts on the sealing differential 3 of boss, resist this axial force because of the active force that is fastenedly connected between T-shaped bolt pair 5 and K type spheroidal graphite cast iron tube faucet 1, make interface can bear certain line pressure and do not produce pull-off.
This kind of ductile iron pipe sealing differential anchor structure is connected to form anchor structure by the fastening screw trip bolt 6 on the sealing differential 3 with boss, nut 8 with the positioning hole on ductile iron pipe socket 2, coordinate thrust screw 7 to reduce axial displacement, when guaranteeing sealing effect, can prevent from throwing off mutually between the adjacent interface of ductile iron pipe, avoid setting up buttress, greatly reduce the pipeline construction expense, there is very strong practicability.
