Abstract
The utility model relates to a fixed connecting structure for connectors of ductile iron pipes for water pipelines, which is especially suitable for water pipelines. An insertion connector of a ductile iron pipe is inserted into a socket of another ductile iron pipe, a sealing groove is arranged on the inner wall of the socket, a sealing ring is embedded into the sealing groove, a locking groove is arranged on the inner wall of the socket and at the left end of the sealing groove, a welded ring is fixed onto the insertion connector on the right side of the locking groove, a support ring is mounted in the locking groove on the left side of the welded ring, and a support ring inlet slightly larger than the support ring in size is arranged on the side wall of the left end of the socket to facilitate mounting and dismounting of the support ring. The fixed connecting structure is capable of preventing mutual separation between ductile iron pipes in a high-pressure water pipeline, and buttresses are omitted.
Description
Technical field
The interface that the utility model relates to a kind of ductile iron pipe connects firmly structure, is particularly suitable for aqueduct and uses.
Background technique
The most normal formula that the slips into T type interface of selecting for use in the construction, it is simple in structure, and is easy for installation, can guarantee excellent sealing performance.But its shortcoming is the performance that does not possess anti-pull-off, turns, climbs, stops at pipeline or buttress need be set up in the place of reducing.In some special location or limited place, space do not allow to establish under the situation of buttress, must adopt the restriction interface to resist the thrust that produces by hydraulic pressure.She Ji anti-slip interface can only satisfy the requirement of small dimension low-pressure line pressure in the past, and along with the raising of line pressure and the increase of specification, common self-anchoring joint can not meet the demands.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of aqueduct to connect firmly structure with the interface of ductile iron pipe, and it can prevent in high-pressure water pipeline that ductile iron pipe from throwing off mutually, avoids setting up buttress.
The technical scheme in the invention for solving the technical problem is: the socket of ductile iron pipe is inserted in the bellmouth of ductile iron pipe, on the inwall of bellmouth seal groove is arranged, be embedded with seal ring in the seal groove, on the bellmouth inwall of seal groove left end locking slot is arranged, weld-ring and bracing ring are housed in the locking slot, have the bracing ring import big slightly on the left end sidewall of described bellmouth, so that the loading and unloading bracing ring with the bracing ring size.
The utility model is simple in structure, can resist the axial force that hydraulic pressure produces, and avoids setting up buttress, reduces the pipeline construction expense greatly.Because there is cushion pad 2 in the left side of bracing ring, compressive strain when producing certain deflection, interface takes place, can satisfy the demand of flexible interface to angle of yaw.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model partial front elevation view;
Fig. 2 is the utility model partial left side view;
Fig. 3 is A-A partial sectional view second embodiment among the utility model Fig. 1.
Embodiment
As shown in Figure 1, 2, the socket 9 of ductile iron pipe is inserted in the bellmouth 6 of ductile iron pipe, seal groove 8 is arranged on the inwall of bellmouth 6, be embedded with seal ring 7 in the seal groove 8, on the bellmouth inwall of seal groove 8 left ends locking slot 4 is arranged, be fixed with weld-ring 5 on the socket 9 on locking slot 4 right sides, in the locking slot 4 in weld-ring 5 left sides bracing ring 3 is housed, have the bracing ring import 10 big slightly on the left end sidewall of described bellmouth 6, so that loading and unloading bracing ring 3 with bracing ring 3 sizes.
Described bracing ring 3 be shaped as arcuation, form by polylith, as shown in Figure 3.
Claims (3)
