Abstract
The invention relates to a self-anchoring port fixedly-connecting structure of nodular cast iron pipes for a water pipe. A port of one nodular cast iron pipe is inserted into a bell mouth of the other nodular cast iron pipe, a sealing groove is arranged in the inner wall of the bell mouth, a sealing ring is embedded in the sealing groove, a press flange is supported against the left end face of the bell mouth, the press flange is fixed with the bell mouth through a bolt, a nut and a press block, the press flange is provided with a tapered inner hole, a port in the tapered inner hole is sleeved with a baffle ring, and a port at the right end of the baffle ring is fixed with a welding ring. Axial force generated by water pressure is resisted by using interaction among the port parts of the welding ring, the baffle ring, the press flange, the high-strength bolt and the press block, the nodular cast iron pipes can be prevented from mutually separating under a higher pipe operation pressure, setting of rest piers is avoided, thus the construction cost of the pipe is greatly lowered.
Description
Technical field
The present invention relates to a kind of aqueduct and connect firmly structure with the self-anchoring joint of ductile iron pipe.
Background technique
Ductile iron pipe interface pattern is the Placement that must select in the pipeline designs.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 PN10 low-pressure line pressure in the past, and along with the raising of line pressure, common self-anchoring joint can not meet the demands.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of self-anchoring joint and connect firmly structure, it can prevent that ductile iron pipe from throwing off mutually, has avoided setting up buttress, greatly reduces the pipeline construction expense.
The present invention solves the technological scheme that its technical problem takes: 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, there is differential on the top on the left side of bellmouth, differential is fixed by bolt, nut and briquetting and bellmouth, differential has cone-shaped inner hole, is set with baffle ring on the socket in the cone-shaped inner hole, fixing weld-ring on the socket of baffle ring right-hand member.
The present invention leans against on the bellmouth inclined platform by briquetting band sloping platform, with high-strength bolt briquetting and differential is connected to form from anchor.Because the increase of angle increases the bearing capacity of interface greatly in the raising of bolt strength and the differential.It can prevent that ductile iron pipe from throwing off mutually, has avoided setting up buttress, greatly reduces the pipeline construction expense.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a partial sectional view of the present invention.
Embodiment
As shown in drawings, the socket 11 of ductile iron pipe is inserted in the bellmouth 10 of ductile iron pipe, seal groove 9 is arranged on the inwall of bellmouth 10, be embedded with seal ring 8 in the seal groove 9, there is differential 3 on the top on the left side of bellmouth 10, and differential 3 is fixing with bellmouth 10 by bolt 1, nut 2 and briquetting 7, and differential 3 has cone-shaped inner hole 5, be set with baffle ring 4 on the socket 11 in the cone-shaped inner hole 5, fixing weld-ring 6 on the socket 11 of baffle ring 4 right-hand members.
Described differential 3 is whole annulus spare.
Interface is subjected to inside water pressure to make time spent generation axial force, the socket 11 of ductile iron pipe can be from bellmouth 10 outside pull-offs, this axial force is delivered on briquetting 3 and the bolt 1 by the interaction of 3 of the weld-ring on the socket 11 6, baffle ring 4 and differentials, because of bolt 1 has enough tensile strength, so the present invention can bear higher line pressure and not produce pull-off.
Claims (2)
1. a self-anchoring joint connects firmly structure, the socket of ductile iron pipe (11) is inserted in the bellmouth (10) of ductile iron pipe, seal groove (9) is arranged on the inwall of bellmouth (10), be embedded with seal ring (8) in the seal groove (9), it is characterized in that: there is differential (3) on the top on the left side of bellmouth (10), differential (3) is fixing by bolt (1), nut (2) and briquetting (7) and bellmouth (10), differential (3) has cone-shaped inner hole (5), be set with baffle ring (4) on the socket (11) in the cone-shaped inner hole (5), the socket (11) of baffle ring (4) right-hand member is gone up fixedly weld-ring (6).
2. self-anchoring joint according to claim 1 connects firmly structure, it is characterized in that: described differential (3) is whole annulus spare.
