Embodiment 1

[0016] like figure 1 An embodiment of the ductile iron pipe anchoring interface of the present invention is shown. like figure 1 As shown, the ductile iron pipe anchoring interface of the present invention includes a socket 2, a socket 1 inserted in the socket 2 and an annular fixing ring 8 fixed on the outer surface, and the socket 2 and socket 1 are sleeved on the socket 1 to connect the socket 2 and the socket 1 together pressure flange 3. like figure 1 As shown, the inner surface of the socket 2 is provided with an annular sealing groove 11 embedded with a sealing ring 10, and an annular cylindrical protruding ring 4 is fixed on the outer surface. It should be noted here that the shape of the protruding ring 4 is optimal. Choose a cylindrical shape, and the cylindrical protrusion is more convenient for the casting process of the socket, but it is not limited to this shape, any shape that can prevent the axial pull-out force is acceptable, such as the shape of the hook h...

Embodiment 2

[0018] In order to increase the anti-off strength of the interface and achieve better anti-off effect. like figure 1 As shown, on the basis of the first embodiment, there is a stop ring 9 movably fitted on the socket 1 , and the stop ring 9 is located on the left side of the fixed ring 8 . like figure 1 As shown, the stop ring 9 is located in the tapered inner hole 5, that is to say, the stop ring 9 is located in the space formed by the tapered inner hole 5 and the fixed ring 8. This structure means that the diameter of the outer surface of the stop ring 9 is larger than that of the tapered The smallest diameter on the left side of the inner hole 5 is at the same time the inner surface diameter smaller than the outer surface diameter of the retaining ring 8 . In order to further increase the anti-strength of the interface, such as figure 1 As shown, the outer surface of the retaining ring 9 is set as the tapered surface 12 with the same slope angle as the tapered inner...

Abstract

The invention discloses an anchoring connector of a ductile cast iron pipe. The anchoring connector comprises an inserting hole, a receiving hole and a pressure flange, wherein an annular conical inner hole is formed in the inner surface of the pressure flange; an annular groove matched with a convex ring is formed in the right side of the conical inner hole; a fixing ring is positioned in the conical inner hole and the diameter of the fixing ring is greater than that of the left side of the conical inner hole. According to the anchoring connector, the annular groove and the conical inner hole are formed in the pressure flange, and the strength of the pressure flange is fully utilized for connecting the inserting hole with the receiving hole without assistance of other accessories; the anchoring connector is simple in structure and convenient to mount; meanwhile, the structure can bear relatively large pull-out force and is good in anti-separation capability.

Description

Technical field [0001] The present invention involves an anchoring interface of the ball and ink cast iron tube, which is especially suitable for the water pipeline composed of the ball and ink cast iron pipe. Background technique [0002] In the process of inserting flexible interface ball -casting iron pipes, there are often uneven foundations, sinking, turning, climbing, stopping, and changing paths.Uniform question.The installation of the ball -ink cast iron pipe interface now uses more complicated, time -consuming and labor -intensive, and the existing anti -deductive interface has less anti -off -depnting ability. Invention content [0003] The technical problem to be solved by the present invention is to provide an anchoring interface with a simple structure, easy installation and strong anti -proofing capacity, thereby solving the problem of complex installation and poor anti -off ability in the existing technology. [0004] In order to solve the above technical problems...
