Example Embodiment

[0045] Example 1

[0046] A polyolefin drainage pipe with FRD double-seal instant detection of closed water socket joints, including a pipe 5, the two ends of the pipe 5 are respectively provided with a socket 1 and a socket 2 in an integrated manner, and the socket 1 refers to The part used for insertion in the socket joint, the socket 2 refers to the part used for socket in the socket joint. That is, in the actual installation process, the socket 1 at one end of the drain pipe is inserted into the socket 2 at the other end of the drain pipe to form a pipeline. After the socket 1 and the socket 2 are matched and connected, the structure of the socket joint is as follows:

[0047] An annular pressure test groove 4 is provided on the outer wall of the socket 1, and an annular sealing ring installation groove is provided on both sides of the pressure test groove 4. In order to set the deep pressure test groove 4 and the sealing ring installation groove, the outer wall of the s...

Example Embodiment

[0053] Example 2

[0054] On the basis of Embodiment 1, in order to facilitate installation, one side of the socket 2 is provided with a plane support plate 6, and the structure of the plane support plate 6 is as follows Figure 8 as shown, Figure 8 The angle of view is slightly inclined toward the bottom of the plane support plate 6, the top of the plane support plate 6 is provided with an arc surface that matches the outer wall of the socket 2, and the top of the plane support plate 6 is also provided with a notch 61 for connecting with the socket 2. The reinforcing ring 21 on the outer wall cooperates. The bottom of the plane support plate 6 is provided with a plane. After the socket joint is installed, the plane support plate 6 is arranged at the lower end of the socket to support the ground, so that the positioning of the socket is more solid. In addition, the pressure test hole 22 is arranged on the upper end of the socket 2, which facilitates the operation of pressu...

Abstract

The invention belongs to the technical field of drainage pipes, and specifically relates to a polyolefin drainage pipe with FRD double seal for instant detection of a closed water bell and socket joint. The polyolefin drainage pipe aims at the problem that in the prior art, a socket and a bellmouth may be contacted and sealed, and the contacted and sealed parts may lead to the interruption of theinternal connectivity of an annulus, and then the incomplete detection of the sealing inspection of the double-sealed bell and socket joint may exist. According to the technical scheme, the polyolefindrainage pipe comprises a pipeline, two ends of the pipeline are separately provided with the socket and the bellmouth through an integral forming mode, an annular pressure test groove is arranged onthe outer wall of the socket, and annular sealing ring installation grooves are arranged on both sides of the pressure test groove; and a pressure test hole is formed in the bellmouth, the distance between the pressure test hole and a bellmouth opening is equal to the distance between the middle of the pressure test groove and a socket opening, and in addition, a baffle can be arranged in the pressure test groove. The polyolefin drainage pipe with the FRD double seal for instant detection of the closed water bell and socket joint is applicable to the connection of the drainage pipeline.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, and in particular relates to a polyolefin drainage pipe with FRD double-seal instant detection closed-water socket joints. Background technique [0002] The drainage pipe is connected and installed by the drainage pipes processed separately in multiple sections, and the connection structure between the water pipes is required to maintain a good sealing performance for a long time. In the prior art, the connection between water pipes often adopts socket joints. The connection method of socket joints is to insert the socket at one end of the pipe or fitting into the socket of the fitting to be connected, and fill the ring gap with sealing material. The advantage is that it is easy to install. [0003] There are many forms of sealing for socket joints, among which double sealing is a very effective sealing form. Moreover, by setting a pressure test hole at the position between the two seali...
