Example Embodiment

[0043] Example 1

[0044] An FRD double-sealed instant detection closed-water socket joint. The socket joint in this embodiment is used for the connection of polyolefin plastic drainage pipes, and includes a socket 1 and a socket 2. The socket 1 refers to the socket joint used Regarding the inserted part, the socket 2 refers to the part of the socket for socketing. An annular pressure test groove 4 is provided on the outer wall of the socket 1, and an annular seal ring installation groove is provided on both sides of the pressure test groove 4. In order to set a deeper pressure test groove 4 and a sealing ring installation groove, the outer wall of the socket 1 is provided with four annular partitions 11 in parallel, and the pressure test groove 4 and the sealing ring installation groove are both separated by the outer wall of the socket 1 and four annular partitions. Board 11 is enclosed. Due to the large number of drainage pipe specifications, the commonly used specifications...

Example Embodiment

[0050] Example 2

[0051] On the basis of embodiment 1, in order to facilitate installation, a plane support plate 6 is provided on one side of the socket 2, and the structure of the plane support plate 6 is as Figure 8 As shown, Figure 8 The viewing angle is slightly inclined toward the bottom of the flat support plate 6. The top of the flat support plate 6 is provided with an arc surface that matches the outer wall of the socket 2, and the top of the flat support plate 6 is also provided with a notch 61 for connecting with the socket 2. The reinforcement 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 flat support plate 6 is arranged at the lower end of the socket for supporting the ground, so that the positioning of the socket is more solid. In addition, the pressure test hole 22 is provided at the upper end of the socket 2, which is convenient for pressure test or sealant injec...

Abstract

The invention belongs to the technical field of closed water connection, and particularly relates to an FRD double-sealed immediate detection closed water socket-and-spigot joint. The problems that inthe prior art, a spigot and a socket possibly make contact with each other and are sealed, the positions which make contact with each other and are sealed are prone to causing connectivity of the interior of a annular space to be interrupted, accordingly, sealing performance detection of a double-sealed socket-and-spigot joint is uncompleted are solved. According to the technical scheme, the FRDdouble-sealed immediate detection closed water socket-and-spigot joint comprises a spigot and a socket, the spigot is a joint part of an inserting-in end, and the socket is a joint part of a socket end; the outer wall of the spigot is provided with an annular pressure test groove, the two sides of the pressure test groove are provided with annular sealing ring installation grooves correspondingly,and sealing rings are installed in the sealing ring installation grooves; and the socket is provided with pressure test holes which correspond to the pressure test grooves. In addition, baffles are arranged in the pressure test grooves. The FRD double-sealed immediate detection closed water socket-and-spigot joint is suitable for connection of drainage pipelines.

Description

technical field [0001] The invention belongs to the technical field of closed-water connection, and in particular relates to a FRD double-seal real-time detection closed-water socket joint. 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. Its 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 sealing rings on the sock...
