Embodiment 1

[0031] Embodiment 1: as figure 1 A socket-type pre-embedded pipe fitting shown includes: a socket-type pre-embedded connecting pipe body 1, a pipe body 2 coaxial with it is arranged on the inner side of the lower part, and a flange 3 is provided on the outer periphery of the top end of the pipe body 2. 3 is connected with the inner side of the socket-type embedded connecting pipe body 1 to form an integral structure, and the bottom end of the socket-type embedded connecting pipe body 1 and the bottom end of the pipe body 2 form a socket sealing cavity 4 . The outer periphery of the socket-type pre-embedded connecting pipe body 1 is provided with a water-stop ring 10 , which is located at the position corresponding to the flange 3 , and the outer periphery of the bottom end of the socket-type embedded connecting pipe body is provided with a waterproof boss 11 .

[0032] Such as figure 1 As shown, the connection between the flange 3 and the socket-type embedded pipe body, the c...

Embodiment 2

[0038] Embodiment 2: On the basis of implementing 1, such as Figure 4 and Figure 5 As shown, the socket-type pre-embedded connecting pipe body 1 is provided with an aligning sleeve 7, a sealing gasket 15 and an inner sealing ring 16, and the connecting flange at the top of the aligning sleeve 7 is uniformly provided with an aligning hole 71, and the socket Alignment grooves 12 are evenly arranged on the connecting flange at the top of the type pre-embedded connecting pipe body 1, and the alignment holes 7 and the corresponding alignment grooves 12 form a cross shape; a fastener 13 connects an alignment groove 12 and the alignment groove 12 The hole 7 is connected; the sealing washer 15 is arranged on the connection surface between the self-aligning sleeve 7 and the upper end surface of the socket type embedded pipe body 1, and the sealing is realized by locking the fastener 13 and pressing the sealing washer 15; inner sealing The ring 16 is arranged at the inner sealing surfa...

Embodiment 3

[0043] Embodiment 3: on the basis of embodiment 1, as Figure 6 As shown, the socket-type pre-embedded pipe fitting body 1 is provided with a side row interface 9, and the side row interface 9 is located above the socket sealing cavity 4; the side row interface is provided with a side row connecting cavity 91 and a side row sealing cavity 92. The side row connecting cavity is adjacent to the inner cavity of the socket-type pre-embedded connecting pipe body, and the side row sealing cavity is located outside the side row connecting cavity. A side sealing ring 8 is arranged at the side row interface 9 .

[0044] Such as Figure 9 As shown, the side sealing ring 8 includes a sealing cylinder 81, and the bottom of the sealing cylinder is provided with a port sealing surface 82 to seal the socket pipe body and the bottom end of the socket-type embedded pipe fitting body 1; the inside of the sealing cylinder There are up to one ring of deformed sealing strips 83 at intervals, and ...

Abstract

The invention provides a socket and spigot type embedded pipe fitting. The socket and spigot type embedded pipe fitting comprises a socket type embedded connecting pipe body, a pipe body coaxial withthe socket type embedded connecting pipe body is arranged on the inner side of the lower portion of the socket type embedded connecting pipe body, a flange is arranged on the periphery of the top endof the pipe body, the flange and the inner side of the socket type embedded connecting pipe body are connected into an integrated structure, and a socket and spigot sealing cavity is formed by the bottom end of the socket type embedded connecting pipe body and the bottom end of the pipe body. According to the socket and spigot type embedded pipe fitting, the problem that due to the design of the threaded connector of a socket and spigot type embedded pipe fitting, the installation of the socket and spigot type embedded pipe fitting and a socket connecting pipe is troublesome, and the use safety is poor is solved, therefore, the safety is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of water supply and drainage, in particular to a socket type pre-embedded pipe fitting. Background technique [0002] In the installation of the building drainage system, the embedded pipe fittings are set in the foundations such as walls and floors, and the upper and lower interfaces of the embedded pipe fittings are used to connect with the pipes. At present, the socket-type embedded pipe fittings are connected with the socket joints by flange glands and sealing gaskets, and the socket-type embedded pipe fittings are provided with threaded joints along the axial direction. The structure of this socket-type embedded pipe fittings and The structure of the matching socket connection pipe makes the installation of the socket type embedded pipe fitting and the socket connection pipe more cumbersome, and there are safety problems during use, and at the same time affects the service life; in addition, the socket type embed...
