Detailed Description

The following will further describe a female connection structure of polyethylene pipe according to the present invention by way of example and with reference to the accompanying drawings.

Referring to fig. 1-4, the utility model provides a socket type connection structure of a polyethylene pipe, which comprises a connection sleeve 1, and is characterized by further comprising a socket 2 arranged on two sides of the connection sleeve 1 and used for socket type installation of the pipeline, and a limiting table 3, a sealing groove 4 and an anti-drop device 5 arranged on the socket 2, wherein the limiting table 3 is provided with an annular groove 31, the sealing groove 4 is provided with a sealing ring 6 matched with the sealing groove 4, the anti-drop device 5 comprises an annular ring 51 arranged on the socket 2 and a plurality of elastic pressing sheets 52 arranged on the annular ring 51, the elastic pressing sheets 52 are provided with a plurality of barbs 53, and the annular groove 31 is provided with a second sealing ring 32; the second sealing ring 32 is arranged on the limiting table 3, so that the end surface of the pipeline is prevented from being in hard contact with the limiting table 3, and the limiting table 3 and the end surface of the pipeline are sealed through the second sealing ring 32; through the arrangement of the sealing ring 6, the pipeline is inserted into the bell and spigot 2, the sealing ring 6 is positioned between the outer wall of the pipeline and the bell and spigot 2, and the sealing ring 6 is continuously inserted and extruded with the pipeline, so that the sealing ring 6 is deformed and filled between the outer wall of the pipeline and the bell and spigot 2, and the sealing effect is achieved; through anticreep device's setting, in pipe insertion bell and spigot 2, pipeline end surface extrusion elasticity preforming 52, make elasticity preforming 52 receive extrusion deformation, it is tight with spacing platform 3 through second sealing washer 32 until the pipeline end surface, barb 53 on the elasticity preforming 52 penetrates in the outer wall of pipeline under elasticity preforming 52's bounce at this moment, thereby spacing fixed with the pipeline, mounting means through the socket joint formula, accomplish the piping erection fast, promote assembly efficiency, annular arrangement's elasticity preforming 52 has played the effect of support to the pipeline simultaneously, stability when having promoted the piping erection.

The sealing groove 4 comprises a groove 41 arranged on the bell and spigot 2 and a clamping groove 42 arranged in the middle of the groove 41, and a clamping block 43 for preventing the sealing ring from slipping is arranged on the side wall of the clamping groove 42; through the setting of seal groove 4, aim at recess 41 and draw-in groove 42 with sealing washer 6 and insert sealing washer 6 to recess 41 and draw-in groove 42 in, utilize fixture block 43 with sealing washer 6 spacing in draw-in groove 42 to promote the stability of 6 installations of sealing washer, prevent that the pipeline from relying on when passing sealing washer 6 to run through the nature and pulling out seal groove 4 with sealing washer 6, and then promote sealed effect.

In the utility model, firstly, a pipeline is aligned with a bell socket 2, the pipeline is inserted into the bell socket 2, the end surface of the pipeline firstly contacts an elastic pressing sheet 52, the outer wall of the pipeline extrudes the elastic pressing sheet 52 to deform along with the insertion of the pipeline, the pipeline penetrates through the elastic pressing sheet 52 and then continuously penetrates through a sealing ring 6 until the end surface of the pipeline is tightly attached to a limiting table 3 through a second sealing ring 32, at the moment, the sealing ring 6 is extruded and deformed between the outer wall of the pipeline and the inner wall of the bell socket 2 and is filled between the outer wall of the pipeline and the inner wall of the bell socket 2, so that the sealing effect is achieved, at the moment, barbs 53 on the elastic pressing sheet 52 penetrate into the outer wall of the pipeline under the effect of the elastic force of the elastic pressing sheet 52, so that the pipeline is limited and fixed in the bell socket 2, namely, the assembly between the pipeline and a connecting sleeve 1 is completed, the assembly between the two sides of the connecting sleeve 1 and the pipeline adopts a bell socket type installation mode, thereby avoiding the hot melt installation of devices such as a generator and the like, the efficiency of installation has been promoted.
