Description

Special joint for pre-buried pipeline

Technical Field

The utility model relates to the technical field of embedded pipelines, in particular to a special joint for an embedded pipeline.

Background

The special connector is basically used in the construction process of the electromechanical embedded pipeline of the building at present, the length is about 50-60mm, the thickness is about 0.3-0.5mm, the pipe fitting is fixed by a set screw in the use process, and the connection is quick and convenient. However, the joint is a non-standard pipe, and the thickness of the joint is too thin, so that the joint is not fastened in place by workers in the actual operation process, the joint is stepped on in the reinforcement binding process, or the joint is frequently disconnected and blocked due to vibration of a distributor and a pump pipe in the concrete pouring process. After the existing concrete is poured, most of the pre-buried blocking pipes are blocked at the connecting parts, so that the concrete flows into the pipes, the blocking positions can be found by a detector in time, and the dredging can not be realized (the concrete slurry enters and is solidified into a whole). The blockage removal is realized by consuming a large amount of manpower and material resources, the effect is often not good, and the pre-buried pipeline is scrapped as a result.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the technical background, the utility model aims to provide a special joint for an embedded pipeline, which solves the problems that the embedded electromechanical pipeline joint provided in the background technology has low connection strength, the joint connection pipe is unstable and the concrete is easy to enter and block.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a buried pipeline special joint in advance, includes adapter sleeve, adapter sleeve inner middle part and bilateral symmetry are equipped with smooth district and internal thread respectively, smooth district to adapter sleeve both ends inboard is equipped with the tight gasket piece of clamp that the multiunit is used for pressing from both sides tight tube head, the longitudinal section who presss from both sides tight gasket piece is trapezoidal, the multiunit it is the setting of fill shape to press from both sides tight gasket piece, adapter sleeve both ends internally mounted has external screw thread pipe.

Furthermore, an arc-shaped chamfer is arranged on the inner side of the movable end of the clamping gasket block.

Furthermore, an annular inner groove is formed in an inner side port of the external thread pipe, and the external thread pipe and the internal threads at the two ends of the connecting sleeve are in installation relation.

Furthermore, the outer side end of the outer threaded pipe is fixedly connected with a rotary pipe head, and the inner diameter of the rotary pipe head is the same as that of the outer threaded pipe.

Compared with the prior art, the utility model has the following advantages:

(1) according to the utility model, the rotating pipe heads and the external threaded pipes are respectively arranged on 2 electromechanical casing pipe heads to be connected, then the electromechanical casing pipe heads are inserted into two ends of the connecting casing pipe, so that the clamping gasket blocks at two ends are positioned at the outer sides of the electromechanical casing pipe heads, the external threaded pipes are screwed into two ends of the connecting casing pipe by rotating the rotating pipe heads at two ends, the movable ends of the clamping gasket blocks are pressed into the inner sides of the external threaded pipes by the inner side grooves of the external threaded pipes, and the clamping gasket blocks are continuously screwed in to extrude and fix the electromechanical casing pipe heads by extruding the clamping gasket blocks.
