Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The structure of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the embodiment of the utility model provides a pair of interim quick connecting device of pipeline for hydraulic engineering, including first water pipe 1, the fixed second water pipe 2 that is provided with in right side of first water pipe 1, first sleeve 3 has been cup jointed in the outside of first water pipe 1, second sleeve 4 has been cup jointed in the outside of second water pipe 2, external screw thread 5 has been seted up to first sleeve 3's right side edge, the internal thread 6 of matcing external screw thread 5 has been seted up to second sleeve 4's left end edge inboard, connecting thread 7 has all been seted up in the medial extremity outside of first water pipe 1 and second water pipe 2, the equal threaded connection in the outside of two connecting thread 7 has limit nut 8, sealing washer 9 has all been cup jointed in the position that the first water pipe 1 and the 2 outside of second water pipe are close to limit nut 8.

Referring to fig. 1 and 2, the bottoms of the first sleeve 3 and the second sleeve 4 are both perforated with through holes 10 matching the outer diameters of the first water pipe 1 and the second water pipe 2.

Adopt above-mentioned scheme: through setting up through-hole 10, the external diameter of first water pipe 1 and second water pipe 2 is matchd to through-hole 10 size, can be so that first sleeve 3 and second sleeve 4 cup joint in first water pipe 1 and second water pipe 2 respectively.
