Description

Connecting pipe sealing structure for irrigation

Technical Field

The utility model relates to a pipe connection technical field specifically indicates a connecting pipe seal structure for irrigation.

Background

Irrigation refers to irrigation with water, and mainly comprises modes of flood irrigation, spray irrigation, micro-spray irrigation, drip irrigation, infiltrating irrigation, deficit irrigation and the like, and is divided into types of irrigation before sowing, seedling-accelerating irrigation, growth period irrigation, winter irrigation and the like. The irrigation principle is that the irrigation quantity, the irrigation times and the irrigation time are determined according to the water requirement characteristics, the growth stage, the climate and the soil conditions of the medicinal plants, and the medicinal plants are irrigated in a proper time and in a proper amount and reasonably. The irrigation needs to use pipelines, and the connection between the pipelines is very important.

The existing pipelines are connected by using the flange plates, the sealing performance of the branch connection mode is unstable, water still flows out from gaps, and a large amount of water resources are wasted in the past.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve foretell various problems, provide a simple structure, connect firm, sealed better for effect connecting pipe seal structure for irrigation.

In order to solve the technical problem, the utility model provides a technical scheme does: a sealing structure of a connecting pipe for irrigation comprises a first pipeline and a second pipeline communicated with the first pipeline, wherein a first flange is welded to one end of the first pipeline, a second flange is welded to one end of the second pipeline, the first flange and the second flange are fixedly connected through bolts and nuts, an annular groove is formed in the side face of a connecting end of the first pipeline, an annular shell matched and spliced with the annular groove is integrally formed in the side face of the connecting end of the second pipeline, an annular cavity is formed in the annular shell and extends to the inside of the connecting end of the second pipeline, an air bag is embedded in the annular cavity, an air pipe extending out of the upper face of the second pipeline is communicated with the air bag, and a switch valve is arranged on the air pipe.

As an improvement, a second annular cavity for filling the air bag is arranged on the bottom surface of the annular groove.

As an improvement, the inner side wall of the first connecting end of the pipeline is welded with a thread head, and the inner side wall of the second connecting end of the pipeline is provided with an internal thread in threaded connection with the thread head.

As an improvement, the material of the air bag is rubber.

As an improvement, a rubber pad is clamped between the first flange plate and the second flange plate.

Compared with the prior art, the utility model the advantage lie in: when the utility model is used, the arrangement of the annular groove, the annular shell and the air bag can lead the air bag to be inflated, thereby leading the end head of the air bag to bulge out, further leading the bottom surface of the annular groove not to have a gap, leading the connection between the first pipeline and the second pipeline to be more compact, leading the sealing performance to be better and avoiding the phenomena of water leakage and the like; the arrangement of the thread head can ensure that the connection between the first pipeline and the second pipeline is more stable and reliable.
