Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Please refer to fig. 1-4, the utility model provides a pipeline connection structure based on hydraulic engineering, it includes the trunk line 1 that supplies water to flow and connects the shutoff stopper 2 of adjacent trunk line 1. The main pipeline 1 comprises a pipe body 11, and two ends of the pipe body 11 are respectively connected with a sealing end 12 and a plugging end 13; the sealing end 12 and the plugging end 13 can be partially connected with the pipe body 11 by a detachable connection manner such as a threaded connection, so as to be convenient to combine and connect for use. As shown in FIG. 1, the plugging end 13 is flared, and the outer diameter thereof is gradually increased from the position close to the pipe body 11 to the end; the internal diameter of this sealed end 12 is greater than the biggest external diameter of end 13 of plugging in, is provided with annular separation blade 123 in sealed end 12, and when two adjacent trunk lines 1 were connected, end 13 of plugging in can stretch into to the sealed end 12 of another trunk line 1 in, and end 13 of plugging in contradicts on annular separation blade 123, sets up by internal thread section 122 at the oral area of sealed end 12. As shown in fig. 2, the middle of the plugging plug 2 has a through hole 21, the plugging plug 2 is sleeved on the tube body 11, the tube body 11 is slidably connected with the through hole 21, the plugging plug 2 has an external thread section 22, and the external thread section 22 is in threaded connection with the internal thread section 122.

The tube body 11 is sleeved with a sealing rubber ring 3, and the sealing rubber ring 3 is positioned between the sealing plug 2 and the plugging end 13.

During the use, as shown in fig. 3-4, when two adjacent main pipelines 1 are connected, the plugging end 13 of one main pipeline 1 extends into the sealing end 12 of the other main pipeline 1, the end of the plugging end 13 is abutted against the annular retaining sheet 123, the sealing plug 2 is screwed to the inner thread section 122 of the sealing end 12, the sealing rubber ring 3 is tightly pressed on the plugging end 13 by the end of the sealing plug 2, and the sealing rubber ring 3 is tightly attached between the plugging plug 2 and the plugging end 13, so that the waterproof and seepage-proof effects are achieved.
