Water draining tee capable of generating rotational flow

Abstract

The invention relates to a water draining tee capable of generating rotational flow, which is connected into a whole by a vertical pipe body and a side pipe body; the side pipe body is spiral downwards at the right and is communicated with the right side of the vertical pipe body; the vertical pipe body is formed by a cylindrical pipe, a conical pipe and a bell mouth of an elastic sealing ring; the large mouth end of the conical pipe is connected with the lower end of the cylindrical pipe, and the inner diameter and the wall thickness of the large mouth end of the conical pipe are the same asthose of the cylindrical pipe; a small mouth end of the conical pipe is connected with the bell mouth of the elastic sealing ring, and the inner diameter and the wall thickness of the small mouth endof the conical pipe are the same as those of the bell mouth of the elastic sealing ring; a spiral guide vane is arranged on the conical pipe along the dextrorotation of the inner wall; a groove is arranged in the middle of the bell mouth of the elastic sealing ring and is internally provided with the elastic sealing ring; a side rotary pipe of the side pie body is spiral downwards at the right and is communicated with the right side of the cylindrical pipe, and the wall thickness of the side rotary pipe is the same as that of the cylindrical pipe; the included angle between the centre line ofthe side pipe body and the center line of the vertical pipe body is alpha, and the included angle between a guide inclined plane of the side pipe body and the center line of the vertical pipe body isgamma; the joint between the bottom of the side pipe body and the vertical pipe body takes on u-type transition, so that the water circulating capability of a water draining system is improved, and the water draining noise can be reduced.

Description

(1) Technical field: [0001] The invention relates to a drainage tee capable of generating swirling flow. The drainage tee is a component of a building drainage system, which is suitable for connecting a drainage horizontal branch pipe and a drainage standpipe, and belongs to the technical field of building water supply and drainage. (two) background technology: [0002] The eccentric tee is currently used to connect the drainage lateral branch pipe and the drainage riser pipe, so that the drainage water flow spirals down along the riser pipe wall in a swirl state. However, in actual engineering, the eccentric three-way swirl effect is not good, and the air pressure fluctuation and drainage noise of the drainage standpipe are still very large. (3) Contents of the invention [0003] 1. Purpose [0004] The purpose of the present invention is to provide a drainage tee that can generate swirling flow, which overcomes the deficiencies of the prior art, can improve the swirl ef...
