Detailed Description

Specific embodiments of the present utility model will be further described with reference to the accompanying drawings.

1-2, The water-activating three-way assembly 1 comprises a water inlet 4, a water outlet 5, a side water outlet 6 and a valve core 2, wherein a plug 3 is arranged in the valve core 2, the valve core 2 is blocked by the plug 3 when the water flow of the water inlet 4 is small, the valve core 2 is closed, when the water flow of the water inlet 4 is large, the plug 3 is flushed by the water flow, the valve core 2 is opened, and the water flow flows out from the water outlet or the side water outlet 6.

A columnar plug movable groove 9 is arranged in the valve core 2.

The plug 3 is an umbrella-shaped plug 3, the umbrella-shaped plug 3 comprises a plug cover 7 and a plug column 8, and the plug column 8 moves in a plug movable groove 9.

The valve core 2 comprises a spring 10, and the spring 10 is sleeved outside the plug movable groove 9 and the plug column 8, so that the plug 3 has certain resistance when being opened. The plug 3 plugs the valve core 2, the spring 10 stretches when the valve core 2 is closed, water flows towards the plug 3, and the spring 10 compresses when the valve core 2 is opened.

The water inlet 4 is arranged below the water outlet 5. The water inlet 4 and the water outlet 5 are on the same vertical line to form a straight pipe.

The side water outlet 6 is located on the side above the valve core 2. The joint of the side water outlet 6 and the straight pipe is a cambered surface.

The specific use process of the tee joint assembly 1 is shown in fig. 3-8, and is specifically as follows:

The tee assembly 1 is connected with a vertical pipe 11 and a branch pipe 12, wherein a water inlet 4 of the tee assembly 1 is connected with the vertical pipe 11, one end of the branch pipe 12 is connected with a side water outlet 6 of the tee assembly 1, and the other end is connected with the vertical pipe 11. The branch pipe 12 is also provided with a branch pipe tap 13.

When the water inlet 4 flows in a small amount as shown in fig. 3 and 4, the plug 3 plugs the valve core 2, the valve core 2 is closed, and almost all water flows to a loop formed by the branch pipes 124. Because the pressure requirement is not met, the valve body is closed.

As shown in fig. 5 and 6, when the water flow at the water inlet 4 is large, the water flow flushes the plug 3, the valve core 2 is opened, the water flow flows from the water inlet 4 to the water outlet 5 through the valve core 2, i.e. most of the water flow flows out through the vertical pipe 11, and the water flow at the branch pipe 12 circulates according to the venturi principle.

As shown in fig. 7 and 8, when the water flow at the water inlet 4 is large, the water flow flushes the plug 3, the valve core 2 is opened, the branch pipe tap 13 is opened, namely, the loop branch pipe tap 12 is used, the water flow at the water inlet 4 directly flows out from the branch pipe tap 13, and meanwhile, the water flow at the water inlet 4 flows out from the branch pipe tap 5 through the valve core 2. The water flow is divided into two paths to flow into the branch pipes 12, the branch pipes 12 can be provided with small-diameter pipelines, the pressure loss of the loop branch pipes 12 is low, and the pressure loss is beneficial to the use of the pipe diameters and the booster pumps.
