Both ends of the main pipe 1 are water outlets 11. The inner side wall of the branch pipe 2 is provided with a buffer mechanism 3 for buffering the fluid entering from the water inlet 21. Fluid is introduced into the branch pipe 2 from the water inlet 21, and the impact force and the flow speed of the fluid are weakened through the buffer mechanism 3, so that the condition that turbulent flow is generated when the fluid in the branch pipe 2 flows to the main pipe 1 is reduced, and the noise in the tee pipe is further reduced.

Referring to fig. 1, the buffer mechanism 3 includes a mounting seat 31 screwed to the inner side wall of the branch pipe 2, a buffer rod 32 slidably disposed through the mounting seat 31, and a compression spring 33 coaxially sleeved on the buffer rod 32, wherein a buffer portion 4 is fixed at one end of the buffer rod 32 facing the water inlet 21, and when fluid is introduced into the water inlet 21, the fluid compresses the compression spring 33 through the buffer portion 4, so as to weaken the impact force of the fluid.

Referring to fig. 2, the mounting seat 31 includes a truncated cone-shaped baffle shell 311 and a cylindrical fixing shell 312, and one end of the baffle shell 311 having the largest diameter is fixed to one end of the fixing shell 312 facing the water inlet 21.

An inlet 3111 is formed at an end of the baffle housing 311 away from the fixed housing 312, and a center of the inlet 3111 and a center of the water inlet 21 are located on an axis of the buffer rod 32.

Referring to fig. 2, a plurality of water holes 3112 are formed around the central axis of the baffle housing 311 on the side surface of the baffle housing 311. The outer side wall of the stationary case 312 is screw-coupled with the inner side wall of the branch pipe 2. The center of the fixed case 312 is provided with a fixed ring 5, and the outer side wall of the fixed ring 5 is connected to the inner side wall of the fixed case 312. The buffer rod 32 is slidably connected to the inner wall of the fixed ring 5 on the circumferential side thereof, and the buffer portion 4 is located in the baffle housing 311 and abuts against the inner wall of the baffle housing 311. One end of the compression spring 33 abuts against the buffer 4, and the other end is fixed to the side of the fixed ring 5 facing the water inlet 21.

The fluid flowing to the main pipe 1 in the branch pipe 2 is firstly buffered through the flow blocking shell 311 and the buffering part 4, then is buffered for the second time through the flow blocking block 6, and finally is buffered for the third time through the flow dividing block 7, and the flow speed and the impact force of the fluid reaching the main pipe 1 after being buffered for the third time are smaller than those of the fluid entering from the water inlet 21, so that the condition that turbulent flow is generated when the fluid in the branch pipe 2 flows to the main pipe 1 is reduced, and the noise in the tee pipe is further reduced.
