2、 Tan property of ball valve: the ball of ball valve is Tan property
The ball and valve seat sealing ring are made of metal materials, and the sealing specific pressure is very high
The pressure of the medium itself cannot meet the sealing requirements, so external force must be applied
This valve is suitable for high temperature and high pressure media
Tan sphere is a tan groove at the lower end of the inner wall of the sphere to obtain tan
When closing the channel, use the wedge-shaped head of the valve stem to make the ball expand Kai and the valve seat tightly to seal
Before rotating the ball, loosen the Kai wedge head, and the ball will return to its original shape, resulting in a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface

3、 Installation of aluminum plastic pipe ball valve:
1
Screw the side cap at one end of the valve Kai and take out the snap ring

2
Put the removed side cap and snap ring into one end of the pipe in turn

3
Please use the hole expanding and rounding device to adjust the Xing, and then insert the serrated sealing end of the valve into the pipe with force, with Tao into the side cap and one end of the snap ring, all the way to the bottom; When inserting, pay attention not to shift the sealing ring

4
Connect and tighten the side cap and snap ring of Kai with the valve body again
When tightening, one wrench is clamped on the valve, and the other wrench is used to tighten the side cap until it is tightened
