Pneumatic valves have been widely used in the industry today, such as: power plants, chemicals, petroleum, petrochemical, municipal water, aviation and so on. Among them, the pneumatic unloading ball valve is a type of valve that has been widely used in recent years. It is mainly used to cut, distribute and change the flow of medium in the pipeline. The valve has the following characteristics:
The pneumatic ball valve has a simple structure, a light weight and a small volume, so it is very convenient to repair, and the sealing ring is easy to disassemble, replace and maintain at any time.
The pneumatic ball valve is very reliable in sealing and has small fluid resistance. When the valve is fully open or fully closed, the medium and the sealing surface are isolated between the ball and the valve seat. If the medium passes, the sealing surface of the valve will not be eroded. .
This type of valve has a wide range of industrial applications, ranging from millimeters to meters; it is easy to operate, and it can be opened or closed quickly, because the valve switch can be opened or closed as long as it is rotated 90 degrees.

One of the teapots worth mentioning is the long mouth teapot, which is commonly used in tea ceremony performances.
The long beaked teapots we saw for the performance are mostly bronze, and some are made of iron and tin, also known as the long spouted teapots. A tea maker with no flow is called a no flow pot, which can also be slightly raised; Short flow kettle --- a teapot with the spout water outlet separated from the chamber within three inches; Medium flow kettle --- the distance from the water outlet to the kettle chamber is about three inches to two feet; The teapot whose spout is more than two feet away from the pot cavity is called a long flow pot. In ancient times, the spout of Changliu Pot was usually three feet long, which is why the commonly known "one meter long pot" came into being.
