Valve type and principle-Plug valve

Plug valve, also called cock.The plug valve is rotated around the center line of the valve body by the plug body to achieve the purpose of opening and closing.Its role is to cut, divide and change the flow direction of the medium.The structure is simple, the size is small, only 90 degrees of rotation is required during operation, and the fluid resistance is not large.The disadvantage is that the switch is laborious, the sealing surface is easy to wear, and it is easy to get stuck at high temperature, which is not suitable for adjusting the flow rate.
