Structure composition:
Three piece clamp ball valve is composed of three sections of valve body with bolts in the middle.The valve can be fully opened or closed by turning the ball 90 degrees. It is usually used to make high pressure ball valve.
It is used to cut off or connect the medium in the pipeline. The valve seat adopts the elastic sealing structure, which makes the opening and closing easy and the sealing reliable.
Working principle :
The three piece quick mounting ball valve has the action of rotating 90 degrees. The plug body is a ball with a circular through hole or channel passing through its axis. Ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque to close tightly.
Features :
1. The clamp connection is easy to assemble and disassemble, and is suitable for the working conditions that need to be cleaned frequently.
2. It is easy to install and can be installed in any position of the pipeline in any direction.
3. The channel in the valve body is smooth and smooth, which can transport viscous fluid, slurry and solid particles.
4. It can be equipped with pneumatic, electric and other driving mechanisms to realize remote control and automatic operation.
5. Due to the good self-lubricating property of PTFE and other materials, the friction loss with the ball is small, so the service life of the ball valve is long.
Application:
suitable for water, steam, oil, nitric acid, acetic acid and other media.
