What Are The Structures And Characteristics Of Three-piece Ball Valves?

The three-piece ball valve also has internal thread connection, external thread connection, and internal and external thread connection. The thread usually uses 55° tapered pipe thread, which has good sealing performance. So do you know what are the structure and characteristics of the three-piece ball valve?

The structure and characteristics of the three-piece ball valve are as follows:

The valve body of the three-piece ball valve is composed of a main valve body and two auxiliary valve bodies, so it is called a three-piece ball valve. After the ball core and the valve stem are installed in the main valve body, the auxiliary valve body is installed in the valve seat, and the main and auxiliary valve bodies are connected as a whole by bolts. Its ball core flow channel is also full-diameter.

The three-piece ball valve also has internal thread connection, external thread connection, and the internal thread usually uses 55° tapered pipe thread, which has good sealing performance. The external thread has a welding joint and can be welded to the pipeline. It is convenient to disassemble and assemble during maintenance, avoiding the need for a separate joint for the internal thread connection.

The main feature of the three-piece ball valve is that it can be maintained online, which is very convenient. Loosen the screws on the valve body and remove a bolt that passes through the main valve body.
