One Piece Ball Valve

Zhejiang Dafugui one piece ball valve structure Introduction

The term "one piece ball valve structure" refers to a type of ball valve that has a unified valve body and valve core. Unlike multi-segment structured ball valves, this design is simple, compact, and lightweight. It is commonly used for pipeline switching and flow control applications and is extensively utilized in various industries, including petroleum, chemical, natural gas, and water treatment.

Zhejiang Dafugui one piece ball valve structure Feature And Application

The ball in a ball valve is designed to be elastic and is usually made of a metal material. The sealing ring between the ball and valve seat is also made of metal, and can withstand high pressures. However, in some cases, an external force may be necessary to achieve a proper seal, particularly for V-type ball valves that are designed for high temperature and high pressure media.

To ensure a proper seal in an elastic sphere, a groove is typically carved into the lower end of the inner wall of the sphere to provide the necessary elasticity. When the channel needs to be closed, the wedge head of the stem is used to expand the ball and press it against the seat, creating a seal. To reopen the channel, the wedge head is loosened, allowing the ball to return to its original shape. This creates a small gap between the ball and seat, which reduces friction and operating torque on the sealing face.
