A locking welding ball valve is a specialized type of welding ball valve that controls the valve through a magnetic locking mechanism, primarily used to prevent unauthorized operation and ensure pipeline safety. Its core features include magnetic control, anti-misoperation design, and a multi-seal structure, suitable for high-safety-demand scenarios such as gas and heating systems.

Operating Principle

The lockable welding ball valve is controlled by a magnetic lock head to open and close the internal closure. The lock head side has a spring hole and a magnetic ball, which must be inserted into the "C" shaped slot on the lock head using a key. The valve can only be operated after the magnetic lock is unlocked. When closed, the magnetic lock locks in place to prevent the valve from being arbitrarily opened or closed.

Structural Features

Magnetic Locking Mechanism: The locking function is achieved through a spring, lock cylinder, and magnetic ball. The key must match the magnetic properties of the lock cylinder to unlock.

Sealed Design: The valve stem is equipped with a combination of PTFE sealing rings and O-rings, ensuring zero leakage.

Material Matching: Valve body and pipeline materials are identical to avoid uneven stress or deformation.

Applicable Scenarios

Primarily used in urban gas pipelines, centralized heating systems, and industrial applications requiring anti-misoperation and anti-corrosion protection, such as shipboard and steel mill fluid control systems.
