Abstract
The utility model relates to a diameter variable connecting ball valve which comprises a valve body and a valve ball. A valve chamber is arranged in the valve body. The valve ball is arranged in the valve chamber. The valve body is provided with first threads. A medium circulation hole is formed in the valve ball. The aperture of the medium circulation hole is smaller than the diameter of the first threads. Through adoption of the method, the diameter variable connecting ball valve achieves spanning connecting and mounting due to the fact that the aperture of the medium circulation hole is not matched with the diameter of the connecting threads. Consequently, water supply and drainage pipelines and heating pipelines achieve diameter variable connecting of circulating media, diameter variable connectors are decreased, and cost is saved. Meanwhile, leakage pitch points of the pipelines are decreased. Through adoption of the design of a controllable switch, the diameter variable connecting ball valve brings convenience to use of users.
