Abstract
This invention has an objective of offering a spherical valve, which has a valve chamber with a space enough for receiving a valve therein, and letting the valve move smoothly therein. A connecting member respectively formed at two sides of the valve chamber is for connecting with exterior tubes, having an annular projecting portion with a comparatively large thickness so that shrinking occurring during inject-forming process of the body may be offset by the annular projecting portions so that the valve chamber may not be deformed so that the valve may move smoothly in the valve chamber.
