Description

Concealed ball valve

Technical Field

The utility model belongs to the technical field of valves, and relates to a concealed ball valve.

Background

Ball valves are used mainly to cut off, distribute and change the direction of flow of a medium and are widely used in various industries. Ball valves generally comprise a valve body, a ball core and a valve rod, wherein the ball core and the valve rod are arranged in the valve body, and the ball core is driven to rotate by the valve rod to realize communication or cutting off. Conventional ball valves are directly connected to a pipe to be exposed, but as the material level is continuously increased, people begin to consider that the ball valve is buried in a wall body, and only a handle is exposed to the outside, so that indoor neatness is improved. The traditional ball valve rod is shorter, the buried requirement cannot be met, and therefore, the concealed ball valve is designed. The length of the valve rod adopted in the concealed ball valve is longer, the valve rod can extend out of the wall body after the valve body is embedded into the wall, and meanwhile, the connecting sleeve on the valve body is sleeved outside the valve rod and covers the position of the valve body embedded into the wall body by adopting the decorative cover. However, the opening direction of the existing concealed ball valve is fixed like the traditional ball valve, and different handedness cannot be met, so that the applicability is not enough.
