Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, an improved sealing ball valve comprises a valve body 1, a valve ball 2, a valve seat 3, a sealing structure 4 and an elastic component 5.
The two ends of the valve body 1 are connected with a detachable valve seat 3 through flanges, the valve seat 3 fixes the valve ball 2 in the valve body 1,
a valve stem (not shown) is passed through the upper portion of the valve body 1 and is detachably connected to the valve ball 2 in a conventional manner.
