Description

Technical Field

[0001] This utility model relates to the field of discharge ball valve technology, specifically to a discharge ball valve with a different diameter and inclined rod. Background Technology

[0002] Discharge ball valves are commonly used on reactors and are installed flush against the inner wall of the reactor. In existing technology, the valve body of the discharge ball valve is typically fixed to the bottom flange of the reactor using bolts. Because the bottom flange needs to fit flush against the inner wall of the reactor, nuts must be installed on the back of the flange on the valve body. When tightening the nuts, workers need to bend over and use a wrench, increasing their workload. Furthermore, the back of the flange on the valve body has limited space due to the inclined valve stem, making it inconvenient to tighten the nuts, thus increasing installation time and reducing efficiency. Therefore, a reducing-diameter inclined rod discharge ball valve is proposed to improve installation efficiency. Summary of the Invention
