Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a sealing rotary ball valve connection piece capable of preventing liquid leakage. Background technique [0002] The rotary ball valve has the functions and advantages of butterfly valve, hemispherical valve, gate valve and globe valve at the same time, and has its own completely unique powerful functions and advantages. Small size, light weight, convenient transportation, installation, maintenance and overhaul, reliable operation. [0003] At present, the mainstream rotary ball valve has the problem of difficulty in opening and closing. When switching the rotary ball valve, it is often carried out by turning the control handle. However, manual rotation is often required when turning the rotary ball valve. Manual rotation is difficult and is not conducive to practical use. Contents of the invention [0004] The object of the present invention is to solve the shortcomi...
