Abstract

The invention discloses a heavy-duty one-character locking ball valve in the technical field of ball valves. The ball valve comprises a valve body, wherein a valve rod is arranged in the inner cavityat the upper end of the valve body; a rotary screw rod is connected in the top of the valve rod in a movable and inserted manner; a rotary handle is arranged at the top of the rotary screw rod; a movable top rod is connected in the inner cavity of the rotary screw rod in a movable and inserted manner; insert blocks are arranged on the inner walls of four sides of the inner cavity of the valve rod;a limiting hole is formed in one end of each the insert block far away from the inner wall of the valve rod; a clamping device is fixedly arranged on the inner wall of the rotary screw rod; the clamping device comprises a fastening sleeve ring fixedly formed in the inner wall of the rotary screw rod; movable plate blocks are uniformly arranged on the inner walls of four sides of the fastening sleeve ring; spring rods and limiting rods are arranged at one end of each the movable plate block close to the inner wall of the fastening sleeve ring; and the other end of each the limiting rod penetrates through the rotary screw rod and extends to the inner side of each the limiting hole. The ball valve can be conveniently fixed; and meanwhile, the movable top rod can be directly pulled out duringreplacement and maintenance, so that disassembly and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a heavy-duty inline lock ball valve. Background technique [0002] The ball valve is one of the tools commonly used in life to install on the top of the water pipe to control the flow of water. There are various types of ball valves. Among the ball valves, the heavy-duty one-word lock ball valve is generally fixedly connected with the valve stem and the rotating screw, and the rotating screw is locked with the valve stem, so that the valve stem can rotate during the process of rotation. more stable. However, during the use of this heavy-duty inline lock ball valve, if the ball valve is damaged, it is inconvenient to disassemble and difficult to replace and repair. To this end, we propose a heavy-duty word lock ball valve. Contents of the invention [0003] The purpose of the present invention is to provide a heavy-duty in-line lock ball valve to solve the problems raised...
