Description

Technical Field

[0001] The utility model relates to the technical field of valve manufacturing, in particular to a locking sleeve-type angle ball valve. Background Art

[0002] In industrial production, ball valves are driven by a valve stem and rotate around their axis. They can also be used for fluid regulation and control. Hard-seal V-shaped ball valves, with their V-shaped core and carbide-clad metal seat, provide strong shear forces, making them particularly suitable for media containing fibers and tiny solid particles. To enhance the strength of ball valves, angled ball valves with locking sleeves are often used.

[0003] In general, a ball valve is usually driven by the valve body and the valve stem, and rotates around the axis of the ball valve. However, the strength of this structure cannot be guaranteed, which can easily cause damage to the ball valve structure. A Chinese patent discloses an angle ball valve with application number "CN201820427961.4", which includes a ball valve body, a pipe joint and a core joint. The ball valve body is provided with a first connection end and a second connection end for the inlet and outlet of fluids. The pipe joint is detachably connected to the first connection end or the second connection end, and the core joint is detachably connected to the first connection end or the second connection end. When water is flowing in from the right, the pipe joint is connected to the first connection end, and the core joint is connected to the second connection end. When water is flowing in from the left, the pipe joint is connected to the second connection end, and the core joint is connected to the first connection end. During use, the relative installation positions of the pipe joint and the core joint on the ball valve body can be flexibly switched according to the actual water inlet conditions of the angle ball valve, thereby solving the problem of ordinary angle ball valves being restricted by right and left water inlet during installation, improving the flexibility of the pipeline system, improving assembly efficiency, and avoiding waste. However, this structure does not solve the problem that the ball valve body is easily damaged. However, this structure lacks a paint protection structure. Utility Model Content
