Description

Technical Field

[0001] The present application relates to the technical field of plastic valve bodies, and in particular to a high-platform ball valve. Background Art

[0002] A valve is a component that realizes opening or closing by controlling the movement of a valve core. Valves are mostly used in pipeline systems. The materials of valve bodies are diverse. With the progress of material technology, plastic valve bodies are widely used in plastic pipeline systems for water supply and other industrial fluids due to their advantages such as light weight, corrosion resistance, integratable connection with plastic pipelines, and long service life.

[0003] The high-platform ball valve is one of the most common valve bodies. A valve stem is connected to the spherical valve core, and the upper end of the valve stem passes through the valve body and is connected to an actuator or a handle. Bolt holes are provided on the valve body connected to the actuator and are connected to the mounting plate of the actuator through the bolt holes; an angle limiting structure for the handle is provided on the valve body connected to the mounting handle to prevent the spherical valve core from rotating excessively. However, the valve bodies for mounting the actuator and the handle are not interchangeable.

[0004] In the prior art, there are some valve bodies that can mount a handle and an actuator. For example, a Chinese patent with the application publication number CN112377661A and the publication date of February 19, 2021 discloses a fixed ball valve with an interchangeable structure for a handle and an actuator, including a connecting support plate. A first step, a second step, a third step, and a fourth step are sequentially arranged from top to bottom at the center position of the connecting support plate. A limiting plate is connected to the top end of the second step. A connecting through hole and an ISO adapter plate hole are provided at the top end of the first step. A bearing is provided at the top end of the fourth step. The connecting through hole and the ISO adapter plate hole are arranged on the same circle. A valve stem passes through the center positions of the bearing and the limiting plate, and a threaded hole is provided at the center position of the top end of the valve stem.

[0005] In the above, by providing multiple steps on the connecting support plate and a limiting plate on the steps, the angle of connecting the handle is restricted by providing an inferior arc groove on the limiting plate. At the same time, it can also be used by connecting an actuator through the connecting through hole. Regarding the above related technology, the inventor believes that although the installation problems of the handle and the actuator can be solved in this application, the installation of the handle uses an inferior arc groove and a key matching for limiting, which affects the use effect; at the same time, this application requires re-designing and mold opening, increasing the production cost.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:
