Abstract

The invention discloses a filter ball valve. The filter ball valve comprises a valve body, a bonnet, a valve rod, a hand shank and a valve ball. The hand shank is fixedly connected with the valve rod. The valve rod is rotatably connected with a locking nut. The valve ball is internally provided with a filtering device. The filtering device comprises a filter net, an upper sheath and a lower sheath. The filtering net is fixedly connected with the upper sheath and the lower sheath correspondingly. The upper sheath is fixedly connected with the valve rod. According to the filter ball valve, the structure is ingenious, the filtering effect is good, the changing for the valve body is slight, thus the changing for production equipments and the number of new molds are less required, the cost pressure of manufacturing enterprises is reduced, and enterprise production is facilitated.

Description

technical field [0001] The invention relates to a valve body, in particular to a filter ball valve. Background technique [0002] Ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. The ball valve itself is compact in structure, reliable in sealing, simple in structure and convenient in maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easily eroded by the medium, easy to operate and maintain, suitable for general working media such as water, solvent, acid and natural gas, and It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, and is widely used in various industries. The ball valve body can be integral or combined. At present, the ball valve with filtering function is provided with a filter cavity at a certain angle to the axis of the valve body channel between the valve ball ...
