Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a filterable stop valve body. Background Art

[0002] The opening and closing parts of the stop valve are plug-shaped discs, and the sealing surface is flat or conical. The disc moves linearly along the center line of the valve seat. The movement form of the valve stem (general name: dark stem) is also a lifting and rotating rod type. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Therefore, this type of shut-off stop valve is very suitable for cutting off or regulating and throttling. Since the valve stem opening or closing stroke of this type of valve is relatively short and has a very reliable cutting function, and since the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for regulating the flow rate.

However, the stop valve is not convenient for maintenance and replacement of the filter device, resulting in blockage of the filter device affecting the flow rate of water, and also reducing the filtering effect of the filter device, which is inconvenient for users to use and reduces the practicality of the stop valve. Therefore, a filterable stop valve body is proposed to solve the above-mentioned problems. Utility Model Content
