Description

A kind of novel ball valve that may filter that

Technical field

The invention belongs to ball valve technical fields, and in particular to a kind of novel ball valve that may filter that.

Background technique

Ball valve is a kind of very common valve, by ball valve in standard is defined as: opening and closing element (sphere) is driven by valve rod, and The valve to rotate around the axis of valve rod.The circulation or cut-off of pipeline internal medium may be implemented by the rotation of sphere, Often with various impurity, excessive impurity can block pipeline, outlet etc., influence medium for example common water of medium in pipeline Normal supply, so needing to be filtered the medium in pipeline and will filter out the impurity come cleans out pipeline.

Although filter type ball valve currently on the market can be good at filtering out the impurity in channel in medium, but the ball In use for some time, filter to condense on the string bag has many impurity to valve, needs to clean or replace the filtering string bag, is unclamping end Gai Shi, the medium in discharge pipe can be flowed out along the closed exit of end cap institute, the waste of medium be caused, if in channel Medium be petroleum, natural gas etc industrial chemicals, also will cause environmental pollution, so the filter type ball valve is generally only applicable in In tapping channel is very short or tapping channel in there is no medium pipeline in, use scope is smaller.
