Description
Technical field
The utility model is related to valve field, more particularly to a kind of spherical valve core.
Background technology
The industrial circles such as oil, chemical industry, electric power, metallurgy, building materials are used to convey the pipe of liquid, gas and solid blending agent
Road generally needs to use valve to be adjusted and turn off.
Existing ball valve typically using two logical core structures, is provided with the medium channel for flow of media in core, be situated between
Matter passage runs through the opposite sides of core, and forms upstream passageway mouthful with downstream passage mouthful.During valve wide open, the medium of core leads to
Road connects upstream and downstream completely, and valve pocket not with upstream or communicating downstream, the medium in valve pocket cannot be discharged into downstream tube
In road.
During valves half open, core rotates, while medium channel connection upstream medium and downstream media, the one of valve pocket
Subregion is connected by upstream passageway mouthful with the gap between valve seat entrance, and another part region is by downstream passage mouthful and valve
Gap connection between seat outlet, but this two parts region of valve pocket but exists without directly connection due to core, deposits
In many dead bands, medium is easy to be deposited in these dead bands after flowing into valve pocket.
When valve is fully closed, upstream passageway mouthful and downstream passage mouthful in core are all transferred to valve pocket, the opposite sides of core
Valve seat entrance and valve seat outlet can completely be blocked, so as to block medium upstream and downstream, core opposite sides is used to seal
The region of valve seat entrance and valve seat outlet is located between core upstream surface passway and downstream passage mouthful, and now valve pocket does not have
With upstream or communicating downstream, the medium in valve pocket cannot be discharged into downstream line, still be deposited in valve pocket.
This ball valve easily causes blocking due to frequent deposition medium in valve pocket, causes ball valve not open or close not
It is disconnected, or even the phenomenon such as locking, so as to cause valve service life not long, the stream of semi-solid medium and solid dielectric is not applied to especially
Logical and shut-off；Again because valve pocket cannot completely be connected with upstream and downstream, medium is strong to core scouring force, core of easily wearing and tearing, significantly
Reduce the service life of core.
Utility model content
