More Information
Summary:The utility model relates to a valve, particularly a fluid valve of low flowing resistance. The low flowresistance guide stop valve mainly comprises a valve body, floating plugs, a valve hood, etc. Slope angles are formed among central axes of the floating plugs and the direction of the fluid motion, a combinatorial sliding sleeve used for controlling the reciprocating motion of a double-threaded screw is positioned outside the floating plugs. A tight head of the big floating plug, an upper rubber and a lower rubber of the big floating plug are match with the big floating plug to work, the cylinder wall of the big floating plug is provided with a diversion hole, and an uplifting claw and the lower rubber of the small floating plug are positioned at the front end of the small floating plug. The utility model has the advantages of simple structure, small flow resistance coefficient and long service life.
