Analysis of Misunderstanding Range in Rated CV of Reduced Port Sleeve Control Valve
The definition of rated Cv value of Port Sleeve control valve is introduced.Mathematical mode calculation analysis of rated Cv value for reduced port sleeve valve is introduced with emphasis.After CFD fluid analysis,laboratory flow testing and numerical simulation theory calculations,the flow capacities of partial reduced port sleeve valve and full port sleeve valve are compared.It is found that for port sleeve valves with the same valve core size but different valve diameters,the flow capacity of the large reduced port sleeve valve is superior to that of the small full port sleeve valve.When selecting some reduced port sleeve valve,attention should be paid to the misunderstanding range in Cv calculation.It is to avoid selecting control valves with too small relative opening aperture.
