Zusammenfassung:	The utility model provides a keep ware, control member subassembly and control valve for the control member of control valve. The flow path rate regulator allows the control member of control valve to be close very much the seating ring operation, reduces or get rid of the fluid area of restriction simultaneously, and its result greatly reduces the flow rate fluctuation to form more steady fluid between sealing element and sealing ring. As a result, the sealing element that is made by raw materials soft relatively can be used and not feared the damage that high flow rate arouses.
