Based on analysis of the current state of the flow pattern modeling abroad and at home, explains the meaning of the mathematical simulation of the flows in the valve.(2) Comparing flow simulation data of jet pump with its experimental one, the feasibility and reliability of FLUENT used for flow simulation are proved.(3) Based on the characteristic of valves, the fluid field analysis of specific ring-spray type flow-adjustable is finished. The valve structure is optimized to meet the need, which makes it have such advantages:(1)smaller vortex area and faintish vortex intensity, so the vibration of vortex is controlled effectively;(2)the pressure is distributed more equality, the transition area is larger.

In normal fisher valve repair in general less damage to the implementing agencies fisher valves mainly in fisher sealed valve body and outer sealing maintenance organizations according to Jiangyin Oulei Si understanding fisher control valve sealed agencies and organizations outside the sealed according to the use of fisher control valve selection of different operating conditions change so to do maintenance on the essential Fisher control valve of the valve seal body of the fisher should be very understanding and to the maintenance of the Fisher control valve selection to do with confidence thus it will help Fisher control valve repairs!

在正常fisher阀门维修中，一般fisher阀门执行机构损坏较少，主要集中在fisher阀门内密封机构及外密封机构的维修上，据江阴市欧雷斯了解， fisher控制阀门的内密封机构及外密封机构、根据fisher控制阀的使用工况变化而选型不一，因此要做好Fisher调节阀维修就必需对fisher阀门的密封机构要相当了解，并且要对Fisher调节阀维修的选材做到胸有成竹，由此才有助于Fisher调节阀维修的工作！
