| Abstract: | In the regulating valve,the velocity of the medium have a huge damage to trims in the form of the impact force. After analyzing the working condition of the single - seat regulating valve, the working condition of the single -seat regulating valve is simplified to throttle orifice plate. It can get to know the impact force of the single - seat regulating valve under different opening from the mathematical model of single - seat regulating valve which is set up by using the momentum equation, Bernoulli equation and continuity equation. |
