中央管件阀门研究院进行了改善闭路阀流阻特性的研究工作。在进行带卸压阀的闭路阀研究工作中,其中之一是研究阀体的流道。阀体关闭件流道的研究是在14个可分式模型上进行模拟试验的。模拟的流道公称通径是Dy=50、100、150毫米。各种形状流道的模型用木头来制造。在模型流道内镶入流道内径为n=I.12～I.28协的金属座。每
Central Pipe Valve Institute conducted a study to improve the characteristics of closed-circuit flow resistance of the valve. One of them is to study the flow path of the valve body during the research on the closed-circuit valve with pressure relief valve. The study of the valve closure flow passage was simulated on 14 separable models. The simulated runner nominal diameter is Dy = 50, 100, 150 mm. The various shapes of runner models are made of wood. In the model flow path set in the runner diameter n = I.12 ~ I.28 Association of the metal seat. each
