At valve repair, import relief valve repair complex; import relief valve, control valves are used the body parts of the opening gate to regulate the flow of medium, medium pressure to lower pressure after the valve simultaneously with the role of regulation headstock of the opening piece, so that after the pressure valve to maintain at a certain range, the inlet pressure at the ever-changing circumstances, to maintain outlet pressure at setting the framework of the back to protect its pipelines, equipment, pressure, temperature stability ..................

在阀门维修中进口减压阀维修比较复杂；进口减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后面管道、设备的压力、温度的稳定

By combining virtual instruments technique with the test technique of electro-hydraulic servo valve, the test system of electro-hydraulic servo valve based on virtual instruments has been developed by the graphics software-LabVIEW6.1. The test principle and method of electro-hydraulic servo valve were discussed in this dissertation. The experimental results on a Moog servo valve demonstrate that the design of electronic-hydraulic servo valve test system is valid.

本文将虚拟仪器技术和电液伺服阀性能测试技术结合起来，利用图形化软件工具—LabVIEW，研制开发出了基于虚拟仪器的电液伺服阀性能测试系统，对电液伺服阀的静、动态特性测试原理和方法进行了讨论和研究，以MOOG伺服阀为测试对象进行了静态特性测试和试验结果分析，验证了所开发的电液伺服阀测试系统设计方案的合理性。

This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.

本项目是一种新型结构的直动式溢流阀，采用动压反馈原理，在普通直动式溢流阀阀芯上增加一反馈腔，当阀口溢流时，阀口的液压力与反馈腔液压力和弹簧力相平衡，从而可以减小弹簧的刚度，等于增设了一根液压弹簧，使其和机械弹簧一起工作，以达到减小阀口压力变化范围的目的。

Methods:43 patients including 10 with mitral stenosis associated aortic regurgitation, 12 with mixed mitral valve lesions and 21 with mixed mitral valve lesions and combined with aortic regurgitation were studied.MVA determinded by (1) two -dimensional echocardiography with a cross-sectional area in the short-axis view (2DE),(2) pressure half-time using formula of 220/PHT,(3) color Doppler flow imaging with a jet cross-sectional area in the short-axis view with planimetry,(4) CDFI with a color jet width at the mitral valve orifice in the apical four-chamber view and long-axis view, assuming an elliptic mitral orifice, compared with the orifice area of excised mitral valve during mitral valve replacement.

材料与方法∶分别用二维超声(2DE)、压差减半时间、彩色多普勒二尖瓣口血流截面积和椭圆形面积法测定43例风湿性心脏病二尖瓣狭窄拟行人工瓣置换术患者的MVA，其中合并主动脉瓣反流 10例，合并二尖瓣反流 12例， 21例，并与手术标本的实测面积相比较。
