The key to this valve is in the flexible reinfoced rubber sleeve - the valve's only wetted part.

其主要原因就在于这种阀门内部的弹性强化套管，也就是这种阀门唯一与流体接触的部件。

When the single-seat valve is less stable, the replacement valve into the sleeve stability will be improved.

当单、双座阀稳定性较差时，更换成套筒阀稳定性一定会得到提高。

This structure effectively compensation between the sleeve and the valve stem of the tolerance zone and in the media of elastic deformation under pressure to resolve the two-way valve in the transmission medium of exchange that exist in the process of sealing problems.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

This structure effectively compensate for the tolerance between the sleeve and the valve stem in the medium zone and the elastic deformation under pressure to solve the two-way valve in the transmission medium of exchange that exist in the process of sealing problems.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

Why single sleeve valve replacement, the two-seat valve has failed to do?

为什么套筒阀代替单、双座阀却没有如愿以偿？

This structure effectively compensate for tolerance between the sleeve and the valve stem in the medium band and elastic deformation under pressure to solve the two-way valve in the process of exchange of the medium transport sealing problems exist.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

Why replace the single sleeve valve, two-seat valve has not got his wish?

为什么套筒阀代替单、双座阀却没有如愿以偿？

Of which the slide valve position feedback ﹑ two dry-type most widely used electro-hydraulic servo valve.

其中以滑阀位置反馈﹑两级乾式电液伺服阀应用最广。

First of all, the relationship between strain and pressure of slide valve membrane sensor under different loads was analyzed and simulated by using ANSYS software; then an experimental device was designed and used to calibrate the slide valve membrane sensor.

首先采用ANSYS软件模拟了阀瓣膜传感器承受不同载荷下的应变与压力的关系；同时也设计了一套阀瓣膜传感器的标定实验装置，利用该实验装置对阀瓣膜传感器进行了标定实验。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
