查询词典 casing spool

Through the valve to reduce the diameter to increase the opening work, the specific ways:① replace a file of small-caliber valve, such as DN32 replaced DN25;② body does not change, the replacement of small diameter spool valve seat Block.

通过把阀的口径减小来增大工作开度，具体办法有：①换一台小一档口径的阀，如DN32换成DN25；②阀体不变更，更换小阀座直径的阀芯阀座。

Figure 2-30 is a three commonly used control valve sleeve sleeve diagram, due to changes in hole size is different spool move When the flow area is also different, in order to achieve the required flow characteristics.

图2—30是三种常用套筒控制阀的套筒示意图，由于开孔面积变化不同，阀芯移动时，流通面积也不同，从而实现所需流量特性。

The percentage of linear and so quick Figure 1 Three common control valve sleeve sleeve diagram Interchangeability of parts from Ball Valves the valve to see some adjusting mechanism trim can be easily replaced and maintained, for example, the sleeve valve sleeve can be easily replaced to achieve different flow characteristics; top and bottom-oriented trim can be easily turn the spool and the valve seat to achieve positive and anti-body to replace the valve body to achieve the air to open the way to replace gas off; valve isolation valve can be easily dismantled for the seat replacement and cleaning.

快开 线性等百分比图1 三种常用套筒控制阀的套筒示意图从阀内件的互换性看，一些调节机构的阀内件可方便地更换和维护，例如，套筒阀可方便地更换套筒实现不同流量特性；顶底导向的阀内件可方便地翻转阀芯和阀座来实现正体阀与反体阀的更换，从而实现气开和气关方式的更换；阀体分离阀可方便地拆卸，用于阀座更换和清洗。

When the rotating valve changes its direction, the flow area of valve will gradually change to ensure that the transition process has a reasonable time to change. Special structure of The spool can ensure that the flow curve of any change to the two-cylinder has the good convergence, and thereby the shock of exchange is reduced.

转阀在换向过程，其阀口的过流面积能逐渐变化，保证了换向过渡过程有一个合理的换向时间；阀芯的特殊结构，保证任意两缸换向时的流量曲线的良好衔接，从而减少换向冲击。

Equal percentage flow characteristics - ideal for the spool stroke of equal increments, changes in flow rate for the trip can be expressed as changes of flow in a constant percentage.

等百分比流量特性－理想地，对于阀芯行程的相等增量，流量对于行程的改变可以表示为在改变时的流量的一个恒定的百分比。
