Valve running thrust which represents 90% of the travel of the valve stem can be determined by adding stem load and stem packing friction.
|
|
|
阀门运行推力只是阀门阀杆行程力的90%，因此测算阀门推力时，要加上阀杆负载和阀杆填料摩擦力。 |
|
Valve should be tighten with O ring rubber with max. 25% compression.
|
|
|
阀门的密封需通过“O”型密封圈实现，密封圈最大压缩量不允许超过25％。 |
|
Valve size and figure number.
|
|
|
阀门通径和型号。 |
|
Valve size, figure number or description.
|
|
|
阀门通径，型号或规格说明。 |
|
Valve tightening fixture is special for each DN and should be easily replaceable.
|
|
|
被测的每种规格阀门的紧固件必须保证轻松可拆换性。 |
|
Valves are also furnished with solid wedge discs that have proved successful in millions of applications.
|
|
|
这种阀门也配置实心楔形阀瓣，并经过几百万个实际应用的成功考验。 |
|
Valves are not to be used near a reciprocating air compressor.
|
|
|
阀门不能用在往复式空气压缩机附近的地方。 |
|
Valves can be supplied with an interlock system.
|
|
|
可以为阀门配置一个联动装置系统。 |
|
Valves may be sized to match existing lines, but swing check and stop-check valves should also be sized according to flow conditions for maximum service life.
|
|
|
可以根据现存的相匹配的管线来确定阀门通径，但是旋启式止回阀和截止止回阀还应该根据最大限度延长使用寿命的流体状况来确定阀门通径。 |
|
Valves requiring processing in the Clean Room should first be assembled prior to cleaning, subjected to cracking and reseat pressure, and flow tested in the flow outside the clean environment.
|
|
|
要求在无尘室中完成各工序的真空管首先要在清洗之前要将其组装起来,再使其承受裂化和复位压力,接着在清洁的环境下进行流动测试. |
|
Valves should be installed in the (stem) vertical position with the pipe flow horizontal only. For installations other than this, please consult factory when ordering.
|
|
|
阀门应该只能安装在水平流向的管线上，其阀杆应该垂直向上。如果需要其它方式的安装，请在订购阀门时咨询工厂。 |
