您要查找的是不是：
- If the valve seat diameter is not known, the port diameter can be assumed to be the seat diameter for estimating purposes. 阀门阀座直径。如果不知道阀门阀座的直径,则可以将端口直径作为阀座直径进行估算。
- The valve seat diameter. 阀门阀座直径。
- The maximum differential pressure across the valve seat. 通过阀门阀座的最大压差。
- If the cage disengages prematurely, simply use the cage as a tool to screw the check valve seat from the valve body. 如果预先拆卸阀笼，就可以将阀笼作为工具从阀体上旋转止回阀阀座。
- The valve seat should be either very narrow or very wide, depending on the valve type. 阀门阀座可以很窄,也可以很宽,主要取决于阀门的类型。
- This feature also permits field repair of the valve seat without fear of misassembly by field mechanics. 此外,这种结构允许现场维修阀门阀座,不需要担心采用现场工具会导致错误安装。
- Globe valves are usually installed with the inlet below the valve seat. 安装截止阀时，通常把进口安装在阀座下方。
- Now generally used PTEE, EPDM and other material for the valve seat, so bubbles leakproofness good. 现一般均使用PTEE、EPDM等材料，为阀座，因此，气泡密封性佳。
- They are designed to provide a secondary seal in the event the cylinder valve develops leakage through the valve seat. 它们是设计用来在钢瓶阀门通过阀座产生泄露的情况下提供一个二次密封。
- Medium pressure increases toward the valve seat surface and oblique cone sealing surface squeezed more tightly, sealing the better. 正向介质压力增大时阀板斜圆锥表面与阀座密封面挤压越紧，密封效果越好。
- The results show that a part of the flow passage of the valve seat is occupied by the cavity under the valve head, leading to a decrease of flow rate. 研究结果表明：阀碟下方的空穴区占据了阀座喉部通流面积的一部分，使得有效的通流面积减小，影响了阀门的通流能力；
- Swing Check Valve bodies are ordinary hinge, there is a door the same as the free flap valve against the valve seat sloping surface. 旋启式止回阀有一介铰链机构，还有一个像门一样的阀瓣自由地靠在倾斜的阀座表面上。
- Up chamfer, down chamfer and working face must be correctly dressed so that the valve seat can acquire a longer service life. 气门座要获得高的使用寿命就必须对其上、下倒角和工作面进行适当的修整。
- When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat. 当手轮旋转到关闭位置，上阀杆推动横膈膜，横膈膜下垂，迫使下阀杆接触阀座。
- The valve saucer reed offers the continuous mechanical pressure,guarantee the spheroid and valve seat are closely fitted all the time when the hot stress changes. 阀座碟簧提供了连续的机械压力，保证热应力变化时球体与阀座始终密合。
- The fluctuation ball ball valve's spheroid free supporting on the valve seat, forms the one-sided seal depending on the medium pressure, therefore cannot guarantee the seal. 浮动球球阀的球体自由支承在阀座上，靠介质的压力形成单面密封，故不能保证密封。
- The upper stem is threaded into the diaphragm retainer nut. When the handwheel is rotated to the closed position the upper stem pushes on the diaphragms, which deflect downward, forcing the lower stem against the valve seat. 上阀杆通过丝口旋在横膈膜止动螺母里。当手轮旋转到关闭位置，上阀杆推动横膈膜，横膈膜下垂，迫使下阀杆接触阀座。
- Next, when a movable gate valve pin 9 is drawn out from the valve seat of a fluid conduit 15, a vacuum of the lens cavity 18 draws a liquid lens material to fill the lens cavity 18. 然后，当一个可动的门大头针9从流动的导管15的活瓣位子被画出的时候,透镜洞18的真空拉一个液体的透镜材料填充透镜洞18。
- Third, due to the structure of the three principles of eccentricity, valve plate and valve seat sealing surface is sealed between the gear on so that the torque pressure to the valve seat. 三、因三偏心结构的原理，阀板的密封面与阀座之间的密封是靠传动装置的力矩使阀板压向阀座。
- Model T8560 valve seat boring machine is suitable for repairing the valve seat of automobiles, motorcycle, tractor and other engines.It also can be used to drilling and boring etc. T8560 型气门座镗床适用于汽车、摩托车、拖拉机及其它动力机械用汽、柴油发动机的缸盖气门座圈口、气门座圈孔及导管孔的维修加工，也可用于钻孔，镗孔等加工。
