阀壳

Neutral medium, it should use copper alloy shell material for the valve solenoid valve, otherwise the valve shell desquamation often rust, especially the action does not frequent occasions.

中性介质，也宜选用铜合金为阀壳材料的电磁阀，否则，阀壳中常有锈屑脱落，尤其是动作不频繁的场合。

Formed by the valve housing and valve core.

由阀壳和阀芯组成。

At one end of the valve housing are formed a pair of through-holes, which communicate with the piston operation spaces, respectively.

在阀壳的一端形成一对通孔，所述通孔分别与活塞运行空间相通。

The demolition was found, M6 wire plug off, but not in the valve housing, the last in the radiator inlet discovered.

经拆卸后发现，M6丝堵脱落，但并不在阀壳体内，最后在散热器的进油口处发现。

Gas outlet ports are formed at opposite longitudinal sides of the valve housing.

在阀壳的相对纵向侧面形成出气孔。

The temperature and stress in valve housing of medium cylinder in super critical steam turbine during cold start and under nominal load were calculated with FEM cord NASTRAN.

采用大型有限元分析软件NASTRAN，对超临界1000 MW汽轮机中压缸主汽阀阀壳的冷态启动过程和额定工况下的温度场和应力场进行计算，得到了冷启动过程中阀壳的温度和应力分布规律，并将冷启动结束时的计算结果同额定工况下的计算结果作一对比分析。

Based on the FEM,the calculation and analysis were performed for the transient temperature field s and stress fields of the intermediate pressure main steam valve housing under various operating conditions including cold startup,shutdown,strong hot startup,limit hot startup and accidental condition in 200MW unit in power station.

采用有限元方法，计算分析了电站200MW汽轮机中压主汽阀阀壳在冷启、停机、强热启动、极热启动以及事故等工况下的温度场和应力场，得出了阀壳裂纹区各工况下温度场和应力场的变化规律，提出了内壁裂纹区的周向应力是疲劳寿命计算的主要参考量。

The dual-piston valve comprises a valve housing having a pair of piston operation spaces defined therein and a pair of pistons disposed in the piston operation spaces of the valve housing such that the pistons can be vertically moved to open or close inner and outer outlet ports formed at a cylinder.

该双活塞阀包括：阀壳，其中限定有一对活塞运行空间；以及一对活塞，其设置在阀壳的活塞运行空间中，以使活塞能垂直移动以打开或关闭在气缸处形成的内出口和外出口。

A shear groove in the external casing or other appropriate means so arranged that should the valve casing be removed by a severe impact the sealing capability of the valve closure shall not be affected.

e阀外壳应有削弱部分，当在强烈撞击下阀壳被折断时，内部截至阀应保持有效关闭。同时，阀门的操作机构不能直接连接阀板。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
