Coil power, the electromagnetic suction is zero, the Deputy valve valve plug and the dynamic role of the iron core because of spring brought up, the Deputy valve is opened, the main valve on the valve cup of fluid flow out through the SAFETY VALVES Vice-valve, reducing the role of the cup on the valve in the main valve pressure, when the main valve to reduce pressure on the valve cup to a certain value, the use of pressure to push the main valve valve cup, the solenoid valve is opened, media circulation.

线圈断电时，电磁吸力为零，副阀阀塞和动铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，利用压差把主阀阀杯推起，电磁阀打开，介质流通。& 2 two-pass solenoid valve works &是由中国针型阀网提供的国际阀门新闻，译文仅供参考。另外，中国针型阀网还提供相关产品搜索：针型阀型号、针型阀价格、针型阀技术、针型阀新闻、针型阀生产商等。

热力膨帐阀的过热度由开启过热度和有效过热度组成，开启过热度与弹簧的预紧力有关，有效过热度与弹簧的强度及阀针的行程有关。

Objective To evaluate the diagnostic accuracy in terms of surface location, the needle, sampling method and the character of lesion. To investigate the complication of CT-guided percutaneous pulmonary biopsy with spring core biopsy needle.

目的 评价CT导引下应用弹簧芯状活检针经皮肺穿刺活检术中CT定位方法、穿刺针的选择、组织取材方法、病变特点等因素对本项检查诊断准确性的影响，探讨CT导引下应用弹簧芯状活检针肺穿刺活检术并发症的发生率、影响因素以及防治措施。

By adopting mechanical driving mode, the machine can be used for perform injection with stable pressure on bone pork, beef and poultry. When the injection needle contacts the bone, the downward movement is stopped by the pneumatic spring to protect the needle. The air chamber pressure of pneumatic spring is adjustable in order to ensure no damage on the bone.

用途采用机械驱动方式可对猪肉、牛肉及禽肉等带骨肉以稳定的压力注射，注射针在遇到骨头等硬物后可自动在气弹簧的作用下停止向下运行，保护注射针，气弹簧的气室压力可调节，保证对原料中骨结构不破坏。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
