valve oil can

The pressure relief valve can be mounted on an oil tank cover or a lateral wall of the transformer for protection in case of pressure of the oil tank in excess of the rated valve.

它安装在变压器的油箱箱盖或侧壁上，当油箱内压力超过规定值时，对变压器起保护作用。

Two-step Breathing Valve Can Ensure the Safety of Oil Tank

两级式呼吸阀能保证油罐呼吸安全

The measuring method for valve mechanism with a direct action type hydraulic lash adjuster can be used in studying the dynamic performances of HLA, and combined with other test methods can be used to estimate the air content mixed with oil in HLA high pressure cavity.

提出的有直动式HLA的气门机构的测量方法，可用于研究HLA的动态性能，以及与其它试验方法结合推算HLA高压腔机油混气量。

Valve technology has the advantage of fast dynamic response, use of public constant pressure oil source can be controlled in different implementation of the components, but the control at loss energy, leaking, and fever are quite serious.

阀控技术的优点是动态响应快，利用公共油源可控制不同执行元件，但节流损耗较大，泄漏和发热现象比较严重。

The system real-time displays steam drum pressure, fuel oil temperature and water level, switch valve, knob and button can be operated, indicator light shows the corresponding working condition.

系统中实时显示汽包压力、锅炉燃油温度、锅炉水位的值，开关阀、按钮、旋钮都可进行操作，指示灯显示相应的工作状态。
