valve oil can的意思|示意

However, the need for oil flow in hydraulic circuit reverse flows can use hydraulic control, opening a one-way valve, so that the flow of oil can flow in both directions.

但在液压回路中需要油流反向流动时又可利用控制油压，打开单向阀，使油流在两个方向都可流动。

The utility model can prevent the discharge-orifice steel columns of the upper draining valve cover from cracking, increase the service life of oil-well pumps, and lower oil-production cost.

本实用新型可防止抽油泵在采油过程中上排出阀罩出油孔筋柱裂断，提高抽油泵的使用寿命，降低采油成本。

This instrument can output 3v power to servo valve and is convenient for testing servo valve and oil motor at site.

本仪器可输出3 V电源给伺服阀，便于伺服阀和油动机现场调试使用。

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。

If the 450-ton valve at the wellhead can be turned on, the oil flow should stop, and the spill could be ended quickly.

如果井口450吨重的阀门可以可以关上，油流就可以停止，那么溢油很快就可以停下来。

As the valve can be replaced with pressure balance and the oil layer of the oil well can not be damaged, the oil and gas layer is better protected.

由于不用压井就能更换阀门，还不会对油井含油地层造成破坏，从而更好地保护了油气层。
