atos疊加式溢流閥型號，阿托斯疊加式溢流閥規格
It is generally believed that the pilot valve is the source of noise generated by the source.
When air is drawn into the oil for various reasons,
or when the oil pressure is below atmospheric pressure,
先導式溢流閥調壓失靈現象有二種情況：
一種是調節調壓手輪建立不起壓力，或壓力達不到額定數值；
另一種調節手輪壓力不下降，甚至不斷升壓。

出現調壓失靈，除閥芯因種種原因造成徑向卡緊外，還有下列一些原因
the volume suddenly smaller or bubble disappeared;
On the contrary, as in the high pressure area when the volume was small,
 and when the flow to the low pressure area, the volume suddenly increased,
Oil bubbles in the rapid changes in the phenomenon of
this phenomenon. Sudden changes in the volume of the bubble will produce noise,
這是由于溢流閥的卸荷時間很短而產生液壓沖擊所致在卸荷時，
由于油流速急劇變化，引起壓力突變，造成壓力波的沖擊。
壓力波是一個小的沖擊波，本身產生的噪聲很小，但隨油液傳到系統中，
如果同任何一個機械零件發生共振，就可能加大振動和增強噪聲。
所以在發生液壓沖擊噪聲時，一般多伴有系統振 動。
溢流閥在使用中有時會出現調壓失靈現象。
And because this process occurs in an instant,
will cause local hydraulic shock and produce vibration.
The pilot valve and the main valve port of the pilot relief valve,
the oil flow rate and pressure changes greatly,
It is prone to hole phenomenon, resulting in noise and vibration.
The part of the air dissolved in the oil will precipitate the formation of bubbles,
these bubbles in the low pressure area when the larger,
When the oil flow to the high pressure area, the compression,
