REXROTH閥08.45.86-X-Y-Z選型及介紹
Description
When pressure at V2 rises above the spring bias pressure, the check seat is pushed away from the piston and flow is allowed from V2 to C2. When load pressure at C2 rises above the pressure setting, the direct-acting, differential area, relief function is activated and flow is relieved from C2 to V2. With pilot pressure at V1–C1 , the pressure setting is reduced in proportion to the stated ratio of the valve, until opening and allowing flow from C2 to V2. The spring chamber is vented to atmosphere allowing operation of all functions independent of back-pressure at V2.
Note: port identified with M are not protected with calibrated orifice but in direct connection with pressure channels.
描述
當V2處的壓力上升到高于彈簧偏置壓力時，止回閥座被推離活塞，并允許從V2到C2的流量。當C2處的負載壓力升至壓力設定值以上時，將激活直接作用的差動面積，溢流功能，并且流量將從C2釋放至V2。在先導壓力為V1-C1的情況下，壓力設定將按閥的規(guī)定比例成比例降低，直到打開并允許從C2到V2的流量為止。彈簧腔與大氣相通，可獨立于V2的背壓執(zhí)行所有功能。
注意：標記為M的端口沒有經(jīng)過校準的節(jié)流孔保護，而是與壓力通道直接連接。
