A precision regulator type direct operated relief valve

The present invention discloses a precision regulator type direct operated relief valve comprising a valve seat (1), the valve body (2), fixing screws (3), a yoke (4), permanent magnets (6), a spring ( 8), the spring seat (9), the valve body (10) and regulating screws (11), said spool (2) (1) sliding along a lumen of the valve seat, the valve body (2) of the right end surface connected to the yoke (4), a permanent magnet (6) fixed to the fixing screw (3), said fixing screw (3) and the spool (2) is connected, the regulator screw (11) and the valve body (10) , regulating screw (11) and the spring seat (9) of the right end surface of the rigid contact; a right end surface of the rigid contact of the spring seat (9) of the left end surface of the spring (8) of the spring (8) and the left end face the valve body (2) the right end surface of the rigid contact. The present invention overcomes the direct control pressure through Operated flow variations due to fluctuations caused by the oil pressure to achieve precise control.
