The invention discloses a hydraulic system and a throttle valve. The throttle valve comprises a valve body, an adjusting screw in the valve body cavity and a tapered valve at the front end of the adjusting screw. An oil inlet and an oil outlet are formed in the valve body and are communicated through a throttle opening. An axial hole communicated with the oil inlet is formed in the front end of the adjusting screw, and throttle holes communicated with the axial hole is formed in the peripheral wall. The tapered valve can move axially to open and close the throttle opening. The tapered valve and the front end can move axially mutually to close to open throttle holes. The throttle valve is good in throttle adjusting stability and reliability and long in service life.
