[0014] Figure 1 、 Figure 2 As shown in the utility model discloses a kind of early detection mechanism of hydraulic cylinder leakage of vacuum film press. As shown in Figure 1 And Figure 2 It is shown, including quick exhaust valve 1, exhaust clean valve 2.Quick exhaust valve 1 has A port, B port, C port as inlet and exhaust port;A port, C port are located at both ends of quick exhaust valve 1 respectively, B port is located at one side of quick exhaust valve 1, and close to C port.A port, C port are connected with gas source, exhaust clean valve 2 respectively, and B port is connected with the inlet and exhaust port of hydraulic cylinder 3 (see Figure 2 ).Small ball 1.1 is arranged in quick exhaust valve 1, which can move between A port and C port under the push of gas, and it is close to A port in normal state.

[0015] Its working principle is as follows:

[0016] As shown in Figure 2 When gas source gas enters from A port of quick exhaust valve 1, gas pushes small ball 1.1 to C port of quick exhaust valve 1, so as to close C port, and gas source flows into hydraulic cylinder 3 from B port, and hydraulic cylinder 3 contracts.When hydraulic cylinder 3 extends, gas in hydraulic cylinder 3 is discharged, and flows into quick exhaust valve 1 from B port, at this time, small ball 1.1 is pushed to A port of quick exhaust valve 1, so as to block A port, and gas enters exhaust clean valve 2 from C port of quick exhaust valve 1 and is discharged.If hydraulic cylinder 3 leaks, hydraulic oil will be collected by exhaust clean valve 2 with the discharge of gas.The surface of exhaust clean valve 2 is discolored after collecting oil stains, and whether the hydraulic cylinder leaks can be judged by observing the outer surface of exhaust clean valve 2.
