Be applied to high -efficient hydraulic means of rubbish compression

The utility model discloses a be applied to high -efficient hydraulic means of rubbish compression, including power, button switch, first drive hydrovalve, second drive hydrovalve, pressure relay and delay relay, this button switch and first drive hydrovalve are established ties the back and are connected at the both ends of power, and this second drive hydrovalve be the quick acting valve, and this delay relay detection pressure relay drives the hydrovalve with the second after continuously pressure is less than a period and the power communicates. Compared with the prior art, the system pressure must be less than the value of setting and after a period, just can switch to fast -speed second drive hydrovalve, if can filter and high -speed fall under the temporal pressure when changeing low -speed, promote whole high -efficient hydraulic means's quality.
