The present invention compared with prior art, with following beneficial effect：
1st, the present invention be directed to a hydraulic control valve of hydro cone-crusher design, the difference of disintegrating machine is being detected
Running status when, corresponding treatment action can be more quickly made to protect the normal operation of disintegrating machine, reduce difficulty and mince
Deng the infringement to disintegrating machine, increase disintegrating machine service life.
2nd, because gyratory crusher is an equipment for high loaded process, its hydraulic control system must be stablized, the present invention
Hydraulic control valve has simple structure, and the advantage of good stability can realize direction in gyratory crusher operation process is controlled
Control, pressure protection and hydraulic fluid flow rate control.
3rd, hydraulic control valve of the present invention devises a manual start device, for being used under the state of emergency.For example in oil
Dirt plugs valve.Manually operated step is as follows：Screwed cap is unclamped first, pin is pushed, if this can not be complete with hand
Into, a bead or other suitable things please be put into screwed cap, to tighten inward, such pin can push-in, startup
Hydraulic oil pump, the then oil crushed in Oil cylinder is extracted.
4th, hydraulic control valve of the present invention combines check valve and pressure limiting valve, reduces the company between conventional valve and valve
Connect, that is, reduce leakage, and total quality and size are smaller, have saved cost, it is easy to maintenance.
From the foregoing, it will be observed that simple structure of the present invention, stablizes, direction controlling, pressure protection and hydraulic fluid flow rate control are realized
System, can protect hydraulic pump and gyratory crusher.
