On equipped with guide's electromagnetic relief valve 9, by using guide's electromagnetic relief valve can pressure on oil circuit control so as to be capable of
Steadily export.
Equipped with liquor stream check valve 7 on described valve block, described liquor stream check valve 7 is connected with solenoid directional control valve 8, the two with
Oil circuit is connected, and solenoid directional control valve 8 can make oil circuit direction change in use, so that the piston rod on oil cylinder
Move to the direction needing, but its dwell time is shorter, in the present embodiment, will be unidirectional with liquor stream for described solenoid directional control valve 8
Valve 7 is connected, and prevents in-oil cylinder portion by using described liquor stream check valve it can be ensured that long-time pressurize to oil circuit
Part moves.
In addition, during the piston in oil cylinder drops at high speeds, because the effect of hydraulic oil and deadweight is it may appear that decrease speed
Too fast phenomenon, produces in oil cylinder and is emptied and negative pressure, and the liquor stream check valve in the present embodiment is capable of repairing, eliminates to produce and inhales
Sky or the phenomenon of negative pressure, lift control accuracy.
This utility model on described valve block equipped with filter 10, by described filter is connected with described oil cylinder,
Hydraulic oil in cyclic process can be carried out filtering cleaning it is ensured that the cleannes of fluid, prevent described guide's electromagnetic relief valve,
