Fluid control one-way scope
(1)To keep the pressure on, slide valve has a valve leakage phenomenon, only a short time packing. When packing requirements,can be added to a liquid control one-way valve in the oil, the cone valve closed tight, make oil long time pressure.chinacoal05
(2)Hydraulic cylinder "support" in the vertical cylinder, since the slide valve and pipe leaks, the piston and piston rod of gravity, may causethe piston and piston rod down. The hydraulic control one-way valve is connected to the oil hydraulic cylinder, can prevent the hydraulic cylinder piston and slide activities such as part of the decline.
(3)Hydraulic cylinder lock, when the valve is in place, the two liquid control one-way valve is closed, can be tightly closed hydraulic cylinder two chamber oil, when the piston can not move because of external force generated.
(4)Large flow of oil discharge, effective working area of hydraulic cylinder two chamber is great. When the piston back, the right cylinder chamber row oil suddenly increased, if the small flow of slide valve,throttling effect will have, restrict the speed of the piston back; if an additional liquid control one-way valve, the hydraulic cylinder piston back, the control pressure oil liquid control one-way valve is opened, it can be smoothly the right cavity fluid discharge.
(5)As the piston oil filling valve vertical hydraulic cylinder at high speed down the process, because the role of high-pressure oil and weight,resulting in decreased rapidly, resulting in air and vacuum suction,must add up oil installations. Fluid control valve used as filling oil valve, oil supplement to complete.
(6)Combined valve. In the design of hydraulic circuit, sometimes can be a liquid control one-way valve combination valve to use. For example: with two liquid control one-way valve and a check valve in parallel(one-way Fa Juzhong), equivalent to a three position three way reversing valve reversing loop. Needs to point out, the control pressure oil port does not work, should it pass back to the tank,otherwise the control piston is difficult to reset, the one-way valve can not close the reverse flow.
