When reversing valve in the median, two hydraulic controlled check valve closed, closed two cavity of the hydraulic cylinder oil, when the piston can not initiation mobile due to external utility. ( 2) 'Support' of the hydraulic cylinder. ( 6) Directional control valve. In the vertical hydraulic cylinder, because of the slide valve and tube leaking, under the gravity of the piston and piston rod, possible actuating piston and piston rod. Two cavity of the hydraulic cylinder work office plane or on the surface of the object size difference is very big. When the piston back, hydraulic cylinder cavity oil discharge quantity increases suddenly, right at this time and use small flow valve, if thought fit to initiation of throttling utility, limit the piston return rate; If adding hydraulic controlled check Industrial Valves in the hydraulic cylinder piston return, curb the open hydraulic controlled check valve, pressure oil can not meet difficulty in the cavity oil discharge right. Marine valve ( 4) Large flow discharge of oil. Vertical hydraulic cylinder of the piston in the process of high speed decreased, because of the high pressure oil, and the effect of gravity, so that decreased rapidly-changing, initiation suck air and negative pressure, be sure to add oil compensating device. ( 5) As a filling valve. Stem pressure oil oil outlet when not in office, should make it back to the fuel tank, or stem piston is difficult to reset, one-way valve can't reverse the flow. ( 3) A successful implementation hydraulic cylinder lock. Hydraulic controlled check valve as a filling valve is applied, to complete the function of fill oil. When the preset hydraulic circuits, sometimes hydraulic controlled check valve can be combined into the reversing valve is used. When the pressure requirement, can add a hydraulic controlled check valve in oil, using cone valve closed its tightness, oil pressure for a long time. To connect hydraulic controlled check valve in the hydraulic cylinder of the inferior vena oil, can avoid the hydraulic cylinder piston and slider activities such as local decline. Slide valve type directional control valve has a gap leakage phenomenon, can rapidly between the holding. For example, use two hydraulic controlled check valve and a check valve in parallel ( Check valve) of Three, the equivalent of a three-way reversing valve of commutation circuit. Q: the effect of hydraulic controlled check valve answer: ( 1) To maintain the pressure. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
