Pneumatic valve mechanical tips: how to make the liquid in the best working state

oil and gas dynamic filling valve: use on the medium and large hydraulic press. Intent is to increase oil, lower the master cylinder speed. Device in between the master cylinder and tank. Fall, its operation principle: master cylinder piston, piston due to the weight is reduced, the master cylinder cavity into the vacuum condition, the oil and gas filling valve of pneumatic valve mouth open, put on the fuel tank of oil in the cavity on the cylinder. After putting in place the piston, spring to oil and gas charging valve closed, press in the oil pump oil supply work under pressure. And then to supply oil to the main cylinder inferior vena kickback piston pump, when the piston has yet to move, inferior vena have pressure, small tube of the pneumatic valve and turn over oil and gas filling valve, piston rises, oil tank on the back. After the tank is full, there is a big pipe to much back in the tank.
liquid pneumatic valve is used between hydraulic cylinder and tank discharge of oil absorption use pneumatic valve, pneumatic valve liquid to ride fast of large press, from the cylinder to the fuel tank of oil absorption, pressure from the cylinder into the fuel tank, avoid when reverse from the cylinder when the discharge of oil into the tank. Flange type pneumatic valve body liquid volume is small, with large flow and no leakage, can be directly welded or flanged fixed maximum flow is comfortable activity when the pressure loss when the value of income. Minimum hydraulic control pressure ratio for some pneumatic seat with hydraulic control compression some area than the resolution. On the way back, must first pressure, otherwise can't open or form. It controls oil cylinder was forced to, control oil pressure oil, liquid pneumatic valve open, oil cylinder filling liquid for vacuum pneumatic valve cavity derive a lot of oil, when demand was pressurized marched on, manipulation of the pressure oil disconnect, liquid pneumatic valve closed, pneumatic valve cavity type high pressure oil cylinder filling liquid slow travel. Return, liquid pneumatic valve open again, the oil after charging pneumatic valve hurtling back to tank.
pneumatic valve in tons of liquid, the press, the cylinder is bigger, light oil, descending speed too slow, so, on top of the compressor set up on a tank, between the tank and oil cylinder cavity on device charging pneumatic valve. When the piston to reduce liquid pneumatic valve open, fuel tank of oil directly on the oil cylinder cavity. Pressure, by oil pump pressure. Piston rises, liquid pneumatic valve open, oil cylinder oil cavity on returning to the tank. I can't figure here, can't give you see schematic diagram. Traditional liquid SLG - pneumatic valve Usually used as between the discharge of oil absorption of pneumatic valve, fast to process of large press, from the oil cylinder tank of oil absorption, avoid when pressurized cylinder into the fuel tank, reverse from the cylinder to the tank. Traditional liquid SLG - pneumatic valve Processing is exquisite, the precision is high, the pressure maintaining outstanding function. Pneumatic valve with traditional liquid buffer pneumatic valve core, can be useful to cut impact and oscillation. Traditional liquid SLG - pneumatic valve Widely used in high-speed punching machine, pressing machine, injection machine and machine.
