Working principle:
according to specific use modes, the utility model is divided into three working modes of automatic air supplementing, manual air supplementing and overhauling and exhausting, wherein a pressure oil tank is connected with an interface 10 of a working cavity A.
First, automatic air supply and stop: the manual ball valve 5 is always closed in this process.
When the automatic air supplementing condition is met (generally judged and controlled by a PLC program), the second electric ball valve 3 is automatically closed, the first electric ball valve 2 is automatically opened, high-pressure air enters from the pressure air source P interface 7 and then sequentially passes through the filter 1, the first electric ball valve 2 and the one-way valve 4 and reaches the pressure oil tank, so that air supplementing is realized.
When the condition of stopping air supply is met, the first electric ball valve 2 is automatically closed, and air supply is stopped; opening a second electric ball valve 3, and blocking the air pressure of the oil pressing tank by a one-way valve 4; the gas in the pipeline between the first electric ball valve 2 and the one-way valve 4 is emptied to normal pressure through the second electric ball valve 3, and the sealing of the one-way valve 4 is further enhanced.
Second, manual air make-up and stop: the manual ball valve 5 is closed.
The second electric ball valve 3 is closed and the first electric ball valve 2 is opened through a manual knob of the electric ball valve, so that manual air supplementing is realized, high-pressure air enters from the pressure air source P interface 7 and then sequentially passes through the filter 1, the first electric ball valve 2 and the one-way valve 4 and reaches the pressure oil tank, and air supplementing is realized.
When the pressure oil tank is full of air, the first electric ball valve 2 is closed through a manual knob of the first electric ball valve 2, and air supplementing is stopped; opening the second electric ball valve 3 through a manual knob of the second electric ball valve 3, wherein the air pressure of the oil pressing tank is blocked by the one-way valve 4; the gas in the pipeline between the first electric ball valve 2 and the one-way valve 4 is emptied to normal pressure through the second electric ball valve 3, and the sealing of the one-way valve 4 is further enhanced.
Third, overhaul exhaust.
When the high-pressure gas is required to be discharged during maintenance, the control power supply is turned off, and the manual ball valve 5 is pulled to the exhaust position for exhaust.
It should be noted that, when the air is supplied and exhausted manually, the power supply must be turned off.
