Fluid control one-way pneumatic valve in use should be paid attention to what?

want to understand hydraulic control one-way pneumatic valve use matters needing attention, first of all follow the big blue under the hydraulic pressure to get to know the working principle of hydraulic control one-way pneumatic valve.
and the definition of hydraulic control one-way pneumatic valve, pneumatic valve hydraulic control one-way depend on control fluid pressure, can make the one-way pneumatic valve pneumatic valve reverse circulation.
and the working principle of hydraulic control one-way pneumatic valve:
(1) when the control oil did not turn on the pressure oil, hydraulic control one-way pneumatic valve work like ordinary one-way pneumatic valve, pressure oil from the oil inlet flow to the oil outlet only, can't reverse flow.
2. When the control oil pressure control input, plunger piston under the action of pressure oil to the right, with a plunger drive one-way pneumatic valve, make the oil in and out of the mouth. If the oil outlet is greater than the oil inlet can make the oil flow.
and hydraulic control one-way pneumatic valve use notice:
(1) must ensure that have enough control hydraulic control one-way pneumatic valve pressure, absolutely not allowed to control the pressure loss of pressure.
2) should be paid attention to control the pressure whether meet the requirements of reverse open.
3. If the hydraulic control one-way pneumatic valve control system for autonomous, to analysis the change of the main system pressure influence on control oil pressure, lest appear the false operation of hydraulic control one-way pneumatic valve.
(4) according to the hydraulic control one-way pneumatic valve in hydraulic system of position or reverse after oil cavity flow resistance ( Back pressure) Size, selection of hydraulic control one-way pneumatic valve structure ( Short form or double entry) And drainage method ( Inside leaking or leakage) 。
(5) for internal drainage hydraulic control one-way pneumatic valve, when the reverse oil outlet pressure exceeds a certain value, the hydraulic control part will be out of control, so the inside leaking type hydraulic control one-way pneumatic valve is commonly used in reverse without back pressure or back pressure of the oil cavity smaller occasions;
6 and leaked type hydraulic control one-way pneumatic valve can be used to reverse the occasion of high back pressure of the oil cavity, in order to reduce the minimum pressure of control, power saving control. Within the system if the dump, the plunger cylinder will be issued intermittent fall in vibration and noise.
