Working principle of the present invention is as follows:
Oil-feed process:
The pressure of setting ante-chamber is P1, and the pressure of lumen is P2, and the pressure of exocoel is P3, and the pressure in damping chamber is P4.
Before oil-feed, spool contacts with primary seal circle and is sealed by hydraulic fluid port II under the pressure effect of Returnning spring, and under handle is in reset mode, the termination of axis is by non-return flap jack-up.
During oil-feed, oil transport pipeline is connected on check valve body, because high liquid level (HLL) valve is in the bottom of oil tank, so need certain pressure oil body could be inputted oil tank during oil transport pipeline oil-feed, therefore the pressure of P1 is comparatively large, and the seal face that the oil body of ante-chamber is pressed in spool makes seal face compression reseting spring, and now spool is pushed open gradually by P1, spool is separated gradually with primary seal circle, and oil body enters exocoel and forms P3.Though now P1 is large, but in order to ensure the speed of oil-feed, what just need spool and primary seal circle to separate is more far away better, in order to realize this purpose, offer damping chamber as mentioned above, oil body is entered damping chamber by conduction hole part oil body and formed pressure P4 in damping chamber when entering exocoel, now P4 pressurizes to the core print seat of spool, the pressure of whole spool compression reseting spring is strengthened, make the pressure suffered by spool become P1 and P4 and, between primary seal circle and spool more away from, the generation of concussion when it also avoid valve opening like this, the speed that oil body enters oil tank becomes large, shorten the time of oil-feed.
In order to control the oil mass in oil tank, the height of ball cock device need be set in advance.During oil-feed, part oil body is entered lumen by sluice way that axis is offered and throttle orifice and is formed pressure P2, lumen is communicated with ball cock device by directintermination joint, ball cock device is arranged on the top of oil tank, in oil-feed process, ball cock device is in open mode always, and the oil body in lumen is pressed in oil tank by by ball cock device under P2 active force.When the oil body in oil tank is circulated into required amount, oil body in oil tank contacts with ball cock device and ball cock device cuts out, oil body continues to enter lumen by orifices controls the liquid of lumen is increased gradually, make spool slowly near primary seal circle, and make P2 increase to P1 value gradually, area due to spool lumen side is greater than the area of ante-chamber side, then the power that formation one is enough on spool is poor, throttle down effectively.
Spool gradually in the process of primary seal circle the P1 of ante-chamber constant, lumen controls oil-feed gradually by throttle orifice throttling, now steadily further between spool and primary seal circle, the amount that oil body enters oil tank reduces gradually, now P3 is along with reduction, slowly closing under the active force of P1, avoids the water hammer that quick closedown causes, and is conducive to the stability that high liquid level (HLL) valve cuts out.By arranging the buffer function of throttle orifice, making the power of spool both sides gradually change in closing process and closing hydraulic fluid port II.Now just complete the whole process of oil transportation.
Fuel-displaced process:
Fuel-displaced process is operated by Joystick.When draining the oil, handle is got to position of draining the oil, now handle with sleeve, handle strip movable gear shaft rotates, and gear shaft driven gear rotates, gear passes through and the teeth groove engagement be arranged on axis drives axis to slide, when opening, be against on seal face by the termination be arranged on axis, make seal face compression reseting spring by the power of handle transmission, spool and primary seal circle are separated, can drain the oil.
After draining the oil, handle is resetted, makes axis move to the position of state when hydraulic fluid port II is closed by the power of handle transmission, now by the pressure of Returnning spring, spool and primary seal circle are pushed down, seal hydraulic fluid port II, can closedown be completed.
Usually according to normal running, but when operator forget, handle is resetted, under hydraulic fluid port II is in open mode always, the operation of now above-mentioned oil-feed process controls to lose efficacy automatically, filling is emitted in order to prevent when oil-feed, at hydraulic fluid port II, place is provided with non-return flap, and non-return flap is movably connected on Boilor check valve seat by axle, and non-return flap rotates naturally by self gravitation, during oil-feed, non-return flap is pressed in hydraulic fluid port II place by oil pressure nature, prevents oil body from entering in tank, avoids causing the accident.Now just need reseting handle, reseting handle follower head jack-up non-return flap, now can by the oil-feed of above-mentioned oil-feed process safety.
Compared with prior art, traditional oiling valve and outlet valve unite two into one by the present invention, reduce cost of production, simplify tank valve technique, prevent again the generation of emitting filling, easy-to-operate simultaneously.
