Accompanying drawing explanation
Fig. 1 is the structural representation that one embodiment of the invention fills valve.
Fig. 2 is the fundamental diagram that one embodiment of the invention fills valve.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
As shown in Figure 1, Fig. 1 shows the structural representation of one embodiment of the invention.The sealed characteristic that the present embodiment fills valve is 300 DEG C, static seal under 200MPa superhigh-pressure high-temp operating mode, can select combination seal to realize.Wherein, when system is in low-pressure, the O-ring seals of resistance to 300 DEG C of temperature is selected to seal; When system is in hyperpressure, self-energized seal principle is adopted to realize superhigh pressure sealing requirement.Fill valve mounting interface 1 in the present embodiment, be the mounting interface filling valve and super-pressure working cylinder, fill valve and be connected with super-pressure working cylinder by the screw thread on valve body 8.The valve port filling valve valve body is provided with spool 2, and spool 2 is cone structures.As preferred embodiment, in the present embodiment, spool 2 is provided with the first seal ring 3; Preferably, in the present embodiment, the first seal ring 3 is the nonmetal O-ring seals of exotic material.The spool 2 filling valve forms the sealing to filling valve endoporus together with the first seal ring 3.Embodiment is: when clutch release slave cylinder is in low-pressure state, nonmetal first seal ring plays seal action, as the pressure increases, first seal ring can not meet the seal request to ultrahigh pressure, at this moment, under hyperpressure effect, the male cone (strobilus masculinus) of spool 2 and the inner conical surface of valve seat 7 are close to mutually, realize the sealing to ultrahigh pressure.The present embodiment fills valve and also comprises valve seat 7, valve seat 7 outer wall forward position is provided with the second seal ring 4; Valve seat 7 external rear wall position is provided with the 3rd seal ring 5; The 4th seal ring 6 is provided with bottom valve seat 7; As preferred embodiment, in the present embodiment, the second seal ring 4 is the nonmetal seal ring of exotic material, 3rd seal ring 5 is triangle metal seal ring, the second seal ring 4, the 3rd seal ring 5 and valve seat 7, and three's composition installs the sealing of endoporus to filling valve.As preferred embodiment, the second seal ring 4 is O-ring seals.Specific embodiments is: when clutch release slave cylinder is in low-pressure state, nonmetal second seal ring 4 plays seal action, as the pressure increases, the both sides of the 3rd seal ring 5 are pressed in the male cone (strobilus masculinus) of valve seat 7 and fill the inner hole surface of valve mounting interface 1 by ultra high pressure oil respectively, realize the sealing to ultrahigh pressure.Fill valve valve body 8 in the present embodiment, function is compression, fixed valve base 7, and realizes the circulation of low-pressure medium oil.Valve body 8 is provided with low pressure oil way interface 10.The present embodiment fills valve and also comprises driving cylinder 11, is provided with air cylinder tie rod 9 in valve body 8, and air cylinder tie rod 9 is connected with driving cylinder 11.As preferred embodiment, drive cylinder piston in cylinder with magnet ring in the present embodiment, the magnetic induction sensor be arranged on cylinder connecting rod can detect piston position, thus judges that filling valve is in unlatching or closed condition.When air cylinder tie rod 9 is to left movement, fill valve and open, Medium Oil is through low pressure oil way interface 10 pairs of super-pressure working cylinder topping ups and discharge opeing; When air cylinder tie rod 9 moves right, fill valve and close, realize superhigh pressure sealing.In the present embodiment, the first seal ring 3, second seal ring 4 and the 4th seal ring 6 are all non-metal o-rings, and make for special nonmetallic material, can tolerate the high temperature of the highest 315 DEG C.
As shown in Figure 2, Fig. 2 shows the fundamental diagram that the present embodiment fills valve.The valve port 21 filling valve is connected with super-pressure working cylinder 23, fills valve is provided with low pressure fills discharge pipe 24; Valve port 21 lower end filling valve is connected with and drives cylinder 22.When driving cylinder J place to connect source of the gas, filling valve and opening, topping up or discharge opeing are carried out to super-pressure working cylinder; When driving cylinder I place to connect source of the gas, filling valve and closing, realizing the sealing to filling oil extraction road.The workflow that the present embodiment fills valve is: drive the air inlet of cylinder side, promotes spool to left movement, opens and fill valve, at this moment, fill valve and be in opening state, both can realize carrying out oil-filled to clutch release slave cylinder, also can realize carrying out oil extraction to clutch release slave cylinder; When driving cylinder opposite side air inlet, pulling spool to move right, closing and filling valve, at this moment fill the sealing function that valve spool and valve seat realize filling valve.
