The present invention is achieved in the following manner: multi-functional ball cock for supplementing or discharging oil mainly is made up of main members such as valve body 1, spool 2, connecting rod rest 3, connecting rod 4, ball float 5, oil extraction conduit 6, non-return flaps 7, when this valve was between repairing and the oil extraction position, the center of valve body 1, spool 2, connecting rod rest 3, connecting rod 4, ball float 5 was that same horizontal line connects; Valve body 1 and spool 2 cooperates and constitutes rotary valves, and the end face of valve body 1 and communicates with the repairing passage and the oil drain passage of valve inner respectively except that being provided with the repairing pipe 8 that is connected with exterior line, oil exit pipe 9, also be provided with power oil exit pipe 10; Drive spools through connecting rod 4, connecting rod rest 3 when ball float 5 moves up and down and do clockwise or rotate counterclockwise, the opening or disconnect of control repairing or oil drain passage.Repairing channel part wherein: the repairing pipe 8 on the valve body 1 is communicated with first circular groove 12 of spools 2 one ends through the second repairing hole 18,13 are communicated with spool center hole 11 through the hole, the first repairing hole 14 as control gate connects center hole 11, and match with the 3rd repairing hole 19 on being located at valve body, spool 2 is done downwards by the center the first repairing hole 14 and repairing hole 19 are connected, otherwise then disconnect, constitute the repairing control system; In the oil drain passage part: the oil exit pipe 9 on the valve body 1 communicates with first oil drainage hole 20 on valve body top, the bottom of same cross section symmetry spool is provided with second oil drainage hole 21 and is communicated with the 3rd oil drainage hole 22, the 3rd oil drainage hole 22 lower ends are provided with non-return flap 7 successively, oil extraction skirt 6, wherein non-return flap 7 is vertically installed, steel ball 23 is pressed on the gate seat hole, same cross section spool 2 is provided with the semi-circular groove 15 of oil extraction along circumferential surface, match with first oil drainage hole 20 in the upper end of the semi-circular groove 15 of oil extraction, the lower end is communicated with second oil drainage hole 21, spool 2 is upwards done by the center oil drainage hole 20 and oil drainage hole 21 are connected, otherwise then disconnects, and constitutes oil draining system; The side of the 3rd oil drainage hole 22 also communicates with power oil exit pipe 10, and match with oil drain passage form power oil extraction automatic control system valve body, (power oil exit pipe 10 communicates with the 3rd oil drainage hole 22, second oil drainage hole 21 successively as shown in Figure 1, and semi-circular groove 15 controls of the oil extraction on spool 2, be communicated with or disconnect first oil drainage hole 20, the oil exit pipe 9 on valve body top, constitute the power oil drain passage as shown in Figure 6).
Working principle of the present invention is: at first this valve is installed in leakproof fuel cell one side central position, wherein repairing pipe 8 is connected with empty side oil supply system oil pump outlet; Oil exit pipe 9 joins with the oil sources main fuel tank of empty side system; Power oil exit pipe 10 is connected by valve with the outlet of hydrogen side oil supply system oil pump.After putting into operation at first the pressure oil from empty side oil supply system on first circular groove 12 of valve body repairing pipe 8, form a high pressure oil ring (as accompanying drawing 3 at spool 2, shown in 4) and enter center hole 11 by hole 13, form another high pressure oil ring (as accompanying drawing 3 through aperture 17 at second circular groove 16 again, shown in 7), two oil rings play good seal action at the spool two ends, its effect is to prevent that the hydrogen of liquid upper in leakproof fuel cell process spool and valve body gap from entering valve inner and discharging by oil drainage hole, this is that this valve can be installed in one of condition that the fuel tank intermediate portion should possess, and also is one of this valve feature; When liquid level is in the fuel tank neutral position,,, be in the state of not arranging of not mending this moment so repairing hole 19 on the valve body 1 and oil drainage hole 20 are blocked (shown in Fig. 5,6) by spool 2 because the center of ball float 5, connecting rod 4, connecting rod rest 3 and valve body 1 is same horizontal plane.Can accomplish that ball float 5, connecting rod 4, connecting rod rest 3 are same horizontal plane with the center of valve body 1, be because in oil draining system, be provided with oil extraction conduit 6, even oil drainage hole can not expose liquid level yet when so just having guaranteed that the oil level of fuel tank is very low, avoid hydrogen to overflow from oil drainage hole, and needn't resemble ball float need be arranged on the pressure-stabilizing ball cock for supplementing or discharging oil be higher than a safe distance of valve body height, this also is one of this valve feature; When fuel tank liquid level descends, ball float 5 descends thereupon and by connecting rod spool 2 is done turn clockwise (as shown in Figure 5) along the direction of arrow, when the 3rd repairing hole 19 is connected on first repairing hole 14 on the spool 2 and the valve body, from the pressure oil of empty side system repairing pipe 8 on valve body successively, the second repairing hole 18, first circular groove 12 on the spool, hole 13, center spool hole 11, the first repairing hole 14,19 pairs of leakproof fuel cells in the 3rd repairing hole on the valve body carry out repairing, the big more repairing amount of the low more spool angle of swing of liquid level is also big more, when repairing amount and fuel level in tank loss amount reach balance, level height is controlled no longer to change, the flow of repairing also no longer changes, because adopted the first repairing hole 14 that connects center hole 11 as the control gate of controlling the repairing passage, do not produce the power that makes spool push a side to so can not resemble the pressure-stabilizing ball cock for supplementing or discharging oil, ball float is free to move up and down with liquid level, control repairing door aperture very stably, no creeping phenomenon, so this valve can not cause the pressure fluctuation of sky side oil supply system to the leakproof fuel cell repairing time, this point is extremely important to the safe operation of unit, and this also is one of feature of the present invention; Because this feature also just needn't be provided with voltage stabilizing mechanism in addition, similar pressure-stabilizing ball cock for supplementing or discharging oil can not take place simultaneously yet take place because of the stuck accident of the too high appearance of oil compensation pressure.When liquid level raises because of certain reason, ball float 5 rises thereupon and makes spool be rotated counterclockwise (as shown in Figure 6) along the direction of arrow by connecting rod, the external valve of power oil exit pipe 10 is in closed condition when normally moving because of unit, so when first oil drainage hole 20 is connected by the semi-circular groove 15 of spool 2, under the effect of portion's Hydrogen Vapor Pressure within it of the liquid of leakproof fuel cell through oil extraction conduit 6, non-return flap 7, the 3rd oil drainage hole 22, second oil drainage hole 21, the semi-circular groove 15 of spool, first oil drainage hole 20, oil exit pipe 9 enters the oil sources main fuel tank of sky side system, here need to prove because the pressure of oil extraction relatively supports, so the thrust that produces on the semi-circular groove 15 of oil extraction can be ignored.If the Hydrogen Vapor Pressure in the leakproof fuel cell is low excessively, perhaps when generator carries out gas displacement and vacuumizes, the oil in the leakproof fuel cell can't be discharged, and can open the external valve of valve body power oil exit pipe 10 this moment, promptly is convertible into the power oil extraction and controls automatically.Working principle is: when fuel level in tank raises, when first oil drainage hole 20 is connected with the semi-circular groove 15 of oil extraction, pressure oil (inlet of this pump is connected to leakproof fuel cell) from the outlet of hydrogen side oil pump is discharged through valve body power oil exit pipe 10, the 3rd oil drainage hole 22, second oil drainage hole 21, the semi-circular groove 15 of oil extraction, first oil drainage hole 20, oil exit pipe 9, the steel ball 23 of non-return flap is being pressed under the oil pressure effect on the non-return flap seat, so should can not return leakproof fuel cell by oil, thereby the oil extraction of realization power is controlled automatically, and this also is a key character of the present invention.
The present invention compares with original technology has following advantage: 1, increased the power automatic oil draining, function is more comprehensive; This valve is realized by zero hydrogen pressure to specified hydrogen pressure whole-process automatic control; 2, owing to the semi-circular groove of former repairing on the spool changes through hole 14 into, the oil compensation pressure height does not influence the action of spool like this, the creeping phenomenon in spool stuck and when control when having avoided empty side oil supply system oil pressure too high, made things convenient for simultaneously maintenance again, because with connecting rod rest when spool takes off, spool does not influence usability for 180 ° along the axis rotary spool, setup error when avoiding overhauling; 3, former floating ball rod be bent upwards change into straight-bar be float valve be in do not mend valve body, spool, connecting rod, ball float when not arranging intermediateness the center on a horizontal plane, when having avoided ball float to rise to peak, because of the too little phenomenon that can't fall after rise of moment with liquid level; 4, having designed non-return flap 7 is independent of each other leakproof fuel cell nature oil extraction and power oil extraction; 5, more increased the safety of operation behind the increase oil extraction skirt 6, avoided being stuck in the oil extraction position and liquid level is reduced to valve body when following when spool, hydrogen is discharged from oil drainage hole and is caused serious accident, because the lower end of oil extraction skirt is lower than liquid level lower limit alert locations, that is to say that this pipe is embedded in the oil all the time.
Operation proof the present invention through many units such as Guangdong Sha Jiao power plant, Shijingshan, Beijing, mother gulf, Shenzhen power plant has simple in structure, reliable, the oil level precise control, and realize unit by the whole-process automatic control of zero hydrogen pressure to specified hydrogen pressure, every technical order all meets design idea.
