The course of work:
Reversal valve upper end spool 13 is in open mode, and engine is in running order, connects by high-pressure working mediumHead is to sap cavity filling high-pressure working medium, and high-pressure working medium promotes sap cavity piston component 3 and moves downward, sap cavity piston groupPart 3 is by gas in compression air cavity, and air cavity piston component 4 is connected with screw rod 7 is fastening by connecting rod, gasThe connecting rod promotion spring base 9 of chamber piston component 4 drives main spring 8 to promote bearing 6 and moves downward, when propping upWhen seat 6 moves to push rod 12 bottom face, main spring 8 starts compression, and sap cavity piston component 3 continues fortune downwardsMoving, push rod 12 contacts with spool 13 is fastening, is greater than and changes when main spring acts on downward power on push rod 12While acting on spool 13 power upwards to valve inlet control liquid, spool 13 moves downward, reversal valve goes out,Access road is closed rapidly, and outlet is opened with floss hole, thereby it is logical to have cut off the control liquid supply of device for fillingRoad, high-pressure working medium filling operation. In said process with control gas phase connect gas cylinder in gas by compression, pressureConstantly increase, be greater than working medium and act on sap cavity piston component 3 when acting on active force on air cavity piston component 4On power time, feedway filling completes.
In the time of engine start or other system works, gas cylinder mesohigh gas push air cavity piston component 4 toUpper motion, in the time moving to as shown in Figure 1 position, screw rod 7 drives bearing 6 to compress main spring 8 bands and movesSpring abutment 9 promotes to move upward with the fastening adjustment ring being connected 10 of push rod 12, when main spring power is greater than reversal valveWhen entrance control liquid acts on power downward on spool 13, spool 13 moves upward, and reversal valve gateway is logicalRoad is opened, and valve head 14 is closed, and the high-pressure working medium service duct of device for filling is opened, device for filling starting.In the gas cylinder being connected by control gas joint 23 with upper cover in said process, gas is expanded, and pressure constantly reduces,Be less than in high-pressure working medium and act on the power on sap cavity piston 3 when acting on active force on air cavity piston component 4Time, feedway has discharged, and sap cavity piston component 3 starts to move downward, and high-pressure working medium starts filling and suppliesGive device, repeat next circulation.
Reversal valve is the final executive component of automatic reversing apparatus. In the time of valve head and valve base sealing, reversal valve goes outEntrance is opened; In the time of spool and valve base sealing, reversal valve gateway is closed, and medium is discharged from floss hole. ShouldReversal valve design feature mainly contain following some:
