Embodiment
The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-3, are explained through following mode of execution.
Like accompanying drawing 1-3; The heavy caliber sleeve piston type of the utility model modulating valve that surges; Be made up of modulating valve and hydraulic servomechanism, wherein modulating valve is made up of front valve shell 1, rear valve body 2, sleeve 4, spool 3, valve rod 11, guide rod 5, cowling 6, rocking arm 1 and connecting rod 8; Hydraulic actuator 10 connects rocking arm 2 12, and both are located at modulating valve valve body top, and rocking arm 2 12 is connected with the top of valve rod 11; Sleeve 4 is located in the front valve shell 1 with spool 3 levels, has throttling window 7 on the circumference of sleeve 4 near front valve shell 1 end, and spool 3 bottoms connect rocking arm 1 through connecting rod 8, and rocking arm 1 was connected with the end of valve rod 11; Two horizontally-guided bars are located in the sleeve 4, and spool 3 is slidingly matched with guide rod; The circular base of hemispherical cowling 6 and the tail end of sleeve 4 join, and the top of cowling 6 is positioned at rear valve body 2.
The heavy caliber sleeve piston type of the utility model modulating valve that surges, wherein said spool 3 is provided with sealing pair with valve base chamber, and sealing pair can be fully hard sealing, also can be the soft or hard double seal.
The utility model adopts the sleeve balance type structure.Flow in the air-flow path of fluid looping between sleeve and front valve shell inner chamber, between cowling and the rear valve body inner chamber, the open and close of modulating valve are realized by the to-and-fro motion that is placed on the outer hydraulic actuator of front valve shell.
When the needs Open valve; Send out the valve current signal by the control room to the electrohydraulic control that is installed on the oil cylinder, high pressure oil gets into oil cylinder one side, and the piston motion in the oil cylinder also drives external rocking arm at front valve shell and makes the valve rod rotation; Rocking arm in the modulating valve front valve shell rotates with valve rod; And drive spool through the linkage mechanism in the front valve shell and move right along guide rod, on sleeve, have the throttling window that satisfies Flow characteristics, along with spool moves right; Opening area on the sleeve is increased gradually, and the throttling window that air-flow is flowed through from the annular pass between front valve shell and the sleeve on the sleeve again flows out.Opening degree through the control spool changes the area of throttling window on the sleeve, to realize the adjusting to flow behind the valve.When needs were all opened valve, when opening fast the end, the inner pooling feature of oil cylinder played a role, and makes the spool easy motion to fully open position.Avoid producing and impact.
When the needs throttle down, send the pass valve signal by the control room to the electrohydraulic control that is installed on the oil cylinder, high pressure oil gets into the oil cylinder opposite side; Piston motion in the oil cylinder also drives external rocking arm at front case and makes valve rod rotation; Rocking arm in the modulating valve front valve shell rotates with valve rod, and is moved to the left along guide rod through the drive of the linkage mechanism in front valve shell spool, and the opening area on the sleeve is reduced gradually; At spool during soon near valve seat; The inner pooling feature of oil cylinder plays a role, and makes spool steadily press to valve seat, thus the final plant closure modulating valve.Realize sealing and provide continuing the power of closing, keep sealing reliable by oil cylinder.
