Embodiment
Embodiment to the utility model is described further below in conjunction with accompanying drawing.
Self-powering type sleeve adjusting valve embodiment as shown in Figure 1; Be made up of main valve and final controlling element, main valve comprises valve body 1, sleeve 2, spool 3, valve gap 4, valve rod 5, column 6, Regulation spring 7, stuffing box packing 8, Gland 9, thrust ball bearing 10, top board 11, final controlling element 12, spring seat 13, filler packing ring 14, adjustment disk 15, spacer 16 and coupling.Final controlling element adopts the piston type final controlling element, is assembled with push rod 124 by cylinder body 121, piston 122, O RunddichtringO 123.
Be provided with valve pocket in the valve body 1, the spool 3 that sleeve 2 is housed in the valve pocket and cooperates with sleeve 2.Spool 3 is fixedly connected in valve rod 5 lower ends, can in sleeve 2, move up and down, and when spool 3 seals with sleeve 2 valve pocket is divided into two chambeies up and down, and spool 3 is provided with the equalizing orifice that upper and lower cavity is communicated with, and sleeve 2 bottoms offer some circulating windows.Top board 11 is passed in valve rod 5 upper ends, connects with push rod 124 in the final controlling element 12, and valve gap 4 usefulness double-screw bolts, nut seal are fixed on the valve body 1; The column 6 that is fixed on the valve gap 4 is used for support fixation final controlling element 12, and Regulation spring 7 lower ends are contained in the adjustment disk 15, and its upper end is with spring seat 13 location; Adjustment disk 15 utilizes screw thread to be fixed on the valve gap 4; Through the position of adjustment adjustment disk 15, can change the height of Regulation spring 7, reach the effect of regulating the Regulation spring pretightening force.
Be set in the spacer 16 between valve rod 5 and valve gap 4 inner chambers, can regulate pressure according to required setting and select different thickness for use with the flow size.
Install stuffing box packing 8 in the stuffing hole of valve gap 4 additional, through compressing the sealing that Gland 9 guarantees between valve rod 5 and the valve gap 4.
Final controlling element 12 is through being bolted on the top board 11, and valve rod 4 connects with the push rod 124 of final controlling element 12.Feed liquor (gas) mouth that is communicated with the control media of regulating is offered in final controlling element 12 upper ends, and fixedly offers the relief opening that supplies to discharge gas in the cylinder body on the top board 11 of final controlling element 12.
Its working principle is: be communicated with between valve export end pressure tappings and the final controlling element feed liquor (gas) mouthful, spool is in the unlatching state of equilibrium during valve proper functioning, when the valve export end pressure raises; The pressure medium of introducing the final controlling element upper end through the pressure pipe raises; The piston promotion push rod of final controlling element is moved down, and then promote spool near the sleeve seal face, the medium circulation area reduces; Make valve export pressure reduce, tending to balance at last makes outlet pressure remain on setting value.When the valve export end pressure was elevated to certain value, spool and sleeve seal face were closed, medium runner is closed guarantee security of system.Otherwise when the valve export end pressure reduces; The final controlling element internal pressure decreases; The Regulation spring pretightening force promotes spool and moves up, and spool leaves the sleeve seal face, and the medium circulation area increases; And the rate-of flow increase makes valve export pressure raise, and tending to balance at last makes outlet pressure remain on setting value.
