Abstract
The utility model relates to a manual controller of a hydraulic valve used for remotely controlling the manually inverting of the hydraulic valve. The controller comprises a connecting tube 2, a draught rod 3, a cam 7, a cam box 4, a rotating shaft 8, a rotating handle 10 and a fixed handle 9. The draught rod is inserted in the connecting tube; the cam is positioned in the cam box and arranged on one end of the rotating shaft; the other end of the rotating shaft is fixed and connected with the rotating handle which is rotatablely arranged on the fixed handle; the fixed handle is fixed and connected with the cam box. The utility model is characterized in that the outer end face of the cam is provided with a curve groove 6 from the interior to the exterior; one end of the draught rod is fixed with a pin shaft 5 which is positioned in the groove. The utility model is not only applicable to the manual controller of the two-position valve, but also suitable for the manual controller of the two-position valve, thereby having wide application scope.
Description
Technical field:
The utility model relates to a kind of hydrovalve manual overvide.The manual reverse of direction that is used for the distant control hydrovalve.Belong to the control block hydraulic unit with technical field.
Background technique:
The remote manual overvide of existing hydrovalve such as Fig. 1,2 generally are made up of connecting tube, draw-bar, cam, cam box, rotating shaft, bearing, rotary handle and integral cast handle etc.Draw-bar is inserted in the connecting tube, and an end links to each other with spool, and the other end links to each other with cam, and cam places in the cam box, and cam gear is in rotating shaft one end, and the rotating shaft the other end links to each other with rotary handle, and bearing means is at rotating shaft two ends, and integral cast handle is fixedlyed connected with cam box.Rotate rotary handle, drive the cam rotation, travel forward, the folding (Fig. 3) of control spool thereby promote draw-bar.Lean on the spring reset of hydrovalve inside when resetting.Its shortcoming is: it can only promote spool and move to a direction, relatively is suitable for the control of a direction of two-position valve.And need two direction motions promptly inapplicable for three-position valve.Therefore Applicable scope is narrower.
Summary of the invention:
The purpose of this utility model is to provide a kind of two-position valve that can be applicable to can be applicable to the novel hydraulic valve manual overvide of three-position valve again.
Technology contents of the present utility model is:
A kind of novel hydraulic valve manual overvide, comprise connecting tube, draw-bar, cam, cam box, rotating shaft, rotary handle and integral cast handle, draw-bar is inserted in the connecting tube, cam places in the cam box, be installed on rotating shaft one end, the rotating shaft the other end is fixedlyed connected with rotary handle, the rotary handle spinning is on integral cast handle, integral cast handle is fixedlyed connected with cam box, be characterized in offering from the inside to the outside on the cam exterior edge face curved slot, draw-bar one end is fixed a bearing pin, and bearing pin places in the groove.
Described curved slot by interior, in, outer three sections be formed by connecting, an inner segment AB and an outer section CD are the involute groove, intermediate section BC is an arc groove.
Rotate rotary handle to a direction, drive the cam rotation, bearing pin is moved to the A point by the B point in groove AB section, thereby moves to a direction by draw-bar pulling hydrovalve spool, returns to BC section (arc section) when resetting; Otherwise bearing pin is moved to the D point by the C point in groove CD section, and the hydrovalve spool moves to other direction, realizes the purpose of commutation.Therefore, the utility model both had been applicable to the control of a direction motion of two-position valve, was applicable to that again three-position valve needs the control of two direction motions, and Applicable scope is wider.

Fig. 1 is the structural representation of existing cam
Fig. 2 is the A-A cut-away view of Fig. 1
Fig. 3 is the schematic diagram with two hydrovalves of existing control gear control.
Fig. 4 is an example structure schematic representation of the present utility model
Fig. 5 is a cam structure schematic representation of the present utility model.
Fig. 6 is the B-B cut-away view of Fig. 5
Fig. 7 is the schematic diagram with three hydrovalves of the utility model control.
Embodiment:
Fig. 4 is an example structure schematic representation of the present utility model.Its left side hydrovalve is a two-position valve, and cam is common cam, adopts existing control gear control.The right-hand part hydrovalve is a three-position valve, and cam is a curve cam, adopts the utility model control.The right-hand part control gear mainly is made up of connecting tube 2, draw-bar 3, bearing pin 5, cam 7, cam box 4, rotating shaft 8, bearing 11, rotary handle 10 and integral cast handle 9 etc.Draw-bar 3 is inserted in the connecting tube 2, the one end links to each other with hydrovalve spool 1, the other end fixed pin shaft 5, cam 7 places in the cam box 4, be installed on rotating shaft 8 one ends, rotating shaft 8 the other ends are fixedlyed connected with rotary handle 10, and rotary handle 10 spinnings are on integral cast handle 9, integral cast handle 9 is fixedlyed connected with cam box 4, and bearing 11 devices are at rotating shaft 8 two ends.
As Fig. 5, offer curved slot 6 from the inside to the outside on cam 7 outside end faces, bearing pin 5 places in the curved slot 6.Groove 6 by interior, in, outer three sections AB, BC, CD are formed by connecting, an inner segment AB and an outer section CD are the involute groove, intermediate section BC is an arc groove.
Clockwise rotate rotary handle, the rotation of drive cam, bearing pin is moved to the A point by the B point in groove AB section, thereby the pulling draw-bar moves right, driving the hydrovalve spool moves to the right, pressure oil enters chamber, an oil hydraulic cylinder left side, and hydraulic cylinder piston rod stretches out (Fig. 6), returns to BC section (arc section) by the spring in the hydrovalve when resetting; Rotate counterclockwise rotary handle, bearing pin is moved to the D point by the C point in groove CD section, thereby promotes draw-bar to left movement, drives the hydrovalve spool and moves left, and pressure oil enters the right chamber of oil hydraulic cylinder, and hydraulic cylinder piston rod bounces back, and realizes the purpose of commutation.Return to original position (BC arc section) by the spring in the hydrovalve when resetting.
