Embodiment
A kind of motor-driven plug-in mounting servovalve; Comprise the gland 3 of a valve body 1, spool 2, band nut and return opening, spool controller 4, motor bearing 5, slip coupling 6, motor 7, spring 8 etc., runners such as P, B, O are arranged on the valve body 1, a plurality of steps are arranged on the spool controller 4 and be loaded in the spool 2; There is runner to guide to high pressure oil in the step of spool controller 4 by P on the spool 2; One end of spool controller 4 has the screw thread screw thread, and this screw thread screw thread matches with nut on the gland 3, and spring 8 is equipped with on spool 2 tops; Spring 8 is glanded 3 and is encapsulated in the valve body 1, and gland 3 links to each other with valve body 1 through bolt.
When motor rotates, drive the feather key motion through slip coupling, move axially thereby drive 4 generations of spool controller; Spool 2 is followed the tracks of spool controller 4 and is produced identical moving, and realizes opening or closing valve port, accomplishes valve port control; Only need accurately sense of rotation, rotating speed and the corner of control motor; Just the aperture and the response time of valve port be can accurately control, completed percentage control or servocontrol exported to the flow of O mouth to B mouth or B mouth thereby control the P mouth accurately.And,, thereby adopt very little motor just can realize threeway or many logical plug-in mounting servovalve control of very big flow, the trouble of having removed multistage amplification from because spool controller (being the control type spool) is very little.
Like Fig. 2, Fig. 3, shown in Figure 4, the motor-driven plug-in mounting servovalve that the utility model provided is divided into the gland 3 of motor 7, valve body 1, spool 2, spool controller 4 and band nut sleeve; The screw thread of spool controller 4 one ends and the nut on the gland are coupled, and link to each other with motor 7 through slip coupling 6, and threeway or four-way are made in the other end of spool controller 4; Match with the runner on the spool 2, spool 2 ends Returnning spring 8 is arranged and with gland seal in valve body 1, motor 7 passes through motor bearing 5 and links to each other with valve body 1; When motor 7 rotated, spool controller 4 produced moving axially of making progress under the effect of nut, and spool 2 is followed 4 generations of spool controller and moved axially; Open valve port, the high pressure oil of P mouth flows out through the B mouth, the driving oil cylinder motion; When the motor counterrotating, spool 2 moves downward, and closes the high pressure hydraulic fluid port; The B mouth is connected oil return; The corner of change motor and the size that direction just can change opening and B mouth are connected high pressure or low pressure, thereby can change the output and the input flow rate of motor-driven plug-in mounting servovalve valve port, realize the function of Proportional valve.If through the speed and the position of sensor oil cylinder, rely on the speed and the position data of oil cylinder to control motor, just can realize the accurate control of direction, speed and the position of oil cylinder, the function of completed percentage valve and servovalve realizes multi-purpose valve.
The motor-driven plug-in mounting servovalve that the utility model provided; Unite use with closed-loop adjustment, can be equivalent to high-precision flow servovalve, if unite the oil cylinder displacement detector again; Then can realize direction control, speed controlling and the positioning control of oil cylinder simultaneously; With simple device, satisfy maximum work requirements, practical.
The motor driving plug-in mounting servovalve that the utility model provided, spool controller wherein can be threeway or four-way type, even how logical, and the screw thread on it can be single head or bull, and helical pitch also can have multiple; Coupling wherein also can adopt any one with rotation and straight line motion function; Spool wherein can adopt any viable material to process; Runner quantity and shape on its valve body also can be set as required; Its motor can be directly installed on the valve body that has extended, and the use of saving the motor bearing reduces cost; Nut on its gland and the gland can be made of one, and also can make two parts and connect, and uses more flexible; Its motor can adopt various types of motors, comprises direct current generator, AC motor, stepper motor, actuating motor etc., if adopt stepper motor, cooperates relevant device, and then this motor-driven plug-in mounting servovalve just can be processed digital plug-in mounting servovalve.
