Abstract
The invention provides a rotary valve driving device which is characterized in that a guide rod is parallelly arranged in a case body; a sliding block is arranged on the guide rod; a screw rod is arranged on the case body at the middle part of the guide rod; the screw rod penetrates through the sliding block in a thread fit mode; a motor is arranged on the case body at one end of the screw rod; the output shaft of the motor and the end part of the screw rod are connected and fixed; a driving shaft, the guide rod and the screw rod are vertically arranged on the case body through bearings; the bearings at two ends of the driving shaft are respectively fixed by a left bearing cover and a right bearing cover; a shift fork is arranged and fixed on the driving shaft through keys; a shift shaft is arranged at the side face of the sliding block; the opening part of the shift fork is in bridge joint with the shift shaft; and the upper port part of the case body is sealed by a case cover.
Description
Technical field
The present invention relates to a kind of drive unit, particularly a kind of turning valve drive unit belongs to the valve actuator technical field.
Background technique
Use the electro-mechanical wave device on part turning valves such as ball valve, butterfly valve at present; The swirl gear of hydraulic oil cylinder driving mainly contains three kinds of pinion and racks, pull-rod type mechanism, piston rod mechanism, and being characterized in exporting torque curve is straight line, with the threshold torque characteristic curve that opens of ball valve, butterfly valve be a parabola; Promptly at the end moment of torsion is big in opening and closing; Interstage, little characteristic was not inconsistent, and the output torque is less, unsuitable drive unit as heavy caliber ball valve, butterfly valve.
Summary of the invention
The objective of the invention is to: a kind of turning valve drive unit is provided, overcomes the existing above-mentioned defective of existing turning valve device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of turning valve drive unit, and it is the inside that guide rod is installed in abreast casing, and a slide block is installed on guide rod; Slide block has the degrees of freedom of sliding along guide rod, and a screw mandrel is installed on the casing of guide rod intermediate portion, and screw mandrel passes slide block with the mode of screw-thread fit; One motor is installed on the casing of screw mandrel one end, and it is fixing that the output shaft of motor is connected with the end of leading screw, with live axle and guide rod, leading screw with vertical state; With Bearing Installation on casing; The bearing at live axle two ends is fixing with the right bearing lid with the left bearing lid respectively, on live axle, installs and fixes shift fork with key, in the side of slide block one dial axis is installed; Grade position of opening of shift fork is connected across above the dial axis, and case lid is with the upper oral part sealing of casing.
Beneficial effect: output torque of the present invention is big, suitable drive unit as heavy caliber ball valve, butterfly valve, and volume is little, simple in structure, in light weight, adopts the integrated structure, and shell protection is good, and Installation and Debugging are convenient.
