Abstract
The utility model discloses a valve stem stroke measurement control device, which comprises a control motor, a speed reducer, a transmission shaft, a measuring shaft, a measuring ring with the magnetic poles, a magnetic inductor, an electric counting controller and an electric display. The measuring ring is arranged on the measuring shaft; the magnetic inductor which is connected with the electric counting controller is arranged around the measuring ring. The data of the stroke of the valve stem is measured through the magnetic inductor, is recorded in the electric counting controller and is output by the electric display. Meanwhile, the electric counting controller can control the stroke of the valve stem accurately.
Description
The utility model relates to the valve rod travel measuring and controlling of using in a kind of electric valve.
In the widely used electric valve of industrial field, valve rod is the critical piece of valve opening.Therefore,, can learn the opening degree of valve, and can accurately control the unlatching of valve by measurement to the valve rod travel in the electric valve.At present, the measuring and controlling that is used to measure valve rod travel in electric valve comprises control motor, retarder and the valve rod travel measuring mechanism that is connected by retarder.Above-mentioned valve rod travel measuring mechanism is generally the display list of the gear train be made up of a plurality of gears and the control of this gear train and forms, because volume, the weight of this gear train are bigger, make that volume, the weight of whole electric valve are also bigger, be not easy to on-the-spot installation and use; Because the mechanical measurement mechanism that gear train constitutes is difficult to implement control accurately to controlling motor, therefore be difficult to satisfy the needs of accurately controlling in the industrial production simultaneously.
The purpose of this utility model provides a kind of valve rod travel measuring and controlling, uses this device can alleviate the weight and volume of electric valve, and makes the unlatching control of valve more accurate.
For achieving the above object, the technical solution adopted in the utility model is: by control motor, retarder, transmission shaft, measurement axis, be furnished with the measuring ring of magnetic pole, magnetic inductor, in the valve rod travel measuring and controlling that electronic counting controller and electronic console are formed, retarder is connected with an end of control drive axle of motor and measurement axis, measuring ring is arranged on the other end of measurement axis, arranged around in measuring ring has magnetic inductor, described magnetic inductor is connected with the electronic counting controller, electronic counting controller and electronic console, the control motor connects respectively.By above-mentioned connection, make of the measurement axis output of control rotating speed of motor by being connected with retarder, like this, measuring ring by being arranged on measurement axis one end and be arranged in magnetic inductor around the measuring ring and can measure the stroke of the valve rod that the control motor controlled by the valve rod controller and be recorded in the electronic counting controller again, through the electronic counting controller, measurement result is exported by electronic console, and simultaneously the stroke of the valve rod that can be controlled by the valve rod controller the control motor according to measurement result is controlled.
Because valve rod travel measuring and controlling described in the utility model has adopted measuring ring, magnetic inductor, electronic counting controller and the electronic console that is furnished with magnetic pole, make that volume of the present utility model is less, weight is lighter, measuring accuracy is higher, be convenient to accurate control, thereby reach accurate control the electric valve opening degree to valve rod travel.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a theory structure schematic representation of the present utility model;
Fig. 2 is the schematic representation that is furnished with three groups of magnetic poles and three magnetic inductors of measuring ring arranged around on the measuring ring.
The utility model is achieved in that with reference to figure 1.Valve rod travel measuring and controlling 11 shown in the figure comprises control motor 1, retarder 2, transmission shaft 4, measurement axis 5, the measuring ring 6 that is furnished with magnetic pole, magnetic inductor 7, electronic counting controller 8 and electronic console 9, wherein, retarder 2 is connected with the transmission shaft 4 of control motor 1 and an end of measurement axis 5, measuring ring 6 is arranged on the other end of measurement axis 5, arranged around in measuring ring 6 has magnetic inductor 7, described magnetic inductor 7 is connected with electronic counting controller 8, and electronic counting controller 8 is connected respectively with electronic console 9, control motor 1.By above-mentioned connection, make measurement axis 5 outputs of rotating speed by being connected of control motor 2 with retarder 2, like this, when control motor 1 was advanced by valve rod controller 10 drive valve rods, its stroke can reflect by measurement axis 5.Therefore, the measuring ring 6 by being arranged on measurement axis 5 one ends and be arranged in the stroke that magnetic inductor around the measuring ring 6 can be measured the valve rod 3 that control motor 1 controlled by valve rod controller 10, and the trip data are recorded in the electronic counting controller 8.Through electronic counting controller 8, measurement result is by electronic console 9 output, and the stroke of the valve rod 3 that can be controlled by valve rod controller 10 control motor 1 according to measurement result is controlled simultaneously.
In specific implementation process of the present utility model, the number of magnet poles of arranging on measuring ring 6 can measurement control accuracy according to actual needs be determined, but should arrange one group of magnetic pole at least, be the stable and precision that guarantees to measure, above-mentioned magnetic pole on measuring ring 6 should evenly be arranged.
Equally, number at the magnetic inductor 7 of the arranged around of described measuring ring 6 also can be determined according to the needs of actual measurement control accuracy, be at least one, if the number of the magnetic inductor 7 that adopts is more than one, then be stablizing and precision of guaranteeing to measure, described magnetic inductor 7 should evenly be arranged around measuring ring 6.On the above-mentioned measuring ring 6 around the layout of magnetic pole and the measuring ring layout of magnetic inductor with reference to figure 2.
The utility model in the specific implementation, described electronic console 9 can adopt liquid crystal display, also can adopt the nixie tube display device.
Need to prove that control motor described in the utility model can also can use as the valve rod controller in retarder 2 reality that be adopted simultaneously simultaneously as the control motor of valve rod 3, and then replace the valve rod controller 10 among Fig. 1.
