Abstract
The utility model relates to an electromechanical integrated numerically controlled needle-shaped valve which is used for the experimental equipment in various chemical engineering and geology experiments and particularly used for various kinds of automated experimental equipment. The electromechanical integrated numerically controlled needle-shaped valve is provided with a valve body and a needle-shaped valve core, and is characterized in that the upper end of the valve core is connected with a decelerator with big velocity ratio and a numerically controlled electric machine; a standard industrial control interface is arranged in the utility model, an adapting module which controls the numerically controlled electric machine is inserted in the standard industrial control interface, and the control interface is connected with a central control computer which can be mutual through a standard serial port. Because of the adoption of the electromechanical integrated form of the central control computer and the control interface with an action element, the opening value of the valve can be altered by the method of automatic control, and thus the operation is convenient.
Description
A kind of electromechanical integrated digital-control needle valve, it is used for the experimental facilities of various chemical industry, geological experiment, in the particularly various automation experiment equipment.
In chemical industry and GEOLAB, for simulating various productions and geological condition, seek best chemical industry parameter, use various needle values that the liquid or the gas of various addings or output are controlled.In whole experiment flow, each valve need often be adjusted.Now usedly in the laboratory be mostly manual needle value, it is by manual tune.In experiment, the experimenter shows manual tune by the various measurements of observation.This needs operator that very skilled operation skill is arranged on the one hand, and labor intensity is big, be easy to generate operate miss, on the other hand, mostly experimental measurement is digitizing, electromechanical integrated structure now, and artificial manual tune is also used in valve control, has become the bottleneck problem of whole Experimental Establishment automation.
The purpose of this utility model is a kind of electromechanical integrated digital-control needle valve of invention, adopts electromechanical integration technology to link to each other with other measuring and controlling equipment, can be by the opening value of digital control change valve, and easy to operate.
The utility model as shown in Figure 1, it has valve body 1, spool 2, it is characterized in that: spool 2 upper ends are connected with large speed ratio retarder 3 and numerical-control motor 4, standard industrial control 5 is arranged, in standard industrial control 5, be inserted with and link to each other with numerical-control motor 4 and its adaptation module of controlling 6, standard industrial control 5 by the standard serial communication interface with can link to each other with the total central control computer 7 of other measuring and controlling equipment.
The utility model links to each other with other measuring and controlling equipment by central control computer 7 in use.After central control computer 7 is gathered whole experiment parameter, by software calculating is set, obtain valve opening adjusted value of the present utility model.During adjustment, central control computer 7 sends address gating signal by the standard serial communication interface, and by standard industrial control 5 gating adaptation module 6, computer sends signal and makes numerical-control motor 4 forward or reverse then, valve opening is increased or reduces.The variable quantity of valve opening can be realized by the timing interruption control of central control computer 7.Because the rotating speed and the revolution valve amount of movement parameter of numerical-control motor 4 can deposit central control computer 7 in advance in, calculate time of electrical power by machine solution, obtain the aperture adjusted value current"on"time by control numerical-control motor 4.The control of valve opening variable quantity, also can adopt feedback, after numerical-control motor 4 in central control computer control the utility model rotates, whether reach requirement and control stopping of numerical-control motor 4 by measuring other parameter (as reaction temperature, pressure or output flow etc.).
The utility model adopts central control computer and standard industrial control to add this electromechanical integration form of actuator, can automatically adjust by the aperture of digital computer technology to needle value, particularly can be connected as a single entity with other measuring and controlling equipment, use measurement parameter to carry out feedback control, can obtain high control precision and speed of response faster.Electrification drives, and is easy to operate.
In the utility model, be simplified structure, also can save standard industrial control 5 and central control computer 7, adaptation module 6 is changed into the circuit switch of manual motor 4 clockwise and anticlockwise.
The numerical-control motor 4 that is adopted in the utility model can use the miniature instrument Wechselstrommotor, produces low speed synchromotor series as Hangzhou instrument motor factory.For realizing clockwise and anticlockwise, can use two to turn to different motor joinings, reach the purpose of forward and reverse control by different electrical powers.Motor of the present utility model also can use dc micro-motor, and bigger starting torque is arranged, and by the change of electric power polarity, the motor sense of rotation is changed.Can also use the autosynchronous motor of making rotor of rare earth permanent-magnetic material, drive with variable-frequency power sources, adjust turning to of motor by the phase relationship of adjusting variable-frequency power sources, for example the patent No. is the patent of CN89209067.
In the utility model, retarder 3 can use multistage common retarder, also can use harmonic gear reducer, and bigger reduction speed ratio is arranged.Can also use as " a kind of high-ratio differential speed reducer " of number of patent application, very big reduction speed ratio and very little volume are arranged as CN91103847.The utility model can also be made an integral body to motor and retarder, and for example number of patent application is the patent of CN91103795 " a kind of differential reducing electric servo unit ", and littler composite structure size is arranged.
In the utility model, standard industrial control 5 can be selected the I/O K32 of U.S. ME company (MECHATRONICEQUIPENT INC.) for use, or the PB16AH of U.S. OPTO 22 companies, adaptation module 6 can be selected the OAC5 module of U.S. OPTO 22 companies for use.Central control computer 7 can be selected the LC4 controller of U.S. OPTO 22 companies for use, also can select the PCS-1 industrial process work station of ME company for use.
