Drive automatic control refers to the devices used in automatic control systems for communication devices of automatic control, for example, the device of the PID controller, the computer or controller, which in General can be called regulating devices, shut-off and regulating bodies, consisting of electropneumatically or electrohydrodynamically associated with the actuators. These devices may find wide application in various industries for automatic control of technological processes.
There are known various devices for automatic control, which uses a variety of pneumatic or hydraulic actuators, connecting the electrical output of the regulating devices with shut-off and regulating bodies, such as the well-known distributors 4/3 controlled by an electromagnet or at least known electropneumatic converters of the type "the nozzle-valve"associated with pneumatic or hydraulic actuators, such as pneumatic or hydraulic cylinder is double-acting.
The disadvantages of the known devices is the complexity and unreliability in the work due to the need of a centralized supply pneumatic or g is draulically environment under pressure on these devices.
The aim of the invention is to increase the reliability of the device by simplifying its design.
This goal is accomplished through the electrical connection of the secondary output of the regulating device of the automatic control system with electric entrance micronanotechnology device, such as a microcompressor or Micronesian, pneumatic or hydraulic output of which is connected to at least one input pneumatic or hydraulic actuator, for example a pneumatic or hydraulic cylinder.
The device illustrated by the following drawings:
Figure 1 is a pneumatic diagram of the device.
Figure 2 is a pneumatic diagram of the device.
Figure 3 is a pneumatic diagram of the device.
The actuator includes a cylinder 1, which is the pneumatic or hydraulic actuating mechanism installed therein a piston 2 which is mechanically connected with the rod 3, which is intended for connection with regulating or shut-off and control bodies of the devices for automatic control or automatic control system. Micromagnetism device 4, for example, the microcompressor or Micronase associated, for example, mechanically with its actuator 5, a pneumatic or hydraulic output of which is connected with them of the inputs of the cylinder 1, for example, the first entry of this cylinder, by means of pipe 6, with the same pipe as the output of the cylinder 1, are connected to the beginning of the pipe 7, the end of which is installed release valve 8 with an electric actuator 9, for example with electrocorundum. The second similar to the first micromagnetism device 10, United, for example, mechanically with its actuator 11, a pneumatic or hydraulic output of which is connected by means of pipe 12 with the other, opposite the first, the second input of the cylinder 1. With the pipe 12, as with the second outlet of the cylinder 1, are connected to the beginning of the pipe 13, the end of which is installed the bleeding valve 14 with an electric actuator 15.
The terminal 16 is intended for connection of electrical input of the claimed device with electrical outlet regulating device, with its total output, which through a common electric wire 17 is connected simultaneously with the actuators 5 and 11 and with electric actuators 9 and 15. Terminal 18 is intended for connection of electrical input of the claimed device with electric control the output of the regulating device, for example with a pulse signal "more", and through the electric wire 19 is connected simultaneously with the actuator 11 and the electric actuation mechanism is SMOM 9. Terminal 20 is designed for coupling the electrical input of the claimed device with electric control the output of the regulating device, for example with a pulse signal is less than, and through the electric wire 21 is connected simultaneously with the actuator 5 and an electric actuator 15 (figure 1).
Release valve 8 may be pneumatic or hydraulic actuator 22, which tube 23 connected to the pipe 12, similar to the bleeding valve 14 may be of the pneumatic or hydraulic actuator 24, which tube 25 connected to the pipe 6 (figure 2).
When using reverse micronanotechnology device 26, such as reverse microcompressor or reverse Micronesia, one of its variables outputs connected to the first input cylinder 1 by means of pipe 27, and the other AC output connected to a second input of the cylinder 1 by means of pipe 28 and to its reverse drive 29 summed up the electrical wires 17, 19 and 21 through which the regulating device controls the direction of action of the actuator 29, and through him the direction of the discharge reversing micronanotechnology device 26.

Micromagnetisme device 4, 10 and 26, including their drive 5, 11 and 29, are signal transducers that goes with the regulating device, such as a transducer electrical signal into a pneumatic or hydraulic signal.
The device works in the following way:
The electrical signal from the control device, for example, "more", the electric wire 19 is supplied to the actuator 11, which affects micromagnetism device 10, which will begin pumping a gaseous medium, e.g. air, or a fluid, for example water or oil, in the cylinder 1, for example on the piston 2, which begins to move to the left side, at the same time this signal is applied to the electric actuator 9, opening the valve 8, is connected through pipe 7 to the opposite entrance of the cylinder 1, the currently executing function exit towards the entrance, through which is pumped the environment, venting this Wednesday from under the piston 2, eliminating or reducing the magnitude of the back pressure of this environment under the piston 2. Quite a similar process occurs when a signal less than the electrical wires 21 on the actuator 5 and the electric actuator 15, in this case micromagnetism device 4 starts the t to escalate the environment under the piston 2, and valve 14 begins to pit it on this piston, eliminating the back pressure of this environment, and the piston 2 begins to move to the right. If the control signal, for example,"+", served separately on lines 19 or 21, depending on the deviation of a given technological parameter, the actuator 11 and the electric actuator 9, connected in parallel, the motor 4 and an electric actuator 15, connected in parallel, and General reference signal, for example," -", may be supplied continuously to the actuator 5 and 11, the electric actuators 9 and 15 at the same time.
When using pneumatic or hydraulic actuator 22 or 24 control signal, for example,"+", with the regulating device podaetsya only drive 5 or the actuator 11 with the constant "-", which, when injecting the medium into the cylinder 1, the piston 2 or the piston 2, and the tube 23 and the tube 25, to the actuators 22 and 24, opening the release valve 8 or 14, the point of release where cylinder 1 is located on the opposite side of the point of discharge into the cylinder 1 in relation to the piston 2, thereby eliminating or decreasing the pressure of the environment, hinder the advancement of the piston 2.
When using reverse micronanotechnology the device 26 control signals, for example,"+", with the regulating device are fed through the electric wire 19 or electric wire 21 on its reverse drive 29, the feed is constant "-", which controls the direction of the discharge micronanotechnology device 26, a pressure medium to the piston 2 or under his pipes 27 or 28, and simultaneously evacuated from the from the cylinder 1 opposite the point of injection into the cylinder 1 in relation to the piston 2, thereby eliminating or decreasing the pressure of the environment, hinder the advancement of the piston 2. Thus it is enough, at least one micronanotechnology device for the requested drive.
