The utility model discloses a high-pressure electric adjusting valve. The high-pressure electric adjusting valve comprises a valve body and an adjusting shaft which is connected with the valve body. The other end of the adjusting shaft is connected with a servo motor. An encoder is arranged in the middle of the adjusting shaft, and the adjusting shaft penetrates through the encoder. The servo motor is connected with a programmable controller. According to the high-pressure electric adjusting valve, the problem that an existing valve can not accurately control the opening and closing positions of the valve is solved, automatic control of high-pressure air is achieved, high cost of the high-pressure adjusting valve is avoided, the functions of origin monitoring, limiting value protecting, preventing inertial oscillation, fatigue sealing detecting processing and the like are additionally added to a program, so that the high-pressure electric adjusting valve has the advantages of being simple in operation, safe, reliable and the like, labor intensity of workers is greatly relieved, operating errors are greatly reduced, and real-time monitoring and safe operation of opening adjusting of the adjusting valve are achieved.

Description

The high-voltage electric modulating valve

Technical field

The utility model belongs to the high-voltage electrical equipment technical field, is specifically related to a kind of high-voltage electric modulating valve.

Background technique

In the current industrial production, the valve that is used for control water, gas, the various fluids transmission of wet goods is indispensable visual plant.Wherein, electric valve is used for constituting various pipe network automation control systems in occupation of leading position.Traditional electric control valve is made up of servoamplifier and actuator's two-part.Servoamplifier compares with input signal with from the feedback signal of actuator's electric pneumatic converter, and the deviation of the two is amplified, and rotates to change valve opening with drive motor rotating band movable valve plug.Its reception and output all be analogue signal, tangible error often appears.Along with the extensive use of computer controlled system, electric valve requires on the man-machine interface interface of central control room also can telecontrol, otherwise where the valve that can not know for sure reached, and also just can not reach certain position, centre to valve exactly.

The model utility content

The purpose of this utility model is to provide a kind of high-voltage electric modulating valve, has solved the accurately problem of control valve folding position of existing valve.

The technological scheme that the utility model adopts is: the high-voltage electric modulating valve, comprise valve body, and the adjusting axle that links to each other with valve body, the other end of adjusting axle is connected with actuating motor; The middle part of adjusting axle is provided with encoder and adjusting axle passes encoder, and actuating motor is connected with programmable controller.

Characteristics of the present utility model also are,

The model of programmable controller is SIMENS CPU222PLC.

One side of valve body is provided with the tubular shape connection mouth.

The beneficial effects of the utility model are: high-voltage electric modulating valve of the present utility model has not only been realized the automatic control of pressurized gas; avoided the expensive of septum valve; and inertial oscillation is protected, prevented to additional initial point monitoring, limiting value in the program; and function such as tired sealing detection processing; have advantages such as simple to operate, safe and reliable; thereby significantly reduced staff's labor intensity and operate miss, realized real-time monitoring and safety operation that control valve opening is regulated.

Description of drawings

Fig. 1 is the structural representation of the utility model high-voltage electric modulating valve.

Among the figure, 1. valve body, 2. adjusting axle, 3. encoder, 4. actuating motor, 5. programmable controller, 6. connection mouth, 7. process control machine.

Embodiment

Below in conjunction with embodiment the utility model is elaborated.

Be illustrated in figure 1 as the structural representation of the utility model high-voltage electric modulating valve, comprise valve body 1, the adjusting axle 2 that links to each other with valve body 1, the other end of adjusting axle 2 is connected with actuating motor 4; The middle part of adjusting axle 2 is provided with encoder 3 and adjusting axle 2 passes encoder 3, and actuating motor 4 is connected with programmable controller 5.

The model of programmable controller 5 is SIMENS CPU222PLC.

One side of valve body 1 is provided with tubular shape connection mouth 6.

During work, actuating motor 4 is connected with programmable controller 5, programmable controller 5 links to each other with process control machine 7 again, the aperture that shows and control the high-voltage electric modulating valve by process control machine 7, concrete grammar is: the user imports the target aperture of high-voltage electric modulating valve according to actual needs by process control machine 7, programmable controller 5 is measured the difference of the current actual aperture of target aperture and modulating valve then, and this difference is transferred to actuating motor 4, actuating motor 4 rotates forward or backwards, driving adjusting axle 2 rotates, and then the aperture of regulation valve body 1 reaches the opening value of user's input, so just control MEDIA FLOW and crossed the flow size of high-voltage electric modulating valve, finally reached the purpose of pilot pressure.

The circuit theory of high-voltage electric modulating valve is: the needed valve target aperture of input in process control machine 7, this aperture is converted to pulse number and feeds back to programmable controller 5, programmable controller 5 compares to control direction of motor rotation with actual pulse number and the target pulse number of valve then, encoder 3 is along with pulse signal is sent in the rotation of motor, and gives programmable controller 5 and accurately count.If the target pulse number is greater than current umber of pulse, programmable controller 5 is controlled actuating motors 4 forward rotation, and the real-time pulse number up increases counting; Otherwise, programmable controller 5 control actuating motors 4 backward rotation, the real-time pulse number down subtracts counting.When the real-time pulse number equals target pulse and counts, illustrate that valve has been adjusted to the target aperture of setting by current aperture, actuating motor 4 stops to regulate, and programmable controller 5 stops counting.Simultaneously, the real-time pulse number conversion of programmable controller 5 is that current aperture shows at process control machine 7.

The effect of connection mouth 6 is used for being interconnected with one another when a plurality of high-voltage electric modulating valve valves use together.

By the way, high-voltage electric modulating valve of the present utility model has solved the accurately problem of control valve folding position of existing valve.And high-voltage electric modulating valve of the present utility model has not only been realized the automatic control of pressurized gas; avoided the expensive of septum valve; and inertial oscillation is protected, prevented to additional initial point monitoring, limiting value in the program; and function such as tired sealing detection processing; have advantages such as simple to operate, safe and reliable; thereby significantly reduced staff's labor intensity and operate miss, realized real-time monitoring and safety operation that control valve opening is regulated.
