Abstract
The utility model relates to a valve, and aims to provide an electromotive adjusting valve applied in the balanced-temperature integrated PID control loop in the distribution process of a water system. The valve comprises an adjusting valve, and further comprises an intelligent loop controller and an actuator; the actuator is connected with the adjusting valve by adopting the generally-known mechanical linkage technology; and the intelligent loop controller is connected with the actuator through a cable. The utility model has the advantages that the PID control loop and the adjusting valve areintegrated, thereby reducing manufacturing cost, increasing operating reliability, and reducing complexity of distribution and control of the entire water system.
Description
Technical field
The utility model relates to a kind of valve, a kind of specifically electric control valve that is applied to the integrated pid control circuit of temperature balance in the water system transmission ﹠ distribution process.
Background technique
Ubiquity the hydraulic misadjustment phenomenon in the water system transmission and distribution network, and the pipe network water force unbalance easily causes the waste of system's energy and the increase and the transmission ﹠ distribution effect of equipment operation noise to reduce.Generally adopt energy waste and hydraulic misadjustment phenomenon in means such as modulating valve the is installed solution water system transmission ﹠ distribution process at present, its groundwork principle is as follows, it generally comprises target measurement device (as air temperature sensor), programmable controller, final controlling element and modulating valve.The target measurement device is input to programmable controller after with signals collecting, gives final controlling element by various intelligent control loop output controlling value, and final controlling element is according to controlling value regulating and controlling valve opening.Package unit control is complicated, and costs an arm and a leg, and generally just is used for a spot of main conduit line in actual applications.
The present known electric control valve of also not finding integrated pid control circuit, the electric control valve of this integrated pid control circuit can reduce the complexity of pipe network water system control, and cost is low, reliable.
Summary of the invention
Main purpose of the present utility model is to overcome deficiency of the prior art, and a kind of electric control valve that is applied to improve in the water system transmission ﹠ distribution process the integrated pid control circuit of transmission ﹠ distribution efficiency is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of electric control valve of integrated pid control circuit, comprise modulating valve, also comprise intelligent loop control unit and final controlling element, final controlling element is connected with modulating valve by known MACHINERY JOINT, and intelligent loop control unit is connected with final controlling element by cable.
As a kind of improvement, in the described intelligent loop control unit pid control circuit module is set.
As a kind of improvement, described intelligent loop control unit comprises at least one signal input port.
As a kind of improvement, described final controlling element is angle stroke electric actuator or straight stroke electric final controlling element.
Its working principle is as follows:
(1) in intelligent loop control unit, sets control loop setting value χ
s
(2) intelligent loop control unit obtains control loop measured value χ by signal input port
p
(3) intelligent loop control unit contrast control loop setting value χ
sWith measured value χ
p, operation PID control program obtains the control signal x of unitization;
(4) final controlling element makes control loop setting value χ according to the aperture of control signal x regulating and controlling valve
sWith measured value χ
pEquate;
Advantage of the present utility model is:
(1) pid control circuit and modulating valve is integrated, reduced cost of production, increased reliability of operation.
(2) reduced the complexity that the whole water system transmission ﹠ distribution are controlled.
