structure and principle
The regulating valve by the main valve, the intelligent actuator and the sensor three parts is composed, according to the user need, has the heating separately and the cooling two kind of structures.
1. the heating regulating valve's structure and the principle, see attach the graphical representation:
Before the work, the main valve core is at the ajar position, the sensor is at the natural state. Joins the power source, the main valve core all opens. The medium flows in the main valve chest, by the arrow direction to carry on the heating after the valve core to Chu Rexiang. When the temperature rises to the corresponding setting value, the sensor namely has the corresponding linear signal input integration intelligence implementing agency, actuates the valve lever, the valve core to have the displacement immediately, closes the main valve core to stop the heating. When the temperature is lower than the setting value, the sensor namely has the linear signal input implementing agency, urges the valve core gradually to open, causes the medium to flow in Chu Rexiang according to the parabola characteristic, carries on the heating until the setting value. Like this is accused the medium to establish in the temperature range to control throughout, thus achieves controls the warm goal.

Note: Often said heating, cooling. In this valve, so long as the replacement valve core structure namely may realize. |
