Constant flow valve and cross flow regulating valve are variable resistance device, it is a differential pressure as power fluid, and based on the system operating mode (differential pressure) change, automatically change the drag coefficient, maintain a constant flow valve and cross flow, constant through the flow of the slip road to achieve the balance of the whole system flow distribution, uneven and eliminate the phenomenon. Under the condition of sufficient total flow, the flow changes of each branch will not affect each other, and the system is relatively stable.
 
Constant flow valve and constant flow regulating valve is different:
 
1, only a constant flow valve disc, felt directly by the disc of valve differential pressure before and after the change valve resistance action, can be a "straight acting variable resistance valve", it can't be online regulate traffic, so using constant flow valve cannot be implemented change traffic running, only seen in some central air conditioning system.
 
2, constant flow regulating valve is their compensation mode: variable resistance movement, it will have two disc, one is the valve disc, used for compensating the differential pressure before and after the orifice, thus can become "compensating resistance regulator" the principle is: use before and after the orifice differential pressure, the driving force of the action as a compensation, compensation and keep the stability of throttle orifice differential pressure before and after, so as to maintain a constant flow rate, adjusting the size of the orifice is different flow rate can be obtained. Therefore, it can regulate the flow rate. It can also keep the flow constant when the water conservancy condition of the system changes. In the system, it can not only keep the flow of each branch constant to realize the balanced transmission and distribution of flow, but also change and adjust the flow of each branch at any time to achieve the dynamic balance. If the flow rate is adjusted twice every year from the initial cold to the severe cold and from the severe cold to the final cold, the energy saving operation mode of "quality adjustment of flow rate by stages" can be realized. Constant flow control valve regulation is simple and convenient, but for the larger system, two times a year to adjust is still a burden, and the constant flow control valve price is high, although it can be recovered in the year, but still have a large psychological pressure on users.
