Regus Regus imported self-operated flow control valve
The self-operated flow control valve is a new type of regulating valve. Compared with the manual regulating valve, it has the advantage of being able to adjust automatically. Compared with the electric regulating valve, it has the advantage of not requiring external power, and the application practice proves that it is in closed water circulation. In the system (such as hot water heating system, air conditioning refrigeration system), the correct use of this valve can easily realize the flow distribution of the system; the dynamic balance of the system can be realized; the debugging of the system can be greatly simplified; the work of the
pump can be stabilized. Status, etc. Therefore, the self-operated regulating valve has broad application prospects in the heating and air conditioning project.

Regus Regus imported self-operated flow control valve definition
The function of the self-operated flow control valve is to maintain a constant flow through the valve in the case of a change in the pressure difference between the inlet and the outlet of the valve, thereby maintaining a controlled object (such as a loop, a user, a device, etc.) in series with the valve. The flow rate is constant, and the name of the self-operated flow control valve is more, such as self-operated flow balance valve, constant flow valve, self-balance valve, dynamic flow balance valve, etc., various types of self-operated flow control valves, each structure Different, but working similarly.
The self-operated flow control valve is structurally a two-valve combination consisting of a manual regulator valve block and an automatic balancing valve block, as shown in Figure 1. The purpose of the manual adjustment valve group is to set the flow rate. The function of the automatic balance valve group is to maintain a constant flow rate.
For the manual adjustment valve group, KV in the flow rate G=P2-P3 is the flow coefficient of the valve port of the manual control valve, and P2-P3 is the pressure difference on both sides of the valve port of the manual adjustment valve. The size of Kv depends on the opening degree, the opening degree is fixed, and Kv is a constant, so as long as P2-P3 does not change, the flow rate G does not change. The constant P2-P3 is controlled by the automatic balancing valve block. For example, if the inlet and outlet pressure difference P1-P3 is increased, the automatic balancing valve group is closed by the action of the pressure sensitive membrane and the spring, so that P1-P2 is increased, thereby maintaining the P2-P3 constant; otherwise, the P1-P3 is decreased. Then, the automatic balancing valve group is opened to reduce P1-P2 and maintain the constant P2-P3.
Each opening of the manual adjustment valve group corresponds to a flow rate, and the relationship between the opening degree and the flow rate is calibrated by the test bench test, and is equipped with an opening display and a locking device.
