Application of hfvf dynamic balance valve and flow control balance valve

Hfvf-16 dynamic balance valve is used in water systems that need flow control, especially for flow control of non corrosive liquid media such as heat supply and air conditioning. One time adjustment before operation can automatically keep the system flow constant at the required set value.

Hfvf dynamic balance valve, flow control balance valve product features

1. It can automatically balance the system flow at the required set value;

2. It can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by users, overcome the "uneven cold and heat", and improve the room temperature qualification rate of heating and air conditioning;

3. It can effectively overcome the bad operation mode of "large flow and small temperature difference", improve the energy efficiency of the system and realize economic operation.

Structural type of dynamic balance valve

The valve is mainly composed of valve body, upper and lower covers, automatic regulating valve disc, manual regulating valve disc, diaphragm and spring, as shown in the right figure:

Working principle of dynamic balance valve

The dynamic balance valve is composed of automatic regulating valve disc and manual regulating valve disc. The working pressure of the system fluid is P1, and the front and rear pressures of the manually adjusted valve discs are P2 and P3 respectively. When the manual regulating valve disc is adjusted to a certain position, the "set flow" and the corresponding fixed (P2-P3) value are manually determined. When the system flow increases, the actual value of (P2-P3) exceeds the allowable given value, at this time, the automatic regulating valve disc will automatically close down until the flow is maintained to the set flow, and vice versa.
