What is the working principle of hydraulic balance valve?

The principle of the balance valve is that there is reverse adjustment in the valve body of the balance valve. When the pressure at the inlet increases, it automatically reduces the diameter and reduces the change of flow, and vice versa. If the connection is reversed, the regulating system will not work. Moreover, the regulating valve is directional, and the reverse pressure can even reduce or even close the flow.

Because the balance valve is installed for better heating, there is no problem of reverse installation. If it is anti-installation, it is a human error, and of course it will be corrected. Balance valve belongs to the category of regulating valve, and its working principle is to change the flow resistance of fluid flowing through the valve by changing the gap between the valve core and the valve seat, so as to achieve the purpose of regulating the flow.

Extended data

Performance characteristics of hydraulic balance valve;

1, with ideal regulation performance;

2. Excellent cut-off function;

3. Open display accurate to110 period;

4. The theoretical flow characteristic curve is an equal percentage characteristic curve;

5. National patent opening and closing locking device;

6. Every whole circle has a related flow coefficient. As long as the pressure difference between the two ends of the valve is measured during debugging, the flow through the valve can be calculated conveniently.

7, PTFE and silica gel seal, reliable sealing performance;

8. The internal components are made of YICr 18Ni9 or copper alloy, which has strong corrosion resistance and long service life.
