Self balancing valve working principle

by:Mech     2020-08-08
Self-reliance type balancing valve can be in the absence of an external power supply, automatic flow balance of the system. Self balancing valve is by keeping orifice ( Fixed aperture) Qualified traffic pressure difference before and after a while, therefore, can also be called constant flow valve. Constant flow valve function object is flow, able to lock in the amount of water that flows through the valve and not against the balance of the resistance. He was able to solve the problem of system dynamic disorder: in order to maintain a single chiller, boiler, cooling tower, heat exchanger efficiency of the equipment, is the need to control the equipment flow fixed in rating; From the end of the system, in order to avoid dynamic adjustment influence each other, also need to be in the end of the device or the branch flow restrictions. It should be noted that in the design for the disadvantage of flow control Industrial Valves is the valve type have minimum differential work demand, the general product requirements minimum work 20 kpa pressure difference, if the installation on the way back to the most adverse, certainly will require adding 2 meters water circulating pumps work head, so should be taken to the proximal installation, remote method. When users away from the heat source distance is greater than 80% of the heating radius, do not have to install flow control Industrial Valves type of this kind of self-reliance.
