& Self-operated flow control valve
National patent number: . (Counterfeiting will be investigated)
() type self-operated flow control valve (self-operated balancing valve) is an intuitive and simple flow adjustment control device. When this valve is used in the network, the flow rate can be set directly according to the design. Under the action of water, the valve can automatically eliminate the residual pressure head of the pipeline and the flow deviation caused by pressure fluctuations. The set flow rate remains unchanged no matter how the system pressure changes. , these functions of the valve enable the pipe network flow adjustment to be completed at one time, turning the network adjustment work into a simple flow distribution, effectively solving the hydraulic imbalance of the pipe network.
Performance and characteristics of self-operated flow control valve
. The flow rate can be set according to the design or actual requirements, and it can automatically eliminate the pressure difference fluctuation of the system and keep the flow rate unchanged.
.The flow rate display values are all randomly calibrated flow rates on the test bench (/).
.Completely solve the contradiction between large pressure difference at the proximal end and small pressure difference at the far end.
. Overcome the phenomenon of uneven heating and cooling in the system and improve the quality of heating (cooling) supply.
.Reduce the design workload and no need to repair the pipes
.Reduce the amount of circulating water in the system and reduce the system resistance.
. Eliminate flow redistribution when switching heat sources in multi-heat source pipe networks.
. Reduce the difficulty of network adjustment and simplify the complex network adjustment work into simple traffic distribution.
Technical parameters of self-operated flow control valve
． Medium temperature ~℃.
． Working pressure difference.
Selection
． Can be selected according to the pipe diameter.
． It can be selected according to the maximum flow rate and the flow range of the valve.
Installation and debugging
． The flow direction of the medium should be consistent with the flow arrow on the valve body.
． After installation, set the flow rate according to the needs of the pipeline connected in series.
． Check whether the pressure difference across the valve is within the working pressure difference range.
． Avoid operating the valve at minimum flow as much as possible.
