Digital display flow and pressure differential valve
Product description:
National patent number: .(Counterfeiting must be investigated)
The digital display flow and pressure differential valve is made in the original Zili On the basis of the differential pressure valve, a display function is added. This function can adjust and set the pressure difference directly according to the flow rate. Provide important digital basis for system balance adjustment and energy-saving operation.
The application of digital flow differential pressure valves in the pipeline network can automatically eliminate the residual pressure difference in the pipeline network and the flow changes caused by pressure fluctuations, and keep the user's inlet and outlet pressure differences constant. It helps to stabilize the system operation and effectively solve the imbalance of water conservancy balance in the pipe network. It is especially suitable for household metering or automatic control systems. Can save energy %.
Performance characteristics
Digital display part:
The display is separated from the valve body, and the displayed data can be taken at any time.
The display is fully sealed, moisture-proof and waterproof.
, automatic sleep function, battery design life of more than ten years.
The flow movement movement is equipped with a circular stainless steel anti-fouling cover. Small debris will flow through the valve from the gaps around the anti-fouling cover.
There is no power supply in the valve body, and there is no need for display or flow movement core failure, which does not affect the operation of the differential pressure valve.
The rotor of the flow movement core adopts stainless steel shaft agate as bearing, which has little wear and no rust.
, imported chip reading and writing, display accuracy. %.
Pressure difference control part:
This valve has a double valve disc structure, with small unbalanced force and compact structure
It can automatically constant the user pressure difference, absorb the pressure fluctuations of the external network, and is self-sustaining and controlled. series, the system is self-adjusting
, a cut-off valve is installed at the front end of the control conduit, with the function of automatically eliminating blockage
, using mixed pressure technology, stepless adjustment, the control pressure difference has a large adjustable range
, pressure difference Accurate calibration, high adjustment accuracy
, using external pressure guide structure, easy to fold and assemble
, the valve port and valve core are all copper, and the designed service life is more than ten years.
Technical parameters:
, nominal pressure.
, medium temperature ℃.
, Working pressure difference range..
, Control pressure difference setting value:. Control pressure difference adjustable range..
, Pressure guiding tube length:.
, Pressure guiding Pipe connection size: /& pipe thread.
Installation Notes
． The installation direction must be consistent with the direction of water flow
. A cut-off valve is installed at the connection between the front end of the control conduit and the water supply pipe for use during debugging or sewage discharge.
