- Ordering Process
F745X diaphragm remote control floating ball valve is composed of main valve, floating ball valve and nozzle system. The main valve body adopts full channel, direct current and streamline design, and adopts diaphragm or piston structure. The takeover system is made up of floating ball valves, ball valves and nozzles.
The product directly uses floating ball guide valve for liquid level control, does not need other devices and energy, simple structure, easy maintenance, control is not affected by water pressure, high accuracy of liquid level control, reliable sealing.
When the pipe feeds water from the inlet, because the ball valve and floating ball valve are often open, water enters the pool through the micro-filter, ball valve B, control room, ball valve A, floating ball valve, the main valve control room does not form pressure, the main valve opens, the water tower (pool) water supply.
When the water surface of the water tower (pool) rises to a set height, the floating ball floats to close the floating ball valve, the water pressure in the control room rises to push the main valve to close, and the water supply stops. When the water level of the pool drops, the float valve reopens, the water pressure in the control room drops, the main valve reopens and continues to supply water, keeping the set height of the liquid level.
Work characteristics
1, close and reliable. The main valve seal is sealed by rubber sealing ring. The closing power is formed automatically by the main valve control room to keep the proper closing force, and the sealing life and reliability are high.
2, easy to operate, no need for the valve equipped with electric control system. The valve opens and closes automatically with the change of the height of the liquid level.
3, the valve body uses a full channel, DC, streamlined design. The hydraulic loss is small and the energy saving effect is good.
Functions and uses
The valve is installed in the inlet pipeline of the water tower and the pool to maintain the specified height of the water tower and the pool.
This series of valve products are widely used in high-rise buildings, living areas and other water supply network system towers, pools and other facilities of liquid level automatic control.
