Product Description
F745X diaphragm remote control floating ball valve consists 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 nozzle system consists of floating ball valve, ball valve and nozzle.
This 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 pipeline feeds water from the intake end, because the ball valve and floating ball valve are usually open, water enters the pool through the micro filter, ball valve B, control room, ball valve A and floating ball valve. The main valve control room does not form pressure, the main valve opens, and the water tower (pool) supplies water.
When the water level of the water tower (pool) rises to a set height, the float ball floats to close the float valve, and the water pressure in the control chamber increases 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 of the control room drops, and the main valve reopens to continue to supply water, maintaining the set height of the liquid level.
Working characteristics
1. Close and reliable. The main valve is sealed by rubber sealing ring. The closing power is formed automatically by the main valve control room, which maintains the appropriate closing force and has high sealing life and reliability.
2. Easy to operate, no need to distribute control system for valves. The valve opens and closes automatically with the change of liquid level height.
3. The valve body adopts full channel, direct current and streamlined design. The hydraulic loss is small and the energy saving effect is good.
Functions and uses
The valve is installed on the pipeline of the inlet end of the water tower and pool to maintain the specified height of the liquid level of the water tower and pool.
This series of valve products are widely used in water tower, pool and other facilities of water supply network system such as high-rise buildings and living areas for automatic control of liquid level.
