In many fields such as water conservancy and water supply, industrial production and building water supply and drainage, the stable control of liquid level is the key to ensure the normal operation of the system.

As an automatic liquid level control valve without external power and purely driven by machinery, the ball valve, with the core advantages of simple structure, stable operation and no manual duty, has become the core supporting accessories of various water tanks, water towers, reservoirs and liquid storage equipment. It is widely used in civil buildings, agricultural irrigation, municipal water supply and other scenes, and is an indispensable basic valve equipment in the modern fluid control system.

The operation core of the float valve relies on the buoyancy principle and the lever drive mechanism. No external power supply and intelligent control system are required for the overall operation. The valve can be automatically opened and closed by relying on the change of the medium liquid level to complete the cycle operation of water replenishment and water stop.

When the liquid level in the liquid storage equipment drops, the floating ball will naturally sink with the liquid level, drive the lever mechanism to rotate through the valve rod, open the valve body channel, and the medium in the pipeline will automatically flow into the equipment to complete the water replenishment operation; As the liquid level continues to rise, the floating ball floats synchronously and reversely drives the lever mechanism to apply pressure. When the liquid level reaches the preset maximum threshold, the valve body channel is completely closed to accurately cut off the inflow of medium and eliminate overflow and overflow problems. The whole set of operation process is repeated and the whole process is operated automatically without manual intervention.

The remote control float valve is an improved industrial valve. The pilot valve is linked with the main valve to work, with higher control accuracy and stronger pressure bearing capacity. It can be adapted to high-pressure pipelines, large reservoirs, industrial liquid storage tanks and other large equipment, and can realize accurate liquid level control of large-flow media.

Compared with solenoid valve, electric liquid level valve and other electric control valves, the float valve has irreplaceable application advantages. First, it is safe, stable and widely applicable, with pure mechanical structure free from electric power failure, and can operate stably in wet, outdoor and non-powered environment for a long time; Secondly, it is energy-saving and maintenance-free, without electric drive and energy consumption, with strong durability of parts and components. It can work stably for a long time under normal conditions, greatly reducing operation and maintenance costs; Thirdly, it has accurate control and good anti-overflow effect. The length of the valve stem can be adjusted according to the height of the equipment, and the liquid level can be flexibly set. The sealing performance after closing is excellent, completely eliminating the overflow and water waste caused by high liquid level; Fourth, it has high cost performance, low equipment procurement cost, simple installation and low failure rate, and is suitable for most of the atmospheric and low-pressure fluid control scenarios.

With the core characteristics of energy saving, high stability and low cost, the ball float valve is always the basic and preferred equipment in the field of liquid level automatic control, playing an important role in water saving, energy saving, automatic operation and maintenance, stable operation of the system, etc.
