First, the principle

The valve can be installed at any position in the container. When the liquid in the container increases, the liquid level rises, and when the ball is fully buoyant, the buoyancy is insufficient to drive the permanent magnet control valve to close. When the second ball is subjected to buoyancy, The permanent magnet is driven by the common buoyancy of the two spheres to close the valve; when the liquid in the container drops and the permanent magnet is not affected by the buoyancy of the second sphere, it is still subjected to the buoyancy of the sphere until the liquid surface falls below the *sphere. The permanent magnet is returned to the buoyancy and the valve is opened.

Second, performance

1. It can realize the automatic unmanned duty of various water supply modes, and the electronic water level display outside the water tank.
2. The phenomenon of waterless blow is produced. The realization of the large drop water supply can avoid the occurrence of water hammer and protect the safety of the water tank and the entire water supply pipeline.
3. Achieve a large drop in water supply. The spacing between the * sphere and the second sphere can be adjusted to arbitrarily control the water level drop in the container to improve the water quality in the tank and prevent the production of algae and harmful fungi.
4. The liquid level can be precisely controlled. Adjusting the distance between the * sphere and the permanent magnet can accurately control the height of the water supply level; adjusting the distance between the second ball and the permanent magnet can accurately control the water level in the container.
5. The service life is more than 10 years. Due to the magnetic coupling effect of the permanent magnet, the pressure relief plug is driven to close the valve outside the fully enclosed valve. There is no dynamic seal and no wearing parts. The mechanical life of the valve is up to 200,000 times. It can reduce the huge waste of resources, manpower and material resources caused by the valve replacement.
6. The normal working pressure ranges from 0.1kg to 10kg; it can adapt to the working environment of 1°C----150°C. All materials used have a normal working environment within 150 °C.
7. Easy to install and maintain, no need to modify the water tank structure. The inlet of this type of valve is designed with a union to connect a variety of diameter pipes; the outlet is designed with a one-way check valve and has an anti-siphon function.
8. The pressure resistance is within 16kg. Has been tested by the State Quality Supervision Bureau.
9. energy saving.

Third, the application area

1. Living water tanks, pools.
2. Accurate liquid level control in liquid containers in water conservancy, construction, fire protection, electric power, petroleum, chemical, metallurgy, thermal, pharmaceutical and other industries.
