Double ball type large drop permanent magnet liquid level automatic control valve

XNUMX. Principle

　　The valve can be installed at any position in the container. When the liquid in the container increases and the liquid level rises, when the first sphere receives full buoyancy, the permanent magnet control valve cannot be driven to close due to insufficient buoyancy. When the second sphere receives 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 affected by the buoyancy of the first sphere until the liquid level falls to the first Below the sphere, the permanent magnet returns to its position without buoyancy, and the valve opens.

XNUMX. Performance

1. It can realize the automatic unattended operation of various water supply methods, and the electric control water level display outside the water tank.
2. Realize the large drop water supply.The distance between the first sphere and the second sphere can be adjusted, and the water level drop in the container can be arbitrarily controlled to improve the water quality in the water tank and prevent the production of algae and harmful fungi.
3. No water hammer phenomenon occurs.The realization of large-drop water supply can avoid water hammer and protect the safety of the water tank and the entire water supply pipeline.
4. The service life is more than 10 years.Because the magnetic coupling of permanent magnets is used to drive the pressure relief bolt outside the fully enclosed valve body to control the valve to close under pressure, there is no dynamic seal, no vulnerable parts, and the mechanical life of this type of valve is as high as 20 times.It can reduce the great waste of resources, manpower and material resources caused by the replacement of the valve.
5. The position of the liquid level can be precisely controlled.Adjusting the distance between the first ball and the permanent magnet can accurately control the height of the water supply water level; adjusting the distance between the second ball and the permanent magnet can accurately control the water level in the container.
6. Installation and maintenance are simple, and there is no need to modify the water tank structure.The water inlet of this type of valve is designed with a flexible joint, which can be connected to pipes of various diameters; the water outlet is designed with a one-way check valve, which has an anti-siphon function.
7. 正常工作压力范围在0.1kg—10kg；能适应1℃----150℃的工作环境。使用的所有材料的正常工作环境都在150℃以内。
8. Compressive capacity is within 16kg.It has been tested by the National Quality Supervision Bureau.
9. energy saving.

XNUMX. Application areas

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