A. Principle: The valve can be installed in any position in the container, when the liquid in the container is increased and the liquid level is raised, when the first ball is fully buoyant, the permanent magnet can not be driven to control the valve to be closed due to the insufficient buoyancy. When the second When the ball is buoyant, the permanent magnet is driven by the common buoyancy of the two balls to close the valve. When the liquid in the container drops and the permanent magnet is not buoyant by the second ball, the buoyancy of the first ball is still affected until the liquid drop To the first ball below the permanent magnet is not buoyancy effect back to the valve open. B. Performance: 1. To achieve a variety of water supply automatic unmanned, water tank outside the water level control. 2. To achieve large drop water. Can adjust the distance between the first sphere and the second sphere and control the water level drop in the container arbitrarily to improve the water quality inside the water tank and prevent the generation of algae and harmful fungi. 3. No water hammer phenomenon. The realization of big water supply can avoid water hammering phenomenon and protect the water tank and the entire water supply pipeline. 4 life of more than 10 years. Due to the use of the magnetic coupling effect of permanent magnets, the pressure-relief bolts are driven outside the fully-enclosed valve body to control the pressure-tight closing of the valve without any moving seals or wearing parts. The mechanical life of such valves is as high as 200,000 times or more. Can reduce the valve caused by the replacement of resources and manpower, material and great waste. 5. Can accurately control the liquid level. Adjusting the distance between the first sphere and the permanent magnet can precisely control the height of the water supply level. Adjust the distance between the second sphere and the permanent magnet so that the water level in the container can be precisely adjusted. 6. Installation, maintenance is simple, no need to transform the tank structure. This type of valve inlet design of live joints, can be connected to a variety of caliber pipe; outlet design check valve with a one-way, with anti-siphon function. 7. Normal working pressure range 0.1kg-10kg; can adapt to 1 ℃ ---- 150 ℃ working environment. All materials used in the normal working environment are within 150 ℃. 8. Compression capacity of less than 16kg. Has been tested by the State Quality Supervision Bureau. 9. Environmental protection, energy saving. C. Applications: 1. Living water tank, pool. 2. Water, construction, fire, electricity, petroleum, chemical, metallurgical, thermal, pharmaceutical and other industries within the precise liquid level control container.
