The utility model relates to a novel safe and reliable float valve which comprises a valve body, a valve plate for opening and closing an inner cavity is rotatably installed at the position of the inner cavity of the valve body, the valve plate is driven by an opening and closing unit, and the opening and closing unit comprises a double-torsion-spring assembly, a pin shaft, a valve body rubber button and a valve plate rubber button. The valve plate is rotationally installed on the valve body through a pin shaft, one end of the double-torsion-spring assembly is connected with the valve body through a valve body rubber button, and the other end of the double-torsion-spring assembly is connected with the valve plate through a valve plate rubber button. The float valve has the advantages that the torsion and the safety coefficient are increased by improving the opening and closing unit, so that the service life of the whole float valve is prolonged, and the safety and the reliability of the float valve are improv
