Abstract
The utility model discloses a water flow differential pressure type control switch which comprises a casing. An upper opening and a lower opening are arranged on the casing, the upper opening is communicated with a water inlet pipe of a water using device, the lower opening is communicated with a water outlet pipe of the water using device, a magnet capable of downward moving under water differential pressure is arranged in the casing, a pressure spring abuts against the bottom end of the magnet, and a riveting ring for shielding a magnetic field of the magnet is fixed on the casing. A magnetically controlled switch for controlling opening and closing of the water using device is further fixed on the casing and located under the riveting ring, and the magnet downward moves to penetrate through the riveting ring and then acts on the magnetically controlled switch. The water flow differential pressure type control switch only detects pressure difference of the water inlet end and the water outlet end of a water heater, doe not influence pipeline pressure, is not influenced by water quality and water flows and overcomes the disadvantages of a water flow switch.
