Technical Field
[0001] The utility model relates to the technical field of water inlet pipeline monitoring, in particular to a novel non-negative pressure secondary water supply water inlet pipeline monitoring device. Background Art
[0002] In traditional non-negative pressure and secondary water supply, the water inlet pipe uses an ordinary pressure gauge to display the water inlet pressure. When the water pump is working, there is no automatic monitoring of pressure fluctuations in the water inlet pipe in a timely manner.
[0003] The defect of the traditional water inlet pipeline is that when working for a long time, if the pressure of the water inlet pipeline (water tank) fluctuates greatly or even runs out of water, the water pump unit does not receive the shutdown signal in time, and the water pump is still running without water, which will cause damage to the water pump and affect the water quality. In order to cope with the non-negative pressure and secondary water supply inlet pipeline monitoring, the operation is safer and more reliable, so we need a new type of non-negative pressure secondary water supply inlet pipeline monitoring device.
