Technical Field
The utility model relates to an automatic suppression of electronic type running water inlet channel negative pressure and protection device.
Background
Currently, as the number of users of tap water increases, various pressurized water supply apparatuses are installed on tap water network branches. In the past, negative pressure prevention control of the equipment mainly depends on a negative pressure-free function of a user equipment end, and once the negative pressure-free function of the water supply equipment fails or the water supply equipment does not have the negative pressure-preventing function, great potential safety hazards can be caused to a pipe network. In addition, when the tap water pipe network is stopped due to the overhaul or the fault of the water plant equipment, the pressure of the branch pipe is higher than that of the pipe network due to the reduction of the pressure of the pipe network, so that the tap water flows backwards. In the past, a backflow preventer or a check valve is installed in a user branch pipe to prevent backflow of tap water. However, the check valve of the backflow preventer may cause resistance to tap water to cause energy loss. For the conditions of pipe burst and leakage of a tap water pipeline, water flow is generally sprayed to burst the ground, or the water flow empties a roadbed to cause collapse, and the like, the situations are obviously developed, and large loss is often caused. At present, methods and means for assisting in discovering and judging the pipe burst leakage condition in real time are lacked.
