The inside filtration condition of filter can be directly perceived to see through window Y type strainer valve, if the aquatic particulate matter blocks up the filter screen and can be directly perceived to open the convenient emission of filter valve.
The utility model discloses an among the no negative pressure water supply system of regulation formula, when pressure detection device detected pressure and is 0.35MPa, normal water supply flow is inlet channel → window Y type filter valve → backflow prevention valve → pressure detection device → electric control valve (open wide) → butterfly valve on the inlet channel → regulation balance tank → butterfly valve on the high district outlet conduit → water pump → outlet header pipe. When pressure detection device detects pressure and is 0.15MPa, for preventing that no negative pressure system excess water intaking influences the low zone water use, the electrical control valve aperture closes little or closes, when water header pipe department outlet flow is greater than inlet channel department inlet flow (accessible water pressure size is judged), the vacuum inhibitor on the regulation and storage balancing tank is opened, level sensor plays a role, when the liquid level in the regulation and storage balancing tank to minimum water position (see figure 2), second controlling means control water pump is closed, the shut down. When the pressure detection device on the water inlet pipeline is recovered to 0.35MPa, the electric regulating valve is fully opened, and water is normally supplied.
