Buried non-negative pressure water supply equipment
By designing an underground negative pressure-free water supply system, the pressurized water supply unit is enclosed in an isolation enclosure, which solves the problems of equipment occupying indoor space and electrical components being easily damaged. This achieves space utilization and equipment protection, and extends the service life.

Abstract
An underground non-negative pressure water supply device comprises a pressurized water supply unit which is covered with an isolation hood. The lower end face of the isolation cover is provided with a dismounting port communicated with the internal space of the isolation cover. The lower end face of the isolation cover is provided with a seat plate attached to the isolation cover, and the seat plate shields and seals the disassembly and assembly opening. The pressurized water supply unit is arranged on the upper surface of the seat plate; the seat plate and the lower end of the isolation cover are fixed through a fixing structure; the outer wall of the isolation cover is provided with a plurality of pipe guiding holes communicated with the inner space of the isolation cover. A sealing ring matched with the guide pipe hole is arranged in the guide pipe hole; and an inner sealing part attached to the inner wall of the isolation cover is arranged on the outer peripheral surface of the inner end of the sealing ring. The buried non-negative pressure water supply equipment not only can effectively prevent indoor space from being occupied, but also can guarantee that electrical elements are not damaged, and therefore the service life is effectively guaranteed.
