The device comprises a bottom plate, a base is detachably connected to the upper end of the bottom plate, a machine body is mounted on the upper end of the base, the upper end of the bottom plate is detachably connected with a protection cover, the machine body and the base are located in the protection cover, an adjusting mechanism is mounted on the top in the protection cover, two sliding plates are arranged on the adjusting mechanism, first openings are formed in the two sides of the protection cover, pushing mechanisms are arranged on the sliding plates, the two sliding plates correspond to the two first openings, a worker can conveniently carry out overhauling and maintaining on the machine body, the service life can be prolonged, when the device is not used, the machine body can be thoroughly isolated from the exterior, foreign matter can be prevented from entering in the machine body during storage, transportand mounting, water pollution is avoided, the water supply quality is ensured, health of a drinker can be facilitated, meanwhile, adjusting is facilitated, rapid connection with an external water pipecan be facilitated, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a non-negative pressure water supply equipment. Background technique [0002] The non-negative pressure water supply equipment is a pressurized water supply unit, which is directly connected to the municipal water supply pipe network, and is stacked in series on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (the set pressure must be Higher than the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg) secondary pressurized water supply equipment. [0003] The core of the pipe network stacking (no negative pressure) water supply equipment is how to prevent negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of the unit operation on the municipal pipe ...
