Non-negative pressure water supply device

Abstract

The invention discloses a non-negative pressure water supply device. The non-negative pressure water supply device comprises a front water suction pump, a main water tank, a rear water supply pump, auser main pipe, a sewage discharge structure, a non-negative pressure adjusting device, a plurality of inlet pipes and a water tank fixing frame, wherein a main water inlet pipe and a main water outlet pipe are arranged on the main water tank, a vertical inner pipe and a vertical outer pipe are arranged in the main water tank, the vertical outer pipe is in rotary sealing fit with the vertical inner pipe, and a cleaning opening and a sealing cover are arranged at the top of the main water tank; the non-negative pressure water supply device further comprises a cleaning hard pipe, a cleaning hoseand a cleaning ball valve; the sewage discharge structure comprises a sewage discharge hole, a sewage discharge vertical pipe, a sewage discharge transverse pipe and a sewage discharge ball valve; and the non-negative pressure adjusting device comprises a top air hole, a top air pipe, a filter screen, a main floating block, a main ball connecting rod and a main blocking ball. The non-negative pressure water supply device has the beneficial effects that the water supply pressure of a municipal water supply pipe network can be guaranteed not to be subjected to or less subjected to loss on the premise of allowable conditions, a special structure for a water tank cleaning scene is provided, and a non-stop water tank cleaning function can be realized, so that the water supply capacity can be enhanced and guaranteed, and the water use experience of a user is improved.

Description

technical field [0001] The invention belongs to the technical field of water supply, in particular to a non-negative pressure water supply equipment. Background technique [0002] Non-negative pressure water supply equipment is a device commonly used in the field of water supply for high-rise buildings. It has various forms, and it can protect the water supply pressure of the municipal water supply network to a certain extent from no or less loss. Water tanks (water tanks) also often appear in non-negative pressure water supply equipment, which can stabilize flow and assist regulation. The water tank needs to be cleaned regularly to avoid excessive internal scale and impurities. At present, when cleaning the water tank, it is necessary to stop the water for the user, which causes inconvenience to the user for using water. Contents of the invention [0003] The invention provides a non-negative pressure water supply device, which can ensure that the water supply pressure ...
