Tank-type non-negative-pressure water supply equipment with function of preventing water from overflowing

Abstract

The invention relates to the technical field of waterproofing of tank-type non-negative-pressure water supply equipment, in particular to tank-type non-negative-pressure water supply equipment with the function of preventing water from overflowing. The tank-type non-negative-pressure water supply equipment with the function of preventing the water from overflowing comprises a tank-type non-negative-pressure water supply equipment body, two pairs of first grooves are formed in the inner upper wall face of a sealed water tank of the tank-type non-negative-pressure water supply equipment body and located at the inner edge of a water outlet, first driving frames are installed in the first grooves, first air cylinders are installed on the side wall faces of the first driving frames, first support plates are fixed to the driving ends of the first air cylinders, second grooves are formed in the side wall faces of the first support plates, second driving support frames are fixed in the second grooves, and first swinging motors are installed on the side wall faces of the second driving support frames. The tank-type non-negative-pressure water supply equipment with the function of preventing the water from overflowing is novel in structure and convenient to operate, and effectively helps people to block a water inlet and the water outlet of the sealed water tank of the tank-type non-negative-pressure water supply equipment body, a large amount of water in the sealed water tank during maintenance is prevented from overflowing, the waste of water resources is prevented, and at the same time, a large amount of suspended solids in water can be adsorbed.

Description

technical field [0001] The invention relates to the technical field of waterproofing of tank-type non-negative pressure water supply equipment, in particular to a tank-type non-negative pressure water supply equipment with the function of waterproofing and overflowing. Background technique [0002] The non-negative pressure water supply equipment is a kind of pressurized water supply unit directly connected with the municipal water supply pipe network, on the basis of the residual pressure of the municipal pipe network to provide superimposed water supply in series to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (the set pressure must be high Secondary pressurized water supply equipment for the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg). [0003] Nowadays, the secondary water supply guarantees people's daily life, but the non-negative pressure water supply equipment will ...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, the secondary water supply guarantees people's daily life, but the non-negative pressure water supply equipment will be worn out after long-term use. During work, it is easy to lose water at the water inlet or outlet due to long-term disrepair or other external reasons, so that the water will overflow. It will waste water resources, so maintenance is required. During maintenance, because the closed water tank contains a large amount of water, it cannot be discharged, which will lead to the failure of maintenance work. At the same time, the closed water tank needs to be cleaned regularly to ensure water quality safety. In view of this, In view of the above-mentioned problems, this case was produced
