A silent and environmentally friendly non-negative pressure water supply equipment

Abstract

The invention relates to the technical field of water supply equipment, and discloses a silent, environment-friendly and non-negative pressure water supply equipment, which includes a device casing, a sound insulation layer is fixedly installed on the inner wall of the device casing, and a water collection tank is fixedly installed in the inner cavity of the device casing , a steady flow tank, an overflow water recovery tank, and a water delivery pipe is fixedly installed on the top of the left side of the water collection tank. The silent and environmentally friendly non-negative pressure water supply equipment connects the first branch pipe through the water supply pipe. When the water pump on the first branch pipe is started, the water in the water collection tank will enter the first branch pipe through the water supply pipe, and then From the top of the water collection tank back to the inner cavity of the water collection tank, it can circulate infinitely, so as to ensure the freshness of the water in the water collection tank. The overflow water recovery tank is directly connected with the water collection tank through the return pipe, and under the action of the water pump , the water collected in the overflow water recovery tank can be returned to the water collection tank for reuse, saving water resources.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a quiet, environment-friendly and 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 superimposed on the residual pressure of the municipal pipe network to supply water 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 Secondary pressurized water supply equipment that is higher than the pressure demand of the direct supply area of ​​the community, generally not less than 1.2Kg). Non-negative pressure water supply equipment is also called pipe network superimposed water supply equipment. The core of pipe network superimposed (no negative pressure) water supply equipment is how to prevent negat...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a silent and environment-friendly non-negative pressure water supply equipment, which has the advantages of keeping the water in the water tank in a flowing state and keeping the freshness of the drinking water, and solves the problem of the existing box-type non-negative pressure water supply equipment. Negative pressure water supply equipment, when the water in the water tank is not being used, it is stored in the water tank for a long time, because the water in the water tank does not keep flowing all the time, which reduces the freshness of the water, and even deteriorates and becomes undrinkable question
