Novel water storage tank

Abstract

The invention relates to a novel water storage tank. A pressure water storage tank comprises a tank body with an inner cavity; the tank body is composed of an upper cover and a lower cover which are connected in a sealing mode; a flexible diaphragm is pressed and fixed between the upper cover and the lower cover, and separates the inner cavity of the tank body into a clean water cavity and an air cavity; and a water inlet and a water outlet of the clean water cavity are communicated with a clean water outlet of a reverse osmosis membrane unit through a pipeline; and the pressure water storage tank is characterized in that: the pipeline communicating the pressure water storage tank and the clean water outlet of the reverse osmosis membrane unit is provided with a pressure limiting component of which the water inlet is communicated with the clean water outlet of the reverse osmosis membrane unit and of which the water outlet is communicated with the water inlet and the water outlet of the clean water cavity. The novel water storage tank has the advantages of avoiding the potential safety hazard to the work of a water purification machine system due to the increase of the water pressure in the water storage tank, reducing the requirements on the material and the pressure bearing design parameters of the prepared pressure water storage tank, and reducing the cost.

Description

technical field [0001] The invention relates to a novel water storage tank. Background technique [0002] With the development of the economy, the situation of water resources has deteriorated in many places. The shortage and pollution of water resources have become more and more serious, and the problem of drinking water safety for urban residents has become prominent. Aiming at the secondary pollution of tap water in cities and the persistent presence of harmful substances in tap water due to source water pollution, more and more household water purifiers with reverse osmosis membrane as the core filter unit have entered thousands of households. The existing household pure water machine uses the reverse osmosis membrane as the core filter unit. After multi-stage pretreatment and pressurization of tap water, it enters the water unit of the pure water machine. The pure water produced can fully meet the domestic drinking needs of developed countries. water standard. [0003...

AI Technical Summary

Problems solved by technology

However, when the high-pressure switch breaks down, it is impossible to effectively control the increase in water pressure in the pressure water storage tank, resulting in the following two problems: 1. With the increase of the water pressure in the pressure water storage tank, the pure water There are potential safety hazards in the work of the machine system; 2. The materials and design parameters of the prepared pressure water storage tank have great requirements for pressure bearing, which leads to high manufacturing cost of the pressure water storage tank
