Normal-pressure fresh water storage and supply device

Abstract

The invention discloses a normal-pressure fresh water storage and supply device. A pressure bearing water storage tank is connected into an under-pressure tap water pipe network, a water inlet pipe opening, a pollution discharge water draining opening and a reserved water outlet provided with valves are mounted on the bottom of a water storage tank body, a water outlet pipe opening, a pressure meter and a gas supplementing pipe opening with valves are mounted on the top of the water storage tank body, the gas supplementing pipe opening is provided with an electromagnetic valve set, the water inlet pipe opening of the water storage tank body is connected with a water inlet of the under-pressure tap water pipe network, the water outlet pie opening is connected to a supply water using point,a water supply pipeline check valve is mounted between the water outlet pipe opening and the supply water using point, a tank top automatic exhaust valve is mounted between the water outlet pipe opening and the water supply pipeline check valve, and the water outlet pipe opening communicates with the water inlet of the under-pressure tap water pipe network through a bypass pipeline valve, and thereserved water outlet in the bottom of the water storage tank body is connected to the supply water using point sequentially through a pressurizing water pump set and a water outlet closing valve check valve. Along with water supply of the under-pressure water supply pipeline, stored water is updated in time, and direct water using of under-pressure water supply in the supply water using point cannot be affected.

Description

technical field [0001] The invention relates to a fresh water storage and supply equipment group composed of a pressure-bearing stainless steel water storage tank, a pressurized water supply pump group, a linkage electromagnetic valve group and pipeline valves. Background technique [0002] It is unimaginable for people to live without water in their daily living or working. The water supply company pressurizes and supplies domestic water in towns, villages, and even every corner through the pipe network. Water outage is also a common phenomenon in water supply. Short-term water outage will not affect life and work, but it will also cause inconvenience. Long-term water outage will seriously affect life. No matter how long the water outage is, it is necessary to store enough spare The time of water cut-off varies, but the reserved water is stored under normal pressure and in contact with the atmosphere, and the water quality cannot be guaranteed when stored for a long time. ...

Water outage is also a common phenomenon in water supply. Short-term water outage will not affect life and work, but it will also cause inconvenience. Long-term water outage will seriously affect life. No matter how long the water outage is, it is necessary to store enough spare For water, the time of water cut-off varies from time to time, but the reserved water is stored under normal pressure and in contact with the atmosphere, and if it is stored for a long time, the water quality cannot be guaranteed. It has deteriorated when used, which wastes water and cannot meet the use requirements.

In addition, some places have emergency needs, and they also need to reserve a certain amount of water. The timing of use is uncertain, and even long-term storage is required. use

[0003] The current normal-pressure water storage is used to supply water to the water point after the water is cut off. Without the water supply pressure, the water can only be taken by gravity, or the water pump can be used to increase the pressure. Due to the insufficient water filling of the water pump, it cannot be started in time, affecting the water supply, or it can be vented for a long time. Non-use, corrosion and other reasons will affect the water quality, and the water quality cannot be guaranteed, so that the stored water cannot be put into use

Therefore, various problems of water sources and pipe networks will affect the normal water supply and stop the water, affecting the use of water points. In order not to affect the use, it is necessary to store spare water; some special-purpose places need to reserve a certain amount of spare water. The current water storage The method and the way of water intake and supply will affect the quality of the stored water. At the same time, the water supply and intake are also extremely inconvenient, the maintenance is difficult, the equipment is easily damaged, and it is difficult to put it into use in time.
