Description

Tank type laminated water supply equipment

technical field

The utility model relates to a tap water supply device, in particular to a tank type stacked water supply device.

Background technique

In the prior art, in order to meet the needs of people's domestic water, a water storage tank or a water tank is generally used to store water, and the water pump is used to pressurize and supply water to users, so that no negative pressure will be exerted on the municipal pipe network. However, this water supply method seriously pollutes water, cannot guarantee the complete circulation of water, cannot utilize the original pressure of the municipal pipe network, and wastes energy.

In order to solve the above problems, the water storage equipment is omitted, and the water supply method is adopted to directly connect the water pump with the municipal pipe network and the user, and the water supply is controlled by frequency conversion.

However, this water supply method will not only have a negative pressure impact on the municipal pipe network. When the water supply of the municipal pipe network is insufficient, the water pump will stop, causing the user to cut off the water, seriously affecting the user's water use, causing water shortage in the water supply pipe, causing pipe wall corrosion and pollute water sources.

Contents of the invention

The technical effect that the utility model can reach is:

The utility model does not generate negative pressure during operation, and can superimpose the required pressure on the basis of the pressure of the municipal pipe network on the premise of ensuring that no negative pressure is exerted on the municipal pipe network to supply water to the user pipe network. When the network pressure is lower than the protection value, the municipal pipe network will automatically perform flow compensation to ensure continuous water supply to users. It can also stabilize the pressure of the user pipe network and eliminate the phenomenon of frequent start-up of water pumps to achieve the purpose of energy saving.

The utility model eliminates the negative pressure influence of only connecting water supply equipment on the water supply pipeline to the municipal pipe network, and the superimposed water supply not only saves energy but also improves efficiency, and is a real non-negative pressure superimposed water supply technology.

In practical application, a protection value is set for the municipal tap water pipe network 1. This protection value is the critical value that may generate negative pressure on the pipe network when the pressure of the municipal tap water pipe network 1 drops and the incoming water is less than the water demand. This value is monitored by pressure sensor 2.

When the control system receives the signal that the pressure of the municipal tap water pipe network 1 from the pressure sensor 2 is lower than the protection value, or the negative pressure threshold signal sent by the negative pressure monitor 18, the steady flow compensator 9 is automatically opened, according to the system It is necessary to carry out steady flow compensation, and make up as much as the difference. In addition, when negative pressure occurs, the water in the regulation area 6 in the sub-chamber steady flow compensation tank 4 flows to the water supply area 5, and compensates the water supply to the user's pipe network to prevent the generation of negative pressure.

On the basis of the pressure of the municipal tap water pipe network 1, superimpose the pressure water supply according to the user's needs, and make up according to the difference The principle of how much to pressurize and save energy.
