Description

Water inlet intelligent stacking device

technical field

The invention relates to water transmission and distribution equipment for municipal public secondary water supply water tanks, in particular to an intelligent water-inlet superimposing device for reducing energy consumption of water intake from the water tanks of secondary water supply equipment.

Background technique

At present, the tap water supply system is directly superimposed in the central urban area of the city, and the diameter of the construction of the urban tap water pipe network is insufficient. The water tank is used to buffer the zero-pressure and pressure-shifted water supply, resulting in high energy consumption for equipment operation. At the same time, due to the use of non-negative pressure secondary water supply equipment without water tanks, the pressure drop of the municipal pipe network caused by the abnormally short-term water stoppage of the municipal pipe network and the heavy load of the municipal pipe network during the peak hours of the secondary water supply process caused by direct water intake, The problem of insufficient water supply pressure for atmospheric water supply users is caused. Therefore, the problems of high pressure in the municipal water supply system and high energy consumption of secondary water supply equipment for 24-hour water tanks during peak water consumption by residents need to be solved urgently.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned defects and deficiencies, and provide a water inlet intelligent stacking device that reduces the pressure of the municipal water supply system during the peak water consumption of residents and saves energy consumption for water intake from the water tank.

In order to achieve the above object, the water inlet intelligent stacking device designed by the present invention includes a municipal tap water inlet pipe, a water pump group inlet water collection pipe, and a water pump group. A pressure sensor in front of the pipe, a fully automatic electric valve and a water outlet flow sensor. A branch pipe is arranged on the pipeline between the fully automatic electric valve and the water outlet flow sensor. The branch pipe is connected to the water inlet pipe of the water tank. A water tank water inlet check valve is arranged on the pipeline between them.

In the above technical solution: the municipal tap water inlet pipe (1) and the water tank inlet pipe provide dynamic water supply.

In the above technical solution: an intelligent control cabinet is also included, and the intelligent control cabinet is connected to the water pump set instrument.

The invention realizes unnecessary waste of energy by automatically adjusting the water in the water tank and the water supply of the municipal tap water supply pump group; compared with the traditional equipment, the energy saving of about 20% is realized by taking water from the water tank.

The present invention realizes the intelligent control of the water intake of the water pump group through a fully automatic electric valve and shut-off valve combined with flow detection and pressure detection, aiming at the shortcomings and deficiencies of the traditional water supply equipment equipped with domestic water tanks and complete sets of non-negative pressure secondary water supply equipment. During the secondary water supply process, through the system water inlet pressure and water outlet dynamic flow detection, the water pump inlet mode is automatically controlled; in mode 1, when the water outlet flow of the equipment is greater than the normal flow of the tap water inlet pipe, the system uses the dynamic replenishment of the water tank. Mode 2. When the outlet water flow rate of the equipment is less than the normal flow rate of the tap water inlet pipe, the system uses tap water to directly superimpose the water inlet, which solves the problem of insufficient water supply pressure for normal pressure water supply users.

The present invention avoids pollution in the secondary water supply process through equipment outlet water flow detection and municipal pipe network pressure detection. At the same time, it can be directly connected to the municipal tap water pipe network. The core is that the pressure drop and flow rate of the municipal pipe network will not be affected during the entire continuous water supply process. Burden, to ensure that the peak water consumption of the project will not affect the pressure drop of the municipal pipe network and increase the flow burden of the pipe network, which solves the problems of water quality pollution in the central urban area of the city and the inability to use superimposed pressure to supply municipal tap water.

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

The water inlet intelligent stacking device as shown in Figure 1 includes a municipal tap water inlet pipe 1, a water pump group inlet water collection pipe 7, a water pump group, and an intelligent control cabinet, and the front pressure sensor 2 of the municipal tap water pipe is sequentially arranged on the pipe at the water outlet end. , the fully automatic electric valve 3 and the water outlet flow sensor 6, the pipeline between the fully automatic electric valve 3 and the water outlet flow sensor 6 is provided with a branch pipe, the branch pipe is connected to the water tank inlet pipe 4, and the branch pipe is connected to the water tank inlet pipe 4 The pipeline of the tank is provided with a water tank water inlet check valve 5. The intelligent control cabinet is connected to the instrument of the water pump group, the municipal tap water inlet pipe 1 and the water tank inlet pipe 4 for dynamic water supply.

The invention integrates the shortcomings and deficiencies of the traditional water supply equipment equipped with domestic water tanks and secondary water supply equipment without negative pressure, and solves the problem of energy consumption in equipment operation due to insufficient pipe diameters in the construction of urban tap water pipe networks and buffering zero-pressure water supply through water tanks. high question. At the same time, it solves the pressure drop of the municipal pipe network caused by the abnormal short-term water stoppage of the municipal pipe network and the heavy load of the municipal pipe network when the municipal pipe network is overloaded during the secondary water supply process caused by the use of non-negative pressure secondary water supply equipment without a water tank. , resulting in insufficient water supply pressure for atmospheric water supply users. The "water inlet intelligent stacking device" invented by our company can automatically control the water inlet mode of the water pump through the detection of the system inlet water pressure and outlet water dynamic flow during the secondary water supply process. When the flow rate is high, the system uses the water tank to dynamically replenish water. Mode 2: When the outlet water flow rate of the equipment is less than the normal flow rate of the tap water inlet pipe, the system uses tap water to directly superimpose the water inlet.

To solve the problems of water quality pollution in the central urban area of the city and the inability to use superimposed municipal tap water, the company invented the "Intelligent Water Inlet Superimposed Device", which can avoid the pollution of the secondary water supply process through equipment outlet water flow detection and municipal pipe network pressure detection. At the same time It can be directly connected to the municipal water pipe network. The core is that the pressure drop and flow burden of the municipal pipe network will not be affected during the entire continuous water supply process. The "Intelligent Water Inlet Overlapping Device" selects the water tank and the municipal pipe network for dynamic water supply, so as to ensure that the peak water consumption of the project does not affect the pressure drop of the municipal pipe network and increase the flow burden of the pipe network.
