Description

Technical Field

[0001] The utility model relates to the technical field of heating systems, in particular to a secondary network mixing water pump heating system. Background Art

[0002] At this stage, my country's economic growth is relatively fast. Large-scale commercial buildings have appeared around many old residential areas. These commercial buildings are unevenly distributed and vary in size. In order to meet the heating needs of newly built commercial buildings, some heating companies will renovate the heat exchanger stations. These old heat exchanger stations have limited space and cannot build a new heating unit. At the same time, it also reduces investment. The heating company changed the original secondary network pipeline into two through a water divider and a water collector to separate residential and commercial areas.

[0003] However, after solving the problem of commercial heating, the disadvantages also appeared. The heat demand of these commercial buildings is different from that of residential buildings. There are no people at night, so the heat demand is lower, while the residential buildings need to maintain a constant temperature throughout the day. Therefore, personnel can only be arranged every day to control the temperature by adjusting the commercial valves, which wastes manpower and material resources. At the same time, the temperature setting cannot be accurately controlled, which will lead to heat waste and certain safety hazards. Utility Model Content

[0009] Beneficial Effects

[0010] The utility model provides a secondary network mixed water pump heating system, which has the following beneficial effects:

[0011] 1.

Therefore, the temperature control of commercial heating at night can be automatically controlled, without manually adjusting the commercial valve to control the temperature, which can effectively reduce unnecessary heat loss and play a role in energy saving;

[0012] 2. By arranging a temperature transmitter on the first water supply pipe, the temperature inside the first water supply pipe can be measured.

[0017] In this embodiment, by installing a water supply main 1, high-temperature water for heating flows into the water supply main 1. By installing a water divider 2, the water supply main 1 can be divided into a first water supply pipe 3 and a second water supply pipe 4, so that the water supply main 1 can be divided into two branches. The first water supply pipe 3 is connected to the first radiator 14 to heat the residence, and the second water supply pipe 4 is connected to the second radiator 15 to heat the business. By providing a first return water pipe 7 and a second return water pipe 8, low-temperature water flowing out of the first radiator 14 and the second radiator 15 can enter the first return water pipe 7 and the second return water pipe 8 respectively. 8, the water of the first return water pipe 7 and the second return water pipe 8 can be merged and flowed into the return water main pipe 5 by installing a water collector 6. By connecting a mixing water pipe 13 and arranging a mixing water pump 9 on the mixing water pipe 13, part of the low-temperature water of the return water main pipe 5 can be mixed into the high-temperature water of the second water supply pipe 4, and the mixing flow rate of the low-temperature water can be controlled by frequency conversion of the mixing water pump 9, so that the water supply temperature of the second water supply pipe 4 can be controlled. Therefore, the temperature of commercial heating at night can be automatically controlled without manually adjusting the valve to control the temperature, which can effectively reduce unnecessary heat loss and play a role in energy saving.

[0018] As an embodiment of the present utility model, a check valve 10 is provided on the mixing pipe 13 downstream of the mixing pump 9 .

[0019] In this embodiment, the check valve 10 is provided to prevent a small circulation from occurring when the mixing water pump 9 stops.

[0020] As an embodiment of the present utility model, butterfly valves 11 are provided on the water mixing pipe 13 upstream of the water mixing pump 9 and downstream of the check valve 10 .

[0021] In this embodiment, a butterfly valve 11 is provided and the closing of the butterfly valve 11 is controlled to control whether part of the low-temperature water in the return water main pipe 5 can enter the second water supply pipe 4 for mixing.

[0022] As an embodiment of the present utility model, a temperature transmitter 12 is provided on both the first water supply pipe 3 and the second water supply pipe 4 .

[0023] In this embodiment, by providing a temperature transmitter 12 on the first water supply pipe 3, the temperature inside the first water supply pipe 3 can be measured. By providing a temperature transmitter 12 on the second water supply pipe 4, the temperature inside the second water supply pipe 4 can be measured. Moreover, the temperature variable can be converted into a transmittable standardized output signal and transmitted to an external automatic control device, so as to control the frequency of the mixing water pump 9 to control the mixing flow rate of low-temperature water, and further control the water temperature in the second water supply pipe 4.

[0024] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0025] The working principle and use process of the utility model are as follows: when the heating system is in use, high-temperature water enters the water supply main pipe 1, flows into the first water supply pipe 3 and the second water supply pipe 4 respectively after passing through the water distributor 2, and then enters the first radiator 14 and the second radiator 15, so as to realize heating for commercial and residential areas respectively. The low-temperature water flowing out after passing through the radiator enters the first return water pipe 7 and the second return water pipe 8 respectively. After passing through the collector 6, the water in the first return water pipe 7 and the second return water pipe 8 merges and flows into the return water main pipe 5. When it is necessary to start the mixing water pump 9 system at night, open the two butterfly valves 11 to allow the low-temperature water in the return water main pipe 5 to enter the second water supply pipe 4 through the mixing water pump 9, so that the low-temperature water is mixed with the high-temperature water. The mixing water flow rate is controlled by automatic frequency conversion of the mixing water pump 9, so that the water temperature in the second water supply pipe 4 can be controlled, and the water temperature in the first water supply pipe 3 will not be affected in any way, so that the temperature of commercial heating can be controlled at night without affecting the residential heating temperature.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
