Description

Technical Field

[0001] The invention relates to a town heating radiator system Background Art

[0002] With the development of society, winter heating in northern cities of my country is subject to environmental protection requirements, and coal-fired stoves for heating in factories, institutions and houses have long been banned. Pipeline heating and centralized heating have become popular in cities and towns. Most of the water quality in northern my country is poor, and the water contains a lot of sediment particles. The existing radiator adopts the standard of bottom water inlet and bottom water outlet. The upper part of the radiator cavity only produces heat conduction and up and down convection, and does not produce strong turbulence. Sediment particles are easy to adhere to the upper part of the radiator cavity. Over time, they continue to accumulate, resulting in a decrease in heat exchange rate, the upper part of the radiator is not hot, and the indoor temperature is difficult to meet the standard.

[0003] In old urban areas, old cast iron radiators are widely used. This radiator has the advantages of large heat dissipation area, durability, and low cost. However, its disadvantages are heavy weight, poor thermal conductivity, rough inner wall, and easy adhesion of mud and dirt in poor water quality. This radiator is assembled in groups, with a large volume, not easy to disassemble, and even more difficult to clean regularly.

[0004] Because the room temperature is too low, some users illegally discharge hot water from the drain pipe into the sewer, increasing the flow rate of hot water and raising the temperature of the radiator, resulting in a waste of thermal energy resources and water resources. Because the room temperature does not meet the standard, the heating unit is often reported and complained by users, causing tension between users and the heating unit. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a new heating pipeline design structure. The design has the advantages of simple structure, small space occupation, easy installation, low cost, etc. Without increasing the water temperature and water pressure, it can greatly improve the heat exchange rate of the radiator, increase the indoor temperature, and achieve energy saving and environmental protection. The present invention is most suitable for the renovation of old residential areas.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The radiator self-cleaning device is characterized in that: the front side of the radiator is provided with an upper water inlet, a lower water inlet, an upper water inlet pipe, a lower water inlet pipe, and a water inlet three-way reversing valve in sequence, and is connected to the water pipe. The rear side of the radiator is provided with an upper water outlet, a lower water outlet, an upper water outlet pipe, a lower water outlet pipe, and a water outlet three-way reversing valve in sequence, and is connected to the drain pipe. The water flow mode can be changed by adjusting the working positions of the two three-way reversing valves respectively. The inner cavity of the radiator can realize four water flow modes: bottom in, bottom out, top in, top out, top in, bottom out, and bottom in, top out. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 This is a schematic diagram of water flowing from the bottom of the radiator cavity Figure 2This is a schematic diagram of water flowing from the top of the radiator cavity Figure 3 This is a schematic diagram of water flowing in and out of the radiator cavity. Figure 4 This is a schematic diagram of water flowing from the bottom in and out of the radiator cavity.

Adjust the water outlet reversing valve 6, close the upper water outlet pipe 8, and open the lower water outlet pipe 5. The water flows sequentially through the water pipe 1, the water inlet three-way reversing valve 2, the lower water inlet pipe 3, the bottom of the inner cavity of the radiator 9, the lower water outlet pipe 5, the water outlet three-way reversing valve 6, and the drain pipe 7.

Adjust the water outlet three-way reversing valve 6, close the lower water outlet pipe 5, and open the upper water outlet pipe 8. The water flows out through the water pipe 1, the water inlet three-way reversing valve 2, the upper water inlet pipe 4, the top of the inner cavity of the radiator 9, the upper water outlet pipe 8, the water outlet three-way reversing valve 6, and the drain pipe 7 in sequence. The top of the inner cavity of the radiator 9 can be flushed and cleaned, and the gas stored in the inner cavity of the radiator can also be discharged.

[0009] Example 3: If Figure 3 As shown, adjust the water inlet three-way reversing valve 2, close the lower water inlet pipe 3, and open the upper water inlet pipe 4. Adjust the water outlet three-way valve 6, close the upper water outlet pipe 8, and open the lower water outlet pipe 5.
