Description

Technical Field

[0001] The utility model relates to the technical field of thermal heating, in particular to a floor heating system with a balanced structure. Background Art

[0002] Floor heating is the abbreviation of floor radiation heating. It uses the entire ground as a radiator and evenly heats the ground with a low-temperature heat medium not higher than 60°C. It supplies heat to the indoor room through the ground by radiation and convection heat transfer to achieve the purpose of comfortable heating. Floor heating can be divided into two categories according to the heat medium: water floor heating and electric floor heating. The existing water floor heating is the most common. During use, it not only brings people a good heating experience in the cold winter, but also can achieve energy saving and consumption reduction, which is also of great significance to resource conservation.

[0003] In the practical use of floor heating, some rooms are often hot while others are cold, that is, there is a large temperature difference between the rooms, which brings a bad user experience to people. This is caused by the different lengths of the floor heating pipes during the laying process. Therefore, the floor heating needs to be balanced during user use, and the flow of each branch is adjusted through the water distributor to make the temperature of each room basically consistent. However, the existing balancing operation has no definite basis, and users can only make multiple adjustments based on their feelings. After one adjustment, it often takes 6 to 8 hours of circulation to see the specific effect. The whole process is time-consuming and labor-intensive, which affects people's user experience.

[0004] On the other hand, the existing floor heating system may become clogged during use, which will also affect people's heating experience, so it needs regular flushing and maintenance. When flushing the floor heating, people often rely on basins to collect the flushing water. During the whole flushing process, a large amount of wastewater is generated, which also brings inconvenience to use and adjustment.

[0005] Therefore, a floor heating system that is convenient for balancing and flushing the floor heating during use is a problem that needs to be solved. Utility Model Content

[0008] Furthermore, the flow display instrument is installed behind the branch water inlet valve.

[0010] Furthermore, the bottom of the U-shaped transparent tube is connected to a drain, the drain is connected to a drainage pipe, and a drain valve is installed on the drain.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] Embodiments of the present utility model:

[0021] like Figure 1-2 As shown, in the floor heating system of this embodiment, a water inlet main pipe 1 is provided, a main water inlet valve 11 is installed on the water inlet main pipe 1, the water inlet main pipe 1 is connected to a plurality of water inlet branch pipes 2, a branch water inlet valve 21 is installed on each water inlet branch pipe 2, and a flow display meter 22 is installed on the pipeline behind the branch water inlet valve 21.

[0022] Each water inlet branch pipe 2 corresponds to a water return branch pipe 3 , each water return branch pipe 3 is connected to a water return main pipe 4 , a branch water return valve 31 is installed on each water return branch pipe 3 , and a main water return valve 41 is installed on the water return main pipe 4 .

[0023] One end of the return water main pipe 4 is connected to the sewage pipe 5, the sewage pipe 5 is connected to the U-shaped transparent tube 6, the U-shaped transparent tube 6 is connected to the drainage pipe 7 through the Y-shaped tee 71, wherein a sewage valve 51 is installed on the sewage pipe 5, and the bottom of the U-shaped transparent tube 6 is connected to the drain pipe 8, the drain pipe 8 is connected to the drainage pipe 7 through the T-shaped tee 72, and a drain valve 81 is installed on the drain pipe 8.

[0024] The principle of this utility model is:

[0025] When the utility model is in use, on the one hand, it can realize the rapid adjustment of the floor heating balance, and on the other hand, it can realize the rapid and convenient flushing of the blockage of the floor heating pipeline.

[0026] When adjusting the balance of floor heating, the water flow in each pipe can be observed according to the flow display instrument 22 on each water inlet branch pipe 2. At this time, the opening of the branch water inlet valve 21 on the water inlet branch pipe 2 with a smaller flow rate is ensured to remain unchanged, and the branch water inlet valve 21 on the water inlet branch pipe 2 with a larger flow rate is adjusted to reduce its opening. When the valve opening of the branch water inlet valve 21 is reduced, the flow therein will decrease, and the flow on other corresponding water inlet branch pipes 2 will increase. Finally, the flow on the water inlet branch pipe 2 is basically the same (or the flow of the water inlet branch with a smaller flow rate at the beginning is slightly larger than the flow of the water inlet branch with a larger flow rate at the beginning). After a period of circulation, the temperature in each room of the residents will be basically consistent, thereby improving the user's heating experience.

[0027] When cleaning the clogged floor heating pipes, each branch needs to be flushed in turn. At this time, close the main return valve 41, and close the valves on the other water inlet branches 2 and the return branch 3. Only one branch is kept connected at a time, and then open the drain valve 51 to flush the pipe. During the flushing process, the state of the flushing water can be observed through the U-shaped transparent tube 6. When the flushing water becomes clean, the branch can be closed, and then the other pipe can be flushed until all branches are flushed.

[0028] After flushing is completed, a small amount of water will be temporarily stored in the U-shaped transparent tube 6. At this time, the drain valve 81 can be opened to drain the water in the U-shaped transparent tube 6 to avoid the pipeline being filled with water for a long time.

[0029] In the utility model, the flushing water of the pipeline will be discharged directly through the drainage pipe 7, avoiding the traditional phenomenon of manually collecting the water with a basin, making it more convenient and easy to use. At the same time, a Y-shaped tee 71 is used at the connection between the U-shaped transparent tube 6 and the drainage pipe 7 to effectively ensure the rapid circulation of flushing water and make it more stable to use.

[0030] The present invention involves the connection of various pipelines and valves. In actual engineering, reasonable selection can be made according to actual needs and pipeline materials to ensure that the connection is sealed. For example, the U-shaped transparent tube 6 can be made of PVC (polyvinyl chloride) material, and when connected to other pipelines, it can be welded, and the Y-shaped tee 71 can be installed in the drainage pipe 7 (i.e., the sewer pipe, which can discharge sewage into the municipal sewage network) through a flange, etc. It is not difficult for technical personnel in this field to understand and implement it, so it will not be repeated.
