Description

Technical Field

[0001] The utility model relates to the technical field of heat network control, in particular to a heat network balancing control valve which is easy to fix. Background Art

[0002] A heat network balancing valve is a valve that achieves dynamic balance within a heat network system. Its function is to adjust water flow rate and pressure based on the heat consumption of different areas, thereby achieving a balanced distribution of heat energy. Prior art utility model patent application number 202410075450.0 discloses a heat network balancing control valve with flow, pressure, and temperature monitoring and regulation. The valve primarily consists of a housing, flanges, a flow detection assembly, a piston assembly, and a pressure sensor. During installation, the control valve body is simply mounted on the pipeline via flanges at both ends. The inventors believe that this valve presents the following problems during use: Because the control valve is equipped with numerous pressure sensors, flow detection assemblies, and piston assemblies, it is relatively heavy. When installed directly on the heat network pipeline, the pipeline is subjected to the weight of the control valve for extended periods of time. This can easily cause the pipeline to deform after prolonged use, leading to leakage between the pipeline and the control valve. This makes the valve inconvenient to use and has poor reliability.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0020] Example 1

[0021] like Figures 1 to 6The heat network balancing control valve of the present invention includes a balancing control valve body 1, a supporting mechanism and a filtering mechanism. The left and right parts of the balancing control valve body 1 are respectively provided with an inlet pipe 2 and a drain pipe 3. The inlet pipe 2 and the drain pipe 3 are both provided with connecting flanges. The balancing control valve body 1 is provided with a supporting mechanism. The supporting mechanism is used to support and fix the balancing control valve body 1. The filtering mechanism is installed on the inlet pipe 2. The filtering mechanism has a filtering function. When in use, the left and right parts of the balancing control valve body 1 are installed on the pipeline of the heat network through the connecting flanges, so that the inlet pipe 2 is located at the water inlet pipe of the pipeline, and the drain pipe 3 is located at the drain pipe of the pipeline, and the balancing control valve body 1 is supported and fixed by the supporting mechanism. Since the balancing control valve body 1 supports the weight of the balancing control valve body 1 through the supporting mechanism when in use, the supporting force of the balancing control valve body 1 on the heat network pipeline is reduced, and the risk of deformation of the heat network pipeline during use is reduced. It is easy to use and has high reliability and practicality.

[0022] like Figure 1 and Figure 3 The filtering mechanism includes a filter element 5 and two sets of retaining rings 4. The two sets of retaining rings 4 are fixedly installed in the water inlet pipe 2. The filter element 5 is placed in the water inlet pipe 2. The filter element 5 is located between the two sets of retaining rings 4. The filter element 5 is provided with multiple groups of filter holes connected to the left and right. When in use, the water in the pipeline is filtered by the filter element 5 in the water inlet pipe 2 and then enters the balancing control valve body 1. The filtration of the water by the filter element 5 prevents solid impurities in the water from entering the balancing control valve body 1 and causing blockage. It is easy to use and has high reliability.

[0023] like Figure 1 The water inlet pipe 2 is provided with an opening, and a sealing cover 6 is installed at the opening of the water inlet pipe 2 by means of bolts. The sealing cover 6 is used to seal the opening of the water inlet pipe 2. The opening is located above the filter element 5, and a handle 7 is installed on the sealing cover 6. When the filter element 5 needs to be replaced or cleaned, the sealing cover 6 is opened, the filter element 5 is taken out of the water inlet pipe 2, and then replaced or cleaned. This facilitates the handling of the filter element 5.

[0024] like Figure 4 The supporting mechanism includes a base 8, a seat 9 and two sets of connecting components. The base 8 is fixedly installed at the lower end of the balancing control valve body 1, and the base 8 is connected to the seat 9 through two sets of connecting components. When installed, the seat 9 is in contact with the ground, so that the weight of the balancing control valve body 1 is transferred to the seat 9 through the base 8 and the connecting components, reducing the stress of the balancing control valve body 1 on the heat network pipeline.

[0025] like Figure 5The connecting assembly includes multiple sets of fixing assemblies, multiple sets of connecting blocks 10 and multiple sets of positioning blocks 11. The upper ends of the multiple sets of connecting blocks 10 are all provided with positioning blocks 11, and the lower ends of the multiple sets of connecting blocks 10 are all provided with positioning grooves used in conjunction with the positioning blocks 11. The upper end of the base 9 is provided with a positioning block 11, and the lower end of the base 8 is provided with a positioning groove. The two adjacent sets of connecting blocks 10 are connected and fixed by the fixing assembly, and the fixing assembly is a detachable structure. During installation, the appropriate number of connecting blocks 10 are selected according to the installation height of the balanced control valve body 1, so that when the multiple sets of connecting blocks 10 and the base 8 support the balanced control valve body 1, the height of the balanced control valve body 1 is just at a suitable installation height. When assembling the multiple sets of connecting blocks 10, the positioning blocks 11 on the upper side of the connecting blocks 10 are inserted into the positioning grooves at the lower ends of the connecting blocks 10 adjacent to their upper ends, and then the two adjacent sets of connecting blocks 10 are fixed by the fixing assembly. The installation height of the balanced control valve body 1 can be adjusted by adjusting the number of connecting blocks 10, which facilitates the installation and fixation of the balanced control valve body 1.

[0026] like Figure 6 The fixing assembly includes a connecting plate 12 and two groups of fastening bolts 13. The multiple groups of connecting blocks 10 are all provided with threaded holes, and the connecting plate 12 is provided with two groups of through holes. The two groups of fastening bolts 13 pass through the through holes of the two groups of connecting plates 12 respectively and are screwed into the threaded holes on the two adjacent groups of connecting blocks 10. Through the above arrangement, the connecting plate 12 is squeezed and fixed on the two adjacent groups of connecting blocks 10 by the two groups of fastening bolts 13, thereby improving the firmness of the connection between the two adjacent groups of connecting blocks 10.
