Description

Technical Field

[0001] The present application relates to the technical field of valve devices, and in particular to a valve device having a dynamic balancing valve and a static balancing valve. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief.

[0003] The existing patent with announcement number CN208169534U discloses a flow control valve, including a flow control valve main valve body and a valve stem. A valve seat for threaded connection of the valve stem is provided on the flow control valve main valve body, and a water inlet and a water outlet are provided on the flow control valve main valve body. A valve block for sealing the water outlet is provided at one end of the valve stem extending into the flow control valve main valve body; by rotating the valve stem, the distance between the valve block and the water inlet is controlled, and the water flow entering the flow control valve main valve body is changed, thereby achieving the purpose of regulating the water flow.

[0004] Regarding the above-mentioned related technologies, in the water supply system in actual life, especially the bathroom water supply, it includes a main water supply pipe and several branch water pipes connected in parallel to the main water supply pipe. The existing flow control valve is installed on the branch water pipe. Since the internal flow of the main water supply pipe remains basically unchanged, when a small number of flow valves are opened, the water flow rate is V1. When other flow valves are opened, the flow in the main water pipe is divided, causing V1 to suddenly decrease. Similarly, when a flow valve is closed, V1 suddenly increases, which causes the water consumption for bathing to fluctuate and the water flow rate to vary greatly. Therefore, it needs to be improved.

When the dynamic balancing valve is activated, all branches containing the static balancing valves are closed. Adjusting the water flow between the water distribution pipes will not affect each other due to fluctuations in flow and pressure. When the static balancing valve is activated, increasing the flow of a particular water distribution pipe will correspondingly reduce the flow of other water distribution pipes. By combining the two balancing valves, the dynamic and static balancing valves can be switched to suit different application scenarios, thereby improving the adaptability of the product.

[0015] Preferably, a plurality of friction lines are provided on a surface of the mounting plate on a side away from the connecting rod.

[0016] By adopting the above technical solution, the presence of the friction lines can increase the roughness of the contact between the mounting plate and the wall, increase the static friction between the mounting plate and the wall, and improve the stability of the valve device installed on the wall.

[0017] Preferably, a first switch valve is provided on the first branch, and the first switch valve is used to control the opening and closing of the first branch; a second switch valve is provided on the second branch, and the second switch valve is used to control the opening and closing of the second branch.

[0018] By adopting the above technical solution, the staff can use the first switch valve to independently control the opening and closing of the first branch, and can also use the second switch valve to independently control the opening and closing of the second branch.

[0019] Preferably, the inner walls of the main water pipe and the branch water pipe are coated with an epoxy resin anti-corrosion layer.

[0031] The following will describe the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. The present application can be embodied in many different forms and is not limited to the embodiments described here.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0034] In the description of the embodiments of this application, unless otherwise specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, integration, or mechanical connections. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this application based on specific circumstances.

[0035] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0036] The embodiment of the present application discloses a valve device having a dynamic balancing valve and a static balancing valve. Figure 1The valve device includes a main water pipe 1, several branch water pipes 2, a static balancing valve 3 and a dynamic balancing valve 4. The main water pipe 1 is connected to an external water source, and each branch water pipe 2 is arranged in a vertical direction and parallel to each other. Each branch water pipe 2 is connected to the main water pipe 1 and is arranged in parallel on the main water pipe 1. The main water pipe 1 is used to supply water to each branch water pipe 2. In this embodiment, the main water pipe 1 and the branch water pipe 2 are made of stainless steel. Stainless steel has the characteristics of high strength and rust resistance, which makes the main water pipe 1 and the branch water pipe 2 not easy to rust and damage, and improves the service life. In some embodiments, the inner walls of the main water pipe 1 and the branch water pipe 2 are coated with an epoxy resin anti-corrosion layer. The epoxy resin anti-corrosion layer can improve the corrosion resistance of the inner walls of the main water pipe 1 and the branch water pipe 2, and extend the service life.

[0037] Each water distribution pipe 2 is connected to a first branch 5 and a second branch 6, arranged in parallel. A static balancing valve 3 is connected to the first branch 5. This valve adjusts the flow resistance by varying the gap (opening) between the valve core and the valve seat, thereby regulating flow. A first on-off valve 11 is installed on the first branch 5 to control the opening and closing of the first branch 5, achieving flow regulation.

[0038] The second branch 6 is connected to a dynamic balancing valve 4, suitable for controlling the flow of non-corrosive liquid media such as heating and air conditioning. A one-time adjustment before operation automatically maintains the system flow at the required set value. A second on-off valve 12 is installed on the second branch 6 to control the opening and closing of the second branch 6, achieving independent control of the flow conditions of the first and second branches 5 and 6.

[0039] During use, the main water pipe 1 supplies water to each branch water pipe 2. Since each branch water pipe 2 is equipped with a static balancing valve 3 and a dynamic balancing valve 4, the static balancing valve 3 and the dynamic balancing valve 4 can be switched between each other. When the dynamic balancing valve 4 is enabled, all branches where the static balancing valves 3 are located are in a closed state, and the adjustment of water flow between each branch water pipe 2 will not affect each other due to fluctuations in flow and pressure. When the static balancing valve 3 is enabled, when the flow of a certain branch water pipe 2 is increased, the water flow of other branch water pipes 2 will be reduced accordingly. Through the combination of dual balancing valves, the dynamic balancing valve 4 and the static balancing valve 3 can be switched between each other to adapt to different application scenarios, thereby improving the adaptability of the product.

[0040] Specifically, a regulating valve 7 is also installed on the water distribution pipe 2. The regulating valve 7 is located on the first branch 5 and is used to adjust the volume flow rate through the water distribution pipe 2 so that the user can flexibly set it according to their needs. Furthermore, an observation tube 8 is also provided on the water distribution pipe 2. The observation tube 8 is made of a transparent material, such as glass. The outer surface of the observation tube 8 is provided with a liquid level scale 9, which is arranged along the length of the observation tube 8. A liquid level indicator block (not shown in the figure) is arranged inside the observation tube 8 to rise and fall. When the user turns the regulating valve 7 to set the flow rate value, the liquid level indicator block will rise or fall accordingly. During adjustment, since the transparent observation tube 8 is light-transmissive, the staff can observe the liquid level scale 9 where the liquid level indicator block is located to determine the flow rate value for debugging, thereby improving convenience.

[0041] Combine Figure 2 and Figure 3 In addition, the main water pipe 1 and the water distribution pipe 2 are mounted on an external wall using multiple mounting assemblies 10 to secure the valve assembly. Mounting assemblies 10 include a connecting rod 101, a threaded sleeve 102, and a mounting plate 103. One end of connecting rod 101 is fixedly connected to main water pipe 1. Threaded sleeve 102 is fixedly connected to mounting plate 103 and threadedly connected to the other end of connecting rod 101. The securing of connecting rod 101 and threaded sleeve 102 is achieved through the force of the threaded connection. Mounting plate 103 is secured to the wall using fasteners, such as fastening bolts or screws.

[0042] During installation, first screw one end of the connecting rod 101 onto the threaded sleeve 102. Then, move the entire valve assembly to the wall, place the mounting plate 103 against the wall surface, and securely fasten the mounting plate 103 to the wall using fasteners. In some embodiments, the mounting plate 103 has a plurality of friction patterns (not shown) on the side facing away from the connecting rod 101. These patterns increase the roughness of the contact between the mounting plate 103 and the wall, increasing the static friction between the mounting plate 103 and the wall and improving the stability of the valve assembly against the wall.

[0043] The implementation principle of a valve device with a dynamic balancing valve and a static balancing valve in an embodiment of the present application is as follows: the main water pipe 1 supplies water to each branch water pipe 2, and each branch water pipe 2 is equipped with a static balancing valve 3 and a dynamic balancing valve 4, and the static balancing valve 3 and the dynamic balancing valve 4 can be switched with each other. When the dynamic balancing valve 4 is enabled, all branches where the static balancing valves 3 are located are in a closed state, and the adjustment of the water flow between the branch water pipes 2 will not affect each other due to fluctuations in flow and pressure. When the static balancing valve 3 is enabled, when the flow of a certain branch water pipe 2 is increased, the water flow of other branch water pipes 2 will be reduced accordingly. By combining the two balancing valves, the dynamic balancing valve 4 and the static balancing valve 3 can be switched with each other to adapt to different application scenarios, thereby improving the adaptability of the product.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
