Description

Technical Field

[0001] This invention relates to the field of pipeline water supply equipment technology, and more particularly to a water distributor device for a large flow ball valve. Background Technology

[0002] In current underfloor heating systems, the manifold, as a core distribution component, operates based on a valve regulation mechanism. By controlling the flow rate of heat sources in each branch, and utilizing the rapid conduction of the heat transfer medium (usually hot water), it achieves temperature regulation in specific spaces or multiple areas through a combination of convection and radiation. Existing manifold products primarily consist of core components such as pipes, valve assemblies, and connection ports. They achieve flow control by mechanically adjusting the opening and closing of valves to change the cross-sectional area of ​​the fluid channels, ultimately resulting in temperature regulation.

[0003] However, after long-term market research and feedback from practical applications, existing manifold technologies still have many defects and problems, limiting their further promotion and application: Existing technologies mostly use copper rod processing or casting processes to manufacture manifold pipes and core components. Although copper has certain thermal conductivity, it is very prone to rusting due to environmental humidity, water quality, and other factors in actual use. The rust can cause blockage inside the pipes, affecting fluid flow efficiency. At the same time, the casting process has the problem of low forming precision. When producing multi-branch pipes with more than 5 branches, the pipes are prone to deformation and bending, which severely limits the types and specifications of products and cannot meet the heating needs of large spaces in multiple areas. In addition, copper products are limited by the mechanical properties of the material. Longer pipes have poor bending resistance and are prone to bending and deformation due to external forces during installation and use, affecting the system's sealing performance. Furthermore, the existing product structure is bulky, which not only increases the difficulty of installation but also places higher demands on the installation space, limiting its application in confined spaces or special layout scenarios. As a scarce metal, copper has a high market price, resulting in high material costs for existing water distributor products. At the same time, the copper rod processing and casting process involves multiple processing steps, a long production cycle, and high labor and equipment costs, which further increases the overall production cost of the product and ultimately leads to increased user costs.

[0004] In addition, the existing water distributor has an unreasonable internal flow channel design, resulting in high fluid resistance and low flow rate, which makes it impossible to achieve rapid temperature regulation. Especially in large spaces or low-temperature environments, the heating speed is slow, affecting the user experience. Furthermore, after a certain number of years of use, copper will undergo an oxidation reaction. The oxide layer will fall off and contaminate the heat transfer medium, while also corroding the internal structure of the pipe, seriously affecting the product's service life. Moreover, copper becomes more brittle at low temperatures, posing a risk of breakage and reducing the product's applicability in cold regions.

[0005] Existing products have complex structural designs and cumbersome component connection methods. When malfunctions such as blockages or leaks occur, disassembly and maintenance are difficult and require professional personnel to operate with special tools. This not only increases maintenance costs but also affects the normal operation of the heating system.

[0006] In conclusion, there is an urgent need for a high-flow-rate ball valve distributor device to solve the above problems. Summary of the Invention

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] 1. This invention presents a high-flow-rate ball valve manifold device. By using stainless steel as the core material for the manifold main pipe and distribution pipe, the product's corrosion resistance, wear resistance, and mechanical strength are significantly improved. This effectively avoids problems such as rusting, oxidation, and low-temperature cracking found in existing copper products, significantly extending service life and greatly reducing user replacement costs. Simultaneously, stainless steel has strong environmental adaptability, operating normally under various environmental conditions such as high temperature, low temperature, and humidity, further broadening the product's application range. Using stainless steel as the core material for the manifold main pipe and distribution pipe results in a lower market price than copper, and the integrated high-pressure molding process reduces processing steps, shortens the production cycle, and lowers labor and equipment costs. Compared with existing copper manifolds, production costs are significantly reduced, resulting in a lower product price and improved market competitiveness, while also lowering procurement costs for users. The integrated high-pressure molding process and the design of the first and second reinforcing ribs improve the structural strength and bending resistance of the manifold main pipe. Even longer pipes maintain good straightness and structural stability, avoiding deformation caused by external forces. The valve body and the manifold main pipe are welded together, ensuring the connection strength and sealing performance between components, reducing leakage and improving the product's operational stability.

[0027] 2. The water distributor device for a large-flow ball valve disclosed in this invention features a submerged trough at the connection point between the main flow channel and the branch channel. The submerged trough is located at the top of the branch channel, allowing water flowing towards the branch channel to first enter the submerged trough. This optimizes the flow channel design. The diameter of the submerged trough is larger than that of the branch channel, increasing the overall flow channel diameter. The use of a rounded corner transition and a submerged outlet structure effectively reduces fluid resistance, increases flow rate, and enables rapid and precise adjustment of indoor temperature, improving heating efficiency and enhancing the user experience. Simultaneously, the submerged outlet and optimized flow channel design reduce eddies and impacts during fluid flow, resulting in operating noise ≤35dB, achieving quiet operation and improving indoor environmental comfort.

[0035] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0036] Example 1:

[0037] Please refer to a water distributor device for a high-flow-rate ball valve. Figure 1-6 The system includes a main water distributor 1, with a main channel 14 inside. Several branch pipes 4 are fixedly installed on the main water distributor 1, and branch channels 5 are provided inside each branch pipe 4. The main water distributor 1 and the branch pipes 4 are made of stainless steel and manufactured using an integrated high-pressure molding process. This significantly improves the product's corrosion resistance, wear resistance, and mechanical strength, effectively avoiding problems such as rusting, oxidation, and low-temperature cracking found in existing copper products. This significantly extends the service life and greatly reduces replacement costs for users. Furthermore, stainless steel has strong environmental adaptability and can operate normally under various environmental conditions, including high temperature, low temperature, and humidity, further expanding the product's application range. Using stainless steel as the core material for the main water distributor 1 and branch pipes 4 results in a lower market price than copper, and the integrated high-pressure molding process reduces processing steps, shortens the production cycle, and lowers labor and equipment costs. Compared with existing copper manifolds, production costs are significantly reduced, resulting in a lower product price and improved market competitiveness. This also reduces procurement costs for users. The integrated high-pressure molding process enhances the structural strength and bending resistance of the main manifold 1, ensuring good straightness and structural stability even for longer pipes, thus avoiding deformation caused by external forces.

[0038] like Figure 6 As shown, the main water distributor 1 has a hollow structure with a housing 11. The main water distributor 1 has a through-flow main channel 14 inside, and ports 3 are fixedly installed at both ends of the main channel 14. The main channel 14 of the main water distributor 1 has a through-cavity structure. The core control of the water flow direction follows the principle of unidirectional downstream flow and branch flow. The overall water flow direction is determined by the pipe connection method of the ports 3 at both ends of the main water distributor. A rotatable ball valve 44 is installed inside the water distribution pipe 4. The branch water flow is controlled by the ball valve 44 to control the on / off state and flow rate. The two work together to achieve precise control of the water flow direction of the main water distributor and the branch water flow.

[0039] Among them, the water flow direction of the main water distributor 1 is a manually preset fixed direction, which is directly determined through pipe connection. There are two conventional control methods to adapt to different operating conditions of heating and water supply systems:

[0040] Forward flow control: Connect the water supply pipe to one end port 3 of the main water pipe 1 of the distributor, and connect the return water pipe to the other end port 3 of the main water pipe. The water flows into the main channel 14 from the water supply port 3, flows unidirectionally along the main water pipe axis through the branch channels 5 of all the branch water pipes 4, and finally flows out from the return water port 3, thus achieving fixed direction control of the main water flow in a single axis.

[0041] Reverse flow control: If it is necessary to flush impurities inside the main pipe and clear pipe blockages, the connection relationship between the water supply and return ends and port 3 can be directly reversed, so that the water flows in the opposite direction to the original positive direction through the main flow channel 14. The reverse water flow impact force is used to clean the pipe. After cleaning, the original water flow direction can be restored by resetting.

[0042] like Figure 4 , Figure 6 As shown, several branch channels 5 are connected below the main channel 14. The water flow in the main channel 14 will be diverted to the branch channels 5 below. The direction, on / off state, and flow rate of the water flow in the branch channel are all controlled by the components of the branch pipe 4. A sinking trough 13 is provided at the connection position between the main channel 14 and the branch channel 5. The sinking trough 13 is located at the top of the branch channel 5. The water flow in the main channel 14 flows vertically downward through the sinking trough 13 into the branch channel 5 of the branch pipe 4, and then flows through the ball valve 44 and the ball valve connector 46 in sequence, and finally flows to the external branch pipeline. The overall direction of the branch diversion is main channel 14, sinking trough 13, branch channel 5 to external pipeline, and this direction cannot be changed.

[0043] like Figure 6 As shown, the water distribution pipe 4 includes a valve body 45 and a valve stem 49. The valve body 45 is fixedly installed below the main water distributor 1 and is located outside the diversion channel 5. The valve body 45 and the main water distributor 1 are connected by welding, which ensures the connection strength and sealing performance between the components, reduces the occurrence of water leakage, and improves the operational stability of the product.

[0044] like Figure 4As shown, the top of the valve body 45 is connected to the bottom of the sinking groove 13; the ball valve 44 is installed inside the valve body 45; the ball valve 44 and the valve body 45 are movably connected by the mounting part 43; the ball valve 44 can rotate inside the valve body 45; the valve stem 49 is inserted into the ball valve 44, and the rotation control of the ball valve 44 is realized through the valve stem 49, thereby realizing the opening and closing of the diversion channel 5; a stop sleeve 48 is fixedly installed on one side of the valve body 45; the stop sleeve 48 is hollow, and a first protrusion 481 is provided at the bottom of the stop sleeve 48; the valve stem 49 includes a main shaft 491; the main shaft 491 is rotatably installed inside the stop sleeve 48, and a second sealing ring 492 is installed between the stop sleeve 48 and the main shaft 491; a second protrusion 493 is provided at the end of the main shaft 491 near the ball valve 44. A controller 41 is installed at the end of the main shaft 491 away from the ball valve 44. The controller 41 includes a handle 411, a decorative cover 412, and a screw 413. The screw 413 is located inside the controller 41 and is fixedly installed at the end of the main shaft 491 away from the ball valve 44. The end of the screw 413 away from the main shaft 491 is provided with a decorative cover 412. The handle 411 is wrapped around the outside of the screw 413. The handle 411 cooperates with the stop sleeve 48 to realize the rotation of the ball valve 44.

[0045] When in use, rotating the handle 411 of the controller 41 causes the main shaft 491 of the valve stem 49 to rotate. The second protrusion 493 at the end of the main shaft 491 engages with the groove 441 of the ball valve 44, simultaneously causing the ball valve 44 to rotate within the valve body 45.

[0046] The ball valve 44 through hole is fully aligned with the branch channel 5: the branch water flow is fully open and the flow rate is maximum;

[0047] The ball valve's 44 through-hole is aligned with the 5-part branch channel: the branch water flow is limited, and the flow rate can be steplessly adjusted.

[0048] The ball valve 44 through hole is completely offset from the branch channel 5: the branch water flow is closed, and the main water flow continues to flow only along the main channel 14.

[0049] like Figure 4As shown, the four corners of the bottom of the sinking trough 13 are rounded at 12 arcs to facilitate water flow. Although the exclusive structural design of the distributor does not directly control the water flow direction, it can ensure the flow efficiency under the preset water flow direction, avoid turbulence and liquid accumulation, and indirectly stabilize the water flow direction. The sinking trough 13 is set at the connection between the main channel 14 and the branch channel 5. The four corners of the bottom of the trough are rounded at 12 arcs to avoid the formation of eddies and the accumulation of impurities when the water flow is divided, ensuring that the water flows vertically downward into the branch channel 5 without directional deviation. The diameter of the sinking trough 13 is larger than that of the branch channel 5, increasing the channel diameter and thus achieving an optimized channel design. The use of rounded corners at 12 arcs and the sinking outlet structure effectively reduces fluid resistance, increases flow rate, and enables rapid and precise adjustment of indoor temperature, improving heating efficiency and enhancing the user experience. At the same time, the sinking outlet and optimized channel design reduce eddies and impacts during fluid flow, with operating noise ≤35dB, achieving the quiet operation standard and improving the comfort of the indoor environment.

[0050] like Figure 2 As shown, an air vent valve 2 is fixedly installed on the top of the main water distributor 1. The air vent valve 2 includes an installation pipe 23, which is rotatably mounted on the air vent valve 2. An air vent pipe 22 is fixedly installed on the side wall of the installation pipe 23. The air vent pipe 22 can rotate with the installation pipe 23, thereby allowing the air vent valve to be freely adjusted 360 degrees, eliminating the limitation of installation space and making the application more flexible. A knob 21 is installed on the top of the installation pipe 23, which controls the opening and closing of the air vent valve 2. The air vent valve 2 at the top of the main water distributor is opened and closed by the knob 21 to discharge air from the main water channel 14, avoiding water flow disorder and uneven flow rate caused by air blockage, and ensuring the smoothness of the preset water flow direction.

[0051] like Figure 6 As shown, a first internal thread 451 is provided on the inner wall of the bottom of the valve body 45; a ball valve connector 46 is installed below the valve body 45, and a first external thread 461 is provided on the outer wall of the top of the ball valve connector 46; the first internal thread 451 and the first external thread 461 cooperate to realize the connection between the ball valve connector 46 and the valve body 45, and a first sealing ring 452 is also installed at the connection position between the ball valve connector 46 and the valve body 45 to realize the sealing of the diversion channel 5.

[0052] like Figure 6 As shown, a second external thread 462 is provided on the outer wall of the middle part of the ball valve connector 46, and a nut 42 is connected to the ball valve connector 46 through the second external thread 462; a third external thread 463 is provided on the outer wall of the bottom of the ball valve connector 46, and a retaining ring 47 is provided inside the nut 42, and the retaining ring 47 is connected to the bottom of the ball valve connector 46 through the third external thread 463.

[0053] like Figure 6 As shown, the mounting component 43 is fixedly installed inside the valve body 45 and is rotatably connected to the ball valve 44; the mounting component 43 includes a first valve seat 431 and a second valve seat 432, the first valve seat 431 is disposed on the top of the ball valve 44, and the second valve seat 432 is disposed on the bottom of the ball valve 44.

[0054] like Figure 6 As shown, a groove 441 is provided on one side of the ball valve 44, and the groove 441 cooperates with the second protrusion 493, with the second protrusion 493 inserted into the groove 441.

[0055] like Figure 1 As shown, a first reinforcing rib 111 is provided on the side wall of the housing 11, and a second reinforcing rib 112 is fixedly installed on the top of the housing 11; the first reinforcing rib 111 and the second reinforcing rib 112 on the side wall of the housing 11 enhance the structural strength of the main pipe, prevent the main pipe of the distributor from being deformed under pressure, thus avoiding the displacement of the main flow channel 14 and ensuring the stability of the axial water flow direction.

[0056] like Figure 1 As shown, port 3 is configured with an octagonal structure, which facilitates disassembly using a universal device and makes maintenance convenient.

[0057] The working principle of this invention is as follows: A rotational torque is applied through the handle 411, causing the handle 411 to rotate the main shaft 491 of the valve stem 49. The valve stem 49 drives the ball valve 44 to rotate within the valve body 45, changing the relative position between the ball valve 44 and the mounting component 43, thereby controlling the opening and closing degree of the branch channel 5 within the valve body 45. When the branch channel 5 is fully open, the heat source fluid enters the sink trough 13 from the main channel 14, then flows into the branch pipe 4, and through the ball valves 44 and ball valve connectors 46 of each branch, flows into the branch pipes for indoor heating. The heated fluid flows into the collection pipe through the branch pipes and finally exits from the outlet pipe, completing the heat cycle. During operation, by adjusting the rotation angle of the handles 411 of each branch, the fluid flow rate of each branch can be precisely controlled, achieving balanced temperature regulation in each area. The air vent 2 discharges air from the system in real time, ensuring smooth fluid flow. The sink trough 13 and the optimized flow channel design reduce fluid resistance and operating noise, improving heating efficiency and user experience.
