Description

Technical Field

[0001] This application relates to the field of valves, and in particular to a manual valve core distributor. Background Technology

[0002] Manual valve manifolds are fluid control devices widely used in piping systems such as heating and water supply. By installing manually operated valves on each branch, users can manually control the opening and closing of each branch and the flow distribution according to their needs, thereby achieving independent regulation of the medium supply to different areas or terminal equipment.

[0003] In the existing technology, manual valve manifolds generally use solid copper rods to make the pipe body through machining, and install manual valve cores on each branch to achieve flow control. The reason for using copper rods as the main material is that copper has good ductility and machinability, which makes it easy to achieve precision forming of complex structures through machining processes such as turning, drilling, and tapping. At the same time, copper has good pressure resistance and sealing adaptability at room temperature, and has long been regarded as the preferred material for manifold manufacturing.

[0004] However, this type of copper manifold has many drawbacks in practical applications: First, the processing of solid copper rods results in serious material waste (a large amount of copper is cut away) and complicated procedures, leading to high manufacturing costs and long production cycles; second, the surface of copper is prone to oxidation and corrosion, and its toughness decreases in low-temperature environments, making it prone to brittle cracking and leakage, which greatly limits its service life; third, the high thermal conductivity of copper causes heat to be quickly lost through the pipes in the heating system, resulting in serious energy waste; in addition, due to the limitations of the specifications of the copper rod raw materials and machining processes, it is difficult to flexibly produce multi-branch and long-specification products, which cannot fully adapt to the diverse application scenarios.

[0017] Furthermore, a limiting ring groove is formed in the valve body, the limiting ring groove is formed above the internal thread of the valve body, and a limiting ring is provided in the limiting ring groove. The limiting ring is made of elastic metal material and is engaged in the limiting ring groove. The end of the limiting ring has an opening for removing the limiting ring from the limiting ring groove.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0035] Please see Figure 1-2 This application provides a technical solution: a manual valve core 602 water distributor, including a pipe body 1, an inlet 2, an outlet 3, a water flow channel 4, a branch assembly 5, and an adjustment assembly 6. A water flow channel 4 with an inlet 2 and an outlet 3 is formed inside the pipe body 1. The inlet 2 and the outlet 3 are located at both ends of the pipe body 1, and at least one set of branch assembly 5 and adjustment assembly 6 are installed on the pipe body 1.

[0036] Branch component 5 is connected to pipe body 1 by welding, and has a through hole in the center of its interior to guide the water flow in pipe body 1 to the branch.

[0037] Adjustment component 6 is connected to pipe body 1 by welding and is used to control the opening and closing state of branch component 5 and the amount of water flow.

[0038] The main body of pipe 1, branch assembly 5 and regulating assembly 6 is made of stainless steel sheet.

[0039] In this invention, the inlet 2 and the outlet 3 are located at both ends of the pipe body 1 and are on the same axis. The inlet 2 and the outlet 3 are installed inside the pipe body 1 and are connected to the pipe body 1 by welding.

[0040] Please see Figure 3 In this invention, the inlet 2 and outlet 3 are provided with internal threads to facilitate quick threaded connection with the main water inlet pipe.

[0041] In this invention, the adjusting component 6 is located on the upper side of the pipe body 1, and the branch component 5 is located on the lower side of the pipe body 1. Each branch component 5 corresponds to one adjusting component 6 on the same axis. This coaxial layout allows the user to intuitively identify the corresponding branch when manually operating the adjusting component 6.

[0042] Please see Figure 4-5 In this invention, the branch assembly 5 includes an adapter connector 501, an adapter body 502, and a first sealing ring 503. The adapter connector 501 is inserted into the pipe body 1 and connected to the pipe body 1 by welding. The adapter body 502 is inserted into the adapter connector 501 and connected to the adapter connector 501 by welding. Two first sealing rings 503 are fixed on the adapter body 502, one of which is located at the connection between the adapter connector 501 and the adapter body 502, and the other is located at the lower end of the adapter body 502. When assembling the branch assembly 5, the adapter connector 501 is welded to the pipe body 1, and then the adapter body 502 is welded to the adapter connector 501. A first first sealing ring 503 is provided at the connection between the adapter connector 501 and the adapter body 502, and a second first sealing ring 503 is provided at the lower end of the adapter body 502. The double sealing ring structure effectively prevents water leakage from the connection, ensuring the overall sealing performance of the branch assembly 5.

[0043] In this invention, the regulating assembly 6 includes a valve body 601, a manual valve core 602, a handwheel 603, and a second sealing ring 604. The valve body 601 is inserted into the pipe body 1 and connected to the pipe body 1 by welding. The valve body 601 has internal threads. The lower half of the manual valve core 602 is threaded to the center of the valve body 601. The upper end of the manual valve core 602 is inserted into the handwheel 603. The handwheel 603 rotates to drive the manual valve core 602 to rotate. The second sealing ring 604 is fixed inside the valve body 601 and located between the valve body 601 and the manual valve core 602. When assembling the regulating assembly 6, the valve body 601 is welded to the pipe body 1, and the valve body 601 has internal threads. The lower part of the manual valve core 602 is threaded to the inside of the valve body 601, and the second sealing ring 604 is located between the valve body 601 and the manual valve core 602, effectively preventing water leakage from the upper part of the valve body 601. The handwheel 603 is connected to the upper part of the manual valve core 602. When the handwheel 603 is turned to rotate the manual valve core 602 to the closed position, the bottom of the manual valve core 602 is tightly fitted with the outer wall of the hollow channel in the middle of the branch assembly 5 to form a reliable seal and ensure that there is no leakage in the closed state.

[0044] Please see Figure 6-9In this invention, a fastening nut 5011 is provided on the outside of the adapter connector 501. The fastening nut 5011 is connected to the outside of the adapter connector 501 by thread engagement. A retaining ring 5012 is provided between the fastening nut 5011 and the adapter body 502. The retaining ring 5012 is fitted inside the fastening nut 5011. The upper and lower ends of the retaining ring 5012 are chamfered. The inclined surface of the upper chamfer faces the adapter connector 501, and the inclined surface of the lower chamfer faces the fastening nut 5011.

[0045] In this invention, a limiting annular groove 6011 is formed inside the valve body 601, located above the internal thread of the valve body 601. A limiting ring 6012, made of elastic metal material, is provided within the limiting annular groove 6011 and engages with it. The end of the limiting ring 6012 has an opening for removing it from the limiting annular groove 6011. The limiting ring 6012 limits the maximum rotation stroke of the manual valve core 602, preventing excessive rotation by the user from causing the valve core to dislodge or be damaged, thus improving operational safety.

[0046] In this invention, the manual valve core 602 has a sealing gasket 6013 at its bottom, which is fixed to the bottom of the manual valve core 602. When the manual valve core 602 is rotated to the closed position, the sealing gasket 6013 at the bottom of the manual valve core 602 fits tightly against the outer wall of the hollow channel in the middle of the branch assembly 5 to form a reliable seal, ensuring no leakage in the closed state.

[0047] In this invention, the top of the adjustment component 6 is provided with an adjustment mark 7 for indicating the water flow magnitude and opening / closing direction. This indicates the water flow magnitude and opening / closing direction, facilitating intuitive user operation and preventing misoperation.

[0048] In this implementation plan: During assembly, the pipe body 1 is first rolled and welded from stainless steel sheet to form a hollow structure with internal water flow channels 4. Using stainless steel sheet instead of the traditional solid copper rod machining method significantly reduces material waste and processing steps, lowering production costs by more than 50%. Simultaneously, stainless steel has strong corrosion resistance and high surface hardness, extending its service life by more than 45% compared to existing technologies, and also possesses excellent thermal insulation properties, resulting in energy savings of more than 15% over long-term use.

[0049] The inlet 2 and outlet 3 are respectively inserted into both ends of the pipe body 1 and welded to fix them, so that the inlet 2 and outlet 3 are on the same axis. Internal threads are machined on the inside of the inlet 2 and outlet 3 to facilitate quick threaded connection with the main water inlet pipeline.

[0050] Subsequently, adjustment components 6 are welded to the upper side of pipe body 1, and branch components 5 are welded to the lower side of pipe body 1, ensuring that the corresponding adjustment components 6 and branch components 5 are coaxially aligned. This coaxial layout allows users to intuitively align the corresponding branches when manually operating the adjustment components 6.

[0051] When assembling branch assembly 5: The adapter connector 501 is welded to the pipe body 1, and then the adapter body 502 is welded to the adapter connector 501. A first sealing ring 503 is provided at the connection between the adapter connector 501 and the adapter body 502, and a second first sealing ring 503 is provided at the lower end of the adapter body 502. This double sealing ring structure effectively prevents water leakage from the connection, ensuring the overall sealing performance of branch assembly 5. The external thread of the adapter connector 501 is connected to a fastening nut 5011, and a retaining ring 5012 is fitted between the fastening nut 5011 and the adapter body 502. The retaining ring 5012 has chamfers at both ends, with the inclined surface of the upper chamfer facing the adapter connector 501 and the inclined surface of the lower chamfer facing the fastening nut 5011. The retaining ring 5012 generates a contraction force when the fastening nut 5011 is tightened, which evenly engages with the outer wall of the pipe, achieving quick locking and reliable sealing. No sealant is required, which greatly improves installation efficiency and facilitates later maintenance and disassembly.

[0052] When assembling the regulating component 6: The valve body 601 is welded to the pipe body 1, and the valve body 601 has internal threads machined inside. A limiting ring is opened on the inner wall of the valve body 601 above the internal threads, and a limiting ring 6012 made of elastic metal material is engaged in the limiting ring groove 6011. The end of the limiting ring 6012 has a through hole. The limiting ring 6012 is used to limit the maximum rotation stroke of the manual valve core 602, preventing the valve core from being dislodged or damaged due to excessive rotation by the user, thus improving operational safety. The lower part of the manual valve core 602 is connected to the inside of the valve body 601 by threads, and a second sealing ring 604 is set between the valve body 601 and the manual valve core 602 to effectively prevent water leakage from the upper part of the valve body 601. The handwheel 603 is connected to the upper part of the manual valve core 602, and a sealing gasket 6013 is installed at the bottom of the manual valve core 602. When the handwheel 603 is turned to rotate the manual valve core 602 to the closed position, the sealing gasket 6013 at the bottom of the manual valve core 602 fits tightly against the outer wall of the hollow channel in the middle of the branch assembly 5, forming a reliable seal and ensuring no leakage in the closed state. Finally, an adjustment mark 7 is set on the top of the handwheel 603 to indicate the water flow size and opening / closing direction, facilitating intuitive operation by the user and avoiding misoperation.

[0053] When in use, first connect the main water inlet pipe to the internal thread of the water inlet 2 via a threaded connection, and connect the return water pipe to the water outlet 3 to complete the connection between the distributor and the main pipe.

[0054] Branch pipe connection: Insert each branch pipe (such as underfloor heating coil or water supply branch pipe) into the adapter body 502, and then tighten the fastening nut 5011. During the tightening process, the fastening nut 5011 compresses the retaining ring 5012. Under the pressure, the retaining ring 5012 contracts, and its chamfered structure at both ends allows it to evenly grip the outer wall of the pipe, thereby achieving rapid fixation and sealing of the branch pipe.

[0055] Users can determine the current valve's open / closed status and flow direction by observing the adjustment mark 7 on the top of the handwheel 603. When the user rotates the handwheel 603, it drives the manual valve core 602 to rotate synchronously. The manual valve core 602 moves up and down within the valve body 601 through a threaded connection. During the rotation of the manual valve core 602, the second sealing ring 604 maintains a seal between the valve body 601 and the manual valve core 602, preventing water leakage from the upper part of the valve body 601. At the same time, the limit ring 6012 limits the maximum rotation stroke of the manual valve core 602. When the manual valve core 602 is rotated to its limit position, the limit ring 6012 contacts the stepped surface of the manual valve core 602, preventing it from rotating further, effectively preventing the valve core from dislodging and ensuring operational safety.

[0056] When the manual valve core 602 moves downward, its bottom sealing gasket 6013 gradually approaches the branch assembly 5. When the manual valve core 602 is rotated to the closed position, the sealing gasket 6013 at the bottom of the manual valve core 602 fits tightly against the branch assembly 5, cutting off the connection between the water flow channel 4 and the internal through hole of the adapter body 502, thereby achieving complete closure of the branch. When the manual valve core 602 is partially pressed down, the opening degree of the through hole can be adjusted, thereby precisely controlling the water flow in the branch.

[0057] When the manual valve core 602 moves upward, the bottom of the manual valve core 602 disengages from the branch assembly 5, and the water flows through the water flow channel 4 inside the pipe body 1 into the adapter connector 501, and then through the through hole opened in the center of the adapter body 502, and finally flows to the branch pipeline to complete the diversion and transportation.

[0058] The foregoing has provided a detailed description of one embodiment of this application, but the description is merely a preferred embodiment and should not be construed as limiting the scope of this application. All equivalent variations and improvements made within the scope of this application should still fall within the patent coverage of this application.
