Especially under high flow and high water pressure conditions, it can significantly reduce system operating noise and improve user comfort. At the same time, the inclined surface increases the contact area between the valve core and the sealing gasket, so that when the valve core is closed, the force direction of the contact surface between the sealing gasket and the valve seat is more reasonable, the sealing pressure distribution is uniform, and it is not easy to have uneven load or side wear. It is not easy to fail or leak after long-term opening and closing, and the service life of the sealing components is extended.

Description

Technical Field

[0001] This invention relates to the field of pipeline water supply equipment technology, and more particularly to a water distributor device that is easy to control. Background Technology

[0002] Underfloor heating systems have become the mainstream heating method for modern buildings due to their advantages such as uniform heating, high comfort, and energy saving. As the core component of the underfloor heating system, the manifold plays a crucial role in hot water distribution, flow regulation of each branch, and control of system water circulation. Its performance directly affects the heating efficiency, temperature uniformity, and service life of the underfloor heating system.

[0003] Existing underfloor heating manifolds are primarily made of cast copper. Their core technical feature is that the pipe body and various connecting parts are integrally cast. Valves on the valve body regulate the hot water flow in each branch, achieving temperature control for different rooms or areas. As the hot water circulates within the underfloor heating pipes, heat is transferred to the indoor air and surfaces through heat conduction, thus completing the heating process. However, these cast copper manifolds suffer from several intractable technical defects in practical applications, as follows:

[0004] In traditional structures, the control valve and the branch water supply circuit are not inclined, and the water flow turns sharply when entering the branch circuit from the main pipe, which easily forms strong eddies and local resistance, resulting in significant throttling losses and head losses. This leads to small branch flow, low heating circulation efficiency, slow indoor heating, and excessively long temperature control cycles. At the same time, the traditional planar or vertical sealing structure causes the sealing gasket to be subjected to uneven load and severe side wear when the valve core is closed. The uneven distribution of sealing pressure makes it easy for the seal to fail and leak after long-term opening and closing, which greatly shortens the service life of the sealing components.

[0005] In conclusion, there is an urgent need for a water distributor device that is easy to control in order to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a controllable manifold device. It solves the problems of existing manifolds where the control valve and branch lines lack an angle, causing the water flow to abruptly change direction when entering the branch line from the main pipe, easily forming strong eddies and local resistance, resulting in significant throttling losses and head losses. This leads to insufficient branch flow, low heating circulation efficiency, slow indoor temperature rise, and excessively long temperature control cycles. Simultaneously, traditional planar or vertical sealing structures cause uneven stress on the sealing gasket when the valve core is closed, resulting in severe lateral wear and uneven distribution of sealing pressure. This leads to seal failure and leakage after long-term operation, significantly shortening the service life of the sealing components.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a water distributor device that is easy to control, comprising a main water distributor pipe, a control valve installed on one side of the top of the main water distributor pipe, a water distributor branch pipe installed at the bottom of the main water distributor pipe, and an angle between the control valve and the water distributor branch pipe.

[0016] In a preferred embodiment of the present invention, a handwheel is fixedly installed at the end of the valve stem away from the main water distributor.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0028] 1. This invention discloses a controllable manifold device, which features a control valve installed on one side of the top of the main manifold pipe and manifold branches installed at the bottom of the main manifold pipe. An angle is established between the control valve and the manifold branches. In this invention, the control valve and valve core connector are arranged at an inclined angle. Compared to traditional vertical or horizontal straight-through structures, this allows for a smoother transition of water flow from the main manifold pipe into the manifold branches, avoiding eddies and throttling losses caused by sharp bends. The flow path is smoother, head loss is smaller, and the branch flow rate is greater under the same pressure, resulting in higher heating circulation efficiency, faster indoor heating, and a significantly shorter temperature control cycle. The angled flow path also makes the water flow direction gentler. This design reduces vibration and whistling caused by high-speed water flow impacting the pipe wall, especially under high flow and high water pressure conditions. It can significantly reduce system operating noise and improve user comfort. At the same time, the inclined surface increases the contact area between the valve core and the sealing gasket, making the force direction between the sealing gasket and the valve seat more reasonable when the valve core is closed. The sealing pressure distribution is uniform, and it is less prone to uneven load and side wear. It is less likely to fail or leak after long-term opening and closing, thus extending the service life of the seals. In addition, the angle makes the water channel form a natural upward / outward guiding trend, which is conducive to the smooth discharge of water carrying air bubbles. It is less likely to form air pockets in the valve cavity and the root of the branch, avoiding problems such as insufficient heating and poor circulation caused by air blockage.

[0029] 2. The water distributor device presented in this invention is easy to control. By setting the control valve to be tilted, the handwheel is tilted outward, leaving a larger operating clearance between the handwheel and the wall, cabinet and pipe. After installation, there will be no problem that the handwheel is too close to the wall to turn or that tools cannot be inserted. Users can adjust the flow rate and switch the branch circuits easily and effortlessly.

[0030] 3. The water distributor device presented in this invention is easy to control. By using a stainless steel main pipe for integral high-pressure molding, it achieves high pressure resistance, robust structure, lighter weight, and lower cost. The valve body, valve stem, valve core, valve sleeve, valve core connector, adapter, and nut are all made of stainless steel. Compared to copper water distributor devices, this improves the pipe's bending resistance, reduces rust, extends service life, and reduces cost. Furthermore, because stainless steel has a lower density than copper, this device's lightweight design meets the needs of various usage scenarios. Reinforcing ribs are fixedly installed on the main pipe, ensuring high pressure resistance while maintaining an aesthetically pleasing appearance and further enhancing pipe strength, preventing bending and blockage. The integrated high-pressure molding process also ensures high product quality and prevents bending during the production of pipes for 2-12 or more branch lines. Attached Figure Description

[0041] 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.

[0042] Example 1:

[0043] Please refer to an easily controllable water distributor device. Figure 1-9 The system includes a main water distributor 1, a control valve 2 mounted on one side of the top of the main water distributor 1, and a branch water distributor 3 mounted on the bottom of the main water distributor 1. The acute angle between the control valve 2 and the branch water distributor 3 is 30°. The branch water distributor 3 includes a valve core connector 34, and a connecting block 35 is provided at one end of the valve core connector 34 near the control valve 2. The connecting block 35 is inserted into the bottom of the main water distributor 1. The top of the connecting block 35 is inclined, and the inclined surface of the top of the connecting block 35 is perpendicular to the control valve 2, so that the control valve... 2. The valve core connector 34 is arranged at an inclined angle. Compared with the traditional vertical or horizontal straight-through structure, the water flow transitions more smoothly when entering the branch line 3 from the main pipe 1 of the distributor. This avoids eddies and throttling losses caused by sharp bends, resulting in a smoother flow path, less head loss, a larger branch flow rate under the same pressure, higher heating circulation efficiency, faster indoor heating, and a significantly shorter temperature control cycle. The angled flow path makes the water flow turn more gently, reducing the vibration and whistling caused by the high-speed water flow impacting the pipe wall. Especially under high flow and high water pressure conditions, it can significantly reduce system operating noise and improve user comfort.

[0044] like Figure 1 As shown, one end of the main water distributor 1 is equipped with an inlet connector 4, and the other end is equipped with an outlet connector 5.

[0045] like Figure 1 and Figure 4 As shown, the main pipe 1 of the water distributor is provided with a main channel 11; a reinforcing rib 12 is installed on one side of the main channel 11. The reinforcing rib 12 is located between the control valve 2 and the branch pipe 3 of the water distributor. It ensures high pressure resistance and aesthetic appearance, and also further improves the strength of the pipe body, avoiding bending and blockage.

[0046] like Figures 5-6 As shown, the control valve 2 includes a valve stem 23, a valve core 24, a valve body 26, and a valve sleeve 27. The valve sleeve 27 is fixedly installed on one side of the top of the main water distributor 1. The valve body 26 is installed inside the valve sleeve 27. The valve core 24 is fixedly installed inside the valve body 26. The valve stem 23 is fitted inside the valve core 24. A sealing gasket 25 is fixedly installed at one end of the valve stem 23 near the branch water distributor 3. The valve core 24 is moved up and down by the control valves 2 installed on the main water distributor 1 to adjust the water flow and achieve the purpose of temperature control.

[0047] like Figure 5 As shown, the valve sleeve 27 has a second internal thread 271 on the side near the valve stem 23, and the valve body 26 has a second external thread 261 on the side near the valve sleeve 27. A stop block 262 is provided on one side of the second external thread 261. The second internal thread 271 and the second external thread 261 cooperate to allow the valve sleeve 27 to fit onto the valve body 26, and the stop block 262 to abut against the top of the valve sleeve 27. The valve core 24 has a first internal thread 241 on the side near the valve stem 23, and the valve stem 23 has a first external thread 231 on the side near the valve core 24. The first internal thread 241 and the first external thread 231 cooperate to allow the valve stem 23 to be inserted into the valve core 24. The valve stem 23 and the valve core 24 extend into and connect from both ends of the valve body 26 to fix the valve stem 23, the valve core 24, and the valve body 26.

[0048] like Figure 5 As shown, a handwheel 21 is fixedly installed at the end of the valve stem 23 away from the main water distributor 1. The handwheel 21 is installed on the valve stem 23 in an inverted manner, which eliminates the cumbersome installation and connection using screws, thereby reducing material and labor costs. An open retaining ring 232 is installed on the valve stem 23, and the bottom of the open retaining ring 232 is engaged with the valve body 26. The valve stem 23 and the valve body 26 are assembled by snapping together through the open retaining ring 232, which is simple, reliable, and has good sealing performance. An annular groove 28 is provided between the valve stem 23 and the handwheel 21.

[0049] like Figure 1As shown, a decorative buckle 22 is fixedly installed at the end of the handwheel 21 away from the main water distributor 1. The decorative buckle 22 can be set in different colors to distinguish between hot water and cold water.

[0050] like Figure 5 As shown, the control valve 2 is provided with several sealing rings 29, which are disposed between the valve stem 23 and the valve body 26, and between the valve body 26 and the valve sleeve 27.

[0051] like Figure 9 As shown, an adapter 38 is inserted into the end of the valve core connector 34 away from the main water pipe 1 of the manifold. The valve core connector 34 and the adapter 38 are provided with water distribution channels 37. The angle makes the water distribution channels form a natural upward / outward guiding trend, which is conducive to the smooth discharge of water carrying air bubbles. It is not easy to form air pockets in the valve cavity and the root of the branch, thus avoiding problems such as insufficient heating and poor circulation caused by air blockage.

[0052] like Figures 7-9 As shown, the valve core connector 34 has a third external thread 33 on the outer side of its bottom, a nut 31 is installed on the outside of the valve core connector 34, and a third internal thread 311 is provided on the inner side of the nut 31; a retaining ring 32 is fitted on the inner side of the bottom of the valve core connector 34.

[0053] like Figure 7 As shown, the top of the connecting block 35 is provided with a rounded corner 36. The rounded corner 36 avoids damage to the sealing gasket 25 and extends the service life of the sealing gasket 25. At the same time, the inclined surface increases the contact area between the valve core 24 and the sealing gasket 25, so that when the valve core 24 is closed, the force direction of the contact surface between the sealing gasket 25 and the valve seat is more reasonable, the sealing pressure distribution is uniform, and it is not easy to have uneven load or side wear. It is not easy to fail or leak after long-term opening and closing, thus extending the service life of the seal.

[0054] Furthermore, the valve sleeve 27 and the valve core connector 34 are connected to the main water distributor 1 by welding.

[0055] Furthermore, the main pipe of the manifold 1 is made of stainless steel pipe through one-piece high-pressure molding, which has high pressure resistance, a robust structure, lighter weight, and lower cost. The valve body 26, valve stem 23, valve core 24, valve sleeve 27, valve core connector 34, adapter 38, and nut 31 are all made of stainless steel. Compared with copper manifold devices, this improves the bending resistance of the pipe body, is not easy to rust, has a longer service life, and is less expensive. In addition, since the density of stainless steel is lower than that of copper, this device has a lightweight design compared to existing manifold devices, which can meet the needs of different usage scenarios. The application of the one-piece high-pressure molding process also ensures that the pipe body of 2-12 or more branch products has good product quality and does not bend during production.

[0056] Furthermore, the control valve 2 is an electric valve, and the water distributor is equipped with a matching temperature control valve to achieve automated temperature control and meet the needs of smart homes.
