Description

Technical Field

[0001] The present invention relates to the technical field of valve bodies, and particularly to a flow direction control device for pipelines. Background Art

[0002] With the improvement of people's living standards, there are more and more water treatment devices at home. Conventional water treatment devices generally include water heaters, water purification devices, and water softening devices, etc. With the progress of technology, different water treatment devices will achieve collaborative operation to obtain high-quality water sources. To save space, centralized control, and meet different installation scenarios, etc., higher requirements are put forward for the laying and control of pipelines.

[0003] At present, water treatment devices cannot achieve collaborative work, and the flow channel control between different water treatment devices is also relatively single and scattered. Therefore, a device that can centrally control the flow channels of different water treatment devices has gradually been proposed. However, existing flow channel centralized control devices generally can only control the flow of local flow channels, that is, the flow channel is controlled by a rotatable baffle. When the baffle does not cover the flow channel, the flow channel can remain connected, and when the baffle covers the flow channel, the flow channel will not be connected. And the existing communication holes and baffles are usually designed with a symmetric structure, resulting in the ability to only control the flow of local flow channels, thus unable to achieve the purpose of all flow channels flowing together, and further unable to meet the switching requirement between the flow of local flow channels and the flow of all flow channels.

[0004] Therefore, it is of great significance to study a flow channel centralized control device that can switch between the flow of local flow channels and the flow of all flow channels. Summary of the Invention

[0005] The purpose of the present invention is to provide a flow direction control device for pipelines to solve the problem that the existing flow channel centralized control device cannot meet the switching requirement between the flow of local flow channels and the flow of all flow channels.

The multiple sector surfaces with the first gap or the second gap make the communication holes equivalent to having a baffle gap.

When the second communication hole rotates to be communicated with the water outlet through hole, only the second communication hole is communicated with the water outlet through hole; while the third communication hole is arranged on four sector surfaces. When the third communication hole rotates to be communicated with the water outlet through hole, only the third communication hole is communicated with the water outlet through hole, so as to realize the communication in a specific preset state when the valve rotates to a specific position.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] In the prior art, a communicating water valve that can control the water inlet and outlet of multiple water pipes generally adopts the working principle of a six-way valve, and controls the water flow in and out of different holes through a rotatable communicating flap. Since the communicating flap is usually designed with open holes or closed holes at both ends, it often can only control the water flow communication of any two or any four communicating holes, that is, the partial communication of the communicating holes. When the user needs to switch from the partial communication of the communicating holes to the communication of all the communicating holes, the water valves in the prior art often cannot achieve the purpose. For example, a ring-shaped multi-way valve core structure and a water valve (CN115949772A), which controls the water inlet and outlet of multiple water holes by designing a rotatable flap and covering or uncovering both ends of the flap with the through-holes, but it still cannot realize the switching between the water outlet of all the water holes and the water outlet of partial water holes.

[0041] To solve the above problems, this solution proposes a flow direction control device for pipelines. Please refer to Figures 1 to 14, including a valve cover 1, a valve 2, a water inlet / outlet cover 3 and a water inlet / outlet pipe 5. Among them, by designing a special arrangement of the communication hole group 20 on the rotatable valve 2, the connection between the water inlet / outlet pipe 5 and the valve 2 can be such that a single water inlet / outlet pipe 5 is connected to the water storage space 7, or two water inlet / outlet pipes 5 are connected to the water storage space 7, or all the water inlet / outlet pipes 5 are connected to the water storage space 7. That is, a total of eleven connection states of the water inlet / outlet pipes 5 can be achieved, and partial or all of the water inlet / outlet pipes 5 can be connected. With a large number of connection states and convenient control, the accuracy of water use in the water pipes is greatly improved. Specifically, the following will be elaborated with preferred embodiments.

[0042] In the embodiments of the present application, regarding the above-mentioned valve cover 1, valve 2 and water inlet / outlet cover 3, please refer to Figures 1 to 3 , the valve cover 1, valve 2 and water inlet / outlet cover 3 are all coaxially arranged. The valve cover 1 is threadedly connected to the water inlet / outlet cover 3. The water inlet / outlet cover 3 is provided with a water inlet through hole 30 and four water outlet through holes 31. The four water outlet through holes 31 are evenly arranged circumferentially on the water inlet / outlet cover 3. The valve 2 is arranged between the valve cover 1 and the water inlet / outlet cover 3. The valve 2 is rotatably connected to both the water inlet / outlet cover 3 and the valve cover 1. A water storage space 7 is sealed between the valve 2 and the valve cover 1. A communication hole group 20 and a connection through hole 29 for connecting the connecting pipe 11 are provided on the end face of the valve 2 adjacent to the water inlet / outlet cover 3. The water storage space 7 is connected to the water inlet through hole 30 of the water inlet / outlet cover 3. The water storage space 7 and the four water outlet through holes 31 are selectively connected according to a preset state. After adopting this setting method, after the valve 2 rotates, the water outlet through hole 31 of the water inlet / outlet cover 3 will only discharge water when it is connected to the communication hole group 20 of the valve 2. It is possible to control the connection of a single, two adjacent, two opposite or all the water outlet through holes 31.

[0043] Among them, the preset state includes at least three connection states. Please refer to Figures 11 to 14 , the first connection state is that a single water outlet through hole 31 is connected to the water storage space 7, the second connection state is that two water outlet through holes 31 are connected to the water storage space 7, and the third connection state is that all the water outlet through holes 31 are connected to the water storage space 7. After adopting this setting method, the connection between the communication hole group 20 and the four water outlet through holes 31 can achieve a total of eleven connection methods of the water outlet through holes 31, that is, as Figure 9 shown, any one of the four water outlet through holes 31 is connected, or any two of the four water outlet through holes 31 are connected, or all of the four water outlet through holes 31 are connected, so as to realize the coordinated cooperation of different water-using devices.

[0044] It should be noted that the valve 2 and the valve cover 1 are sealed and connected through a sealing ring.

[0045] In some possible embodiments of the present application, the number of water outlet through-holes 31 that can be connected is more than four, and may be five, six, or multiple within a reasonable range, resulting in the number of adjacent water outlet through-holes 31 that can be connected being more than two, and may be three, four, or multiple within a reasonable range. Similarly, the number of opposite water outlet through-holes 31 that can be connected is also more than two, and may be three, four, or multiple within a reasonable range. Those skilled in the art can select the specific number according to their actual situation.

[0046] In the embodiments of the present application, for the valve cover 1, please refer to Figure 5 and Figure 6 , the valve cover 1 includes a cover body 10 and a connecting pipe 11. The cover body 10 is fixedly connected to the connecting pipe 11. An external thread is provided on the outer wall of the bottom of the connecting pipe 11. A water passing through-hole 110 is provided on the connecting pipe 11. The connecting pipe 11 is threadedly connected to the water inlet through-hole 30 of the water inlet and outlet cover 3. The rotating push rod 12 is inserted into the connecting pipe 11, and the rotating push rod 12 is threadedly connected to the connecting pipe 11. A stop block is provided on the outer peripheral wall of the rotating push rod 12. A gland 13 is provided outside one end of the rotating push rod 12. The gland 13 is snap-connected to the cover body 10 to limit the rotating push rod 12. The handwheel 14 is connected to the rotating push rod 12 through a transition fit. After adopting this setting method, the user tightens and fixes the water inlet and outlet cover 3 and the valve cover 1 through the connecting pipe 11. By rotating the rotating push rod 12 clockwise to the bottom end, the stop block of the rotating push rod 12 moves to the water passing through-hole 110 of the connecting pipe 11, thereby closing the water passing through-hole 110 and preventing water flow. By rotating counterclockwise to the top end, after the stop block of the rotating push rod 12 moves away from the water passing through-hole 110 of the connecting pipe 11, the water passing through-hole 110 is opened and water flow can pass through. When water flows through, the water will fill the entire water storage space 7.

[0047] Moreover, after the valve cover 1 and the water inlet and outlet cover 3 are tightened, an installation space is left between them. This installation space is used to install the valve 2, so that the valve 2 can be clamped and fixed between them to achieve the free rotation of the valve 2.

[0048] In the embodiments of the present application, for the valve 2, please refer to Figure 7 , Figures 9 to 14 , the communication hole group 20 on the valve 2 is arranged on multiple interconnected fan-shaped surfaces, including a first communication hole 200, multiple second communication holes 201, and multiple third communication holes 202. Among them, the first communication hole 200 is arranged in a matching manner with any one of the water outlet through-holes 31. The first communication hole 200 is used to connect the water outlet through-hole 31 and the water storage space 7 in a first communication state, that is, as shown in Figure 11 ; multiple second communication holes 201 are arranged in a matching manner with any two water outlet through-holes 31. The multiple second communication holes 201 are used to connect the water outlet through-hole 31 and the water storage space 7 in a second communication state, that is, as shown in Figure 12 andFigure 13 As shown; a plurality of third communication holes 202 are arranged in matching with all the water outlet through holes 31, and the plurality of third communication holes 202 are used to connect the water outlet through holes 31 and the water storage space 7 in a third communication state, that is, as Figure 14 shown. After adopting this setting method, when the valve 2 rotates to make the first communication hole 200 communicate with the water outlet through hole 31, only one water outlet through hole 31 can communicate with the water storage space 7, so that only the water-using device connected to this water outlet through hole 31 can use water; when the valve 2 rotates to make the second communication hole 201 communicate with the water outlet through hole 31, only two water outlet through holes 31 can communicate with the water storage space 7, so that only the two water-using devices connected to this water outlet through hole 31 can use water; when the valve 2 rotates to make the third communication hole 202 communicate with the water outlet through hole 31, all four water outlet through holes 31 can communicate with the water storage space 7, so that the water-using devices connected to these four water outlet through holes 31 can all use water, thus realizing the collaborative work among multiple water-using devices.

[0049] Among them, the total number of the second communication holes 201 is four, as Figure 12 and Figure 13 shown. Two of the second communication holes 201 are arranged in matching with two adjacent water outlet through holes 31, and the other two second communication holes 201 are arranged in matching with two opposite water outlet through holes 31. After adopting this setting method, it can simultaneously achieve the purpose of discharging water through the adjacent water outlet through holes 31 ( Figure 12 ) and discharging water through the opposite water outlet through holes 31 ( Figure 13 ). When the second communication hole 201 rotates to the position of the adjacent or opposite water outlet through hole 31, the opposite or adjacent water outlet through hole 31 can be made to communicate with the water storage space 7.

[0050] It should be noted that when the first communication hole 200 communicates with the water outlet through hole 31, the second communication hole 201 and the third communication hole 202 do not communicate with the water outlet through hole 31. Similarly, when the second communication hole 201 communicates with the water outlet through hole 31, the first communication hole 200 and the third communication hole 202 do not communicate with the water outlet through hole 31. The same is true for the third communication, so it will not be elaborated here.

[0051] For the fan-shaped surface of the valve 2, the fan-shaped surface refers to Figure 10The first sector surface 22, the second sector surface 23, the third sector surface 24, the fourth sector surface 25, and the fifth sector surface 26 that are sequentially connected to each other in a clockwise manner. There is a first gap 27 between the first sector surface 22 and the second sector surface 23, a first gap 27 between the second sector surface 23 and the third sector surface 24, a first gap 27 between the third sector surface 24 and the fourth sector surface 25, a second gap 28 between the fourth sector surface 25 and the fifth sector surface 26, and a second gap 28 between the fifth sector surface 26 and the first sector surface 22. After adopting this setting method, multiple sector surfaces with the first gap or the second gap make the communication holes equivalent to having a baffle gap. The first communication hole 200, the second communication hole 201, and the third communication hole 202 need to rotate to the corresponding positions to communicate with the water outlet through hole 31.

[0052] Among them, as Figure 9 shown, the second communication hole 201 and the third communication hole 202 are provided on the first sector surface 22, the second communication hole 201 and the third communication hole 202 are provided on the second sector surface 23, the first communication hole 200 is provided on the third sector surface 24, the third communication hole 202 is provided on the fourth sector surface 25, and two second communication holes 201 and the third communication hole 202 are provided on the fifth sector surface 26. The first communication hole 200 is arranged alone on the sector surface. When the first communication hole 200 rotates to communicate with the water outlet through hole 31, only the first communication hole 200 communicates with the water outlet through hole 31; while the second communication hole 201 is arranged on four sector surfaces. When the second communication hole 201 rotates to communicate with the water outlet through hole 31, only the second communication hole 201 communicates with the water outlet through hole 31; and the third communication hole 202 is arranged on four sector surfaces. When the third communication hole 202 rotates to communicate with the water outlet through hole 31, only the third communication hole 202 communicates with the water outlet through hole 31, so as to realize the communication in a specific preset state when the valve 2 rotates to a specific position.

[0053] It should be noted that the first gap 27 and the second gap 28 do not refer to the gap between ordinary openings, but are gaps designed through special means. On the continuously adjacent communication holes, the first gap 27 is the distance between one communication hole and the third communication hole counted from the clockwise or counterclockwise side, that is, the distance between two communication holes with one communication hole in between, and the second gap 28 is the distance between two communication holes with two communication holes in between.

[0054] On the above-mentioned first sector surface 22, please refer to Figure 9 and Figure 10 , a second communication hole 201 is provided on the side adjacent to the second sector surface 23, and a third communication hole 202 is provided on the side adjacent to the fifth sector surface 26. On the above-mentioned second sector surface 23, please refer to Figure 10, on one side adjacent to the first sector surface 22, there is a second communication hole 201, and on one side adjacent to the third sector surface 24, there is a third communication hole 202. Regarding the above-mentioned fifth sector surface 26, please refer to Figure 10 , on one side adjacent to the first sector surface 22, there is a second communication hole 201, and on one side adjacent to the fourth sector surface 25, there is another second communication hole 201. A third communication hole 202 is provided between the two second communication holes 201.

[0055] It should be noted that since there is only one first communication hole 200 on the third sector surface 24 and only one third communication hole 202 on the fourth sector surface 25, no additional description will be given.

[0056] After the first communication hole 200, the second communication hole 201, and the third communication hole 202 are arranged in such a way, as Figure 9 and Figure 10 shown, the first communication hole 200 is arranged separately. As Figure 9 and Figure 10 shown, the second communication holes 201 are arranged adjacent to and opposite to each other. As Figure 9 and Figure 10 shown, the third communication holes 202 are arranged at the four corners, so as to realize the staggered arrangement of multiple communication holes to achieve the coordinated connection or closure of the water-using device.

[0057] In addition, four handles 21 are also provided on the outer peripheral wall of the valve 2. The four handles 21 are arranged offset. The four handles 21 are evenly arranged on the left side as shown in Figure 10 , that is, on one side adjacent to the fifth sector surface 26, the first sector surface 22, and the second sector surface 23. The four handles 21 correspond to four different water outlet situations. When each handle 21 rotates to the position where the magnet patch is installed on the valve cover 1, it represents that one of the situations occurs. The specific flow control in that category is determined according to the text or letter markings on the handle 21. When in one of the situations, there will be another same or different flow control after rotating 90 degrees. Then, only corresponding markings need to be made through text or letters, and the present invention uses four arrows for marking. Regardless of which position the handle 21 is at among the four magnet patches, the marking is made with the same orientation as the standard.

[0058] In the embodiment of the present application, regarding the inlet and outlet cover body 10, please refer to Figure 8 , the inlet and outlet cover body 10 is provided with an inlet through hole 30 and four outlet through holes 31. The inlet through hole 30 is arranged at the center of the inlet and outlet cover body 10. The four outlet through holes 31 are evenly arranged in a circumferential manner around the inlet through hole 30. An internal thread is also provided on the inner wall of the inlet through hole 30. The internal thread is used for threaded connection with the valve cover 1 to fix the valve cover 1 and the inlet and outlet cover body 10.

[0059] In some embodiments of the present application, please refer to Figure 1 , it further includes an inlet and outlet pipe 5, a fixing nut 4 and a valve barrel 6. The fixing nut 4 is sleeved outside the inlet and outlet pipe 5, and the inlet and outlet pipe 5 is threadedly connected to the fixing nut 4, and the fixing nut 4 is threadedly connected to the valve barrel 6; the inlet and outlet cover 3 is clamped inside the valve barrel 6, and the inlet and outlet pipe 5 is inserted and connected to the inlet and outlet cover 3. The integrally printed inlet and outlet pipe 5 makes it more convenient to connect the water outlet through hole 31 to the water using device.

[0060] It should be noted that a sealing ring is provided at the connection of the inlet and outlet pipe 5, and the sealing ring can play a sealing role.

[0061] In some embodiments of the present application, for the valve barrel 6, four mounting magnet patches are evenly arranged on the circumference of the valve barrel 6. The valve barrel 6 is provided with a groove, and the magnet patch at the groove can limit the valve 2 so that it cannot rotate without reaching a certain force. This design is because the four water outlets are also evenly distributed in a circle. Therefore, when the handle of the valve 2 rotates through a certain angle, that is, 90 degrees, the conducting channel can be changed. After adopting this setting method, the valve 2 will receive resistance at the beginning of the rotation process, which plays a role in preventing its rotation. At the same time, it can reach the final position more quickly and accurately when the rotation is almost completed, realizing precise rotation control of the valve 2.

[0062] In some embodiments of the present application, for the inlet and outlet pipe 5, the inlet and outlet pipe 5 is integrally prepared by 3D printing. The inlet pipeline of the inlet and outlet pipe 5 is located in the middle of the other four outlet pipelines, and the four outlet pipelines are arranged in a circular array. After adopting this setting method, the water flow enters from the middle, which can greatly improve the stability of the device.

[0063] Moreover, when printing the inlet and outlet pipe 5, by selecting and changing the printing direction and designing the angle during modeling, the support outside the pipeline can be greatly reduced and there is no support inside the pipeline, so that the inlet and outlet pipe 5 prepared by 3D printing can reduce the support inside the pipeline.

[0064] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches are also regarded as the protection scope of the present invention.
