Description

Technical Field

[0001] The utility model relates to the technical field of valve body equipment, in particular to a two-inlet and three-way one-way valve body. Background Art

[0002] Most under-the-counter water purification and filtration systems are stand-alone systems with a single water path for inlet and outlet. When the filtration system needs to have multiple water paths or to prevent backflow, additional structural components are required, including three-way valves, one-way valves, connecting pipes, elbows, and other components. This complicates the water path in the filtration system. As more components are required, the overall space occupied by the stand-alone filtration system increases, and disassembly and assembly become more complex.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1

[0023] As shown in the figure, a one-way valve assembly 2 is arranged in the center hole 111 of the valve body 11 of the valve body assembly. The valve body 11 is provided with a first channel 14 and a second channel 15. The axial direction of the center hole 111 of the valve body 1 is perpendicular to the first channel 14 and the second channel 15.

[0024] The ports of the first channel 14 and the second channel 15 are provided with a welding-free component 16. The welding-free component is a common component at the pipe connection port, so it will not be described in detail in the application.

[0025] An outer sealing ring 12 at the water inlet end and a first water inlet waterway sealing ring 13 are provided at the water inlet end of the valve body 11, and a sealing ring 112 is also provided on the outer wall of the other side of the valve body 11. The one-way valve assembly 2 includes a first waterway water outlet inner core 21, an inner core valve body sealing ring 22, an inner core water outlet sealing ring 23, a one-way valve bracket 24, a valve core 25, a valve core sealing ring 251, a spring 27, a valve seat 26 and a valve seat sealing ring 261. The inner core valve body sealing ring 22 and the inner core water outlet sealing ring 23 are provided on the first waterway water outlet inner core 21. The first waterway water outlet inner core 21 is connected to the inner core 25 through the one-way valve bracket 24. The inner core sealing ring 251 is provided on the inner core 25. A spring 27 is provided between the connection between the inner core 23 and the valve seat 26. A valve seat sealing ring 261 is provided on the valve seat 26.

[0026] like Figure 4 As shown, the water inlet position of the first channel 14 is located at the center of the water inlet end of the valve body 11, that is, the water inlet end 31 of the first water path, and the water inlet position of the second channel 15 is located at the center of the water inlet end away from the valve body 11, that is, the water inlet end 32 of the second water path.

[0027] Example 2

[0028] The first waterway enters from the water inlet end 31 of the first waterway at the center hole of the valve body 11. The valve core 25 is driven to open by water pressure, and the valve core 25 is no longer in contact with the valve seat 26, which makes the first waterway open. After the first waterway is opened, Figure 5 As shown, the first water outlet of the first waterway is from the coaxial direction of the one-way valve assembly 2, and the first channel 14 perpendicular to the one-way valve assembly 2 is used as the second water outlet of the first waterway.

[0029] It should be noted that the one-way valve relies on the spring 27 to separate and tightly fit the valve core 25 from the valve seat, thereby closing and opening the waterway. This is a prior art method, so the opening and closing of the valve core of the one-way valve will not be described in detail in this application.

[0030] like Figure 6 As shown, water entering from the water inlet end 32 of the second waterway at a position deviating from the central hole 111 of the valve body 11 will be used as the water outlet of the second waterway from the second channel 15.

[0031] From the above, it can be seen that the utility model realizes the multi-stage waterway situation, and the overall structure is simple and small in size, and also solves the problem of cumbersome disassembly and assembly.

[0032] Example 3

[0033] The water entering the first waterway can also serve as the return water of the first waterway. An energy storage device can be installed at the second outlet of the first waterway, that is, the first channel 14. When the energy storage device needs to return, the first water outlet of the first waterway is closed. Under the action of the spring 27 in the one-way valve assembly, the valve core 25 rebounds, and the sealing ring of the valve core 25 fits with the valve seat 26, closing the first outlet of the first waterway, and the water in the energy storage tank returns from the second outlet.

[0034] The valve core 25 is closed, and the second outlet of the first water channel is closed by the valve core. The water in the energy storage tank will not flow out from the first outlet of the first water channel. Then the water in the energy storage tank can only enter from the first channel 14 and then flow back to the water inlet end 31 of the first water channel.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in this utility model is defined by the appended claims and their equivalents.
