Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, and particularly relates to a waste water valve applicable to a small flow system. Background Art

[0002] The waste water valve is used for outputting waste water; a patent document with the application number 201821264149.0 and the publication date of March 29, 2019 in China discloses a waste water valve and a water purification device. The valve body includes a water inlet channel and a water outlet channel. A middle hole pipe protrudes in the middle of the inner cavity of the valve body. A communicating waterway is formed between the outer wall of the middle hole pipe and the inner cavity wall of the valve body; the water inlet channel communicates with the communicating waterway, and the water outlet channel communicates with the middle hole pipe; a small flow waste water groove is opened on the edge of the end of the middle hole pipe; it can output waste water with two flow rates.

[0003] However, when the system outputs waste water with a large flow rate, the water inlet and the water outlet are communicated, and all the waste water input from the water inlet flows out through the water outlet. The water output of the waste water is large. When the waste water discharge amount increases, the pure water amount decreases; when used in a small flow water treatment system, when all the waste water input from the water inlet flows out through the water outlet, no pure water will be produced. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a waste water valve applicable to a small flow system, which can output waste water with two flow rates without affecting the production of pure water in the small flow water treatment system when discharging waste water.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A waste water valve applicable to a small flow system described in the utility model includes a valve body. The valve body is connected with a water inlet channel and a water outlet channel. A first cavity and a second cavity are arranged in the valve body. The first cavity and the second cavity are switched on and off by a valve core; the water outlet channel is provided with a first water outlet hole and a second water outlet hole. The first water outlet hole communicates with the first cavity, and the second water outlet hole communicates with the second cavity; the sum of the cross-sectional areas of the first water outlet hole and the second water outlet hole is smaller than the cross-sectional area of the water inlet channel.

[0007] Preferably, the proportion of the cross-sectional area of the first water outlet hole in the cross-sectional area of the first cavity is 2%-5%; the proportion of the cross-sectional area of the second water outlet hole in the cross-sectional area of the second cavity is 5%-10%.

[0008] Preferably, the proportion of the cross-sectional area of the first water outlet hole in the cross-sectional area of the first cavity is 2.7%.

[0009] Preferably, the proportion of the cross-sectional area of the second water outlet hole in the cross-sectional area of the second cavity is 7.2%.

[0010] Preferably, the cross-sectional area of the first water outlet hole is the same as that of the second water outlet hole.

[0011] Preferably, the first water outlet hole is arranged on the side wall of the water outlet channel.

[0012] Preferably, the second water outlet hole is arranged on the side wall of the water outlet channel.

[0013] Preferably, the first water outlet hole is a round hole, an oval hole or a square hole.

[0014] Preferably, the second water outlet hole is a round hole, an oval hole or a square hole.

[0015] The beneficial effects of the waste water valve applicable to a small flow system according to the present invention compared with the prior art are mainly reflected in:

[0016] Both the first water outlet hole and the second water outlet hole are used to discharge waste water; when the first cavity is cut off from the second cavity, the waste water entering from the water inlet channel is discharged through the first water outlet hole; when the first cavity is communicated with the second cavity, part of the waste water is discharged through the first water outlet hole, and the other part of the waste water flows from the first cavity into the second cavity and then is discharged through the second water outlet hole; by independently discharging waste water through the first water outlet hole and jointly discharging waste water through the first water outlet hole and the second water outlet hole, the waste water valve realizes the waste water output of two flow rates; at the same time, the sum of the cross-sectional areas of the first water outlet hole and the second water outlet hole is smaller than the cross-sectional area of the water inlet channel, so that the waste water flow rate jointly discharged through the first water outlet hole and the second water outlet hole is small, and the generation of pure water in the small flow water treatment system will not be affected when discharging waste water.

[0017] At the same time, the proportion of the cross-sectional area of the first water outlet hole in the cross-sectional area of the first cavity is small, and the proportion of the cross-sectional area of the second water outlet hole in the cross-sectional area of the second cavity is small, so that the influence on the pure water in the small flow water treatment system can be further reduced.

[0018] By arranging the first water outlet hole on the side wall of the water outlet channel, the waste water discharged from the first water outlet hole will flow along the inner wall of the water outlet channel, thereby reducing the impact force between the water flow and the valve body and reducing the noise when discharging waste water. At the same time, by arranging the second water outlet hole on the side wall of the water outlet channel, the waste water discharged from the second water outlet hole will also flow along the inner wall of the water outlet channel, thereby reducing the impact force between the water flow and the valve body and reducing the noise when discharging waste water.

[0019] The present invention can output waste water of two flow rates through the first water outlet hole and the second water outlet hole with small cross-sectional areas, and will not affect the generation of pure water in the small flow water treatment system when discharging waste water.

[0026] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are only for the purpose of illustration.

[0027] This embodiment provides a wastewater valve applicable to a small-flow system, as Figures 1 - 3 shown, including a valve body 1 and a valve seat 2. The valve seat 2 is provided with a valve core (not shown in the figure) and is installed on the valve body 1 for use. The valve seat 2 is a prior art and will not be described in detail here.

[0028] The valve body 1 is connected with a water inlet channel 11 and a water outlet channel 12. A first cavity 13 and a second cavity 14 are arranged in the valve body 1. The first cavity 13 and the second cavity 14 are switched on and off by a valve core. The water outlet channel 12 is provided with a first water outlet hole 15 and a second water outlet hole 16. The first water outlet hole 15 is communicated with the first cavity 13, and the second water outlet hole 16 is communicated with the second cavity 14. The sum of the cross-sectional areas of the first water outlet hole 15 and the second water outlet hole 16 is smaller than the cross-sectional area of the water inlet channel 11.

[0029] Both the first water outlet hole 15 and the second water outlet hole 16 are used for discharging waste water. When the first cavity 13 and the second cavity 14 are cut off, the waste water entering from the water inlet channel 11 is discharged through the first water outlet hole 15. When the first cavity 13 and the second cavity 14 are communicated, a part of the waste water is discharged through the first water outlet hole 15, and another part of the waste water flows from the first cavity 13 into the second cavity 14 and then is discharged through the second water outlet hole 16. By independently discharging waste water through the first water outlet hole 15 and jointly discharging waste water through the first water outlet hole 15 and the second water outlet hole 16, the waste water valve realizes the waste water output of two flow rates. At the same time, the sum of the cross-sectional areas of the first water outlet hole 15 and the second water outlet hole 16 is smaller than the cross-sectional area of the water inlet channel 11, so that the waste water flow rate jointly discharged through the first water outlet hole 15 and the second water outlet hole 16 is small, and the generation of pure water in the small-flow water treatment system will not be affected when discharging waste water.

[0030] The first water outlet hole 15 is arranged on the side wall of the water outlet channel 12. By arranging the first water outlet hole 15 on the side wall of the water outlet channel 12, the waste water discharged from the first water outlet hole 15 will flow along the inner wall of the water outlet channel 12, thereby reducing the impact force between the water flow and the valve body 1 and reducing the noise when discharging waste water. The second water outlet hole 16 is arranged on the side wall of the water outlet channel 12. At the same time, by arranging the second water outlet hole 16 on the side wall of the water outlet channel 12, the waste water discharged from the second water outlet hole 16 will also flow along the inner wall of the water outlet channel 12, thereby reducing the impact force between the water flow and the valve body 1 and reducing the noise when discharging waste water.

[0031] The water inlet channel 11 is provided with a water inlet input end 111 and a water inlet output end 112. The water outlet channel 12 is provided with a water outlet output end 121. The water inlet input end 111 and the water outlet output end 121 are arranged away from the valve body 1. The water inlet output end 112 is arranged on the side wall of the first cavity 13.

[0032] Working principle of the present utility model: Wastewater flows from the inlet input end 111 to the inlet output end 112, and then flows into the first cavity 13. When the first cavity 13 is cut off from the second cavity 14, the wastewater enters the water outlet channel 12 through the first water outlet hole 15, and then is discharged through the water outlet output end 121. When the first cavity 13 is communicated with the second cavity 14, a part of the wastewater enters the water outlet channel 12 through the first water outlet hole 15, and then is discharged through the water outlet output end 121; another part of the wastewater flows from the first cavity 13 into the second cavity 14, then enters the water outlet channel 12 through the second water outlet hole 16, and then is discharged through the water outlet output end 121.

[0033] The proportion of the cross-sectional area of the first water outlet hole 15 in the cross-sectional area of the first cavity 13 is 2% - 5%; the proportion of the cross-sectional area of the second water outlet hole 16 in the cross-sectional area of the second cavity 14 is 5% - 10%.

[0034] In a preferred embodiment, the proportion of the cross-sectional area of the first water outlet hole 15 in the cross-sectional area of the first cavity 13 is 2.7%.

[0035] In a preferred embodiment, the proportion of the cross-sectional area of the second water outlet hole 16 in the cross-sectional area of the second cavity 14 is 7.2%. The proportion of the cross-sectional area of the first water outlet hole in the cross-sectional area of the first cavity is small, and the proportion of the cross-sectional area of the second water outlet hole in the cross-sectional area of the second cavity is small, which can further reduce the impact on pure water in the small-flow water treatment system.

[0036] In a preferred embodiment, the cross-sectional area of the first water outlet hole 15 is the same as that of the second water outlet hole 16. The first water outlet hole 15 is a round hole, an oval hole or a square hole; in a preferred embodiment, the first water outlet hole 15 is a round hole.
