The invention provides a waste water valve.
In the embodiment of the invention, as shown in fig. 1, the wastewater valve comprises a water inlet end 100 and two water outlet ends 200, wherein the water inlet end 100 is connected with the wastewater outlet end of the reverse osmosis water purifier; one water outlet end 200 is connected with the raw water inlet end of the reverse osmosis water purifier, and the other water outlet end 200 is empty.
Specifically, the reverse osmosis water purifier is a system for treating water according to the reverse osmosis principle, and is provided with a raw water inlet end, a pure water outlet end and a waste water outlet end, wherein components such as a booster pump, a reverse osmosis filter element and the like are arranged in the reverse osmosis water purifier. In the water production process of the reverse osmosis water purifier, raw water flows through a reverse osmosis filter element under the action of a booster pump, is separated into pure water and wastewater with higher concentration, and is discharged respectively. The recovery rate of the reverse osmosis water purifier is determined by the ratio of pure water output to raw water input, and the higher the recovery rate is, the more pure water is generated per unit raw water, and the better the water saving performance of the reverse osmosis water purifier is. There are various methods for improving the recovery rate of the reverse osmosis water purifier, for example, reducing the flow rate of wastewater, and correspondingly, reducing the flow rate of raw water, and the residence time in the reverse osmosis cartridge is longer, so that sufficient filtration is obtained to produce as much pure water as possible. However, when the flow rate is too low, impurities in raw water or wastewater, particularly calcium salt, magnesium salt and the like, are likely to form precipitates in waterways, particularly in waterway narrow parts such as a reverse osmosis filter element and a small-hole water outlet, and are likely to be blocked when serious, so that the reverse osmosis water purifier cannot work normally. Therefore, another method is generally adopted, namely, the flow rate of the wastewater is maintained, but at least part of the wastewater is led back to the raw water inlet end of the reverse osmosis water purifier to be filtered again, so as to achieve the purpose of saving water. In order to simplify the structure of the reverse osmosis water purifier, a waste water valve with a water inlet end 100 and two water outlet ends 200 is arranged at the waste water outlet end, wherein the water inlet end 100 is connected with the waste water outlet end, one water outlet end 200 is connected with the raw water inlet end of the reverse osmosis water purifier so as to control the flow of waste water flowing back into the raw water inlet end, the other water outlet end 200 is empty, and in particular, the other water outlet end 200 can be directly connected with the outside to discharge waste water or connected with other waste water treatment equipment so as to further treat the waste water. The waste water valve is integrally arranged on the shell, and two waterways which are respectively communicated with the water inlet end 100 and the two water outlet ends 200 are arranged in the shell. The water outlet 200 may be provided with a corresponding wastewater proportioner 300 and/or solenoid valve 400, etc. to control the flow rate of each path of wastewater, etc. respectively. The integrally arranged waste water valve can simplify the structure of the reverse osmosis water purifier, and a plurality of waste water valves are not required to be arranged in the waste water valve, so that the assembly process of the reverse osmosis water purifier is simplified, and the space utilization rate of the reverse osmosis water purifier is higher.
In the technical scheme of the invention, by arranging the waste water valve with the water inlet end 100 and the two water outlet ends 200, wherein the water inlet end 100 is connected with the waste water outlet end of the reverse osmosis water purifier, one water outlet end 200 is connected with the raw water inlet end of the reverse osmosis water purifier, and the other water outlet end 200 is empty, so that part of waste water flowing out of the waste water outlet end of the reverse osmosis water purifier flows back into the raw water inlet end of the reverse osmosis water purifier for filtering again, thereby improving the recovery rate and realizing water saving. The integrally arranged waste water valve with the two water outlet ends 200 simplifies the waterway of the reverse osmosis water purifier, and a plurality of waste water valves are not required to be arranged in the waterway to control the diversion of waste water, so that the number of parts of the reverse osmosis water purifier is reduced, the whole structure is simplified, the assembly is convenient, and the space utilization rate is improved.
In one embodiment of the present invention, as shown in fig. 1, a water outlet 200 on the left side of the figure is provided with a wastewater proportioner 300. The wastewater proportioner 300 throttles the wastewater outlet end, adjusts the wastewater flow rate, and generally comprises a small-hole water outlet, and can adjust the wastewater flow rate by changing the structural parameters such as the aperture of the small-hole water outlet. As shown in fig. 2, in a specific example, the wastewater proportioner 300 includes a first baffle 310 and a second baffle 320, the first baffle 310 is provided with a first orifice 311, and a gap is formed between the second baffle 320 and the first baffle 310, which is equivalent to forming a second orifice 330, so as to improve the throttling effect of the wastewater proportioner 300. It should be noted that the wastewater proportioner 300 may be provided at either one of the water outlet ends 200 of the wastewater valve or at both water outlet ends 200 of the wastewater valve to adjust the flow rate of wastewater at each water outlet end 200, and is not limited to the case shown in fig. 1.
In this embodiment, as shown in fig. 1, a water outlet 200 on the right side of the figure is provided with a solenoid valve 400, the solenoid valve 400 has a solenoid valve water inlet 410 communicated with the water inlet 100, a solenoid valve first water outlet 420 and a solenoid valve second water outlet 430 communicated with the water outlet 200, the solenoid valve first water outlet 420 can be opened or closed, and the water outlet flow of the solenoid valve first water outlet 420 is larger than the water outlet flow of the solenoid valve second water outlet 430. The electromagnetic valve first water outlet 420 is controlled to be opened or closed through electromagnetic action so as to meet the wastewater flow rate requirements under different conditions. In the normal water production process, the solenoid valve first water outlet 420 is closed, the wastewater flows out from the solenoid valve second water outlet 430, the wastewater flow rate is relatively small to maintain a high recovery rate, and in the flushing process, the solenoid valve first water outlet 420 is opened, a large amount of wastewater flows out from the solenoid valve first water outlet 420, the wastewater flow rate is increased, so that sediment and the like in the waterway system of the reverse osmosis water purifier are peeled off due to flushing and discharged out of the waterway system along with the water flow, and the performance of the reverse osmosis water purifier is improved.
Further, the solenoid valve 400 includes a housing 440, an inner wall 450 and an inner gasket 460, wherein the housing 440 is provided with a solenoid valve water inlet 410 and a solenoid valve first water outlet 420; the inner wall 450 is arranged in the shell 440, one end of the inner wall 450 connected with the shell 440 is arranged around the electromagnetic valve water inlet 410, the inner wall 450 is provided with the electromagnetic valve second water outlet 430, the inner wall 450 is internally provided with a first water containing cavity 470, and a second water containing cavity 480 is formed between the inner wall 450 and the shell 440; the inner sealing pad 460 is movably disposed in the housing 440, and the inner sealing pad 460 has a first position surrounding an end of the inner wall away from the housing to isolate the first water containing cavity 470 from the second water containing cavity 480, and a second position separated from an end of the inner wall away from the housing to communicate the first water containing cavity 470 with the second water containing cavity 480. As shown in fig. 1, when the solenoid valve 400 is in a closed state, the inner sealing pad 460 is located at the first position, and at this time, the waste water flows into the first water containing cavity 470 from the solenoid valve water inlet 410, and then flows out of the first water containing cavity 470 from the solenoid valve second water outlet 430, wherein the solenoid valve second water outlet 430 is a small hole water outlet, so as to realize throttling of the waste water. However, since the wastewater continuously flows into the first water chamber 470 of the solenoid valve and the flow rate is slow, scale is easily formed at the first water chamber 470 and the second water outlet 430 of the solenoid valve, so that the inner packing 460 cannot be normally attached to the inner wall 450 to isolate the first water chamber 470 and the second water chamber 480, or the second water outlet 430 of the solenoid valve is blocked, resulting in the failure of the reverse osmosis water purifier to normally operate. Therefore, as shown in fig. 3, the inner sealing gasket 460 of the solenoid valve 400 further has a second position separated from the inner wall 450, at this time, the first water containing cavity 470 is communicated with the second water containing cavity 480, so that the solenoid valve water inlet 410 is communicated with the solenoid valve first water outlet 420, and since the water outlet flow of the solenoid valve first water outlet 420 is greater than that of the solenoid valve second water outlet 430, a large amount of wastewater flows out from the solenoid valve first water outlet 420, and the flow rate in the waterway system is increased, thereby playing a role of flushing, so that scale at all positions in the waterway system is stripped and drained along with the water flow, so as to maintain the normal operation of the reverse osmosis water purifier. Wherein the change in position of the inner seal 460 is accomplished by electromagnetic action. It should be noted that the solenoid valve 400 may be provided at either of the outlet ends 200 of the waste valve or at both ends of the waste valve. When the water outlet end 200 connected to the raw water inlet end 100 of the reverse osmosis water purifier is provided with the solenoid valve 400, a large amount of wastewater generated during the washing process can be filtered again to achieve water saving.
In this embodiment, the waste water valve further includes a scale inhibitor module 500, wherein the scale inhibitor can disperse the poorly soluble salt in the water, prevent or interfere with precipitation of the poorly soluble salt, scale formation, and the like under the actions of chelation, dispersion, lattice distortion, and the like, so as to maintain the normal operation of the reverse osmosis water purifier. The scale inhibitor module 500 may be disposed between the water inlet end 100 and the scale prone portion of the waste water valve alone or integrally with other portions of the waste water valve. Wherein, the part of the waste water valve which is easy to scale is usually positioned at the part with narrower pores such as a small-pore water outlet. In this embodiment, the scale inhibitor module 500 is integrally disposed with the solenoid valve 400, as shown in fig. 1, the solenoid valve 400 includes an end cover 490 detachably connected to the solenoid valve, the end cover 490 is disposed at the outer side of the solenoid valve water inlet 410, the end cover 490 encloses with the housing 440 to form a containing cavity 491, and the scale inhibitor module 500 is detachably mounted in the containing cavity 491 to adsorb scale-forming ions in the wastewater, thereby avoiding blocking the solenoid valve water inlet 410, the solenoid valve first water outlet 420 and the solenoid valve second water outlet 430. The end cap 440 may be coupled to the solenoid valve 400 by screws, snap-fit, or the like. By the arrangement mode, the scale inhibitor module 500 is convenient to replace after the reverse osmosis water purifier runs for a period of time, so that the effect of better preventing scaling is realized, and the service lives of the reverse osmosis filter element and the electromagnetic valve 400 are prolonged.
Since the wastewater proportioner 300 also has small hole water outlets, scale is likely to cause blockage when it is precipitated at the small hole water outlets, a scale inhibitor module 500 may also be provided between the water inlet end 100 and the wastewater proportioner 300 to extend the service life of the wastewater proportioner 300.
In addition, the scale inhibitor module 500 is arranged in the waste water valve, and scale ions and the like in waste water at the water outlet end 200 communicated with the raw water inlet end 100 are filtered, so that the efficiency of filtering again by the reverse osmosis filter element can be effectively improved, scale is reduced, and the service life of the reverse osmosis filter element is prolonged.
A one-way valve is provided between the water inlet end 100 and at least one water outlet end 200 to prevent water flow from the water outlet end 200 to the water inlet end 100. In the working process of the reverse osmosis water purifier, a booster pump is arranged on one side of the water inlet end 100 so as to promote the filtration of raw water, if the booster pump is suddenly out of pressure, water in the waterway flows back, impurities and the like in the wastewater are easily brought into the water path system, the reverse osmosis water purifier is easy to scale, the service life is shortened, and the arrangement of the one-way valve 600 can effectively avoid the phenomenon. Further, the check valve 600 is disposed between the water inlet end 100 and the scale inhibitor module 500 to prevent water from flowing from the scale inhibitor module 500 to the water inlet end 100, so as to prevent a large amount of impurities in the scale inhibitor module 500 from being carried into the waterway system of the reverse osmosis water purifier by the water flow to cause blockage.
The invention also provides a reverse osmosis water purifier, which comprises a raw water inlet end, a waste water outlet end and a waste water valve, wherein the specific structure of the waste water valve refers to the embodiment, and the reverse osmosis water purifier at least has all the beneficial effects brought by the technical schemes of the embodiment because the reverse osmosis water purifier adopts all the technical schemes of the embodiment, and the detailed description is omitted.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
