The utility model provides an embodiment of a waste water valve, which is a core part in the operation process of a water purifier system and is mainly used for discharging waste water generated in the filtering process of a water purifier in time. The waste water valve can be arranged in water purifier equipment such as a water purifier, a water purifying drinking machine or a direct drinking machine, and the like, so that the waste water ratio of the water purifier is controlled.
In the embodiment of the present invention, as shown in fig. 1 to 3 and 13, the waste water valve 10 includes a valve body 100 and a throttling flow passage 200, the valve body 100 having a water inlet 110 and a water outlet 120; a water inlet cavity 130 and a water outlet cavity 140 are arranged in the valve body 100, the water inlet cavity 130 is communicated with the water inlet 110, and the water outlet cavity 140 is communicated with the water outlet 120; a throttle channel 200 disposed in the valve body 100 for communicating the water inlet chamber 130 and the water outlet chamber 140; here, there are two planes perpendicular to the extending direction of the throttle flow path 200, and the two planes have different cross-sectional areas or shapes on the throttle flow path 200.
For convenience of description, a cross section taken by a plane perpendicular to the extending direction of the throttle channel 200 will be referred to as follows. Referring to fig. 4, generally speaking, the waste valve 10 includes a valve body 100, the valve body 100 having a water inlet 110 and a water outlet 120, a water inlet chamber 130 and a water outlet chamber 140 disposed in the valve body 100, the water inlet chamber 130 communicating with the water inlet 110, the water outlet chamber 140 communicating with the water outlet 120; the throttle channel 200 is disposed in the valve body 100, and the throttle channel 200 is used for communicating the water inlet chamber 130 and the water outlet chamber 140. Therefore, the waste water can flow in from the water inlet 110 on the valve body 100 and flow out from the water outlet 120 on the valve body 100, then the waste water passes through the throttle flow channel 200 which is arranged in the valve body 100 and is communicated with the water inlet 110 and the water outlet 120, and then the waste water is limited by the throttle flow channel 200 mechanism, so that the anti-blocking effect of the waste water valve 10 is improved under the condition of realizing throttling.
Specifically, the valve body 100 may be provided with an inlet pipe having a water inlet 110, which penetrates into the valve body 100 to communicate the water inlet 110 with the water inlet chamber 130, and likewise, the valve body 100 may be provided with an outlet pipe having a water outlet 120, which penetrates into the valve body 100 to communicate the water outlet 120 with the water outlet chamber 140. Of course, the water inlet pipe and the water outlet pipe may be integrally formed with the valve body 100, or may be separately formed (for example, detachably connected) with the valve body 100, and in this embodiment, the water inlet pipe and the water outlet pipe are integrally formed with the valve body 100 for example. The valve body 100 can be made of hard materials such as ABS, HIPS, PP, PC, POM, etc., or metal or alloy materials, etc., in this embodiment, the valve body 100 is made of POM materials, which have high strength and accuracy, light weight and low cost, and meanwhile, as the material of the valve body 100, it is not easy to rust.
Furthermore, the valve body 100 is provided with a throttle channel 200 for communicating the water inlet chamber 130 and the water outlet chamber 140, and compared with the technical scheme of the prior art in which a throttle hole is provided, the area of the cross section is larger than the opening area of the throttle hole. Like this, improve the stifled effect of preventing of waste water valve 10 through the cross section of increase throttle runner 200, simultaneously, the length of extension throttle runner 200 increases the on-way resistance that the waste water in the waste water valve 10 received to reduce the velocity of flow of waste water. However, considering that the volume of the waste water valve 10 is limited, the length of the throttling channel 200 is limited, and at the same time, only increasing the length may cause that the waste water of the water inlet device is relatively large, in view of this, the technical solution of the present invention increases the local resistance of the throttling channel 200 by setting the variable throttling channel 200 through the structural design of the inner wall of the throttling channel 200, thereby controlling the waste water ratio of the waste water valve 10.
For convenience of describing the variation of the throttle channel 200, the variation of the cross-sectional area of the cross-section of the throttle channel 200 will be described below.
Specifically, there are two planes perpendicular to the extending direction of the throttle flow passage 200, the two planes have different areas or shapes of the cross sections taken through the throttle flow passage 200, the two planes in the extending direction of the throttle flow passage 200 are not the planes specifically existing on the throttle flow passage 200, it is understood that a virtual plane is introduced for explaining the specific structure of the throttle flow passage 200 in detail, wherein the two planes will intersect with the throttle flow passage 200, and the planes where the two intersect form the cross section of the throttle flow passage 200, and the areas or shapes of the cross sections taken through the two planes on the throttle flow passage 200 are different. That is to say, in the technical solution provided by the present invention, the pipe that encloses the throttling flow channel 200 is variably arranged, and such arrangement increases the local resistance of the wastewater in the throttling flow channel 200, further increases the energy loss in the wastewater flowing process, and achieves the effect of reducing the wastewater flow rate.
The change in the area of the cross-section may be a regular change or a random change, wherein the regular change includes, but is not limited to, a gradual increase in the cross-sectional area, a gradual decrease in the cross-sectional area, a gradual increase and then a gradual decrease in the cross-sectional area, or an alternation of a gradual increase in the cross-sectional area and a gradual decrease in the cross-sectional area, or a change in the cross-sectional area according to other rules. The irregular change may be represented by irregular unevenness of the inner wall of the throttling flow passage 200, and the like. There are various shapes and structures of the cross section, for example, random combinations of circular, elliptical, square, polygonal or other irregular shapes and structures, etc., which are not limited herein.
It will be appreciated that the valve body 100 is provided with a throttle channel 200 for communicating the inlet chamber 130 with the outlet chamber 140, and the area of the cross-section is larger than the open area of the throttle bore compared to a conventional finished throttle bore. In this way, the anti-blocking effect of the waste water valve 10 is improved by increasing the cross section of the throttling flow channel 200, and meanwhile, the waste water valve 10 provided by the utility model increases the on-way resistance of the waste water in the waste water valve 10 by increasing the length of the throttling flow channel 200, so as to reduce the flow velocity of the waste water, however, considering that the volume of the waste water valve 10 is limited, the length of the throttling flow channel 200 is limited, and only increasing the length may cause that the waste water of the water inlet device is relatively large, in view of this, the utility model increases the local resistance of the throttling flow channel 200 by changing the cross section areas or the shapes of the cross sections of the throttling flow channel 200 in different flow sections, so as to further reduce the waste water ratio.
In addition, since the same throttling flow rate is achieved in the closed state of the waste water valve 10 under the same water inlet pressure, the total flow resistance of the waste water inside the valve body 100 needs to be equal to that of the waste water in the conventional waste water valve 10. Under the same waste water flow (ml/min), the traditional waste water valve 10 and the waste water valve 10 of the embodiment are simulated and tested, and the measured data are as follows:
as can be seen from the data in the above table, the throttling area of the waste water valve 10 with the changed cross-sectional area or shape of the throttling flow channel 200 is 6 times of the throttling area of the conventional waste water valve 10 under the same waste water flow rate, so that the waste water valve 10 of the present embodiment is not easily blocked, and the service life of the waste water valve 10 can be prolonged.
Therefore, according to the technical scheme, the waste water valve 10 is prevented from being blocked by increasing the flow area of the throttling flow channel 200, the on-way resistance increased by the flow path of the waste water is prolonged, and the area or the shape of the cross section of the throttling flow channel 200 is changed, so that extra local resistance is brought, and the waste water valve 10 is not easy to block.
Referring to fig. 5, 6 and 11, in a preferred embodiment, in view of the limited length of the throttling channel 200 provided in the waste valve 10, in order to provide sufficient local resistance, the throttling channel 200 includes a first channel 201 and a second channel 202 which are communicated with each other; wherein the cross-sectional area of the first flow channel 201 gradually increases; the cross-sectional area of the second flow passage 202 gradually decreases. Preferably, to provide sufficient local resistance even further, the first flow channels 201 and the second flow channels 202 are arranged alternately. Meanwhile, the design can also ensure that the change of the whole flow channel is relatively uniform.
It will be appreciated that in the throttling channel 200 in which the first channel 201 and the second channel 202 are alternately arranged, the inflow waste valve 10 passes through a narrower cross section first and then transitions to a wider cross section, in which process additional local resistance is brought about by the divergent channel. The wastewater then passes from a wider cross-section to a narrower cross-section, in which process additional local resistance is introduced due to the tapering of the flow channels. With the increasing of the gradually-expanding and gradually-reducing quantity, the effects of the local resistance are continuously superposed, and finally, the throttling effect is well realized.
With reference to fig. 5, fig. 6 and fig. 11, on the basis of the above embodiment, in order to further improve the anti-blocking effect of the throttling flow channel 200, the throttling flow channel 200 further includes a third flow channel 203 disposed between the first flow channel 201 and the second flow channel 202, and the cross-sectional areas or shapes of the third flow channel 203, which are obtained by two planes perpendicular to the extending direction of the third flow channel 203, are the same. Similarly, as can be seen from the simulation diagram, the third throttling channel 200 is disposed between the first channel 201 and the second channel 202, and the third throttling channel 200 is disposed so that the region with a large pressure gradient on the throttling channel 200 is relatively dispersed, and is uniformly distributed at the part where the channel gradually expands and gradually contracts and the flow direction changes, and the maximum value of the third throttling channel is smaller than the channel with unchanged cross section area.
Meanwhile, the pressure gradient comparison of the simulation result shows that the pressure gradient of the runner with unchanged section is larger at the flow direction change position of the runner and the maximum value of the pressure gradient is larger. The throttling flow channel 200 of the utility model has the advantages that the areas with larger pressure gradient are comparatively dispersed, the flow channel is uniformly distributed at the positions of gradual expansion and gradual reduction and flow direction change, and the maximum value is smaller than the flow channel with unchanged sectional area. The pressure of the fluid changes more at a certain position in the flowing process, the fluid flows more intensely, and the flowing noise generated by the fluid is larger. The flow channel with unchanged cross section has pressure gradient larger than that of the first embodiment and more concentrated area, and actually generates more noise. Thus, the waste valve 10 of the present invention also has a noise reduction effect.

in addition, any one section of the first flow passage 201 and one section of the second flow passage 202 adjacent to the first flow passage are defined to form a complete expansion and contraction section, wherein the relation between the waste water flow Q in the waste water valve 10 and the section number N of the expansion and contraction section of the throttling flow passage 200 is as follows:

In one embodiment, under the condition that the inlet-outlet pressure difference is 42000pa and other structures and materials of the valve body 100 are not changed, the number N of expansion and contraction sections of the throttling flow channel is changed, the waste water flow data of the waste water valve is tested, and the relation is met through data fitting.

In one embodiment, the wastewater undergoes at least two 90 ° changes in the throttling flow channel 200, so that the design increases that the turning change and the flow direction change of the throttling flow channel 200 both provide larger local resistance for the wastewater flow channel, and the throttling effect is increased.

Referring to fig. 2 and 13, in a preferred embodiment, in order to increase the anti-blocking effect as much as possible, the waste valve 10 further includes a mesh enclosure 500 disposed at the water inlet 110 for intercepting the relatively large impurities, and the mesh enclosure 500 is detachably disposed in the mesh enclosure 500, so that the mesh enclosure 500 is detached for cleaning.
Referring to fig. 2, 3 and 6, in one embodiment, the waste valve 10 may be a solenoid valve, a throttle valve or a throttle plug. By way of example, and with reference to the solenoid valve, the waste valve 10 has a throttling mode and a flushing mode, and the valve core assembly 103 is movably disposed in the valve body 100 to switch between the throttling mode and the flushing mode. When the waste water valve 10 is an electromagnetic valve, the mode switching of the waste water valve 10 can be controlled only by switching on and off electricity, the structure and the principle are simple, and the operation is easy. Of course, in other embodiments, the waste valve 10 may have other configurations, for example, the waste valve 10 may include a motor that drives the valve core assembly 103 to reciprocate to open or close the outlet chamber 140, thereby switching the waste valve 10 between the throttling mode and the flushing mode.
When the waste water valve 10 is in the throttling mode, the valve body 100 is further provided with a water sealing opening 170, at this time, the valve core assembly 103 blocks the water sealing opening 170, at this time, the water inlet cavity 130 and the water outlet cavity 140 are communicated through the throttling flow channel 200, waste water enters the water inlet cavity 130 through the water inlet 110, and then flows to the water outlet 120 through the throttling flow channel 200 and is discharged.
When the waste valve 10 is in the flushing mode, the valve core assembly 103 opens the water sealing port 170, and at the moment, the water inlet cavity 130 and the water outlet cavity 140 are not only communicated through the throttling flow channel 200, but also directly communicated through the water sealing port 170. The direct communication means that water in the water inlet chamber 130 directly enters the water outlet chamber 140 without passing through the throttling flow channel 200, and because the cross-sectional area of the water sealing port 170 is much larger than that of the throttling flow channel 200, under the action of water pressure, waste water directly flows from the water inlet chamber 130 into the water outlet chamber 140 through the water sealing port 170 and is then discharged through the water outlet 120.
In one embodiment, when the valve core assembly 103 opens the water outlet cavity 140, a first path passing through the throttle flow channel 200 is formed between the water inlet 110 and the water outlet 120, and a second path passing through the water inlet 110, the water inlet cavity 130, the water outlet cavity 140 and the water outlet 120 in sequence, and the length of the first path is greater than that of the second path.
Specifically, when the valve core assembly 103 opens the water outlet chamber 140, and the waste valve 10 is in the flushing mode, the water inlet chamber 130 and the water outlet chamber 140 are not only communicated through the throttling channel 200, but also directly communicated through the water sealing port 170. Under the action of water pressure, the waste water flows directly from the water inlet chamber 130 into the water outlet chamber 140 through the water sealing port 170 and then is discharged through the water outlet 120, and the path is the second path. When the valve core assembly 103 closes the water outlet cavity 140, the waste water valve 10 is in the throttling mode, and waste water enters the water inlet cavity 130 through the water inlet pipe, then flows to the water outlet pipe through the throttling flow channel 200 and is discharged, wherein the path is the first path. Since the first path is involved with the throttle flow path 200, the length of the first path is greater than the length of the second path.
The utility model discloses a waste water valve 10, the waste water valve 10 comprises a valve body 100 and a throttling flow channel 200, the valve body 100 is provided with a water inlet 110 and a water outlet 120; a throttle flow passage 200 disposed in the valve body 100 for communicating the water inlet 110 and the water outlet 120; here, there are two planes perpendicular to the extending direction of the throttle flow path 200, and the two planes have different cross-sectional areas or shapes on the throttle flow path 200. Therefore, the technical scheme of the utility model prevents the waste water valve 10 from being blocked by increasing the flow area of the throttling flow channel 200, then increases the on-way resistance by prolonging the flow path of the waste water, and in addition, changes the area or the shape of the cross section of the throttling flow channel 200 to bring extra local resistance, thereby controlling the waste water ratio. Therefore, the waste water valve 10 provided by the utility model is not easy to block, the waste water ratio can be controlled, and the anti-blocking effect of the waste water valve 10 is improved under the condition of throttling.
