Description


  Brine valve

  
The present invention relates to a brine valve.

  
Brine valves are already known which consist essentially of a housing with an inlet and an outlet for brine which are connected to each other through a channel.

  
In the known embodiments, the housing consists of a hollow body in which two holes are provided, more specifically one which forms the inlet for brine and which is situated in a horizontal top side of the body and a second which forms the outlet for brine and which is generally in a vertical side wall of the body is provided.

  
In such known brine valves, the channel is formed by a central space in the body.

  
As is known, the hole forming the inlet for brine can be closed by a valve with two valves which are mutually connected by a rod extending through the aforementioned hole, so that one of the valves is located in the central space and allows the channel to drain. closing in a flow direction from the outlet to the inlet, while the other valve is outside the housing and allows closing the channel in a flow direction from the inlet to the outlet.

  
The aforementioned valve is hereby controlled on the basis of the liquid level in a pickle reservoir in which the pickle valve is arranged, by means of a float attached to the valve, in particular to the valve located outside the housing.

  
The operation of such a known brine valve is to suck in brine from the brine reservoir by creating a vacuum at the brine outlet.

  
By suctioning and draining brine through the outlet, the liquid level in the brine reservoir will drop to the moment that the float reaches the level at which the valve closes the inlet of the brine valve in a direction towards the outlet, so that no brine solution can be used anymore are sucked in.

  
In order to subsequently refill the brine valve, water is usually pumped in counterflow to the brine flow through the brine valve, the amount of water added being determined as a function of the amount of brine solution that will be sucked in a subsequent function.

  
It is noted that salt is provided in a solid state in a brine reservoir, this salt dissolving in the water in the brine reservoir to form a brine solution.

  
Because the salt in a solid state is at the bottom of the brine reservoir, the brine concentration in the water will initially decrease as a function of the level at which the water is located.

  
Moreover, this difference in brine concentration between the different water layers is further enhanced by the fact that a saturated brine solution has a greater density than an unsaturated brine solution, so that there is relatively little mixing between the different water layers in a brine reservoir.

  
A drawback of the known brine valves is that the inlet for brine is at a relatively high level in the brine reservoir, wherein the brine solution at that level is still unsaturated in many cases when brine is sucked in.

  
Moreover, the brine solution, which is located at a level below the inlet for brine, always remains unused in the brine reservoir, while this saturated brine solution does not, or only to a very limited extent, mix with freshly supplied water.

  
The disadvantage of this is that the brine concentration of the aspirated solution is unknown, which makes it relatively difficult to determine the amount of solution required for regenerating an ion exchanger, for example.

  
Yet another drawback of the known pickle valves is that the float is in the pickle solution and from time to time, when pickle solution is sucked in, it comes to dry for a while, whereby salt crystals form on the surface of the float, which have an influence on the mass of the float that is thereby disrupted.

  
Another drawback of the known pickle devices is that, when refilling the pickle reservoir, water flows through the pickle outlet to the inlet through the central space in the housing, which also includes the valve that can close the pickle inlet in a sense from the central chamber to the brine reservoir.

  
A problem with the known brine valves is that this valve is closed by the inflowing water before the liquid level in the brine reservoir has reached a desired level, so that, in a subsequent regeneration with brine solution from the brine reservoir, relatively little brine solution can be sucked in, so that desired regeneration cannot be completed.

  
The object of the invention is to offer a solution to one or more of the aforementioned disadvantages.

  
To this end the invention relates to a pickle valve consisting essentially of a housing with an inlet and an outlet for pickle connected to each other by a channel in which a valve is arranged for closing a passage in the channel, characterized in that the inlet for brine at a level below the level of the aforementioned passage.

  
An advantage of the present invention is that the suction of brine can always take place at a relatively low level in the brine reservoir, whereby saturated brine solution can always be sucked in with a known brine concentration.

  
Another advantage is that the float is at a relatively high level with respect to the brine supply, whereby this float is at a level in the brine solution that is not always saturated and whereby the chance of salt crystals depositing on the float is relatively high. is small, so that the operation of the float remains accurate.

  
Moreover, the float is preferably located in the housing, at a level above the inlet for brine.

  
Such an embodiment offers the advantage that, when refilling the brine reservoir through the channel in the housing, the water around the float is relatively unsaturated and moreover does not or hardly mix with the saturated brine solution at the entrance of the brine valve, whereby any salt crystals on the brine valve be more easily dissolved in the water.

  
According to another aspect of the invention, the brine valve is provided with a housing which is at least partially double-walled, wherein a central space and a peripheral space are defined in the housing that are mutually connected via a passage and wherein the aforementioned outlet for brine is connected on the peripheral space.

  
An advantage of this embodiment is that when topping up the brine reservoir, the incoming water flow first flows into the peripheral space, before entering the central space, so that the chance of the valve provided in the aforementioned passage being relatively small is small. , closes.

  
With the insight to better demonstrate the characteristics of the present invention, a brine valve according to the invention is described below as an example without any limiting character with reference to the accompanying figures, in which: figure 1 shows a view of a brine valve according to the invention; figure 2 represents a view according to arrow F2 in figure 1; figure 3 represents a section according to line III-III in figure 2; figure 4 represents a section according to line IV-IV in figure 2; figures 5 and 6 show the same view as figure 4 but in different positions of the brine valve.

  
Figures 1 and 2 show a pickle valve 1 consisting of a housing 2 with an inlet 3 and an outlet 4 for pickle which are mutually connected by a channel 5.

  
As shown in Figures 3 and 4, the housing 2 in this case consists of three different parts 6, 7 and
8.

  
The first part 6 of the housing 2 here consists of a substantially cylindrical body in plastic with a casing 9 on which an end wall 10 is arranged at one end, which wall forms the top side of this body in the use condition of the brine valve 1.

  
A passage 11 is provided in the end wall 10 mentioned above.

  
Furthermore, different longitudinal ribs 12 are provided on the casing 9 of this body 6 and a passage 13 is provided in the casing 9 which forms the brine outlet 4.

  
The second part 7 of the housing 2 also consists of a cylindrical body which is provided with an end wall 14 at one end.

  
This part 7 of the housing 2, with its open side 15 facing upwards, is fixed in the aforementioned first part 6 of the housing with the aid of, for example, a clips 16.

  
It is noted that the open side 15 of this second part 7 is in the mounted state at a distance from the end wall 10 of the first part 6 of the housing 2, so that a passage 17 is created between this open side 15 and the end wall 10.

  
The above-described construction of the first and second parts 6 and 7 of the housing 2 results in a partial double-walled embodiment of the housing 2 which has a central space 18 which is bounded by the second part 7 and by the end wall 10 of the first part 6 of the housing, and which has a peripheral space 19 between the jackets of both aforementioned parts 6 and 7, wherein, according to the invention, the aforementioned brine outlet 13 connects to the peripheral space 19.

  
The third part 8 of the housing 2 in this case consists of a cylindrical body which, preferably, is closed at one end, in particular the upper end, by an end plate 20 and that with its open side 21 tensioning over the aforementioned ribs 12 is arranged on the outside of the first part 6.

  
Between the aforementioned ribs 12, the jacket 9 of the first part 6 of the housing 2 and the inside of the third part 8, a passage is hereby kept free which forms the pickle inlet 3 of the pickle valve 1.

  
It is noted that, according to the invention, this brine inlet 3 is located at a level below the level of the aforementioned passage 11 in the end wall 10 of the first part 6 of the housing.

  
With regard to the third part 8 of the housing 2, it is finally noted that at its upper end it is preferably provided with one or more holes 22.

  
The aforementioned channel 5 in the housing 2 is composed successively of the aforementioned passage which forms the inlet 3 for brine; the passage 11 in the end wall 10 of the first part 6 of the housing 2; the central space 18; and the peripheral space 19.

  
According to the invention, in the channel 5 a valve 23 is provided which consists of a rod 24 which is arranged through the passage 11 and which is provided at both ends with a valve 25, 26, which valves 25, 26 permit the aforementioned passage 11 to close.

  
Preferably a seal 27 is provided on both sides of the passage 11 in the end wall 10 which guarantees a good connection of the valves 25-26 to a peripheral wall 28 of the passage 11.

  
Furthermore, a float 29 is attached to the upper valve 25, which float consists of a hollow plastic body that can freely move up and down in the cylindrical body forming the third part 8 of the housing 2.

  
The operation of the brine valve according to the invention described above is simple and as follows.

  
In operating condition, the pickle valve 1 is arranged in a pickle reservoir that is not shown in the figures, in which a pickle solution is provided.

  
In a state prior to the suction of brine, the liquid level of the brine solution in the aforementioned reservoir is such that the float 29 is at a level at which the valve 23 is opened, as shown in Figure 5.

  
In the housing 2 of the brine valve 1, the liquid level is equal to, or almost equal to, the liquid level in the brine reservoir, because the above-mentioned holes in the third part 8 of the housing 2 are provided, through which the housing 2 and the brine reservoir must are considered as communicating vessels.

  
In the above-described state, when an underpressure is created at the brine outlet 4, the brine solution is drawn from the reservoir through the channel 5.

  
By sucking in brine, the liquid level in the brine reservoir will decrease, as will the position of the float 29.

  
When the float 29 reaches its lowest position, as shown in Figure 4, the valve 25 of the valve 23 closes the passage 11, whereby the supply of brine from the brine reservoir is stopped.

  
In order to fill back the brine reservoir, it is known to supply water through the channel 5 to the brine reservoir.

  
In the case of a brine valve 1 according to the invention, the water flows through the brine outlet 4 into the peripheral space 19, whereafter it flows via the passage 17 into the central space 18 of the brine valve 1.

  
The water in the central space 18 will hereby exert an upward pressure on the valve 25 of the valve 23, whereby this valve 23 is opened and the water can flow further to the brine reservoir.

  
In a normal state of use, the volume of water added to the brine reservoir is accurately determined and the supply will automatically stop in a state where the valve 23 is open.

  
If, accidentally, the water supply does not stop automatically, the reservoir will be filled further until the float 29 reaches its highest position, as shown in Figure 6.

  
In this highest position, the valve 26 closes the valve 23 in a flow direction from the outlet 4 to the inlet 3 for brine.

  
It is noted that the pickle valve 1 is preferably provided with means that allow it to be fastened in a pickle reservoir or the like, which means in the shown figures consist of a fixing ring 30 which can be arranged over the housing 2 and which is provided with two elastic protrusions 31, each of which extends on one side of the fastening ring and which differs slightly.

  
As is known, both protrusions 31 can be pushed towards each other and then placed, under the applied bias, in suitable locks, not shown in the figures and provided in the brine reservoir, for fixing the brine valve 1.

  
The present invention is by no means limited to the embodiment described above and shown in the figures, but a pickle valve according to the invention can be realized according to different variants without departing from the scope of the invention.
