The present invention relates to an integrated pressure reducing valve for a softener, and more particularly, by feeding the raw water introduced from the outside into a soft water tank filled with ion exchange resin, the soft water is softened and discharged. The present invention relates to an integrated pressure reducing valve for a water softener capable of measuring pressure inflow and temperature while supplying water to a soft water tank.

The daily water used in our daily life can be divided into soft water and hard water, and soft water such as distilled water or rain water, commonly referred to as sweet water, is hydrogen (H ₂ ) and oxygen (O ₂ ). Relatively pure and low hardness. On the other hand, hard water such as groundwater and tap water, called hard water, contains calcium ions (Ca ²⁺ ) and magnesium ions (Mg ²⁺ ), which have a high hardness. It combines with fatty acids to produce metallic foreign substances or acts as a cause of skin diseases such as promoting skin aging and atopic dermatitis.

In particular, tap water currently supplied to most households includes iron (Fe) and copper (Cu) due to hard water components such as calcium ions and magnesium ions, as well as chlorine (Cl) used during the purification process, and environmental pollution and the transport process through old pipes. ) It contains a lot of harmful heavy metals such as tin (Sn), zinc (Zn), and mercury (Hg), and in order to obtain higher quality living water, it removes hard water from tap water and converts it into soft water. Water softners have been introduced to remove ions.

Such water softeners are currently widely used in homes and businesses, and basically have a principle of softening by substituting light water components of calcium ions and magnesium ions contained in raw water such as tap water with sodium ions (Na ⁺ ), which are harmless to the human body. In this case, hard water, such as tap water flowing into the water softener, is referred to as raw water for convenience, which will be consistently used throughout the present specification with the same meaning.

More specifically, Figure 1 is a schematic block diagram showing a general water softener (2), in particular showing a structure that can obtain the cold / hot water from the cold / hot raw water.

As shown in the drawing, a general water softener (2) is an essential component of the cold / warm soft water tanks (12, 14) filled with ion exchange resins of special high molecular compounds containing small swelling and sodium ions. The cold / hot raw water supplied through the () is converted into soft water as calcium and magnesium ions in the water are replaced by sodium during the process of passing through these cold / hot soft water tanks (12, 14), respectively, and then the discharge pipe (18). It is discharged to the outside through.

On the other hand, sodium ions contained in the ion exchange resin in the cold / hot water tanks (12, 14) is gradually exhausted over time, so periodic regeneration is required. Cold / hot regeneration tanks 22 and 24 filled with ion exchange resin regeneration materials that discharge sodium ions when they are dissolved are respectively provided to correspond to the cold and hot water tanks 12 and 14.

In this case, the supply pipe 16 is provided with a switching valve 26 to guide cold / hot raw water introduced from the outside into the cold / hot water tanks 12 and 14 or the cold / hot regeneration tanks 22 and 24. In the former case, cold / hot soft water is discharged from the cold / hot soft water tanks 12 and 14, respectively. In the latter case, regeneration water such as salt water containing sodium ions from the cold / hot regeneration tanks 22 and 24, respectively, is discharged. As it is generated and supplied to each of the cold / hot water tanks 12 and 14, the regeneration wastewater is discharged to the outside after regenerating the respective ion exchange resins.

At this time, the discharge pipe 18 is provided with an intermittent valve 28 for controlling the discharge of cold / hot soft water or regeneration waste water, which is usually replaced by a power outlet.

In addition, in recent years, various additional functions have been added to facilitate the use of the water softener (2). For example, a plurality of cold / hot soft water tanks (12, 14) are provided, respectively, to provide more detailed temperature training. This function is provided to the user or the regeneration time of the ion exchange resin is automatically recognized based on the amount of water used. To this end, the supply pipe 16 of the water softener 2 is additionally provided with various detection means for the corresponding function, and interlocked with the switching valve 26. Specifically, a temperature sensing means such as a temperature sensor and / or a flow meter, etc. It can be a flow measurement means of.

On the other hand, the above-mentioned general water softener 2 does not have its own pressure regulating means such as a pump, so that soft water is discharged depending on the water pressure of raw water introduced from the outside, which causes some problems when the water pressure of the raw water is too large or uneven. have.

That is, when the water pressure of the raw water introduced from the outside is larger than necessary, the ion exchange resin of the cold / hot water tanks 12 and 14 and the regeneration material of the cold / hot regeneration tanks 22 and 24 may be unnecessarily exhausted. In addition, when the water pressure of the raw water is uneven, a strong pulsation phenomenon such as a water hammer may appear inside the water softener 2, which may act as a cause of failure.

For this purpose, a pressure reducing valve called a pressure reducing valve may be provided in the supply pipe 16. In addition, if a detecting means such as a temperature sensor and / or a flow meter as described above are separately installed, the configuration of the water softener is more complicated than necessary. In this case, there is a high possibility of malfunction and a disadvantage of increasing the size of the device and the installation area.

Accordingly, the present invention has been made to solve the above problems, it is possible to easily and accurately detect the amount and temperature of the raw water supplied to the soft water tank or the regeneration tank, and the soft water can be supplied to each by constantly reducing the inlet pressure of the raw water It is an object of the present invention to provide an integrated pressure reducing valve. Still another object of the present invention is to provide an integrated pressure reducing valve for a water softener having all of the above functions and having a small size, which can be freely used even in a small installation area in the water softener.

A diaphragm defining a vehicle side, a valve disc connected to the diaphragm and a stem to cover or open and open the relief hole at the primary side, and first and second coil springs interposed at a lower end of the valve disc and an upper end of the diaphragm, respectively. Decompression means comprising a; A flow rate measurement comprising a fixed screw installed in the water supply pipe so that the raw water rotates, a rotating body mounted inside the fixed screw and rotating in one direction according to the raw water inflow, and a counter for counting the number of revolutions of the rotating body; Means; It provides an integrated pressure reducing valve for a water softener comprising a temperature sensing means of a temperature sensor inserted into the water outlet pipe sideways.

At this time, the rotating body is a cylindrical guide frame which is arranged along the longitudinal direction of the inlet pipe and the end of the rotary screw and the inner side of the rotating screw attached to the at least one magnet eccentrically in a state that the rotation axis is aligned with the center of the inlet pipe And the counter includes a reed switch fixedly installed at one side of the water supply pipe and generating an electrical signal according to proximity to the magnet, and a counting circuit for counting whether the electrical signal is generated. .

In addition, the through-hole communicating with the discharge pipe is formed on the bottom surface in the state formed in the bottom surface; characterized in that it further comprises a fitting end projecting in the tube shape so as to be fixed, integrally formed on one side of the housing The water softener further comprises a bracket fixedly fastened to a predetermined position, wherein the water softener further includes at least one regeneration tank filled with regeneration material of the ion exchange resin in a state connected to the water softener, and integrated with the water softener. Pressure reducing valve is characterized in that for supplying the raw water to the soft water tank or the regeneration cylinder, with reference to the accompanying drawings will be described in more detail the present invention.

2 is a perspective view showing an integrated pressure reducing valve for a water softener according to the present invention, in which a pressure reducing means 70, a flow rate measuring means 60, and a temperature sensing means 90 are respectively installed into a casing 50. .

For each of them, first, the casing 50 may be divided into a housing 52 in the center, an inlet pipe 54 protruding outward therefrom, and an outlet pipe 56 through which the introduced raw water is discharged. A predetermined buffer area is defined in the housing 52 and communicates with the inlet pipe 54 and the outlet pipe 56, respectively.

Therefore, the inlet pipe 54 is connected to a general household power outlet, and the outlet pipe 56 is connected to a regeneration tank filled with regeneration material such as salt or a soft water tank filled with an ion exchange resin through a switching valve of a softener. By feeding the raw water, such as tap water into the soft water tank or the regeneration tank, the temperature and inflow of the raw water is measured and the pressure is reduced to a constant pressure.

To this end, the casing 50, more precisely, the inlet pipe 54, the flow rate measuring means 60, the housing 52, the decompression means 70, and the outlet pipe 56 are provided with temperature sensing means 90, respectively. 2, which is an exploded perspective view and FIG. 4 which is a sectional view, are demonstrated together with FIG.

First, the flow rate measuring means 60 installed in the inlet pipe 54 has a fixed screw 62 fixedly installed in the inlet pipe 54, a rotating body 64 mounted inside thereof, and a rotation speed of the rotating body 64. It includes a counter that counts, the double fixing screw 62 is fixedly biased to the end of the inlet pipe 54 to rotate the raw water flowing in from the outside in one direction, the rotating body 64 is the center of the inlet pipe 54 Cylindrical guides which are mounted along the inner longitudinal direction of the inlet pipe 54 so as to rim the inner end of the rotation screw 65 and the distal end thereof at which one or more magnets 67 are eccentrically attached in a state where the rotation axis is coincident with the shaft. Frame 66.

In addition, the counter is installed through one side of the inlet pipe 54 to generate an electrical signal through proximity to the magnetic material, and although not shown, the number of electrical signals generated by the reed switch 68 is not shown. Including a predetermined counting circuit for counting, the reed switch 68 is fixed to the molding 69 or the like in the state passing through one side of the inlet pipe 54.

Therefore, the raw water introduced into the water inlet pipe 54 is helically rotated while passing through the fixing screw 62 to rotate the rotating body 64 in one direction, whereby at least one magnet eccentrically attached to the rotating body 64 ( 67) generates an electrical signal as far as or close to the reed switch 68, and the counting circuit counts the number of times.

Therefore, the raw water inflow can be known through the counting results.

Next, the decompression means 70 is placed in the buffer area in the housing 52. For this purpose, the pressure reducing means 70 is connected to the water inlet pipe 54 across the housing 52 with the relief hole 72a penetrating therethrough. Diaphragm defining the sealed tertiary side 70c at the top of the partition wall 72 which is divided into the primary side 70a and the middle secondary side 70b in communication with the water outlet pipe 56 and the upper side thereof. 76).

In addition, the primary side (70a) is provided with a disk-shaped valve disk 74 for opening and closing the relief hole (72a) in accordance with the distance to or near the partition wall 72 is connected to the diaphragm 76 and the stamp (78) Interlocked with the first coil spring 80 at the lower end of the inner valve disk 74 of the primary side 70a and the second coil spring 82 at the upper end of the diaphragm 76 of the tertiary side 70c. do.

At this time, if no external pressure is applied, the valve disk 74 is spaced apart from the bottom of the partition 72 to maintain the relief hole 72a in an open state. The raw water introduced to the primary side 70a is delivered to the secondary side 70b through the relief hole 72a and then supplied to the soft water tank or the regeneration tank through the discharge pipe 56.

On the other hand, when the pressure of the raw water flowing into the primary side 70a is greater than or equal to the critical pressure of the diaphragm 76, the pressure of the secondary side 70b rises, thereby lifting the diaphragm 76 upwards, and thus the stamp 78 The valve disks 74 connected to each other rise together to close the relief holes 72a, and thus the elasticity of the first and second coil springs 82 interposed between the diaphragm 76 and the upper and lower ends of the valve disk 74, respectively. As a result, the pressure of the raw water discharged to the outlet pipe 56 is kept constant.

In this case, since there is a possibility of contamination when external raw water comes into contact with the first coil spring 80, a trap groove 84 recessed into the bottom surface may be formed in the primary side 70a of the buffer area, and The lower end of the disk 74 may extend to guide the end 86 of the guide end 86 is received into the trap groove 84, the first coil spring 80 into the guide end 86 and the trap groove 84 ) Is advantageously interposed. And it is preferable that the at least one O-ring 88 surrounding the outer end of the guide end 86 is in close contact with the trap groove 84 side can maintain the airtight.

Lastly, the temperature sensing means 90 may be a temperature sensor 92 or the like. For this purpose, a tube-shaped fitting end 94 protrudes from one side of the outlet pipe 56 to which the temperature sensor 92 may be fitted. The inner bottom surface thereof has a through hole 96 in communication with the water outlet tube 56.

Therefore, by inserting the temperature sensor 92 into the fitting end 94, it is possible to detect the temperature of the raw water flowing through the outlet pipe 56 through the through-hole 96.

Summarizing the operation of the integrated pressure reducing valve of the water softener according to the present invention described above, the external raw water introduced into the first inlet pipe 54 is spirally rotated in one direction while passing through the fixing screw 62, by the rotational force thereof The rotating body 64 is rotated. In this process, a counter composed of a reed switch 68 and a counting circuit counts the rotation speed of the rotating body 64 to detect the raw water inflow amount, and then the raw water flows into the primary side 70a of the buffer area.

At this time, when the pressure of the raw water introduced to the primary side 70a is less than a predetermined value as described above, the raw water is maintained by opening the relief hole 72a by keeping the valve disc 74 separated from the partition 72. After being delivered to the secondary side 70b and discharged to the water outlet pipe 56, when the raw water pressure is greater than or equal to the critical pressure of the diaphragm 76, the stamp 78 receives the restoring force by the first and second coil springs 82. The diaphragm 76 and the valve disc 74 connected to each other are linked up and down to open and close the relief hole 72a. Thus, the raw water is discharged under a constant pressure through the discharge pipe 56.

In addition, the constant pressure-reduced raw water is supplied to the soft water tank or the regeneration tank through the water discharge pipe 56, and is inserted into the fitting end 94 on one side of the water discharge pipe 56 during the process to mediate the through hole 96. The temperature of the raw water can be measured by the temperature sensor 92 exposed inside the furnace outlet pipe 56.

Therefore, by installing the integrated pressure-reducing valve for the water softener in the water softener can be supplied to the soft water tank or regeneration tank by constantly depressurizing the raw water, it is possible to detect the inflow and temperature of the raw water during this process.

At this time, preferably, one side of the housing 52 may be integrally formed with a bracket 100 for fastening and fastening by using a screw or the like while supporting the entire casing 50, by using the integrated pressure reducing valve for a water softener according to the present invention. Can simply be fixed in the water softener.

The integrated pressure reducing valve for water softener according to the present invention described above is based on the function of constantly depressurizing the external raw water and then discharging it to the outside, wherein the inflow and temperature of the raw water can be detected during this process.

Therefore, by linking it with the switching valve to determine whether the water tank or the regeneration tank is introduced, the regeneration cycle of the ion exchange resin can be automatically determined based on the amount of raw water inflow. By maintaining a constant depressurization it is possible to maintain the pressure of the soft water discharged to the outside as well as to prevent the pulsation occurring in the softener can extend the life of the softener. In addition, there is an advantage that can prevent unnecessary exhaustion of the ion exchange resin and regeneration materials.

In addition, by sensing the temperature of the inlet source water has the advantage that can discharge the soft water of the optimum temperature according to the user's purpose, the integrated pressure reducing valve for water softener according to the present invention has the advantage of a simple structure and a small installation area.
