The present invention relates to a timer switching valve and a hydraulic regenerative water softener having the same, and more particularly, comprising a valve upper plate and a valve lower plate which are in close contact with each other up and down, and according to the rotation angle of the valve upper plate. The present invention relates to a timer switching valve configured to be changed and a hydraulic regenerative water softener having the same.

Currently, water softeners installed in homes or offices have a basic function of chemically converting hard water ions contained in tap water into softened water.

In general, tap water (hard water) contains a large amount of chlorine used in the purification process, and also contains various heavy metals (ions) such as iron, zinc, lead, and mercury, which are harmful to humans due to deteriorated pipes and water pollution. . Such tap water is not fatal to the human body, but when used as it is when washing the skin, the metal ions contained in the water and the fatty acids of the soap are combined to make a metallic foreign substance. It causes skin diseases or accelerates aging of the skin.

Therefore, in order to prevent this, tap water is passed through a Na + type strong acid cation exchange resin, and a softener is developed to exchange the hardness components Ca2 + and Mg2 + with Na + in ionic resin to make soft water, which is used for cleaning. have.

The water softener has the principle of softening by replacing Ca2 + and Mg2 + contained in hard water with Na +. To this end, the water softener includes a resin tank containing an ion exchange resin of a special high molecular compound containing Na + as an essential component. In this case, it contains a regeneration vessel in which a regeneration material or an ion exchange resin regenerator such as salt (NaCl) that generates Na + is incorporated.

That is, the water softener generates soft water by continuously passing hard water into the resin tank and contacting the ion exchange resin in a state where a large number of fine ball-shaped ion exchange resins are stored in the resin tank. The Na + component is substantially reduced by continuous contact with the hard water, so that the regenerated water of the NaCl component is flowed from the regeneration tank to the resin tank to preserve it.

In order to prevent leakage of water contained therein, a separate watertight member (not shown) is provided between the valve housing 210 and the upper cover 270. May be preferred.

Hereinafter, with reference to FIG. 4, the structure which reduces the load which acts between the valve upper plate 250 and the valve lower plate 240 by the water pressure in the valve housing 210 is demonstrated. The soft water hole 241, the raw water hole 242, and the regeneration hole 243 of the valve lower plate 240 maintain a structure protruding upward from the upper end of the valve lower plate 240 by a valve step 245. The valve step 245 means a separation distance between the valve upper plate 250 and the valve lower plate 240, and the raw water introduced into the valve housing 210 flows in between the valve upper and lower plates 240 and 250 to reduce the load.

Since the frictional force on the valve upper plate 250 is greatly canceled through the action of the force as described above can be driven by providing a minimum rotational force through the valve shaft 290.

Changing the flow path in the timer changeover valve 200

Hereinafter, the flow path change state in the timer switching valve 200 due to the relative arrangement between the valve upper plate 250 and the valve lower plate 240 will be described with reference to FIGS. 5 to 8.

First, the softening process for the supplied raw water will be described with reference to FIG. 5.

An inlet port 252 of the valve upper plate 250 is disposed on the soft water hole 241 of the valve lower plate 240. The above process is made possible by rotating the valve upper plate 250 which is interlocked with the valve shaft 290 and the connector 260. In this state, the raw water hole 242 and the regeneration hole 243 of the valve lower plate 240 are blocked, and the flow of raw water is stopped.

The flow of water in soft water is as follows. Where-is defined as an indication of the flow of water.

Water inlet (10)-Raw inlet flow path (110)-Valve housing (210)-Inlet port (252)-Water softening hole (241)-Soft water outlet (211)-Filter inlet channel (310) )-Filter section (300)-Resin tank section (500)-Accumulation flowmeter (600)-Outflow passage (620)

Next, a process of supplying the supplied raw water without the training process will be described with reference to FIG. 6. An inlet port 252 of the valve upper plate 250 is disposed on the raw water hole 242 of the valve lower plate 240. The above process is made possible by rotating the valve shaft 290 in a clockwise or counterclockwise direction. In this state, the soft water hole 241 and the regeneration hole 243 of the valve lower plate 240 are blocked, and the flow to the resin tank 500 and the regeneration cylinder 400 is stopped.

The water flow in the raw water supply state is as follows.

Water outlet (10)-Raw import flow path (110)-Valve housing (210)-Intake port (252)-Sea flow hole (242)-Raw water outlet (212)-Outflow flow path (620)

Next, a process of regeneration using raw water supplied with reference to FIGS. 7 and 8 will be described.

In this state, it is possible to set the valve upper plate 250 to rotate in the clockwise direction for a preset regeneration time using the timer 230. The play time may be set by a timer spring built in the timer 230. In the present invention, for example, the force of the timer spring is adjusted to set the play time to 20 minutes. The restoring force of the timer spring is transmitted to the valve upper plate 250 through the first gear 232 and the second gear 292. In this process, the first and second teeth 234 and 294 formed on the outer circumference of the gears 232 and 292 are formed. This meshes with each other to ensure accurate rotation. Referring to FIG. 8, when the rotation driving by the timer 230 is completed, the inlet port 252 of the valve upper plate 250 passes through the other end of the regeneration hole 243 between the regeneration hole 243 and the softening hole 241. Located in space

The flow of water in the regeneration state is as follows.

Water outlet (10)-Raw import channel (110)-Valve housing (210)-Inlet port (252)-Regeneration hole (241)-Regeneration water outlet (213)-Regeneration channel (410) )-Regeneration container (400)-Resin tank distribution passage (520)-Resin tank unit (500)-Resin tank discharge passage (530)-Outflow passage (620)

Regeneration operation process of the water softener 1000 by the timer switching valve 200

When the exchange cycle of the ion resin is displayed on the total flow meter 600 while the training process for the raw water supplied through the resin tank 500 is performed, the user starts the regeneration process by rotating the valve shaft 290. The valve shaft 290 is rotated counterclockwise for the regeneration process so that the first tooth 234 of the first gear 232 and the second tooth 294 of the second gear 292 are engaged with each other. The second tooth shape 294 is divided into a first point 295 where the first gear 232 and the second gear 292 are first engaged, and a second point 296 where the engagement ends.

In the counterclockwise rotation of the first gear 232, the timer spring inside the timer 230 is wound while the second gear 232 is rotated clockwise from the first point 295. Thereafter, the rotation of the valve shaft 290 is stopped before passing through the second point 296. The above process may be referred to as a previous step for regeneration. The valve upper plate 250 may be operated by rotating the first gear 232 and the second gear 292 according to the nature of the wound timer spring. A constant rotation drive is made on 240.

While the inlet port 252 of the valve upper plate 250 passes through the regeneration hole 243 of the valve lower plate 240, a continuous regeneration operation is performed, and the inlet port 252 is no longer positioned on the regeneration hole 243. If not, since the inflow of raw water through the regeneration hole 243 is blocked, the regeneration process is terminated.

As described above, according to the present invention, the regeneration process is uniformly maintained for a predetermined time by using the timer switching valve 200, and the valve step 245 is offset to offset the load acting between the upper and lower valve plates 240 and 250. In driving the regeneration process, the driving force within the timer switching valve 200 is smoothly made. In addition, it is possible to reduce the volume of the valve housing by improving the shape of the through-holes formed in the valve upper plate 250 and the lower plate 240, and to minimize unnecessary flow reduction in the process of raw water flow in the valve housing.

While preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments. That is, those skilled in the art to which the present invention pertains can make many changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications are possible.
