Description

Water level control device for water tanks

The present invention relates to a water level control device, and more specifically, to control the inflow and outflow by using a float lifting in accordance with the water level in a non-powered manner, converting the mechanical lifting actuation force of the float into a rotational actuation force and straighten the rotational actuation force again The invention relates to a water level control device for a water storage tank capable of miniaturization, because the inlet valve is opened and closed by switching to motion.

In general, in the method of controlling the water level, a method of electrically controlling using a sensor and a mechanical method of a non-power source are variously known.

The electric method has a large level of water level control, and the valve also uses an electric valve, so the opening and closing force can be designed as needed. However, the manufacturing cost is high, which is a low cost device. The installation has a disadvantage in that it is difficult to apply, and since it has a control device, a sensor, and a driving device, a failure occurs frequently.

For example, the water storage tank of the household water purifier, the water storage tank of the toilet bowl, and other interior water storage tanks are urgently required for improvement because the expensive water level control device generates a lot of after-sales maintenance factor with the problem of price increase. have.

As in the above example, inexpensive apparatuses and facilities have adopted a mechanical level control device for cost reduction.

Representative of the mechanical water level control device consists of a float that detects the water level and a lever that is coupled to the float to generate a valve actuation force, a type consisting of an influent on / off valve linked to the lever, and a float and an influent on / off valve. There is a type in which a magnetic force acts on the valve as a pair of magnets face each other by embedding a pair of magnets between the valves.

Korean Utility Model Registration No. 246081 is known as the former type.

It consists of a water storage main tank and an auxiliary tank to form a float coupled to the first and second levers in the auxiliary tank, and the diaphragm which is connected to the valve shaft by lifting the valve shaft through a second lever whose actuation force functions as a lever. It is made by configuring the valve to block the influent through.

According to this conventional technology, as described above, the dynamic force difference is severely generated depending on the length of the lever, so that the length of the second lever, which is the lever, needs to be long to provide a strong operating pressure to the valve through the lever. It is very unreasonable to miniaturize the device, and the small length of the lever leads to the inability to withstand the inlet pressure, resulting in water leakage at the valve and difficulty in adjusting the level at the proper level, resulting in malfunctions exceeding the reservoir tank.

In addition, since the lever is configured as a lever of the lever and the link section, when the operating pressure is excessive, the transmission point of the force is biased, which often leads to the damage of the lever or the parts supporting them.

In the latter case, it is known as Korean Utility Model Application No. 94-13418 and Publication No. 99-75547, and constitutes a valve to block inflow water with a diaphragm, embeds a magnet in the lower part of the valve, and lifts the valve in the lifting port. It is made to control the water level by opening and closing the inflow water through the action of closing the valve by acting to close the valve by acting to retract the magnet by the magnet of the same polarity as the magnet.

However, this conventional technology has a disadvantage in that it is very difficult to maintain the quality when the magnet is difficult to maintain the correct product quality due to its characteristics, and when the level control device is completed, the deviation of the adjustment level is severely generated. The magnetic force is not proportional to the distance between the opposing magnets due to its characteristics, and thus the disadvantage is that it cannot accurately reflect the level at which the ball operates.

In addition, all the techniques of the above-described method is that when the hydraulic pressure in the opposite direction acts on the ball, the ball can be easily pushed out by this water pressure, or if the ball is strongly repulsed, mechanical damage may be caused, so that the valve closing force is not firm. there is a problem.

The present invention has been made to solve the disadvantages of the prior art as described above has the following object.

The present invention is to provide a water level control device for a storage tank made to deliver the operating force of the mouth through a combination of gear group, the transmission torque is increased to improve the valve closing force, so that the airtight maintenance is completed.

The present invention is to provide a water level control device for a water tank useful for miniaturization because the operating force is sheared through the gear group to obtain a large operating force even without forming a long like a lever.

The present invention is to provide a water level control device for a storage tank made of a variety to be installed directly inside the storage tank or in the case of drinking water storage tank according to the purpose.

The present invention is to provide a water level control device for the reservoir tank made of a dual configuration to operate the inlet opening and closing valve independently to ensure a leak even if the inlet pressure is high.

The present invention made to achieve the above object is a storage tank for storing water, and a level tank for detecting the level of the water level built into or external to the storage tank, and the number of lifting in the level tank and the lifting power of the float A gear box with a gear group and a cam gear that opens and closes the valve at the end of the gear group to pressurize and open the valve so that the linear motion of the ball is changed to the rotary motion and the rotational motion is converted to the linear motion to open and close the valve.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the technical configuration of the present invention.

Storage tank (1) for storing water, a level tank (2) mounted inside or outside the storage tank to communicate with the water, a float 24 for lifting in accordance with the water level in the level tank, inflow water by the operating force of the float A water level control device for a water storage tank comprising a valve for opening and closing a gear, the gear including a gear group formed by forming a cam in a plurality of gears and end gears for converting the linear motion force of a buoy embedded in the level tank into a rotational motion force. It is made to transmit with a working force to the valve which opens and closes an inflow water inlet through a box and a gear with a cam of the gear group end which converts rotational motion force by a gear group into linear motion.

The gear group embedded in the gear box 3 includes a first sector gear 30 integrally formed with the link 31, and a second sector integrally formed with the first pinion 32 and the pinion engaged with the first pinion. The gear 34, the second pinion 36 meshing with the second sector gear, the cam gear 38 meshing with the second pinion as the end gear and providing the projection 39 on one side of the gear are sequentially engaged with each other. It is made by coupling the rod (26) of the mouth (24) to the link (31), fixedly coupled to the lower portion of the cover 22 for closing the upper portion of the level tank (2), The projection 39 of the cam gear 38 is coupled to contact the operating shaft of the valve.

The configuration as an embodiment in which the present invention is specifically applied to a storage tank will be described in more detail with reference to FIGS. 1 and 2.

As described above, the linear motion of the buoy is transmitted to the valve by a gear group built into the gear box 3, and the valve 4 is influent formed integrally with the cover 22 of the level tank 2. A packing 44 is inserted into the tip of a valve seat 42 having a radial protrusion to open and close the inlet 46. The cam gear 38 protrusion 39, which is the end gear, and the end of the valve seat 42 are interviewed. And the level tank 2 is fixedly coupled to the water level control level position inside the reservoir tank 1.

The present invention made as described above is made to replenish the reservoir tank 1 along the open valve (4) when the water is introduced through the inlet water inlet (46).

As the continuous inflow of water occurs, the water level is changed, and the buoy 24 is raised as the level inside the reservoir tank approaches the limit level through the through-hole 210 of the lower level tank 2 coupled to the constant water level. At this time, as the first sector gear is rotated by the link 31 of the first sector gear 30 coupled to the hinge 320, the first pinion 32 and the second sector gear 34 having the pinion and the first pinion are engaged. The two pinions 36 and the cam gear 38 are driven together so that the protrusions 39 push the valve seat 42 so that the packing 44 blocks the influent.

At this time, the valve 4 is able to withstand a much stronger hydraulic pressure than the conventional method using a lever by a number of gears engaged with each other, so that the air tightness is enhanced even if the pressure in the reverse direction is applied.

As the water level in the water storage tank 1 is used through the water outlet 10, if the water level is lowered, the float 24 moves downward while the water level is lowered, thus linking 31 hinged to the rod 26. Is rotated downward while the gear groups rotate in the reverse direction. Accordingly, the cam gear 38, which is the end gear, is also reversely rotated, and the pressure applied to the valve seat 42 is removed by the projection 39. As the valve 4 is opened by the elasticity of 44, water is introduced into the reservoir tank, and the water level of the reservoir tank is controlled while repeatedly replenishing and discharging up to an appropriate level.

The following looks at a modified embodiment of the present invention.

As shown in FIGS. 3 to 4, the water level control apparatus for the storage tank of the present invention does not form an inlet inlet in an upper direction of the reservoir tank, and may provide an inlet inlet in the side direction of the reservoir tank 1 according to the surrounding structure. It may be.

This is achieved by configuring the position of the cam gear 38, which is the end gear, in the lower part of the gear box 3 from the embodiment shown in FIGS. 1 and 2, and the inflow water inlet 46 is also provided on the horizontal coaxial line of the cam gear. It is done.

According to this modified embodiment, if the water level level control process of the water storage tank is the same as described above, the inflow water inlet may be provided on the side of the water storage tank according to the peripheral configuration of the water storage tank, thereby increasing the variability of the product design.

Next, another embodiment of the present invention shown in FIGS. 5 to 8 will be described.

This is an improvement in the valve structure to be suitable for the purpose of adjusting the level of water while preventing secondary contamination of the influent, such as water purifier.

The level tank 2a has a port 28 coupled to the outside of the reservoir tank 1 to communicate with the reservoir tank on one side thereof so as to detect the water level, and has a buckle 24 and a gear box 3 built therein. The valve 4a integrally forms a sealing ring 472 between the inflow inlet 460 and the inflow outlet 470, and a diaphragm 450 and a sealing cover 440 that open and close the sealing ring below the sealing ring. The valve housing 400 formed by sequentially inserting the diaphragm elevating rod 430 is screwed to the cover 22a so that the lower end of the rod 430 is in contact with the cam gear 38 of the gearbox 3.

The diaphragm 450 is formed by forming a plurality of through holes 452 through concentric circles deviating from the diameter of the sealing ring 472 to the center through hole 454 and the outside of the center through hole.

According to the present embodiment made as described above, as shown in FIG. 8, when the water is introduced through the influent inlet 460 when the coupling is installed to detect the level of the water level as the port 28 at a predetermined height of the water storage tank 1. 6, the sealing ring 472 and the diaphragm 450 of the valve housing 400 are separated from each other so that the inflow water flows from the inlet to the outlet.

When the water level of the storage tank is increased in the process of storing as described above and reaches the predetermined level, the buckle 24 is raised and the projections of the cam gear 38 interlock with the buckle and the gear group in the same manner as the driving of the gear box 3 described above. The 39 pushes up the rod 430 of the valve 4a, thereby raising the sealing cover 440 and the diaphragm 450 to seal the sealing ring 472 of the valve housing 400, thereby blocking the inflow of water. The valve is closed, and at the same time, the water pressure is continuously filled while water is filled in the space between the diaphragm lower portion and the sealing cover 440 via the through hole 452 of the diaphragm 450 in addition to the action of the diaphragm and the rod. As the diaphragm 450 is expanded, a pressure for secondaryly pressurizing the diaphragm is generated to increase the closing force of the valve, thereby easily blocking the water flowing into the high water pressure. Is (see Fig. 7).

As described above, the valve tightly closed by the mechanical actuation force of the cam gear and the secondary pressure of the inflow water pressure is the lower portion of the water storage tank 1 when the float 24 moves downward while the cam gear 38 moves. Since the closing force applied to the rod 430 by reverse rotation is removed and the diaphragm 450 moves downward by the inflow water pressure transmitted from the inflow inlet 460, the valve is opened by being spaced apart from the sealing ring 472. Water movement takes place.

At this time, the water pressure acting between the lower portion of the diaphragm 450 and the sealing cover 440 is discharged through the central through hole 454 and the pressure drops to prepare for the next operation.

FIG. 9 is a modified embodiment of the invention of FIG. 5, in which the level tank is formed to extend in the lateral direction to form a level tank 2b and a cover 22b, and has a plurality of rods 26b in the level tank 2b. A plurality of gearboxes 3 are hingedly coupled to each rod 26b to drive, and a plurality of gearboxes 3b are formed in the upper portion of the cover 22b. It can also be achieved by connecting as a connecting pipe 50 to form a plurality of valves on the water channel.

Meanwhile, FIG. 10 shows another modification of the invention of FIG. 5.

This is to form a plurality of gear box (3) in the longitudinal direction as compared to the design of Figure 9 coupled to the plurality of gear box (3) in the longitudinal tank (2c) in the longitudinal direction, each valve to the cam gear of each gear box 4a is combined to connect the water outlet to the connection pipe 52 to form a plurality of valves on the water passage.

The plurality of valves may be operated with a parallax, respectively, and the parallax operation of the valve can be easily realized in the case of the difference in the insertion position angle of the cam gear. That is, the end embedded in both gear boxes 3 If the angle of projection of cam gear 38 is assembled and installed at a mutually shifted angle, one of the protrusions closes the valve first, and the other side of the cams closes the valve with time difference, and it also has a time difference when opening. Alternatively, the cam gear insertion angle may be the same, and a plurality of rod lengths provided in the float may be formed differently or may be provided with a position difference between the hinge holes.

According to the above embodiments, the closing of the valve by the float and the gear group is performed by the plurality of valves, thereby reducing the risk of water leakage. When the valve is opened and closed at a time difference, the valve is effectively closed even at a high inflow pressure. It is possible.

The present invention as described in detail above has the effect that the transmission torque is increased through the combination of the gear group, the transmission torque is increased, the valve closing force is improved, so that the airtight maintenance is completed, shearing the operating force through the gear group Therefore, it is possible to obtain a large operating force without forming long like a lever, so it is useful for miniaturization, and depending on the use, it can be installed directly inside the storage tank or in the case of a drinking water storage tank to be installed outside. There is an effect that the application is made wide, it is a very practical design having a number of excellent effects such as reliably prevent the leakage even if the inlet water pressure is high by configuring the inlet opening and closing valve to act independently.
