Abstract

The present invention solves the problems of the float valve which is widely used at the same time, and relates to an automatic water level control device equipped with a float valve having a dual level control function.

Conventional float valves open water even when the water level is a little low, which causes the power to be lost when using a motor because the valve operates immediately due to natural evaporation of water or leaking a small amount of water from the pipe. There was a problem that the valve life is shortened due to frequent opening and closing of the valve. In addition, to overcome the conflicting forces of hydraulic pressure and buoyancy while using the product made of brass to maintain the buoyancy.

Therefore, the present invention has a structure that blocks the flow of water by internal water pressure, and by installing a spring on the valve case to open the valve after a certain amount of water is removed, thereby preventing frequent opening and closing of the valve and by using a synthetic resin instead of conventional brass It is free from contamination, low thermal conductivity, safe for freezing, and low in manufacturing cost. In addition, by adopting the method of filling the water or sand in the buoys can reduce the size of the buoys, attached to the function of the water level control so that consumers can arbitrarily control the desired water level.

Description

Automatic water level controller with float valve to regulate dual water level}

The present invention relates to an automatic water level control device installed in a water tank and the supply of water is stopped when the valve of the water supply pipe operates according to the water level in the tank and reaches a desired level.

Conventional technology has a structure in which the valve rises from the bottom using buoyancy, but in this case, the buoyancy and water pressure always have a conflicting force, so the water level varies depending on the water pressure, and the buoyancy is gathered in one place, and the entire buoyancy body is It had to be made of brass or stainless steel of high strength.

In addition, the conventional valve has a problem that frequent opening and closing of the valve because the valve is operated even if the water level is only slightly lower, there is a problem that a lot of power loss according to the use of the motor. In addition, in the past, to adjust the water level to bend the support to adjust, in this case, due to the buoyancy upside down due to the buoyancy side of the water overflow often occurs, the present invention was devised to solve this problem.

Therefore, in the present invention, by installing a spring on the valve door, the valve is opened after a certain amount of water is removed, thereby preventing the waste of power due to frequent opening and closing of the valve, and shortening the life of the valve, and using synthetic resin instead of brass. Its purpose is to provide economical automatic water level control device because it is not polluted, has low thermal conductivity, is safe for freezing waves, and has low manufacturing cost.

In order to achieve the above object, the present invention hinges and fixes the support on which one side of the water supply pipe is installed, and installs a valve in the water supply pipe to open and close the water supply pipe according to the rotation of the support. The valve opening is formed at the end of the support that is located inside the water supply pipe, but the valve is opened only when the water level is lowered below a certain level by installing a spring to prevent the valve from opening immediately when the float goes down by the water level. It is provided with an automatic water level control device having a.

Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

1A to 1C are schematic views showing an embodiment of the present invention, and the present invention has a support 6 fixed to a hinge 4 at one side of the water supply pipe 1, and the hinge 4 is It will act as the point of action of the lever.

In addition, one end of the support (6) is provided with a buckle (7), the other end of the support (6) inserted into the water supply pipe (1) valve opening (9) of a predetermined length so as to push the valve (2) Is formed.

In this invention, the weight of the floats 7 is made heavy by filling the floats 7 with water 8, and thus the support 6 is hinged 4 even though the water pressure in the water supply pipe 1 is high. It is desired to rotate downward (clockwise) to the center so that the valve opening and closing 9 works smoothly.

In addition, the present invention implements the double water level by installing the spring (3) in the valve opening (9), that is, the spring (3) is slightly pressed by the water pressure in Figure 1a and the valve (2) is kept closed do.

In this state, the water level is lowered due to external factors, that is, natural evaporation or water leaking from the pipe, etc. The valve 2 of the present invention is not easily opened due to the internal water pressure even if the water level is continuously lowered. As the water level is lowered, the buckle 7 is lowered and the support 6 is rotated about the hinge 4 so that the valve opening 9 is raised upward.

At this time, the spring 3 continues to be compressed so that the clearance with the valve case 9 gradually decreases, and when the water level continues to decrease, the valve case 9 eventually pushes the valve 2 (Fig. 1C). At this time, when the restoring force of the spring (3) is large or the water pressure is low, the valve (9) opens the valve (2) before it reaches the valve (2). In other words, the interval between the two levels is reduced.

When the valve (2) is open at this time, the internal water pressure does not work to lift the valve (2) up due to the restoring force of the spring (3) and the water is continuously released through this gap, even if the water level is high, the spring (3) It maintains the open state and the buckle (7) has a position similar to the water level due to the buoyancy, and finally to the closed state of Figure 1a, the water supply is stopped.

In addition, in the present invention, by installing the water level regulator 5 in the middle of the support 6 can be adjusted to the user desired level.

2a to 2c are views showing another embodiment of the present invention, the support 16 is installed on the support 16 between the water level controller 15 and the mouth 17, but the support 16 Hinge fixed so that the fixing section 20 is located at the lower portion of the, and the end of the fixing section 20 is to form a vertical piece interposed with the spring (13).

In this case, when the water level is lowered, the support 17 is rotated about the hinged portion while the buckle 17 is lowered to compress the spring 13 (FIG. 2B).

After that, if the buoy 17 is continuously lowered, the spring 13 is rotated about the hinge 14 fixed to the water supply pipe 11 in the compressed state to open the valve 12.

Therefore, the same effects as described in the embodiment of the present invention can be obtained.

In addition, in order to solve the problem when the water pressure in the water supply pipe 11 is low pressure, a spring is installed on the upper part of the valve 12 or a magnet is attached to the lower surface of the valve 12 and the steel part is closed at the valve 12. By laying the ring, it is possible to obtain a full airtight effect by using the binding force between the magnet and the iron.

The present invention solves this problem and at the same time has the advantage of shortening the length of the support 16 by putting a heavy material such as water or sand in the float 17 while using the principle of the lever. have. In this case, the length of the support 16 is remarkably shortened, which can be hypothesized in a narrow space, and the manufacturing cost can be significantly reduced and the volume can be reduced, thereby reducing the logistics cost.

In addition, by laying the water level regulator 15, unlike the existing product also has the advantage that the user can accurately match the desired level.

The present invention as described above can reduce the manufacturing cost by manufacturing a synthetic resin than conventional brass products, has a pollution resistance and chemical resistance, low thermal conductivity is safe for freezing, and is advantageous for thermal insulation and cold storage.

In addition, when the product is fastened with a metal pipe, the existing product has a battery effect due to dissimilar metal, so it is difficult to dismantle later, but the present invention uses a synthetic resin, so it is easy to dismantle.

In addition, by installing a spring on the valve door to open the valve after a certain amount of water has drained, it prevents frequent opening and closing of the valve, and by filling the mouth with water or sand, the size of the mouth can be reduced. By attaching a function, the user can arbitrarily control the desired level.
