Abstract

The present invention relates to a supply control device for a small-scale water supply system with an improved water leakage prevention function and, more specifically, to a novel concept of preventing water leakage during the supply of valley water while two ball valves installed to operate individually in a valley water pipe and an overflow pipe is opened and closed in opposite directions. The conventional supply control device for a small-scale water supply system is configured that a valve float stand instantaneously repeats the rotation operation. Therefore, as the time passes, a valve shaft is warped. The water level of a water tank cannot be precisely adjusted as the gap of a ball valve increases and leakage occurs. The wear of a part (ball, sheet, etc.) is severe and durability is lowered. To solve these problems, two water supply ball valve and overflow ball valve are installed on a water supply pipe and an overflow pipe branching to both sides at the upper end of a valley water pipe, respectively. The two water supply ball valve and overflow ball valve are opened and closed in opposite directions by the rotation operation of a supply float and an overflow float which are interlocking with each other according to change of water level so as to precisely control the flow paths of the water supply pipe and the overflow pipe simultaneously.

Description

Technical Field [0001] The present invention relates to a simple water supply control device with improved water leakage prevention function,

The present invention relates to a novel concept of preventing water leakage during the supply of valleys while two ball valves installed to operate individually in valley water pipes and overflow pipes mutually open and close.

Generally, in the island area where the water supply is not popular, or in the mountain area of Dumese, the self-service waterworks are operated by the villages or the local areas. Most of these waterworks are installed with water tanks as high as the middle of the mountain, And the motor pump is operated to raise the ground water to store the water in the water tank or the natural valley water flowing along the valley without using the motor pump is stored in the water tank and supplied to the water tank have.

However, since most of the waterworks facilities are located in mountainous areas, they are not easy to access, and since the field managers are selected as villagers who are non-experts, it was very difficult to manage them.

In particular, in order to use the simple tap water as drinking water, the disinfectant must be injected into the water supplied to the water tank to eradicate various germs. However, since the administrator can not visit the dispenser directly and periodically, Disinfecting medicines are automatically put in.

In the case of the simplified water supply system to which the disinfectant dispenser is applied, the disinfection water has to be consumed until the concentration of the disinfected water is lowered due to the lowering of the concentration of the disinfectant solution over time (2 to 3 days) Without consuming it, new water and disinfectants will be supplied immediately, so that the villagers will consume the dilution of the existing disinfected water and the newly disinfected water.

Therefore, the existing disinfected water is completely stored in the water tank for a long time and the concentration of the disinfectant completely disappears, causing the villagers to drink water that has not been properly disinfected.

As a method for solving such a problem, Patent Registration No. 1306919 entitled " Name / automatic control device for supplying water to a valley for a simple water supply "

The valve unit of the prior art maintains the fixed state even when the water level rises or falls. When the water level reaches the maximum water level or the minimum water level, the water circulation operation is instantaneously performed. Thus, until the water in the water tank is consumed, And the operation of accurately restarting the supply of the water of the valley is automatically controlled by consuming a certain amount of the disinfected water in the water tank.

 However, in the prior art, the valve unit is configured to repeatedly perform the swing operation momentarily without rotating slowly with a change in the water level. As a result, the impact applied to the valve shaft accumulates as time passes and the valve shaft is twisted, The water level of the water tank can not be precisely adjusted, and wear of the parts (ball, sheet, etc.) is so severe that the durability is lowered.

In addition, in the prior art, when the groundwater is used due to a shortage of valleys, it is troublesome to install a water pipe connecting the groundwater pipe to the water supply pipe. In order to selectively mix the water of the valleys and groundwater, And the water pipe (valley water pipe) are mutually reversed.

In order to solve the above-mentioned problems, the present invention provides a water supply system comprising two water supply ball valves and an overflow ball valve, each of which is provided separately on a water supply pipe and an overflow pipe, The flow of the water supply pipe and the overflow pipe can be precisely controlled at the same time while opening and closing the water supply port and the overflow port.

In addition, according to the present invention, when a valley water flows in through a water pipe connected to one side of a mixed water collecting tank, a valley receiving water discharge plate is opened so that the number of valleys can be discharged through a mixed water outlet through the inside of the mixed water collecting tank, When the groundwater is introduced through the groundwater pipe connected to the other side, the groundwater drainage plate is opened and the groundwater can be discharged through the mixed water tank through the mixed water outlet.

According to the present invention, since the two water supply ball valves and the overflow ball valves open and close each other in opposite directions, the overflow pipe is closed at the same time that the water supply pipe is opened and the overflow pipe is opened simultaneously with closing of the water supply pipe, And the number of valleys at the full water level of the water tank is automatically drained to the outside through the overflow pipe.

In addition, the water supply port and the overflow port of the present invention can be smoothly pivoted in response to the water level change, thereby eliminating the impact applied to the valve shaft, preventing the valve shaft from slipping, It supplies hygienic water that maintains the concentration suitable for drinking by adjusting the water level of the tank precisely, and it suppresses occurrence of wear of various parts (ball, sheet, etc.), and dramatically improves the durability.

Further, according to the present invention, when the valley water flows in, the valley receiving water discharge plate is opened so that the number of the valleys can be discharged through the mixed water discharge port through the mixed water collecting tank and the underground water receiving plate is opened when the ground water flows, The mixed water can be selectively mixed with the valley water.

In addition, when the groundwater is used due to the lack of the valley number, it is possible to eliminate the inconvenience of additionally installing a water pipe connecting the groundwater pipe to the water pipe, and in order to selectively use the valley water and ground water, Thereby providing an effect of eliminating the inconvenience of use that must be opened and closed.

Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

The present invention is characterized in that a valley water pipe (10) is connected to the interior of a water tank (1) so that natural valley water can be stored inside the water tank (1) The number of the valleys introduced into the valley water pipe 10 is supplied to the water tank 1 through the water supply pipe 20 or the flow rate of the overflow pipe 30 is reduced by installing the water pipe 20 and the overflow pipe 30 on both sides of the overflow pipe 30 to be drained to the outside.

In the present invention, when the ball valve is gradually opened and closed by controlling the flow rate of the flow path to the water supply pipe (20) and the overflow pipe (30) simultaneously by using one ball valve, considering that leakage occurs, The two ball valves divided into the water supply ball valve 40 and the overflow ball valve 50 are organically connected so as to solve the conventional problem that the ball valve 50 is not moved even when the ball valve 50 moves, .

To this end, a water supply ball valve 40 is installed in the water supply pipe 20, and an overflow ball valve 50 is separately installed in the overflow pipe 30.

A valve stem 61 is integrally fitted to the valve stem 41 of the water supply and supply ball valve 40 and a water level change (rise and fall) of the water tank 1 is provided at the lower end of the valve stem 61. [ The water supply ball valve 40 can control solely the opening and closing of the water supply pipe 20 by forming the water supply port 60 which gradually turns upward and downward in accordance with the flow rate of the water.

A valve seat 71 is integrally fitted to the valve shaft 51 of the overflow ball valve 50 and a change in the water level of the water tank 1 The overflow ball valve 50 can control solely the opening and closing of the overflow pipe 30 by forming the overflow port 70 for gradually turning up and down in accordance with the flow rate of the overflow.

Therefore, when the water feed ball valve 40 and the overflow ball valve 50 are low in level, the water feed port 60 and the overflow port 70 are rotated upward The flow path of the overflow pipe 30 is closed at the same time that the flow path of the water supply pipe 20 is opened and the flow of the water is smoothly supplied to the inside of the water tank 1 through the water supply pipe 20, The flow path of the overflow pipe 30 is opened at the same time as the flow path of the water supply pipe 20 is closed, and the number of the valleys that are unnecessarily introduced is drained to the outside through the overflow pipe 30.

When the water supply ball valve 40 and the overflow ball valve 50 reach the full water level, the water supply port 60 and the overflow port 70 are rotated upward The flow path of the overflow pipe 30 is opened and the water supply is stopped until a predetermined amount of the disinfected water in the water tank 1 is consumed (a time point when the water level reaches the minimum water level) Thereby providing a more effective supply of hygienic water to the villagers that maintains a concentration suitable for drinking.

The present invention provides an excellent effect of preventing the water from leaking through the overflow pipe (30) when the overflow pipe (30) is immediately closed when the water supply is started, and at the same time, the water supply port (60) 70 gradually slows down the valve shafts 41, 51 to prevent the valve shafts 41, 51 from being displaced, as well as preventing the ball valve from increasing in clearance, And provides a special effect of blocking the generation of wear and abrasion of various parts.

The water supplied to the water supply pipe 20 can be directly supplied to the interior of the water tank 1 and connected to the disinfectant dispenser 2 installed in the water tank 1, Most of the supplied water is supplied to the water tank 1 as well as a part of the water is distributed and supplied to the aberration of the disinfectant dispenser 2 so that the auricle can be rotated without power to use as a power source for pumping and dispensing the disinfectant.

Meanwhile, the water pipe 20 of the present invention is further combined with a valley water source capable of selectively mixing valleys or ground water according to the circumstances, and a technology for connecting the device to the underground water mixing device 100, It is possible to easily supply the gas to the fuel cell 1.

As shown in FIGS. 5 to 8, the mixed-valley water and underground water mixing apparatus 100 includes an organic combined structure of the mixed water collecting tank 110, the valley receiving water receiving plate 120, and the ground receiving water receiving plate 120a.
