Description

Leakage check device for water supply equipment

According to the present invention, if a constant leakage occurs for a predetermined time in a water supply valve of a water supply tank, the water supply line of the water supply tank is automatically closed so that the water supply valve is shut off collectively, so that unnecessary leakage of the constant water generated through the water supply tank is prevented. The present invention relates to a water leakage preventing device for preventing water consumption and preventing energy from being consumed without using a constant water purification process in a multi-stage process, thereby resulting in an energy saving effect.

In general, a water supply fountain with a plurality of water supply valves is installed in a public facility including a school or a park, and a plurality of users can simultaneously drink water or wash their hands.

However, such a water supply fountain is a facility that is freely used by everyone regardless of gender, age, and age, so that users (especially children with insufficient attention) drink water or open the water supply valve to wash their hands, Or they often leave the fountain without locking. As a result, the constant water supplied to the consumer through several stages of water purification process is introduced into the sewer without being used, resulting in a waste of energy.

For this reason, an object sensing infrared sensor is provided on the water supply valve of the water supply tank, and a device is provided to open and close the water supply valve by a signal detected by the infrared sensor. In other words, when the user approaches the water inlet in the state where the user approaches the water fountain to wash his hand, the infrared sensor detects this and opens the water inlet valve, and closes the water inlet as the user finishes hand washing. The water supply valve was automatically shut off when the hand was removed.

However, since the device using the infrared sensor is installed on the water supply valve individually, a considerable cost is required for the facility, and the larger the water supply, the higher the installation cost. In addition, despite the need for such a large amount of facility costs, due to the characteristics of the infrared sensor vulnerable to external shocks and temperature changes, a problem occurs frequently, and since the water supply fountain is installed outdoors most of the time, this problem is further exacerbated. The result was a high cost and effort for maintenance and repair.

In addition, the infrared sensor detects the presence or absence of an object close to the water supply port of the water supply valve, and does not discriminate what the object is. Therefore, the water supply valve is opened by another organism such as a bird or a dog and water leaks. The problem was pointed out.

Accordingly, the present invention has been made in order to solve the above problems, the flow rate detecting means having a rotating body rotated by the fluid is installed on the water supply line of the drinking fountain, the flow rate through the rotation operation of such a rotating body When the detected signal value is kept constant for more than a certain time, the valve installed on the water supply line is configured to automatically shut off, thereby providing a water leakage prevention device for preventing leakage of water through the water supply fountain. The purpose is to.

It is configured to include the auxiliary line 100 to be.

2 and 3 are exploded perspective and combined cross-sectional view showing a detailed configuration of the flow rate detecting means 1, as shown in the flow rate detecting means 10 of the present invention, the housing 20 and the housing 20 The lower case 30, the upper case 40 and the cover 50 which are installed to be sequentially stacked inside the) and the impeller 60 installed in a rotatable state inside the lower case 30, and the impeller ( It is made of a rotary plate 70 installed inside the upper case 40 in a state that is fixedly coupled to the central axis (61) extending from the (60).

The housing 20 is a circular cylinder protruding the water inlet pipe 21 and the water outlet pipe 22 on both sides thereof, and the water supply line 1 of the water supply tank 1 is connected to the water inlet pipe 21 and the water outlet pipe 22. 2) is to be connected. The inner surface of the housing 20 is bent in multiple stages in the inner and outer directions, thereby forming a pair of upper and lower constant circulation paths 23 and 24 separated by the partition wall 25 in the housing 20. . The inlet pipe 21 and the outlet pipe 22 communicate with the pair of constant circulation paths 23 and 24, respectively.

The lower case 30 is coupled to the inside of the housing 20. The lower case 30 is a circular cylinder layered with respect to the center, and the bottom surface of the upper portion 31 having a large diameter is coupled in a state in which it is in close contact with the partition 25 formed inside the housing 20. will be. In addition, a plurality of drain holes 31a and a water supply hole 32a are respectively drilled in the circumferential surface of the upper portion 31 and the lower portion 32 formed at the bottom thereof, such a drain hole 31a and a water supply hole 32a. ) Is inclined in the opposite direction to each other, such that the drain hole (31a) and the water supply hole (32a) is in communication with the upper and lower side constant circulation paths (23, 24) formed inside the housing (20).

The upper case 40 is coupled to the upper end of the lower case 30 configured as described above. At this time, the bottom surface of the upper case 40 is provided with a recess 41 extending along the circumference thereof, the support jaw protruding in the upper portion 31 of the lower case 30 in such a recess 41 The 31b is fitted and coupled in close contact. In addition, by attaching a packing material to the contact portion between the lower case 30 and the upper case 40, it may be better to tightly close between the two members.

The cover 50 is coupled to the upper end of the upper case 40, the coupling of the cover 50 and the upper case 40 is the same as the coupling configuration between the upper and lower cases (30, 40). That is, the bottom surface of the cover 50 is provided with a recess 51 extending along its circumference, and the support jaw 42 protruding from the top of the upper case is fitted into the recess 51 to be in close contact. In addition, a protrusion 52 is formed on the upper side of the cover 50, and the protrusion 52 is supported over the engaging jaw portion 26 provided on the inner side of the upper portion of the housing 20. In addition, the coupling groove 53 is formed on the bottom surface of the cover 50 to install the hall sensor 54.

Then, the impeller 60 is installed in a rotatable state inside the lower case 30. The impeller 60 has a plurality of wings 62 extending radially with respect to the central axis 61 having a rotating ball 61a at the tip, and one side of the lower part of the central axis 61 is lowered. Rotating shaft 63 is coupled to the bottom of the case 30 is fitted. In addition, the central axis 61 of the impeller 60 is inserted into and supported by the support hole 43 perforated in the bottom of the upper case 40, the tip of which is coupled to the bottom of the cover 50 will be. In addition, a bushing 64 is provided between the inner surface of the central shaft 61 and the rotation shaft 63, and the bushing 64 is constantly rubbed with the rotation shaft 63 when the impeller 60 is rotated. Since the frictional force is small, it is desirable to produce a material that is not abrasion, in this embodiment, sapphire was used as this material.

The rotating plate 70 is fixedly coupled to the central axis 61 of the impeller 60 configured as described above. The rotating plate 70 is a recess 71 is formed in the center of the bottom surface, the central shaft 61 is fitted and fixed to the through-hole (71a) perforated in the recess 71. A pair of magnets 72 are attached to the outer end of the rotating plate 70, and the magnets 72 are installed to be in a straight line with respect to the center of the rotating plate 70.

By this configuration of the present invention, the constant introduced through the inlet pipe 21 of the housing 20 connected to the water supply line 2 while flowing along the lower constant circulation path 24 formed inside the housing 20 The lower case 30 is introduced into the lower case 30 through the water supply hole 32a drilled in the lower portion 32 of the lower case 30. In addition, the introduced constant is a constant circulation path above the housing 20 through the drain hole 31a of the upper portion 31 of the lower case 30 while rotating the impeller 60 installed inside the lower case 30. After being discharged to 23, it is introduced into the water supply line 2 through the water outlet pipe 22 of the housing 20. In this case, since the water supply hole 32a and the drain hole 31a are inclined in different directions, the rotational operation of the impeller 60 is performed as the constant flows inward and outward of the lower case 30. It is made more smoothly.

As the impeller 60 is rotated by such a series of operations, the rotating plate 70 fixed to the central axis 61 is also rotated at the same time. Accordingly, the pair of magnets 72 attached to the rotating plate 70 are rotated. As the Hall sensor 54 provided on the cover 50 is sensitive, the Hall sensor 54 detects a change in the magnetic field. Then, the flow rate of the constant passing through the water supply line (2) through the pulse generation cycle by the magnetic field change. That is, if the pulse generation period detected by the Hall sensor 54 is maintained at a constant state, it indicates that there is no change in flow rate, and if the generation cycle is severe, it indicates that there are many changes in the flow rate.

Then, the control unit 80 to receive the signal detected by the flow rate detecting means 10 having the above-described configuration is installed. The control unit 80 determines whether there is a constant leakage through the water supply basin 1 according to the input signal, and when the leakage of the constant is detected, outputs a control signal to the electric valve 90 to be described later to control the valve. To block.

The electric valve 90 is installed on the water supply line 2 adjacent to the water supply pipe of the water supply tank 1, and is opened and closed by a control operation of the controller 80. Accordingly, when the electric valve 90 is blocked, the constant supplied to the water supply line 2 is originally blocked from the initial inlet.

By such a configuration of the present invention, when the water flow rate sensing unit 10 detects a predetermined flow rate more than a predetermined time without being operated, the control unit 80 controls The water supply line 2 is shut off by judging it as an unnecessary leakage phenomenon, and when the flow rate detecting means 10 detects a change in the flow rate, the controller 80 allows the user to supply the water supply 1. It is determined that the use of the water supply line (2) while maintaining the open state is to continue the water supply through the drinking fountain (1).

In addition, a separate auxiliary line in the water supply line 2 located between the flow rate detecting means 10 and the electric valve 90 so that the electric valve 90 blocked in this way can be operated again in an open state. 100 is to be branched, such an auxiliary line 100 is connected to the baseboard water supply valve provided on one side of the water supply (1). That is, when the electric valve 90 is shut off and the damper water supply valve is opened to allow a constant flow to the auxiliary line 100, the flow rate detecting means 10 detects a constant flow rate. Accordingly, the controller 80 receiving the signal outputs a control signal to open the electric valve 90.

As such, the baseboard water supply valve is generally used for a long time for the purpose of cleaning or watering a flower bed, not for washing or drinking purposes. Therefore, another electric valve is provided and the effect of the electric valve is provided. It is rather inadequate to receive. In other words, if the baseboard water supply valve is also installed to be controlled by the electric valve, the hose is used at a relatively long distance in use and the valve is closed during spraying. Therefore, in order to restore it again, the user may have to run to the water fountain. In addition, the baseboard water supply valve is not a frequently used mechanism, and is also relatively easy to clean or lock after use. It is not economically suitable to apply an automatic control function for the purpose of the invention.

Referring to Figure 4 describes the operating state of the present invention configured as described above are as follows.

4 is a flow chart showing the operation of the present invention, as shown in the present invention, the valve opening confirmation step (S10), the flow rate detection step (S20), the valve cutoff determination step (S30), the control signal output step (S40) ), It is configured to include a valve blocking step (S50).

The valve opening checking step (S10) is a step of confirming whether the electric valve 90 installed on the water supply line 2 is opened or closed. When the electric valve 90 is opened, the water supply line of the water supply table 1 2) proceeds to the flow rate detection step (S20) to detect the flow rate of the constant flowing into.

The flow rate detecting step (S20) is a step of detecting the flow rate of the constant flowing into the water supply line (2) through the flow rate detection means 10 installed on the water supply line (2), installed inside the lower case (30) As the impeller 60 is rotated by the inflow of water, the rotating plate 70 fixed to the central axis 61 rotates at the same time, and covers the magnetic field generated by the magnet 72 provided in the rotating plate 70. As the Hall sensor 54 attached to the (50) is detected, the change in the flow rate through the pulse generation period according to the magnetic field detection.

Through such a flow rate detection step (S20) is to proceed to the valve blocking determination step (S30) to determine whether the shut off of the electric valve 90 according to the detected value.

That is, in the valve blocking determination step (S30), when the pulse generation period detected through the flow rate detecting means 10 is kept constant for a predetermined time or more, that is, if a change in the flow rate is not detected for a predetermined time or more, Through the water supply valve 3 of the water supply line (2) it is determined that the leakage of water is occurring.

When it is determined that there is a leakage of water in the valve blocking determination step (S30), the control signal output step (S40) for outputting a control signal to block the electric valve 90 is executed.

Then, when the control signal is output through the control signal output step (S40), it proceeds to the valve shut-off step (S50) to cut off the electric valve (90).

When the electric valve 90 is blocked through the valve blocking step (S50), since the constant flowing into the water supply line 2 of the drinking fountain 1 is originally blocked from the initial inlet, a further constant leakage phenomenon occurs. It doesn't work.

In addition, the electric valve 90 blocked through the above-described process is an electric valve unless a separate flow rate change is detected after the electric valve shut-off (S50) by the operation of opening the mop receiving water valve installed in the water supply (1). As described above, if the flow rate is detected by detecting the flow rate (S60), the flow rate detecting means 10 again controls the controller 80. By supplying a constant to the water supply line (2) by opening the electric valve (9) via.

As can be seen by the above embodiment, when the water leakage of the water supply station according to the present invention, water leakage of the constant water through the water supply valve of the water supply basin due to carelessness of the user, etc. In order to prevent the leakage of water, the constant is prevented.

In addition, the energy saving effect is obtained by preventing the waste of water as it is, even if the constant that has passed through various purification steps is not used.
