Description

Turbidimeter system for valve room, smart valve room equipped with the same, and control method of the smart valve room {Turbidimeter system for valve room, smart valve room equipped with it, and control method of the smart valve room}

The present invention relates to a turbidity meter system for a valve room, a smart valve room equipped with the same, and a control method for the smart valve room. More specifically, the present invention relates to a turbidity meter system for a valve room, a smart valve room equipped with the same, and a control method for the smart valve room. More specifically, the turbidity of tap water is measured in the valve room through which tap water produced at a water purification plant passes through to determine whether it is unsuitable for drinking. In the case of turbidity, the turbid contaminated water does not pass through the internal piping in the valve room and is purified through a filter before being supplied to the intended use. However, when a turbidity meter is installed in the bypass pipe installed in the internal piping and the turbidity is measured, the turbidity is measured inside the turbidity meter. With the flow of tap water stopped, turbidity can be measured after a certain period of time has elapsed, the water has become calm and the bubbles have disappeared, and the turbidity meter system included in the present invention includes a cleaning means to accurately measure turbidity in the valve room. This is to make it possible and thereby provide hygienic tap water to tap water users.

In general, tap water is made by sending water from rivers and lakes to a water purification plant and going through various purification processes to create drinking water. This water is then supplied to users such as homes, buildings, and industrial facilities through water pipes. do.

A plurality of room-shaped valve rooms are installed at random distances in the middle of the water pipe pipe, and valves and flow meters are installed in the internal pipes that pass through the inside of the valve room to prevent accidents such as damage to the water pipe buried in the ground. In cases where a leak occurs or when carrying out work such as replacing an old pipe, close the valve in the valve room adjacent to the water pipe being replaced or repaired to prevent tap water leakage, and use a pressure gauge or flow meter installed in the valve room. The flow of tap water is monitored and managed.

However, if an abnormality such as a breakdown occurs in the treatment facility of a water purification plant, or the water pipes that supply tap water to users deteriorate, problems may arise where contaminated water is supplied to users such as general homes.

Examples of contaminated water being incorrectly supplied to users include incidents in Incheon and Bucheon where red tap water (red water, green water) and tap water containing larvae were supplied, and citizens' anxiety is rising due to a series of incidents related to drinking water. Users who have taken this problem into account are using water purifiers, but when a rust incident occurs, the filter of the water purifier quickly becomes clogged, making it difficult to use the water purifier. Contaminated water containing rust coming from faucets other than the water purifier is There was a problem that users could not solve.

As mentioned above, since tap water users cannot choose the quality of tap water to be supplied, this is a technology that allows users to use tap water with peace of mind by managing the quality of the tap water right before it is supplied to users such as homes, buildings, and industrial facilities. We were faced with a situation where we had to develop .

As related prior art, the invention of Patent Publication No. 10-2017-0076389 (Prior Art Invention 1) is known through the Publication of Patent Publication, but it is a separate invention with many differences from the present invention in its composition and resulting effects. .

Another prior invention is registered as Patent Registration No. 10-0643176 (Previous Invention 2) and is known through the patent publication.

The "Previous Invention 2" is capable of measuring turbidity under certain conditions by supplying the sample water to be measured at a constant flow rate and flow rate, confirming the flow or state of the sample water, and removing air bubbles from the blister removal unit to remove air from the sample water. It is stated in the patent specification of "Conventional Invention 2" that it enables accurate turbidity measurement and cleans the measuring device through high-pressure spraying. When foreign substances are deposited on the lens surface of the sensor part in the cleaning part, it is rotated by a motor. It is also described as a cleaning brush used to clean the surface of the lens.

Since this "Prior Art Invention 2" is installed in a raw water plant such as a water purification plant to measure turbidity of the water in the water purification plant, as described above, when an abnormality occurs in the treatment facility of the water purification plant, or between the water purification plant and the user, In the case where contaminated water is generated due to the aging of the connecting water pipe, there is a problem that contaminated water comes out at the point of use even when “Conventional Invention 2” is installed.

In addition, "Previous Invention 2" is said to measure turbidity under certain conditions by supplying sample water to be measured at a constant flow rate and flow rate, and to clean the measuring device through high-pressure spraying. In this way, the sample water moves or is sprayed at high pressure. When the water sloshes around, bubbles are generated, and when the light from the luminescent sensor shines on the sample water, the above bubbles are mistaken for foreign substances, and the light is reflected and scattered by the bubbles, making accurate turbidity measurement difficult. .

Also, when foreign substances are deposited on the lens surface of the sensor unit, the surface of the lens is cleaned with a cleaning brush rotated by a motor. This means that the position where the cleaning brush stops after cleaning the lens surface covers the light emitting sensor or light receiving sensor. In the case of stopping in position, there was a problem in that the light from the luminescent sensor could not shine on the sample water, making it impossible to measure the turbidity of the sample water.

The present invention is intended to solve the above problems. The present invention measures the turbidity of tap water in the valve chamber through which tap water produced at a water purification plant passes, and if it is unsuitably turbid for drinking water, the turbidity is prevented from passing through the valve chamber. It is purified through a filter and supplied to the point of use. However, when a turbidity meter is installed in the bypass pipe installed in the internal piping inside the valve room and the turbidity is measured inside the valve room, the tap water is stopped inside the turbidity meter so that the water is calm and does not shake. It is possible to measure turbidity after a certain period of time has elapsed in a decomposed state and the bubbles have disappeared, and the turbidity meter system included in the present invention includes a cleaning means to enable accurate turbidity measurement in the valve room, thereby providing hygienic conditions for tap water users. The technical task is to provide tap water.

In order to achieve the above object, the turbidity meter system for the valve room according to the present invention has a manhole device and a pipe inlet and pipe installed on the upper and both sides of the valve room body, and a valve is provided inside the valve room body between the pipes on both sides. In a known valve room where internal piping is installed;

In the internal pipe in front of the valve, a turbidity meter unit is installed to measure the turbidity of tap water flowing through the internal pipe. This turbidity meter unit consists of a bypass pipe whose both ends are connected to the internal pipe, a turbidity meter installed in the middle of the bypass pipe, and a turbidity meter. It is installed on the branch pipe and water return pipe connected to the front and rear, respectively, and includes valves that individually open and close the branch pipe and water return pipe included in the bypass pipe;

The turbidimeter is characterized in that it includes a control unit that calculates and displays measurement data of foreign substances contained in tap water measured.

In addition, a number of smart valve chambers equipped with a turbidity meter system for the valve chamber according to the present invention are installed on the inner surface of the valve chamber body and the outer peripheral surface of the internal piping including the turbidity meter system for the valve chamber, so that the valve chamber body and the valve chamber body may be damaged by natural disasters or external forces. A plurality of sensors capable of detecting and measuring sensing data transmitted to internal piping;

It is installed inside the valve room body, and collects, stores, and manages the sensed data detected through multiple sensors and turbidity meters, controls each valve, pressure gauge, and air exhauster, and transmits the sensed data to a control center on the ground. It includes a control unit that receives signals input from the control center;

The sensor is used as one or a combination of two or more of a vibration detection sensor, a noise detection sensor, a strain gauge, a flow meter, and a pressure gauge, and the sensed data detected or measured by the sensor is used for natural disasters such as earthquakes and sinkholes, or pipes and pipes. It is characterized by including a configuration that allows it to be used for leak detection and damage diagnosis of internal piping.

And, the control method of the smart valve room according to the present invention is a control method of the smart valve room using a smart valve room equipped with a turbidity meter system for the valve room;

A water normal supply step in which each valve installed in the large-diameter internal pipe and the small-diameter bypass pipe is completely opened to allow a small amount of water to bypass the bypass pipe, and the bypassed water joins the internal pipe and flows to the point of use;

A water confinement step of locking the front valve after closing the rear valve to trap water inside the bypass pipe and the turbidity meter and stop the flow of water;

an air discharge step of opening the air discharger installed in the turbidity meter for a certain period of time to exhaust the air inside the turbidity meter so that bubbles disappear;

A turbidity measurement step of measuring the turbidity of the water contained inside the turbidity meter using a turbidity sensor installed in the turbidity meter;

If the turbidity measured in the turbidity measurement step is normal, a secondary water supply step of completely opening the internal pipe and bypass pipe to allow the water to flow to the user, as in the normal water supply step;

If the turbidity measured in the turbidity measurement step is abnormal, close the valve and open the front valve installed in the bypass pipe installed in the internal piping to bypass the valve, so that the water in front of the valve bypasses the bypass pipe and is purified in the filter. It is characterized by including a water emergency supply stage in which the water is treated and supplied to the point of use, and the abnormal turbidity is transmitted to the control center so that action can be taken.

As discussed above, the present invention installs a bypass pipe in the internal pipe installed inside the valve room, installs a turbidity meter in the middle of the bypass pipe, installs valves in the bypass pipes on the front and rear sides of the turbidity meter, and provides air to the turbidity meter. By installing an exhaust device, when the valves on the front and rear sides of the turbidity meter are closed and a predetermined time has elapsed, the water trapped in the turbidity meter becomes calm and air containing bubbles is discharged, which has the effect of accurately measuring the turbidity of tap water in the valve chamber.

In addition, during the process of measuring the turbidity of tap water in the turbidity meter, tap water continues to flow through the internal pipe, which has the effect of enabling turbidity measurement of tap water without turning off the water. The turbidity meter is equipped with a cleaning means to clean the inside of the turbidity meter. This has the effect of accurately measuring the turbidity of the water inside the turbidity meter.

Also, if a measurement result that is unsuitable for drinking water occurs during the process of measuring turbidity for tap water inside the valve chamber as above, the valve is closed to block the contaminated water from being supplied to places such as homes, and then a separate drain pass is used. Contaminated water flows through the pipe, but a filter is installed in the bypass pipe so that the contaminated water is supplied to the user in a state where it has been purified by the filter. Even if contaminated water is generated due to equipment failure at the water purification plant or old pipes, the contaminated water is supplied to the user. It has the very useful effect of purifying and supplying it to the point of use.

In addition, a separate turbidity meter unit is additionally installed in the bypass pipe behind the filter, so that when the filter is clogged with contaminants, a signal is sent through the control unit indicating the degree of clogging, so the filter is replaced at an appropriate time and clean tap water is always supplied to the user. There is an effect that can be obtained, and there is a very useful effect of being able to measure salinity while maintaining the water stationary inside the turbidity meter at a constant temperature by additionally installing a chlorine sensor, temperature sensor, and heater in the turbidity meter.

In addition, the present invention traps water in a turbidity meter, cleans the inside of the turbidity meter, measures the turbidity of tap water, purifies and supplies even when contaminated water occurs, and displays the replacement time of the filter. This is done automatically by the control unit, and the signal is shared with the control center for all of the above, which has a very special effect in that clean tap water can always be supplied to users.

In addition, the present invention has a very practical effect in that it can cope with not only water quality measurement as described above, but also natural disasters such as earthquakes and sinkholes, and accidents such as leak detection and damage diagnosis of pipes and internal pipes.

Hereinafter, the turbidimeter system for the valve room according to the present invention, the smart valve room equipped with the same, and the control method of the smart valve room will be described with reference to the attached drawings FIGS. 1 to 12.

First, in explaining the present invention, the symbol “100” is used to refer to the valve chamber, and it should be noted that this valve chamber 100 is the same as the smart valve chamber.

The turbidity meter system 200 for a valve room according to the present invention is installed in the internal pipe 150 installed inside a known valve room 100, as shown in Figures 1 to 3, and measures the water flowing through the internal pipe 150. It measures turbidity.

The known valve room 100 has an internal piping 150 installed inside the valve room body 110, which has a manhole device 120 on the upper side and piping inlet pipes 130 on both sides, and this internal piping 150 ), a valve 151 is installed to open and close the internal piping, and a pressure gauge and flow meter are additionally installed depending on the purpose. On the outside of this internal piping 150, tap water is supplied from a water purification plant to users such as general homes or industrial facilities. The supply water pipe (same as the plumbing pipe 140) is connected.

The turbidity meter system 200 has a turbidity meter unit 201 installed in the internal pipe 150 in front of the valve 151, and this turbidity meter unit 201 has a bypass pipe 152 in which the turbidity meter 210 is installed in the middle. is connected and installed, and valves 155 and 156 are installed to be able to open and close, respectively, in the branch pipe 153 and the water return pipe 154 connected to the front and rear of the turbidity meter 210.

If all valves 155 and 156 are closed with water flowing into the bypass pipe 152, the water is trapped in the bypass pipe 152 and water no longer flows into the bypass pipe 152. , When a predetermined period of time elapses in this state, the water inside the bypass pipe 152 including the turbidity meter 210 becomes calm rather than turbulent, and the turbidity including the light-emitting member 221 and the light-receiving member 222, which will be described later, increases. The turbidity of the water contained inside the turbidity meter 210 is measured using a sensor.

The internal pipe 150 shown in FIGS. 1 and 2 is shown to be formed of one pipe body, and the internal pipe 150 shown in FIG. 3 is constructed by connecting at least two T-type connectors. The internal pipe 150 can be formed from a single pipe body or by connecting two or more tee-type connectors.

However, in the case of forming the internal pipe 150 with one pipe body, it is cumbersome to drill a hole in the internal pipe 150 and then connect the ends of the branch pipe 153 and the water return pipe 154 to the drilled hole. It is inconvenient, and there is the inconvenience of having to perform additional anti-corrosion treatment on the perforated part of the metal pipe. However, when using two or more Tee-type connectors, the branch pipe (153) and the water return pipe are installed in the vertical part of the Tee-type connector. Since the ends of (154) are directly connected, there is the convenience of working without the need for drilling and anti-corrosion treatment.

As shown in FIGS. 1 to 3 and 5 and 6, the turbidity meter 210 is formed with an inlet 211 connected to the branch pipe 153 and a drain 212 connected to the water return pipe 154, respectively, and a lower A casing 215 in which light transmission holes 213 and 214 are formed on both sides to face each other is provided, and a casing cover 216 is installed on the upper part of this casing 215 to be open and closed.

As the casing cover 216 is opened and closed on the upper part of the casing 215, the transparent container 220 can be freely inserted and removed from the inside of the casing 215, and the inside of the casing 215 including the transparent container 220 By cleaning it cleanly, it is possible to accurately measure the turbidity of the water inside the transparent container 220 using a turbidity sensor including the light-emitting member 221 and the light-receiving member 222.

In addition, the inlet 211 is connected in the tangential direction of the cylindrical casing 215, so that water flowing in through the inlet 211 rotates in a spiral along the inner wall of the casing 215, causing foreign substances to form on the inner wall of the casing 215. This prevents them from sticking, and in the process, the inner wall surface of the casing 215 and the inner wall sides of the transparent container 220 are cleaned.

An air discharger 217 is installed on the upper side of the casing cover 216 to discharge the air inside the casing 215 to the outside. For example, this air discharger 217 is installed with a solenoid valve to connect the bypass pipe 152. When the water is trapped in the bypass pipe 152 and the turbidimeter 210 by closing each valve (155, 156) installed in the turbidimeter, air containing bubbles is released from the water contained in the bypass pipe 152, including the turbidimeter 210. This prevents air bubbles from being measured as foreign substances during the water turbidity measurement process.

In addition, inside the casing 215, a transparent container 220 whose body faces the light transmitting holes 213 and 214 on both sides is installed to be insertable and removable, and the entire upper circumference of the transparent container 220 is sealed by a watertight means. 215) is installed to be watertight with the inner surface.

At this time, the watertight means is to install packing (p), for example, on the entire upper circumference of the transparent container (220) to prevent water on the upper side of the transparent container (220) from seeping into the light transmission holes (213, 214) from the inside of the casing (215). will be.

In addition, a turbidity sensor using a known transmission and scattered light measurement method is installed outside the casing 215 outside the light transmission holes 213 and 214 on both sides, which includes a light emitting member 221 that irradiates laser light and a transparent container 220. ) Light receiving members 222 that transmit light scattered through the water contained in the light receiving members 222 are installed to face each other.

In addition, a control unit 230 is installed at a predetermined position on one side of the valve chamber body 110 to calculate and display measurement data of foreign substances contained in tap water using light received from the light receiving member 222.

A pressure gauge 157 is installed in the internal pipe 150 or the branch pipe 153, or the internal pipe 150 and the branch pipe 153, and the internal pipe 150 and the branch pipe measured by the pressure gauge 157 ( 153), the opening and closing amount of the valve 151 is electronically controlled by the control signal from the control unit 230 according to the water pressure within the valve, and each of the valves 155 and 156 and the air exhauster 217 are also controlled according to the control signal from the control unit 230. It is installed and controlled electronically.

The water flowing into the inlet 211 spirals down inside the casing 215 and cleans the inner wall of the casing 215 and the transparent container 220, and then passes through the drain hole 212 to the water return pipe 154. ) is continuously carried out along with water flowing into the internal pipe 150, thereby minimizing scale accumulation inside the casing 215 and the transparent container 220.

As the saying goes, “a rolling stone does not gather moss,” when the flow of water stops in a pipe, foreign substances such as mold or scale are easily generated by the moisture on the inner surface, so it is necessary to use the bypass pipe (152). This is to ensure that water flows continuously.

In Figure 5, the drain 212 is formed in the lower center of the casing 215, and the drain portion 220a is formed in the lower center of the transparent container 220 at a corresponding position. However, the drain 212 ) may be formed on the side wall of the casing 215 on the upper side of the transparent container 220, as in "C", and may be formed in a cup shape without forming a drain portion 220a on the transparent container 220.

The following is a description of this embodiment of the turbidity meter 210 shown in FIGS. 7 to 9. This embodiment of the turbidity meter 210 includes an inlet 211 in the configuration of one embodiment of the turbidity meter 210 shown in FIG. 5. A technology has been added to clean the inside of the casing 215 by rotating the water wheel 240 and the cleaning blade 245 by the water flowing out from ).

Accordingly, the description of the same configuration will be omitted and only the additional configuration of this embodiment of the turbidity meter 210 will be described in detail.

That is, this embodiment of the turbidity meter 210 includes a water turbine 240 that rotates by the water jetting out from the inlet 211 inside the casing 215, and is installed on the lower side on the same axis as the water turbine 240. Cleaning blades 245 are installed to clean the inner surface of the transparent container 220 by rotating with it and rubbing against the inner surface of the transparent container 220. The rotary blade 241 of the water wheel 240 is installed at the inlet 211. An oblique bend 242 inclined in the opposite direction is formed, so that the water wheel descends and rotates in the process of the water current hitting the oblique bend 242 at an angle.

In addition, a shaft support ring 246 is installed inside the casing 215 between the water wheel 240 and the cleaning blade 245 to support the rotating shaft 244 that axially couples the water wheel 240 and the cleaning blade 245. In addition, a spring 247 whose elasticity is weaker than the water pressure of the water jetting out from the inlet 211 is elastically installed between the central boss portion of the shaft support ring 246 and the boss portion 243 of the water wheel 240.

Therefore, in this embodiment of the turbidity meter 210, when the water flow ejected from the inlet 211 hits the inclined bend 242, the water turbine 240 descends due to the water pressure hitting the inclined bend 242. As it rotates and the water wheel 240 descends, it is fixed to the boss part 243 of the water wheel 240 and the boss part of the lower cleaning blade 245 to the rotation shaft 244, so that the water wheel 240 lowers. The rotating shaft 244 and the cleaning blade 245 descend together, and the spring 247 is compressed.

At this time, since the water pressure erupting from the inlet 211 is stronger than the elasticity of the spring 247, the water wheel 240 and the cleaning blades 245 rotate as they descend, and the water wheel 240 and the cleaning blades 245 rotate in this way. ) is in contact with the inner wall of the casing 215 and the transparent container 220, respectively, so that foreign substances, including scale, do not stick to the inner wall of the casing 215 and the transparent container 220 and are cleaned.

As shown above, the outer ends of the water wheel 240 and the cleaning blade 245 are cleaned while contacting the inner wall of the casing 215 and the transparent container 220, respectively, so the contact portion is made of a soft material such as soft synthetic resin or silicone. It is desirable to do so.

In order to perform the water confinement step (S3) of trapping water inside the bypass pipe 152, which will be explained later, when the valves 155 and 156 installed in the bypass pipe 152 are closed, water flows into the bypass pipe 152. Since water does not flow into the water wheel 240, the rotation shaft 244 and the cleaning blade 245 including the water wheel 240 rise due to the elasticity of the spring 247, as shown in (b) of Figure 7. Likewise, the laser light (L) emitted from the light emitting member 221 is transmitted through the water contained in the transparent container 220 without being blocked by the cleaning wing 245, and the light is received by the light receiving member 222, so that the light contained in the transparent container is The turbidity of water is measured.

The following is a description of three embodiments of the turbidity meter 210 shown in FIG. 10, in which a hollow pipe shaft 248 is installed in the upper and lower center directions of the casing 215, and turbidity sensors are installed at the top and bottom of the hollow pipe shaft 248. The light emitting member 221 and the light receiving member 222 are installed facing each other.

That is, in the three embodiments of the turbidity meter 210, the light transmission holes 213 and 214 are formed at the upper and lower sides of the upper and lower centers of the casing 215, and the upper light transmission holes 213 are formed on the casing cover 216. It is formed to extend inward from the inner bottom surface to rotate and support the upper part of the hollow tube shaft 248, and the inlet 211 and drain 212 are formed in the casing 215 in a horizontal direction.

In addition, a shaft support ring 246 is installed inside the casing 215 below the inlet 211 and the drain 212 to rotate and support the middle portion of the hollow pipe shaft 248, and the light transmission holes 213 and 214 are provided. A hollow tube shaft 248 having several holes 249 formed on the entire surface is rotatably inserted into the central hole of the upper light transmission hole 213 and the shaft support ring 246.

In addition, outside the hollow tube shaft 248 on the upper and lower sides of the shaft support ring 246, there is a water wheel 240 that rotates due to the water flowing out from the inlet 211, and a transparent container 220 that rotates with the water wheel 240. A cleaning wing 245 is installed to clean the inner surface of the light-transmitting hole 213, and a light-emitting member 221 is installed on the upper part of the casing cover 216 above the light-transmitting hole 213, and the casing 215 below the light-transmitting hole 214. A light receiving member 222 is installed in the lower part of .

In the turbidity meter 210 shown in FIG. 10, the water wheel 240 rotates due to the water flowing in the horizontal direction, and the hollow tube shaft 248 and the cleaning blade 245 rotate together due to the rotation of the water wheel, thereby rotating the casing 215. ) and the inside of the transparent container 220 is cleaned, and the water flowing into the casing 215 flows into the inside of the hollow pipe shaft 248 through the plurality of holes 249.

Accordingly, turbidity is measured for the water flowing into the hollow pipe shaft 248 by the light emitting member 221 and the light receiving member 222 installed opposite to each other above and below the hollow pipe shaft 248, as indicated by the arrow. “L” indicates a state in which the laser light emitted from the light emitting member 221 is illuminated on the light receiving member 222.

The following is a description of an actual example of the turbidity meter 210 shown in FIG. 11, which includes a chlorine sensor 250, a temperature sensor 251, and a heater 252 in the turbidity meter 210 of an embodiment shown in FIG. 5. ) is additionally installed, and the chlorine sensor 250, temperature sensor 251, and heater 252 are also connected and controlled to transmit and receive with the control unit 230.

At this time, the chlorine sensor 250 and the temperature sensor 251 are installed in the casing 215 or the casing cover 216, and the tip detection portions of each sensor 250 and 251 are installed to contact the water contained in the casing 215. , It is desirable to install the heater on the outer peripheral surface of the casing 215.

The turbidity meter 210 in the actual example measures the temperature of the water trapped inside the turbidity meter using the temperature sensor 251 in a calm state where the water is trapped inside the turbidity meter and does not move, just as when measuring turbidity in the turbidity meter. , the chlorine concentration is measured using the chlorine sensor 250 while maintaining the temperature of the water inside the turbidimeter constant by controlling the heater 252 to the temperature (about 25°C) set in the control unit 230 according to the temperature. will be.

The chlorine sensor is a known device that measures the concentration of chlorine based on electrical conductivity. The electrical conductivity is affected by the temperature of the fluid and its value increases as the water temperature increases. Therefore, it is desirable to always measure electrical conductivity at a constant temperature.

The present invention measures the turbidity and chlorine concentration of water flowing through pipes buried in the ground, and the temperature of water flowing through pipes buried in the ground differs greatly between winter and summer. According to this situation, in the present invention, the temperature of the water trapped inside the turbidity meter is detected using the temperature sensor 251, the temperature of the heater 252 is adjusted according to the detected temperature, and the chlorine concentration is adjusted when the set temperature is reached. This is to ensure that accurate measurements are possible regardless of the season.

The size of the turbidity meter applied to the present invention is small enough to hold a small amount of water, about 0.3 to 0.5 liters, so it does not take much time to maintain a small amount of water at a temperature of about 25°C, and the power consumption is low. It is revealed that this exists.

The following is a description of the valve chamber 100 provided in the turbidimeter system 200 shown in FIGS. 2 and 3.

One embodiment of the valve chamber 100 shown in FIG. 1 includes the turbidity meter system 200, and a plurality of sensors 231 are installed on the inner surface of the valve chamber body 110 and the outer peripheral surface of the internal pipe 150. Installed, it can detect and measure water quality, including sensing data transmitted to the valve chamber body 110 and the internal pipe 150 due to natural disasters or external forces, and water pressure and turbidity of water flowing inside the internal pipe 150.

In addition, it is installed inside the valve chamber body 110, and collects, stores, and manages the sensed data detected through a plurality of sensors 231 and the turbidity meter 210, and stores each valve (151, 155, 156) and the pressure gauge (157). , Controls the air exhauster 217, and includes a control unit 230 that transmits the sensed data to a control center on the ground and receives signals input from the control center.

In addition, the sensor 231 is used as one or a combination of two or more of a vibration detection sensor, a noise detection sensor, a strain gauge, a flow meter, a pressure gauge, and a water quality detection sensor, so that the sensed data sensed or measured by the sensor 231 It includes a configuration that can be used for natural disasters such as earthquakes and sinkholes, leak detection and damage diagnosis of the pipe 140 and internal pipe 150, and water quality measurement.

The following is a description of this embodiment of the valve chamber 100 shown in FIG. 4, in which the turbidity of water is measured above the set value in the turbidity meter 210 included in the embodiment shown in FIG. 1, and the water is used as drinking water. If it is not suitable, close the valve 151 installed in the internal pipe 150 to block the turbid contaminated water from being supplied to the place of use, and then use a bypass pipe 160 that bypasses the internal pipe 150 in front and behind the valve 151. ) is installed, and a filter 161 is installed in the bypass pipe 160 to supply the filtered water to the user.

Therefore, in describing this embodiment of the valve chamber 100, description of the same configuration as the embodiment shown in FIG. 1 will be omitted and only the added configuration will be described in detail.

In this embodiment of the valve chamber 100 shown in FIG. 4, a bypass pipe 160 with a filter 161 installed in the middle is connected to the internal pipe 150 at the front and rear of the valve 151, and a filter ( 161) A front valve 162 is installed in the bypass pipe 160 on the front side, and a rear check valve 163 is installed in the bypass pipe 160 on the rear side of the filter 161, and the filter 161 and A turbidity meter unit 201 is additionally installed in the bypass pipe 160 between the rear check valves 163 to measure the turbidity of water flowing through the bypass pipe 160 behind the filter 161.

It should be noted that the turbidimeter unit 201 installed in the bypass pipe 160 is configured in the same way as the turbidimeter unit 201 installed in the wooho pipe 152, and that the water filtered while using the bypass pipe 160 is The replacement time of the filter 161 can be confirmed by measuring the turbidity.

Next, the control method of the smart valve room will be described with reference to FIG. 12.

1 to 4 and 12, the valve 151 installed in the large-diameter internal pipe 150 and the valves 155 and 156 installed in the small-diameter bypass pipe 152 are fully opened to open the pipe 140. At the same time as water flows into the internal pipe 150 including Execute the normal supply stage (S1) of water that merges and flows to the point of use.

At this time, the pipe 140 receives raw water (tap water) from a water purification plant and supplies it to the user, so the internal diameter of the internal pipe 150 including the pipe 140 is larger than the water pipe installed in places of use such as factories, including general homes. It is large, and since the inner diameter of the pipe 140 is installed in various sizes depending on the place of use, the most commonly used pipe of 80 to 100 mm is set as the dimensions of the internal pipe 150 and the pipe 140 to implement the present invention. Explain.

When the pipe 140 and the internal pipe 150 are used with an internal diameter of 80 to 100 mm, the bypass pipe 152 installed in the internal pipe 150 of 80 to 100 mm is used in general homes and buildings. Connect and install a small-diameter pipe with an inner diameter (20 mm) similar to the water pipe mainly used in.

The reason why the bypass pipe 152 is formed with a small diameter of about 20 mm is that when measuring turbidity of water in the turbidity measurement step (S5) performed later, the bypass pipe 152 and the turbidity meter 210 are used. If the size is large and contains a large amount of water, the water sloshing width is large and it takes a lot of time for the bubbles to disappear, so the bypass pipe 152 is formed with a small diameter of about 20 mm, and the bypass pipe 152 It should be noted that the size of the turbidity meter 210 installed in ) is designed to be small, with an inner diameter of about 50 to 100 mm.

The water normal supply stage (S1) is a stage in which water from the purification plant is normally supplied to users through the pipes 140 and internal pipes 150 passing through a plurality of valve chambers 100, and the internal pipes 150 are Since the diameter is large and the bypass pipe 152 is a small diameter, the water pressure of the water passing through the internal pipe 150 is higher than the water pressure of the water bypassing the bypass pipe 152.

In this way, as water continues to flow through the internal pipe 150 and the bypass pipe 152 in the process of supplying water to the user, scale or foreign matter may form on the inner peripheral surface of the internal pipe 150 and the bypass pipe 152. This minimizes sticking or stagnation, and as shown in Figures 5 and 6, the inlet 211 through which water flows into the casing 215 included in the turbidity meter 210 flows in the tangential direction of the cylindrical casing 215. Thus, the incoming water current continuously contacts the inner surface of the casing 215, thereby minimizing the adhesion or stagnation of water stains and foreign substances.

As described above, when supplying water to a user and measuring the turbidity of water passing through the pipe 140 and the internal pipe 150 according to need and purpose, the bypass pipe 152 is connected by a control signal from the control unit 230. An internal cleaning step (S2) is performed to clean the internal flow path of the bypass pipe 152 including the turbidity meter 210 by allowing water to flow rapidly.

In the internal cleaning step (S2), as shown in Figures 1 to 3, the inside of the internal pipe 150 and the bypass pipe 152 is measured by the pressure gauge 157 installed in the internal pipe 150 and the bypass pipe 152. Detects the pressure of flowing water. By partially closing the valve 151 installed in the internal pipe 150 according to the pressure set by the control signal from the control unit 230 so that the water pressure of the water flowing through the bypass pipe 152 increases according to the detected water pressure signal, the internal pipe 150 is partially closed. As the amount of water flowing through the pipe 150 decreases, the water pressure of the internal pipe 150 decreases, and conversely, the water pressure of the water flowing through the bypass pipe 152 increases.

Partially closing the valve (151) from above causes the valve to be 20 to 25% open rather than completely closed, thereby reducing the amount of water (flow rate) passing through the internal pipe (150) to which the valve is connected by 20 to 25%. As the flow rate decreases, the flow rate decreases, while the flow rate of water passing through the bypass pipe 152 increases as the internal pipe decreases by 20 to 25%, thereby increasing the flow rate.

The 20-25% reduction described above is because the inner diameter of the large-diameter internal pipe (150) is 80-100 mm, and the inner diameter of the small-diameter bypass pipe (152) is about 20 mm, which explains the ratio of the diameter sizes of the large diameter and small diameter. There is no need to accurately determine the flow rate in the bypass pipe 152. If the flow rate is 2 to 3 times faster than the flow rate of water flowing through the bypass pipe 152 in the normal water supply stage (S1), the turbidity meter 210 will increase as the flow rate becomes faster. As the friction speed with the internal surface increases, there is a cleaning effect, and accidents such as damage to the bypass pipe 152 and the turbidity meter 210 due to the 2 to 3 times faster flow rate do not occur.

As the water pressure of the water flowing through the bypass pipe 152 increases, the flow rate of water flowing inside the bypass pipe 152 and the turbidity meter 210 increases, and as shown in FIG. 6, the water flows in a tangential direction to the casing 215. As this erupts, the faster water current contacts the inner peripheral surface of the casing 215 in a spiral shape and cleans the inner peripheral surface of the turbidity meter 210 in the process of escaping through the drain hole 212 on the lower side of the turbidity meter 210.

In this way, after the cleaning operation has been performed for the time (about 30 seconds) set in the control unit 230 in the internal cleaning step (S2), the water confinement step (S3) is performed to trap water inside the turbidity meter 210.

At this time, the valve 151 installed in the internal pipe 150 is fully opened to allow water to flow normally into the internal pipe 150 as in the water normal supply stage (S1), and the water return pipe is operated by a signal set from the control unit 230. Close the rear valve (156) installed at (154).

After closing the rear valve 156 in this way, when the front valve 155 installed on the branch pipe 153 is closed 1 to 2 seconds later, the bypass pipe 152 between the front and rear valves 155 and 156 and the turbidity meter are connected. As water is trapped in (210), no more water enters or leaves the bypass pipe (152).

In this way, water is trapped in the bypass pipe 152 and the turbidity meter 210 between the front and rear valves 155 and 156, and since water no longer flows in, the water trapped in the bypass pipe 152 and the turbidity meter 210 does not slosh around. It gradually decreases and becomes calm.

In this state, the air discharger 217 installed on the upper side of the casing 215 is opened after a predetermined time (5 to 10 seconds) has passed since the front and rear valves 155 and 156 are closed according to a signal from the control unit 230. An air discharge step (S4) is performed in which the air inside the casing 215 and the air including air bubbles in the water trapped in the turbidity meter 210 are discharged to the outside through the air discharger 217.

The opening time of the air discharger 217 is set to 30 to 60 seconds, and the air discharger 217 is closed after the air including air bubbles is discharged for the set time. In this way, 3, air discharge steps (S3, S4) While executing, the water trapped inside the turbidity meter 210 is calm and bubbles are removed.

After executing the air discharge step 54 as above, a turbidity measurement step S5 is performed to measure the turbidity of the water filled in the transparent container 220 inside the turbidity meter 210.

The measurement method for measuring the turbidity of water is the same as the known turbidity measurement, by irradiating laser light from the light emitting member 221 installed on the lower side of the turbidity meter 210 toward the light receiving member 222, and the laser light is transmitted into a transparent container ( The light scattered while passing through the water contained in 220 is received by the light receiving member 222, and the received signal is processed in the control unit 230 to measure the turbidity of the water.

The results of measuring the turbidity of the water are input to the control unit 230, and the measurement results are transmitted to the control center for control and management. If the turbidity measurement results in the turbidity measurement step (S5) are suitable for drinking water, the results are input to the control unit 230. In the second water supply step (S6), each valve (155, 156) installed in the bypass pipe (152) is opened to ensure that water is normally supplied to the previously opened internal pipe (150) and bypass pipe (152). do.

As described above, the normal supply of water to the internal pipe 150 and the bypass pipe 152 means that part of the water flowing through the internal pipe 150 flows into the branch pipe 153 of the bypass pipe 152 and is measured by the turbidity meter 210. This refers to a situation in which water joins the internal pipe 150 through the water return pipe 154 and flows to the external pipe 140 through the rear of the internal pipe.

Even at this time, opening each valve (155, 156) installed in the bypass pipe 152 causes water to continuously flow into the bypass pipe 152, as described above, and the inside of the bypass pipe 152 including the turbidity meter 210. This is to minimize the occurrence of foreign substances or scale.

The present invention traps water in the bypass pipe as water continues to flow through the internal pipe 150, exhausts air containing bubbles, and measures turbidity for water even in the 3~ turbidity measurement steps (S3 ~ S5). It is characterized by the normal supply of water to the user during the process.

If the result of measuring the turbidity of the water is unsuitable for drinking water, as shown in FIG. 4, close the valve 151 installed in the internal pipe 150 to block the contaminated water from being supplied to the user, and then close the valve 151. ), but the contaminated water flows through the bypass pipe (160), and a filter (161) is installed on the bypass pipe (160) so that the contaminants in the contaminated water are purified in the filter (161) and can be consumed. Execute the water emergency supply step (S7) to ensure that water is supplied to the user.

A front valve 162 is installed in the bypass pipe 160 on the front side of the filter 161, and when the front valve 162 is opened, water flowing into the internal pipe 150 on the front side of the valve 151 flows. It flows into the bypass pipe 160, and the contaminated water flowing into the bypass pipe 160 is purified while passing through the filter 161, and the closed valve ( 151) It joins the rear internal pipe 150 and flows to the place of use.

A rear check valve 163 is installed in the bypass pipe 160 behind the filter 161, so that water behind the rear check valve 163 does not flow back toward the filter 161.

As described above, even in a situation where contaminated water is generated and the contaminated water is measured, the contaminated water is purified and sent to the place of use, and the signal is input to the control unit 230, and the input signal is transmitted to the control center to take appropriate action. to take.

In the process of executing the above water emergency supply step (S7), the water is purified in the filter 161 and flows to the internal pipe 150 behind the valve 151 through the bypass pipe 160 behind the filter 161. The secondary turbidity measurement step (S8), which measures the turbidity of water, is additionally performed.

In the process of executing the water emergency supply step (S7), if filtration and purification of foreign substances in the contaminated water continues for a long time in the filter 161, the contaminants contained in the contaminated water accumulate in the filter 161 and filter. Since (161) is clogged, the turbidity of the water purified and discharged from the filter (161) is measured using the turbidity meter unit (201) installed in the bypass pipe (160) behind the filter (161).

The process of measuring turbidity in the turbidity meter unit 201 installed in the bypass pipe 160 above is the same as measuring turbidity in the turbidity measurement step (S5).

Even in the process of measuring turbidity in the turbidity secondary measurement step (S8), purified water is supplied to the user through the bypass pipe 160, and is measured by the turbidity meter unit 201 installed in the bypass pipe 160. The turbidity is input to the control unit 230 to indicate the replacement time of the filter 161.

The unexplained reference numeral “215a” in the drawing refers to a lower cover that covers the outside of the light emitting member 221 and the light receiving member 222.
