Description
Technical Field
The invention relates to a multi-project pipe network measuring instrument. In particular to a multi-project pipe network measuring instrument which can measure the characteristics of tap water at various places of a tap water pipe network to carry out maintenance and management and further carry out water quality management more accurately and safely.
Background
A pipe network measuring instrument according to the present invention is disclosed in korean registered patent publication No. 10-0945296 (hereinafter referred to as "prior art"). The prior art relates to a measuring device for constructing an optimal management system of a tap water pipe network, whereby tap water is a general term for facilities that purify water by using pipes and other buildings and supply it according to the needs of residents in cities, counties, and counties.
In general, tap water is obtained from a water source, introduced into a water purification plant, and then subjected to a process of improving water quality and distributed to various households and factories.
In this case, the process of supplying water to each consumer generally employs a method of supplying water from a water purification plant to a distribution basin in a region, and then supplying the water from the distribution basin to the consumers, or a method of supplying water from the distribution basin to each consumer via an intermediate storage tank.
The above-mentioned lines for supplying tap water are installed in a very wide area in a complicated manner, and these tap water supply lines are constructed in such a manner that a plurality of tap water networks having a certain length are connected. Namely, the tap water pipe network is connected in a net shape to form a tap water pipe network.
Therefore, in order to supply clean and sanitary tap water to consumers, it is necessary to manage not only water resources but also a tap water network. Particularly, since water purified to a clean state by a water purification plant is polluted by organic matters or heavy metals through an aged pipe network or leaks through a joint of a tap water pipe network, a comprehensive management and monitoring system for the above problems is required.
However, according to the prior art, the monitoring or measuring device for the current tap water pipe network is in a very laggard technical level, and generally only reaches a level of measuring the quality of tap water by installing a sensor in a distribution tank or an intermediate storage tank, but such a measuring method cannot measure the reduction of the quality of tap water generated in the process of supplying tap water from the distribution tank to each user, and therefore, there is a problem that an accurate measuring result cannot be obtained, and the requirement of safe water quality management cannot be met.
In addition, according to a general tap water pipe network measuring method of the related art, since only a part of the tap water pipe network is removed to know the water quality or to check the state of the pipe for the water quality of the pipe line supplied from the distribution tank to a consumer, there is a problem that the tap water pipe network is very difficult to measure, the operation cost and the measurement time are increased, and thus there is a problem that the substantial management is hardly performed.
In order to solve the above problems, the related art has been to install a measuring branch unit and a measuring sensor module in a tap water pipe forming a tap water pipe network, so that characteristics of tap water can be easily measured at various places of the tap water pipe network without disassembling the tap water pipe network for maintenance and management, thereby realizing more accurate and safe water quality management.
Here, in the measuring apparatus for constructing the optimal management system for the tap water network according to the related art, the measuring sensor module is inserted into the measuring branch pipe unit from the upper portion to the lower portion to measure the tap water characteristics, and after the measurement is finished, the measuring sensor module is separated from the measuring branch pipe unit and is released from the installation state.
However, the internal flow path of the water supply pipe generates water pressure at high pressures of, for example, 4 kilograms per square meter, which makes it difficult to insert the measurement sensor module. In addition, in the above process, there is a possibility that the measuring sensor module is ejected upward by water pressure, and thus there is a risk of a safety accident.
Therefore, in order to solve the above problems, the prior art has provided a sub-valve unit in the tap water pipe to block the flow of tap water. However, the above-mentioned interruption of the tap water causes another problem such as inconvenience to consumers who use the tap water.

Fig. 5 is a schematic view of the measurement sensor module 40 according to the embodiment of the present invention, as viewed from the bottom, showing the installation state of the measurement sensor 42 provided in the sensor main body 42 a.
As shown in fig. 1 to 5, the multi-project pipe network measuring instrument according to an embodiment of the present invention is used for easily measuring various characteristics of tap water including flow rate, water pressure, water quality (PH, residual chlorine, temperature, etc.), etc. in a tap water pipe 1 for supplying tap water, and includes a measuring sensor module 40 having at least two or more measuring sensors 42 for measuring various projects at one end thereof.
That is, the multi-project pipe network measuring instrument according to an embodiment of the present invention includes a Flange T-shaped pipe 10 in which a branch pipe 12 exposing an internal passage 1a of a tap water pipe 1 to the outside is formed in a direction crossing a longitudinal direction of the tap water pipe 1, a measuring sensor module 40 is installed in the tap water pipe 1 to measure characteristics of tap water, a valve unit 20 for opening and closing the branch pipe 12 at a branch pipe coupling Flange (Flange) of the Flange T-shaped pipe 10, and a main pipe 30 coupled to the valve unit 20 through a Flange.
The name sensor module 40 further includes a first Screw coupling portion 41 formed by a Thread (Thread) and a threaded rod (threaded rod) on an outer circumferential surface thereof, and a second Screw coupling portion 31 formed by a Thread and a threaded rod corresponding to the first Screw coupling portion 41 on an inner circumferential surface of the main pipe 30.
The branch pipe 12 is a hollow pipe having a diameter through which the measurement sensor module 40 can pass, and is formed, for example, in a vertical direction (90 °) intersecting with a longitudinal direction of the water supply pipe 1, and allows an acute angle and an obtuse angle to be horizontal. In addition, a flange is formed at the upper end to couple the valve unit 20 and the main pipe 30 by the flange.
The flanged T-pipe 10 including the branch pipe 12 is a medium for connecting the water pipe 1 and the measuring sensor module 40, and is formed by, for example, vertically dividing, and is attached to the water pipe 1 by a first auxiliary pipe 11 closely attached to the periphery of the water pipe 1, or is attached to the water pipe 1 in a longitudinal direction by a second auxiliary pipe 13 having flange fixing parts 13a formed at both ends.
The first auxiliary pipe member 11 includes a semicircular lower pipe member 11a, and an upper pipe member 11b assembled to the semicircular lower pipe member 11a by, for example, screwing (Bolting) or Welding (Welding) and integrally formed at an upper portion thereof and extending the branch pipe 12 upward.
Therefore, since the flanged T-pipe 10 can be attached to the water pipe 1 in a state where the tap water flows through the internal passage 1a of the water pipe 1, the tap water characteristics can be measured by a method without stopping the tap water, that is, a pressurized method.
In contrast, in a state where the tap water does not flow through the internal passage 1a of the water supply pipe 1, the tap water characteristics can be measured by attaching the flanged T-pipe 10 to the water supply pipe 1 through the second auxiliary pipe 13.
That is, the second auxiliary pipe member 13 is formed, for example, with the same diameter as the water supply line 1, and is extended upward by integrally forming a branch pipe at the upper portion thereof, and is formed with flange fixing portions 13a at both ends thereof, so that the flange T-pipe 10 can be attached to the water supply line 1 by the flange fixing portions 13 a.
In addition, according to the valve unit 20 of an embodiment of the present invention, the lower portion is flange-coupled to the branch pipe 12, and the upper portion is flange-coupled to the main pipe 30. The valve unit 20 opens the branch pipe 12 when, for example, Tapping with pressure (Hot Tapping) of a Tapping machine and inserting the measurement sensor module 40, and closes the branch pipe 12 when separating. Therefore, the valve unit 20 is provided with a handle 21 on the outside to be easily opened and closed.
That is, the valve unit 20 opens and closes the branch pipe 12, for example, by the operation handle 21 according to whether the tapping machine and the measuring sensor module 40 is inserted into the main pipe 30, specifically, when the tapping machine cutter and the measuring sensor module 40 are inserted to tap the tap water pipe 1 for tapping or tap water measurement, the branch pipe 12 is opened to pass therethrough, and when the tapping machine and the measuring sensor module 40 are separated after tapping and measurement, the branch pipe 12 is closed to prevent the tap water from flowing out.
Here, the valve unit 20 is configured as a single-structure one-stage structure or as a double-structure two-stage structure including the auxiliary valve unit 50, for example. In addition, a gasket 60 may be provided between the main pipe 30 to seal the middle thereof.
Therefore, according to an embodiment of the present invention, maintenance for repair or replacement can be easily performed through the valve unit 20 having the dual structure, the life thereof can be effectively extended, and a water leakage phenomenon of tap water, which can occur during the measurement of tap water, can be effectively prevented by the gasket 60.
The flange is coupled to the upper portion of the valve unit 20 by a flange coupling part 32, for example, to facilitate installation of a general driver 43b including a Motor (Motor) so as to guide the measurement sensor module 40 to the branch pipe 12, the flange being coupled to the main pipe 30 of the valve unit 20 by a flange.
That is, the driver 43b is flange-coupled by the flange installation part 32, so that the connection and linkage between the driver 43b and the measurement sensor module 40 can be easily realized.
In addition, according to the measuring sensor module 40 of an embodiment of the present invention, at least two or more measuring sensors 42 for measuring characteristics of the tap water flowing along the tap water pipe 1 are installed at the lower end. Further, the first screw coupling portion 41 is formed by processing the outer peripheral surface to form a screw and a threaded rod.
That is, the measurement sensor module 40 may include a sensor body 42a having at least two or more measurement sensors 42 mounted on a lower end thereof, a body 40a having the sensor body 42a on a lower end thereof and having a first screw coupling portion 41 formed on an outer circumferential surface thereof, a polygonal connector 43 formed on an upper end of the body 40a, and handles 43a installed on both sides of the connector 43.
Therefore, the measuring sensor module 40 is rotated manually by the handle 43a, or the measuring sensor 42 is installed in the internal passage 1a of the water pipe 1 while being rotated automatically by linking the driver 43a to the upper end of the measuring sensor module 40.
Here, the sensor body 42a is detachable from the body 40a, and the measurement sensor 42 provided in the sensor body 42a may be detachable. For example, the measurement sensor 42 may include a flow sensor that can measure the flow rate of tap water, a water quality sensor that can measure the water quality (PH, residual chlorine, temperature, etc.) of tap water, and a camera module (Cameramodule) may be added.
In addition, a Stopper Pin (Stopper Pin) may be formed to protrude downward at a lower end of the sensor body 42a so that a depth may be limited during the installation of the measurement sensor 42 in the inner passage 1a of the water pipe 1, thereby preventing the above-mentioned measurement sensor 42 from colliding with the ground of the water pipe 1.
That is, after the measurement sensor module 40 is installed on the water supply pipe 1, it is difficult to recognize the installation state of the measurement sensor 42 from the outside, and thus, the depth thereof is limited by the stopper pin to protect the measurement sensor 42.
In addition, the first screw coupling portion 41 according to an embodiment of the present invention may be implemented, for example, by a method of forming a thread and a threaded rod by machining an outer circumferential surface of the body 40a using a CNC lathe or the like. In addition, the second screw coupling portion 31 may be implemented by forming a screw thread and a threaded rod corresponding to the first screw coupling portion 41 on the inner circumferential surface of the main pipe 30.
For example, the first and second screw coupling portions 41 and 31 have substantially the same Pitch (Pitch) formed so that the measuring sensor 42 can be easily inserted into the internal passage 1a of the water pipe 1 while rotating after the measuring sensor 40 is screwed into the main pipe 30.
Here, the main body 40a formed with the first screw coupling portion 41 and the main pipe 30 formed with the second screw coupling portion 31 may be formed of a metal material such as Stainless Steel (Stainless Steel), which prevents the screw threads of the first and second screw coupling portions 41 and 31 from being worn out during the process of repeatedly screw-coupling the first and second screw coupling portions 41 and 31.
That is, the main body 40a and the main pipe 30 made of stainless steel have higher durability and are not rusted than other metals, so that the first and second screw coupling portions 41 and 31 can be prevented from being worn.
Therefore, according to an embodiment of the present invention, it is possible to prevent the measurement sensor module 40 from being separated from the main pipe 30 and being blown out due to the water pressure during installation or separation of the measurement sensor module 40 due to interference between the threads of the first and second screw coupling parts 41 and 31, thereby preventing safety accidents from occurring.
The following is a detailed description of the method for measuring the tap water characteristics in the pressurized mode using the various-project pipe network measuring instrument of the present invention:
first, in the method for measuring characteristics of tap water using the multi-item network measuring instrument according to the embodiment of the present invention, the tap water pipe 1 is perforated by a pressurized perforation without stopping the tap water, and the opening 1b exposed to the outside through the branch pipe 12 is formed.
For example, in order to measure the characteristics of tap water under pressure without cutting off the water and opening the hole, it is necessary to Bypass a device for measuring the characteristics of tap water and install a branch line (Bypass) through which tap water can flow in the tap water pipe 1, which increases not only the scale of equipment but also the time and cost of construction.
On the contrary, according to an embodiment of the present invention, the method for measuring tap water characteristics by tapping the tap water pipe 1 with pressure is constituted only by installing a device for measuring tap water characteristics, thereby not only reducing the scale but also reducing the time and cost.
The Tapping under pressure of the tap water guanao 1 can be performed by a Tapping Machine (Tapping Machine) which can be attached to and detached from the main pipe 30 through a flange. That is, the flange T-pipe 10 is closely fitted around the water pipe 1 through the first auxiliary pipe 11, and the valve unit 20 is opened after the valve unit 20 is coupled to the branch pipe 12 of the flange T-pipe 10 through the flange.
After the valve unit 30 is flanged to the tapping machine, the Cutter (Cutter) of the tapping machine is moved forward by the branch pipe 12 opened by the valve unit 20, and the tap water pipe 1 is driven to open the upper portion thereof, thereby forming the opening 1 b.
When the opening 1b is formed in the tap water pipe 1, the cutter is retracted, and then the branch pipe 12 is closed by the valve unit 20, thereby separating the tapping machine from the valve unit 30. After the tapping machine is separated, the valve unit 20 is flange-coupled to the main pipe 30, and the measuring sensor module 40 is screwed to the main pipe 30 to prepare for measuring the tap water characteristics.
Here, the measurement sensor 42 installed in the measurement sensor module 40 is inserted into the internal channel 1a of the water pipe 1 by screwing the first screw coupling part 41 formed on the outer circumferential surface of the measurement sensor module 40 to the second screw coupling part 31 formed on the inner circumferential surface of the main pipe 30 and then rotating it manually by the handle 43a or automatically by the actuator 43 b.
Therefore, according to an embodiment of the present invention, since various items of characteristics of tap water including flow rate, water pressure, and water quality (PH, residual chlorine, temperature, etc.) can be easily measured by a pressurized method without stopping the tap water, inconvenience caused by measuring the characteristics of the tap water by a pressurized method without stopping the tap water or tapping the tap water under pressure can be effectively eliminated.
