Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-item pipe network measuring apparatus and a multi-

The present invention relates to a multi-item network analyzer. More particularly, the present invention relates to a multi-item pipe network measuring apparatus for measuring and maintaining the characteristics of tap water at various points of the tap water network, and thereby managing water quality more accurately and safely.

The network analyzer according to the present invention is disclosed in Patent Document 1. (Patent Document 1) relates to a measuring apparatus for constructing an optimal management system for a water supply pipe network. According to the present invention, a water supply facility is a facility for supplying water in accordance with the demand of residents of cities, towns and villages by purifying water by pipes and other workpieces .

The construction of the waterworks is usually done by taking water from a water source, passing it to a water purification plant, and then distributing it to each home and factory through a process of improving water quality.

At this time, the process of supplying water to each consumer is generally composed of a method of supplying water from a water purification plant to a reservoir in each region and then supplying water to a consumer from a reservoir or a method of supplying water to each consumer through a reservoir have.

The lines for supplying the waterworks are installed in a very large area in a complicated manner. Such water supply lines are constructed by connecting a plurality of water supply pipe networks having a certain length. In other words, the water supply network is connected to the network to form a single water supply network.

Therefore, in order to supply clean and hygienic water supply to consumers, it is very important to manage the water supply network as well as water resources management. In particular, clean water purified through a water purification plant is polluted with organic matter or heavy metals through aged pipe network, or water is leaked through joints of the water supply pipe network. Therefore, a comprehensive management and monitoring system for this Is required.

However, according to (Patent Document 1), the current monitoring or measurement value of the water supply network remains at a very low level, and generally, the sensor is installed in a reservoir or an intermediate storage tank to measure the water quality of the water. However, The system can not measure the water quality deterioration that may occur during delivery to each user from the reservoir, so that accurate measurement results can not be obtained, thereby failing to meet safe water quality management.

In addition, the conventional water pipe network measuring method according to the related art is performed in such a manner as to disassemble a part of the water pipe network to check the water quality or to check the piping condition in order to inspect the water quality of the pipe line supplied from the reservoir to the customer, There is a problem that the measurement work of the pipe network is very difficult, and the work cost and the measurement time are increased. For this reason, the practical management is hardly achieved.

In order to solve such a problem (Patent Document 1), the measurement branching unit and the measurement sensor module are installed in the water supply pipe forming the water supply pipe network, and the characteristics of the water supply is easily measured at various points of the water supply pipe network without disassembling the water supply pipe Thereby enabling more accurate and safe water quality management.

In the measurement apparatus for constructing the optimal water management network management system according to Patent Document 1, the measurement sensor module is inserted into the measurement distribution unit from the upper side to the lower side to mount the measurement sensor module in the lower direction, and water quality characteristics are measured. The mounting state is dismantled by separating the measurement sensor module from the branch unit.

However, water pressure is generated at a high pressure of about 4 kg / m < 2 > for example in the internal flow path of the water supply piping, which causes considerable difficulty in inserting the measurement sensor module. In this process, the measurement sensor module may be ejected upward by the water pressure, which may cause a safety accident.

Therefore, in order to solve such a problem (Patent Document 1), a sub-valve unit is installed in the water pipe to block the flow of the water. However, there is another problem such that the number of such waterworks can cause inconvenience of the consumer who uses the waterworks.

4 is a perspective view of a flange T-type pipe 10 installed on a water pipe 1 through a semi-circular lower fitting 11a and an upper fitting 11b according to an embodiment of the present invention. The valve unit 20 is flanged to the branch pipe 12 and the main fitting 30 is flanged to the valve unit 20 and the measurement sensor module 40 is attached to the main fitting 30 And screwed through the threaded fastening portions 41 and 31. As shown in Fig.

FIG. 5 is a view showing the measurement sensor module 40 according to an embodiment of the present invention when viewed from the bottom. FIG. 5 shows the arrangement state of the measurement sensor 42 provided in the sensor body 42a.

1 to 5, the multi-item pipe network measuring apparatus according to the embodiment of the present invention can measure the flow rate, the flow rate, the water pressure and the water quality (PH, residual chlorine, temperature, etc.) in the water supply pipe 1 supplying the water supply And includes a measurement sensor module 40 having at least two measurement sensors 42 provided at one end for easily measuring different characteristics of the waterworks including the multi-item measurement.

That is, the multi-item pipe network measuring instrument according to an embodiment of the present invention includes a measurement sensor module 40 mounted on a water pipe 1 so as to measure the characteristics of the water pipe, the internal channel 1a of the water pipe 1 A flange T-shaped pipe 10 having a branch pipe 12 exposed externally in a direction intersecting with the longitudinal direction of the water pipe 1, a flange 10 fastened to the branch pipe 12 of the flange T pipe 10, (20) for opening / closing the valve unit (12), and a main fitting (30) flange fastened to the valve unit (20).

The first screw connection part 41 formed by forming a screw thread and a thread rod on the outer circumferential surface of the measurement sensor module 40 and the screw thread connection part 41 corresponding to the first screw connection part 41, And a second screw coupling portion 31 formed by forming a rib on the inner circumferential surface of the main fitting 30.

The branch pipe 12 is a hollow pipe having a diameter permitting the measurement sensor module 40 to pass therethrough. For example, the branch pipe 12 is formed in a vertical direction (90 °) which is an intersecting direction with respect to the longitudinal direction of the water pipe 1, And obtuse angles are acceptable. And a flange is formed at the upper end so that the valve unit 20 and the main fitting 30 are flanged.

The flange T-shaped pipe 10 including the branch pipe 12 is a kind of medium that connects the water pipe 1 and the measurement sensor module 40 and is formed by being divided into, for example, upper and lower parts and closely attached to the periphery of the water pipe 1 Can be installed in the water supply pipe 1 through the first auxiliary fitting 11 installed or longitudinally installed in the water supply pipe 1 through the second auxiliary fitting 13 having flanged portions 13a formed at both ends thereof have.

The first auxiliary fitting 11 is assembled to the semicircular lower fitting 11a and the lower fitting 11a by bolting or welding and the upper tubular body 12 is integrally formed And an extended upper fitting 11b.

Therefore, since the flanged T-shaped pipe 10 can be installed in the water pipe 1 in a state in which the tap water flows into the internal passage 1a of the water pipe 1, the water pipe can be installed in the water pipe 1, Can be measured.

The flange T-shaped pipe 10 is installed on the water pipe 1 through the second auxiliary fitting 13 to measure the water quality characteristic in a state in which no water flows into the internal passage 1a of the water pipe 1 .

That is, the second auxiliary fitting 13 is formed to have the same diameter as that of the water supply pipe 1, for example, the upper branch tube 12 integrally extends upward, and the flange portion 13a is formed at both ends, The flange T-shaped pipe 10 can be installed in the water supply pipe 1 through the fixing portion 13a.

Meanwhile, the valve unit 20 according to an embodiment of the present invention is flanged to the lower branch tube 12 and the main fitting 30 is flanged to the upper portion. For example, the valve unit 20 opens the branch pipe 12 when the hot-tapping and the measurement sensor module 40 are inserted, and the branch pipe 12 is closed when the valve unit 20 is detached . Therefore, the valve unit 20 can be provided with a handle 21 on the outside so that the valve unit 20 can be easily opened and closed.

That is, the valve unit 20 opens and closes the branch tube 12 by operating the handle 21, for example, depending on whether the perforator and the measurement sensor module 40 are inserted into the main fitting 30. More specifically, When the cutter and measurement sensor module 40 of the perforator are inserted to puncture the drill hole 1 or to measure the water quality characteristics, the branch tube 12 is opened so that the cutter and the measurement sensor module 40 can pass therethrough, When the sensor module 40 is detached, the branch tube 12 is closed so that the tap water does not leak out.

Here, the valve unit 20 may be composed of, for example, a single stage of a single structure or two stages of a dual structure including an auxiliary valve unit 50. And between the main fitting 30 and the gasket 60, the water-tightness between them can be achieved.

Therefore, according to the embodiment of the present invention, maintenance and repair for repairs, replacement, and the like can be easily performed through the valve unit 20 having a double structure, so that the service life thereof can be effectively extended. It is possible to effectively prevent leakage of the water from the water.

The main fitting 30 flanged to the valve unit 20 is flanged on the valve unit 20 to guide the measurement sensor module 40 to the branch pipe 12 and includes a motor And a flange mounting portion 32 formed at an upper portion thereof to facilitate installation of a normal actuator 43b.

That is, the actuator 43b is fastened in a flanged manner through the flange mounting portion 32, so that connection and interlocking between the actuator 43b and the measurement sensor module 40 can be facilitated.

Meanwhile, the measurement sensor module 40 according to an embodiment of the present invention is provided with at least two measurement sensors 42 for measuring the characteristics of the water flowing along the water pipe 1 at the bottom. Then, the outer peripheral surface is processed to form the threads and the valleys, thereby constituting the first screw coupling portion 41.

That is, the measurement sensor module 40 includes a sensor body 42a having at least two measurement sensors 42 disposed at the lower end thereof, a sensor body 42a at the lower end thereof, and a first screw connection portion 41 A polygonal connector 43 formed on the upper end of the main body 40a and a handle 43a mounted on both sides of the connector 43. The main body 40a includes a main body 40a,

The measuring sensor module 40 may be manually rotated using the handle 43a or the actuator 43b may be connected to the upper end of the measuring sensor module 40 to be interlocked, Is disposed in the internal passage (1a) of the water supply pipe (1).

Here, the sensor body 42a can be detachably attached to the main body 40a, and the measurement sensor 42 provided on the sensor body 42a can also be detachably attached thereto. For example, the measurement sensor 42 may include a flow sensor capable of measuring the flow rate of the water supply and a water quality sensor capable of measuring the water quality (PH, residual chlorine, temperature, etc.) of the water supply. Can be added.

The stopper pin is protruded downward from the lower end of the sensor body 42a so that the depth of the sensor 42 can be limited in the process of disposing the measurement sensor 42 in the internal passage 1a of the water pipe 1 Therefore, it is possible to prevent the measurement sensor 42 from colliding with the bottom surface of the water pipe 1.

That is, after the measurement sensor module 40 is mounted on the water pipe 1, it is difficult to identify the placement state of the measurement sensor 42 from the outside. Therefore, Thereby limiting the depth.

Meanwhile, the first screw fastening part 41 according to an embodiment of the present invention can be formed by forming a thread and a bone by machining the outer circumferential surface of the main body 40a through a CNC lathe or the like. The second threaded fastening portion 31 is formed by forming a thread and a corresponding thread on the inner circumferential surface of the main fitting 30 with the first threaded fastening portion 41.

For example, the first and second screw fastening portions 41 and 31 are formed to have substantially the same pitch so that the measurement sensor module 40 is screwed to the main fitting 30, Can easily enter the internal passage 1a of the water supply pipe 1. [

Here, the main fitting 30, in which the main body 40a and the second screw coupling part 31 are formed, may be formed of a metal material such as stainless steel. This is to prevent the threads of the first and second screw fastening portions 41 and 31 from being worn out during the repeated screw fastening of the first and second screw portions 41 and 31.

That is, the main body 40a and the main fitting 30 made of a stainless steel material are more durable than other metals and do not rust, so that wear of the first and second screw fastening portions 41 and 31 can be prevented.

Therefore, according to the embodiment of the present invention, due to the interference between the threads through the first and second screw fastening portions 41 and 31, the measurement sensor module 40 40 can be prevented from being separated and ejected from the main fitting 30, thereby preventing the occurrence of safety accidents.

Hereinafter, a method of measuring the water quality of the endless water system using the multi-item pipe network measuring instrument of the present invention will be described in detail as follows.

First, a method of measuring the characteristics of a tap water using a multi-item pipe network measuring instrument according to an embodiment of the present invention includes drilling a tap water pipe 1 through a continuous tap water hole without splitting the tap water, The opening 1b to be exposed must be formed.

For example, in order to measure the characteristics of tap water by the end water system without end water piercing, it is necessary to install a kind of bypass line in the water pipe (1) so that tap water can flow by bypassing the devices necessary for tap water characteristic measurement Thereby increasing the size of the facility and increasing the construction period and cost.

On the other hand, as in the embodiment of the present invention, the method of measuring the tap water characteristic by drilling the tap water pipe 1 through the end water piercing is performed only by installing the devices necessary for measuring the tap water characteristics, It is possible to shorten the period and reduce the cost.

A tapping machine may be used to drill the bottom end water of the water pipe 1 so as to be detachably attached to the main fitting 30 in a flange fastening manner. The flange T-type pipe 10 is closely attached to the periphery of the water pipe 1 through the first auxiliary fitting 11 and the valve unit 20 is connected to the branch pipe 12 of the flange T- And then the valve unit 20 is opened.

Thereafter, the cutter of the perforator is advanced through the branch pipe 12 which is opened through the valve unit 20 after the perforator is flanged to the valve unit 30, and then the cutter is driven to move the upper part of the water pipe 1 Thereby forming the opening portion 1b.

When the opening 1b is formed through the opening of the water pipe 1, the cutter is moved backward and then the branch tube 12 is closed by the valve unit 20 and the perforator is separated into the valve unit 30. When the separation of the perforator is completed, the main fitting 30 is flanged to the valve unit 20, and the measurement sensor module 40 is screwed to the main fitting 30 to measure the water quality characteristic. I am ready.

The measurement sensor module 40 has a first screw fastening portion 41 formed on the outer circumferential surface thereof is screwed to a second screw fastening portion 31 formed on the inner circumferential surface of the main fitting 30, The measuring sensor 42 mounted on the measuring sensor module 40 enters the internal passage 1a of the water pipe 1 through the automatic rotation using the actuator 43a or the actuator 43b.

Therefore, according to the embodiment of the present invention, it is possible to easily measure the multi-items of the water quality including the flow rate, the flow rate, the water pressure and the water quality (PH, residual chlorine, temperature, etc.) , It is possible to effectively solve the inconvenience of measuring the tap water characteristics in a single end water system or other end water system other than the end water piercing.
