Description

SMART WATER VALVE MEASURING WATER PRESSURE AND TRANSMITTING WIRELESS DATA}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smart water dispenser valve capable of hydraulic pressure measurement and wireless output, and more particularly, from a tap water control valve (gate valve or butterfly valve) installed in an underground valve chamber or valve box. It is related to a smart distillation valve that can measure the water pressure automatically at the request of the administrator and transmit it wirelessly, so that the water supply manager can check the text or voice at the terminal and wirelessly output the water.

Although a water separator valve (gate valve or butterfly valve) may be operated by a handle, a water separator valve used in a water supply drainage system is, as illustrated in FIG. 2, mostly inside the valve chamber 17 or the valve box 19. Since it is installed in the lower part, most of the key opening / closing valves operated by the metal (mainly cast iron or steel) valve key 23 are the same. The valve key 23 is composed of a key box 25 having a rectangular hollow, a handle 29 that can be held and turned by a worker, and a long stem 27 connecting the key box 25 and the handle 29. It is composed. Therefore, all the water valves operated by the valve key 23 have a valve seat 3, as shown in FIG. 2, and the upper side of the valve seat 3 has a key box () of the valve key 23. The metal valve cap 5 in which the square head 7 inserted into 25 is detachably joined. Although only the front view of the gate valve connected to the piping 15 was shown in figure, the butterfly valve also has the metal valve cap 5 the same point.

Most tap water valves are buried underground. If the distillation valve or piping is installed shallowly from the ground, the distillation valve or the piping may be damaged by the pressure or shock applied from the ground, so the valve chamber should be as low as 1 ~ 2m and as deep as 8 ~ 10m. (17) or the valve box 19 is provided, and a water separator valve is installed there. If the valve chamber 17 is wide and an operator can enter and exit, it also serves as a manhole function, and the ground opening is closed with a manhole cover at this time. However, as shown in FIG. 2, when the valve chamber 17 is narrow or when only the valve box 19 is installed without the valve chamber, the operator cannot enter or exit the interior, and the ground opening is closed by the drawer 21. . Since the space where the distillation valve is installed is a valve chamber or a valve box in the ground, water and earth and sand are easily introduced around the distillation valve and are dark even during the day because there is no separate lighting.

The water pressure at each point in the water supply network is significant in terms of water management. For example, if the water pressure at any point is too low, it can be determined that there is a leak in the water supply pipes nearby. Water pressure measurement is also essential in determining the replacement time of pipes and in determining whether they require repairs. In particular, the water pressure should be maintained at an appropriate level in the final water phase stage, the pressurization stage or the intermediate stage. In addition, the water pressure needs to be measured also in the case of temporary regional separation of the water supply pipe, the establishment of the water supply pipe, the opening and closing of the water valve for maintenance and cleaning of the water supply pipe, and the like.

In the conventional water supply network, the water pressure measurement is performed by connecting a separate pipe that can be combined with a water pressure gauge between the water supply pipes, and forming a manhole around the water supply manager. lost. However, when leak checks are frequently required, when there are a large number of points where water pressure measurement is required, and when new pipes are frequently constructed or abolished, water pressure measurement by such a method is very cumbersome.

The water supply network is equipped with a water valve to separate the network into small and large compartments for each element. Therefore, if the water pressure measurement at each distillation valve can be facilitated, management of water supply operation can be very easy.

The present invention has been made to solve the above-mentioned problems in the operation management of the conventional water supply network, the first problem to be solved by the present invention is to easily measure the water pressure on the ground whenever the water management manager is required at the point where the water valve is installed. The present invention provides a smart distillation valve capable of measuring water pressure and wirelessly outputting water in a pipe.

The second problem to be solved by the present invention is to provide a smart water valve capable of measuring the pressure and wireless output can minimize the power consumption of the water pressure meter and the pressure transmitter installed in the water valve.

A pressure transmitter configured to receive a date and time and store the received pressure and measurement date and time in a memory under a predetermined condition and to control the radio frequency transceiver to transmit a microcontroller unit; It is installed in a portable terminal, and synthesizes a radio frequency transceiver for receiving water pressure and measurement date and time from the water pressure transmitter, a memory for storing the received water pressure and measurement date and time, and the water pressure and measurement date and time received by the radio frequency transceiver. It is solved by a smart dilution valve capable of hydraulic pressure measurement and wireless output, comprising; a hydraulic pressure receiving output unit consisting of a hydraulic pressure display device for outputting a voice or text to the outside by text or text.

The second object of the present invention described above further includes a trigger switch that is triggered by light, magnetic field, or impact on the hydraulic pressure transmitter, and the light, magnetic field, or impact is applied to the trigger switch. Only when the microcontroller unit of the hydraulic pressure transmitter is controlled so that the power of the hydraulic pressure gauge is turned on, and the radio frequency transceiver of the hydraulic pressure transmitter transmits the hydraulic pressure and the measurement date and time.

According to the present invention, since the water pressure can be easily measured and confirmed in a number of dilution valves installed in the water supply network, the water supply operation manager can easily find a leak point on the water supply network, and the constant conditions on the ground (by the user) The hydraulic pressure and measurement date and time can be received and output from the mobile terminal simply by applying a valve cap shock, flash irradiation, or magnet access, so that the hydraulic pressure can be easily obtained, and constant conditions (valve cap shock by the user) can be obtained. , Flash irradiation, magnet access, etc.), the pressure gauge and the pressure transmitter stop the power consumption, so the power consumption is reduced to minimize the power consumption of the pressure gauge and the hydraulic transmitter installed in the water valve There is.
