Description

Freeze protection device of water meter {ANTI-FREEZING DEVICE FOR WATER GAUGE}

The present invention relates to a freeze protection device of a water meter, and in particular, a digital meter, a pressure reducing valve, and a water pipe are enclosed on both sides by having a main body on both sides that divides the meter seating chamber, the pressure reducing seat seating chamber, and the water pipe seating chamber into two parts. Oh, it can be seated, and the outer periphery of the main body of both sides is combined with the protection packs of both sides forming a nitrogen-filled layer filled with nitrogen therein, and the outer periphery of both protective packs to form a plurality of locking pieces on one outer peripheral surface On the other outer periphery, the case has two wires that form a plurality of hooks, and then it has a wire that connects the digital meter and the computer. Connected to an external computer, and the main body on both sides is In addition, the water pipe is primarily insulated, and secondly, the insulation is made by the nitrogen-filled layers of both protective packs, which are coupled to the outer circumferential surface of the main body, so it is possible to effectively prevent freezing and open the lid of the meter box to check the value of the meter. Since it is possible to check the numerical value through a monitor such as an external computer without the need, the intrusion of outside air becomes impossible, and it relates to the freezing prevention device of a water meter which can conveniently check the numerical value even in a cold season without freezing accident.

In general, the water meter checks the inflow rate of the water supply to each household, apartment, multi-family house, multi-family house, water tank and water tank and collects the charges in proportion to the displayed usage number.

If the water temperature-related facility lasts for a long time (usually more than 48 hours at -3 ℃ ~ -5 ℃) when the temperature in winter falls below freezing point (0 ℃), the water meter and water facilities exposed to the outside air freeze, Occurs frequently.

The above-mentioned freezing phenomenon is mostly frozen from a part of the water pipes and peripherals, and the water flow is stagnated, and the freezing starts as a whole.

In order to prevent the above phenomenon, it is common to construct a heat insulating material, a constant temperature wire, a heating wire, and the like.

The freeze protection device for the water meter has been researched and developed in various ways, but since the water meter has been neglected in terms of damages such as leakage due to freezing accidents, water meter accidents increase.

Cold weather due to extreme weather in winter is happening without notice. Accordingly, the freezing of water meter is increasing according to the law. And the cost of leaks, and the inconvenience and financial loss caused by the shortage during the replacement and repair periods are increasing, but there is little countermeasure against freezing due to the sudden change in the weather. to be.

The current countermeasures have been taken to prevent freezing by insulating insulation, heating, clothes, etc., or by flowing tap water.

Conventional freeze protection devices as described above are mostly installed on the basement and corridor walls.

Water meter installed underground has caused a lot of problems to prevent freezing, such as the heat insulating material is frozen due to moisture condensation due to moisture condensation, and short circuit and disconnection of the heating wire by moisture.
