Water meter and processing technology thereof

Abstract

The invention discloses a water meter and a processing technology thereof. The water meter comprises a meter shell, an impeller, a metering box, a demisting rod group, a lower sealing ring, meter glass and an upper sealing ring, a gear set, a connecting column and a plurality of pointers are arranged in the metering box; the demisting rod group comprises a supporting piece, a supporting spring, a supporting rod, a first scraping rod, a second scraping rod, a stand column and a first bevel gear; a smooth groove is formed in the lower portion of the first scraping rod; the tops of the first scraping rod and the second scraping rod are in contact with the lower surface of the meter glass; the stand column is rotatably connected with the lower sealing ring; the tail end of the supporting rod is located in the smooth groove; and the areas, located below the meter glass and above the metering box, in the meter shell are filled with prepared liquid such as glycerin. The demisting rod group is arranged at the bottom of the meter glass, so that the effect of removing mist on the meter glass in a larger area is achieved through the movement of the first scraping rod and the second scraping rod and the supporting force of the spring and the supporting sheet during use, and a meter reader is ensured to accurately read a water consumption value.

Description

technical field [0001] The invention belongs to the technical field of water meters, in particular to a water meter and its processing technology. Background technique [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. , you should first estimate the size and flow range of the flow normally used, and then choose the water meter of the specification with the usual flow closest to the value as the first choice. [0003] In southern my country, wet water meters are generally used to record water consumption. Because the existing water meters are used in a relatively humid environment, after a period of use, fog will condense in the glass window of the water meter, making it difficult for the recorder to see the ...

Problems solved by technology

[0003] In southern my country, wet water meters are generally used to record water consumption. Because the existing water meters are used in a relatively humid environment, after a period of use, fog will condense in the glass window of the water meter, making it difficult for the recorder to see the readings of the water meter. , thus causing great hindrance to the recording personnel's work; after searching the existing patents, there is a technical solution for using a brush plate to clean the fog in the glass window. This type of solution uses a single brush plate to swing back and forth for cleaning, and its swing angle Affected by the size of the glass window, the cleaning range is limited, and the area where the water meter needle is located cannot be completely defogged. There are still great obstacles for the meter reader to record
