Transparent window with reed pipe sampling device, processing method of transparent window and special water meter

Abstract

The invention discloses a transparent window with a reed pipe sampling device, a processing method of the transparent window and a special water meter, and belongs to the technical field of reed pipe water meters. The transparent window mainly comprises a window body, the window body is made of transparent plastics, more than one reed pipe is arranged in the window body, the reed pipes are matched with a magnetic pointer of the water meter, and leads of the reed pipes extend out of the window body. According to the invention, the reed pipe and the lead are directly embedded into the transparent window made of the plastic material through a repeated injection molding process, so that the reed pipe meets the requirements of sealing and pressure resistance required by the use of the water meter, the production cost is reduced, the reed pipe is more convenient to replace, and the intelligent water meter with the reed pipe is easier to popularize and produce in batches. The transparent window is mainly used for the reed pipe water meter.

Description

technical field [0001] The invention belongs to the technical field of reed switch water meters, and in particular relates to a transparent window with a reed switch sampling device, a processing method thereof and a special water meter. Background technique [0002] With the continuous improvement of people's living standards, smart water meters gradually replace ordinary water meters and enter people's daily lives. Compared with ordinary water meters, smart water meters are more convenient for counting and data post-processing. Commonly used sensors for existing smart water meters include photoelectric sampling devices, Hall elements, and reed switches. Among them, reed switches are the most widely used as passive device sensors. They have low power consumption and long service life. The tube is used in conjunction with a pointer with a magnet, and the reed switch is used as a magnetic switch. With the rotation of the pointer, the reed switch is closed to obtain the corres...

AI Technical Summary

Problems solved by technology

Due to the high requirements of the water meter on the sealing and pressure resistance of the reed switch, it is usually necessary to perform sealing and pressure resistance treatment for the reed switch and its lead device, resulting in high production costs and low processing efficiency; and the lead device includes brackets and hair coils etc. The lead wire device occupies the space of the end cover of the water meter, which increases the height of the water meter and is not convenient for installation and use.

At the same time, the reed switch device is soaked in water all the year round, resulting in a high failure rate and inconvenient maintenance, which cannot meet people's use requirements

At the same time, the window of the water meter is usually a glass window, which has poor impact resistance and is prone to freezing and cracking in winter. Maintenance and replacement are time-consuming and laborious.
