[0005] The existing rotor-type water meters basically follow the designs of Italy and Germany in the 1940s. Although some water meter companies have made breakthroughs in the range ratio and sensitivity of water meters in recent years, due to pipeline pressure fluctuations and air compression in tap water and The phenomenon of water meter rotation without water caused by tension has not been well resolved. The idling of the water meter has caused great losses to the user, so that the user often has conflicts with the water company, and even petitions to the higher-level government. , seriously affected social harmony

Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings, and the protection scope of the present invention is not limited to the following:
[0033] like figure 1 , 8 , 9, a two-way metering water meter, which includes a gear box, an impeller box, a counter and a stepped shaft 1. The bottom of the stepped shaft 1 is provided with a stepped hole 2, and a bushing 3 is arranged in the stepped hole 2. The bottom is provided with a spherical groove 4 , the upper and lower ends of the stepped shaft 1 are respectively equipped with gears 5 and a plurality of impellers 6 , and the plurality of impellers 6 are evenly distributed on the stepped shaft 1 .
[0034] like figure 2 and image 3 As shown, the gear box consists of a box body I7, an annular table 8 and a deceleration rib A12, the annular table 8 is arranged on the bottom surface of the box body I7, a cavity I9 is arranged in the box body I7, and a column platform is arran...

The invention discloses a two-way metering water meter, which comprises a gear box, an impeller box, a counter and a stepped shaft (1), the ring platform (8) of the gear box is inserted on the sinking platform (20) of the impeller box, the stepped shaft ( 1) Vertically set and the top of the stepped shaft (1) passes through the through hole (11), the stepped shaft (1) is fitted on the fixed shaft (14) through the bushing (3) and installed on the fixed shaft (14), and the pointed The top of the cone (18) is in contact with the spherical groove (4), the gear (5) and the counter are set in the cavity I (9) and the gear (5) is meshed with the input end of the counter, and the impeller (6) is set in the cavity I (9). In the chamber II (16), the upper end surface of the impeller (6) is flush with the lower end surface of the water outlet (21). The invention has the beneficial effects of: realizing the bidirectional measurement of the fluid by the water meter; high measurement accuracy and low manufacturing cost.
Description
technical field [0001] The invention relates to the technical field capable of measuring the flow of forward fluid and the flow of reverse fluid, in particular to a bidirectional metering water meter. Background technique [0002] Rotor-type water meter is the most widely used tap water measuring instrument at present. It has the characteristics of simple structure, low manufacturing cost and stable product quality. Civil and industrial water meters of multiple calibers including DN13~DN150. Including the smart water meters and remote-controlled network water meters that have appeared in recent years, the water meters with this structure are used as the base meters. [0003] The rotor-type water meter structure is divided into an indicating part and a metering part. The indicating part is composed of several groups of gears and word wheels for users and manufacturers to read the water meter numbers, also known as counters. There are three types of counters that are most us...
