Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0021] Referring to Figure 1, the inclined impeller direct reading water meter is mainly composed of inclined impeller 5, rectifier 6, adjustment device 8, counting mechanism with photoelectric direct reading sensor 2, bracket 4, watch case 3, watch cover 1 and filter screen 7, etc. The rectifier 6 is connected with the watch case 3 through the bracket 4, and the filter screen 7 is covered on the rectifier 6.

[0022] 2 and 3, it can be seen that the impeller of the metering mechanism is an inclined impeller 5, and the blades 53 and the impeller shaft 52 on the inclined impeller 5 are arranged obliquely. The blades 53 are composed of 12 pieces. The included angle is 26°, and the impeller shaft 52 of the inclined impeller 5 is equipped with a circular magnet 51, and the rotation number of the inclined impeller 5 is transferred to the counting mechanism 2...

Abstract

This invention provides one incline wheel read water meter, which comprises meter shell, incline wheel, integral device, rack, filter net, read structure and cover. This invention is characterized by the following: integral slice shape is of tamper with fix adjust device T tank on bottom part; integral device is connected to rack and filter net; incline wheel axis is fixed with round ring magnetic iron for metering through round ring magnetic iron; meter structure is fixed with light read sensor for water volume data.

Description

technical field [0001] The invention belongs to inclined impeller water meters and relates to the technical field of water meters. Background technique [0002] At present, most of the large-caliber water meters used for water supply are rotor type and horizontal screw type water meters. The sensitivity of the rotor type water meter is better than that of the screw type water meter, but the pressure loss is large, the volume is large, and the installation and maintenance are inconvenient. The horizontal screw-wing water meter has small pressure loss, small size and light weight, but its sensitivity is poor. Although various performances of the improved vertical screw-wing water meter have been greatly improved, the manufacturing cost is relatively high. Contents of the invention [0003] Aiming at the shortcomings of the existing large-diameter water meters, the invention provides a direct-reading water meter with inclined impellers, which improves the processing technolo...
