Abstract

The invention discloses a device for detecting the accuracy of a mechanical water meter. The device for detecting the accuracy of the mechanical water meter comprises a water meter detection operating platform rack, and plum blossom pointer rotating speed detection devices of which the number is the same as the number of water meters and the structures are the same as the structures of the water meters, wherein a water inlet end, a regulating valve, a plurality of standard water meters to be detected and a water outlet end are sequentially connected in series between one side and the other side of the upper surface of the water meter detection operating platform rack; a laser, a phototriode and a detection circuit are arranged in parallel on a base in a shell of each plum blossom pointer rotating speed detection device; the lower end of the base is connected with a sunshade; one end of a fixed clamp is connected with the sunshade, and the other end of the fixed clamp is connected witha dial plate of the corresponding water meter; observing windows are formed on the top cover of the shell and the side faces of the base; and the detection circuit of each detection device is connected with a data processing system. A photoelectric sensor is used for detecting a plum blossom pointer rotating speed, so the regulation accuracy of the water meter is enhanced and the working efficiency is improved; the cost is low; and the water meter can be regulated quickly on the industrial site so that the accuracy of industrial water metering can be enhanced effectively.

Description

technical field [0001] The invention relates to a measuring instrument for detecting liquid flow, in particular to a device for detecting the accuracy of a mechanical water meter. Background technique [0002] The accuracy of water meters has a direct impact on water measurement and plays a very important role in the rational use of water resources. In the process of manufacturers producing mechanical water meters, some products have inaccurate measurement of water consumption. This requires workers to adjust the measurement accuracy of the water meter by adjusting the adjusting screw at the back end of the water meter before leaving the factory and putting it into practical use. Make it meet the requirement of being able to measure water consumption accurately. [0003] There is no instrument specially developed for regulating water meters in our country. At present, the device for workers to adjust the water meter mainly uses the verification device in JJG 162-2009 "Cold...
