Rotor highly sensitive water gauge

Abstract

The invention provides a rotor high-sensitivity water meter, comprising a meter cover, a rotor measuring mechanism arranged at the lower part of the meter cover, and an upper indicating mechanism corresponding to the rotor measuring mechanism; an impeller box in the measuring mechanism is of a round-basin shape, and an adjusting board is arranged at the bottom of the impeller box, meanwhile, the impeller is arranged at a fixing support center, and a filtering net is arranged outside the impeller box; a round filtering cylinder which is concave downward is arranged at the lower part of the filtering net, and a guide shaft is arranged at the bottom of the filtering net at the outer circumference of the round filtering cylinder, and a water-sealing valve which can move up and down is ringed on the guide shaft; a squared strip which is tightly matched with the impeller box is arranged at the inner wall of the filtering net; a water hole is arranged in the squared strip, and a jet hole is provided at the position of the impeller box with which the water hole is connected. The water meter has the advantages that a water-sealing valve is arranged on the base of the prior common water meter, and the filtering net adopts a round filtering cylinder to greatly increase the water flow of the filtering net, therefore, the pressure loss of the rotor high-sensitivity water meter is reduced.

Description

Technical field: [0001] The invention relates to a rotor type water meter with a nominal diameter of 15mm to 50mm Background technique: [0002] At present, the water meters used in my country's water supply departments are generally ordinary rotor-type water meters. When the water flow is less than the dynamic flow (the nominal diameter of a 15mm water meter is 10l / h, the larger the diameter, the higher the dynamic flow). When the water meter does not measure. As a result, many users take advantage of this and adopt the method of small flow or dripping water to achieve the purpose of not paying for water use. In response to this situation, the water supply department used some high-sensitivity water meters, but some water companies reported that after using the high-sensitivity water meters on the market, the water volume of users on the fifth floor and above became smaller, and even the water was not used during peak water consumption. Article 6 of the National Standard o...
