Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with embodiment (accompanying drawing):

[0021] like figure 1 , 2 , 3, the micro-flow starting water meter of the present invention includes a water meter body, and a diverter is installed in the lumen of the water inlet nozzle 6 of the water meter, and the diverter includes a static A tubular housing 5 combined in a mating manner. The lumen of the tubular housing 5 is divided into two cavities, the front and the rear, by the annular shoulder processed in the lumen, and a communication channel is opened on the wall of the lumen at the rear section. The normal water outlet hole 4 of the inner cavity of the water meter; a piston valve body 14, a pressure spring 16 set outside the valve body and a valve core 17 worn in the inner cavity of the valve body are installed in the rear section of the tube cavity; the valve body 14 A plurality of micro-flow water inlet holes 15 communicating with the...

Abstract

The invention relates to a micro flow drinking water meter which comprises a water meter body. It is characterized in that a circular is fixed inside the pipe of the inlet (6) of the water meter; the circular comprises pipe-type casing (5) which is bonded with the internal wall of the water meter inlet by tight fit mode, the pipe cavity of the pipe-type casing is divided into a front cavity and a rear cavity by a ring form shoulder; the wall of the rear cavity possesses a water outlet hole (4) which is connected with the water inner cavity; the rear cavity possesses a piston-type valve body (14), a pressure spring (16) covered with the valve body, and a valve core (17) inside the valve body; the water face of the valve body (14) possesses multiply micro flow inlet holes (15) which are connected with the valve inner cavity; the valve core possesses an axial flow path whose end is through the micro flow guide pipe (8) and is connected with the water meter guide shell (2); the flow value control valve is positioned on the front end of the flow path.

Description

technical field [0001] The invention relates to a tap water meter, in particular to a micro-flow starting tap water meter used for business settlement. Background technique [0002] At present, the widely used ordinary water meters are all manufactured according to the national standard GB778-1984. Because of the large initial flow, in actual use, not only cannot meet the requirements of meter reading charges and commercial settlement, but also cannot It is suitable for work needs such as preventing pipeline leakage, preventing a few people from deliberately stealing water, and saving water. Based on the above reasons, in recent years, many units have begun to develop a wide variety of water meter products with small initial flow, which are customarily called "anti-drip water meters". It is a representative type of this type of water meter. Although this type of anti-drip water meter has obvious anti-drip effect compared with traditional water meters, most of these technol...
