Description
Technical field:
The utility model relates to the water meter field, relates to a kind of device that is used to improve the water meter measurement precision specifically.
Background technology:
The existing measuring apparatus that is used on the water supply line mostly is by gear-driven water meter, and the water meter of this structure measures inaccurate not even metering when the weep water, especially more like this on family water pipe road.Learn that through experiment a water meter does not measure when enough weeps supply water, the 100-300 kg of water that whenever can run off round the clock, this has just run counter to the fairness doctrine, is unfavorable for water resources management, causes damage to national wealth.
The utility model content:
The purpose of this utility model provides a kind of device that is used to improve the water meter measurement precision with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can be achieved through the following technical solutions:
The utility model comprises the water containing chamber that has inlet tube and outlet tube, is provided with a locating rack in described water containing chamber, and the water delivering orifice of described water inlet pipe is connected with described locating rack; Water delivering orifice place at water inlet pipe is provided with a retaining valve; On described locating rack, be provided with the telescopic tube that a sidewall has step in movingly mode; On described water containing chamber sidewall, be provided with a power cavity corresponding to described water inlet pipe water delivering orifice position, in described power cavity, be provided with an elastic baffle it is divided into upper and lower two chambers, described upper chamber is connected with water containing chamber, and described lower chambers is provided with a connecting pipe; Be provided with a push rod in upper chamber, the other end of described push rod passes described telescopic tube and extends near described water inlet pipe water delivering orifice position; In upper chamber and on the push rod between the inside and outside sleeve pipe of described telescopic tube, be set with stage clip, described push rod and inner sleeve Joint; The water delivering orifice of water inlet pipe and the locating rack between the telescopic tube are provided with register pin; Be hinged with an expansion link on locating rack, the lower end of described expansion link extends on the step table top of telescopic tube; Be communicated with a shunt valve on the water inlet pipe of water containing chamber being positioned at, the water delivering orifice place of described shunt valve is provided with a retaining valve, and the valve rod of described retaining valve extends to the place, step top position of telescopic tube.
For reducing friction, be provided with a roller in the lower end of institute's expansion link.
After advantage of the present utility model just is to adopt said structure, during use described water inlet pipe is connected with the water meter outlet, water delivering orifice connects water pipe, and described communicating pipe is connected by three-way pipe with the water meter water inlet pipe.When not making water, be full of water in the water containing chamber, the upper and lower cavity chamber pressure in the power cavity equates that the stage clip and the elastic baffle that are arranged in the power cavity produce balance between two forces, push rod is failure to actuate; When weep made water, the chamber up and down in the power cavity produced pressure reduction, impelled elastic baffle to drive on push rod, the inner sleeve and moved, and outer tube is moving on simultaneously under the effect of inner sleeve and stage clip, and described draw-tube is compressed.When the outer tube top moves to described alignment pin position, the outer tube stop motion, and inner sleeve is moving on the described stage clip of continuation compression under the effect of push rod, at this moment the relative motion owing to inside and outside sleeve pipe diminishes until disappearance the step table top that is opened on its sidewall, the lower end of described expansion link is slipped to automatically on the valve rod that is arranged on shunt valve water delivering orifice place retaining valve its unlatching is supplied water in water containing chamber, impels water meter to begin metering; At this moment because the interior water outlet of water containing chamber is intake many less, the hydraulic pressure of chamber up and down in the power cavity reaches equal gradually, driving push rod under the effect of elastic baffle stage clip in being arranged on upper chamber moves down, inside and outside sleeve pipe also moves down successively, the table top of described step forms again, and when telescopic tube was displaced downwardly to initial position, the expansion link lower end was slipped on the table top of described step again voluntarily, the shunt valve water delivering orifice is closed and is stopped to supply water in water containing chamber, and water meter stops metering.Because the weep water continues, this device can repeat above-mentioned action, so that intermittently quantitative water supply metering of water meter, measures inaccurate even non-metering problem thereby solved water meter when the weep water.When big current water, this device is in like manner opened the shunt valve water delivering orifice and is supplied water to water containing chamber, because shunt valve institute insufficient water is to satisfy the needs of big current water, hydraulic pressure in the water containing chamber is still relatively low, elastic baffle continues to promote to move on the described push rod, until opening the retaining valve that is arranged on water inlet pipe water delivering orifice place water inlet pipe is poured water to water containing chamber, water meter normally measures, and has guaranteed normal water.
