High pressure resistant water meter housing

Abstract

The utility model relates to water meter technical field, concretely is a kind of high-pressure-resistant water meter shell, connecting unit includes the connector one of fixed setting on inlet pipe, the output end of outlet pipe is fixedly provided with drain pipe, cavity one is opened in shell, the upper end of cavity one is opened with cavity two, connecting pipeline is fixedly set on drain pipe, after device is connected, water flow can pass through the buffer of cavity one and reduce the pressure of device shell, in circulation cavity two, the shaft body on the outer circumferential surface of the rotating shaft and the drainage plate fixedly set on the rotating shaft outer circumferential surface in connecting pipeline can be driven rotating shaft rotation by water flow, rotating shaft can drive the shaft body on its outer circumferential surface rotation, rotating shaft body can pass through the guide groove on its outer circumferential surface control and reciprocatingly move the sliding block sliding connection between it, can be cleaned by the scraper fixedly connected between it in the process of sliding block movement and the impurity adhering on the inner wall of connecting pipeline, ensure the flowability inside device.
