Multifunctional water meter capable of detecting and filtering

Abstract

The invention belongs to the field of water and electricity water meters, and provides a multifunctional water meter capable of detecting and filtering. The multifunctional water meter comprises a main control box; a water inflow pipe is arranged on one side of the main control box; a water outflow pipe is arranged on the other side of the main control box; a display module is mounted at the top of the main control box; a backflow prevention device is mounted in the main control box; two sides of the backflow preventing device are connected with the water inflow pipe and the water outflow pipe respectively; a filter plate is arranged in the backflow preventing device; a fixing device is arranged between the backflow preventing device and the filter plate. The backflow preventing device is additionally arranged, so that a water meter can accurately control the flow direction of water, and the situation that the water meter cannot accurately meter the water due to backflow of the water can be prevented; and meanwhile, the fixing device and the filter plate are additionally arranged, so that water flow passing through the water meter can be filtered, the fixing device enables the filter plate to be convenient to disassemble and assemble, and convenience is brought to replacement work of the filter plate.

Description

technical field [0001] The invention belongs to the field of hydropower water meters, in particular to a multifunctional water meter capable of detecting and filtering. Background technique [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. , you should first estimate the size and flow range of the flow normally used, and then choose the water meter of the specification with the usual flow closest to the value as the first choice. [0003] Most of the existing multifunctional water meters do not have the function of preventing backflow, and the backflow of water will cause the water meter to rotate, affecting the accuracy of measurement. At the same time, the water meter with filtering function will cause the...

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a multifunctional water meter that can detect and filter, aiming to solve the problem that most of the existing multifunctional water meters do not have the function of preventing backflow, and the backflow of water will cause the water meter to rotate, affecting the accuracy of measurement, and at the same time The water meter with filtering function will cause the filter plate to be blocked after being used for a long time. If it is not disassembled and cleaned in time, the water flow will not be smooth. However, most of the existing water meters have the filter plate fixed inside the water meter, which is not conducive to the removal of the filter plate. pretending problem
