Remote control intelligent pre-filter water meter system

Abstract

The invention discloses a remote control intelligent pre-filter water meter system which comprises a shell. A filter screen is arranged on the inner surface of the shell, pipelines are arranged on thetwo sides, corresponding to the filter screen, of the side wall of the shell in a penetrating mode respectively, the pipelines are communicated with the shell respectively, the pipeline on one side is fixedly connected with a throttler. The throttler comprises a main body, the main body is cylindrical, a connecting pipe is arranged on the side wall of the main body in a penetrating mode. Througharranging the main body, a movable pipe is arranged in the main body, a through hole is formed in the end face of a movable rod, a first control valve is used for adjusting the size and time of waterflow flowing through a filter screen. Through arranging an arc-shaped pipe on the connecting pipe, when the water flow is large, the water flow enters the main body through the arc-shaped pipe, so that the movable pipe moves, the water flow is reduced, the water flow can be automatically controlled, the hydraulic push rod can be remotely controlled to push the movable pipe through the arranged hydraulic push rod, the main body is completely blocked, and remote closing is achieved.

Description

technical field [0001] The invention relates to the technical field of water meter devices, and the specific field is a remote-controlled intelligent pre-filter water meter system. Background technique [0002] Water meters are used for water meters and are instruments 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-type water meters. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. When selecting water meter specifications, 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] The internal structure of a traditional water meter can be divided into three parts: the shell, the sleeve and the inner core from the outside to the inside. The shell is made of cast iro...

AI Technical Summary

Problems solved by technology

[0004] However, in view of the poor installation environment of some water meters, the sundries in the water will damage the internal structure of the water meter during long-term use, so it is necessary to design a pre-filter installed in front of the water meter to filter the water quality
