Intelligent buried gas metering device

Abstract

The invention relates to an intelligent buried gas metering device. The intelligent buried gas metering device comprises a box body with an opening in the top, wherein an upper cover is hinged to thetop of the box body; a transparent window plate is fixedly connected to the upper part of the box body in a sealing manner; an inlet connecting pipe is fixedly connected to and communicates with one side of the box body; an outlet connecting pipe is fixedly connected to and communicates with the other side of the box body; a metering unit and a detection unit are fixedly connected to the inner part of the box body; the box body also communicates with an emptying pipe; the gas inlet end of the metering unit communicates with the inlet connecting pipe; the gas exhaust end of the metering unit communicates with the outlet connecting pipe; the metering unit comprises an inlet fixing seat, an outlet fixing seat, a vertical pipe, a flow meter and an IC card controller which are fixedly arrangedon the inner wall of the box body; the gas inlet end of the flow meter is fixedly connected with the inlet fixing seat; the gas exhaust end of the flow meter communicates with the IC card controller;the IC card controller is fixedly connected to and communicates with the outlet fixing seat; and the vertical pipe is fixedly supported at the bottom of the gas exhaust end of the IC card controller.According to the metering device, buried gas metering detection can be realized, and an extra power supply does not need to be designed for numerous instruments and meters; and the intelligent buriedgas metering device is compact in structure and safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of gas transmission and distribution, in particular to an intelligent buried gas metering device. Background technique [0002] Most of the traditional domestic gas metering devices are arranged on the ground, and the valves, filters, meters, etc. are connected in sequence through pipelines inside the box. There are following defects in this filter box: [0003] 1. It takes up a lot of space and is complicated to maintain. [0004] 2. The ground inside some cabinets is damp and poorly ventilated, and the equipment used is easily corroded, posing potential safety hazards. [0005] 3. Most of the metering devices are arranged next to the road, which is easy to block the line of sight, and the uncivilized behavior of some passers-by makes the surface of the box obviously scratched and stained, which affects the appearance. [0006] 4. There is a risk of gas leakage caused by being hit by a vehicle. [0007]...
