Problems solved by technology

[0002] At present, the existing household gas meters are generally installed on the living balcony. The household gas meter is connected with the gas main pipe through the gas branch pipe. Both the gas branch pipe and the gas main pipe are of steel pipe structure. There are more and more houses, and the living balcony and kitchen are often connected together during renovation. At this time, the gas meter and gas pipeline will be exposed outside, which is very ugly, and a lot of oily smoke will be generated in the kitchen, which will damage the gas meter. Corrosion will shorten the service life of the gas meter. In addition, in order to better facilitate the user to control the flow and shutdown of the gas, it is necessary to install a switch valve in the gas pipeline. This switch valve includes a switch valve and a switch valve handle. By rotating the switch valve The handle makes the spool in the on-off valve close or open the gas channel, so as to achieve the function of the on-off valve to control the flow and closure of gas. Most of the on-off valves on the market are manual valves, although the gas electric valves used in factories , but this kind of gas electric valve is not only costly, but also the electrical part is connected with the switch valve as a whole. Due to the flammable, explosive and unsafe characteristics of gas, the electric valve cannot be used safely in the family. The existing gas electric valve is not Good for home use

Abstract

The invention provides an intelligent remote pressure regulating and flow limiting system for fuel gas. The system comprises an upper computer, a programmable logic controller, an ER controller and apressure regulator, and the upper computer, the programmable logic controller, the ER controller and the pressure regulator are sequentially connected with one another; the upper computer issues an instruction for setting pressure, flow and valve opening, and the programmable logic controller receives the instruction issued by the upper computer and issues the instruction to the ER controller; andthe ER controller receives an instruction of the programmable logic controller and is in control connection with the pressure regulator. According to the system, the functions of remote current regulation, pressure regulation, emergency cut-off, remote monitoring and the like are realized; a gas distribution, protection and feedback control system with intelligent judgment and self-adaptive adjustment capabilities is constructed; the functions of unattended operation, remote monitoring, mistaken rushing alarm, unlocking and door opening alarm and the like are realized; bias current is solved,stable-pressure shunting is realized, flow is balanced, and single-path full-load operation is avoided; and an over-pressure or over-current protection function is realized.
