Embodiment 1

[0055] like figure 1 As shown, a gas safety monitoring system according to the present invention includes a pressure detection valve 1 , an entry valve 4 and a background management center 5 . The entry valve 4 is arranged on the entry pipe of the gas pipeline to control the on-off of the entry pipe and the supply of gas. One end of the pressure detection valve 1 is connected to the indoor pipeline of the gas pipeline, and the other end is connected to the household pipeline. The pressure detection valve 1 is used to detect the abnormality of the air supply pressure of the indoor pipeline, and then judge whether leakage or abnormal air supply occurs. The pressure detection valve 1 is wirelessly connected with the entry valve 4 . The background management center 5 interacts with the pressure detection valve 1 and the entry valve 4 respectively based on wireless network communication.

[0056] Wherein, the pressure detection valve 1 is provided with a mechanical automatic clo...

Embodiment 2

[0071] The safety monitoring system for gas use described in Embodiment 2 is similar in structure and principle to Embodiment 1. Specifically, the structure of the pressure detection valve is described in detail:

[0072] like figure 2 As shown, specifically, the pressure detection valve 1 includes a valve body, a diaphragm 11 , a first pressure balance mechanism 3 and a second pressure balance mechanism 2 . The diaphragm 11, the first pressure balance mechanism 3 and the second pressure balance mechanism 2 jointly constitute a mechanical automatic closing device.

[0073] Wherein, the diaphragm 11 divides the chamber of the valve body into an upper chamber 12 and a lower chamber 13 that are not connected to each other; the lower chamber 13 is provided with two gas ports; the first pressure balance mechanism 3 Placed in the upper chamber 12 and connected with the diaphragm 11; the second pressure balance mechanism 2 is straddled between the lower chamber 13 and a gas interfa...

Embodiment 3

[0096] The safety monitoring system for the use of gas described in Embodiment 3 is similar in structure and principle to Embodiment 1. Specifically, the entry pipeline 4 is described, and the entry valve 4 is a pipeline solenoid valve. The structure is as follows:

[0097] The entry valve 4 is the pipeline electromagnetic valve 4 , which includes a hollow pipe body 41 , a sealing assembly 42 and an electromagnetic driving assembly 43 .

[0098] like image 3 As shown, specifically, the inner wall of the hollow tube body 41 has a stepped structure, so that the inside of the hollow tube body 41 has a first cavity and a second cavity parallel to each other. Both the first cavity and the second cavity are cylindrical cavities, and the diameter of the first cavity is larger than that of the second cavity; the boundary plane between the two is the stepped platform of the stepped structure, which is an annular .

[0099] In this embodiment, preferably, the stepped platform is pro...

Abstract

The invention discloses a safety monitoring system for gas utilization. The safety monitoring system comprises a pressure detection valve, a home-entry valve and a background management center. The pressure detection valve is connected with a home-entry pipeline and an in-home pipeline of a gas pipeline and is provided with a mechanical automatic shutoff device, and the mechanical automatic shutoff device is automatically shut off so as to isolate the home-entry pipeline and the in-home pipeline when the gas supply pressure of the in-home pipeline is lower than a set value. The home-entry valve is arranged on the home-entry pipeline of the gas so as to control on-off of the home-entry pipeline. The home-entry valve is electrically connected with the pressure detection value. When the pressure detection value detects that the gas supply pressure in the in-home pipeline is lower than the set value, the home-entry valve is instructed to shut off the home-entry pipeline. The background management center is connected with the pressure detection valve. When the pressure detection value detects that the gas supply pressure in the in-home pipeline is lower than the set value, the background management center transmits alarm information to a user terminal. Gas utilization of users is intelligently monitored and protected.

Description

technical field [0001] The invention belongs to the technical field of gas safety use, and in particular relates to a safety monitoring system for gas use. Background technique [0002] In recent years, the national gas industry has developed rapidly, and gas such as liquefied petroleum gas, natural gas, and coal-based gas have been widely used in industry and commerce as clean energy. However, with its wide application, improper use or leakage of these gases will be harmful to health, prone to explosion, and many hidden dangers and accidents. If the gas leaks cannot be detected and dealt with in time, it will bring catastrophic harm to the society and residents. To some extent, it has increased the city's insecurity and instability. [0003] For gas safety management and prevention, existing safety monitoring systems generally use a single gas detection sensor to detect whether gas leakage occurs. However, the use of gas sensors generally has a drawback, which is that it ...
