Intelligent closing device for fuel gas vertical tube

Abstract

The invention relates to the technical field of fuel gas, in particular to an intelligent closing device for a fuel gas vertical tube. The intelligent closing device comprises the vertical tube and avalve body, wherein the middle part of the vertical tube is equipped with the valve body; the outer wall of the valve body is blocked with a dual-group type nixie tube; the left side of the bottom ofthe outer wall of the valve body is tin-soldered with a first signal lamp; the right side of the bottom of the outer wall of the valve body is tin-soldered with a second signal lamp; a gas inlet is formed in the bottom of the valve body; a gas outlet is formed in the top of the valve body; a flow meter is mounted on the middle part of the gas inlet; and the left side of the bottom of the valve body is tin-fixed with a gas pressure meter. The flow meter is positioned in the gas inlet for monitoring gas flow at the gas inlet, and the gas flow is displayed through the nixie tube; if the gas flowis within a controlled range, the first signal lamp is a green lamp, otherwise, the first signal lamp is a red lamp. The intelligent closing device is convenient for timely managing and monitoring usage amount of fuel gas in the fuel gas vertical tube in a house, avoids fuel gas particles and is suitable for being widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to an intelligent closing device for a gas riser. Background technique [0002] The gas pipe has the characteristics of convenient installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas resistance. The material of the surface soft protective layer is safer, easier to clean, and more beautiful. The service life of the stainless steel threaded metal hose is 8 years. [0003] At present, the gas riser is usually the low-pressure inlet pipe of the building, which is connected to each user's home by the tee on the riser, and the control switch of the existing gas riser is more limited, which is not conducive to the family's attention and timely management. Therefore, we propose a gas riser intelligent closing device, which is convenient for timely management and monitoring of the g...
