Leakage self-reminding ring at natural gas pipeline connectors

Abstract

The invention discloses a leakage self-reminding ring at natural gas pipeline connectors, and belongs to the field of natural gas leakage prevention. The leakage self-reminding ring at the natural gaspipeline connectors comprises a ring body connected to the two natural gas pipeline connectors, wherein through the arrangement for the ring body, when natural gas leakage occurs, on one hand, a gasseal ring is expanded under the extrusion of natural gas, so that the contact area of the gas seal ring and the surface of the natural gas pipeline is increased, a better sealing effect is achieved, and then more obvious phenomenon occurring outside the ring body is effectively ensured, and a better reminding effect on a user is achieved; and on the other hand, a pneumatic diaphragm is deformed outwards, and then self-connecting net rods are driven to protrude out of a limiting plate in sequence from the middle part to the edge; and a plurality of adjacent hollow top balls and flexible adsorption bars are mutually connected in an adsorption manner to form a net surface structure, so that the self-reminding phenomenon is further enhanced, the probability that the user finds natural gas leakage in time is effectively increased, maintenance is facilitated, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of natural gas leakage prevention, in particular to a self-alerting ring for leakage at the interface of a natural gas pipeline. Background technique [0002] Natural gas is stored in underground porous rock formations, including oil field gas, gas field gas, coal bed methane, mud volcano gas and biologically generated gas, etc., and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material. [0003] The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular weight hydrocarbons and non-hydrocarbon gases. [0004] It is mainly composed of methane (85%) with small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). It is mainly used as a fuel, and is also used as a r...

AI Technical Summary

Problems solved by technology

[0005] The natural gas pipeline interface is prone to aging after long-term use, and there is a possibility of gas leakage. When the leakage of natural gas is small, it is difficult to find it. Due to its flammability, there is a greater safety hazard
