Embodiment Construction

[0018] Combine below Figure 1-4 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.

[0019] combined with Figure 1-4 The described indoor safety pressure relief gas pipeline includes a gas pipeline 10, the lower end of the gas pipeline 10 is fixed with a collection block 38, and the gas pipeline 10 is provided with an air pressure sensing mechanism 70 for sensing the air pressure in the pipe. The block 38 is provided with an air pressure collection collection 71 for collecting and releasing pressure. The left end of the collection block 38 is provided with a gas discharge mechanism 72 for selectively discharging gas. The upper inner wall of the gas passage 22 is provided with a pressure sensing chamber 19 with an opening downward, and the pressure sensing chamber 19...

Abstract

The invention discloses an indoor safety pressure relief fuel gas pipeline which comprises a fuel gas pipeline body. A collecting block is fixed to the lower end face of the fuel gas pipeline body; agas pressure sensing mechanism for sensing the gas pressure in the pipeline is arranged in the fuel gas pipeline body; a gas pressure collecting device for collecting and relieving pressure is arranged in the collecting block; a fuel gas discharging mechanism for selectively discharging fuel gas is arranged at the left end of the collecting block; and when the gas pressure in the fuel gas pipelineis too large, a sensing block in the pipeline senses pressure intensity changes and automatically starts a pressure relief function, redundant fuel gas can be automatically collected in the pressurerelief process, and when the collected fuel gas is too much, a standby pressure reduction function is automatically started, so that stable pressure relief and pressure intensity balance of the fuel gas pipeline are further guaranteed, the collected fuel gas can be refilled into the fuel gas pipeline or taken out to be treated separately, and the process can be guaranteed to be carried out safelywhile pressure relief is carried out on the fuel gas pipeline.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to an indoor safe pressure relief gas pipeline. Background technique [0002] Gas is a common combustible gas in daily life. Gas needs to be transported by pipelines. Gas transmission pipelines have different compression characteristics according to different materials. When the compression resistance limit of the pipeline is exceeded, it is easy to bleed and rupture and cause gas leakage. [0003] At present, the general gas transmission pipeline does not have the function of gas high pressure detection and automatic pressure relief. Generally, a pressure relief valve is installed separately, so the pressure in the pipeline cannot be adjusted through the pipeline itself, and the gas collected after pressure relief cannot Dispose of it separately or return it to the pipeline. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an i...
