Description

Natural gas steady voltage pipeline high pressure alarm device Technical Field The utility model relates to the technical field of natural gas pressure-stabilizing pipelines, in particular to a high-pressure alarm device for a natural gas pressure-stabilizing pipeline. Background Natural gas refers to all gases naturally occurring in nature, including gases formed by various natural processes in the atmosphere, water and rock circles (including oilfield gas, gas field gas, mudstone gas, coalbed gas, biogenic gas, etc.). The utility model provides a natural gas steady voltage pipeline high pressure alarm device is generally installed on the natural gas steady voltage pipeline, grant the patent of bulletin number CN208566205U, the name is "a natural gas steady voltage pipeline high pressure alarm device", including the pipeline body, natural gas alarm structure and flange, pass through flange joint between pipeline body and the natural gas alarm structure, natural gas alarm structure includes drum and first bracing piece, the one end and the drum inner wall vertical fixation of first bracing piece, the other end fixedly connected with arc backup pad, the top of arc backup pad is equipped with the dog, the fixed surface of drum is connected with the collection tank, be equipped with the U-shaped plate in the collection tank, the both ends of U-shaped plate all are connected with the fixed surface of drum, the lower fixed surface of U-shaped plate is connected with the elastic expansion link, the one end and the dog fixed connection of U-shaped plate are kept away from to the elastic expansion link. The high-pressure alarm device for the natural gas pressure stabilizing pipeline is convenient to operate, can timely find out pressure change of the pipeline, avoids potential danger, is comprehensive in pipeline detection, can collect natural gas, protects the environment from natural gas pollution, and avoids the leaked natural gas from damaging human health. However, when the natural gas pressure stabilizing pipeline high-pressure alarm device is installed, an installer passes through the through holes in the flanges through the bolts for connecting the two flanges, then sleeves the nuts on the bolts and tightens the nuts by using the tool, in order to prevent the bolts from rotating in the nut tightening process, the heads of the bolts are fixed by using the handheld tool, and the installation efficiency is low. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides a high-pressure alarm device for a natural gas pressure stabilizing pipeline. The technical scheme includes that the natural gas pressure stabilizing pipeline high-pressure alarm device comprises a natural gas alarm structure, two clamping sleeves are sleeved on the natural gas alarm structure, flange plates are fixed at two ends of the natural gas alarm structure, a plurality of slots for inserting heads of bolts are arranged on opposite side walls of the two clamping sleeves, a stop block is fixed at the top end of the two clamping sleeves, two lifting rods are arranged between the two flange plates, through holes for allowing the bottom ends of the lifting rods to pass are arranged at the top ends of the two stop blocks, springs are sleeved on the two lifting rods, clamping blocks are fixed at the bottom ends of the two lifting rods, and slots matched with the clamping blocks are arranged at the top ends of the two flange plates.
