Abstract

The invention discloses an airtightness test device for a fire-fighting steel cylinder, and relates to the technical field of airtightness tests for fire-fighting steel cylinders. The problem of gas leakage at the top end joint of the fire-fighting steel cylinder is solved. Specifically, the device comprises a main body box, a mounting hole is formed in the outer wall of the front surface of the main body box; the same tempered glass is arranged on the inner walls of the periphery of the mounting hole; a fixed seat is arranged on the bottom inner wall of the main body box; a self-locking mechanism is arranged in the fixed seat; sliding grooves are formed in the outer walls of the two sides of the main body box; L-shaped sliding rods are slidably connected with the inner walls of the two sliding grooves, the same connecting plate is arranged at the opposite ends of the two L-shaped sliding rods, a clamping fixing mechanism is arranged at the bottom of the connecting plate, a limiting groove is formed in the outer wall of the front face of the main body box, a fixing frame is connected with the inner wall of the limiting groove through a sealing strip, and a through hole is formed inthe outer wall of the front face of the fixing frame. The leakage problem possibly occurring at the top end of the fire-fighting steel cylinder is effectively avoided, and the effectiveness of experimental detection is improved.

Description

technical field [0001] The invention relates to the technical field of airtightness test of fire-fighting steel cylinders, in particular to an airtightness test device for fire-fighting steel cylinders. Background technique [0002] A fire cylinder is a steel bottle-shaped container that stores gas for fire extinguishing. In the production field of fire-fighting steel cylinders, after the production of fire-fighting steel cylinders is completed, a sealing test is required to test their tightness. The traditional tightness test is to judge whether the fire cylinder is qualified by injecting high-pressure gas into the fire cylinder and observing the change of the pressure of the high pressure gas. [0003] After retrieval, the Chinese patent application number is CN201920787861.7, which discloses a steel cylinder airtightness detection device, including a water tank, the center of the bottom of the inner cavity of the water tank is fixed with a load-bearing abutment, and the ...
