Abstract

The invention discloses an airtight test device for fire-fighting steel cylinders, and relates to the technical field of air-tightness tests for fire-fighting steel cylinders; in order to solve the problem of gas leakage at the joints at the top of the fire-fighting steel cylinders; it specifically includes a main body box, and the front outer wall of the main body box is opened with a The installation hole, and the inner wall around the installation hole is provided with the same tempered glass, the bottom inner wall of the main box is provided with a fixing seat, and a self-locking mechanism is arranged inside the fixing seat, and the outer walls of both sides of the main box are provided with chute, two The inner wall of the chute is slidably connected with L-shaped sliding rods, and the opposite ends of the two L-shaped sliding rods are provided with the same connecting plate, and the bottom of the connecting plate is provided with a clamping and fixing mechanism, and the front outer wall of the main box has a limiting slot. And the inner wall of the limiting groove is connected with the fixing frame through the sealing strip, and the front outer wall of the fixing frame is provided with a through hole. The invention effectively avoids the possible leakage problem at the top of the fire cylinder, and improves the effectiveness of experimental detection.

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 ...
