Abstract

The invention discloses an automatic powder spraying explosion suppressor for coal mine fire protection, and relates to a fire protection explosion suppressor. A sheath is fixed at the lower end of a steel powder storage bottle and is fixedly butted with a connection flange in a sealing manner; a power supply connector is fixed on the sheath and is mounted on a gas pipeline through the connection flange and sealing rings; a nozzle body is arranged on a fastening flange; an anti-explosion device is arranged on the nozzle body; a flange disk is fixed at the lower end of the steel powder storage bottle; a filling valve is mounted on the rear side of the flange disk; a pressure switch is mounted on the front surface of the flange disk; a starter is fixed on the right side of the fastening flange; an electric detonator is mounted in a starter shell; a mandril with sealing rings is mounted at the front end and is fixedly pressed by a pressing nut; a transverse lever is arranged in an inner hole of the fastening flange. The automatic powder spraying explosion suppressor is simple in structure, safe and reliable, is high in starting speed and jetting speed and can meet the requirement on environment friendliness.

Description

technical field [0001] The invention relates to a fire-fighting equipment, in particular to an automatic powder spraying explosion suppressor for coal mine fire-fighting. Background technique [0002] In order to prevent the explosion of coal mine gas during pipeline transportation, it is necessary to install an automatic powder spraying explosion suppressor on the gas transportation pipeline. ≤150ms) implement powder spraying to suppress explosion. Existing explosion suppressors have relatively complex structures and relatively single functions, and the speed and sensitivity of starting and spraying are not ideal enough. Contents of the invention [0003] The object of the present invention is to provide an automatic powder spraying explosion suppressor for fire-fighting in coal mines. The explosion suppressor proposes a new structural form, valve opening mode, fire extinguishing agent driving mode and cylinder inner To solve the technical problem of the monitorability ...
