Abstract

An automatic powder-spraying explosion suppressor for fire-fighting in a coal mine relates to a fire-fighting explosion suppressor. A sheath is fixed at the lower end of a powder storage steel cylinder, and the sheath and a connecting flange are sealed and fixed, and a power connector is fixed on the sheath. The connecting flange and sealing ring are installed on the gas pipeline, the spout body is set on the fastening flange, the spout body is equipped with an explosion-proof device, and the flange plate is fixed at the lower end of the powder storage cylinder; the filling valve and pressure switch are installed on the rear side of the flange plate Installed on the front of the flange, the starter is fixed on the right side of the fastening flange; the electric squib is installed in the starter housing, and the front end is equipped with a push rod with a sealing ring, which is fixed and compressed by a compression nut; fastening method A horizontal lever is set in the blue inner hole. The powder spraying explosion suppressor has the advantages of simple structure, safety and reliability, fast starting and spraying speed, and conforms to environmental protection requirements.

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 ...
