Abstract

The present invention relates to an explosion venting device with nozzles, which device comprises a cover body (1) with nozzles and a connecting rod (2) provided on the cover body, a unit (3) for guiding the sliding of the connecting rod and a frictional layer (4) provided on the inside of the connecting rod. The explosion venting device of the present invention is integrated with the nozzles, so that the structure of the whole device is simplified and is convenient to use and install.

Description

technical field [0001] The invention belongs to a safety device, in particular to an explosion venting device with a nozzle. Background technique [0002] Existing electric power, petroleum, chemical, textile, heating and other industries may all involve portable devices that, although small in structure, may cause explosions and deflagrations with excessive pressure build-up. In the process of explosion and deflagration, a strong recoil force will be generated on the device, which will hurt the operator, and the deflagration and explosion will produce fragments or the objects at the nozzle will be separated from the body and fly around, which may cause damage to surrounding people and property. accidental injury. For example, in a portable aerosol fire extinguishing device, when the powder column deflagrates, due to the small outlet nozzle, the hot aerosol gas will rapidly accumulate in the cylinder, and the pressure in the cylinder will increase rapidly, so the heat energ...
