Abstract

The invention relates to a safety valve for a fireproof and explosion-proof pipeline, comprising a shell, a ventilation cylinder, a rocking plate and a transmission and control mechanism; the ventilation cylinder consists a taper cylinder, a movable cylinder and a straight cylinder which are movably connected with each other; the shell is internally provided with a rocking plate shaft and the rocking plate; the rocking plate can be rotated around the rocking plate shaft. The invention has the advantages of compact structure, reasonable design, easy processing and low cost. The invention is suitable for the dust and fibre transmission pipeline system of flax textile industry and similar industries, which prevents the fire source from entering a dust and fibre collector which is flammable and explosive and prevents fire and explosive accidents.

Description

technical field [0001] The invention relates to a safety valve, in particular to a fireproof and explosion-proof pipeline safety valve used in flax and similar industries. Background technique [0002] At present, the dust removal pipeline in the linen textile industry is a pneumatic conveying system, and the dust and fiber materials generated in the pre-spinning process must be transported to the collector through the dust removal pipeline. Due to the existence of fibers, the inner wall of the dust removal pipe is required to be smooth and free of burrs, so as to prevent the fibers from being hooked and entangled, affecting the passage of air flow, and even blocking the pipe. Existing fire dampers used in the air-conditioning and ventilation pipeline systems of buildings such as hotels, shopping malls, and hospitals have structural forms such as rocker type, louver type, and butterfly type. When the cavity is not smooth, hooking and entanglement will occur on the rough par...
