PLANT FOR ANALYSIS OF EXPLOSION-PROOF MEMBRANES Russian patent published in 2014 - IPC F16K17/16 G01N3/313 

FIELD: machine building.

SUBSTANCE: proposed plant comprises explosion vessel. Charge of combustible mix is placed inside said vessel. Membrane fastening assembly is fitted in explosion vessel seat parallel about its axis. Pressure mechanical indicator with indicator motor switch-on selector is arranged inside vessel end section closed by protective shield, parallel with said membrane fastener. Explosion chamber is arranged coaxially and opposite the vessel end part closed by protective shield. Said chamber has unions for venting said vessel after experiment. Explosion chamber end section accommodates ignition plug with switch-on push-button arranged coaxially with said chamber. Combustible fluid filling union with the plug is secured at vessel wall, above ignition plug terminals. Said venting unions are equipped with vents to inhibit blow-out of combustible mix blast products. The following elements are involved in tests: pressure indicator, ignition plug, combustible fluid filling union, venting unions that feature breaking point at least two times higher than that of tested membrane.

EFFECT: higher efficiency of protection.
