Carbon dioxide exploitation utensils composite pad ring type rupture disc device

The utility model discloses a carbon dioxide exploitation utensils composite pad ring type rupture disc device, include: go up backing ring, rupture disk and lower backing ring, rupture disk upper portion and lower part have last backing ring and time backing ring through the fastening of double sided glue knot respectively, last backing ring put processing respectively with lower backing ring central point and have circular backing ring through -hole and the circular backing ring through -hole down gone up, the diameter of last backing ring through -hole be less than the bore of releasing, the diameter of lower backing ring through -hole equal the bore of releasing. Carbon dioxide exploitation utensils composite pad ring type rupture disc device, when be heated gasification inflation of liquid carbon dioxide, the action of pressure control component realizes releasing fast high -pressure gas, the volume of releasing is sufficient, reaches the blasting effect, sealing performance is good. 本实用新型公开了种二氧化碳开采器用组合垫
