Abstract

PURPOSE: To obtain a release device with simple structure which can release the abnormal high pressure in a container by setting up an axis in which case a pressure receiving plate is fixed slidably and a pair of springs at the symmetrical position of an axial center so that they can open and colse the pressure receiving plate.
CONSTITUTION: The case 11 of a release device 4 has a partition plate 16 between the release tube 3 at one end and the flange 15 at the other end and excludes atmospheric air by a packing 17. A pressure receiving plate 19 is fixed in the partition plate of an axis 20 and its opposed end and a needle 21 at the tip of the axis. A pair of springs which are actuated in the direction wherein the pressure receiving plate closes at the symmetrical position of the axial center and in the direction wherein it opens after they passes through the dead spot is mounted between the case and the axis. This structure permits acqusition of a release device with simple structure whose pressure receiving plate opens and closes the device by means of the balance of the spring in the device and which discharges high pressure outside the device when abnormal high pressure is generated in a container 1
