Vessel fracturing safety device - comprises pressure vessel with corrugated walls in housing open to pressure chamber

摘要

The fracturing safety device is for fitting to a slide valve of a high pressure vessel so as to reduce the pressure of trapped fluid and prevent excess pressure due to heat expansion. The housing (1) has a chamber open to the pressure chamber (3), and in which a corrugated pressure vessel (2) is inserted. The vessel can be connected to a pressure indicator, and can be mounted outside the chamber to be relieved of load, and to which it is connected by a pipe.
