Quick-open pressure vessel safety self-locking mechanism
Thread Content
The capacity regulations stipulate that quick-opening pressure vessels need to be equipped with a safety self-locking device. What kind of mechanism is this safety self-locking device? The newly purchased quick-opening blind plate of our unit is shown in the figure below. The manufacturer said that it is a quick-opening blind plate with a self-locking device. The exhaust plug in the picture can be opened to exhaust air and release the residual pressure. However, the capacity regulations require that the quick-opening door cannot be opened when there is residual pressure in the container. Does this exhaust method to release the residual pressure or detect the residual pressure conflict with the requirements of the capacity regulations?
Even if you call the safety interlock device, you will be confused. TSG21-2016 3.2.16 has requirements. Exhausting is possible, but as long as there is pressure inside, the door cannot be opened by force. It will never be opened without exhaust. Today's safety interlocking devices are generally controlled by computers, which makes them safer. Generally there is a limit switch, and the door cannot operate unless it is closed to the predetermined position. The equipment can generally be opened when the temperature is lower than 0.03MPa.
First, it is necessary to confirm whether the interlocking device of the quick-opening blind plate has the two functions that meet the requirements of TSG21-2016 3.2.16. Second, it is necessary to confirm whether the design unit has stipulated the technical requirements for the use of the interlocking device such as the environment, calibration cycle, and calibration methods.
