Background
The explosion container is equipment capable of restraining shock waves and fragments generated after explosion in the explosion container and protecting external people and objects from being damaged, and has wide application in the fields of scientific research, dangerous chemical transportation, explosion prevention and other public safety fields. The pressure of the shock wave after explosion is an important explosion parameter, has important significance for grasping the safety of the explosion container and needs to be measured. The pressure of the shock wave needs to be measured by an overpressure sensor, the front end test surface of the overpressure sensor needs to be installed at a designated position, and the rear end cable is connected with the acquisition equipment through a connector (generally a BNC connector). The sensor needs to be arranged inside a sealed explosion container, the collecting equipment is arranged outside the container, and the container needs to be kept sealed in the whole explosion process. The sealing problem is generally solved through switching, namely standard BNC connectors are respectively arranged on the inner side and the outer side of the container flange adapter plate, the inner side is connected with the sensor connector, and the outer side is connected with the collecting equipment. The method can meet the measurement requirement, but because the single BNC has larger size, a larger area is required to be reserved on the adapter plate with limited size under the condition of more test channels so as to install the BNC adapter, and the adapter plate is not favorable for bearing higher pressure, and stress concentration and leakage can be caused. In addition, the cost of the adapter plate is high, and the adapter plate needs to be reworked and manufactured when BNC channels are damaged after explosion, the number of the test channels does not meet the requirement or the size of the flange is changed. Based on this we propose a structure that allows the sensor cable to be passed directly out of the container without affecting the container seal.
