The security door is responsible for the sealing performance of engineering, three-proofing ventilation conversion and the protection of a war personnel matrix, the security door is a product produced by a fixed-point manufacturer at present, although the security door is processed according to the requirements of design drawings, gaps are formed between the door body and a door frame due to process differences and processing errors. At this time, the product (security door) needs to be checked in a sampling mode. National civil defense industry standards RFJ01-2002 and RFJ04-2009 provide detection requirements for performances of a closed door and a security door, and determine maximum allowable air leakage of various specifications and models and a test method. The experimental method for the gas tightness performance generally comprises a flow method and a pressure drop method, wherein gas with certain pressure is filled in a sealing chamber, and the pressure drop rate is detected after the sealing chamber is maintained for 24 hours approximately to judge whether the sealing chamber leaks gas or not.

In the detection mode, a simulation wall body (which can be of a concrete structure or a steel bar plate structure) is arranged in a factory, a product to be detected is installed on the simulation wall body, then gas is injected into a security door to pressurize, and whether gas leaks between the security door and the simulation wall body or not is detected. At present, products needing to be tested are all transported to a factory, the logistics cost and the storage cost are extremely high, and the detection period is also prolonged; if the gate of a certain underground garage is 8m long and 2m high, the conventional factory can not detect even.
