Problems solved by technology

[0002] According to the "Civil Air Defense Engineering Protective Equipment Test and Quality Inspection Standard", the airtight performance test of the protective airtight door is required. The airtightness test can be carried out in the laboratory during the production process of the protective airtight door, and the protective airtight door at the installation site has There are two forms of single door and double door. When testing the airtightness of a single door, it is first necessary to build an overpressure chamber, that is, to build an airtight wall behind the airtight door. Since the door frame and door cannot be damaged during the inspection, the overpressure chamber must be filled with air. The channel is blocked, and it is difficult to carry out the air tightness test. In addition, it is very difficult to achieve the air leakage required by the test to be less than 0.001 cubic meters per hour in the construction of the on-site overpressure chamber, which requires considerable manpower and material resources. Therefore, a single door is generally Unable to conduct on-site air tightness test

Embodiment Construction

[0034] Now refer to Figure 6 to Figure 15 Describe the on-site airtightness test method embodiment of a kind of protective airtight door of the present invention, this test method is as follows:

[0035] S1. Preparation before the test:

[0036] S1.1. Remove the lock shafts of the upper lock 26 and the lower lock 21 of the protective airtight door 20, process two pieces of test lock shafts according to the shape of the lock shafts, and process the air hole 15 in the center of the test lock shafts. For the test lock shafts, see Figure 8 , the vent hole is used to protect the ventilation between the inside and the outside of the airtight door 20, and the orifice of the vent hole located on the outside is processed with a pipe thread, and the pipe thread is used to connect with the trachea joint of the sealing test equipment 24, and the test lock shaft After the processing is completed, two test lock shafts are respectively packed into the upper lock 26 and the lower lock 21 o...

Abstract

The invention belongs to the field of civil air defense engineering quality inspection, and specifically relates to an on-site airtightness test method of a protective airtight door, which solves the problem of inflating and pressure measurement in the field test by replacing a lock with a ventilation function, and measures the airtightness separately by sealing the protective airtight door The air leakage of the wall, and then measure the total air leakage of the sealing wall and the airtight door, and calculate the air leakage of the airtight door, which solves the problem of difficult construction of the overpressure chamber, and effectively improves the reliability and accuracy of the measurement.
