Civil air defense engineering protective equipment refers to the general term for reinforced concrete protective equipment, steel structure manual protective equipment, valves, electric control doors, anti electromagnetic pulse doors, subway and tunnel main line protective airtight doors, and other protective equipment used in civil air defense engineering to avoid and reduce air strike damage. To strengthen the construction and management of civil air defense facilities, ensure the quality of civil air defense equipment, and guarantee the quality and efficiency of civil air defense facility construction. Doing a good job in the quality inspection and management of civil air defense engineering protective equipment plays an important role in strengthening the quality supervision of civil air defense engineering protective equipment and enhancing the overall protective function of civil air defense engineering.

personThe quality inspection of engineering protection equipment can be divided into routine inspection and specialized performance inspection in terms of contenttwo categories.*ClassConventional testing is the inspection of the processing and installation quality of protective equipment, including external dimensions and fitting dimensions, performance, materials, and appearance quality;Category IISpecial performance testing includes: sealing performance testing for sealed protective equipment, ventilation performance testing for valve type protective equipment and sealed valves, wave attenuation performance testing for valve type wave attenuation systems, shielding performance testing for shielding type protective equipment, and resistance performance testing for resistance type protective equipmentwaitTesting instruments and equipment should be regularly maintained and serviced to ensure that they are always within their calibration validity period.

1.Conventional testing equipment

Measuring instruments and equipment for external dimensions and fitting dimensions: micrometer, vernier caliper, ruler, tape measure, feeler gauge, vernier caliper, flatness tester, perpendicularity tester, thread tester, coaxiality tester, etc. Use performance testing instruments and equipment: tension meter, timer.

Material and appearance quality testing instruments and equipment: rebound tester (measuring)ready-mixed concreteStrength), steel bar scanner (measuring the arrangement of steel bars and the thickness of the protective layer in commercial concrete), commercial concrete ultrasonic testing analyzer (measuring hidden dangers such as holes and joints in commercial concrete structures), steel plate thickness gauge, metal ultrasonic flaw detector (detecting welds), paint film thickness gauge and grid cutting tool (detecting paint thickness and adhesion).

The material (strength and physical and chemical tests) of metal materials can be entrusted to qualified specialized institutions for testing.

2. Sealed performance testing equipment

Instrument equipment for testing system: air compressor or safe and reliable gas source, pressure gauge, flow meter (assembly), micro pressure gauge, pressure gauge, temperature and humidity gauge.

Testing Platform: To install and debug a platform that meets the needs of vertical installation and testing of air leakage for protective equipment with a door hole size of 6 meters X 3.5 meters or less.

3.Ventilation performance testing equipment

Instrument equipment for testing system: micro pressure gauge, pressure gauge, temperature and humidity gauge.

Testing platform: It is a ventilation performance testing device that meets the needs of measuring the air volume and resistance of valves with equivalent diameters below 1000 millimeters.
