Summary of the invention
The objective of the invention is to propose a kind of defense equipment detection platform and air-tightness detection method thereof, it is characterized in that, described defense equipment detection platform adopts moveable structure, and this platform is divided into upper and lower two parts, fixed thermometer, flowmeter on upper panel; Tensimeter and tilting micromanometer; This platform bottom is storeroom; Operation valve and inflator be placed in storeroom or be arranged on platform outer near; Wherein inflator, operation valve, tensimeter and flowmeter series connection, then the measuring superpressure of defense equipment chamber air intake opening is received in the flowmeter outlet, and tilting micromanometer is received gas outlet, defense equipment measuring superpressure chamber.
Described defense equipment air-tightness detection method, adopt the level pressure method to detect air leakage, specifically comprises:
1) contact structures that are to protect doorframe and protective door of the air-tightness of decision defense equipment, therefore protect doorframe and the good material of protective door application impermeability is made;
2) will protect on doorframe and be installed on measuring superpressure chamber, form plenum space; Set out gas port and air intake opening on the flat board of superpressure chamber, seal with sealing adaptor at ordinary times;
While 3) measuring, the measuring superpressure of defense equipment chamber air intake opening is received in the flowmeter outlet, and tilting micromanometer is received gas outlet, defense equipment measuring superpressure chamber;
4) temperature is controlled at 10 ℃-30 ℃;
5) impermeability detects
A, check that temperature is whether between 10 ℃-30 ℃; Whether defense equipment protection doorframe and protective door shut; Whether gas circuit connects correct; Whether each junction leaks gas, whether leveling of tilting micromanometer, and whether the range of flowmeter the coincidence measurement scope;
B, toward adding concentration in microbarograph, be the alcohol more than 95%, adjust 0 point of microbarograph;
C, open inflator toward the indoor inflation of superpressure, inner gas pressure is 0.4MPa, the size of adjust flux meter, and the stable reading that makes tilting micromanometer during at 50Pa or at 100Pa, requires to keep 5 minutes, then reads the reading of flowmeter, and this reading is air leakage;
6) if need to determine air-leak section, adopt traditional painting suds, bubbling place, be exactly air-leak section.
The invention has the beneficial effects as follows it is that the packaged type detection platform moves flexibly, can detect the impermeability of people's air defense safeguard Anywhere, easy to operate, and reach the quantitative check requirement by tilting micromanometer.The impermeability that detection platform also is applicable to ventilation equipment in civil air defense constructions and installations detects use.
The accompanying drawing explanation
Fig. 1 is packaged type detection platform structural representation.
Embodiment
The present invention proposes a kind of defense equipment detection platform and air-tightness detection method thereof.Below in conjunction with accompanying drawing, be described as follows:
Figure 1 shows that packaged type detection platform structural representation.In figure, defense equipment detection platform 9 adopts moveable structure, and this platform is divided into upper and lower two parts, fixed thermometer 7, flowmeter 4, tensimeter 3 and tilting micromanometer 6 on upper panel; This platform bottom is storeroom 8; Operation valve 2 and inflator 1 be placed in storeroom 8 or be arranged on defense equipment detection platform 9 outer near; Wherein inflator 1, operation valve 2, tensimeter 3 and flowmeter 4 series connection, then the measuring superpressure of defense equipment 5 chamber air intake opening is received in flowmeter 4 outlets, and tilting micromanometer 6 is received gas outlet, defense equipment 5 measuring superpressure chamber.
Described defense equipment air-tightness detection method, adopt the level pressure method to detect air leakage, specifically comprises:
1) contact structures that are to protect doorframe and protective door of the air-tightness of decision defense equipment, therefore protect doorframe and the good material of protective door application impermeability is made;
2) doorframe of measured defense equipment is fixed with fastening bolt and pressing plate and superpressure chamber, between doorframe and superpressure chamber, with the glass cement sealing, realized that seam is airtight, form plenum space, the valve place of air intake opening and pressure tap adds sealing gasket, prevents gas leakage;
While 3) measuring, the measuring superpressure of defense equipment 5 chamber air intake opening is received in flowmeter 4 outlets, and tilting micromanometer 6 is received gas outlet, defense equipment 5 measuring superpressure chamber
4) temperature is controlled at 10 ℃-30 ℃;
5) impermeability detects
A, check that temperature is whether between 10 ℃-30 ℃; Whether defense equipment protection doorframe and protective door shut; Whether gas circuit connects correct; Whether each junction leaks gas, whether leveling of tilting micromanometer, and whether the range of flowmeter the coincidence measurement scope;
