Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Automobile air outlet impermeability monitor station is used to detect the specialized equipment of the air leakage of various automobile air outlets under in off position, monitor station comprises housing 100, pressure regulation unit, pressure definite value unit 4, flowmeter 6, microbarograph 1, and pressure regulation unit, 4 yuan of pressure fixed value lists, flowmeter 6, microbarograph 1 all are located in the housing 100.
See illustrated in figures 1 and 2ly, housing 100 integral body are sales counter shape, are convenient to people's operation, and housing 100 has air intake opening, give vent to anger and detect mouthful 2, first air storage chamber 51 and second air storage chamber, 52, the second air storage chambers 52 and detect mouth 2 and communicate with giving vent to anger by gas piping.
Pressure definite value unit 4 is used for stable gas pressure within the specific limits, and the outlet side communicates with first air storage chamber 51, and pressure definite value unit 4 is a valuator, and valuator is a kind of high-precision reduction valve, is mainly used in the pressure definite value.Generally, the fluctuation of valuator output pressure is not more than 1% of maximum output pressure, is usually used in the occasion that needs are supplied with accurate bleed pressure and signal pressure, as aerodynamic experiment equipment, pneumatic aut.eq. etc., sale is arranged on the market.
The air pressure that the pressure regulation unit will directly obtain from the source of the gas generator is adjusted, inlet end communicates with the air intake opening of housing 100, the outlet side communicates with the inlet end of pressure definite value unit 4, the pressure regulation unit comprises one-level pressure regulator valve 31 and secondary pressure regulator valve 32 compositions, connects with gas piping between one-level pressure regulator valve 31 and the secondary pressure regulator valve 32.Air pressure is difficult to carry out disposable air pressure adjusting and just can reaches in the needed air pressure range, so generally adopt repeatedly pressure regulation.
