Abstract
The utility model discloses an air supply silencer of an airplane air source vehicle. The air supply silencer comprises a main body pipe and a safety valve, wherein the main body pipe is provided with an inner cavity and an outer cavity; and the inner cavity of the main body pipe is provided with a bypass flow air valve port and an exhaust port, and the outer cavity of the main body pipe is provided with a safety valve port and an air inlet port. The air supply silencer provided by the utility model has the beneficial effects that an high and low frequency erasure effect is realized through the mutation of a pipeline of the inner cavity and the change of flow area and the change that a large diameter is changed into a small diameter on the structure, and safety protection can be realized by an outer connecting safety valve.
Description
Technical field
The present invention relates to a kind of silencing apparatus, it is used in the air supply system that is arranged on the aircraft air source truck.
Background technique
The noise that the air supply system of present aircraft origin car produces for the aircraft air feed time, because its intensity is higher, energy is many, and to creating a great impression of human body and environment, the harm operator's is healthy.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of air feed baffler of aircraft air source truck.
The technological scheme that solves the problems of the technologies described above is: a kind of air feed baffler of aircraft air source truck, comprise main body tube and safety valve, and described main body tube is provided with inner chamber and exocoel; The inner chamber of described main body tube is provided with shunting air valve interface and exhaust port; The exocoel of described main body tube is provided with relief valve connection and suction port.
Described safety valve is arranged on the relief valve connection of described main body tube exocoel.
The invention has the beneficial effects as follows: by the sudden change of inner chamber pipeline and the change of circulation area; The large footpath variation of footpath in structure that diminish: realize the erasure effect of low-and high-frequency, realize the superpressure safety protection by external safety valve.
Description of drawings
Fig. 1 is the structural representation of the air feed baffler of aircraft air source truck.
Fig. 2 is the plan view of the air feed baffler of aircraft air source truck.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As depicted in figs. 1 and 2, a kind of air feed baffler of aircraft air source truck comprises main body tube 1 and safety valve 2, and described main body tube is provided with inner chamber 3 and exocoel 4; The inner chamber 3 of described main body tube 1 is provided with shunting air valve interface 5 and exhaust port 6; The exocoel 4 of described main body tube 1 is provided with relief valve connection 7 and intake interface 8.
the working principle of the air feed baffler of above-mentioned aircraft air source truck is: air-flow flows according to the direction of arrow shown in Figure 1, at first air-flow enters the exocoel of main body tube by the intake interface 8 of main body tube 1, to pass through safety valve 2 during air flow direction inner chamber 3, when stream pressure during less than safety valve 2 setting value, safety valve 2 cuts out, air-flow directly flows to inner chamber 3, when stream pressure during greater than safety valve 2 setting value, safety valve 2 is opened, air-flow is diverted in atmosphere by safety valve 2, thereby real superpressure safety protection, after air-flow flows into inner chamber 3, flow to respectively exhaust port 6 and shunting air valve interface 5.By the sudden change of inner chamber 3 pipelines and the change of circulation area; The large footpath variation of footpath in structure that diminish: the erasure effect that realizes low-and high-frequency.
Claims (2)
1. the air feed baffler of an aircraft air source truck, comprise main body tube and safety valve; It is characterized in that: described main body tube is provided with inner chamber and exocoel; The inner chamber of described main body tube is provided with shunting air valve interface and exhaust port; The exocoel of described main body tube is provided with relief valve connection and intake interface.
