Title:
HIGH PRESSURE SILENCING EXHAUST APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/104963
Kind Code:
A1
Abstract:
A high pressure silencing exhaust apparatus comprising a second silencing cavity; the second silencing cavity comprises a housing and a throttle core within the housing and coaxial with same; an inner wall of the housing is provided with an inner threading, an outer wall of the throttle core is provided with an outer threading that matches with the inner threading of the housing, a gas flow channel is formed between the inner threading of the housing and the outer threading of the throttle core, and a gas flow enters from a gas inlet end of the housing and, after passing the throttle core, is discharged outside of the housing. The high pressure silencing exhaust apparatus of the present application implements partitioned pressure reduction and noise reduction by means matching between the inner and outer threadings of the housing and the throttle core, a threading structure can achieve a greater gas flow contact area at a same size, thereby having a compact apparatus structure while ensuring pressure reduction and noise reduction, and also the gas flow flows along a helical surface, and consequently flow is smooth and steady, and good stability is achieved.
