Abstract

The invention discloses an ice fog spraying device with an anti-freezing function, and belongs to the technical field of helicopter combined tests. The device comprises an air source system, a water supply system, a nozzle and a purging pipeline; the air source system includes an air source, an air supply adjusting valve and an air supply pipeline; the water source system includes a water source, a water supply adjusting valve and a water supply pipeline; the air source and the air supply adjusting valve are connected with the nozzle through the air supply pipeline; the water source and the water supply adjusting valve are connected with the nozzle through the water supply pipeline; one end of the purging pipeline is connected to the back end of the air supply adjusting valve, and the other end is connected to the back end of the water supply adjusting valve; the purging pipeline is provided with a manual purging stop valve and a one-way stop valve from an intake end in sequence; a redundant water discharge pipeline is arranged in the lowest place of the water supply pipeline, and is positioned at the back end of the water supply adjusting valve; and a redundant water discharge stop valve is arranged on the redundant water discharge pipeline. The device effectively removes redundant water in the water supply pipeline through simple modification, and reliably realizes anti-freezing of outdoor water supply pipeline.

Description

technical field [0001] The invention belongs to the technical field of helicopter comprehensive tests, and in particular relates to an ice mist spraying device with an antifreeze function. Background technique [0002] The purpose of building the helicopter ice fog spraying facility is to carry out the anti-icing test of the helicopter rotor. The air source system 1 and the water source system 2 are used to provide air and water with a certain temperature and pressure respectively, which are transported to the nozzle through the pipeline and sprayed under low temperature conditions. To simulate the real cloud environment. The ice fog spray test is an important test method to evaluate the effectiveness of the full-scale rotor anti-icing system and verify the anti-icing ability of the helicopter in the hovering state. [0003] A low temperature environment is a necessary condition for the formation of ice fog. In order to form a low temperature environment, artificial low te...
