Gas flow regulating device for icing-freezing rain test system

Abstract

The invention provides a gas flow regulating device for an icing-freezing rain test system; the device comprises a one-to-more gas supply communicator, a more-in-one gas supply communicator, a plurality of gas supply branch pipes and a plurality of gas supply branch switches; the one-to-more gas supply communicator is connected to a gas inlet of a gas supply pipe of the icing-freezing rain test system; the more-in-one gas supply communicator is connected to a gas outlet of the gas supply pipe of the icing-freezing rain test system; the gas supply branch pipes are parallelly connected between the one-to-more gas supply communicator and the more-in-one gas supply communicator; each gas supply branch switch is arranged on each gas supply branch pipe and is respectively used for controlling the on / off of each gas supply branch pipe, wherein the gas which is led in from the gas inlet of the gas supply pipe is shunted into the gas supply branch pipes through the one-to-more gas supply communicator; the gas in the gas supply branch pipes is collected into the more-in-one gas supply communicator and then is led to a plurality of spray nozzles of the icing-freezing rain test system through the gas outlet of the gas supply pipe; the gas is mixed with the sprayed water which is supplied to the spray nozzles, so that the water sprayed by the spray nozzles is atomized, and a tested sample is sprayed.

Description

technical field [0001] The invention belongs to the field of freezing rain environmental tests and relates to an air supply flow regulating device for a freezing rain test system. Background technique [0002] Freezing rain is also called rime. Freezing rain freezes on objects with a temperature below zero and forms ice. After freezing, it can break power lines, cause power supply and communication interruptions, and severe freezing rain can even collapse houses, break trees, freeze crops and vegetable. In addition, the damage caused by freezing rain to transportation is also very serious. When the aircraft flies in the cloud layer with supercooled water droplets, the wings and propellers of the aircraft will accumulate ice, which will affect the aerodynamic performance of the aircraft and cause accidents. Generally, for products exposed to icing / freezing rain environments, icing / freezing rain may cause corresponding physical and chemical effects on the product, affect prod...

In addition, the damage caused by freezing rain to transportation is also very serious. When an aircraft flies in the cloud layer with supercooled water droplets, the wings and propellers of the aircraft will accumulate ice, which will affect the aerodynamic performance of the aircraft and cause accidents.

Generally, for products exposed to icing / freezing rain environments, icing / freezing rain may cause corresponding physical and chemical effects on the product, affect product reliability and performance, and even cause product failure or damage
