The invention discloses a device for quickly opening an ultra-large cross section channel. The device for quickly opening the ultra-large cross section channel comprises a connecting supporting frame, an extension section, safety doors, a flow guide plate, blasting doors and a door frame structure; the extension section is positioned on the connecting supporting frame; the interior of the extension section is of a cavity structure and forms a flow guide channel; the safety doors and the flow guide plate are respectively positioned at the front end and the rear end of the flow guide channel, wherein the safety doors are positioned at the front end of the extension section and is arranged on the connecting supporting frame through a flow guide frame; the flow guide plate is positioned in the central line of the flow guide channel; the door frame structure is of a cone structure and is positioned between the extension section and the flow guide plate; the flow guide channel can be connected or disconnected through the opening and closing between the blasting door and the door frame structure. The device disclosed by the invention is simple in structure, convenient to operate, safe, reliable and high in sealing performance; the functions of connecting or disconnecting air flow between the two ends of the device can be realized.
Description
technical field [0001] The present invention relates to the technical field of equipment in the field of blasting tests, in particular, to a device for quickly opening a channel with a super-large cross-section. Background technique [0002] In the field of aviation, in the process of testing or testing some special parts, it is necessary to establish corresponding test devices. The test devices mainly include test chambers, diffusers and vacuum tanks. The diffuser is located behind the test chamber and is the entire The tail of the test device platform is directly connected to the vacuum tank. The main function of the diffuser is to restore the kinetic energy of the airflow to pressure energy, thereby reducing the energy loss of the airflow at the rear end of the diffuser. The main function of the test chamber is for the operator to conduct blasting tests on special parts in the test chamber. This requires that the test chamber and the vacuum tank be air-isolated before t...
