DEVICE FOR CONNECTING AIR-TIGHT TEST VEHICLE BODY AND AIR-TIGHT TEST BENCH CASE

摘要

A device for connecting an air-tight test vehicle body and an air-tight test bench case. The device comprises: a transition body (2), the transition body (2) being channel-shaped and a middle plate (9) being arranged in the transition body (2), and a small sealing door (5) being arranged on the middle plate (9); a vehicle body connecting flange (3), the vehicle body connecting flange (3) being arranged at an end of the transition body (2), for connecting to an end part of the air-tight test vehicle body; a case connecting flange (1), the case connecting flange (1) being arranged at the other end of the transition body (2), for connecting to a large door of the air-tight test bench case; an evacuation port connecting flange (4), the evacuation port connecting flange (4) being arranged in the middle of the transition body (2), for connecting to an evacuation port of the air-tight test bed; and an inflation port connecting flange (6), the inflation port connecting flange (6) being arranged in the middle of the transition body (2), for connecting to an inflation port of the air-tight test bed. The device for connecting the air-tight test vehicle body and the air-tight test bench case achieves simultaneously loading from the inside and outside of the air-tight test vehicle body. Furthermore, a check can only be performed by entering the inside of the air-tight test vehicle body through the small sealing door in the transition body, when loading from the outside thereof.
