Abstract

The invention relates to a vacuum flux test device of air pipe head. The vacuum flux test device of air pipe head mainly solves the technical problems that the existing test method is low in measurement precision and affects the quality of the product. The vacuum flux test device of air pipe head comprises a motor, a converter, a draught fan, a measuring pipeline, a rectifier, a pilot tube, a first pressure transmitter, a first display, an air pressure sensor, a second pressure transmitter and a second display; the motor is connected with the draught fan; the converter is connected with the motor; the draught fan is connected with the measuring pipeline; the pilot tube and the air pressure sensor are installed on the measuring pipeline; the first pressure transmitter is connected with the pilot tube; the first display is connected with the first pressure transmitter; the second pressure transmitter is connected with the air pressure sensor; the second display is connected with the second pressure transmitter. The test device employs a special and unique structure, is able to reasonably, reliably and effectively test the flux of the sample piece; the equipment is advanced, the test result is in high precision; and the test device is also applicable to sample pieces of different calibers.

Description

technical field [0001] The invention relates to a test device for marine fittings, in particular to a vacuum flow test device for an air pipe head. Background technique [0002] The air pipe head is mainly used for cabin ventilation. Through inhalation and breathing, the air pressure in the tank is close to the atmospheric pressure, so that the pressure is kept within the design pressure of the tank, and it can also prevent seawater and rainwater from entering the tank. At present, there is no reliable and effective method for testing the vacuum flow rate of the air pipe head, which leads to a decrease in the accuracy of the vacuum flow test structure of the air pipe head, and it cannot be applied to vacuum pipe heads of different calibers. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the background technology, the present invention provides a reliable, effective and highly accurate vacuum flow test device for air pipe heads....
