Embodiment Construction
[0025] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0026] A gas flowmeter housing sealing pressure test device, composed of a base 14, an annular support 5, a fixture 3 and two pressing bowls 9,16. The annular support is vertically fixed on the upper surface of the base by the fixed table 13, and the radial air inlet 19 is formed on the annular support, and the radial air inlet is connected with the workpiece (i.e. the gas flowmeter two halves of the housing 7, 17) The internal spaces are connected. An air inlet pipe 4 is installed on the radial air inlet hole, and a pressure gauge 1 is installed on the air inlet pipe, so that the pressure state inside the two half shells can be observed conveniently. Both sides of the annular support are formed with mounting rings 18 that can be axially cl...
