Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] see first figure 2 As shown, the distance from the vacuum leak detection device of a laser gyro of the present invention to the laser gyro 1 is the vacuum exhaust unit 11, the leak detector 10, the exhaust valve 9, the three-way pipe 7, and the laser gyro 1. The flange 4 where the intake pipe and the narrow tube 3 are connected together, the copper tube 2 welded on the laser gyro 1 , and the laser gyro 1 .
[0027] refer to figure 2 Shown, the inflation device of a kind of laser gyroscope of the present invention mainly is provided with the helium gas bottle 16 of helium, the second flowmeter 17 of monitoring helium gas flow, provides the neon gas bottle 15 of neon gas, the first flowmeter of control neon gas flow rate. A flow meter 14, a gas mixing chamber 12 for mixing helium and neon, a second vacuum gauge 19 for monitor...
