Non-glass device for connecting laser gyroscope with exhaust station

Abstract

A non-glass device for connecting a laser gyroscope with an exhaust station is characterized in that a first corrugated pipe and the vacuum exhaust table are installed in a butt joint mode, the other end of the first corrugated pipe is connected to a three-way connector, the other end of the three-way connector is connected with a second corrugated pipe, a clamping sleeve connector of the second corrugated pipe is connected with the laser gyroscope, and the laser gyroscope is electrically connected with a high-voltage power source. The third port of the three-way connector is connected with a storage tank through a sealing connector, the storage tank is made of a non-glass material and is a hollow flat-bottom round cylinder with an opening in the upper end, and a getter is arranged on the flat bottom of the inner cavity of the storage tank. Flexible connection and sealing butt joint are achieved through the corrugated pipes, the sealing connector and the clamping sleeve connector respectively, so that the connection and disassembly efficiency of all parts between the laser gyroscope and the vacuum exhaust station is remarkably improved compared with glass sintering, meanwhile, potential safety hazards of a glass structure are avoided, fireless operation of the laser gyroscope is achieved, and the laser gyroscope is safe, convenient to use, and good in air tightness. In addition, thermal deformation interference is effectively reduced through a flow dividing device, the measurement precision of the laser gyroscope is improved, and the device has high practical value.

Description

Technical field

[0001] The present invention belongs to the technical field of inertial navigation equipment manufacturing, and more particularly to a non-glass device for laser gyro connection discharge space.Background technique

[0002] The laser gyro is a sensor for measuring the angular rate of the moving object. It is one of the types of sensors commonly used in modern inertia navigation techniques. The general form is a ring-shaped helium laser resonant cavity, and the commonly used laser resonant cavity has quadrilateral and triangles. Similarly to conventional helium lasers, the laser gyrograph is filled with a he-neon gas in the laser gyro, referred to as a working material, ensuring that the purity of the working substance is the core of maintaining the life of the laser gyro. Since there is a larger pressure difference in the laser gyrch cavity (about 0.9 atmospheres), there is a difficult challenge to the laser gyro manufacturing process within the use and storage period of a...
