Optical analyzer having a holder for installation in a gas-carrying hollow space
An optical analyzer, in particular an optical gas analyzer, having a holder ( 10 ) for installing into a gas-carrying hollow space, wherein the holder ( 10 ) has a ball socket ( 20 ) and a ball segment ( 30 ) with a longitudinal axis (A), wherein the ball socket ( 20 ) has at least one first segment ( 21 ) and a second segment ( 22 ) and is designed such that it at least partly engages around the ball segment ( 30 ) in the direction of the longitudinal axis (A).
1. An optical analyzer comprising:
a holder ( 10 ) for installing the analyzer into a gas-carrying hollow space and withstanding pressures up to 20 bar, the holder ( 10 ) comprising:
a ball socket ( 20 ), having a first segment ( 21 ) and a second segment ( 22 ) and an inner surface; and
a ball segment ( 30 ) having a longitudinal axis (A) and a fastening ring ( 34 ),
wherein the ball segment ( 30 ) is inserted between the first and second segments ( 21 , 22 ), the inner surface directly contacting both sides of a largest diameter (D) of the ball segment ( 30 ) perpendicular to the longitudinal axis (A) to thereby fix the ball segment ( 30 ) along the longitudinal axis (A) in both directions when the first and second segments ( 21 , 22 ) are joined, and an inclination of the ball segment ( 30 ) relative to the ball socket ( 20 ) about the longitudinal axis (A) is fixed by means of at least two threaded bars ( 40 ), which are each positioned through a respective passage opening ( 36 ) in the fastening ring ( 34 );
wherein the ball segment ( 30 ) is fixedly connected to the optical analyzer;
wherein the ball socket ( 20 ) is fixedly connected to a wall of the gas-carrying hollow space; and
wherein at least one seal ( 50 ) is provided between the ball socket ( 20 ) and the ball segment ( 30 ).
2. An optical analyzer in accordance with claim 1 , wherein the threaded bars ( 40 ) are fixedly connected to the ball socket ( 20 ) at one end ( 40 a ) and are directly or indirectly fixable to the ball segment ( 30 ) at the other end of the threaded bars ( 40 b ) with the aid of bolt nuts ( 44 ).
3. An optical analyzer in accordance with claim 1 , wherein a spring element ( 12 ) is arranged between the ball socket ( 20 ) and the ball segment ( 30 ).
4. An optical analyzer in accordance with claim 2 , wherein a helical spring ( 42 ) or a plate spring is arranged around at least one of the threaded bars ( 40 ) between the ball socket ( 20 ) and the ball segment ( 30 ).
5. An optical analyzer in accordance with claim 3 , wherein a helical spring ( 42 ) or a plate spring is arranged around at least one of the threaded bars ( 40 ) between the ball socket ( 20 ) and the ball segment ( 30 ).
6. An optical analyzer in accordance with claim 1 , wherein the inclination is adjustable within two degrees about the longitudinal axis (A).
7. An optical analyzer comprising:
a holder ( 10 ) for installing the analyzer into a gas-carrying hollow space and withstanding pressures up to 20 bar, the holder ( 10 ) comprising:
a ball socket ( 20 ), having a first segment ( 21 ) and a second segment ( 22 ) and an inner surface;
a ball segment ( 30 ) having a longitudinal axis (A) and a fastening ring ( 34 ); and
a cylindrical section molded at the ball segment, extending from the second segment ( 22 ) along the longitudinal axis (A) to a free end, the free end attached to the fastening ring ( 34 ) of the ball segment ( 30 ) such that the fastening ring ( 34 ) faces the ball segment ( 30 ),
wherein the ball segment ( 30 ) is inserted between the first and second segments ( 21 , 22 ), the inner surface directly contacting both sides of a largest diameter (D) of the ball segment ( 30 ) perpendicular to the longitudinal axis (A) to thereby fix the ball segment ( 30 ) along the longitudinal axis (A) in both directions when the first and second segments ( 21 , 22 ) are joined, and an inclination of the ball segment ( 30 ) relative to the ball socket ( 20 ) about the longitudinal axis (A) is fixed by means of at least two threaded bars ( 40 ) which are each positioned through a respective passage opening ( 36 ) in the fastening ring ( 34 );
wherein the ball segment ( 30 ) is fixedly connected to the optical analyzer;
wherein the ball socket ( 20 ) is fixedly connected to a wall of the gas-carrying hollow space; and
wherein at least one seal ( 50 ) is provided between the ball socket ( 20 ) and the ball segment ( 30 ).
