Abstract

The invention relates to key parts in detection equipment, in particular to a high-reliability security check ceramic X-ray tube. The high-reliability security check ceramic X-ray tube comprises an anode assembly and a cathode assembly. An anode head in the anode assembly and a focusing disc in the cathode assembly are oppositely arranged. The high-reliability security check ceramic X-ray tube is characterized in that the anode assembly and the cathode assembly are assembled into a whole in a butt joint mode through a ceramic shell, the anode head and the focusing disc are arranged in the ceramic shell, the anode assembly is provided with a ray output window located outside the ceramic shell, the anode head is of a conical head structure, the focusing disc is provided with a small circular cavity and a large circular cavity and is of a cap structure, the large circular cavity is located at the outer end and is opposite to the anode head, the inner diameter of the large circular cavity is larger than the largest outer diameter of the anode head, and a water cooling sleeve is additionally installed at the tail end of the anode head. The high-reliability security check ceramic X-ray tube solves the problem that an existing security check tube is poor in reliability and short in service life, and is mainly used for various security check devices.

Description

technical field [0001] The invention relates to key components in safety inspection equipment, in particular to a high-reliability safety inspection ceramic X-ray tube. Background technique [0002] The security inspection tube is one of the core parts of the security inspection equipment. It is mainly composed of an anode assembly 4 and a cathode assembly 1 connected through a glass shell 3. See figure 1 The problem existing in the existing security inspection tube is: the glass shell 3 is easily broken and damaged; 2. wherein the anode head 6 in the anode assembly is a cylindrical structure, and the outer diameter of the anode head is nearly the same as the outer diameter of the focusing disk 5 of the cathode assembly. (and larger than the inner diameter of the focusing disk), this structure makes the electric field distribution unreasonable, and the electrons emitted by the cathode are easy to hit the shell, which seriously affects the service life of the product. The ser...
