Abstract
The utility model discloses a self sealss post chamber. The self-sealing column cavity comprises an external column cavity and an internal column cavity; the plug-in connection position of the external column cavity is provided with a concave spigot, the plug-in connection position of the internal column cavity is provided with a convex spigot, a sealing knife edge is arranged on the convex spigot of the internal column cavity, and the concave spigot of the external column cavity is in clearance fit with the convex spigot of the internal column cavity. During assembly, the male spigot of the inner connecting column cavity is inserted into the female spigot of the outer connecting column cavity, the female spigot of the outer connecting column cavity generates acting force on the sealing knife edge, the tip of the sealing knife edge generates plastic deformation and is extruded into the female spigot of the outer connecting column cavity, and under the action of pressure and friction force, the sealing knife edge is tightly matched with the female spigot of the outer connecting column cavity, so that the outer connecting column cavity and the inner connecting column cavity are firmly connected together, and a sealing effect is achieved. The utility model discloses a self sealss post chamber is applicable to the post chamber target of preparation inertial confinement fusion, has avoided the viscose to pollute the post chamber. The utility model discloses a self sealss post chamber application method has convenient operation, simple structure, the reliable advantage of butt joint.
Description
Technical Field
The utility model belongs to inertial confinement fusion field, concretely relates to self sealss post chamber.
Background
In the field of inertial confinement fusion targets, the conventional column cavity is bonded together, so that the quality of the column cavity target is affected due to the fact that glue cannot penetrate into the inner wall of the column cavity, and therefore the design of the column cavity needs to be improved so as to improve the quality of the target.
Disclosure of Invention
The utility model aims to solve the technical problem that a self sealss post chamber is provided, the utility model aims to solve another technical problem that a self sealss post chamber's application method is provided.
The utility model discloses a self sealss post chamber, its characteristics are: the self-sealing column cavity comprises an external column cavity and an internal column cavity; a concave spigot is arranged at the splicing position of the external column cavity, and the diameter of the concave spigot is D1; a convex spigot is arranged at the splicing position of the inner connecting column cavity, the diameter of the convex spigot is D2, a sealing knife edge is arranged on the convex spigot of the inner connecting column cavity, and the diameter of the tip end of the sealing knife edge is D; d > D1;
the concave spigot of the external column cavity is in clearance fit with the convex spigot of the internal column cavity, and D1 is more than D2;
the external column cavity and the internal column cavity are coaxially arranged.
The material of the external connection column cavity and the internal connection column cavity is gold.
The surface roughness of the inner surfaces of the external column cavity and the internal column cavity is Ra0.1.
The tolerance of the inner diameters of the external column cavity and the internal column cavity is +/-5 microns.
The utility model discloses a with the male end of internal column chamber insert the female end in external column chamber during self sealss column chamber assembly, the female end in external column chamber produces the effort to sealed edge of a knife, makes the most advanced plastic deformation that produces of sealed edge of a knife crowd into in the female end in external column chamber, under the effect of pressure and frictional force, the sealed edge of a knife closely cooperates with the female end in external column chamber, makes external column chamber and the firm connection in internal column chamber be in the same place to play sealed effect.
The utility model discloses a self sealss post chamber is applicable to the post chamber target of preparation inertial confinement fusion, can make the butt joint terminal surface in external post chamber and internal connection post chamber need not bond and inseparable butt joint together, has avoided the viscose to pollute the post chamber. The utility model discloses a self sealss post chamber application method has convenient operation, simple structure, the reliable advantage of butt joint.
