A kind of oblique ground quartz ampoule structure
Technical field:
This utility model relates to quartz ampoule technical field of structures, particularly to a kind of oblique ground quartz ampoule structure.
Background technology:
In existing technique, general employing quartz cap sealed silica envelope, the internal diameter of quartz pipe cap of the prior art and the external diameter of quartz ampoule are in the same size, together with the sleeve mutual with quartz ampoule of quartz pipe cap, realize sealing of quartz ampoule and fixing of quartz pipe cap, the dismounting inconvenience of this connected mode, and sealing is poor, is easy to flow backwards from junction, overflow in quartz ampoule during fluid injection.
Utility model content:
This utility model provides a kind of oblique ground quartz ampoule structure, solves dismounting inconvenience in prior art, the problem of sealing difference.
Technology solution of the present utility model is as follows: a kind of oblique ground quartz ampoule structure, it includes quartz ampoule body and quartz pipe cap, described quartz ampoule body one end forms the mouth of pipe, the other end forms drain pipe, described quartz pipe cap one end sleeve is on the mouth of pipe, the other end forms feed tube, at nozzle position, annular projection is formed on described quartz ampoule body, described annular projection is throat structure to the quartz ampoule body between the mouth of pipe, form, on described quartz pipe cap, the flaring structure matched with throat structure, described quartz pipe cap center is fixed with the inner tube being connected with feed tube, said inner tube sleeve is in the mouth of pipe.
As preferably, the outer surface of described throat structure is close to the inner surface of flaring structure, and the inner surface of the outer surface of throat structure and flaring structure is frosting.So substantially increase quartz ampoule body and the sealing of quartz pipe cap junction.
As preferably, described throat structure is 50mm ~ 80mm along the vertical length in direction, quartz ampoule body axis.
As preferably, the angle between sidewall and the quartz ampoule body axis of described throat structure is 10 ° ~ 15 °.
It is suitable at the length of throat structure and inclination, the installation of convenient quartz pipe cap, does not affect the use of quartz ampoule simultaneously.
As preferably, the vertical section of described annular projection is circular arc.Playing spacing effect when annular protrusion is on quartz pipe cap sleeve to quartz ampoule body, prevent the quartz excessive sleeve of pipe cap, destroy quartz pipe cap and quartz ampoule body construction, annular projection is circular arc, plays the effect of buffering.
As preferably, said inner tube external diameter size is 0.7 times ~ 0.8 times of spout diameter size, and said inner tube extends outward quartz pipe cap and the 1/3 ~ 1/2 of extension a length of throat structure length.Inner tube structure makes to be difficult to during fluid injection flow backwards, and does not affect the use of quartz ampoule.
The beneficial effects of the utility model are: arrange annular projection and throat structure by the mouth of pipe one end at quartz ampoule body, quartz pipe cap arranges the flaring structure and inner tube matched, the face, joint of throat structure and flaring structure is frosting, the sealing making quartz ampoule body and quartz pipe cap junction is greatly improved, when liquid is injected by feed tube, it is difficult to flow backwards, improves product quality.

Detailed description of the invention:
In conjunction with a kind of oblique ground quartz ampoule structure of 1,2 pairs of this utility model of accompanying drawing, it is described further.
One of the present utility model oblique ground quartz ampoule structure, it includes quartz ampoule body 1 and quartz pipe cap 2, quartz ampoule body 1 one end forms the mouth of pipe 3, the other end forms drain pipe 4, quartz pipe cap 2 one end sleeve is on the mouth of pipe 3, the other end forms feed tube 5, annular projection 6 is formed near the mouth of pipe 3 position on quartz ampoule body 1, quartz ampoule body 1 between annular projection 6 to the mouth of pipe 3 is throat structure 7, form, on quartz pipe cap 2, the flaring structure 8 matched with throat structure 7, quartz pipe cap 2 center is fixed with the inner tube 9 being connected with feed tube 5, inner tube 9 sleeve is in the mouth of pipe 3.
Further, the outer surface of throat structure 7 is close to the inner surface of flaring structure 8, and the inner surface of the outer surface of throat structure 7 and flaring structure 8 is frosting.
Further, throat structure 7 is 60mm along the vertical length in direction, quartz ampoule body 1 axis.
Further, the angle between sidewall and quartz ampoule body 1 axis of throat structure 7 is 10 °.
Further, the vertical section of annular projection 6 is circular arc.
Further, inner tube 9 external diameter size is 0.8 times of the mouth of pipe 3 internal diameter size, and inner tube 9 extends outward quartz pipe cap 2 and the 1/2 of extension a length of throat structure 7 length.
Operation principle of the present utility model is: during use, and by quartz pipe cap 2 sleeve at the mouth of pipe 3 of quartz ampoule body 1, the outer surface of throat structure 7 is close to the inner surface of flaring structure 8, is formed and seals structure, and inner tube 9 sleeve is in the mouth of pipe 3.
The foregoing is only preferred embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
