Description
Technical Field
The invention relates to a cooling system, in particular to a vacuum cavity cooling water pipe sealing interface.
Background
The traditional vacuum cavity cooling water pipe sealing interfaces existing in the market at present are divided into two types, namely, a cooling water pipe is directly welded with a vacuum cavity sealing flange, the structure is very simple, but the welded part is changed in cold and hot alternation, so that a welded joint is extremely easy to crack and leak; if low temperature soldering is used, the flux may also contaminate the vacuum chamber. Secondly, a rubber ring compression sealing mode is adopted, but the rubber ring is easy to age and lose efficacy along with the alternating change of time and cold and heat; and the leakage rate of the rubber ring in a high vacuum or vacuum sealing device is too high to meet the requirement of a vacuum device.
Therefore, the vacuum cavity cooling water pipe sealing interface with the traditional structure mainly has the following defects:
(1) Seal is easy to fail
(2) The sealing cavity is easily affected by cold and heat alternation
(3) The sealing cavity is easy to pollute
(4) Has low service life

The invention relates to a novel vacuum cavity cooling water pipe sealing interface, which comprises a sealing flange for vacuum sealing, a cooling water pipe for cooling, and a transfer welding ring which is used for transfer and heat insulation and contains a heat insulation groove, and is characterized in that: the novel vacuum cavity cooling water pipe sealing interface is additionally provided with and adopts a switching welding ring which is used for switching and is heat-insulating and contains a heat-insulating groove.
Preferably, the novel vacuum cavity cooling water pipe sealing interface is additionally provided with and adopts a switching welding ring which is used for switching and is heat-insulating and comprises a heat-insulating groove.
Preferably, the transfer welding ring is provided with a heat insulation groove on the structural layout, and the wall thickness of the heat insulation groove part is smaller than that of the welding ring part.
Preferably, one end of the transfer welding ring with the heat insulation groove is welded in the vacuum sealing flange connecting hole, and the other end is welded with the cooling water pipe.
Preferably, the transfer welding ring and the vacuum sealing flange are welded by silver-copper brazing.
Preferably, the transfer welding ring and the cooling water pipe are welded by argon arc welding.
Preferably, the novel vacuum cavity cooling water pipe sealing interface is fixed and unchanged in assembling and welding mode, so that pollution caused by welding materials to the sealing cavity is reduced and eliminated.
The novel vacuum cavity cooling water pipe sealing interface is additionally provided with the transfer welding ring provided with the heat insulation groove, and after the vacuum sealing flange is welded with the transfer welding ring through silver copper brazing, the welded junction is separated by the heat insulation groove and is far away from the part with frequent cold-hot alternation, so that the external condition factors of crack leakage of the welded junction are reduced, and the service life of a vacuum device is prolonged; in addition, after the cooling water pipe welding ring is welded with the switching welding ring, the wall thickness of the cooling water pipe welding ring and the wall thickness of the cooling water pipe welding ring are close, and the cold and hot expansion rate of the cooling water pipe welding ring and the switching welding ring are close, so that the influence of cold and hot changes on argon arc welding junctions is small, and the reliability of a vacuum cavity cooling water pipe sealing interface is improved. Therefore, compared with the traditional cooling water pipe sealing interface, the novel vacuum cavity cooling water pipe sealing interface has the advantages of compact and reliable structure, long service life and low cost.
