Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in Fig. 1, the frame of the brass pipe nitrogen flushing device of the present invention comprises two positioning plates 2, 16 arranged in parallel, four corners of the two positioning plates are provided with four guide posts 21 parallel to each other, and the guide posts and the positioning plates pass through The connectors are connected into one body. Two cylinder fixed plates 4,22 parallel to the positioning plate are located on four guide posts 21, and a bushing 20 is arranged between the sleeve hole of the fixed plate and the guide post, and the bushing 20 and the guide post 21 are slidably matched, so that the two The fixing plates 4 and 22 can slide on the guide post 20 under the promotion of the cylinder 3 .

[0014] The cylinder 5 is fixed on the two fixing plates 4 and 22 with screws, and a rubber sealing plate 6 ...

Abstract

The invention relates to the rushing nitrogen setting used in the copper pipeline includes four parallel guiding pole and the orienting board A and B fixed on the two ends of the guiding pole. Two slipping fixing board A and B are fixed on the four guiding poles, the gas jar B copulating airproofly with the fixing board B is fixed on the two fixing board, the air jar used for pushing the two fixing boards to slip is fixed on the orienting board A and the fixing board; the end of the gas pushing pole of the said air jar B has the pressing nob of which the head part can be installed the stifled nob, the air pressing pole with the pressing nob has the pressing cover connected airproofly with the fixing board B, the pressing cover has the mouth for the stifled nob passing; the said orienting board B has the copper pipeline setting copulating with pressed cover assuming the pressurizing surface, the setting has the nip-hold hole used for the pulled on of the copper tube, the said nip-hold hole are setup with the said pressing nob and the pressing cover, they have the same axes. The setting can crush the high pressure nitrogen to keep the certain air pressure in copper tube and protect the inner surface of the copper tube.

Description

technical field [0001] The invention relates to a nitrogen flushing device for copper tubes. The device injects high-pressure nitrogen gas into the copper tubes at normal temperature to keep the copper tubes with high-purity high-pressure nitrogen gas to ensure the quality requirements of the copper tubes used in air conditioners. Background technique [0002] The function of injecting high-pressure and dry nitrogen into the copper tube is to make the copper tube free from pollution, oxidation and moisture, and to protect the inner wall of the copper tube by nitrogen. But as far as the country is concerned, there is no device dedicated to high-pressure and pure nitrogen for copper pipe punching. What is adopted abroad is a method of dripping liquid nitrogen into the copper tube. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nitrogen flushing device for copper tubes in view of the above-mentioned current stat...
