Clean compressed air conveying pipeline system

Abstract

The invention belongs to the technical field of compressed air conveying, and particularly relates to a clean compressed air conveying pipeline system. The clean compressed air conveying pipeline system comprises a first pipeline and a second pipeline, and the second pipeline is connected to the right end of the first pipeline; the clean compressed air conveying pipeline system further comprises a backflow preventing device; the backflow preventing device is arranged in the second pipeline; the backflow preventing device comprises an air blocking seat and a supporting seat; the air blocking seat and the supporting seat are installed in the second pipeline; a first inserting barrel is installed at the side end of the gas blocking seat; a first inserting rod is inserted into the inner side of the first inserting barrel; a second inserting barrel is installed at the side end of the supporting seat; a second inserting rod is inserted into the inner side of the second inserting barrel; a clamping seat is installed between the second inserting rod and the first inserting rod; a rubber pad is installed at the inner side of the clamping seat; and an air inlet is provided on the inner wall of the air blocking seat. The clean compressed air conveying pipeline system has the beneficial effects that: the backflow preventing device is arranged in the second pipeline, air pushes the clamping seat to move, then the clamping seat controls the air outlet to be opened and closed, and air backflow is prevented from polluting clean compressed air.

Description

technical field [0001] The invention relates to the technical field of compressed air delivery, in particular to a clean compressed air delivery pipeline system. Background technique [0002] All high-purity and high-clean gases in the clean compressed air pipeline system need to be transported to the point of use of the instrument through the pipeline. In order to meet the quality requirements of the instrument for the gas, when the gas outlet index is certain, more attention should be paid to the piping system. Material selection and construction quality, in addition to depending on the accuracy of gas production or purification equipment, are largely affected by many factors in the pipeline system. Compressed air, that is, air compressed by external forces, has compressibility. Compressed air is an important source of power. Compared with other energy sources, it has the following obvious characteristics: clear and transparent, easy to transport, and no special Hazardous...

Problems solved by technology

[0006] Therefore, the purpose of the present invention is to provide a pipeline system for clean compressed air. By installing an anti-backflow device in the second pipeline, the air pushes the deck to move, and then controls the opening and closing of the outlet of the air through the deck to prevent the backflow of air from polluting the clean air. High-quality compressed air can solve the above-mentioned problem that after the clean compressed air is transported, a certain amount of gas remains on the metal surface, various pollutants stick in the air, and the air is prone to backflow, re-entering the pipeline and polluting the pure gas.
