Abstract

The invention discloses a 3D printing and forming integrated program-controlled valve group. The advantage of quick and precise forming of a 3D printing technique is used, so that the integrated program-controlled valve group in which a flow channel is integrated is obtained; multiple complex pipelines and valve components are integrated with the integrated program-controlled valve group in the mode of unit blocks in the prior art, so that an onsite valve area of an adsorption processing system has the advantages of the compact structure, small size and convenience in modularization, skid mounting, equipping and vehicle mounting. Additionally, for the integrated program-controlled valve group, a novel 3D printing and forming process in which a printing and forming process, a permeating process and a sintering process are combined is provided, the quick forming characteristic of 3D printing is taken, after a workpiece is formed, the surface of the inner wall of a complex flow channel issmooth and has excellent antiwear cavitation resistant capability, and the problems of difficulty in processing and forming and poor surface performance of the wall of the flow channel after formingwhen the integrated level of the designed flow channel is overhigh in the skid mounting design process of the valve area of the adsorption processing system are completely solved.

Description

technical field [0001] The invention relates to the field of integrated control valve groups, in particular to an integrated program-controlled valve group formed by 3D printing. Background technique [0002] With the continuous development and progress of industries such as semiconductors and hydrogen fuel cells, the market demand for high-purity gases including hydrogen and ammonia is increasing, and the quality requirements are also getting higher and higher. In addition, due to the high cost and low utilization rate of the high-purity gas used, the separation, purification, recovery and reuse of the corresponding gas has also become one of the focuses of enterprises. [0003] As the most effective gas deep separation and purification technology at present, temperature swing adsorption and pressure swing adsorption, both of which use molecular sieves carrying gas adsorbates to have different adsorption properties for different gas molecules under different temperature or ...
