Integrated program-controlled valve group

Abstract

The invention discloses an integrated program-controlled valve group. The integrated program-controlled valve group comprises a valve group body, multiple unit blocks are arranged on the valve group body, multiple collecting runners connecting with the unit blocks in a left and right manner are arranged at the bottoms, air inlet runners, air outlet runners and multiple branch runners in one-to-onecorresponding to the collecting runners are arranged in the unit blocks, the air inlet runners and the air outlet runners connect with the unit blocks in a front and back manner, one end of each branch runner communicates with the corresponding air outlet runner, the other end of each branch runner communicates with the corresponding collecting runner, and a controllable valve is arranged on eachbranch runner. Fixing parts used for connecting with the exterior are formed in openings, formed by the air inlet runners, the air outlet runners and the collecting runners, of the surfaces of the unit blocks. Multiple complex pipelines and valve parts are integrated in the integrated program-controlled valve group in a unit block mode, the valve area structure is compact, the size is reduced, modular, skid-mounting, equipment and vehicle-mounted aims can be achieved, a large amount of pipelines and pipeline joints can be saved, cost is saved, seal is good, reliability is high, and safety ishigh.

Description

technical field [0001] The invention relates to the field of integrated control valves, in particular to an integrated program-controlled valve group. 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 pressure conditions to achie...
