Problems solved by technology
During the manufacturing process, valves need to be connected through tees, crosses, and pipes, and skilled workers with operating certificates (such as welding qualifications) are required, resulting in low production efficiency and high labor costs.
During the manufacturing process, valves need to be connected by three-way, four-way, and pipes. Welding between pipes will consume time and labor, resulting in low production efficiency and high labor costs; There will be too many potential leakage points, which will affect the working reliability and performance of nitrogen making equipment

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0027] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on another element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way in which an element is fixedly connected to another element may be achieved through existing technologies, and will not be discussed here. To repeat it aga...

The invention discloses a pressure swing adsorption equipment combination valve. The pressure swing adsorption equipment combination valve comprises a valve seat body, a first valve, a second valve and a pressure equalizing valve, wherein the valve seat body is provided with a first mounting part, a second mounting part and a third mounting part; the first valve is used for sucking air or producing air and is arranged on the first mounting part; the second valve is used for sucking air or producing air and is arranged on the second mounting part; the pressure equalizing valve is arranged on the third mounting part; the first valve, the second valve, the pressure equalizing valve and the valve seat body are of an integrally formed structure. Thus, the combination valve is directly mounted on an adsorption tower for use without conducting welded connection on the valves, communicating parts and pipes. The production time is shortened. The labor intensity of workers is reduced. The production efficiency is improved. Potential safety hazards are eliminated. The use performance and operational reliability of equipment are improved.
Description
technical field [0001] The invention relates to the technical field of pressure swing adsorption, in particular to a combination valve of pressure swing adsorption equipment. Background technique [0002] Currently, multiple valves and connecting piping are usually required in conventional PSA equipment. For example, the nitrogen-generating equipment with eight-valve structure consists of two exhaust valves, two intake valves, two gas production valves, one upper pressure equalizing valve, one lower pressure equalizing valve, two exhaust valves, two The intake valve and the lower pressure equalizing valve are connected through pipelines, and the two gas production valves and the upper pressure equalizing valve are connected through pipelines. During the manufacturing process, valves need to be connected through tees, crosses, and pipes, requiring skilled workers with operating certificates (such as welding qualifications), resulting in low production efficiency and high lab...
