Zusammenfassung:	The utility model belongs to pneumatic technique, and relates to a control valve component for inflating and air pressure checking of a landing system, which comprises a casing (1), two on-off valves and four pipe connectors with sealing caps, wherein the two on-off valves and the four pipe connectors are mounted in the casing (1). The upper end of a first on-off valve (2) is serially connected with the right ends of a second pipe connector (5) and a first pipe connector (4) through pipelines, and the left end of the first pipe connector (4) is communicated with the upper end of a second on-off valve (3). The lower end of the first on-off valve (2) is serially connected with the right ends of a third pipe connector (6) and a fourth pipe connector (7), and the left end of the pipe connector (7) is communicated with the lower end of the second on-off valve (3). By means of the control valve component, repeated mounting and dismounting of inflating tools and deflating tools can be avoided, and thereby inflating
