Zusammenfassung:	The utility model relates to a valve core component used for preventing noise, which comprises a valve core frame, a steel ball and a transmission rod. The utility model is characterized in that the valve core frame, the steel ball and the transmission rod are fixedly connected with each other in sequence. In the utility model, the valve core frame, the steel ball and the transmission rod are welded with each other to form into the valve core component with an integral structure through the combination of the transmission rod in the existing structure by an upper transmission rod and a lower transmission rod. When a thermostatic expansion valve works, noise caused by the longitudinal impact of the steel ball and the lower transmission rod, the upper transmission rod and the lower transmission rod, and the lower transmission rod and a valve body in the existing structure can be eliminated.
