The invention discloses a thermostatic expansion valve and a manufacturing method thereof. The thermal expansion valve comprises a transmission part, a valve core assembly and a valve body assembly. The valve body assembly comprises a valve body and a sleeve assembly, the valve body and part of the sleeve assembly are fixedly arranged or arranged in a limiting manner, part of a valve rod is located in a limiting channel of the expansion valve, and a sealing piece is in interference fit with the valve rod. Therefore, the inner sealing performance of the thermal expansion valve can be improved through the interference fit between the outer peripheral side of the sealing piece and the inner peripheral side of the sleeve assembly and the interference fit between the inner peripheral side of the sealing piece and the outer peripheral side of the valve rod.

    本发明公开一种热力膨胀阀及其制造方法,包括传动部件、阀芯组件及阀体组件,阀体组件包括阀体、套筒组件,该阀体与部分套筒组件固定设置或者限位设置,其中部分阀杆位于膨胀阀的限位通道内,密封件与阀杆过盈配合,从而通过密封件的外周侧与套筒组件的内周侧过盈配合,该密封件的内周侧与阀杆的外周侧过盈配合,可提高热力膨胀阀的内部密封性能。
