Abstract
The present invention discloses a valve body device for an electric control valve comprising a valve seat (21) and a fixing frame (22) connected with the valve seat (21), wherein, the valve seat (21) is provided on its outer wall with a first positioning groove (211) extending circumferentially, and the direction towards which the first positioning groove (211) opens is perpendicular to the axial direction of the valve seat (21), and wherein, the fixing frame (22) is provided with a positioning flat plate portion (221) fitted with the first positioning groove (211), and the positioning flat plate portion (221) is inserted into the first positioning groove (211) and fixedly connected with the valve seat (21). The fixing frame of the valve body device may be mounted on the valve seat after the valve seat and the cap is welded, which may prevent the fixing frame from being damaged, and may allow the fixing frame and the valve seat to be positioned accurately with each other and thus to be welded in a convenient and reliable way. The present invention also discloses an electric control valve including the above described valve body device.
