Problems solved by technology

Therefore, for example, there are concerns about the unevenness of the upper surfaces of the valve body and the flange-shaped plate due to the solder adhering to the upper surface of the valve body and the flange-shaped plate on which the stopper foot is placed and fixed. (surface accuracy) deviation, etc., the stopper foot is arranged obliquely with respect to the valve body and the flange-shaped plate, and there is a gap between the stopper foot, the valve body, and the flange-shaped plate, making it impossible to accurately Fix the stopper foot

Abstract

The present invention provides an electric valve, capable of accurately configuring and fixing a stopper presser foot with respect to a valve body and a flange-shaped plate. In the stopper presser foot (48), an exterior support portion (48a) attached to a lower stopper (25) is disposed apart from the valve body (40), and a mounting fixing portion (48b) is fixedly arranged at the outer periphery ofthe exterior support portion (48a); and the flange-shaped plate (47) is fixed on the valve body (40).

Description

technical field [0001] The present invention relates to an electric valve used as a flow control valve and the like, which is assembled in refrigeration cycles such as air conditioners and refrigerators. Background technique [0002] As such an electric valve, for example, a structure is known, which includes: a valve shaft with a valve core provided at the lower end; and a cylindrical part that can be inserted in a relatively rotatable state; the valve main body has a valve seat part (valve seat) that is in contact with and separated from the valve core, and the guide bush is installed and fixed; the valve shaft holds The valve shaft holder has a cylindrical portion and a top, and is connected and fixed with the valve shaft, the cylindrical portion is inserted into the guide bush, and the top is provided through the upper end of the valve shaft. The insertion hole through which the part is inserted; the force application part, which is inserted between the valve shaft and ...
