Abstract:
The invention provides an electrically operated valve and a refrigeration cycle system. The electrically operated valve is provided with a structure capable of assembling an accommodating housing and a valve main body part in a highly precise and consistent manner without complicated assembly precision management. An electrically operated valve (100) is provided with: a rotor shaft (131) fixed to the central axis (CL) of a magnetic rotor (141) and having a male screw part (131a); a valve body housing (111) in which a valve chamber, a port, and a joint are formed; a female screw member (132) having a female screw section (132b) formed thereon, the female screw section (132b) being screw-coupled to the male screw section; a fixing metal member (133) formed in a plate shape and integrally fixed to the female screw member; and a cup-shaped accommodating housing (151). The outer periphery of the fixed metal part is provided with a guide part (133c) which is formed along an imaginary circle (CI) with the radius being the farthest part from the central axis and is embedded into the inner side of the accommodating shell; and a welding part (133d) which is welded and fixed to the joint part of the valve main body housing at a part other than the guide part.
