Problems solved by technology

Since the rotor assembly in this structure (including the rotor connecting plate and the magnetic rotor) is directly welded and fixed to the screw, when the product has poor performance such as internal leakage and large flow deviation, the rotor assembly can only be scrapped, which increases the cost of product trial production ; In addition, the existing guide piece and the rotor connecting plate need to be welded and fixed, which further increases the cost of trial production

Abstract

The invention provides an electronic expansion valve. The electronic expansion valve includes a rotor assembly, a screw (1) and a guide piece (2). The rotor assembly is sleeved outside the screw (1), and the guide piece (2) forms a circumferential limit with the rotor assembly. The guide piece ( 2) It is welded and fixed to the screw rod (1), and the rotor assembly drives the screw rod (1) to rotate through the guide piece (2). According to the electronic expansion valve of the present invention, the cost of product trial production can be reduced, and the utilization rate of product components can be improved.

Description

Technical field [0001] The present invention relates to the field of refrigeration and air conditioning technology, in particular, it relates to an electronic expansion valve. Background technique [0002] Conventional valve head from the balance structure of the electronic expansion valve, which member comprises a rotor magnet rotor, rotor webs, guiding the movable piece, the movable guide plate provided on the rotor and the rotor web and the stepped stopper secured web; the expansion valve assembly when the first product is determined by the rotation of the screw set to zero, then the rotor is sleeved on the screw member, rotation of the rotor and the movable member so that the guide plate and stopper ring contacts the stopper, the screw and the rotor web assembly by laser welding etc. fixedly connected. Since the rotor assembly of the structure (the connecting plate and the magnet rotor comprises a rotor) directly soldered fixedly connected with the screw, so that when the pro...
