Abstract

The invention provides an electronic expansion valve, which comprises: a valve body; a rotor arranged in the valve body; a nut part arranged in the valve body, and the rotor is sleeved on the outside of the nut part; a screw rod is arranged on the nut part , the screw rod is threadedly connected to the nut part, and the rotor is fixedly connected to the screw rod; the first preload spring is arranged in the valve body, the first preload spring is sleeved on the nut part, and the first end of the first preload spring is connected to the rotor, The second end of the first pre-tightening spring is arranged on the nut part, and the first pre-tightening spring is used for providing axial pre-tightening force to the rotor. The technical solution provided by the present application can solve the problem of high noise when the electronic expansion valve in the prior art is in use.

Description

Technical field [0001] The present invention relates to the technical field of electronic expansion valve, and in particular, there is an electronic expansion valve. Background technique [0002] Such as figure 1 As shown, the currently existing electronic expansion valve includes a sleeve 1, a rotor 2, a screw 3, a nut member 4, a valve needle member 5, and a valve seat 6. The screw 3 is threaded with the nut member 4, and the screw 3 is inserted on the nut member 4, and the rotor 2 is sleeved on the nut member 4, and is fixedly connected to the screw 3, and the outer coil can cause the rotor 2 to drive the rotor 2. The screw 3 is lifted down, and the lower end of the screw 3 is coupled to the valve needle member 5, and the valve needle member 5 is lifted together by the screw 3 lifts to control fluid flow. [0003] In the prior art, since the screw 3 and the nut member 4 are threaded connections, the thread has a gap, so that the screw 3 sways when rotating relative to the nut ...
