Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] like Figure 2 to Figure 6 As shown, the electronic expansion valve of this embodiment includes: a valve body 10 , a valve needle 20 , a driving part, and a noise reduction part. Among them, the valve body 10 has a valve port 11; the valve needle 20 has a closed position for closing the valve port 11 and an open position for avoiding the valve port 11; the driving part drives the valve needle 20 to move between the closed position and the open position; On the valve needle 20, the valve port 11 is provided with an upward protruding annular protrusion 40, and the muffler is located on the circumferential outer side of the annular protrusion 40. When the valve needle 20 is in the closed p...

Abstract

The invention provides an electronic expansion valve and refrigeration equipment with the same. The electronic expansion valve comprises a valve body provided with a valve port, a valve needle provided with a closed position for closing the valve port, and an open position avoiding the valve port, a driving part driving the valve needle to move between the closed position and the open position, and a silencing part arranged on the valve needle in a sleeving manner, wherein the position of the valve port is provided with an annular protruding part stretching out upwards; and the silencing part is located on the outer side of the peripheral direction of the annular protruding part, and when the valve needle is located at the closed position, an overlapped segment is formed between the silencing part and the annular protruding part. By means of the technical scheme, the problem that an electronic expansion valve in the prior art is large in noise can be effectively solved.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an electronic expansion valve and a refrigeration device having the same. Background technique [0002] like figure 1 As shown, in the prior art, the deceleration electronic expansion valve is mainly composed of two parts, one part is the valve body part for flow regulation, and the other part is the coil part for driving. The coil part includes: a permanent magnet stepper motor 1, a gear reducer 2 with three-stage reduction, a threaded secondary structure 5 that converts the motor rotation motion into the vertical motion of the screw rod 3, the valve body includes a valve seat 10, and a control valve. Core components such as the bellows 7 that the valve needle 8 lifts and lowers constitute. The working principle of the above-mentioned electronic expansion valve is introduced below: first, the electronic controller of the air-conditioning system controls the rotation of the output ...
