Abstract

The invention provides an electronic expansion valve and a refrigerating system with same. The electronic expansion valve comprises a valve body, a valve needle, a valve rod, a first silencing part, afirst sealing part and a driving part; the valve body is provided with a first valve port; the valve needle is provided with a closing position and an opening position, the bottom of the valve needleis provided with a second valve port, the valve needle is provided with a containing space, a first flowing channel and a second flowing channel, the first flowing channel communicates with the outside, and the second flowing channel communicates with the second valve port; the valve rod is at least partially arranged in the containing space in a penetrating mode; the first silencing part is arranged in the containing space; the first sealing part is arranged in the containing space and is positioned between the first silencing part and the second flowing channel, a third flowing channel is formed in the first sealing part, and the containing space communicates with the second flowing channel through the third flowing channel; and the driving part drives the valve rod to move up and down.By means of the technical scheme, the problem of large noise of the electronic expansion valve in the prior art 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 system having the same. Background technique [0002] Such as figure 1 As shown, in the prior art, the deceleration electronic expansion valve for inverter air conditioner 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 Core components such as the bellows 7 that control the lift of the valve needle 8 are formed. The working principle of the above-mentioned electronic expansion valve is introduced below: first, the electronic controller of the air-conditioning system controls the rota...
