Embodiment approach

[0024] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the first embodiment of the electric flow distribution mechanism of the present invention. The electric flow distribution mechanism includes a shell 709 and a base part, the base part is composed of a base 714 and a bottom plate 717; the shell 709 and the base part together form a valve cavity 710, a part of the base 714 and the bottom plate 717 are fixed on the In the valve cavity; outside the casing 710, a coil part 711 as a stepper motor stator part is fixed, and a magnetic rotor part 707 as a stepper motor part is also provided in the casing, which can be driven back and forth by the magnetic rotor part 707. The rotating drive shaft 708 and the spool valve 706 that rotates with the magnetic rotor part and the drive shaft, the spool valve 706 is arranged opposite to the bottom plate 717 and fixed on the axial position along the drive shaft, the drive shaft 708 is injection molded through the...

no. 3 approach

[0031] Figure 5 It is the third embodiment of the present invention. The difference between this embodiment and the above-mentioned second embodiment is that the base part is an integrally formed base 705, and the base 705 and the housing 709 together form a valve cavity 710. The upper part of the base 705 The half part is fixed in the described valve chamber; the stepper motor used for driving in this embodiment also includes the coil part 711 fixed outside the housing 709 as the stator part of the stepper motor and the coil part 711 as the mover part in the housing. The magnetic rotor part 707 opposite to the magnetic pole of the coil part; in addition, it also includes a transmission shaft 708 that can rotate back and forth under the drive of the magnetic rotor part and a slide valve 706 that rotates with the magnetic rotor part and the transmission shaft; the transmission shaft 708 is passed through the magnetic rotor part. It is fixed and formed together during injection...

Abstract

The invention belongs to an electric flow distributor mechanism for a refrigeration system, which comprises a shell, a base part, an inlet, an inlet adapter pipe which is communicated with the inlet, a plurality of outlets and outlet adapter pipes which are communicated with the outlets, and also comprises a stepper motor for driving, a drive shaft driven by the stepper motor and a guiding valve,wherein the stepper motor comprises a coil part fixed outside the shell and a magnetic rotor part arranged in the shell; the shell and the base part form a valve cavity; the inlet adapter pipe is communicated with the valve cavity; the plurality of outlets are formed on the base part; and a bearing is arranged between the drive shaft and the base part to avoid the direct contact between the driveshaft and the base part so as to reduce the rotating resistance of the drive shaft and consequently reduce driving power. The electric flow distributor mechanism realizes the dynamic intelligent distribution of a flow among the plurality of outlets by using the stepper motor to drive the drive shaft and the guiding valve in the valve cavity to rotate.

Description

technical field [0001] The invention belongs to an electric flow distribution mechanism for a refrigeration system, in particular to an electric flow distribution mechanism for performing dynamic and intelligent flow distribution before a multi-channel heat exchanger for an air-conditioning system. Background technique [0002] Most air-conditioning systems in the prior art include indoor heat exchangers, outdoor heat exchangers, compressors, and throttling devices. The flow distribution has always been a technical difficulty; many systems use electronic expansion valves to individually control each indoor unit and distribute the flow, as disclosed in the publication of the invention patent application number 200610145015.2 filed on November 29, 2006 The solution is to use a control valve module for each indoor unit to intelligently adjust the electronic expansion valve of each indoor unit, so as to realize the on-demand distribution of the refrigerant flow of one-to-many ai...
