Abstract

The invention belongs to an electric throttling distributor for a refrigerating system, which comprises a casing, an inlet, an inlet connecting pipe, a plurality of throttling holes, outlet connecting pipes and a stepping motor for driving, wherein the inlet connecting pipe is communicated with the inlet; the outlet connecting pipes are respectively communicated with the throttling holes. The interior of a valve cavity in the casing is also provided with an actuating part which is driven by a magnetic rotor part; the actuating part comprises a driving rod and a slide valve, wherein the slide valve is arranged opposite to the throttling holes. The stepping motor drives the slide valve to rotate to realize flow distribution between the throttling holes and a positioning mechanism is arranged between a rotatable rotating part and a fixing part in the valve cavity. The position relationship between the slide valve and the throttling holes is ensured by the positioning of the positioning mechanism; meanwhile, the system has the advantages of simple installation and connection, and low manufacturing cost.

Description

technical field

[0001] The invention belongs to an electric throttling distributor for a refrigeration system, in particular to an electric throttling distributor 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 through distributors and expansion valves, such as the invention patent application number 200610145015.2 filed on November 29, 2006 The solution disclosed in the application publication specification uses 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 drag multiple air conditioners .
