Four-way valve pilot valve for air conditioner as well as equipment and process for mounting capillary tube of four-way valve pilot valve<0}

Abstract

The invention discloses a four-way valve pilot valve for an air conditioner as well as equipment and a process for mounting capillary tubes of a four-way valve pilot valve and belongs to the technical field of four-way valve processing. The four-way valve for the air conditioner comprises a valve body with square cross section, wherein two opposite side surfaces of the valve body are provided with mounting holes; capillary tubes are inserted in the mounting holes; ports of the mounting holes are provided with chamfer structures. <0}{0><}0{>The equipment for mounting the capillary tubes comprises a first conveying rail used for conveying the valve body, wherein a locating mechanism capable of compacting the valve body is arranged above the first conveying rail; two sides of the first conveying rail are respectively provided with a second conveying rail and a third conveying rail which are used for conveying the capillary tubes. Chamfers are optimally designed at the mounting holes of the valve body, so that the valve body and the capillary tubes can be conveniently mounted and positioned; the capillary tubes can be mounted on the valve body by use of the mounting equipment, so that not only the capillary tube mounting accuracy be improved, but also the production efficiency is improved.

Description

technical field [0001] The invention relates to a four-way valve pilot valve for an air conditioner and installation equipment and technology for a capillary tube thereof, belonging to the technical field of four-way valve processing. Background technique [0002] The four-way valve is one of the most widely used valves in the air-conditioning system. The development and application of the four-way valve is no different from a revolution in the history of air-conditioning. The reason why the four-way valve is so popular is that, firstly, it drives the main valve through the pilot valve, adopts pressure difference switching action, and the switching is flexible and reliable; secondly, it can realize the conversion of cooling and heating, and can also be used for defrosting. When there is frost on the outdoor unit of the air conditioner, use it to switch the direction of the refrigerant flow, so that the temperature on the outdoor unit of the air conditioner can be raised to c...

AI Technical Summary

Problems solved by technology

There are several capillary tubes plugged into the pilot valve. The existing technology uses manual installation of capillary tubes, completing the manual installation of multiple tubes one by one, and then tapping with a special copper hammer. The production efficiency is low, the labor intensity is high, and capillary tubes are easy to appear. The port is bad, and the depth of the capillary installed in the valve body is inconsistent. Therefore, it is necessary to improve and optimize the process method of installing the capillary of the four-way valve pilot valve.
