Abstract

The invention provides a combined four-way valve. The combined four-way valve comprises a main valve, a guide valve and a fixing structure, wherein the main valve comprises a first valve body and a connecting seat; circulation holes are formed in the first valve body; the connecting seat corresponds to the circulation holes and is used for installing a main valve pipe; the guide valve is arranged on the connecting seat; and the fixing structure is arranged between the guide valve and the connecting seat, and is used for limiting the position of the guide valve on the connecting seat. According to the technical scheme provided by the invention, the problems that in the prior art, the structure is complex, and assembling is not convenient can be solved.

Description

technical field [0001] The invention relates to the technical field of four-way valves, in particular to a combined four-way valve. Background technique [0002] At present, the four-way valve includes a main valve and a pilot valve, and the pilot valve is connected to the main valve through a bracket and a capillary. When assembling the pilot valve, first weld the bracket on the main valve body, then fix the pilot valve on the bracket by riveting, welding or screwing, and then put the d / c / e / s capillary into the specified position, and finally welded to fix. [0003] However, with the structure in the prior art, since multiple parts of the bracket and the capillary need to be assembled, the installation process is cumbersome, the assembly time is long, and the production cost is high. Therefore, there are problems of complex structure and inconvenient assembly in the prior art. Contents of the invention [0004] The invention provides a combined four-way valve to solve ...
