Abstract

The invention discloses a planetary reducing mechanism for a four-way switching valve. The mechanism comprises a switching valve disc, a first planetary gear, a planetary gear disc, an inner driving wheel, an inner gear ring, a central shaft and a bearing disc, and the central shaft sequentially penetrates through a first through hole of the switching valve disc, a second through hole of the planetary gear disc and a third through hole of the inner driving wheel to be connected with a through hole of the bearing disc; the first planetary gear is installed on a first positioning shaft of the switching valve disc and a second positioning valve of the planetary gear disc, the planetary gear disc and the first planetary gear are embedded in the inner gear ring, and the inner gear ring is fixedand static and arranged between the switching valve disc and the inner driving wheel. The planetary reducing mechanism has the advantages that large torque can be achieved, so that reliable switchingis ensured, the assembly is simple, the cost of materials is low, the processing cost is low, and therefore the cost is reduced.

Description

technical field [0001] The invention relates to a planetary reduction mechanism for a four-way reversing valve. Background technique [0002] At present, the four-way reversing valve at home and abroad adopts the pilot electromagnetic control structure, that is, the reversing valve is controlled by the pilot electromagnetic valve. This structure is not only costly, but also complicated. This structural method uses air pressure to push the slider to achieve reversing. This reversing method not only requires high precision parts, but also requires the friction coefficient between the slider and its matching components to be small, and even good sealed structure. Contents of the invention [0003] The purpose of the present invention is to provide a planetary reduction mechanism for a four-way reversing valve, through which a large torque can be achieved, thereby realizing reversing. This structure not only performs reliably, but also at low cost. [0004] In order to achi...
