Title:
T-SHAPED VALVE AND COMBINED REVERSING VALVE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/198103
Kind Code:
A1
Abstract:
Disclosed is a T-shaped valve (1) consisting of a lower valve body (4), an upper valve body (5), a guide column (17), and an external force member (20). The T-shaped valve (1) and an auxiliary valve (2) can be combined to form a T-shaped valve type water inlet valve (3). Two T-shaped valves (1) can be combined to form a two-position reversing valve (34), four T-shaped valves (1) can be combined to form a T-shaped valve type three-position reversing valve (35) by means of logical combination, and four T-shaped valve type water inlet valves (3) can be combined to form a three-position reversing valve (36) by means of logical combination. The reversing valve can be converted into a reversing valve having pressure limiting and unloading functions by arranging the T-shaped valve (1) in a proper position of the reversing valve, a spring (15) and a handle being disposed at the end of a post channel (11). By changing the relative position relationship between the external force member (20) or a transaction member (38) and a post on the reversing valve, the circulation and the cut-off of a fluid medium in a pipeline and the flowing direction of the fluid medium in the pipeline can be changed, so that the reversing valve has different operating states. The T-shaped valve (1) and the T-shaped valve type water inlet valve (3) can also be separately used. The reversing valve has a simple structure and is free of internal leakage, the flowing direction of the fluid medium can be stably changed in the pipeline, median functions are complete, and the manufacturing process of the reversing valve does not need a high precision.
