Abstract

The invention discloses a fluid communication switching device and relates to the technical field of fluid pipeline control. The device is used for fluid abrasive dust processing and is longer in service life. According to the technical scheme, a shell body is provided with a top wall and a surrounding wall, a first accommodating groove is formed in the inner surface of the surrounding wall, a fixed valve element is arranged in the shell body, a movable valve element is arranged in the shell body, the first end face of the movable valve element is in surface contact with the first end face of the fixed valve element in a matched mode, a check ring is arranged in the first accommodating groove and located between the movable valve element and the first accommodating groove, a rotary connecting piece is connected with the movable valve element, a driving device comprises a driving shaft which is connected with the rotary connecting piece, and a position selection device is used for controlling the driving device to rotate. The device is mainly used in the technical field of fluid analysis.

Description

technical field [0001] The invention relates to the technical field of fluid pipeline control, in particular to a fluid communication switching device. Background technique [0002] The existing fluid communication switching device includes a housing, a fixed valve core disposed in the housing, a movable valve core disposed in the housing, and a driving device disposed in the housing. When the fixed valve core and the dynamic valve core are tightly sealed Next, when the movable spool rotates to different angles under the drive of the driving device, the multiple fluid passages on the fixed spool communicate correspondingly through the guide grooves on the movable spool to realize the switching control of the fluid. Due to the long-term use of the fluid communication switching device, fluid debris will be generated at the joint between the fixed valve core and the moving valve core. If the fluid debris exists in the fluid communication switching device for a long time, it wil...
