Description

Fluid blocking device for centrifugal machine

Technical Field

The utility model belongs to the technical field of the centrifuge technique and specifically relates to a fluid blocking device for centrifuge is related to.

Background

A fluid is a flowable substance, which is a body that deforms continuously under any slight shear force. Fluids are a generic term for liquids and gases. The fluid blocking means, as the name implies, is to block gas or liquid when the liquid and the liquid are mixed to flow, so that only a single fluid can flow and backflow cannot occur.

The existing centrifugal machine has no special fluid blocking device, and most of the existing centrifugal machines use a check valve for fluid blocking, wherein the check valve is a valve of which the opening and closing piece is a circular valve clack and acts by self weight and medium pressure to block media from flowing backwards, so that the check valve can not block gas mixed in liquid or liquid mixed in gas.

Therefore, there is a need to provide a new technical solution to overcome the above-mentioned drawbacks.
