Abstract
The invention relates to a paraffin switching valve for a tissue dehydrator. The paraffin switching valve comprises a rotating valve core and a valve sleeve, wherein the valve sleeve is provided with a hollow cavity matched with the rotating valve core; at least two paraffin inlet pipelines communicated with the hollow cavity are formed on the valve sleeve; a paraffin feeding pipeline is formed on the rotating valve core correspondingly; the inlet of the paraffin feeding pipeline is communicated with the paraffin inlet pipelines correspondingly through rotation; and the outlet of the paraffin feeding pipeline is connected with the tissue dehydrator. By adoption of a photoelectric switch, precise control is realized; by the structure of the distribution valve core, the volume and the friction face are reduced, the driving power is lower, the rotation is more sensitive, the motion is more standard, the sealing effect is enhanced and the liquid leakage is avoided. The paraffin switching valve for the tissue dehydrator is novel in idea and easy to manufacture; due to the liquid feeding pipeline, corresponding to the valve sleeve, of the rotating valve core, the paraffin liquid is more accurate to switch; and the photoelectric switch is adopted to control the work of a driving device, so automated control is realized and the switching is more accurate and quicker.
