Sealing device for a homogeniser and homogeniser
The application discloses a sealing device of a homogenizer and the homogenizer. The sealing device comprises a piston and a plunger. The piston comprises a first lip and a second lip on a side of the piston facing the plunger. The first lip and the second lip are arranged in sequence and are spaced apart in the axial direction of the plunger. The first lip and the second lip are arranged around and are attached to the outer circumferential surface of the plunger. The double-lip structure of the first lip and the second lip arranged on the side of the piston facing the plunger is used to scrape off the material adhered to the plunger. The second lip is used to prevent the residual material generated by the friction between the first lip and the plunger from entering the space between the plunger and the piston, thereby improving the sealing effect and prolonging the service life of the sealing device.
