AI Technical Summary
Technical Problem
Existing rotary joints experience excessively high internal temperatures during use, making their internal structure prone to damage. Furthermore, frictional contact at the silicon carbide contact points results in a short service life.
Method used
It adopts an automatic opening and closing structure with silicon carbide wafers, and utilizes a water-cooled heat dissipation shell and sealing ring design. Cooling water circulation is achieved through water-cooled inlet and outlet holes. Combined with a return spring and sealing ring, frictional contact is reduced and service life is increased.
Benefits of technology
It effectively reduces internal temperature, minimizes frictional contact, extends service life, and improves the durability and safety of rotary joints.

Abstract
The utility model discloses a silicon carbide sheet automatic opening and closing water-cooled rotary joint, which comprises a first shell and a special-shaped bearing sleeve, the inside of the first shell is connected with a movable head through two first sealing rings, and one end of the movable head is connected with a water delivery pipe through a first silicon carbide sheet and a second silicon carbide sheet. A reset spring is arranged between the movable head and the water conveying pipe, and the outer side of the special-shaped bearing sleeve is sleeved with a water-cooled heat dissipation shell. Contact is adjusted through the first silicon carbide sheet and the second silicon carbide sheet, that is, the first silicon carbide sheet and the second silicon carbide sheet are contacted together when water enters and are in a disconnected state when not working, so that friction in normal use is reduced, and the service life is prolonged; the water-cooled heat dissipation shell conveys cooling water into the spiral water channel on the inner wall through the water-cooled water inlet hole and the water-cooled water outlet hole, so that the cooling water can conduct heat dissipation and cooling treatment on the special-shaped bearing sleeve, the temperature of the special-shaped bearing sleeve is lowered through the cooling water, and the safety of the internal structure is kept.
