Description

Three-way mechanical seal slip ring Technical Field The application relates to the technical field of three-way sealing, in particular to a three-way mechanical sealing slip ring. Background The three-way mechanical seal slip ring is a composite device integrating mechanical seal technology and multi-channel transmission function, can realize the sealed transmission of three independent media (such as hydraulic oil, cooling liquid, gas and the like) under the rotating working condition, has the capability of preventing leakage and synchronously transmitting the media, and has the core of ensuring the tightness through a face seal structure matched with a dynamic ring and a static ring, and simultaneously realizes multi-medium synchronous transmission by using a layered channel design. However, the existing three-way mechanical sealing slip ring is inconvenient to detect and pre-warn safety, so that operators cannot find out signs of sealing failure in time, and sudden severe leakage can be caused. Disclosure of utility model The utility model aims to solve the defects that in the prior art, detection and safety pre-warning are inconvenient, so that operators cannot find out signs of sealing failure in time, and sudden severe leakage can be caused. The application provides a three-way mechanical seal slip ring, which adopts the following technical scheme: A three-way mechanical seal slip ring comprising: The main shaft is provided with a first rotor air inlet, a second rotor air inlet and a third rotor air inlet; The first shell is arranged on the main shaft, the second shell is arranged on the first shell, the third shell is arranged on the second shell, the fourth shell is arranged on the third shell, leakage holes are formed in the first shell and the third shell, and the first stator air outlet, the second stator air outlet and the third stator air outlet are respectively formed in the second shell and the third shell; and the connecting assembly is arranged on the second shell. Further, a first stationary ring is arranged on the first shell and the third shell, and a second stationary ring is arranged on the second shell. Further, the connecting assembly comprises a connecting piece, the connecting piece is arranged on the second shell, the second shell is provided with an organic meter screw, the main shaft is provided with a threaded hole matched with the organic meter screw, the second shell is provided with a pin, and the main shaft is provided with a pin hole matched with the pin.
