Claims

[Scope of utility model registration request]

An annular groove is formed approximately in the radial direction of the sliding surface of the fixed side sealing ring of an external temperature mechanical seal installed in various horizontal devices, and the sliding surface is connected to the outer peripheral sliding surface and the inner peripheral surface. Divided into two on the side sliding surface,
A required number of cooling water injection holes are formed at the bottom of the annular groove, and a required number of notched grooves for cooling water outflow are formed on the outer circumferential sliding surface, so that the cooling water is introduced into the cooling water injection holes. A mechanical seal characterized in that conduction is established from the annular groove into the annular groove and further from the annular groove to the outside via the notch groove.
