The sealing cover has the beneficial effects that the cooling water permeating into the sealing cover flows into the annular groove and is discharged into the liquid discharge hole through the annular groove, so that the phenomenon that the cooling water is insufficiently collected and discharged in the process of transferring the cooling water to the liquid discharge hole, and the cooling water remains in the sealing cover to cause equipment corrosion damage is avoided.

Further, the groove width of the annular groove is equal to the aperture of the liquid discharge hole.

Has the advantages that: the groove width of ring channel is less than the aperture of outage and then makes the utilization ratio of outage not high, if the groove width of ring channel is greater than the aperture of outage then makes the annular groove cooling water discharge in time to lead to the cooling water to spill over the ring channel, make the cooling water remain in sealed lid, cause equipment corrosion impaired.

Further, the longitudinal section of the annular groove communicated with the liquid discharge hole is trapezoidal, and the flaring faces the center of the placing hole.

Has the advantages that: the longitudinal section of the annular groove is increased, the volume of the annular groove is increased, and the discharge of cooling water is accelerated.

Further, the upper part of the sealing cover body is in a round table shape.

Has the advantages that: the cooling water on the outer surface of the sealing cover is provided with a drainage function, and the cooling water is drained through the inclined plane of the circular truncated cone, so that the cooling water is guided to the outer side of the sealing cover, and the amount of the cooling water permeating into the sealing cover is reduced.

Furthermore, the aperture of the liquid discharge hole is 1-2 CM.

Has the advantages that: the generated water mist is prevented from entering the inside of the liquid discharge hole from the outside of the liquid discharge hole, so that the amount of water mist infiltration is reduced.

Furthermore, the edges of the sealing covers are provided with chamfers.

Has the advantages that: the collision between the equipment is reduced, and the equipment is protected from being damaged, so that the service life of the equipment is prolonged.

Further, the liquid discharge hole is obliquely arranged towards the clamp ring, and the included angle between one side of the liquid discharge hole, which faces the clamp ring, and the central axis of the clamp ring is 70-90 degrees.

Has the advantages that: the further prevention water smoke that the outage that the slope set up enters into the outage to reduce the volume of water smoke in the sealed lid, guarantee that equipment can not receive the corruption damage.

Further, a protective layer is arranged on the outer surface of the sealing cover.

Has the advantages that: the sealing cover is not easy to rust, the replacement of the sealing cover by an enterprise is reduced, and the production and operation cost is increased.
