Description
Technical Field
The utility model relates to a manhole cover technical field, concretely relates to take shell ring longitudinal seam welded flange manhole cover of graphite composite pad.
Background
When a manhole cover is to be placed on the deck of an ocean-going vessel. It is generally close to the lower bulkhead and the manhole cover is arranged with its long axis parallel to the cabin, facilitating the installation of a vertical ladder below the manhole. For the convenience of access and ventilation, the larger tanks and the empty ones are provided with at least two manhole covers, which are remote from each other.
When the existing manhole cover is used on an ocean vessel, gaps often exist between the flange of the manhole cover and the flange cover due to loose connection, the phenomenon that the vessel is corroded due to seawater inflow is caused, and the use performance of the manhole cover is greatly influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take shell ring longitudinal seam welding flange manhole cover of graphite composite pad solves current manhole cover when using on ocean vessel, often appears connecting between the flange of manhole cover and the flange cover and closely there is the clearance, leads to the sea water to flow in and leads to boats and ships to receive the phenomenon of corruption, greatly influences the technical problem that this urgent solution of performance of manhole cover is treated.
In order to realize the above-mentioned purpose, the utility model provides a take shell ring longitudinal seam welding flange manhole cover of graphite composite pad, including shell ring, flange, blind flange, handle, flange journal ear, lid journal ear, pivot, graphite composite pad, the flange welding is in the top of shell ring, the blind flange is installed on the flange, the handle is located the blind flange, flange journal ear flange right side, lid journal ear connects on the blind flange right side, flange journal ear and lid journal ear are installed on the pivot, graphite composite pad is installed between flange and blind flange, graphite composite pad's thickness is 3-6 mm.
Preferably, the diameter of the cylindrical section is 500-590 mm.
Preferably, the thickness of the flange cover is 60 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the graphite composite pad is arranged between the flange and the flange cover, the thickness of the graphite composite pad is 3-6mm, the graphite composite pad with the thickness of 3-6mm has good corrosion resistance, high and low temperature resistance, good compression resilience and high strength, the flange and the flange cover can be precisely connected, the phenomenon that seawater flows in to cause the ship to be corroded is avoided, and the service performance of the manhole cover is improved.
