The model utility content
At the existing above-mentioned deficiency of existing lubricated sealing device of oil, technical problem to be solved in the utility model is that a kind of high-pressure resistance oil lubricating seal device of ship will be provided, it can improve the ability of the anti-seawater pressure of lubricated sealing device of oil, and eliminates the possibility of oil leak to the ocean.
In order to solve the problems of the technologies described above, the scheme of the utility model technical solution problem is: a kind of high-pressure resistance oil lubricating seal device of ship, comprise sealing seat, lip-type packing, the head of described lip-type packing is by described sealing seat clamping and fixing, the basil one side is provided with plane radially behind the lip of described lip-type packing, the basil one side also is provided with and the corresponding dunnage in described plane after the described lip-type packing, and this dunnage is fixedly connected on the described sealing seat.
After adopting such scheme, owing to the plane that is provided with at lip-type packing lip rear side radially, and be fixed on the sealing seat and to be positioned at the dunnage of lip-type packing rear side corresponding with this plane, thereby when seawater pressure excessive, when moving after making lip-type packing axial, dunnage can axially prop up the plane of lip rear side, thereby the lip of supporting lip-type packing, again since the waist of lip-type packing between head and lip, thereby dunnage also can support the corner of lip-type packing posterior lumbar, when real ship assembles, dunnage contacts with the corner of lip-type packing posterior lumbar, and the gap that 1～3mm is arranged between the plane of lip rear side, side shaft is excessive to displacement backward can either to stop lip-type packing like this, improve the performance of lubricated sealing device of oil sea water resistance pressure, do not influence lip-type packing waist and lip moving radially among a small circle again, make the followability of lip-type packing unaffected substantially; Simultaneously, because lip-type packing is subjected to the dunnage supporting, can resist seawater pressure preferably, thereby can reduce oil pressure in the oil pocket, and the stability of oil pressure and the requirement of following the tracks of the sensitivity of seawater pressure descended to some extent, thereby can save the cost of oil pressure control aspect, and oil pressure descends and to be not easy to cause lubricant oil to leak into the sea from the lip of lip-type packing, can reduce pollution the ocean.
The plane radially of the basil one side is the plane of annular behind the lip-type packing lip, and dunnage can be along circumferentially lip-type packing being supported.
Dunnage is single parts, adopts boss structure and sealed socket sleeve to be connected together, and uses the bolt tightening.
Dunnage and sealing seat are merged into an integral body during fabrication.
