Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the figure, the expansion type release plug for the ship comprises a shifting block 1, a plug seat 4 and a plug bolt penetrating through the plug seat, wherein the plug seat is welded and fixed at the low position of an oil retaining fence on a ship deck, the shifting block 1 is connected with an expansion shaft 2 on the plug bolt through a bolt 7 and a nut 8, after the shifting block 1 is rotated by 90 degrees by using a spanner, the distance between a limiting block 3 and a backing plate 5 is reduced, and a sealing block 9 clamped between the shifting block and the backing plate is tightly attached to an inner hole of the plug seat 4 after being subjected to extension deformation caused by axial pressure, so that the sealing effect is realized; 90 reverse rotation displacement piece 1, stopper 3 and backing plate 5 interval grow, and rubber seal 9 extends to warp and disappears, keeps off the oil water mixture in the oil rail and flows out along the clearance between seal 9 and the stopper seat 4.
One side of the shifting block 1 is provided with a through hole 1.1 for inserting a wrench to twist the shifting block 1 to turn; the other side is equipped with and is used for bolt 7, nut 8 to connect the lug of inflation axle 2, is equipped with the bolt through-hole with the axle center on the lug, and the interval of bolt through-hole moment stopper 3 is less than the interval of the piece both sides that shift.
Expansion shaft 2 one side is equipped with the rings of being connected with the piece 1 that shifts, and the opposite side is equipped with the screw thread and is used for lock nut 6 to be connected, installs stopper 3, sealed piece 9 and backing plate 5 between rings and the lock nut 6, alternates in stopper seat 4.
The limiting block 3 is in a ring shape, and a stepped shaft shoulder is arranged outside the limiting block and is limited by the side face of the plug seat 4.
The nut 8 of the displacement block 1 connected with the expansion shaft bolt 7 is connected with a small marine chain 10 which is used as an anti-static grounding band to eliminate static electricity and prevent the loss of a plug detached from drainage.
The sealing block 9 is a cylinder with a concentric through hole and is made of chloroprene rubber.
The plug seat 4 is provided with an inner hole penetrating plug, the inner hole is in clearance fit with the sealing block 9 and the backing plate 5, and the plug seat 4 is made of 0Cr19Ni9 or 0Cr18Ni9 stainless steel.
The working principle is as follows:
the interval of the bolt through-hole moment stopper on the shifting block is smaller than the interval of the two sides of the shifting block, after the shifting block is rotated by 90 degrees by using a wrench, the interval between the stopper and the backing plate is reduced, and the rubber sealing block between the stopper and the backing plate is tightly attached to the inner hole of the plug seat after being extended and deformed by axial pressure, so that the sealing effect is realized.
When the profit in the rail needs to be released, 90 opposite direction rotation displacement pieces, stopper and backing plate interval grow, and rubber seal piece extension deformation disappears, and the oil-water mixture flows along the clearance between rubber seal piece and the stopper seat.
When the rubber sealing block is aged and needs to be replaced, the rubber sealing block can be replaced only by opening the shifting block, integrally drawing out the plug along the inner hole of the plug seat and dismounting the locking nut.
The working process is as follows:
1) the periphery of the plug seat is welded with an oil baffle fence on a ship deck, and the fillet weld joint sealing is required to be realized;
2) assembling the plug: after the limiting block, the sealing block and the base plate are sleeved by the expansion shaft, the sealing block is tightly attached to the limiting block and the base plate by using the locking nut, and the sealing block is not extended and deformed;
3) the plug is inserted into the inner hole of the plug seat, and the stepped shaft shoulder surface of the limiting block is tightly attached to the outer wall of the plug seat; connecting the expansion shaft and the displacement block together by adopting a bolt and a nut;
4) a spanner is used for rotating the displacement block by 90 degrees, so that the sealing block is ensured to be tightly attached to the inner hole of the plug seat, and the sealing function of the expansion type discharging plug is realized;
5) the wrench is used for reversely rotating the shifting block by 90 degrees, so that a gap is generated between the sealing block and the inner hole of the plug seat, and the releasing function of the expansion type release plug is realized.
The method is characterized in that:
because the interval of the bolt through-hole moment stopper on the piece that shifts is less than the interval of the piece both sides that shift, after using the spanner to shift the piece and rotate 90, stopper and backing plate interval reduce, and the sealed piece of rubber is receiving axial pressure to produce the extension and is out of shape the back and closely laminate with the stopper seat hole, so, simple structure, it is sealed reliable, no corrosion damage, long service life.
Because the reverse rotation transposition piece 90, just can produce the clearance between sealed piece and the stopper seat hole, so, can carry out the work of releasing fast, simultaneously, can take out the cock, loosen lock nut, open the backing plate, change sealed piece realizes sealed piece's maintenance.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
