Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a detachable watertight penetration component. Background Technology

[0002] When a penetrating component passes through a watertight bulkhead, a watertight penetrating device is needed to be installed between the penetrating component and the watertight bulkhead to achieve a seal between them. Conventional penetrating components are simply welded parts that cannot be disassembled, and therefore cannot meet the requirements of practical use. Summary of the Invention

[0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a detachable watertight penetration component.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A detachable watertight penetration component is disposed between a penetration member and a watertight bulkhead. The watertight bulkhead has a penetration hole through which the penetration member passes. It includes a cover plate, a base, and a sealing ring. The cover plate, base, and sealing ring are all annular. The base is fixed to the watertight bulkhead, and the penetration hole is located within the area enclosed by the base on the watertight bulkhead. The sealing ring is disposed on the base, and the cover plate is disposed on the sealing ring. The cover plate and the base are connected by fasteners. The fasteners pass through the sealing ring. The cover plate has a through hole for the penetration member to pass through. A stuffing box is disposed within the through hole to achieve a seal between the cover plate and the penetration member.

[0006] Furthermore, the base and the watertight bulkhead are sealed together.

[0007] Furthermore, the base and the watertight bulkhead are connected by welding, and the welds between the base and the watertight bulkhead are distributed along the circumference of the base.

[0008] Furthermore, the sealing ring is a rubber sealing ring.

[0009] Furthermore, there are multiple fasteners, which are distributed circumferentially along the cover plate.

[0010] Furthermore, the fastener is a bolt.

[0011] Furthermore, the cover plate comprises two plate-like members; the two plate-like members form a ring.

[0012] Furthermore, a strip-shaped reinforcing member is fixed at the bottom of the cover plate; the strip-shaped reinforcing member is located between the cover plate and the watertight bulkhead.

[0013] Furthermore, there are multiple strip-shaped reinforcing members, which are distributed radially along the cover plate.

[0014] Furthermore, the inner wall of the through hole is provided with an annular reinforcing member, and the strip-shaped reinforcing member is connected to the annular reinforcing member.

[0015] The beneficial effects of this invention are as follows: The detachable watertight penetration member of this invention is located between the penetration member and the watertight bulkhead. Through the cooperation of the base, sealing ring, cover plate, and stuffing box, a good seal is achieved between the penetration member and the watertight bulkhead. When disassembly is required, the bolts are loosened, and the cover plate, sealing ring, and stuffing box can all be detached, thus achieving quick disassembly. When reinstallation is required, the sealing ring and cover plate are installed on the base, the stuffing box is installed between the cover plate and the penetration member, and the bolts are tightened, thus achieving quick installation of the watertight penetration member. The detachable watertight penetration member of this invention has the advantages of convenient installation and disassembly, and strong watertightness. Attached Figure Description
