Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a ferrule-type port fitting for allowing ship pipelines to pass continuously through ship bulkheads. Background Technology

[0002] Marine piping is used to transport fluids such as ballast water, fire-fighting water, cooling water, fresh water, fuel oil, lubricating oil, and air required by the ship. Marine piping is a crucial aspect of ship design and construction. Because seawater has a strong corrosive effect on steel pipes, marine piping used to transport seawater typically requires overall galvanizing of both the inner and outer walls. When marine piping passes through decks or bulkheads, it must be connected using pipe-to-buoyancy fittings.

[0003] Currently, the commonly used bulkhead through-hole components on ships include conventional flange through-hole components and sleeve through-hole components. Both of these components are fixed to the bulkhead by welding their web plates, and then the ship's pipelines are welded to the web plates. Due to the uneven gap between the web plates and the bulkhead, the welding quality is difficult to guarantee. There is also a great deal of difficulty in welding the ship's pipelines to the web plates. In addition, conventional through-hole components cannot allow pipelines to pass through watertight bulkheads. Summary of the Invention

[0004] In view of this, the present invention provides a ferrule-type port fitting for allowing ship pipelines to pass continuously through ship bulkheads, thereby solving the problems existing in the background art.

[0005] A ferrule-type port clearance fitting for allowing ship pipelines to continuously pass through ship bulkheads includes a port clearance fitting body, a retaining ring, and a locking sleeve. The port clearance fitting body is disposed within a port clearance hole on the bulkhead, and a locking sleeve is threadedly fixed to both ends of the port clearance fitting body on both sides of the bulkhead. A first through hole is formed through the port clearance fitting body along its length. A second through hole is formed through the center of the locking sleeve. The second through hole is connected to the first through hole to form a channel for allowing ship pipelines to continuously pass through from one side of the bulkhead to the other side of the bulkhead. The retaining ring is disposed within the gap formed between the port clearance fitting body, the locking sleeve, and the ship pipelines.

[0006] Preferably, the first through hole is composed of a cylindrical hole segment and tapered hole segments connected to both ends of the cylindrical hole segment. The diameter of the cylindrical hole segment is equal to the diameter of the second through hole, and the diameter of the second through hole is equal to the outer diameter of the ship's pipeline.

[0007] Preferably, the tapered surface of the tapered hole section is inclined downward toward the center of the cabin body.

[0008] Preferably, the retaining ring includes a boss-shaped ring body and a tapered ring body extending from the top of the boss-shaped ring body, wherein the inclination direction of the tapered surface of the tapered ring body is the same as the inclination direction of the tapered surface of the tapered hole section of the first through hole.

[0009] Preferably, the inclination angle of the conical surface of the conical ring is smaller than the inclination angle of the conical surface of the conical hole section of the first through hole.

[0010] Preferably, the body of the passage component is welded and fixed to the bulkhead.

[0011] Preferably, the locking sleeve is a locking nut.

[0012] The beneficial effects of this utility model are:

[0013] 1. This application welds and fixes the body of the through-hole component in the bulkhead, and then fixes and locks the two sections of the through-hole component body with threads, so that the ship's pipeline can continuously pass through from one side of the bulkhead to the other side. A retaining ring is installed in the gap formed between the through-hole component body, the locking sleeve and the ship's pipeline for sealing. The pipeline can pass through the watertight bulkhead without disconnecting the pipeline on both sides of the watertight bulkhead, which ensures the continuity of the pipeline. Moreover, only the through-hole component body needs to be welded and fixed to the bulkhead, which effectively reduces the welding difficulty and ensures the welding quality.

[0014] 2. The ferrule through-body fitting of this application has a simple structure and is easy to install and use. Under the premise of ensuring the function of the ferrule, its internal structure is optimized to meet the design requirements of relevant specifications. Without increasing any additional costs, it solves the problem that the pipeline cannot pass through the watertight bulkhead continuously. Attached Figure Description

[0025] To better understand the technical solution of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.

[0026] This utility model provides a ferrule-type port clearance component for allowing ship pipelines to pass continuously through ship bulkheads, comprising a port clearance component body 1, a retaining ring 2, and a locking outer sleeve 3.

[0027] The through-hole body 1 is installed in the through-hole on the bulkhead 4, and its outer surfaces at both ends on both sides of the bulkhead are threaded. The through-hole body 1 is welded and fixed to the bulkhead 4. A first through hole 5 is provided through the through-hole body 1 along its length. The first through hole 5 consists of a cylindrical hole section and tapered hole sections connected to both ends of the cylindrical hole section. The tapered surface of the tapered hole section is inclined downward toward the center of the through-hole body 1. The diameter of the cylindrical hole section is equal to the outer diameter of the ship's pipeline 9.

[0028] The locking sleeve 3 is threadedly fixed to both ends of the through-hole body 1. A second through hole 6 is provided through the center of the bottom of the locking sleeve 3, and the outer diameter of the second through hole 6 is equal to that of the ship's pipeline 9. When the locking sleeve 3 is screwed onto the end of the through-hole body 1, the second through hole 6 of the locking sleeve 3 is connected to the first through hole 5 of the through-hole body 1, thereby forming a channel for the ship's pipeline 9 to continuously pass through from one side of the bulkhead 4 to the other side of the bulkhead 4.

[0029] The retaining ring 2 is disposed in the gap formed between the through-hole body 1, the locking sleeve 3, and the ship's pipeline 9, and serves as a seal. The retaining ring 2 includes a boss-shaped ring body 7 and a tapered ring body 8 extending from the top of the boss-shaped ring body 7. The inclination direction of the tapered surface of the tapered ring body 8 is the same as the inclination direction of the tapered surface of the tapered section of the first through hole 5, and the inclination angle of the tapered surface of the tapered ring body 8 is smaller than the inclination angle of the tapered surface of the tapered section of the first through hole 5.

[0030] In this embodiment, the locking sleeve 3 is a locking nut, and the bulkhead 4 is a watertight bulkhead.

[0031] When installing the above-mentioned ferrule-type through-hole fitting, first place the through-hole fitting body 1 in the through-hole on the bulkhead 4 and weld the through-hole fitting body 1 to the bulkhead 4; then, fix a set of retaining rings 2 and locking sleeves 3 to one end of the through-hole fitting body 1 (first place the retaining rings 2 inside the locking sleeves 3, and then screw the locking sleeves 3 to one end of the through-hole fitting body 1); then, pass the ship's pipeline 9 through the locking sleeves 3 and the through-hole fitting body 1; finally, put another set of retaining rings 2 and locking sleeves 3 on the other end of the through-hole fitting body 1, and after the ship's pipeline 9 is positioned, tighten the locking sleeves 3.

[0032] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
