Description

Technical Field

[0001] The invention relates to the technical field of ship steam, in particular to an improved main and accompanying steam pipe for a ship. Background Art

[0002] The steam system pipeline of the ship transports the steam generated by the boiler after reducing the pressure through the pressure reducing valve group. The steam is heated to provide high-temperature steam to various oil tanks, equipment, steam main and accompanying pipes and other places that need to be heated through the distribution station. After being cooled by low-temperature fresh water in the atmospheric condenser, it directly flows into the hot well below the atmospheric condenser. In addition, when the exhaust gas boiler generates excess steam (such as when the main engine is running), the excess steam will be automatically discharged to the atmospheric condenser through the excess steam valve and then returned to the hot well. When the boiler needs to be replenished with water, the feed water pump draws water from the hot well to form a closed cycle.

[0003] In the past, the main and accompanying steam pipes of fuel pipes, oil residue pipes, incinerator pipes and other piping systems (hereinafter referred to as piping systems) of ships (46000T series ships, 64000T series ships, 82000T series ships, etc.) were all made of Φ15*1.5 copper pipes, which had the following disadvantages: 1. Φ15*1.5 copper pipes are relatively thick and need to be completed by pipe bending machines and manual work. On-site bending and other construction are more difficult, and the copper pipe wall is severely deformed at some right-angle bends. 2. Since Φ15*1.5 copper pipes are relatively heavy and difficult to bend, they need to be cut several times on site to better fit the outer wall of the piping system, which requires more copper pipe ferrule joints. 3. Φ15*1.5 copper pipes are heavy, which increases the dead weight of the ship and also increases the procurement cost.

[0004] The advantage of "layer-by-layer distribution in the engine room" of the steam and condensate system piping was not effectively utilized, resulting in more "ineffective accompanying" main and accompanying pipes, resulting in more copper pipe consumption and insufficient steam utilization. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a main and accompanying steam pipe for improving ship steam

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The beneficial effects of the present invention are:

[0008] 1. By wrapping the main and accompanying pipes around the outer wall of the equipment pipe, the equipment pipe is fixed by using a fixing belt. The fixing belt is wrapped around the equipment pipe and then inserted into the inner wall of the fixing groove. At the same time, the positioning pin is inserted into the fixing hole to position the fixing belt. At this time, the main and accompanying pipes are positioned and fixed by inserting the connecting belt into the inner wall of the positioning groove, so as to facilitate the fixation of equipment pipes of different sizes;

[0009] 2. At the same time, Φ10*1 copper tubes are used for accompanying, which effectively realizes the accompanying heating function of the pipeline system. The "nameplate" and "operating instructions" produced at the same time have been praised by the ship's crew and have gained a good reputation. According to the comparison of the company's 82000 series ships, the purchase weight of copper tubes and the purchase quantity of ferrule joints save about half of the raw materials, and the material procurement cost is greatly reduced. The company uses Φ10*1 copper tubes for accompanying. The material is relatively fine, the construction difficulty is greatly reduced, and it is easy to bend. The construction efficiency is increased by about 50%, saving labor costs.
