Valve replacement device for shipbuilding

Abstract

The invention discloses a valve replacement device for shipbuilding. The device is used for temporarily replacing a valve in a pipeline system and comprises an adjustable screw, connecting plates andlocknuts; the adjustable screw is cylindrical; threads are distributed at the two ends of the adjustable screw; a screw hole is formed in the middle of each connecting plate; the two ends of the adjustable screw are in threaded connection with the connecting plates correspondingly; the two ends of the adjustable screw are in threaded connection with the locknuts correspondingly; and the locknuts abut against the connecting plates. The valve replacement device has the beneficial effects that the valve replacement device has the advantage of multiple replacement varieties, has good practicability, economy and popularization feasibility, and is broad in market prospect.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a valve part replacement device for shipbuilding. Background technique [0002] Ship outfitting engineering has a series of characteristics such as many varieties, many processes, wide cooperation and long cycle. Among them, pipe manufacturing, installation and debugging have the largest workload, the longest period and the widest scope. Therefore, the transformation of pipe and outfitting technology is an important aspect of the transformation of outfitting technology. At present, the domestic shipbuilding industry has abandoned the previous extensive traditional shipbuilding model and replaced it with a lean shipbuilding model that combines production design and pallet management technology, and integrates shell, outfitting and coating. The pipe outfitting method is divided into four stages: unit assembly, section pre-assembly, general section assembly and ship outfitt...

Problems solved by technology

Due to the impact of supporting equipment, the pre-outfitting operation site often encounters the dilemma of "no rice to cook", which brings a lot of inconvenience to the pre-outfitting operation: 1. When pre-outfitting in sections, the valves on the pipeline often Due to factors such as lack of delivery or loss, it is difficult to install and locate pipes, such as pipes arranged longitudinally on the deck of the cargo hold, ballast pipes in the double-layer low pipe lane, expansion joints of bilge pipes, remote control butterfly valves, etc.; 2. Sometimes the valve accessories installed close to the bulkhead of the oil-water tank affect the integrity of the pre-outfitting operation due to untimely arrival, such as quick-closing valves, inspectors, filters, etc.; Affected or equipment unpacking time is not timely, it will also cause the installation or school management of regional pipes (such as engine room oil-water pumps, oil-water separators, water generators, ballast water treatment devices, etc.)

In the case of the above situation, the common way is to find a valve with the same length and the same specification as a replacement according to the valve accessories sample data. If it is a series ship, it usually needs to be demolished from other ships, which is time-consuming and laborious, or use pipes and flanges to manufacture a valve. Temporary substitutes, although they can solve the problem, are often thrown away as waste when they are used up here. If there are many valve parts missing and there are many types, this method is uneconomical and wastes manpower and material resources. a proven solution
