"Smart" valve opened to the high-end domestic marine market – valves,
As blood vessels in the arterial, venous, ships of various sizes within the pipeline Valve Control of the boat body, "blood" flows. Recently, reporters from the seventh shipbuilding industry? 4 Institute was informed that a ship made of advanced Valve Doors by remote control system in the birth and has been run successfully for several months on board ever since the end of our large ships is expected to use only imported equipment history.
"Smart" valve opened to high-end domestic market for marine
Large ship thousands of valves, of which more than 100 valve job on board the most dangerous and dirtiest places, such as the cargo hold loaded with crude oil, ballast water into the ballast cabin?? This requires valve remote control system to precisely control their switch.
As work full of crude oil, refined oil cargo hold, can not have the slightest spark of a star, Guer the most common sensor signals by wire transfer in these valves, the entirely useless. This is more than one hundred valves, located in a large ship, no less than 100 meters away from each other, the valve can be far more than 300 meters from the control center. Therefore, the control they have become a cutting-edge technology, equipment manufacturers have long been the monopoly of foreign ships.
To be opened to the high-end market, beginning in 2005, China Shipbuilding Heavy Industry Group 7? 4, April 2 Liu Chang, Dalian Marine Valve Factory and other jointly launched a large-scale Valve Remote Control System. They developed with independent intellectual property rights valve remote control systems?? Only by hydraulic control channels, while achieving a valve switch control and valve opening time monitoring.
Earlier this year, one called "Hamming foreign" of 120,000 tons to transform the old oil tanker, this made valve remote control systems to take this opportunity to debut a big ship. Loading operation so far, the system is very stable. This allows the project leader, seven? 4 researcher Yu Shao very happy because this is our country be opened to high-end automation systems for large ships loading and unloading door market, made a solid first step.
A large tanker would cost about one-third of automation systems for ship loading and unloading. Automation system as one of the three ships, in addition to valve remote control systems, handling automation including Pump Pu system, inert gas systems, liquid level telemetry system, the monitoring system for oil discharge a dozen subsystems. 2003 years ago in this area of high-end market is almost a blank.
Although the entire boat valve remote control system in the share of cost is not high, it is critical: to master the core technology of the system, other systems can be analogy. Shao Yu said that this made valve remote control systems are now only considered as initial scale, R & D team will also further improve the design and development of a series of products, to apply to more ship. Meanwhile, relevant state ministries and local governments with the support of a project called "Liquid Cargo Handling System Integration Technology" of the research project is brewing, if implemented, will officially sounded the board in China to the loading and unloading of large ships to enter the automated system horn.
