Gate valve structure: gate valve is the use of the gate and seat to control the opening and closing of the valve. Gate valve mainly has a valve body, valve seat, gate, valve stem, valve cover, stuffing box, packing gland, stem nut, hand wheel and other components. Depending on the change of the relative position between the gate and the valve seat, the channel size can be changed and the channel can be cut off. In order to make the gate valve close tightly, the mating surface of the gate plate and the valve seat are ground.
Dalian Shipai World's first electronically controlled marine diesel engine passed the appraisal
Recently, the world's first 7RTfLex58TB electronically controlled large-scale low-speed marine diesel engine, which was produced by Dalian Marine Diesel Engine Factory and patented by Wartsila Switzerland, passed the technical appraisal of municipal new products put into operation by the Municipal Economic Commission.
This product is the main engine of Dalian Shipbuilding Diesel Engine Co., Ltd. for the main product of Dalian Shipbuilding Industry Group Co., Ltd. with a capacity of 110,000 tons of large crude oil. After more than one year of sailing operation, it fully meets the requirements of the ship to the main engine. The product has the following characteristics: 1. The electronically controlled common rail system of the RT-Flex diesel engine has changed the traditional design structure, eliminating the need for fuel pumps, camshafts and transmission gears. 2. The main function of the diesel engine is realized by the electronic computer through the control, regulation and driving of the liquid-electric servo device. 3, RT-Flex diesel engine electronic control common rail system has good reliability; convenient handling performance; lower cylinder oil consumption rate, fuel consumption rate and emission control indicators; low speed stable operation target.
The electronically controlled marine diesel engine is one of the most advanced, widely used and popular models in the world, and has the world's advanced level. The successful development of this type of machine is of great significance to improving the level of major equipment manufacturing technology of China's ship mainframe and enhancing the competitiveness of the international market.
