Product advantages

The sleeve type duckbill valve has the advantages of buffering, silencing, maintenance free and corrosion-free. It is much better than flap valve in sealing performance, working performance in harsh environment and improving seawater purification performance. It solves the technical problems of traditional flap valve or butterfly check valve, such as poor operation condition, large leakage, valve seat wear, deformation and corrosion of parts, noise and frequent maintenance and replacement due to many mechanical failures. It's called green valve. The sleeve type duckbill valve is used in sewage system, discharge system, pump outlet, lifting pump station and submerged aeration system.

It is made of stainless steel and can be closed for a long time. It can be used for a long time. It can also be used for long time. Chloroprene rubber, butadiene rubber, fluororubber and other materials for production.

Product features

Different from the outlet of fixed circular pipe, the jet velocity and outlet flow rate of the sleeve type duckbill valve have a complex nonlinear relationship. The test shows that the velocity of the sewage discharged by the sleeve duckbill valve can reach the effective mixing speed, which is much smaller than that required by the same mixing in the circular pipe At the same time, the experimental data are analyzed and a general two-dimensional internal dynamic calculation formula is obtained. These experimental results show that the diffusion is more stable, the jet velocity is large and the energy is also large when using the sleeve type duckbill valve. The laser velocimetry technology is used to measure the mixing area of the duckbill valve The results show that the duck beak shaped nozzle has better diffusion effect than the standard round nozzle.
The special shape structure of the sleeve type duckbill valve makes it convenient and quick to prevent backflow and backflow, saving time and effort. And because of its simple structure, it almost does not need to spend any maintenance work in the use process. Luoying socket type duckbill valve is designed according to ~ standard, good quality, good price, strong and durable, elastic enough, with positive inflow, reverse check function

classic case

Guodian Hami Dananhu coal power integrated thermal power project No.2 Unit


Since the beginning of this year, the 8th steam turbine generator set manufactured by Shanghai generator works has been put into commercial operation. The 2.66 million KW ා 2 unit of Guodian Hami Energy Development Co., Ltd. successfully passed the 168 h trial operation at 21:30 on February 2, 2016, and all operation indexes of the generator set are good.
Guodian Hami Dananhu coal and power integration project is located in Gobi desert in the south of Nanhu Township, Hami. The project is constructed according to the construction mode of coal power integrated pithead power station. It adopts 660MW class water hydrogen hydrogen type steam turbine generator unit manufactured by Shanghai generator factory, and simultaneously constructs flue gas dust removal, desulfurization and denitrification devices. It is a high parameter, large capacity, high efficiency, and energy saving industrial policy The pithead power plant with high water-saving and coal electricity integration is the first ultra supercritical air-cooled unit adopted in Xinjiang. Its consumption index and pollutant emission index are better than those of conventional thermal power unit.
Shanghai Luoying has supplied more than 20 sets of large sewage check valves to the project, which can ensure the long-term stability of the pipeline operation. The special shape and structure of the sleeve type duckbill valve makes it convenient and quick to prevent backflow and backflow, saving time and effort. And because of its simple structure, it almost does not need to spend any maintenance work in the use process. Luoying socket type duckbill valve is designed according to ~ standard, good quality, good price, strong and durable, elastic enough, with positive inflow, reverse check function
Hami, as a 10 million kilowatt coal-fired power base, is the core output port and important support power supply for Xinjiang electric power transmission. With the completion and operation of the 800 kV HVDC transmission project from Hami south to Zhengzhou, the transmission capacity will reach 8 million kilowatts. At present, around the implementation of Xinjiang power transmission strategy, Shanghai Electric has increased its participation and investment.
