Product advantages

The socket-type duckbill valve has the advantages of cushioning, noise reduction, maintenance-free and corrosion-free. Its sealing performance, working performance in harsh environments and improving seawater purification performance are far superior to flapping doors, which solves the traditional flapping or butterfly check valve's poor operating conditions due to many mechanical failures, large leakage, valve seat wear, and parts deformation And technical problems of corrosion, noise, and need frequent maintenance and replacement. It is called a green valve. Socket-type duckbill valves are used in sewage systems, drainage systems, pump outlet lift pump stations and submerged aeration systems.

This product is a 100% elastic rubber structure. The clamp is made of stainless steel or wear-resistant and corrosion-resistant material. It is maintenance-free and prevents backfilling. The solid particle plug can still be closed tightly; it will not freeze during opening and closing; less head loss during opening; for customers Special requirements are customized, durable, and long service life, up to 50 years. Made of neoprene, nitrile rubber, fluorine rubber, etc.

Features

The socket-type duckbill valve can effectively prevent backflow, reverse irrigation and sediment formation. The difference from the outlet of the fixed tube in the past is that the jet velocity of the socket-type duckbill valve has a complex nonlinear relationship with the outlet flow. The flow rate of the sewage discharged from the socket-type duckbill valve to achieve effective mixing is much smaller than the flow rate required for the same mixing in round pipes. Various tests are performed on the flow characteristics of different valve ports. At the same time, these tests The data is analyzed and a general two-dimensional internal dynamics calculation formula is obtained. These test results show that the use of socket-type duck-bill valve can make the diffusion more stable, while the jet velocity is large and the energy is also large. The technology studied the mixing area of the jet flow at the duckbill valve port, and the results showed that the duckbill-shaped discharge port has a better diffusion effect than the standard round nozzle.
The special shape structure of the socket-type duckbill valve makes it convenient and quick to prevent backflow and reverse irrigation, saving time and effort. And because of its simple structure, there is almost no need for any maintenance work during use. Luoying socket-type duckbill valve is designed in accordance with national standards, good quality and good price, strong and durable, sufficient flexibility, with the function of forward inflow and reverse check.

Typical Case

Guodian Hami Dananhu Coal-fired Integrated Thermal Power Project # 2 Unit


Since this year, the eighth turbine-generator set manufactured by Shanghai Power Plant has joined the commercial operation. The coal power project Guodian Hami Energy Development Co., Ltd. 2.66 million kilowatt # 2 coal power project co-constructed with 800 kV UHV DC transmission project from South of Hami to Zhengzhou successfully passed the 168h trial operation at 21:30 on February 2, 2016. Performance indicators are good.
Guodian Hami Dananhu Coal-Electricity Integration Project with a capacity of 2.66 million kilowatts is located in Gobi Beach, south of Hami Nanhu Township. The project is constructed in accordance with the coal-electricity integrated pithead power station construction model. Simultaneously constructing flue gas dust removal, desulfurization, and denitration devices. It is a high-parameter, large-capacity, high-efficiency, highly water-saving, coal-electricity integrated pithead power plant that complies with national energy industry policies. It is the first ultra-supercritical air-cooling adopted in Xinjiang. Units, various consumption indicators and pollutant emission indicators are superior to conventional thermal power units.
Shanghai Luoying supplied more than 20 large-scale sewage check valves to the project this time, which can ensure the long-term safety of the pipeline operation. The special shape of the socket-type duckbill valve makes it convenient and quick to prevent backflow and backflow, saving time and effort. . And because of its simple structure, there is almost no need for any maintenance work during use. Luoying socket-type duckbill valve is designed in accordance with national standards, good quality and good price, strong and durable, sufficient flexibility, with the function of forward inflow and reverse check.
Hami, as the country's 10 million kilowatt-class coal power base, is the core output port and an important supporting power source for Xinjiang Power's delivery. With the 800 kV UHV DC transmission project from Hami South to Zhengzhou, it is the first UHV project of Xinjiang Power to East Upon completion and operation, the transmission capacity will reach 8 million kilowatts. At present, around the implementation of Xinjiang's power delivery strategy, Shanghai Electric has increased its participation and investment.
