Product Characteristics

Clamp type duckbill valve can effectively prevent backflow backflow and sediment generation, with the previous fixed round pipe outlet is different: the clamp type duckbill valve jet velocity and the outlet flow rate is a complex non-linear relationship, the test shows that the clamp type duckbill valve discharge sewage to achieve an effective mixing of the flow rate required, far more than the circular pipe the same mixing required flow rate is much smaller, the flow characteristics of the different valve ports to carry out a variety of tests, while analyzing the data from these tests to derive a general two-dimensional internal dynamics formula, the results of these tests show that the use of a clamped duckbill shaped valve results in a more stable diffusion, as well as a high jet velocity and energy, the use of laser velocimetry to investigate the vicinity of the mixing region of the jet stream at the duckbill port was studied, and the results showed that the duckbill shape of the discharge port has a much better than the standard circular nozzle Diffusion.

The special shape of the clamped duckbill valve makes it easy and quick to prevent backflow and irrigation, saving time and labor. Because of their simple structure, they require little maintenance during use. The clamp type duckbill valve is designed in accordance with ~ standard, good quality and price, sturdy and durable, with sufficient elasticity, with the function of positive inflow, reverse reverse stop.1 Rubber sewage check valve has a novel structural design, which can realize that positive sewage can be easily discharged, and the reverse sewage can be realized as an effective stop.

2 simple structure, easy to install, the use is also very convenient, almost no need for any maintenance process!

3 The product is made of rubber, long service life and stable operation.

4 clamp type connection is quick and easy to install, reducing the difficulty of construction.

Gongyi Dongli and Hami City North City Flood Control Project Cooperation Site

On the same day, at the construction site of Hami City Shichengzi Drainage Youth Drainage, the construction personnel used excavator to pass the water-discharging culvert pipe from the bottom of Youth Drainage.

It is understood that the north of the city flood control construction project is the key water conservancy project in Hami City this year, the project plans to invest 12 million yuan, the project flood control standard for 20 years. The project can be Shichengzi river channel discharge flood water through the diversion to reduce the peak flow, through the new diversion, levees and sectional diversion gates and other buildings, combined with the downstream of the constructed levees and flood control channel will be flood water into the downstream of the north side of the 312 National Highway, a number of gravel fish scale pits for stagnation, to be stabilized after the flood precipitation and then the use of diversion pipelines and pumps and pumping facilities will be the fish scale pits of the water storage were discharged into the flood discharge channel, the storage of water through the The river flows through Hami City to draw the South Zengshui, People's Park, Guangdong Road South Fitness Plaza and so on, and very much later converge into the Garden Township Reservoir.

Gongyi Dongli supply the clamp type duckbill valve can effectively prevent backflow backflow and sediment generation, with the previous fixed round pipe outlet is different: the clamp type duckbill valve jet velocity and the outlet flow rate is a complex non-linear relationship, the test shows that the clamp type duckbill valve discharge sewage to achieve the effective mixing of the flow rate required, far more than the same mixing of the circular pipeline the flow rate required for the smaller!

According to the project leader, Hami City, water conservancy planning, surveying and design team vice captain Liu Haitao introduction, youth canal bear Hami soldiers land agricultural irrigation important task, in order not to affect the spring irrigation water, Hami City, in advance to start the youth canal section of the water relief pipe across the work, to ensure that the channel in the spring irrigation period of normal operation.

After the completion of the project will guard against the mountainous areas of snowmelt, heavy rainfall, Gobi torrential floods and reservoir discharge floods, to protect the lives and property of the people of Hami city and the surrounding suburban townships, regiments, and supplement the downstream ecological water.
