Introduction to the advantages and disadvantages of duckbill valve and its function, and the role of

Duckbill valve, that is, rubber sewage check valve, especially in the rainy season, the use of duckbill valve can effectively prevent floods, sewage, etc. backflow, and can also be drained at any time, and its main performance is to prevent the invasion of seawater and sediment, what else do you know about duckbill valves? How does a duckbill valve work? What are the advantages and disadvantages of duckbill valves?

I believe that many people are not clear, the following is a detailed introduction to the relevant situation of the duckbill valve, you can have a good understanding.

Duckbill valve introduction

Duckbill valve is commonly known as: rubber sewage check valve, also known as: back pressure flexible check valve, duckbill valve check valve, rubber check valve, rubber check valve, rubber slow closing check valve, etc.

According to the installation method, duckbill valves are divided into socket type, inlay type, built-in type, flange type, installation plate type, mortar or cement pipe type.

The main models are: XL-T, XL-F, XL-X. The valve does not have any moving components and is maintenance-free.

The valve can be used for straight pipes, flange pipes, cement pipes, FRP pipes, the valve is widely used in coasts, beaches, docks, reservoirs, municipal flood discharge, sewage, can be described as environmental protection green valve, the valve replaces the door, the gate, completely solve the problem that the door is easy to be blocked by sediment, silt, stones, vegetation, marine life.

role

The rubber duckbill valve can prevent flood and sewage backflow into street sewers and basements, avoid major losses, and prevent flood water from backing up into sewage treatment plants and drainage pumping stations when the water level rises; Prevents the spread of the odor of sewage or odorous fluids, and can be drained at any time; In the rainy season, it can prevent the flood of urban inland rivers from flooding from sewers to the streets; The quality is better than that of the door, and some defects such as the poor closure of the door are overcome.

Pros:

The duckbill valve has a low cost, and if the suitable rubber raw material is used, the service life exceeds that of the metal check valve, which is easy to install, flexible and diverse installation methods, and can be repaired.

1) Maintain a high jet velocity.

2) Preventing the intrusion of seawater and sediment is one of the main properties of the duckbill valve.

3) It is conducive to the flushing of the discharge pipe.

4) Under certain conditions, higher dilutions can be obtained.

5) No corrosion.

Cons:

The rubber body is not suitable for long-term open-air operation in the field, and the use of high-quality rubber cannot avoid aging.

1) Increase the cost of the project.

2) Increase diffuser head loss.

The above is the relevant introduction of the duckbill valve, everyone understands, right? In general, the duckbill valve is not only environmentally friendly, maintenance-free, convenient and flexible to install, but also it replaces the door, the gate, to solve the problem that it is easy to be blocked by sediment, vegetation, biology, etc., is widely used, especially on the coast, beach, dock, sewage equipment, etc. Of course, everything has its pros and cons, and there are also shortcomings of the duckbill valve, as long as we use it properly, it can actually serve us well.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only: Suzhou Neway Valve Co., Ltd., Shanghai Guanlong Valve Machinery, Shanghai Qizhong Valve Manufacturing, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

1. Sewage Sun Zhaoxin treatment: duckbill valve is mainly used for sewage treatment and discharge system, and the outlet of the water slag pump can lift the pumping station and submerged system.

2. The main feature of the duckbill valve is the elastic rubber structure, which does not need to be maintained, which can prevent backfilling, and the solid particle jam can still be tightly closed.

3. The duckbill valve can prevent floods and sewage from flowing into the sewers and basements of the streets, avoiding major losses. Prevent floodwater from flowing into sewage treatment plants and drainage pumping stations when the water level rises.

4. The duckbill valve is a dry quasi-water sealing device, which can also be used to channel the odor of the outdoor inspection well and solve the problem of sewage backing up into the room when the water level of the outdoor inspection well is high.

5. It is not easy to freeze when opening and closing, and the loss of water head is less when it is opened again; It can be customized for the special requirements of users with different working conditions and materials, and the important thing is that it has a long life.

6. The duckbill valve is convenient to open the group, has good sealing performance, can prevent odor back, and can meet the water (gas) sealing requirements of indoor drainage ditches and outdoor drainage pipes.

7. The duckbill valve can effectively prevent backflow and sediment generation in the process of discharging KT.

8. Better diffusion performance: the sewage discharged from the duckbill valve can reach the flow rate required for effective mixing, which is much smaller than the flow rate required for the same mixing of the circular pipeline.

9. Good diffusion performance: the jet speed is strong, the energy is large, and the duckbill-shaped discharge port has better diffusion than other standard round nozzles.

10. It has cushioning, sound-absorbing performance, maintenance-free and non-corrosion, etc.

The rubber duckbill valve can prevent flood and sewage backflow into street sewers and basements, avoid major losses, and prevent flood water from backing up into sewage treatment plants and drainage pumping stations when the water level rises; Prevents the spread of the odor of sewage or odorous fluids, and can be drained at any time; In the rainy season, it can prevent the flood of urban inland rivers from flooding from sewers to the streets; The quality is better than that of the door, and some defects such as the poor closure of the door are overcome.
