Product Introduction
Rubber Duckbill Check Valves are a professional pipeline connection valve characterized by a clamp type connection method, which can quickly, conveniently, and safely connect pipelines. This type of valve is commonly used in various fluid pipeline systems, such as water treatment, chemical industry, construction, water supply, natural gas, and other fields.
Rubber Duckbill Check Valves have a simple and beautiful appearance, compact structure, easy installation, and simple operation. Its advantage is that no tools are required during installation, and the valve can be easily fixed on the pipeline by gently twisting it. This type of valve also has strong corrosion resistance and high temperature resistance, allowing it to work reliably in various harsh working environments.
Rubber Duckbill Check Valves have a wide range of applications, especially playing an important role in pipeline installation and maintenance. Its fast, safe, and reliable features have been favored by a large number of users.
Rubber Duckbill Check Valves are a very practical pipeline valve with advantages such as compact structure, easy installation, simple operation, corrosion resistance, and high temperature resistance. We can see that clamp type duckbill valves have been widely used in modern industry and are also promoting industrial development.
The operation instructions of Check valve with Laryngeal hoops
1,The material of the Check valve is rubber. When loading and unloading, transportation and installation, it is necessary to use the cloth lifting belt. The surface of the Check valve is forbidden to be scratched by edge tool.
2,When installing the Check valve, attention should be paid that the nozzle line of the Check valve is perpendicular to the ground .
3,The installation position of the Check valve with Laryngeal hoops is designed to sleeve and insert the connecting pipe directly. The sleeve and the inner wall of the sleeve can be sealed with water glue and the laryngeal hoops should be metal. Gasket should be added between the holes of the laryngeal hoops to fastening the screw. To prevent the Check valve from falling off for a long time using, it is allow to drilled through the body of Check valve and the wall of pipe using the electric drill according to the holes on the laryngeal hoops and using the screw to tighten the Check valve and laryngeal hoops by penetrating them.
4,When the back-pressure of Check valve is large, it is necessary to install bracket inside Check valve to resist back-pressure and protect duckbill valve from being damaged.
5,When the weight of Check valve is heavy because of the large diameter and a large number of water and the impact force of water when the Check valve working, a supporting rod should be added to lift the Check valve stably for a long time(The valve body has a lifting ring, which can not use to move the Check valve!)
6,After the installation of Check valve, the water outlet must be checked to insure the availability of water outlet.
7,During the trial running of Check valve, or when the pump is stopped during operation, there shall be no back-pressure inside the pipe where duckbill valve is installed.
8,The Check valve should be far away from heat source. It is forbidden to connect with engine oil and strong radiation light. It should be covered when it is used outdoors.
9,Regularly check the supporting and lifting devices of Check valve, is an important way to keep the good usability of Check valve. As to the Check valve without bracket or hoisting, related devices must be installed.
10,Regularly check the decontamination grid of Check valve front-end in order to prevent the performance degradation of decontamination grid, which will cause excessive floating or sediment in Check valve and affect the service performance.
