Valve body material selection and features
As the core structure of the check valve, the valve body has multiple functions such as supporting the valve disc, sealing the medium and bearing the fluid pressure. Ningbo Baodi fully considers the key factors such as the corrosiveness of the medium, fluid pressure and working temperature in the selection of valve body materials, and adopts a variety of high-performance plastic materials, including rigid polyvinyl chloride (UPVC), chlorinated polyvinyl chloride (CPVC), reinforced polypropylene (FRPP), homopolymer polypropylene (PPH) and polyvinylidene fluoride (PVDF). These materials have the following significant advantages:
Excellent corrosion resistance: For the common corrosive media in the chemical, pharmaceutical and food industries, the plastic materials selected by Ningbo Baodi show excellent corrosion resistance, which significantly extends the service life of the check valve, thereby effectively reducing the cost of maintenance and replacement.
Good high temperature resistance: In high temperature working environment, Ningbo Baodi's check valve body uses high temperature resistant plastic materials such as PVDF to ensure that it can maintain stable physical and chemical properties under high temperature conditions, thereby ensuring the reliable operation of the check valve.
Lightweight and high strength: Compared with traditional metal materials, plastic materials have the advantages of low density and light weight, making Ningbo Baodi's check valves more convenient during installation and maintenance, significantly reducing the labor intensity of workers.
Easy to process and shape: The good plasticity of plastic materials enables them to be processed into valve bodies of various complex shapes through injection molding, extrusion and other processes, meeting the diverse design requirements of check valves.
Optimization and innovation of valve body structure design
In addition to the selection of materials, Ningbo Baodi has also made a number of optimizations and innovations in valve body structure design to improve the performance and reliability of check valves.
Streamlined design: In order to reduce fluid resistance and improve fluid passing efficiency, Ningbo Baodi's check valve body adopts a streamlined design. This design enables the fluid to flow smoothly through the valve body, reducing energy loss, thereby improving the overall efficiency of the system.
Rib structure: Ningbo Baodi has designed a rib structure inside the valve body to improve the strength and rigidity of the valve body. These ribs can effectively disperse the fluid pressure, prevent the valve body from deforming or rupturing under high pressure, and ensure the stable operation of the check valve.
Sealing structure design: The sealing performance of the check valve is one of the important indicators for evaluating its quality. Ningbo Baodi adopts a design scheme that combines elastic sealing materials (such as rubber, tetrafluoroethylene, etc.) with hard valve seats in the sealing structure design of the valve body. This design not only ensures the reliability of the seal, but also facilitates the maintenance and replacement of seals.
Convenient installation and maintenance: Ningbo Baodi's check valve body design fully considers the convenience of installation and maintenance. For example, the valve body is equipped with flange connection structures and threaded connection structures that are easy to disassemble and clean. At the same time, the internal structure of the valve body is reasonably designed, which is convenient for workers to conduct internal inspections and repairs, and improves the overall use efficiency.
