Marine Cast Steel Seawater Sdnr Valves Cb/t3197 - 95 B/bs Angle Type With Ccs Classification Society Certificate
1. Product Overview
The marine cast steel seawater SDNR valve CB/T3197-95 B/BS angle type is a valve specially designed for ships. It is made of cast steel, featuring high strength and good corrosion resistance. It is particularly suitable for controlling corrosive media such as seawater. This valve combines the functions of a stop valve and a check valve, effectively controlling the flow direction of the fluid and preventing the backflow of the medium.
2. Model and Standard
Model: CB/T3197-95 B/BS angle type
Standard: It complies with the CB/T3197-95 standard, which sets strict requirements for aspects such as the material properties, mechanical strength, and sealing performance of the valve.
3. Structural Features
Angle design: The valve adopts an angle structure. The fluid changes direction inside the valve, reducing the space occupied by the pipeline system and making it more convenient to install the valve in limited spaces such as on ships.
Cast steel material: Key components such as the valve body and valve cover are made of cast steel, with high strength and corrosion resistance. They can withstand various pressures and vibrations during the ship's operation, ensuring the stable operation of the valve.
Sealing performance: The valve uses high-quality sealing materials. After precision machining and strict testing, it can effectively prevent the leakage of the medium in the closed state, ensuring the safe operation of the ship's pipeline system.
Check function: The valve is equipped with a built - in check mechanism, which can automatically prevent the backflow of the medium and protect the safe operation of the ship's pipeline system.
4. Technical Parameters
Nominal pressure: It depends on the specific model but generally can meet the pressure requirements of the ship's pipeline system.
Nominal diameter: It depends on the specific model and is suitable for a certain range of diameter requirements.
Connection method: Flange connection, in line with relevant standard regulations, facilitating connection and disassembly with the pipeline system.
Operating temperature: It is suitable for a certain range of operating temperatures, specifically depending on the selection of the valve material and sealing material.
5. Application Fields
This valve is widely used in the ship's seawater system, cooling system, fuel system, and drainage system, etc., to control the flow direction and pressure of the fluid, ensuring the normal operation and safety of the ship.
VI. Installation and Maintenance
Installation: Before installation, check whether the appearance and internal parts of the valve are intact to ensure the normal function of the valve. The valve should be installed on horizontal or vertical pipelines, and ensure that the flow direction of the valve is consistent with the flow direction of the medium. Use sealing gaskets at the flange connections to ensure the sealing performance of the connections.
Maintenance: Regularly inspect and maintain the valve, such as cleaning and lubricating, to extend the service life of the valve. During the inspection process, pay special attention to whether the sealing performance and check function of the valve are normal. If any abnormal situation is found, handle and repair it in time.
