Pressure resistance requirements for different types of marine valves
Marine globe valve
Ships are subjected to high water pressure during navigation, and marine shut-off valves need to have sufficient pressure resistance to ensure that the valves are not damaged due to excessive water pressure. The fully performance ultra lightweight regulating valve body structure of marine stainless steel pneumatic globe valve is a single piece integrated structure, which improves the structural integrity of the pressure boundary and enhances the pressure resistance strength. The low pressure adopts a forged structure, further improving the pressure resistance strength of the valve body, with a pressure resistance strength of over 32MPa.
Stainless steel valves for industrial ships
The pressure of the medium in the pipeline and container during the entire production process generally does not exceed 1.6 MPa. The pressure resistance requirements for valves used for medium control in production are also based on this standard, and relatively little consideration is given to some complex high-pressure situations.
Related standards and tests for pressure resistance performance
Standard regulations
The pressure test standards for valves are usually specified by national or industry standards, which include testing methods, conditions, standard values, and other content. The theoretical framework for valve pressure test standards and gas corrosion resistance testing is based on principles of engineering mechanics and materials science.
test method
In the pressure resistance test, a series of testing methods are used to evaluate the pressure resistance performance of the valve, including static pressure test, leakage test, impact test, etc. These tests can ensure that the valve will not leak or fail under normal working pressure, thereby ensuring the normal operation of the system.
The correlation between pressure resistance and other performance indicators
Association with sealing
The sealing performance of marine globe valves is directly related to the safe operation of ship systems, and good pressure resistance helps ensure that valves can maintain good sealing under high pressure conditions, effectively preventing fluid leakage.
The correlation between reliability and durability
The pressure resistance performance is an important component of the reliability and durability design of marine valves. By improving the pressure resistance of valves, the structural strength of key components can be enhanced, and the corrosion resistance, vibration resistance, and impact resistance of valves can be improved, thereby improving the reliability and durability of marine valves.
