Valve technology harmful phenomena in the operation of control valve

First of all, the harmful phenomenon is serious noise, which will affect the health of employees and the working environment. Noise is a symptom from the inside of the valve, which usually affects the durability of the equipment and even damages the equipment. The generation principle of valve noise can be divided into the following categories: mechanical, aerodynamic and hydrodynamic. Mechanical noise may be caused by vibration, resonance of parts inside the valve, inaccurate guidance of moving parts, or excessive clearance. The reason of aerodynamic noise is that the mechanical energy of compressible medium flow is transformed into sound energy. As the medium depressurizes, the released energy accelerates the flow of the fluid - usually exceeding the speed of sound - and produces noise. Hydrodynamic noise is generated by fluid flow. The specific conditions are as follows: collision between turbulence and valve and pipe wall, cavitation (cavitation) and evaporation (flash).
