To understand the control valve maintenance, we will have to first understand what is the control valve? There Jiangyin Oulei Si valve repair factory to introduce you to: control valve, also known as the regulating valve (control valve, GB GB / T 1721.1-1998 defined for the control valve), automatic control of the terminal control element, the decision process control whether timely and effective system security is more important in the control loop, but is a long-standing technical weakest link. The control valve is a user operating conditions tailored products, many domestic and foreign manufacturers, the control valve varieties, specifications, multi-parameter, the quality is also poor arrhythmia. Differences of different manufacturers of the same type of control valve design, technical characteristics and application of how an issue of concern.
The valve body is a main part of the valve for connecting pipes and the fluid passage, and the placement of the valve member to contact with various media, and is exposed to fluid pressure, should be consistent with the use of pressure, temperature, erosion, etching conditions and other requirements in various aspects and according to the engineering practice, the installation requirements of the decision of the valve shape, structure and connectivity. Body type, material is its two elements. Control valves in process control plays an important role, the valve body is directly in contact with the process flow path, to safeguard various media circulation and is exposed to the fluid pressure and adapt to the conditions required, the shape, structure, and connections to meet user needs.
The correct choice of valve type, the flow path of the rational design of the valve body, the economic use of the valve body material production and customization of the basic requirements of the control valve to explore the characteristics of different valve body details, from the overall optimization of industrial process control valves can be used in a variety of conditions to meet safety and environmental requirements.
