Selection and Technical Innovation of Pneumatic Pressure Control Valve
- صمام ديلكو
Pneumatic Pressure Control Valve is a key device in industrial automation system. In this article, DELCO Valve will discuss in detail its selection suggestions, technical innovations and application cases.
Working Principle of Pressure Regulation
Pneumatic Pressure Control Valve adjusts the opening of the valve by pneumatic actuator, so as to precisely control the pressure of the medium. The basic principle is to use a gas source to drive the piston or diaphragm, according to the feedback pressure to adjust the valve opening.
Technological innovation
- Automation control: through integration with PLC or DCS systems, remote monitoring and automatic adjustment can be realized.
- Improved precision: New actuator design improves the sensitivity and stability of pressure adjustment.
- Environmentally friendly design: optimized pneumatic system design reduces compressed air waste.
Application Scenarios
- Chemical Industry: In reactors, the Pneumatic Pressure Control Valve is used to control the internal pressure and ensure the stability of the chemical reaction.
- Steam systems: In boilers and heat exchangers, steam pressure is regulated to optimize energy utilization.
- Natural gas industry: For pressure stabilization in long-distance transmission pipelines to ensure safe transmission.
Selection and Installation
- Pressure Range: Ensure that the rated pressure of the valve covers the system requirements.
- Material selection: such as stainless steel for corrosive media, cast steel for high temperature and high pressure conditions.
- Actuator type: single-acting for emergency shutdown, double-acting for high-frequency operation.
Maintenance and Common Problem Solving
- Periodic calibration: to ensure the accuracy of pressure control and avoid system fluctuation.
- Troubleshooting: If the pressure is unstable, check the air source pressure and whether the spool action is smooth.
- Replacement of wearing parts: Replace seals and diaphragms regularly to prolong the life of the equipment.
