The pressure regulating and metering skid is generally composed of inlet and outlet valves, incoming filters, safety shut-off valves, monitoring pressure regulators, working pressure regulators (or working regulating valves), etc. Among the important equipment are safety shut-off valves, monitoring regulators and working regulators. The selection and configuration of these important equipment largely determines the quality and stability of the product. Because the reason why it is called the pressure regulating and metering skid, its important task is to regulate the pressure, or reduce the pressure, so it is the most important thing in the basic adjustment.
Equipment Debugging:
1. Set the pressure, follow the guidelines from high to low, and proceed step by step, namely: cut off the pressure - release the pressure - work pressure.
2. After the pressure is set, it is necessary to detect its closing pressure to verify its function and whether it reaches the required value.
3. The outlet valve can be opened only after the pressure setting meets the requirements. Before that, the outlet valve must not be opened to prevent accidents.
4. Precise instruments should be protected to prevent large pressure fluctuations and damage to the instrument.
5. During equipment debugging, if uninterrupted gas supply is required, the pressure should be manually controlled through the bypass first, the pressure regulating valve should be manually controlled, the pressure gauge should be hand-held, and the pressure changes should be checked at all times to keep the outlet pressure within the required pressure range. After the pressure setting of the regulator is completed, slowly open the outlet valve of the regulator, and then close the bypass valves after the normal gas supply of the pressure regulating and metering skid.
