The main function of the pressure regulating metering skid is to stabilize the outlet pressure after the pressure regulating metering skid under the condition of continuously changing inlet pressure and downstream flow. Generally, the pressure regulating skid consists of inlet and outlet valves, inlet filters, safety shut-off valves, monitoring pressure regulators, and working pressure regulators, among others. Among them, the important equipment includes safety shut-off valves, monitoring regulators, and working regulators, and the selection and configuration of these important devices largely determinePressure regulating metering skidthe quality and stability.

The important task of the pressure regulating metering skid is to regulate pressure, or in other words, to reduce pressure, so the pressure regulator is an important part of the basic adjustment and preparation. The natural gas metering skid has a basic function, but it also involves filtering, heating, deodorizing, and controlling. In the country, many pressure regulating stations or pressure regulating valves have problems, with over 90% caused by pipeline impurities, which is a problem of insufficient filtration.Pressure regulating metering skidFunction: Regulate output voltage, generally used in scientific research, experiments, testing, heating, insulation, soft start, and other occasions. Provide different voltages to the load, and the voltage can be linearly adjusted when powered on.

Working principle of the pressure regulating metering skid: The pressure regulating skid consists of five parts: inlet valve body, inlet joint, outlet joint, outlet valve body, and pilot. The inlet valve body is equipped with a main valve pressure control spring, high-pressure cylinder sleeve, and sealing membrane, etc. The valve body is equipped with a fixed valve seat, which consists of a sealing pair and a high-pressure cylinder sleeve. When the conduit is closed, the high-pressure oil cylinder is pressed against the fixed seat under the action of the main valve spring, sealing the medium inside the pressure regulating skid. When the pilot valve opens, the sealing membrane pulls the sealing membrane pressing plate to compress the spring, separating the high-pressure cylinder sleeve from the fixed seat and commanding the valve to open wider. The larger the gap between the high-pressure cylinder sleeve and the fixed valve seat, the higher the flow pressure and the greater the flow.

What should be noted when using the pressure regulating metering skid? 1. Spray warning signs on the surface of the pressure regulating skid or box, such as no collision and equipment number, or hang warning signs. 2. Check whether the static electricity measuring device meets the parameter requirements and whether each level of instrument is working normally. 3. Smoking or igniting is prohibited during the debugging process to avoid generating static electricity, and collisions, striking pipes, and pressure regulating skids are strictly prohibited. 4. Valves should be opened slowly and not opened or closed violently. 5. Regularly check and maintain the emergency shut-off valve, and the shut-off valve should be tested, checked, and maintained at least once a week.

Pressure regulating metering skidHow to choose? The working regulating valve is an important functional device of the pressure regulating metering skid, bearing important tasks for the entire station. Currently, there are three types of working regulating valves used in industry: self-operated regulating valves, pneumatic regulating valves, and electric regulating valves. We see that electric regulating valves are increasingly applied in various stations as working regulating valves. If the pressure regulating metering skid has pressure regulation or stabilization as its main task, the working regulating valve should choose a self-operated regulator; if both pressure regulation and current regulation are needed, a pneumatic control valve should be selected; if there are both pressure regulation requirements and current regulation requirements, but the station is not equipped with instrument air, then an electric regulating valve should be chosen.
