The important role of the pressure regulating metering skid is to stabilize the outlet gas pressure under the condition that the inlet gas pressure and the total flow rate downstream are constantly changing.Pressure regulating metering skidThe pressure regulating lever consists of the import and export trade doors, the inlet filtering device, safety shut-off valves, detection regulators, and working regulators. Among them, the key machines are the safety shut-off valve, the monitoring regulator, and the working regulator. The selection and configuration of these key devices depend to some extent on the quality and reliability of the pressure regulating metering skid.

Introduction to the key points of pressure regulating metering skid:

Pressure regulating metering skidThe main goal is to adjust the gas pressure or reduce the gas pressure, so the regulating valve is an essential component of complete adjustment and arrangement. The gas metering station is a basic element, but it also involves filtering, heating, deodorizing, and control. In China, many pressure regulating stations or doors have problems, with over 90% caused by pipeline residues, which is a filtering issue. The pressure regulating function of the metering lever: adjusting voltage, generally used in research, experiments, inspections, heating, insulation, soft start, and other places. The load is given different types of working voltage, which can be linearly adjusted as the power supply is turned on.

Principle of pressure regulating metering skid: The pressure regulating skid consists of an intake valve body, intake connector, exhaust pipe connector, exhaust valve body, and five components. The intake valve body is equipped with a main pressure-controlled torsion spring, a high-pressure cylinder sleeve, and a sealing membrane. Inside the valve body, there is a fixed seat composed of a sealing pair and a high-pressure cylinder sleeve. When the hose is closed, the high-pressure cylinder approaches the fixed seat under the action of the main spring, sealing the material in the pressure regulating skid. The sealing membrane drives the torsion spring of the sealing membrane pin, separating the high-pressure cylinder sleeve from the fixed seat, commanding each section to amplify. The greater the gap between the high-pressure cylinder sleeve and the fixed seat, the greater the flow gas pressure and the more flow.

What should be noted when using the pressure regulating metering skid? 1. Warning signs should be sprayed on the pressure regulating skid or box. If there are no impact and equipment numbers, or suspension warning signs. 2. Regularly check whether the static electricity measuring equipment meets the main parameter requirements and whether each instrument is functioning properly. 3. Smoking or igniting is strictly prohibited during the adjustment process to prevent static electricity discharge. Hitting, knocking pipes, and prying adjustments are prohibited. 4. Each section should be opened slowly, and cannot be opened or closed violently. 5. Regular maintenance and maintenance of emergency shut-off valves should be conducted at least once a week, with regular maintenance checks.

How to choose a pressure regulating metering skid?Pressure regulating metering skidIt is the basic functional equipment of the pressure regulating skid, responsible for the basic tasks of the entire station. Currently, there are three types of working regulating valves used in industry: automatic regulating valves, pneumatic regulating valves, and electric regulating valves. The electric regulating valve you see is increasingly used in every process. If the pressure regulating skid is primarily tasked with adjusting or stabilizing gas pressure, the working stabilizing power supply should choose a self-regulating power supply; if both gas pressure adjustment and current adjustment are needed, a pneumatic regulating valve should be chosen; if there are requirements for both gas pressure adjustment and current adjustment, but the station is not equipped with a CPU, then an electric regulator should be chosen.
