product overview

The pressure control system is a gas pressure regulating device designed specifically for natural gas long-distance pipeline stations, urban distribution stations, storage and distribution stations, power plant gas turbine supply, and other occasions, integrating multiple functional components such as pressure regulation, flow limiting, and automatic control. Also known as a 'pressure regulating train'.

The pressure control system is generally a gas pressure regulating device composed of the main equipment of "safety emergency cut-off valve+monitoring pressure regulating valve+working pressure regulating valve" connected in series from upstream to downstream, and matched with corresponding instruments and meters. At the same time, the main equipment can be configured in various ways such as self operated, electric, or pneumatic according to different user requirements and process requirements.

The entire system is supplied in a modular and sled mounted manner. The main equipment and related instruments in the system have been installed and manufactured in the factory, and have undergone individual inspection and overall performance testing. It has the characteristics of high precision, excellent performance, safety and reliability, reasonable structure, easy installation, and simple operation.

Under normal operating conditions, the safety emergency shut-off valve and monitoring pressure regulating valve are fully open, and the downstream outlet pressure is regulated by the working pressure regulating valve. When the working pressure regulating valve fails and cannot control the downstream outlet pressure, the monitoring pressure regulating valve takes over from the working pressure regulating valve to regulate the downstream outlet pressure. When the monitoring pressure regulating valve also malfunctions and cannot control the downstream outlet pressure, the safety emergency cut-off valve automatically and quickly closes, achieving the purpose of cutting off the airflow and ensuring the safety of the system.

Product Features

The optimized design scheme and series of products can meet the needs of urban natural gas transmission and distribution systems of different scales;

The safety emergency shut-off valve, pressure regulator, and regulating valve are all axial flow type, which has the characteristics of high flow rate, low pressure loss, and low noise;

The main form of voltage regulation is series parallel monitoring to ensure stable and reliable system operation with fast response speed;

◆ It can integrate station control within the station, and configure functional modules such as remote cut-off, pressure regulating valve and valve position remote transmission, commander electric heater, current and pressure limiting, and remote control and adjustment;

The design of the entire pressure regulating device mainly complies with domestic and foreign standards and specifications such as EN12186 "Functional Requirements for Gas Pressure Regulating Stations in Gas Supply Systems";

Various configuration methods can be adopted according to requirements, such as "safety emergency cut-off valve+monitoring pressure regulating valve+working pressure regulating valve", "safety emergency cut-off valve+monitoring pressure regulating valve+working regulating valve", "safety emergency cut-off valve+safety emergency cut-off valve+working regulating valve", etc.
