Introduction The pressure regulating and metering skid of LNG station is composed of valve, filter, pressure regulator, flow meter, shut-off valve, safety relief valve, bromination machine and other main components, which provides stable and reliable gas supply for downstream and is suitable for pressure regulating and metering of normal temperature gas after gasification in LNG Reserve Station. Features Features of pressure regulating and metering skid: 1. It integrates pressure regulating, metering, filtering, safety cutting and safety releasing;2. The equipment is stable, safe and reliable, and easy to maintain;3. The equipment is easy to install and debug, reasonable in structure and suitable for indoor and outdoor installation;4. Box materials are: steel spray box, stainless steel box, color steel insulation box, which can meet the needs of different environments of users;5. It is suitable for natural gas, artificial gas, coke oven gas, liquefied petroleum gas, gas and other gases. Maintenance Before the maintenance of the pressure regulating and metering skid, the front and rear valves of the pressure regulating channel must be closed and the pressure released before the pressure regulator can be disassembled or disassembled. After the final assembly, check whether the moving parts can move flexibly, and then carry out the air tightness test, check the outlet pressure setting value of the pressure regulator, and check the closing pressure.The operation management department shall adjust the daily maintenance and regular inspection cycle of the pressure regulator according to the temperament and use conditions, and timely inspect and replace the seals of the pressure regulator, so as to ensure the safe and normal gas supply.
