[0004] In the existing liquefied natural gas device, the flow rate of natural gas is counted and the pressure is adjusted by the pressure regulating and metering valve in the pressure regulating and metering skid. During the production and transportation of natural gas, the corrosion of the inner wall of the pipeline will produce some debris. The debris will be blocked when passing through the pressure regulating and metering valve and form stubborn stains on the inner wall of the pressure regulating and metering valve. When the inner wall of the pressure regulating and metering valve is cleaned, the cleaned debris will still fall into the pressure regulating and metering valve, so that the dirt will still flow in the natural gas pipeline. In order to solve the above problems, a pressure regulating and metering equipment maintenance and cleaning device is proposed in the present application. Utility Model Content
