[0002] A pressure regulating station is a device used to reduce the pressure of fluid in a pipeline, usually used to reduce the pressure of high-pressure gas or liquid to a suitable working pressure. A pressure regulating station is usually composed of a pressure reducing valve, a pressure gauge, a safety valve, etc., which can ensure that the fluid in the pipeline system operates within a suitable pressure range. The discharge interface of the pressure regulating station is usually in a closed state. When the pressure regulating station is maintained, it is necessary to remove the seal at the discharge interface, connect the hose, and tighten it with a pipe clamp before the discharge can be carried out. During the operation, one person needs to control the interface to prevent the hose from falling off, and the other person needs to hold a fire extinguisher at the discharge port for protection.
