This utility model relates to the field of natural gas transmission technology and discloses a skid-mounted outlet valve assembly for a natural gas station, including a skid-mounted platform, a support frame, a temperature control mechanism, and a conveying mechanism. The skid-mounted platform is fixedly connected to the support frame, and the conveying mechanism is laid on the support frame. The temperature control mechanism is fixedly connected to the skid-mounted platform, and the conveying mechanism is connected to the support frame. This utility model extends the heating end of the heating device into the interior of the water tank. In hot weather, to ensure the structural safety and normal operation of the device, a water pump draws water from inside the water tank through a pumping pipe and delivers it to the nozzles through a water supply pipe to cool the device and its surrounding environment. This prevents the sealing gaskets at the pipe valve connections from expanding due to excessive temperature, which could affect the sealing performance. Through multi-stage control of the inlet gate valve and the shut-off valve, the device can respond in case of abnormalities, avoiding accidents.
