液压式天然气汽车加气子站及其回油卸气系统
摘要：
本发明揭示了一种液压式天然气汽车加气子站及其回油卸气系统，所述回油卸气系统包括：子站车，用于运输和储存压缩天然气；液压子站，用于提供高压液体；卸气装置，通过卸车软管与所述子站车连接，通过钢管与所述液压子站连接，所述卸气装置利用所述液压子站提供的高压液体控制所述子站车内的压缩天然气的卸载以及控制卸载完后的高压液体从所述子站车内返回至所述液压子站内；所述卸气装置独立于所述子站车和所述液压子站，且所述卸气装置位于所述子站车和所述液压子站之间。液压式天然气汽车加气子站包括上述的回油卸气系统。本发明液压式天然气汽车加气子站及其回油卸气系统的减少了卸车软管中的残压，减少气损。
摘要（英）：

The invention discloses a hydraulic refueling substation for gas-fueled vehicles and an oil-returning and gas-releasing system thereof. The oil-returning and gas-releasing system comprises a substation vehicle for transporting and storing compressed natural gas, a hydraulic substation for providing high-pressure liquid, and a gas-releasing device connected with the substation vehicle through an unloading hose and connected with the hydraulic substation through a steel pipe, wherein the gas-releasing device controls the unloading of the compressed natural gas in the substation vehicle in virtueof the high-pressure liquid provided by the hydraulic substation and controls the returning of the high-pressure liquid from the substation vehicle to the hydraulic substation after completion of theunloading, and the deaerator is independent of the substation vehicle and the hydraulic substation and located between the substation vehicle and the hydraulic substation. The hydraulic refueling substation for gas-fueled vehicles comprises the above oil-returning and gas-releasing system. The hydraulic refueling substation for gas-fueled vehicles and the oil-returning and gas-releasing system thereof in the invention reduce residual pressure in the unloading hose and lower gas loss.
