Embodiments of the present application provide an integrated pressure retaining valve, an air suspension system and a vehicle, which relates to the field of vehicle technology. The integrated pressure retaining valve includes a valve housing, a pressure retaining component and a fixing component, where the pressure retaining component includes a valve core, a reset piece and a first sealing piece, the first sealing piece is fixed on the valve core, the reset piece is connected between the valve housing and the valve core; and the fixing component includes a fixing piece. In an installation process of the air suspension system, the integrated pressure retaining valve is connected to an airport of an air spring, and the reset piece of the integrated pressure retaining valve applies a force to the valve core, so that the first sealing piece can seal the first end and the integrated pressure retaining valve is in a pressure retaining state, thereby ensuring an internal gas pressure of the air spring and avoiding adjustment of a shape of the air spring. After that the air spring is installed to a frame, then the air duct is directly inserted into the integrated pressure retaining valve, the air duct is fixed by the fixing piece, to conduct the air duct with the airport of the air spring, making the installation process of the air suspension system time-saving and labor-saving.
