The invention discloses a pressure regulating valve and a vehicle. The pressure regulating valve comprises a first shell, a second shell, a first pipeline, a second pipeline and a pressure regulating core, an air outlet channel is defined by the first shell, the first shell is further provided with an air outlet, the air outlet is communicated with the air outlet channel, the second shell is arranged around the side wall face of the first shell and forms an air inlet channel, the second shell is further provided with an air inlet, and the air inlet channel is communicated with the air inlet channel. The air inlet is communicated with the air inlet channel; a first vent is formed in the side wall surface of the first shell, one end of the first pipeline is connected with the first vent, and the other end is connected with the condensation mechanism; a second vent is formed in the side wall surface of the second shell, one end of the second pipeline is connected with the second vent, and the other end is connected with the condensation mechanism; the pressure regulating core body is arranged in the air outlet channel, the pressure regulating core body is provided with a shielding position for shielding the first air vent and a pressure regulating position for avoiding the first air vent, and the pressure regulating core body reciprocates between the shielding position and the pressure regulating position. According to the technical scheme, high-temperature gas generated in the using process of the fuel tank can be reduced, the internal pressure in the fuel tank is reduced, and the expansion deformation condition of the fuel tank is reduced.
