The invention relates to a high-pressure-resistant and high-sealing-performance heat pump air conditioner pressure release valve comprising a valve body, wherein a cavity is formed in the middle of the valve body, a sealing seat is arranged at the installation insertion end of the valve body, and an exhaust channel is formed in the middle of the sealing seat. A sealing ball, a sliding block and a spring are sequentially arranged in a cavity of the valve body, the sliding block is movably installed in the cavity and provided with an exhaust through hole, the sealing ball is arranged between the sliding block and the sealing seat, one end of the spring abuts against the sliding block, and the other end of the spring is limited by a limiting piece. Under a normal working condition, the sealing ball blocks the exhaust channel of the sealing seat and the exhaust through hole of the sliding block. Under in a high-pressure working condition, the exhaust channel of the sealing seat and the exhaust through hole of the sliding block are opened. For the characteristics of high pressure bearing, high temperature resistance and vibration resistance of the pressure release valve, the structure is set, and the use requirements of an existing electromagnetic valve are met by adopting tightening hard sealing through hardness differences of different materials.
