The invention relates to a balanced type water inlet and outlet valve group of an ultrahigh pressure supercharger. The novel balanced type water inlet and outlet valve group comprises an end cover (9), a long plug (8), a high-pressure one-way valve seat (5) and a high-pressure one-way valve core (6), wherein the end cover (9) is arranged on a high-pressure cylinder (2); the long plug (8) is arranged in the end cover (9); one end of the long plug (8) is extended into the high-pressure cylinder (2), and the other end of the long plug (8) is extended out of the end cover (9); and the long plug (8) is connected with a high-pressure water output joint (10). The novel balanced type water inlet and outlet valve group is characterized in that: the high-pressure one-way valve seat (5) is arranged on one end, which is extended into the high-pressure cylinder (2), of the long plug (8); the pressure born by an inner hole and an outer wall of the high-pressure one-way valve seat (5) is as same as that in the high-pressure
