The invention discloses a multi-way valve with oil filling function based on one-way or two-way hydraulic lock, which comprises a main valve body. The main valve body is provided with a main valve hole, a main stem, a shuttle valve hole and shuttle valve core. The main valve body is provided with an oil path A and B; an oil channel AC and an oil channel BC are arranged between the shuttle valve hole and the main valve hole, and an oil channel AP and an oil channel BP are sequentially connected with the oil inlet P on the main valve hole. The main valve hole is also provided with oil outlet TA and oil outlet TB; the shuttle valve hole on the outer side of both ends of the shuttle valve core is sealed with one-way valve and one-way valve or sealing end cap, the first shuttle valve alignment device is installed between the one-way valve and shuttle valve core, and the second shuttle valve alignment device is installed between the sealing end cap and shuttle valve core; when oil circuit A is overloaded, oil circuit B can be under the action of oil return resistance. Oil is replenished through the path of oil outlet TB oil channel BC oil channel B. When oil channel B is overloaded, oil channel A replenishes oil, and the spring stiffness of traditional one-way valve of hydraulic lock is greatly reduced.
