The invention provides an inclined bi-directional pressure-bearing valve with a V-shaped sealing structure. The inclined bi-directional pressure-bearing valve comprises a valve body, a valve seat, a valve element and a valve shaft, wherein a V-shaped sealing ring is assembled at the end part of the valve element through a compression ring and a adjusting screw; the V-shaped sealing ring comprisesa sealing part, a clamping part and an inward concave part; the two sides of the clamping part of the V-shaped sealing ring are tightly clung to the compression ring and the valve element separately;the sealing part is in contact with the valve seat; in a sealing state, a first allowance space is formed between the compression ring and the valve element, a second allowance space capable of performing micromovement towards a water inlet is reserved between the valve seat and the valve body, a small hole is formed in the compression ring, and the inward concave part of the V-shaped sealing ringcommunicates with a water outlet through the first allowance space and the small hole; and when a medium of the valve flows back, the medium flows into the first allowance space through the small hole and enters the V-shaped sealing ring to reach the inward concave part, and the V-shaped sealing ring deforms under the pressure effect of the medium to enable the sealing part to protrude to be in contact with the valve seat. The inclined bi-directional pressure-bearing valve with the V-shaped sealing structure has the benefits as follows: the problem as following is solved: when the medium of the conventional valve flows reversely, the sealing property of the valve is poor.
