Oil pressure soft bypass valve

The utility model belongs to an oil pressure soft bypass valve. The following technical scheme is adopted: the oil pressure soft bypass valve comprises an end cover (1), an end cover bolt (9), and a valve body (7) provided with a fluid inlet (71) and a fluid outlet (72); and the oil pressure soft bypass valve is characterized in that a valve body cavity (73) is formed in the valve body (7), the valve body cavity (73) is connected with the fluid inlet (71) and the fluid outlet (72), and the valve body cavity (73) is further slidably connected with a piston (8); the piston (8) is composed of a clapboard (81), a piston upper part (82) and a piston lower part (83); the piston upper part (82) is connected with a spring gland (3) via a spring (5), the spring gland (3) is connected with a screw rod (6) and the valve body cavity (73), and the screw rod (6) is connected with the end cover (1); and a piston hole (84) is formed on the piston lower part (83). The oil pressure soft bypass valve has the beneficial effects of solving problems of vibration and turbulence, as well as achieving dual effects of a safety valve and an adjusting valve.
