Abstract
The invention relates to a working method of an adjustable type sphere-shaped two-way pressure release valve. First, an adjusting screw rod is adjusted according to a set pressure of fluid, and thus the elastic potential energy of a spring is adjusted, and finally the pressure release value of the fluid in a fluid channel is controlled; when the pressure at one end of the adjustable type sphere-shaped two-way pressure release valve is greater than the pressure at the other end of the adjustable type sphere-shaped two-way pressure release valve, a sphere is pushed to move upward by the fluid, therefore space for the fluid to move is formed at the bottom of the sphere, so that the fluid can move in the fluid channel and the objective of pressure release can be achieved; and then the sphere is set back to the home position when the pressure at the left side of the sphere is equal to the pressure at the right side of the sphere. The method has the advantages of being capable of realizing two-way pressure release, simple in structure, stable in property, short in pressure release time, fast in pressure release speed, high in accuracy and good in sealability.
