Pressure relief valve is a kind of valve that can automatically keep the outlet pressure stable by adjusting the inlet pressure to a required outlet pressure and relying on the energy of the medium itself. From the point of view of fluid mechanics, the pressure relief valve is a throttle element whose local resistance can be changed. That is to say, by changing the throttle area, the flow velocity and fluid kinetic energy can be changed, resulting in different pressure losses, so as to achieve the purpose of pressure relief. Then, the fluctuation of the back pressure of the valve is balanced with the spring force by the adjustment of the control and regulation system, so that the back pressure of the valve remains constant within a certain error range.
