摘要： The open position of this pneumatic fuse valve is adjustable to change the rate of fluid flow at which the valve closes. The valve has static pressure balance when opened regardless of the pressure in the pipeline and even though the valve has a connection with the space surrounding the outside of its housing for inserting a means for overriding the actuator. This pressure balance permits adjustment of the valve when there is fluid pressure in the line and it permits the valve to be closed by a small force. A bleed connection equalizes pressure on both sides of the valve to permit it to open after the high rate of fluid flow that closed it has been shut off.
