Hawk Tube manufacturers introduce you to the normal working state of the emergency breakaway valve for loading鹤tubes. Let's take a look together.
1. Normal Operation: After the crane pipe is connected to the tanker, first manually remove the safety bolts (simply unscrew the dovetail nuts), then you can open the valve for loading and unloading operations. After completing the loading and unloading, reattach the safety bolts and proceed with the disconnection of the crane pipe from the tanker to reset the crane pipe.
Emergency Break Description: During normal loading and unloading of the hopper car, the wire rope breaking mechanism is in a relaxed and free state. As the hopper car departs, its interface enters the warning zone; the wire rope tensions and gradually extends, becoming elongated until it exceeds the limit range and enters the breaking zone.
Firstly, cut the cotter pin that connects the cone top and the connecting shaft.
Next, the securing ring is pulled out of the panel's projection.
5. The pyramid structure opens the left/right clamping boards, achieving the separation of the device.
Post-separation, one cut-off valve remained on the crane's outer arm, while the other was left on the hopper truck (along with the crane's front-end rotating joint, ball valve, quick connector, etc.). Both cut-off valves achieved sealing under the force of internal springs.
