text: The said arm of unloading a ship also comprises quick release unit, and said quick release unit comprises: be positioned at said outer arm near a mechanical chain mechanism of the end of said ethene output header and each ball valve of both sides thereof; When the pulling force that receives in said mechanical chain mechanism surpassed the pulling force setting value, said ball valve cut off the transfer passage of the liquid ethylene that self belongs to a side respectively, and said mechanical chain mechanism breaks off.
text: As shown in Figure 2, this arm of unloading a ship also comprises quick release unit 218, and this quick release unit 218 comprises: be positioned at the mechanical chain mechanism of outer arm 208 near the end position of ethene output header; And each ball valve of these mechanical chain mechanism both sides, under the normal condition, mechanical chain mechanism is in chain state; Two ball valves all are in the state of unlatching; Thereby make liquid ethylene waltz through liquid ethylene output header and get into outer arm, but when the pulling force that mechanical chain mechanism receives surpassed the pulling force setting value, these two ball valves cut off the transfer passage of the liquid ethylene that self belongs to a side respectively through mechanical chain mechanism; Promptly a ball valve cuts off the liquid ethylene output channel that ethene is exported header end one side; Thereby stop the output of liquid ethylene, another ball valve cuts off the liquid ethylene input channel on the outer arm, thereby stops the input of liquid ethylene; Mechanical chain mechanism can automatic disconnection; Thereby make outer arm 208 and ethene output header break away from annexation, prevent jolting or the excessive damage of the mobile range arm of unloading a ship of liquid ethylene cargo ship, cause liquid ethylene to reveal and cause security incident.
text: Simultaneously when unloading accidents such as boat landing one side breaking out of fire; Also can use the hand push button that is provided with to trigger quick release unit 218 on the bank; Make two ball valves cut off the transfer passage of the liquid ethylene that self belongs to a side respectively, and break off mechanical chain mechanism, thus the also annexation between automatic disconnection outer arm 208 and the liquid ethylene conveying ship; Conveying ship can be departed from port rapidly, avoid on the bank fire to cause the accident of conveying ship aspect.
