Abstract
An emergency release device for butterfly valves comprises an upper butterfly valve, a lower butterfly valve and hoop assemblies, wherein a connection base and a connection flange are connected with both sides of each butterfly valve; the connection bases of the two butterfly valves are butted with each other; a hydraulic cylinder is mounted on the upper valve body; an upper push rod is connected with the hydraulic cylinder; a lower push rod facing the upper push rod is arranged on the lower valve body; and an expansion spring is arranged between a left hoop and a right hoop for increasing the opening speed of the hoops. A rotation shaft is transversely arranged on a hoop base; an axial limit device is arranged between the hoop base and the rotation shaft; and the left hoop and the right hoop are hinged with the rotation shaft on the hoop base through a vertical pin. In the case of emergency, the device can make an oil loading arm disconnected from a tanker through the separation of the upper valve and the lower valve. The two-body push rod facilitates the stability enhancement thereof as well as the noninterference quick detachment of the upper valve components and the lower valve components after the hoops are opened. When retracted, the push rod can be connected with an upper valve stem through one reset pin. The reset operation is simple and easy by the flexible use of the retraction force of the hydraulic cylinder.

During the oil transfer arm normal operation:
Upper valve body links to each other with oil transfer arm, and following valve body links to each other with the manifold flange of groove ship, and valve body links together by the anchor ear assembly up and down, and two butterfly valves are in open mode simultaneously up and down, and the return pin on this moment between the lower push-rod is removed.
Situation that something unexpected happened in the oil transfer arm operation process is necessary to make ship to separate fast with oil transfer arm, when guaranteeing device security, hydraulic actuating cylinder promotes two push rods up and down under hydraulic action, upper and lower spool swing arm is under two push rods promote up and down, rotate around the butterfly valve valve rod, butterfly valve cuts out gradually.
After butterfly valve cuts out fully, upper push-rod continues motion and promotes locking lever, locking lever is under the promotion of hydraulic actuating cylinder, locking lever rotates around the point of connection of locking lever and left clamping plate, when separating with right anchor ear to special washer, the anchor ear assembly is opened, and the spring that struts in the anchor ear assembly helps opening rapidly of anchor ear.Upper and lower valve body is thrown off fully, and upper valve body is faced upward with the oil transfer arm inner arm, and following valve body drifts about with ship.
During reset operation:
The operation oil transfer arm is docking together the Connection Block of upper and lower two valve members, loads onto the bolt that resets;
Drive hydraulic actuating cylinder hydraulic push rod is regained, when lower push-rod reclaims, be connected with upper push-rod with return pin, take back with hydraulic actuating cylinder then, after resetting, return pin must be taken off; Newspaper hoop assembly resets; Load onto shear pin; Close upper and lower two butterfly valves.
The utility model compared with prior art, in case of emergency, this device can make oil transfer arm and the disengagement of groove ship by the separation of valve up and down.Separate propulsive effort from hydraulic actuating cylinder, the fore and aft motion of hydraulic actuating cylinder is controlled opening of anchor ear and closing of butterfly valve by upper and lower two push rod transmission.When breaking away from, anchor ear is opened fast, makes two valves realize breaking away from.After disengaging, upper valve body links to each other with oil transfer arm and remains on the arm, and following valve body remains on the groove ship.The valve that adopts is to the folder butterfly valve; The push rod that adopts is a double-body bike, and be contained in respectively up and down on the valve body, after helping increasing the stability of push rod and anchor ear like this and opening up and down valve member do not have the quick separation of interference, when push rod reclaims, can make it upper valve rod with a return pin connects, use the recovery power of hydraulic actuating cylinder to reset flexibly, reset operation is simple.
