The invention discloses an emergency disconnecting device for fluid loading and unloading and relates to the technical field of safety devices of fluid conveying pipelines. The emergency disconnecting device for fluid loading and unloading comprises a disconnecting valve which is provided with an upper valve body and a lower valve body; a covering clamping device is arranged outside the edge of a flange plate which is butt joint with the upper valve body and the lower valve body; the covering clamping device is connected with an opening device; internal chambers of the upper valve body and the lower valve body are provided with cone surfaces; the cone surfaces are provided with second seal rings; an upper valve element and a lower valve element which are provided with cone bodies are installed inside the upper cone body and the lower cone body; external ends of the upper valve element and the lower valve element are connected with pin shafts; first springs and spring seats respectively sleeve the pin shafts sequentially; supporting rods which are in butt joint are respectively arranged at internal ends of the upper valve element and the lower valve element; fluid channels are formed between the upper valve element and the upper valve body and the lower valve element and the lower valve body. Compared with the prior art, an opening device of the emergency disconnecting device for fluid loading and unloading can directly open the covering clamping device, the disconnection speed of the upper valve body and the lower valve body is more rapid, the two first springs respectively push the upper valve element and the lower valve element to seal a valve port, the closing is tight, and the closing sped is rapid.
Description
technical field [0001] The invention relates to the technical field of safety devices for fluid delivery pipelines, in particular to an emergency release device for loading and unloading fluids during offshore operations. Background technique [0002] The emergency release device is one of the key components in the LNG transfer device. It is related to the safety of offshore operations. The emergency release device can ensure the safety of the fluid during the transfer of LNG in ships to the greatest extent. There is an emergency release device for fluid loading and unloading. This emergency release device is equipped with two ball valves, the upper and the lower. The valve ports of the two ball valves are connected by flanges. , it is also equipped with a linkage device that closes the valve and opens the clasp clamping device at the same time during emergency disengagement. This emergency release device has the following problems in the use process: 1. When emergency rele...
