Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically, it relates to a disconnectable valve for fluid loading and unloading. Background Technology

[0002] When transporting fluid goods, it is necessary to transfer the fluid goods from the freight station to transport vehicles such as tank cars, trains or ships, or to transfer the fluid goods in the transport vehicle into the freight station.

[0003] During fluid loading and unloading, especially with hazardous fluids (such as flammable, explosive, toxic, or harmful fluids), unexpected situations such as sudden movement of transport vehicles or significant external forces pulling on pipelines can easily lead to the disconnection of the pipeline from the valves. If the fluid transport channel cannot be cut off in time, it can result in serious leaks, posing a significant threat to personnel safety and the environment. Existing ordinary valves are unable to effectively shut off the fluid in such situations in a short time, lacking the ability to respond to emergencies and thus causing substantial losses.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A disconnectable valve for fluid loading and unloading includes a valve body with a feed pipe and a discharge pipe connected to its two ends. Both the feed pipe and the discharge pipe extend into the valve body from opposite ends. Symmetrically arranged sealing mechanisms are installed inside the valve body, located at the ends of the feed pipe and the discharge pipe. Each sealing mechanism includes a sealing plate, a fixing frame, a mounting frame, a support spring, a rotating shaft, a mounting seat, a support rod, and a connecting frame. Two sealing plates and two fixing frames are symmetrically arranged. The fixing frames are fixedly connected to the inner wall of the valve body. The rotating shaft is rotatably mounted on the fixing frame. The mounting seat is fixedly connected to the outer wall of the rotating shaft. The sealing plate is fixedly connected to the outer wall of one side of the mounting seat. The sealing plate contacts the inner wall of the valve body, the outer walls on both sides of the feed pipe end, and the outer walls on both sides of the discharge pipe end.

[0007] In a preferred embodiment of this utility model, the valve body is provided with a feed inlet and a discharge outlet at both ends, the guide pipe is connected to the inner wall of the feed inlet, and the discharge pipe is connected to the inner wall of the discharge outlet.

[0008] As a preferred embodiment of the utility model, the first connecting flange and the second connecting flange are connected through bolts.

[0009] As a preferred embodiment of the utility model, the installation groove is arranged on the inner wall of the valve body, and the support spring is connected to the inner side of the installation groove.

[0010] As a preferred embodiment of the utility model, the mounting bracket is fixedly installed on the inner wall of the valve body, and the support rod is hingedly arranged on the mounting bracket.

[0011] As a preferred embodiment of the utility model, the connecting bracket is fixedly connected to the outer wall of the plugging plate, and the support rod is hingedly arranged on the connecting bracket.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When the guide pipe or the discharge pipe is disconnected from the valve body due to an unexpected situation, the guide pipe or the discharge pipe moves to the outer side of the valve body, at this time, the plugging plate in the plugging mechanism rotates and resets to the vertical state under the action of the support spring, the rotating shaft, the mounting seat, the mounting bracket, the support rod and the connecting bracket, so that the two plugging plates are in contact with each other, and the feeding port or the discharge port is plugged, the valve body and the pipeline can be separated in a short time, the fluid passage is cut off, the fluid leakage accident caused by the unexpected situation is effectively avoided, and the personnel safety and the environment are protected.
