SU13614A1 - Fire protection device for open storage vessels for flammable liquids - Google Patents

Description

The present invention relates to a fire prevention device for open vessels for storing flammable liquids, provided with low-melting inserts in a mechanism that holds the hinged lids of these vessels in a raised position.

In the schematic drawing of FIG. 1 shows a front view of a vessel equipped with the proposed device; FIG. 2 - section AB line s & FIG. one; FIG. 3 and 4, on a larger scale, are side and front views of the proposed fixture.

The hinged lid of the vessel (Fig. 1) has a strut attached to the hinge side with a roller at the end that rests on the doggie, thereby preventing the lid from slamming under the action of the spring G. The doggie under the action of the spring It tends to rotate around the d axis in the direction indicated by the arrow (Fig. 2) and is held in the initial position by the thrust rod and, riveted end to the tank wall and having a low-melting insert to. When the lid is opened, the strut roller S rolls along the direction I and gets on the dog in, after which the lid remains stationary. Raise the lid to close the lid.

strut 6 and move it through the dog in, after which the roller rolls papravl yuschi5 I.

During a fire or when the temperature in the vessel rises to a certain value, the fusible link k melts, the spring e throws the dog in the direction of the arrow, the strut ff, no more resistance, slides the roller along the guides, and the lid closes under the action of the spring r access of oxygen and therefore further burning of the liquid. In order to bring the vessel to readiness for further work, the installation of a new low-melting link is required.

The whole mechanism is attached to the inner side wall of the vessel and is protected by the casing t from accidental impacts that may occur during operation and if foreign objects hit it.

The subject of the patent.

Fire protection device for open vessels for the storage of easily flammable liquids, fitted with .lerKo fusible inserts in the mechanisms that hold the flap in a raised position

the lids of these vessels, characterized by being rotated around the axis d, under the action of the spring e, the pawl, which serves as a stop for the hinged strut b of the lid a, is connected by the vessel body by means of a pull-in, including the said fusible insert to, with closing the lid when the link is melted, a spring g is provided, and guides are provided for installing the lower end of the strut (D opposite the pawl).
