SU39939A1 - Adaptation for automatic inlet of water to the cupola spark arrester - Google Patents

Description

In plant practice, it is known that the start-up of water into the spark chamber of the cupola is produced by hand and, due to an accidental untimely start-up of water OR TOTALLY no water is supplied to the spark pot, the latter has burned out. For ustraya1a such; about the deficiency, as well as Dllg; Preventing the possibility of fire, proposes a fixture for the automatic inlet of water into the cupola spark chamber. In this device, a cylinder connected by an air line to the cupola and equipped with a piston connected by a lever transmission with a three-way valve located on the pipe supplying water to the spark box is used.

In the modified device, instead of a cylinder with a piston, a cylinder with a floating tube is used, with a cap acting on the valve by means of electrical contact and solenoids.

In FIG. 1 is a front view of a proposed fixture; FIG. 2 is a vertical section of it; FIG. 3 is a modified device with a partial section.

In the Scient of incorporation of air into the cupola air through the pipeline I

goes from cupola to cylinder 2 and forces piston 3 to lift upwards. The piston 3 of the cylinder 2 is provided with a rod 4, which, when lifted by means of the pull 5 and the lever 6, rotates the three-way valve 7, as a result of which water rushes out of the water supply network through the tap 8 of the faucet and then is directed to the cupola spark plug 9 of the tap 7.

When stopping to blow in the cupola, the air pressure on the piston 3 of the cylinder 2 stops; wherein the piston 3, under the action of the spring 10, worn on the rod 4, is lowered downwards

and 6, with itself tu 5 and the lever and with them the valve 7 is turned, which closes the passage of water from the water supply system through the branch pipe 8; since the supply of water in the pipeline to the spark arrester stops at the same time to avoid freezing of water in the pipeline, the remaining water goes down when turning the valve 7 through the pipe 11.

In the modified device, when turned on, the air in the cupola blows air from the pipeline through the flexible hose 1 to the cap 2, floating in the cylinder 3. Under the influence of pressure, the cap 2 rises and closes the co-tacts 4, so that the electromagnet 5 closing the contacts 6 draws the core 7, fitted at the end with a gear rack 8, which, being in engagement with the gear wheel 9 (shown by dotted lines); wedged at the end of the crane 10, turns the latter to the position indicated in the diagram, and thus opens the passage of water from the highway 11 through the channel of the valve 12 to the pipe 13 leading to the spark separator.

When switching off, the barking cap 2 in the cupola is lowered under the influence of its own weight and contacts 4 are opened; upon the termination of the electromagnet 5 gear rack 8, lowering under the influence of the weight of the gear 7, turns the valve 120 °. The passage of water from the main line is stopped, and a pipe 14 is opened, into which the water remaining in the pipe 13 is discharged to prevent it from freezing.

The subject matter of the invention.

Claims (2)

1. A device for automatic inlet of water to a cupola sparger, characterized by the use of an air line 1 with a cylinder 2 cupola, which is connected by a lever transmission system 4, 5, 6 with a three-way valve 7 of the pipeline that feeds water to the spark chamber (Fig. 1 and 2) . 2. The change of adaptation according to claim 1, characterized in that instead of a cylinder with a piston cylinder 3 is used with a floating cap 2 acting on the valve 12 by means of electrical contact and a solenoid (Fig. 3). fig g
