CS200901B1 - Mouth of the alarming smeller - Google Patents

Description

It is an object of the present invention to provide a sniffer orifice for easily detecting the presence of leaking gas from a corroded gas pipeline in the ground at the most dangerous locations.

The whipped cream mouths used so far in gas distribution systems have only the lid attached to the top of the whipped tube to prevent clogging or clogging of the sniffers with dirt. The presence of leaking gas is revealed by the fact that whipped creams are examined by gas workers after some time. This method of control is totally inadequate, since there may be a gas leak in the period between the last examination and the next, with all the subsequent harmful phenomena such as endangering the health and lives of persons, the tangible assets of national enterprises and residents, often unimaginable sizes.

The aforementioned drawback is remedied in accordance with the invention by providing an alarm smell mouth with a head having a horizontal opening in a horizontal position closed by a diaphragm provided with a sensor abutting a switch button with a power supply, electrical conductors, electric bulb and electric bell. the head of the sniffer at the top creates a closed vertical opening, closed by a dividing plate with an outlet opening, by-pass valve 'seal', which

200 901 is gripped by a guided lid, further provided with openings for leakage of gas escaping into the space between the lid and the plug seal provided with a threaded hole for engaging another audible alarm device.

Said embodiment achieves a permanent and continuous duplicate guarding in the alarming manner of escaping gas, even if the electric current circuit ceases to operate for any reason.

Depending on the design, the type of materials used to produce the moving parts, a safe alarm can be achieved even when the gas leaks between 5 and 10 mm water.sl.

The invention is illustrated by way of example in a vertical section of the accompanying drawing.

The mouth of the alarming sniff is formed by the head I, whose horizontal opening is closed by a membrane 2 having a sensor 2 * guided in a flange 4, which is fastened by screws 2 · electric switch 6 with pushbutton 2; 10 with the cover attached by screws 11. the upper vertical opening is provided with a separating plate 12 with an outlet opening 15. a relief valve as an additional sensor 14. above the separating plate is a seal 15 clamped by a lid 16 with a guide 12, gas passage holes 18, seal 19 gripped by a plug 20 with a threaded bore 21 for the elbow 22 'having a leakage gas outlet 25 for another not shown alarm alarm device - whistle or the like, the data are: power source 24, bulb 25. electric bell 26, electrical conductors 22 »28; to check the operation of the device, a threaded hole 29. a seal 50 and a bolt 51.

The activity of an alarming smell is as follows:

The escaping gas, which enters the top of the olfactory tube 52 into the play 2, causes overpressure in the head and deflects the diaphragm 2 together with the first sensor which pushes the switch 2 of the switch 6 to the position in which the current circuit closes. current 24, bulb 2 ^, el. the bell 26, the electrical conductors 22, 28, thereby actuating the alarm device, both audible and optical. Furthermore, by further increasing the overpressure inside the head, the second sensor-relief valve 14 is lifted and the leakage gas passage through the aperture 15 to the apertures 18 is passed through the duct to the threaded bore 21 in which the elbow 22 and the outlet 2 are screwed. for other not-drawn sound, alarm devices - whistle, etc., responsive to gas flow.

This quite simple and relatively inexpensive modification ensures that the alarming smell ensures continuous, uninterrupted monitoring of the endangered area in areas where the corrosive effects of stray currents on the gas grid and connections or in areas of aggressive, corrosive soils occur when the escaping gas from the corroded gas pipeline in the ground was stored, it was completely deprived of its characteristic odor due to odorization. As soon as a gas leak is alarmed by an alarming sniff, appropriate measures may be taken immediately by the gas field to prevent the risk of explosion or fire. This will also help to protect the health, lives and tangible assets of not only residents but also national enterprises.

The alarming sniffs in these corrosive areas can be advantageously used on house connections and industrial buildings connections from the outside close to the wall that the connection enters the building, provided that the passage of the outside wall connection is gas tight so that gas cannot enter beyond the inlet wall. of the connection inside the building along the poorly sealed passage of the gas connection in the wall and, in addition, wherever there are unused underground, non-covered spaces after sewerage, etc.
