Изобретение относитс к области противй пожарной техники и, в частности, к устройствам , обеспечивающим автоматическое ло- кальное тушение пожаров.The invention relates to the field of fire fighting equipment and, in particular, to devices providing automatic local extinguishing of fires.

Известен сприиклериый ороситель, содержащий корпус со щтуцером и распьшительной розеткой крышка которого снабжена, установленным соосно с корпусом запорнопусковым устройством, имеющим побудительный клапан, соединенный штоком с термочувствительным биметаллическим диском, и запорный клапан 1.Known splicer sprinkler, comprising a housing with a clamp and a spreading outlet, the cover of which is provided with a starting-up device mounted coaxially with the housing, having a trigger valve connected by a stem with a heat-sensitive bimetallic disk, and a stop valve 1.

Недостатком спринклериого оросител вл етс наличие трущихс пар и подвижного уплотиени , которое может заклинивать изза по влени накипи, а так же зффекта приваривани уплотнений, что может привести к отказу при работе устройства.A disadvantage of a sprinkler is the presence of rubbing pairs and a movable seal, which can jam due to the appearance of scale, as well as the effect of welding of the seals, which can lead to failure during operation of the device.

Цель изобретени - повышение надежности работы.The purpose of the invention is to increase the reliability of work.

Поставленна цель достигаетс тем, что в спринклерном оросителе, содержащем корпус со иггуцером и распылительной розеткой , крышка которого снабжена запорнопусковым устройством, имеюодам побудительный клапан, соединенный штоком с термочувствительным биметаллическим диском, и запорный кпашш, согласно изобретению запорно-пусковое устройство выполнено в виде сильфона с перепускным отверстием, один торец которого закреплен на крьшже, а запорный клапан установлен на другом торце сильфона.The goal is achieved by the fact that in the sprinkler sprinkler comprising a housing with an iggutser and a spray socket the staffs are equipped with a stop-starting device, the lid has a trigger valve connected by a stem with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the stop valve according to the invention is made in the form of a valve with a temperature-sensitive bimetallic disk, and the gate valve in the bypass hole, one end of which is fixed on the flange, and a shut-off valve is installed on the other end of the bellows.

На чертеже изображен с ринклерный оро10 штель.The drawing shows with a rinkler oro10 plug.

Спринклерный ороситель содержит кортус 1, дефлектор 2, крышку 3, к которой припа н сильфон 4 с перепускным отверстием 5 и запорным клапаном б, закрьтающим вы15 пускиое отверстие.The sprinkler sprinkler contains a cortus 1, a baffle 2, a cover 3, to which is attached a bellows 4 with an overflow opening 5 and a shut-off valve b, closing the opening 15.

В крышке имеетс центральное отверстие 7j перекрытое побудительным клапаном 8, установленным на одном штоке 9 с биме2JJ таллическим диском 10, который с двух сторон удерживаетс захватами 11. In the lid there is a central opening 7j blocked by an incentive valve 8 mounted on a single rod 9 with a bime2JJ with a circular disk 10 which is held on both sides by grippers 11.

Устройство работает следующим образом.The device works as follows.

Claims

The bimetallic Disk 10 is heated by the impact of the cushioned air flow in the center of fire and deflects the stimulating valve 8. The water pressure in the internal cavity of the bellows 4 drops sharply, the bellows compresses, the shut-off valve opens and the sprinkler starts to work. With a decrease in temperature, after the elimination of the center of fire, the bimetallic disk takes the same position. The pilot valve closes and the pressure in the cavity of the bellows is equalized around it. The bellows is opened and the shut-off valve closes the sprinkler outlet. This sprinkler sprinkler ensures reliable operation of the automatic fire extinguishing system in the safe mode. 4 The invention of the Sprinkler sprinkler, comprising a housing with a fitting and a spray outlet, the lid of which is provided with a shut-off device installed coaxially with the housing, which has a trigger valve connected to the stem with a temperature-sensitive bimetallic tree, and a shut-off valve that is designed so as to improve reliability operation, the starting and starting device is made in the form of a bellows with an overflow hole, one mountaineer of which is fixed on the lid, and the stop valve is installed on the other end of the sylph on.
