Description

Изобретение относится к устройствам для регулирования подачи топлива и может быть использовано в трактах топливоподачи на тепловых электростанциях.The invention relates to devices for regulating fuel supply and can be used in fuel supply paths at thermal power plants.

Целью изобретения является повышение экономичности.The aim of the invention is to increase efficiency.

На фиг. 1 изображена мигалка, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1. 10In FIG. 1 shows a flasher, a longitudinal section; in FIG. 2 is a section AA in FIG. 1.10

Мигалка содержит спускной стояк 1 с наклонным выходным конусом, косой срез которого перекрыт поворотным клапаном 2. Клапан 2 выполнен с отогнутым нижним концом 3, а его верхняя часть снабжена грузами 4 и 5, расположенными друг под другом. Верхний груз 4 является съемным и расположен в направляющих 6, а нижний груз 5 жестко закреплен в месте отги- 20 ба нижнего конца 3 клапана 2.The flasher contains a drain riser 1 with an inclined outlet cone, an oblique slice of which is blocked by a rotary valve 2. Valve 2 is made with a bent lower end 3, and its upper part is equipped with weights 4 and 5, located one under the other. The upper load 4 is removable and located in the guides 6, and the lower load 5 is rigidly fixed in the place of folding 20 ba of the lower end 3 of the valve 2.

Мигалка работает следующим образом.The flashing light works as follows.

Под воздействием веса столба топлива, находящегося в спускном стояке 1, клапан 2, установленный на валу, открывается и подает порцию топлива на сжигание. Благодаря тому, что выходной конец стояка 1 имеет косой срез, расположенный под углом к вертикали, клапан 2 под действием собственного веса закрывается. Отогнутый конец 3 клапана 2 позволяет уменьшить его габариты, а вес клапана создается грузами 4 и 5. Груз 5' создает, при отсутствии· груза 4, ми5 нимальный столб топлива в стояке 1, а полный набор грузов 4 и 5 - максимальный столб топлива, что соответствует минимальной и максимальной нагрузке котла. Грузы 4 и 5 могут 'выполняться не из металлического материала, например' кирпича, бетонных плиток и т.д., что снижает расход металла на устройство. Изменяя вес груза 4, можно регулировать высоту столба топлива от Минимальной к максимальной.Under the influence of the weight of the fuel column located in the drain riser 1, the valve 2 mounted on the shaft opens and supplies a portion of the fuel for combustion. Due to the fact that the output end of the riser 1 has an oblique slice located at an angle to the vertical, the valve 2 closes due to its own weight. The bent end 3 of valve 2 allows to reduce its dimensions, and the weight of the valve is created by loads 4 and 5. Load 5 'creates, in the absence of · load 4, a minimum fuel column in riser 1, and a complete set of cargoes 4 and 5 - the maximum fuel column, which corresponds to the minimum and maximum load of the boiler. Cargoes 4 and 5 may not be made of metal material, such as bricks, concrete tiles, etc., which reduces the consumption of metal on the device. By changing the weight of the cargo 4, you can adjust the height of the fuel column from Minimum to maximum.

Claims

The invention relates to devices for regulating the supply of fuel and can be used in the fuel supply paths at thermal power plants. The aim of the invention is to improve the economy. FIG. 1 shows a mikhalka, about a longitudinal incision; in fig. 2 shows section A-A in FIG. 1. The flashing light contains a drop out to 1 to 1 with a sloping output cone, the oblique cut KOTOpoio blocked by a rotary valve

2. The valve 2 is made with the folded lower end 3, and its upper part is provided with weights 4 and 5 located one under the other. The top load 4 is removable and located in the guides 6, and the bottom load 5 is rigidly fixed at the place of the back of the bottom end 3 of valve 2, the flasher works as follows. Under the influence of the weight of the fuel column, which is located in the discharge chamber 1, the valve 2 mounted on the shaft opens and delivers a portion of the fuel for squeezing. Due to the fact that the output end of the stopper 1 has a cuts slice located at an angle to the vertical, the valve 2 closes under the action of its own weight. The bare end 3 of valve 2 reduces its size, and the weight of the valve is created by weights 4 and b. Cargo 3 creates, in the absence of cargo 4, the minimum fuel column in stand 1, and the full set of cargo 4 and 5 - the maximum fuel column, which corresponds to the minimum and maximum load of the boiler. Weights 4 and 5 can be made from a non-metallic material, such as bricks, concrete tiles, etc., which reduces the metal consumption of the device. Rzmen cargo weight 4, you can rehulirovat height of the fuel column from the minimum to maximum. The invention of the flashing light for supplying fuel for combustion, comprising a drainage stand with a sloping output end having a slanting cut blocked by a rotary valve, so that, in order to improve efficiency, the valve is made with the bent lower end, and its upper part is provided with weights located one above the other, the upper weight being removable, and the lower part is rigidly fixed in place of the lower end of the valve.
