Парораспределительный механизм дл паровых машин компаундSteam distribution mechanism for steam engines compound
пр мого действи direct action
За влено 9 августа 1946 года в Министерство путей сообщени СССР за № 5536 (347097) Опубликовано 31 августа 1948 годаFiled August 9, 1946 to the USSR Ministry of Railways under the number 5536 (347097) Published on August 31, 1948
Изобретение касаетс усовершенствовани известных парораспределительных механизмов дл паровых Л1ашин компаунд пр мого действи с одним парораспределительным поршневым золотником, приводимым в действие паром, поступающим по каналам , открываемым поршнем при подходе его к крайним положени м.The invention relates to the improvement of the known steam distribution mechanisms for steam steam compressors of direct action with a single piston steam distribution piston spool actuated by steam coming through the channels opened by the piston as it approaches its extreme positions.
Целью предлагаемого изобретени вл етс упрош;ение конструкции парораспределительного механизл1а.The aim of the invention is to improve the design of the steam distribution mechanism.
Согласно изобретению, это достигаетс тем, что сообш;ение нерабочей стороны цилиндра низкого давлени с атмосферой производитс золотником через кольцевую полость, ограниченную уплотнительными поршневыми кольцами и стенками парового цилиндра высокого давлени .According to the invention, this is achieved by communicating the non-operating side of the low pressure cylinder with the atmosphere by a spool through an annular cavity bounded by sealing piston rings and walls of the high pressure steam cylinder.
На чертеже изображена схема предлагаемого механизма.The drawing shows a diagram of the proposed mechanism.
Поршень 77 цилиндра высокого давлени имеет удлиненную форму, в соответствии с чем длина цилиндра высокого давлени увеличена по сравнению с цилиндром низкого давлени . Поршневые уплотнительные кольца и стенки цилиндра высокого давлени обра6The high-pressure cylinder piston 77 has an elongated shape, whereby the length of the high-pressure cylinder is increased compared with the low-pressure cylinder. Piston O-Rings and High Pressure Cylinder Walls
зуют выхлопную камеру, котора при всех положени х поршн сообщаетс с атмосферой через канал 7. Механизм имеет один симметричный трехдисксвый золотник 9.The exhaust chamber is connected, which at all positions of the piston is in communication with the atmosphere through channel 7. The mechanism has one symmetric three-disc valve 9.
На чертеже изображено положение, когда свежий пар, поступа по каналам 7 и 2 в нижнюю полость цилиндра высокого давлени , перемещает поршень 77 в верхнее положение . Одновременно с этим пар из верхней полости цилиндра высокого давлени , поступа по каналам 3 и -/ в верхнюю полость цилиндра низкого давлени , перемещает поршень 70 вниз. Нижн полость цилиндра низкого давлени каналами 5, 6 и 7 сообщена с атмос(|)ерой.The drawing shows the position when fresh steam, flowing through the channels 7 and 2 into the lower cavity of the high-pressure cylinder, moves the piston 77 to the upper position. At the same time, steam from the upper cavity of the high pressure cylinder, flowing through the channels 3 and - / into the upper cavity of the low pressure cylinder, moves the piston 70 downwards. The lower cavity of the low pressure cylinder is connected by channels 5, 6 and 7 with the atmosphere (|) of the cylinder.
Когда поршень цилиндра высокого давлени приходит в крайнее верхнее положение, то канал S оказь ваетс сообщенным с нижней полостью , и пар, проника к торцевой поверхности золотника, перемещает его вниз. При этом свежий пар начнет поступать по каналам 7 и 3 в верхнюю полость цилиндра высокого даглени , а из нижней полости по каналам 2 и 5 в нижнюю полость цилиндраWhen the piston of the high-pressure cylinder comes to its extreme upper position, the channel S turns out to be in communication with the lower cavity, and the steam, penetrating to the end surface of the slide, moves it down. At the same time, fresh steam will start to flow through channels 7 and 3 into the upper cavity of the high-pressure cylinder, and from the lower cavity through channels 2 and 5 into the lower cavity of the cylinder

низкого давлени . Верхн полость цилиндра низкого давлени каналами 4, 8 и 7 сообщена с атлюсферой. Когда поршень цилиндра низкого давлени займет верхнее положение, а поршень цилиндра высокого давлени займет нижнее положение, давлениелг пара, поступающего через канал 6, золотник будет подн т вверх, и цикл работы повторитс .low pressure. The upper cavity of the low pressure cylinder is communicated with channels 4, 8 and 7 with the atmosphere. When the low-pressure cylinder piston takes the upper position, and the high-pressure cylinder piston takes the lower position, the pressure of the steam flowing through channel 6 will raise the valve and the cycle will repeat.
