(54) ВИНТОВОЙ РЕГУЛИРУЕМЫЙ ДРОССЕЛЬ(54) SCREW ADJUSTABLE THROTTLE
II
Изофетение отнсх:итс к области ар матуростроени .Izofethene rel: ts to the field of armature construction.
Известен винтовой регулируемый дроссель по авт. св. № 594388, в корпусе которого размещен винт, причем- резьба винта срезана по конусу.Known screw adjustable choke on ed. St. No. 594388, in the case of which a screw is placed, with the screw thread being cut along a cone.
Недостатком известного дроссел вл етс то, что при большом расходе среды невозможно использовать всю длину дроссельного канала.A disadvantage of the known throttle is that with a large flow rate of the medium it is impossible to use the entire length of the throttle channel.
С целью повышени надежности винтова пара со стороны меньшего основани конуса снабжена участком с полным профилем резьбы, причем в теле винта выполнены осевой и радиальный каналы, а на поверхности прорезана кольцева канавка , соединенна радиальными каналами с осевым.In order to increase the reliability of the screw pair on the side of the smaller base of the cone, it is provided with a section with a full thread profile, the axial and radial channels in the body of the screw, and an annular groove connected to the surface with radial channels with an axial groove.
На чертеже изображен предлагаемый винтовой регулируемый дроссель.The drawing shows the proposed screw adjustable choke.
В корпусе 1 с входным 2 и выходны 3 каналами установлен винт 4. Часть резьбы винта 4 срезана по конусу, со стороны меньшего конуса винт снабженIn case 1 with input 2 and output 3 channels, screw 4 is installed. Part of the thread of screw 4 is cut along the cone; on the side of the smaller cone, the screw is provided
участком 5 с полным профилем резьбы, причем в теле винта выполнен осевой 6 и радиальш 1е 7 каналы. На поверхности винта прорезана кольцева канавка 8.section 5 with a full profile of thread, and in the body of the screw is made axial 6 and radial 1e 7 channels. An annular groove 8 is cut on the surface of the screw.
Работает дроссель следующим образом.Works choke as follows.
Среда поступает во входной канал, затем проходит в кольцевую канавку и далее через винтовой канал, образованный витками резьбы винта и корпуса, поступает в выходной канал.The medium enters the input channel, then passes into the annular groove and then through the screw channel formed by the turns of the screw thread and the housing enters the output channel.
При регулировании малых расходов винт глубоко ввернут в корпус. Дл увеличени расхода винт вывинчиваетс из корпуса до необходимой величины.When adjusting low flow rates, the screw is screwed deep into the case. To increase the flow rate, the screw is unscrewed from the body to the required value.
Дроссель обеспечивает возможность плавно регулировать расход среды в широких пределах, так как полный профиль резьбы на конце винта позвол ет использовать всю длину срезанного профил резьбы.The choke provides the ability to smoothly control the flow rate over a wide range, since the full thread profile at the end of the screw allows the entire length of the cut thread profile to be used.
