Abstract
The invention relates to methods for interrupting a flow of liquid and can be used in various branches of engineering for a discontinuous supply of liquid, for treating various materials with a liquid, and also in fuel nozzles. In the present method for interrupting a flow of liquid, the flow cross section is closed off by a shut-off element executing a translational movement coaxial with respect to the direction of the flow, the direction of flow is unchanged, the shut-off element is activated by the substance flow itself, and, in order to open up the flow cross section, an external force is generated which is applied to a return mechanism. The method makes it possible to increase the accuracy with which the device operates as a shut-off valve, to increase the speed with which a flow is cut off, to apply the method to flows with high and low flow rates, and also to alleviate pressure on the shut-off element.
Description
СПОСОБ ПРЕРЫВАНИЯ ПОТОКА ЖИДКОСТИ И УСТРОЙСТВО, РЕАЛИЗУЮЩЕЕ СПОСОБ METHOD FOR INTERRUPTING A FLUID FLOW AND A DEVICE IMPLEMENTING A METHOD
ОПИСАНИЕ DESCRIPTION
Изобретение относится к способам прерывания потока жидкости, и может быть использовано в различных областях техники для прерывистой подачи жидкости, для обработки жидкостью различных материалов, а также в топливных форсунках. The invention relates to methods for interrupting the flow of liquid, and can be used in various fields of technology for intermittent liquid supply, for processing various materials with liquid, as well as in fuel nozzles.
Из уровня техники известны различные способы и устройства для прерывания потока жидкости. Сюда относятся различные виды запорной арматуры, а также механизмы регулировки и стабилизации потока жидкости. Недостатками известных из уровня техники способов и устройств, служащих для прерывания потока жидкости, являются недостаточная точность работы, низкое быстродействие (время перекрытия потока), невозможность применять один и тот же способ для потоков с большим и с малым расходом. Various methods and devices for interrupting a fluid flow are known in the art. This includes various types of valves, as well as mechanisms for regulating and stabilizing the fluid flow. The disadvantages of the prior art methods and devices used to interrupt the fluid flow are insufficient accuracy, low speed (time to shut off the flow), the inability to use the same method for flows with high and low flow rates.
Задачей изобретения является повышение точности работы устройства как запирающего клапана, повышение быстродействия перекрытия потока, возможность применять способ для потоков с большим и с малым расходом, а также разгруженность запирающего элемента от давления. The objective of the invention is to improve the accuracy of the device as a shut-off valve, increase the speed of shutting off the flow, the ability to apply the method for flows with high and low consumption, as well as the unloaded pressure of the locking element.
Технический результат достигается тем, что сечение потока перекрывают запирающим элементом, совершающим поступательное движение, соосное с направлением потока, направление потока не меняют, запирающий элемент приводят в действие самим потоком вещества, а для открытия сечения потока совершают внешнее усилие, которое прикладывают к некому возвратному механизму. The technical result is achieved by the fact that the flow cross section is blocked by a locking element that performs translational motion, coaxial with the flow direction, the flow direction is not changed, the locking element is activated by the material flow, and an external force is applied to open the flow cross section, which is applied to some kind of return mechanism .
Повышение точности работы устройства как запирающего клапана, т е достаточно быстрое отсечение потока, достигается тем, что запирающий элемент закрывается со скоростью потока путем воздействия самого потока на запирающий элемент. Обеспечивается быстродействие способа, т к перекрытие происходит со скоростью движения потока в сечении, где находится шляпка запирающего элемента. Способ позволяет масштабировать устройство, реализующее способ, в широких пределах. Способ позволяет осуществлять прерывание потока жидкости при очень крупных расходах жидкости, а также при малых и сверхмалых расходах жидкости. Отсутствует разрушающая разность давлений, которая бы действовала на запирающий элемент.
По совокупности признаков не обнаружен способ прерывания потока жидкости, аналогичный предлагаемому. Improving the accuracy of the device as a shut-off valve, that is, a sufficiently fast cut-off of the flow, is achieved by the fact that the closure element closes at a flow rate by the action of the flow on the closure element. The speed of the method is ensured, since the overlap occurs with the flow velocity in the section where the cap of the locking element is located. The method allows you to scale the device that implements the method, within wide limits. The method allows for the interruption of fluid flow at very large flow rates, as well as at small and ultra-low flow rates. There is no destructive differential pressure that would act on the locking element. By the totality of the signs, a method of interrupting the fluid flow, similar to the proposed one, was not found.
На Фиг. 1 показана принципиальная схема примера реализации устройства для осуществления способа прерывания потока жидкости, содержащего гильзу (1), шляпку (2) шток (З), седло (4), которое имеет переднюю сторону (5) и тыльную сторону (6), прорези (7). In FIG. 1 is a schematic diagram of an example implementation of a device for implementing a method for interrupting a fluid flow comprising a sleeve (1), a cap (2), a stem (3), a saddle (4), which has a front side (5) and a back side (6), slots ( 7).
Раскрытие способа. Запирание потока достигается перекрытием сечения потока запирающим элементом. Направление потока не меняется. Запирающий элемент приводится в действие самим потоком вещества. Для открытия клапана необходимо внешнее усилие, которое прикладывают к некому возвратному механизму. Движения запирающего элемента возвратно-поступательного характера соосны направлению потока. Disclosure of the method. Blocking the flow is achieved by overlapping the flow section with a locking element. The direction of flow does not change. The locking element is driven by the flow of matter. To open the valve, an external force is required, which is applied to some kind of return mechanism. The movements of the reciprocating locking element are aligned with the direction of flow.
