Изобретение относитс к устройствам пневматических и гидравлических средств управлени и может найти широкое применение в машиностроении.The invention relates to pneumatic and hydraulic control devices and can be widely used in mechanical engineering.
Известен преобразователь импульсов с мембранами и дроссел ми в виде просечек на мембране дл демпфировани (задержки) высокочастотных составл ющих сигнала давA known pulse transducer with membranes and throttles in the form of perforations on the membrane for damping (delaying) the high-frequency components of the pressure signal.
лсни 1.Love 1.
Однако в нем не исключена закупорка просечек-дросселей при применении данного устройства на загр зненных средах.However, it does not exclude the blockage of perforated chokes when using this device on polluted media.
Известен преобразователь давлени , содержаш ,ий корпус с упругим элементом, раздел ющим корпус на две камеры и св занным с контактным выходным узлом, клапан и выходной патрубок, подключенный к одной из камер.A pressure transducer is known, comprising a housing with an elastic element dividing the housing into two chambers and connected to a contact outlet unit, a valve and an outlet connected to one of the chambers.
Упругий элемент в известном устройстве выполнен в виде двух диафрагм. В теле шункера , размеш,енного между двум диафрагмами , выполнен расходный канал, в котором подпружинены два обратных клапана 2.The elastic element in the known device is made in the form of two diaphragms. In the body of the bunker, placed between two diaphragms, there is a flow passage in which two non-return valves 2 are spring-loaded.
Известное устройство при условии плотной установки клапанов по отношению к их седлам дл фиксапии утечек давлени среды через уплотнени приводит к инерционности его в работе за счет создании промежуточной камеры, образованной клапанами. Кроме того, в нем увеличены габариты и масса снижена за счет увеличени номенклатуры деталей надежность.The known device, provided that the valves are tightly installed with respect to their seats for fixing the leakage of pressure of the medium through the seals, leads to its inertia in operation by creating an intermediate chamber formed by the valves. In addition, it increases the size and weight by increasing the range of parts reliability.
Цель изобретени - упрощение преобразовател .The purpose of the invention is to simplify the converter.
Поставленна цель достигаетс за счет того, что во входном патрубке выполнен соосный с ним выступ, оголовок которого расположен в горловине упругого элемента иThe goal is achieved due to the fact that in the inlet nozzle there is a protrusion aligned with it, the tip of which is located in the neck of the elastic element and
образует клапан, причем в горловине упругого элемента наход тс отверсти , через которые надклапанна полость сообщена с другой камерой корпуса.it forms a valve, and in the mouth of the elastic element there are openings through which the valve chamber communicates with another chamber of the body.
На чертеже представлена схема предлагаемого преобразовател .The drawing shows the scheme of the proposed Converter.
Преобразователь содержит корпус 1, упругий элемент 2, камеры 3 и 4. Во входном патрубке 5 расположен соосный с ним выступ 6 с оголовком 7. В горловине упругого элемента наход тс отверсти 8, соедин юшие надклапанную полость 9 с камерой 3. Оголовок 7 и горловина упругого элемента образуют клапан. Упругий элемент 2 через плунжер 10 св зан с контактным выходным узлом 11. В плунжере 10 расположен каналThe converter comprises a housing 1, an elastic element 2, chambers 3 and 4. In the inlet pipe 5 there is a protrusion 6 aligned with it with a tip 7. There are holes 8 in the neck of the elastic element, connecting the supravalvale cavity 9 with chamber 3. Head 7 and neck elastic element form a valve. The elastic element 2 through the plunger 10 is connected with the contact output node 11. In the plunger 10 is a channel
