Abstract

Изобретение относится к устройствам для гидравлических трубопроводов. Технический результат заключается в расширении арсенала трубопроводных обратных клапанов, конструкция которых позволяет выполнять ряд дополнительных технологических функций, таких как опорожнение отсекаемого обратным клапаном участка трубопровода, стравливание воздуха на участке подачи рабочего тела, измерение температуры и/или давления с использованием соответствующих устройств, смонтированных непосредственно на корпусе обратного клапана без увеличения монтажной длины трубопровода. Трубопроводный обратный клапан содержит соединенные жестко и герметично первую 1 и вторую 2 детали корпуса, запорный элемент с тарелкой 10 и осевым штоком, имеющим выступающие участки 11, 12, упругий кольцевой уплотнительный элемент 13, жестко закрепленный на одной из сторон центральной тарелки 10, пружину сжатия 14. Первая деталь 1 корпуса выполнена с двумя боковыми патрубками 15, 16, сообщающимися полостями через отверстия 17, 18 с продольным сквозным каналом 2 первой детали 1 корпуса. Вторая деталь 6 корпуса со стороны ее продольного сквозного канала 7, противоположной расположению ее второго участка резьбы 9, выполнена с посадочным торцевым выступом 19 для сопряжения с упругим кольцевым уплотнительным элементом 13, а также с кольцевой канавкой 20 на наружной боковой поверхности и с радиальными отверстиями 21, связывающими полость кольцевой канавки 20 с продольным сквозным каналом 7 второй детали 6 корпуса. Кольцевая канавка 20 располагается напротив отверстия 18 из полости второго бокового патрубка 16. Запорный элемент с тарелкой 10 установлен с возможностью возвратно-поступательногоThe invention relates to devices for hydraulic pipelines. The technical result consists in expanding the arsenal of pipeline check valves, the design of which allows performing a number of additional technological functions, such as emptying the section of the pipeline cut off by the check valve, venting the air at the working fluid supply area, measuring temperature and / or pressure using appropriate devices mounted directly on check valve housing without increasing the pipeline installation length. Pipeline non-return valve contains rigidly and hermetically joined first 1 and second 2 body parts, a locking element with a plate 10 and an axial rod having protruding sections 11, 12, a resilient annular sealing element 13 rigidly fixed on one of the sides of the central plate 10, a compression spring 14. The first part 1 of the housing is made with two side nozzles 15, 16 communicating with cavities through the openings 17, 18 with the longitudinal through channel 2 of the first part 1 of the housing. The second part 6 of the housing from the side of its longitudinal through channel 7, opposite to the location of its second thread section 9, is provided with a fitting end protrusion 19 for mating with an elastic ring sealing element 13, as well as with an annular groove 20 on the outer side surface and with radial holes 21 , connecting the cavity of the annular groove 20 with a longitudinal through channel 7 of the second part 6 of the housing. The annular groove 20 is located opposite the hole 18 from the cavity of the second side nozzle 16. The locking element with the plate 10 is installed with the possibility of reciprocating
