Description

Регул торы давлени  рабочей среды , заключающие в себе клапан, управл емый расположенной за ним мембраной, )/же известны. Дл  использовани  подобного регул тора в качестве автоматического прерывател  рабочей среды в случае аварии или при чрезмерном расходе рабочей среды, сопровождающемс  снижением давлени  в отвод щей сети, согласно изобретению, предусматриваетс  применение второго седла, расположенного передклапаном со стороны подвода рабочей среды.Regulators of pressure of the working medium, containing a valve controlled by a membrane located behind it, are known. To use such a regulator as an automatic interrupter of the working environment in the event of an accident or when the working environment is excessively consumed, accompanied by a decrease in pressure in the discharge network, according to the invention, a second seat is provided that is located on the front side of the valve.

На чертеже изображен предлагаемый регул тор давлени  в разрезе.The figure shows the sectional pressure regulator according to the invention.

Корпус 7 регул тора снабжен штуцерами 2 и J дл  подвода и отвода рабочей среды. Рабочие полости 4 и 5 сообщены каналом 6, перекрываемым клапаном 7. Шток 8 посредством втзлки 9 соединен с мембраной 10, зажатой между фланцами корпуса 7 и колпачка 77. Полость 72 над мембраной сообщена с полостью 5 каналом ТЗ шайбы 14. Мембрана 10 нагружена пружиной 15, регулируемой винтом 16.The regulator housing 7 is equipped with fittings 2 and J for supplying and discharging the working medium. The working cavities 4 and 5 are communicated by a channel 6 overlapped by a valve 7. The rod 8 is connected by means of the inlet 9 to a membrane 10 sandwiched between the flanges of the housing 7 and the cap 77. The cavity 72 above the membrane is connected to the cavity 5 by the channel TZ of the washer 14 adjustable screw 16.

В полости 4 установлена втулка 17 с седлом 18, перекрываемым тоже клапаном 7.In the cavity 4, a sleeve 17 with a seat 18 is installed, which is also blocked by a valve 7.

при повышении давлени  рабочей среды за клапаном 7 мембрана 10 регул тора прогибаетс  вниз и увлекает за собой клапан 7. Последний перекрывает канал 6, в результате чего давление после регул тора снова выравниваетс  до заданной величины . При понижении давлени  происходит обратное  вление.with increasing pressure of the medium behind the valve 7, the membrane 10 of the regulator bends downwards and entrains the valve 7. The latter closes the channel 6, as a result of which the pressure after the regulator is equalized again to a predetermined value. With decreasing pressure, the opposite occurs.

В случае аварии, например при разрыве трубопровода, а также при чрезмерном расходе рабочей среды давление за клапаном падает настолько сильно, что клапан 7 пружиной 15 плотно прижимаетс  к седлу 18, полностью прекраща  поступление рабочей среды в линию.In the event of an accident, for example, when the pipeline is broken, and also when the flow medium is excessively consumed, the pressure downstream of the valve drops so much that the valve 7 is pressed tightly against the seat 18 by the spring 15, completely stopping the flow of the flow medium to the line.

После устранени  аварии клапан 7 отвод т от седла 18 вручную путем нажати  на шток 19 и преодолени  сопротивлени  пружин 15 и 20.After elimination of the accident, the valve 7 is retracted from the seat 18 manually by pressing the rod 19 and overcoming the resistance of the springs 15 and 20.

Предмет изобретени Subject invention

Регул тор давлени , заключающий в себе клапан, управл емый расположенной за ним мембраной, о т ли чающийс  применением второго седла, расположенного перед клапаном со стороны подвода рабочей среды.A pressure regulator incorporating a valve, controlled by a membrane located behind it, is used by a second seat, located in front of the valve on the supply side of the working medium.
