Изобретение относитс  к средствам регулировани  параметров пара, в которых примен ют редукционные клапаны.The invention relates to steam control means in which pressure reducing valves are used.

Известны регул торы параметров пара, содержащие регулирующий орган, кинематически св занный с мембраной, одна полость которой подключена к замкнутой ел кости , а друга  через соединительную тру- ; бку - к полости выхлопного патрубка. .Steam parameter controllers are known that contain a regulator, kinematically connected with a membrane, one cavity of which is connected to a closed firmer, and the other through a connecting pipe; BKU - to the cavity of the exhaust pipe. .

Однако в таких регул торах затруднена коктенсапи  стагизма объекта регулиров ни . .; .-..-.However, in such regulators, the coensensi of stagism of the object of regulation is difficult. ; .-..-

Цель изобретени  - компенсаци  стати; ма объекта регулировани .The purpose of the invention is to compensate for the article; ma object of regulation.

Дл  этого свободный конец соединительной трубки разметен внутри эжектора, установленного в полости выхлопного патрубка и снабженного винтом аксиального перем& шени .To this end, the free end of the connecting tube is spaced inside the ejector, installed in the cavity of the exhaust pipe and equipped with an axial screw & sheney.

На чертеже показан предложенный регу- л тор.The drawing shows the proposed controller.

Пар, например, дл  подачи в стациокар;ный теплообменник поступает во входной стшсан 1. В этом стакане выполнены о-пв0|Кти  экспоненциальной формы, частично j Steam, for example, for supplying to the stationary car; a new heat exchanger enters the inlet section 1. In this glass, o-pv0 | Kti are of exponential form, partially j

(Перекрываемые регулирующей втулкой 2, кинематически св занной вилкой 3 и што- -:ком 4 с мембраной 5, -перемещающей втулку 2 относительно стакана 1 при нэ:менении перепада давлений в полост х мембраны .(Overlapped by regulating bushing 2, kinematically connected fork 3 and stock-: lump 4 with membrane 5, -transfering sleeve 2 relative to cup 1 when ne: the change in pressure difference in the membrane cavities.

: Одна полость мембраны 5 подключена |к замкнутой емкости 6. Перегородка 7: с ;двойными стенками и шайбой 8 обеспечивает изол цию другой полости мембраны ОТ потока греющего пара. Эта полость пооключена к полости выхлопного патрубка 9 черезсоедини-гельную. трубку 10, свободный конец которой; р(азм&шен внутри эжев. ;тора 11. Тем caMibiM осуществл етс  по/ вод давлени  обратной св зи, к мембра :ному серводвигателю. : Дл  изменени  настройки регул тора {Необходимо вывинтить фиксирующий винт 12, вставить в гнездо приводной винт так, iчтобы его край вошел в один из пазов на наружной поверхности эжектора 11, и пере .местить эжектс/ - в аксильном направлении I на нужную величину.: One cavity of the membrane 5 is connected | to a closed container 6. The partition 7: with; double walls and a washer 8 provides isolation of the other cavity of the membrane FROM the heating steam flow. This cavity is connected to the cavity of the exhaust pipe 9 through the connecting-gel. tube 10, the free end of which; p (dimension & inside ejev.; torus 11. Meanwhile caMibiM is carried out via feedback water pressure / to the diaphragm: th servo motor.: To change the setting of the regulator {It is necessary to unscrew the fixing screw 12, insert the drive screw so To make the edge enter one of the grooves on the outer surface of the ejector 11, and to move the eject / / in the axial direction I by the desired value.

Емкость 6 соелине а через дроссель 13 с дополнительной емкостью 14, что обеспечивает интегрирующие свойства регул тора в переходном процессе. Штуцер 15 прехьнаэначен дл  удалени  конденсата.Capacity 6 is connected through a choke 13 with an additional capacity of 14, which provides the integrating properties of the regulator in the transient process. The nozzle 15 is designed to remove condensate.
