Abstract

A progressive pneumatic starter device 1 has a permanently connected throttle path between its inlet 15 and its outlet 8 and, in parallel, a longer diameter path controlled by a distributor or member 3 which is biased by spring 28 to a position interrupting this path and moved to its open position by pressure applied at 10 and through control channel 29 to move piston 27 against the force of spring 28. The starter device is advantageously placed upstream of a pneumatic switching means 38 (controlling a plurality of rams) to which it is directly associated for the purpose of shortening its channels for transfer of fluid. A pneumatic threshold relay valve (67), Fig. 5, (not shown) may be placed between the control line inlet 10 and point 61. <IMAGE>

Изобретение относитс  к устройствам пневмоавтоматики.This invention relates to pneumatic automation devices.

Известны системы управлени , содержащие коллектор питани , к которому подключены приемные узды l.Control systems are known that contain a power collector to which the receiver hubs l are connected.

Однако в таких системах невозможна медленна  плавна  подача давлени  питани  при их пуске, что бывает необходимо дл  некоторых приемных узлов.However, in such systems, a slow, smooth supply of supply pressure during their start is impossible, which is necessary for some receiving units.

Наиболее близким к изобретению по технической С5пцности  вл етс  устройство, содержащее узел пуска, вход которого, соединенный с каналом питани , сообщен с выходом через дроссель, параллельно которому включен нормально закрытый клапан, причем привод нормально закрытого клапана выполнен с подпружиненным поршнем и с камерой управлени , соединенной с выходсж узла пуска. При этом вход коллектора питани  соединен с выходом распределител , сообщенным в исходнсж состо нии с его первьвм входом, подключенным к атмосфере, втСлррй заход распределител , закЕ«1ТЫй в исходном состо нии, св зан с выходом узла пуска, а кс1мера управлени  распределител  - с каналом включени  2J .The closest to the invention in technical terms is a device comprising a start unit, the inlet of which, connected to the supply channel, communicates with the outlet through a throttle, in parallel with which a normally closed valve is connected, the normally closed valve is driven by a spring-loaded piston and connected to the start node. In this case, the input of the power collector is connected to the output of the distributor, which was communicated in its initial state with its first input connected to the atmosphere, during which the distributor’s start, connected with the start node, was connected to the distributor control channel. switch on 2J.

Недостатком известного устройства  вл етс  следующее. При закрытом первом входе распределител  давление на выходе узла пуска быстро нарастает, и срабатывает привод нормально зак мтого клапана, через который канал питани  соедин етс  с выходом узла пуска. При соединении первого входа распределител  с его выходом в первый момент происходит йлстра  подача давлени  питани  в коллектор, что может привести к выходу из стро  приемных узлов. При включении распределител  перед известньш: узлом пуска исключаетс  возможность Настрого сброса давлени  из коллектора питани .A disadvantage of the known device is the following. When the first inlet distributor is closed, the pressure at the outlet of the start-up assembly rapidly increases, and the drive of the normally closed valve is actuated through which the supply channel is connected to the output of the start-up assembly. When the first inlet of the distributor is connected to its outlet, at the first moment, the pressure supply pressure to the collector occurs, which can lead to failure of the receiving units. When the distributor is turned on in front of the well-known: the start-up unit, the possibility of a pressure relief from the supply manifold is eliminated.

Целью изобретени   вл етс  повышение надежности системы управлени .The aim of the invention is to increase the reliability of the control system.
