专利摘要:
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>

This invention relates to pneumatic automation devices.
Control systems are known that contain a power collector to which the receiver hubs l are connected.
However, in such systems, a slow, smooth supply of supply pressure during their start is impossible, which is necessary for some receiving units.
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.
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.
The aim of the invention is to increase the reliability of the control system.
This goal is achieved by the fact that in a pneumatic power supply device for a control system containing a power collector to which the receiving units of the control system are connected, the input of the power collector is connected to the output of the distributor, which was communicated in its initial state to the atmosphere, the second input the distributor closed in the source state is connected to the output of the start node, and the control chamber of the distributor is connected to the switch-on channel, the input of the start node connected to the power supply is communicated with the output cpl parallel to which
A normally closed valve is turned on, the normally closed valve actuator is made with a spring-loaded piston and a control chamber, and the normally 5 closed valve actuator control chamber is connected to the outlet of the power collector.
FIG. 1 schematically shows the start-up unit, section; in fig. 2 is a schematic diagram of the device.
10 The start node contains a base 1 and a housing 2 rigidly connected to it. The input 3 of the start node is connected to the power supply channel 4 and through the throttle 5 with the output 6 of the start node. Parallel
5, a normally closed valve 7 connected by channels 8 and 9 is connected to the throttle 5.
The drive of the normally closed valve 7 is made with a porchone 10, a spring II and a control chamber 12. . The chamber 13, in which the spring 11 is located, communicates with the atmosphere through the channel 14.
The device (Fig. 2) contains
with a power collector 15 to which the control system receiving nodes 16 are connected. The inlet of the collector 15 is connected to the outlet 17 of the distributor 18. In the initial state, the output 17 is communicated with the first input 19 connected to the atmosphere. The second input 20 of the distributor 18, closed in its initial state, is connected with the output of the start node. The control chamber of the distributor 18 is connected to the switch-on channel 21, and the chamber 12
 control drive normally closed valve 7 through the channels 22 and 23 are connected to the outlet 24 of the collector 15 of the power supply. The start node has
0 an additional input 24 through which it can be controlled by an external signal.
The device works as follows.
5 In the initial position, the collector 15 of the power supply and, accordingly, CC1 of the control 12 is connected to the atmosphere through the first input 19 of the distributor 18. When the signal is applied
0 switching on the channel 21, the valve 18 switches and the power collector 15 is connected to the power supply channel 4. via the choke S. through the valve 7 with a large flow area, the power collector 15 is connected to the feed channel 4.
Thus, the device provides a slow increase in pressure in the supply manifold when it is turned on and the rapid discharge of air into the atmosphere when the device is turned off.
