Pomocí ventilu PUSH obr.14 je velmi snadné 
zavést kontrolní tlak do hlavy 11° zkontrolovat 
nastavení vypínacích tlak

ů

 na vzestup a pokles. 

If the pressure Pa drops below the set-point, the sup-
port  of  spring  16  stops  its  stroke  on  the  beat  of  the 
body  5  and  the  spring  15  displaces  the  support  17 
upwards and the shaft 18 as a result. The cam 24 then 
shifts the feeler 19 and causes the release of the lever 
mechanism 20.

 

Intervention of the slam-shut  device can also be pro-
voked manually by means of the release button 22. The 
connection  between  the  control  head  11  and  the  Pa 
control  point  can  be  made  with  the  interposition  of  a 
device (Push) fig. 14 which makes it easy to control the 
operation of the pressure control device.
