Auxiliary pressure-controlled valve device for use as controlled pressure reducer in system for guiding natural gas, has bypass valve with entrance and exit for fluid, where entrance and exit are connected with switched channel

摘要

#CMT# #/CMT# The auxiliary pressure-controlled valve device (10) has a bypass valve (20) with an entrance (22) and an exit (24) for fluid. The entrance and the exit are connected with a switched channel (30). A pilot valve (60) is attached at a control entrance (42). A connection (64) is connected with the exit of the bypass valve and another connection (66) is connected with the entrance of the bypass valve by a measuring line (50). A flow channel (70) is provided in the pilot valve, which connects the control entrance of the bypass valve with a downstream side (44) of the bypass valve. #CMT#USE : #/CMT# Auxiliary pressure-controlled valve device for use as a controlled pressure reducer in a system for guiding natural gas to a connection by transport or distribution system. #CMT#ADVANTAGE : #/CMT# The auxiliary pressure-controlled valve device has a bypass valve with an entrance and an exit for fluid, where the entrance and the exit are connected with a switched channel, and hence ensures fast, energy saving, simple construction and easy maintenance of the auxiliary pressure-controlled valve device with accurate pressure actuation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an auxiliary pressure-controlled valve device. 10 : Auxiliary pressure-controlled valve device 20 : Bypass valve 22 : Entrance 24 : Exit 30 : Switched channel 42 : Control entrance 44 : Downstream side 50 : Measuring line 60 : Pilot valve 64,66 : Connections 70 : Flow channel.
