Inoculation system and method for removing an inoculation nozzle from such an inoculation system

摘要

Inoculation system (10) for a pipe (12) for pressurized gas (48), in particular for compressed natural gas, with (a) an injection point (16) which has (i) an injection nozzle (18) and (ii) a head part (20 ) on which the injection nozzle (18) is supported, characterized in that (b) the injection point (16)(i) has a shut-off valve (24), in particular a ball valve, and (ii) the injection nozzle (18) through the stopcock (24) extends into the tube (12) and extends along a longitudinal axis (L) of the injection site, and that (c) the vaccination system (10) has an injection nozzle extraction device (26) which (i) comprises a frame ( 28) for reversibly securing the inoculation nozzle removal device (26) relative to the inoculation site (16) and (ii) a helical gear (30) having a spindle (34) and a spindle head (36), (iii) wherein the Spindle head (36) is designed to be connected to the head part (20) and to move the head part (20) along the longitudinal axis (L) of the injection points.
