Abstract
The utility model discloses a prevent static metal collapsible tube belongs to the metal pipeline field. The utility model provides a ring flange passes through connecting bolt fixed connection, still is equipped with the cross-over connection wire on the connecting bolt, and the annular joint of cross-over connection wire, clamp shape connect respectively hug closely on the connection terminal surface lateral wall of two ring flanges, because the utility model discloses the length adjustable of preventing static cross-over connection area between well annular joint, the clamp shape connects, consequently, can be applicable to the wire cross-over connection of the ring flange of different thickness.
Description
Technical Field
The utility model relates to a metal pipeline field, concretely relates to prevent static metal collapsible tube.
Background
Generally, the flange connection is poor in conductivity of two flanges due to the fact that gaskets are not electrified and bolts can rust, so that static electricity can flow off in a bridging mode, static electricity can be gathered to generate static sparks, natural gas belongs to flammable and explosive gas, and the fact that the static electricity is introduced to the ground is necessary. According to the related standard of whether the metal pipeline flange is in anti-static grounding bridging or not, the anti-static bridging is required in two modes: one is by measuring the resistance value, when the resistance value between flanges exceeds 0.03 omega, a wire is needed to be connected in a bridging way; another is that when the number of the connecting bolts of the flange is less than five, the lead is needed to be bridged. The wire jumper structure in the prior art is simple, nuts at two ends need to be moved when the wire jumper is mounted and dismounted, and the length of the jumper cannot be adjusted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent static metal collapsible tube with adjustable cross-over connection wire.
The technical scheme of the utility model is that: an anti-static metal hose comprises a telescopic pipe, a corrugated pipe and an inner net sleeve, wherein the corrugated pipe sleeve is arranged on the outer ring of the inner net sleeve, the telescopic pipe is arranged on the outer ring of the corrugated pipe, the telescopic pipe, the corrugated pipe and the inner net sleeve are fixedly connected with connecting pipes arranged at two ends through welding, the port part of the connecting pipe is connected with a matched flange in a sealing way, the flanges between the adjacent metal hoses are fixedly connected through connecting bolts, two ends of each connecting bolt are also provided with a cross-over lead, each cross-over lead comprises an annular joint and a hoop-shaped joint which are connected through an anti-static cross-over belt, each hoop-shaped joint comprises a first fixing ring and a second fixing ring which are rotatably connected through a pin shaft, one ends of the first fixing ring and the second fixing rings, which are far away from the pin shaft, are respectively provided with a connecting, the other end of the connecting lug plate is connected to the metal ground plate after bypassing the through hole, external threads are arranged above the through hole of the connecting lug plate, and the connecting lug plates of the first fixing ring and the second fixing ring are locked through nuts.
According to the technical scheme, the annular joint is sleeved on the connecting bolt and tightly attached to the outer side wall of the connecting end face of one flange plate through the nut, and the clamp-shaped joint is sleeved on the connecting bolt and attached to the outer side wall of the connecting end face of the other flange plate.
The utility model has the advantages that:
the utility model provides a dismantle convenient cross-over connection wire, a connecting end of cross-over connection wire is the clamp shape and connects, can direct suit on connecting bolt to hug closely ring flange lateral wall locking on the bolt through the nut that the clamp shape connects, the length of the antistatic cross-over connection area of bypassing the clamp shape and connecting can be adjusted, thereby is applicable to the ring flange connection of different thickness.
