Description
(1) technical field
The utility model relates to urban operating mechanism field, particularly fixed knot inside and outside a kind of direct embedment steel steam pipe with steel jacket.
(2) background technique
Current, the steel-sleeve steel steam directly-buried thermal insulation pipes outer slip insulating structure form using steel pipe as outer pillar obtains in field of thermal insulation to be applied more widely.The high temperature of medium >=300 DEG C because the flowing medium of its conveying is high-temperature steam, and directly to contact with working steel tube, so can cause the axial direction heated distortion of working steel tube; And when heat is delivered to external protective steel tube by working steel tube and thermal insulating material, temperature declines very large, external protective steel tube surface temperature only has < 50 DEG C, causes the axial deformation of outer pillar relatively little at this temperature.In order to reduce the gap of axial deflection between outer steel pipe and working steel tube, and reducing the hot internal stress of working steel tube, generally taking in industry compensator is installed and coordinating the mode of Internally fixed node or extenal fixation joint to carry out.And current inside and outside fixed knot complex manufacturing, cost of material is too high, especially for the superheated vapor of medium temperature within 300 DEG C.
(3) summary of the invention
The utility model is in order to make up the defect of prior art, provide a kind of making simple, cost is lower, fixed knot inside and outside the direct embedment steel steam pipe with steel jacket being applicable to the operating mode of medium temperature≤300 DEG C, the internal stress that it effectively can solve working steel tube can not effectively discharge or the problem of radial misalignments easily occurs working steel tube relative external protective steel tube, eliminates the impact of piping thermal prestressed on pipe network general safety.
The utility model is achieved by the following technical solution:
Fixed knot inside and outside a kind of direct embedment steel steam pipe with steel jacket, comprise working steel tube, it is characterized in that, described working steel tube be circumferentially with 3 to 12 pieces in the uniform inner support plate of radioactivity, the shaft axis of described inner support plate and working steel tube is positioned at same plane, and described inner support plate has breach, and described working steel tube overcoat has the thrust ring flat-plate of concentric, described Thrust ring board is in breach, and thrust ring flat-plate is positioned at the neutral position of working steel tube; Described working steel tube overcoat has two sections of identical external protective steel tubes, and two sections of external protective steel tubes and working steel tube concentric are also respectively in thrust ring flat-plate both sides, and the external protective steel tube of described thrust ring flat-plate both sides is provided with the some reinforcement gussets uniform in radioactivity; Inorganic heat insulation material is filled with between described working steel tube and external protective steel tube; External protective steel tube is provided with humidity discharging pipe, and be provided with the outer pillar of humidity discharging outside humidity discharging pipe, external protective steel tube outer surface is coated with anticorrosive coat.
Described inner support plate has 8 pieces.
The beneficial effects of the utility model are:
1, the utility model is provided with thrust ring flat-plate, and be connected with working steel tube by inner support frame, inner support frame interval 150mm, with working steel tube firm welding, thrust ring flat-plate and external protective steel tube vertical welding, and be provided with bearing diagonal reinforcing, due to thrust ring flat-plate and external protective steel tube firm welding, therefore this structure can limit working steel tube relative to external protective steel tube generation radial misalignments and axially displaced, eliminates the impaired insulation failure problem caused of thermal insulating material.Simultaneously due to inner support frame and the little area of contact of Thrust ring plate, cut off the heat transfer path of external protective steel tube and working steel tube.In addition, thrust ring flat-plate can by the internal stress of working steel tube by inner support frame be delivered to external protective steel tube and the fixed knot matched on, absorb working steel tube stress, thus significantly weakened working pipe stress.
2, the utility model solves that cost of production is high, the bottleneck problem of complex manufacturing, the internal stress that simultaneously can solve again working steel tube reliably can not discharge in time or working steel tube mutually externally pillar easily there is the problem of radial misalignments, eliminate the impact of piping thermal prestressed on pipe network general safety.
(4) accompanying drawing explanation
