Abstract
The present invention relates to a kind of insulation jacket flanges, it is characterized in that it includes ring flange and welding neck collar, ring flange is sleeved on welding neck collar suit outside, a thermal-insulating type chamber is formed between welding neck collar and ring flange, several thermal insulation medium recirculation holes being connected to thermal-insulating type chamber are uniformly provided on the end face of the upside of ring flange, it is equipped with an intercommunicating pore being connected to thermal-insulating type chamber in welding neck collar lower end, the thermometer hole being connected to thermal-insulating type chamber is equipped in welding neck collar side.The present invention has the advantages that thermal insulation property and effect can be improved.
Description
Technical field
The present invention relates to a kind of jacket flange more particularly to a kind of insulation jacket flanges.
Background technique
Nearly jacket flange, the pipe-line system for needing to keep the temperature；Jacket flange common at present is as shown in Figure 1, collet method
The neck of part is connect with interior instrumentation tubes 2 on orchid 1, and the neck of part and 2 outside of interior instrumentation tubes weld one again on jacket flange 1
Root outer tube 3 injects thermal insulation medium in the jacket space 4 between interior instrumentation tubes 2 and outer tube 3, protects between two jacket flanges
Warm medium is circulated by by-pass line 5, so that the working media temperature in interior instrumentation tubes 2 is maintained within the scope of certain temperature；
But this conventional jacket flange, thermal insulation medium only touch the neck of part on jacket flange, and the maximum flange of area
Disk is with 1.1 part of flange bolt hole, but not in the heat-preserving range of thermal insulation medium, jacket flange 1 forms one in itself
Source of heat release leverages the heat insulation effect of entire pipeline.
Summary of the invention
For disadvantage mentioned above, the purpose of the present invention is to provide a kind of insulation jacket methods that can improve thermal insulation property and effect
It is blue.
Technology contents of the invention are a kind of insulation jacket flange, it is characterized in that it includes ring flange and welding neck collar, flange
Disk is sleeved on welding neck collar suit outside, a thermal-insulating type chamber is formed between welding neck collar and ring flange, at the end of the upside of ring flange
It is uniformly provided with several thermal insulation medium recirculation holes being connected to thermal-insulating type chamber on face, is equipped with one and thermal-insulating type chamber in welding neck collar lower end
The intercommunicating pore of connection is equipped with the thermometer hole being connected to thermal-insulating type chamber in welding neck collar side.
The present invention compared with prior art possessed by advantage are as follows: the present invention devises between ring flange and welding neck collar
Thermal-insulating type chamber improves thermal insulation property and effect；By the intercommunicating pore of welding neck collar rear end, thermal insulation medium is used in pairing
Insulation jacket flange between circulate, it is no longer necessary to additional designs by-pass line is used to thermal insulation medium from this jacket flange
It is transported to another jacket flange, to reduce heat dissipation link, improves heat insulation effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing jacket flange.
Fig. 2 is structural schematic diagram of the invention.
Fig. 3 is use state diagram of the present invention.
Specific embodiment
As shown in Fig. 2, a kind of insulation jacket flange, it is characterized in that it includes ring flange 11 and welding neck collar 12, ring flange 11
It is sleeved on the suit of welding neck collar 12 outside, a thermal-insulating type chamber 13 is formed between welding neck collar 12 and ring flange 11, in ring flange 11
It is uniformly provided with 8 thermal insulation medium recirculation holes 11.1 being connected to thermal-insulating type chamber 13 on the end face of upside, is set in 12 lower end of welding neck collar
There is an intercommunicating pore 12.1 being connected to thermal-insulating type chamber 13, the thermometer hole being connected to thermal-insulating type chamber 13 is equipped in 12 side of welding neck collar
12.2。
The operation principle of the present invention is that as shown in figure 3, the present invention matches use when in use, wherein one in welding neck collar
12.1 two sides of intercommunicating pore of 12 sealing surface are respectively provided with a seal groove, in seal groove be equipped with sealing ring 14, in addition one
12 sealing surface of welding neck collar be plane, the thermal-insulating type chamber 13 between two insulation jacket flanges is connected by intercommunicating pore 12.1；Butt welding
The connecting pin of ring 12 is connect with interior instrumentation tubes 2, and 11 connecting pin of ring flange is connect with outer tube 3, interior instrumentation tubes 2 and interior instrumentation tubes 2
Between jacket space 4 be connected to thermal-insulating type chamber 13 by thermal insulation medium recirculation hole 11.1, thermo detector is set in thermometer hole 12.2.
