Abstract
The utility model discloses a gas pressure regulating box import and export coupling joint mainly has pressure regulating box inlet and outlet pipe, arranges the mounting flange at top in the import in, arranges the welding circular bead at import and export lower top in, and the sealing washer of arranging the welding flange terminal surface in is constituteed with the movable flange that welding flange matches. When the movable flange is installed, the fixed flange is installed firstly, then the movable flange is rotated to be aligned to the bolt installation hole of the flange matched with the movable flange, and a bolt is penetrated and screwed, so that the movable flange is very convenient to assemble and disassemble.
Description
Technical field
The utility model relates to the pressure-regulating box of city gas transmission pipeline network corollary equipment and imports and exports connecting joint, belongs to equipment mounting technique field.
Background technique
City gas is carried the Placement of corollary equipment major loop and pressure-regulating box, district or voltage regulating station at present, mainly contains two kinds of forms, and a kind of is that flange connects, and another kind is to be threaded.Two kinds of multi-form being connected processing and assembling, cost control, maintaining and preventing that the dielectric leakage method from all having different difference.The general pressure governor that is threaded, volume is little, cost is low, uses more general under the working condition condition of low pressure small flow.But maintaining is difficulty comparatively, in case go wrong, will integral body tears open greatly greatly and unloads, and can not fix a breakdown at short notice, but because it is with low cost, and the volume small occupied space is little, therefore use more.Flange connects that to have an assembling quick, easy to maintenance, leak-proof good, adapts to the pressure range broad, especially uses the most general at the big flow neck of mesohigh.But its pipeline flange is in when welding, the check and correction difficulty in construction bolt hole, go up behind the welding forming lower flange when mounted bolt hole Chang Buneng well aim at, cause and difficulty is installed even does over again.
The content of model utility
At the problems referred to above, the utility model provides a kind of quick-detach soon, can play the import and export connecting joint of combustion gas pressure-regulating box, district or the pressure regulation platform of leakproof effect again.
The utility model is that pressure-regulating box, regional voltage regulating station import and export connecting joint, comprise pressure-regulating box import and export pipe, place the fastening flange of import upper top, place the welding shoulder of importing and exporting the next top, the loose flange that matches with welded flange places the seal ring of welded flange end face to form.It is characterized in that loose flange is enclosed within the import and export pipe
Welding
Fastening flange rotates the bolt mounting holes that loose flange is aimed at the flange that matches with it then, penetrates bolt and tightens and get final product, and installs and removes very convenient.
Described loose flange 1 places between fastening flange 5 and the welding shoulder 2, imports and exports on the cylindrical of pipe, cooperates and can relatively rotate with the welding shoulder.
Described welding shoulder 2 places the lower end of importing and exporting pipe, is provided with in the middle of the shoulder end face and the seal ring groove that is complementary.
Also be provided with the bolt mounting holes that is complementary with companion flange on the described loose flange 1.With the interior step that is complementary of welding shoulder.
The utility model is reasonable in design, and compact structure is installed and removed pressure-regulating box fast, owing to be provided with special-purpose seal ring, has effectively played the leakproof effect, and installs simply, and maintaining is convenient, has practicability widely.
Description of drawings
Accompanying drawing 1 is that overall structure master of the present utility model looks sectional view;
Accompanying drawing 2 is partial sectional views of the present utility model.
The 1-loose flange, 2-welds shoulder, the 3-seal ring, 4-imports and exports pipe, the 5-fastening flange
Embodiment
Below in conjunction with example the utility model is further described:
The utility model welds shoulder 2 mainly by loose flange 1, and seal ring 3 is imported and exported pipe 4, and fastening flange 5 constitutes.
Fastening flange 5 is welded on the last top of importing and exporting pipe 4, welding shoulder 2 places the lower end of importing and exporting pipe 4, loose flange 1 places between fastening flange 5 and the welding shoulder 2, import and export on the cylindrical of pipe, cooperate and to relatively rotate with the welding shoulder, during installation, rotate loose flange 1 and aim at the bolt mounting holes of the flange that matches with it and tight a bolt and get final product.
Claims (4)
