Abstract
The utility model discloses a kind of novel hazardous gas transporting system double-bushing pipeline adpting flange, from being provided with outer platform region, halfpace region and interior siphunculus successively outside to inside in described adpting flange main body, halfpace region is provided with vent, described vent is provided with 2 ~ 4 and is circularly and evenly distributed on halfpace region, described vent is arc long lumbar hole, and adjacent vent holes interval radian is 20 ° ~ 30 °.Due to 2 ~ 4 vents that are circularly and evenly distributed in circular halfpace region, the shape of vent is arc long lumbar hole, instead of the circular intermediate throughholes of existing annular array, adds the available ventilation area of flange intermediate throughholes.
Description
Technical field
The utility model relates to a kind of adpting flange, particularly relates to a kind of novel hazardous gas transporting system double-bushing pipeline adpting flange.
Background technique
Take LNG as the boats and ships of fuel, cabin is designed according to essential safe type usually, fuel gas pipeline in specification, laws and regulations requirement essential safe type cabin adopts double wall pipe, is full of pressure and ventilates higher than the inert gas of gas fuel pressure or by specification relevant requirements between inner and outer tubes.
Chinese patent 201410826289.2 discloses a kind of hazardous gas transporting system double-bushing pipeline adpting flange, comprise the adpting flange main body of two hollow ring structures, from being provided with outer tube join domain successively outside to inside in adpting flange main body, transition region and interior pipe join domain, transition region is evenly provided with some vents, outer tube join domain is provided with the outer tube shoulder of circle structure, interior pipe join domain is provided with the interior tube shoulder of circle structure, interior tube shoulder and outer tube shoulder are arranged in the same way, apply this adpting flange design burning line, outer tube can adopt conventional seamless steel pipe peculiar to vessel, outer tube specification only need be larger than interior pipe 1 ~ 2 grade, greatly can reduce hazardous gas transporting system pipeline integrity boundary dimension, be reduced to the discharge capacity of double wall pipe negative pressure machinery induced draft fans, exhaust column caliber, ensure that the ventilation continuity between double wall pipe, interior, pipe all passes through above-mentioned Flange joint, conveniently builds construction, improves efficiency of construction.This technological scheme arranges a circle intermediate throughholes on flange, keeps the space UNICOM between inner and outer pipe, realizes the available ventilation of code requirement.The drawback that this kind of form exists is mainly: 1. flange intermediate throughholes diameter is little, and available ventilation area is less; 2. when two adpting flanges utilize bolt to connect, easily there is relatively large deviation in intermediate throughholes concentricity, can greatly reduce the available ventilation area of through hole.
Model utility content
In view of the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of novel hazardous gas transporting system double-bushing pipeline adpting flange, for problems such as available ventilation area is little between pipe, outer tube in solving in prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of novel hazardous gas transporting system double-bushing pipeline adpting flange, from being provided with outer platform region, halfpace region and interior siphunculus successively outside to inside in described adpting flange main body, halfpace region is provided with vent, described vent is provided with 2 ~ 4, and being circularly and evenly distributed on halfpace region, described vent is arc long lumbar hole, and adjacent vent holes interval radian is 20 ° ~ 30 °.
As preferably, vent is provided with 3.
As preferably, adjacent vent holes interval radian is 20 °.
As preferably, each vent size is equal.
As preferably, with the flange connection surface of flange main body for benchmark, described interior siphunculus is higher than described halfpace region, described halfpace region is higher than described outer platform region, described outer platform region is connected convex shoulder with halfpace region by outer tube and connects, and halfpace region is connected convex shoulder with interior siphunculus by interior pipe and connects.
As preferably, outer platform region is circularly and evenly distributed attachment hole.
As mentioned above, novel hazardous gas transporting system double-bushing pipeline adpting flange of the present utility model, interior pipe connects convex shoulder by interior pipe and is connected with flange welding; Larger than interior pipe 1 ~ 2 grade of outer tube specification, outer tube connects convex shoulder by outer tube and is connected with flange welding.Keep the space UNICOM between inner and outer pipe by vent, realize the available ventilation of code requirement.
Novel hazardous gas transporting system double-bushing pipeline adpting flange of the present utility model also has following beneficial effect:
Due to 2 ~ 4 vents that are circularly and evenly distributed in circular halfpace region, the shape of vent is arc long lumbar hole, instead of the circular intermediate throughholes of existing annular array, adds the available ventilation area of flange intermediate throughholes.When two adpting flanges utilize bolt connection concentricity to occur deviation, the available ventilation area effect for intermediate throughholes is less, and practical effect is better.

Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
In order to can the utility model be described in detail, first, next adpting flange of the present utility model is illustrated:
With reference to the accompanying drawings shown in 1,2, a kind of novel hazardous gas transporting system double-bushing pipeline adpting flange, from being provided with outer platform region 1, halfpace region 2 and interior siphunculus 3 successively outside to inside in adpting flange main body, outer platform region 1 is circularly and evenly distributed attachment hole 4, and halfpace region 2 is provided with annular recess 5 around interior siphunculus 3.With the flange connection surface on the right side of flange main body for benchmark, interior siphunculus 3 is higher than halfpace region 2, halfpace region 2 is higher than outer platform region 1, outer platform region 1 is connected convex shoulder 6 with halfpace region 2 by outer tube and connects, and halfpace region 2 is connected convex shoulder 7 with interior siphunculus 3 by interior pipe and connects.Wherein, the interior pipe of double-jacket tube is welded on interior pipe and connects on convex shoulder 7, and the outer tube of double-jacket tube is welded on outer tube and connects on convex shoulder 6.
