Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 4, an air inlet pipeline assembly of a combustor comprises a pipeline main body 1, wherein the pipeline main body 1 is provided with a first connector 2 and a second connector 3, the orientations of the first connector 2 and the second connector 3 are located on different planes, a straight pipe flaring nut 4 is sleeved on the first connector 2, and the inner wall of the straight pipe flaring nut 4 is sequentially provided with a smooth section 5, a threaded section 6 and a frosted section 7 from front to back;

second interface 3 on the cover be equipped with elbow fitting 8, still include a combustor stationary blade 9, combustor stationary blade 9 seted up connecting hole 10 and fixed orifices 11, elbow fitting 8 keeps away from the one end of pipeline main part 1 and is equipped with protruding portion 12, protruding portion 12 insert extremely connecting hole 10 in, protruding portion 12 on still be equipped with round recess 13, recess 13 in inlay and be equipped with jump ring 14, jump ring 14 will combustor

stationary blade

9 and 8 chucking of elbow fitting be in the same place.

Because the inside diameters of the straight pipe flaring nuts 4 are different, the screwing depth is difficult to master when the external pipe fitting is screwed in, and the situation of over-looseness or over-tightness is easy to occur, so that the normal use is influenced. Through smooth section 5, threaded section 6 and dull polish section 7's setting for the user can judge the wrong income degree of depth according to the sound of sending when screwing in, and the sound is not produced or the sharp-pointed sound that can send the metal friction when external pipe fitting contacts 5 with smooth section, and what send when external pipe fitting contacts 6 with threaded section is the sound when normal screw thread is screwed up, can send husky sound when external pipe fitting contacts 7 with dull polish section. Therefore, the user can easily distinguish the use, and the user recommends stopping screwing in as soon as the user hears the sand sound, and the screwing-in depth can ensure good use effect.

Because the combustor size on the market is different, the user purchases the use according to self demand preferred, and conventional air inlet pipeline specification is single, and the accessory is rare, often finds not the adaptation with the combustor when using, needs the time to go to purchase the accessory that matches again, and is very inconvenient. The utility model provides a combustor stationary blade 9 that can be applicable to different combustors is provided in this embodiment, specifically, combustor stationary blade 9 on be equipped with connecting hole 10 and the fixed orifices 11 of a plurality of different diameters, through the setting of the connecting hole 10 of different diameters for this combustor stationary blade 9 can the more interface of air inlet pipe of adaptation, simultaneously through the setting of the fixed orifices 11 of different diameters, can make combustor stationary blade 9 fix to combustor or other fixed areas better on.

Because spare part is more in the assembly, under the condition that lacks good spacing effect, single personnel utilize both hands probably to lose one another, lead to the condition that the part scatters and falls to take place, cause the inconvenient condition of assembly. In this embodiment, the end of the elbow joint 8 away from the pipe body 1 is rectangular, the upper edge of the burner fixing plate 9 extends to one side to form a limiting portion 15, and when the protruding portion 12 is inserted into the connecting hole 10, the limiting portion 15 abuts against the upper end face of the end of the elbow joint 8 away from the pipe body 1 to form a limiting fit. Adopt the scheme of this embodiment, during the operation, with spacing portion 15 with keep away from the up end butt spacing of the one end of pipeline main part 1 to operating personnel can let out combustor stationary blade 9, releases an operative employee hand, carries out other operations and utilizes the set screw to fix both.

In this embodiment, a sealing groove is formed in the end face of the straight pipe flaring nut 4, which is far away from one end of the pipeline main body 1, and a sealing ring 16 is embedded in the sealing groove. When the straight pipe flaring nut is used, one end of the straight pipe flaring nut 4 is connected with the pipeline main body 1, and the other end of the straight pipe flaring nut needs to be externally connected with other components, so that the connection stability and the connection tightness can be improved through the arrangement of the sealing ring 16.

In this embodiment, the first interface 2 is a bowl-shaped interface, the straight pipe flaring nut 4 is provided with a third interface 17 adapted to the bowl-shaped interface, the third interface 17 further extends outward to form a crimping part 18, the pipeline main body 1 is sleeved with a soft sealing gasket 19 near the bowl-shaped interface, after the straight pipe flaring nut 4 is sleeved into the pipeline main body 1, the third interface 17 abuts against the bowl-shaped interface, and the crimping part 18 is crimped on the soft sealing gasket 19 of the pipeline main body 1 to form sealing connection. Firstly, the arrangement of the bowl-shaped connector can ensure that the gas inlet and outlet of the pipeline main body 1 are smoother; and, straight tube flaring nut 4 is realized being connected fixedly through the mode of butt and first interface 2, and this mode is very convenient when the production assembly, can promote production efficiency greatly, realizes the sealed effect of fastening through soft sealing pad 19 simultaneously after the assembly. And after the straight pipe flaring nut 4 is installed, the second interface 3 of the pipeline main body 1 and the elbow joint 8 are fixed together by welding.

In this embodiment, the pipeline body 1 is plated with a tin layer. Because the required transport gas of combustor or combustion-supporting gas have certain corrosivity, through the setting of tin layer, can effectively protect pipeline main part 1 not corroded increase of service life, and prevent that harmful metal from flowing into in the circulation liquid.

The utility model discloses during production assembly, embolia straight tube flaring nut 4 from 3 departments of second interface earlier, after that along pipeline main part 1 rebound with straight tube flaring nut 4 for third interface 17 and the butt joint of 2 adaptations of first interface, crimping portion 18 tightly pushes down the soft sealing pad 19 simultaneously, realizes fastening and sealed effect, then is fixed with elbow fitting 8's one end and pipeline main part 1's second interface 3, and welded fastening's mode is preferably taken.

The utility model discloses during the use, the port that aims at elbow fitting 8 with connecting hole 10 of combustor stationary blade 9 embolias, and realize limiting displacement through spacing portion 15 and elbow fitting 8, so that the user vacates the one hand and carries out other operations, go into recess 13 with jump ring 14 card again, realize the preinstallation of combustor stationary blade 9, utilize the cooperation of fixed screw and fixed orifices 11 to fix combustor stationary blade 9 and combustor or other stationary planes together, thereby realize holistic fixed action, at last will connect the pipe fitting outward respectively with elbow fitting 8 and straight tube flaring nut 4 and be connected, realize holistic tube coupling.
