The specific embodiment
For object, technical scheme and advantage that the utility model is implemented are clearer, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, rather than whole embodiment.Below by the embodiment being described with reference to the drawings, be exemplary, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
Fig. 1 is according to the installment state schematic diagram of the blast pipe frock of the utility model one embodiment.Fig. 2 is the installment state schematic diagram at the place, the one end being connected with the exhaust pipe of engine of the frock of blast pipe shown in Fig. 1.Fig. 3 is the local enlarged diagram of the frock of blast pipe shown in Fig. 1.
The frock of blast pipe shown in Fig. 1 comprises blast pipe linkage section 3, the first ring flange 2 and the second ring flange 6.
Blast pipe linkage section 3 extends between first end and the second end, and at blast pipe linkage section, 3 first end end points places have flange 7.Flange 7 stops the axially-movable of the first flange rim blast pipe linkage section, prevents that the first ring flange 2 is from the first end landing of blast pipe linkage section 3.It is pointed out that blast pipe linkage section 3 is not limited to the straight tube shape shown in Fig. 1, crooked blast pipe equally also can meet the demands.But for the ease of the assembling of production and the first ring flange 2, blast pipe linkage section 3 is preferably straight tube.
The first ring flange 2 is enclosed within the outside of blast pipe linkage section 3, and blast pipe linkage section 3 can rotate relatively with the first ring flange 2, is convenient to the first ring flange 2 and the setting angle requirement that meets the different exhaust pipes of engine 1.It is pointed out that and stop that the first ring flange 2 is not limited to the flange 7 shown in figure from the structure of blast pipe linkage section 3 landings, other structure satisfying the demands also can, for example, at the first end of blast pipe linkage section 3, flexible collar is set.
Advantageously, the flange 7 of blast pipe linkage section 3 has chamfering with the side that the first ring flange 2 contacts.On the circumference of the endoporus of the side that the first ring flange 2 contacts with flange 7, also there is chamfering, and the chamfering on the first ring flange 2 and the chamfering on flange 7 cooperatively interact.After the first ring flange 2 compresses, sealing mutually between blast pipe linkage section 3 and the first ring flange 2.
The second end place of blast pipe linkage section 3 has the second ring flange 6, the second ring flanges 6 and is fixed on blast pipe linkage section 3.It is to be noted, if the first ring flange 2 cannot be inserted in from the first end of blast pipe linkage section 3 blast pipe linkage section 3, need so first the first ring flange 2 again the second ring flange 6 to be fixed on to the second end of blast pipe linkage section 3 after the second end of blast pipe linkage section 3 is inserted in.The fixed form of described the second ring flange 6 can be welding, bonding etc.
The shape of the first ring flange 2 and size can be selected flexibly according to the ring flange being mated, such as circular flange dish and prismatic ring flange etc.
Referring to Fig. 2, the first end of blast pipe linkage section 3 is connected with the exhaust pipe of engine 1, and the second end of blast pipe linkage section 3 is connected with engine pedestal blast pipe 5.The first ring flange 2 links together by bolt 4 with the ring flange on the exhaust pipe of engine 1.The number that it is pointed out that bolt 4 is selected according to the number of the bolt hole having on different ring flanges.
It is pointed out that blast pipe frock provided by the utility model can rotate around the axis of blast pipe linkage section 3 the first ring flange 2, adjust its angle, the ring flange that the first ring flange 2 is applicable on the different exhaust pipes of engine 1.But, if the first ring flange 2 does not mate with the model of ring flange on the exhaust pipe of engine 1, need to change blast pipe frock.
The ring flange of the first ring flange 2 on also can engine pedestal blast pipe 5 connects, rotary rowed tracheae linkage section 3 while adjusting the angle of the second ring flange 6 being connected with ring flange on the exhaust pipe of engine 1.
Advantageously, between the first ring flange 2 and connected ring flange, there is pad.The pressure acting on described pad produces distortion after certain numerical value, and fills up uneven place on sealing surface, improves the sealing that flange connects.
The angle of the ring flange that above-mentioned blast pipe frock can be connected with ring flange on the exhaust pipe of engine according to the setting angle adjustment of different engine exhaust tail pipe ring flanges, it is connected with engine exhaust tail pipe, realized the installation requirement that same set of blast pipe frock adapts to different engines, effectively saved cost, be convenient to laboratory blast pipe frock is managed.Meanwhile, above-mentioned the first ring flange is also convenient to staff's installation, has effectively promoted staff's operating efficiency.
Finally it is to be noted: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit.Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
