Description
Technical field
The utility model is related to pipeline valve technical field, in particular to a kind of extension flange structure.
Background technology
Flange connection refers to：Two pipelines, pipe fitting or equipment, first it is individually fixed on a ring flange, then two
Add flange gasket between individual ring flange, finally with bolt by the tension of two ring flanges make that it combines closely a kind of detachable
Joint.Because flange and pipeline are to be fixedly connected, therefore inductility.Because filter has entrance pipe in the actual connection of equipment
Mouth and the outflow mouth of pipe, because the entrance mouth of pipe of filter and the outflow mouth of pipe are not to install simultaneously, the installation after typically first,
For example first install the position of so filter after entering the mouth of pipe to determine that, however pipeline to be all that rigid member does not have flexible
Property, it is difficult to ensure that the pipeline being connected with the outflow mouth of pipe is just connected with the flange flowing out the mouth of pipe.Generally it is connected with the outflow mouth of pipe
Pipeline long, at the scene cutting with flow out the pipeline that is connected of the mouth of pipe, then by the flange of the outflow mouth of pipe, will be flowed by bolt
The flange of the flange of outlet spout and the pipeline corresponding with flowing out the mouth of pipe connects makes the outflow mouth of pipe of filter be connected with pipeline.Separately
Outward, on-site cutting pipeline need individually to carry cutting tool very inconvenient.
Unresolved the problems referred to above are it is thus proposed that installation telescopic flange needs to cut asking of pipeline to avoid the occurrence of
Topic.A kind of China as entitled " telescopic joint connects the equal pressure water pipe of machine cap " of Patent No. " CN204986128U " is practical
New patent, the flange being connected with top cover elbow including top cover elbow, water pipe, flange is creeping flange, and it includes flange A, method
Blue B, the first telescoping tube, the second telescoping tube, connecting tube, first telescoping tube one end and flange A fix, and the other end is passed through with connecting tube
Threaded, second telescoping tube one end and flange B fix, and the other end is threaded connection with connecting tube, and the inner surface of flange B is opened
It is provided with cannelure, cannelure built-in ring, flange B and water pipe are sealed by sealing ring, wherein sealing ring seals for blossom type
Circle.This patent realizes the length change in axial direction by two telescoping tubes, all extremely convenient during installation and removal, can be quick
Change the length of total.But this structure member is excessive, and structure is complex, is difficult to when actually used, and cost is relatively
Height is it is difficult to promote the use of on a large scale, and this structure can only be stretched on conduit axis, and when being impacted, pipeline is radially
Direction is difficult to the power of withstanding shocks, and easily damages.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As Fig. 1～2, a kind of extension flange structure, including valve pipe 1, the present embodiment and valve pipe 1 can also
It is the pipeline of other structures.Flange 2 and soft seal circle 3 are socketed on valve pipe 1, flange 2 offers valve pipe 1 and passes through
Through hole, the bottom (bottom of the present embodiment refers to the right direction of Fig. 1, and top refers to the left direction of Fig. 1) of through hole is to its bottom
Internal diameter is gradually increased the horn-like structure of formation, and flange 2, soft seal circle 3 and valve pipe 1 three be coaxially arranged, flange 2 and soft close
Seal 3 can move left and right, and is easy to the installation and removal of flange 2.
3 quality of rubber materials of the soft seal circle of the present embodiment are made, and can buffer rushing of the various directions that flange 2 is subject to
Hit, it is to avoid the direct impact between flange 2 and valve pipe 1.It is provided with a circle radially in the periphery of flange 2 bottom
The ring flange 4 of direction outwardly convex, ring flange 4 offers screw, and soft seal circle 3 is located between valve pipe 1 and flange 2,
Three is coaxially arranged and tight seal connects, and soft seal circle 3 bottom side protrudes from the end face of flange 2 bottom side.
The periphery of soft seal circle 3 is provided with the boss 5 of a circle radially outwardly convex, in the circumference of through hole bottom
The draw-in groove 6 of fixing lug boss 5 is offered on side end face, boss 5 is fastened in draw-in groove 6 and is fixedly connected with flange 2.Boss 5 bottom one
The end face of side and the bottom end face of soft seal circle 3, the part boss 5 positioned at its top side is fastened in draw-in groove 6, is located at
The sidepiece of the part boss 5 of its top side protrudes from the end face of flange 2 bottom side.Such setting structure is avoided that flange
Direct impact between more than 2 other attachment structures, a middle part across soft seal circle 3 convex platform 5, buffer most axle
To impulsive force.
The raised circle First terrace 7 of its axis oriented, the top of soft seal circle 3 are arranged on through hole inside circumference end face
Side is provided with second step face 8 corresponding with First terrace 7, and First terrace 7 is fitted tightly with second step face 8.The
One step surface 7 and second step face 8 one are so that flange 2 and the connection of soft seal circle 3 is more fitted, be in addition exactly prevent soft
Sealing ring 3 excessive to flange 2 top one side shifting.
As shown in Fig. 1～2, the periphery of valve pipe 1 offers a circle fixing groove 9, and engaging in fixing groove 9 has a circle
It is coaxial therewith the retainer plate 10 arranged, retainer plate 10 protrudes from the periphery face of valve pipe 1, and retainer plate 10 is merely able to solid
Determine to roll or immovable in groove 9.The inside circumference on flange 2 top be provided with a circle radially direction inwardly protruded with
The corresponding limit ribs 11 of retainer plate 10, retainer plate 10 is located between limit ribs 11 and the top of soft seal circle 3.Retainer plate 10
Limit flange 2, the excessive movement of soft seal circle 3, it is to avoid the phenomenon of parts loss occurs during dismantling flange 2 again.
But, because soft seal circle 3 needs certain axial feeding in practical application with during installing, and this
The amount of feeding beyond the deformation size of soft seal circle 3, so the present embodiment leave between soft seal circle 3 and retainer plate 10 soft close
