Connecting rod through through hole and the fixture corresponding on two pipe flanges is stated, wherein the fixture is located at institute
State the side of the close vessel flange in pipe flange.Pipe flange component of the present utility model is not only simple in structure, and uses
Space is small, and under the mating reaction of connecting rod and fixture, the pipe flange that can be pointed to intermediate equipment two ends is carried out
Support is fixed, and makes to produce certain interval between pipe flange and vessel flange, so as to by intermediate equipment from two neighboring connecting rod
Between fast assembling-disassembling.Tolled breakdown by the means such as prizing, push up, pound, draw in so avoiding being needed when being connected using conventional flange and
The damage caused to flange, and improve efficiency and security to intermediate equipment dismounting.
Preferably, the beeline between two neighboring fixture is S, and the outside dimension of the vessel flange is D, wherein
At least one S >=D.So when being supported to pipe flange by connecting rod and fixture, as long as pipe flange and equipment
The gap that appearance can be relatively moved between flange, reduces the requirement to gap size, improves to intermediate equipment dismounting
Efficiency.
Preferably, the excircle of the flange body is provided with two support ears.
Preferably, the excircle of the flange body is provided with three support ears.Further preferred three supports
Ear is arranged into equilateral triangle.By uniform three support ears on the excircle of flange body so as to improve fixture to pipeline
The stability of flange support.
Preferably, the connecting rod uses double threaded screw.It is further preferred that the fixture uses outer-hexagonal nut.
Brief description of the drawings
Fig. 1 is structural representation when the utility model pipe flange component is connected with intermediate equipment；
Fig. 2 is the structural representation of pipe flange in the utility model pipe flange component；
Fig. 3 be Fig. 1 in A-A to structural representation.
Specific embodiment
The technical solution of the utility model is introduced below in conjunction with the accompanying drawings.
Fig. 1 show structural representation when the utility model pipe flange component is connected with intermediate equipment.The tube method
Blue component includes pipe flange 1, connecting rod 2 and fixture 3.Wherein, pipe flange 1 with there is certain retractility or thin-walled
Pipeline 4 is fixedly connected, and circular vessel flange 5 is fixedly connected with intermediate equipment 6.In the utility model, intermediate equipment 6 is one
Section is used for the equipment that pipeline, or the pump housing, valve, blower fan and air-valve of transition etc. need dismounting maintenance.Now, tube method
Blue 1 is fixedly connected with vessel flange 5 by connecting bolt 7 and hex nut 8, and then completes the end pipe of intermediate equipment 6 and two
The connection on road 4.
With reference to shown in Fig. 2, pipe flange 1 includes flange body 11, support ear 13 and is distributed on the end face of flange body 11
On bolt hole 12, wherein bolt hole 12 be used for wear connecting bolt 7, realize the company between pipe flange 1 and vessel flange 5
Connect.Additionally, being provided with three support ears 13 on the excircle of flange body 11 in the utility model, set on each support ear 13
There is a through hole 14, and all through holes 14 are located at radian≤π of the identical graduation circle above and between two through holes 14 of arbitrary neighborhood.
Further preferably, three support ears, 13 one-tenth equilateral triangle arrangements, now the radian between two neighboring through hole 14 is 2/3 π, and
Nearest back gauge between two neighboring through hole 14 is L.
With reference to shown in Fig. 3, the outside dimension of the vessel flange 5 being connected with pipe flange 1 is D, then two neighboring through hole 14
Between nearest back gauge L >=D.When the connection for carrying out intermediate equipment 4 and pipeline 2 first is installed, intermediate equipment 4 is straight with pipeline 2
Connect piping ring flange 1 to be fixedly connected with intermediate equipment flange 3, connecting bolt 5 is each passed through the spiral shell on pipe flange 1
It is locked by hex nut 6 after bolt hole on keyhole 12 and intermediate equipment flange 3.
With reference to shown in Fig. 1, the intermediate equipment 6 for outside dimension less than the outside dimension D of vessel flange 5, using this practicality
The process that new pipe flange component is removed is as follows：
First, connecting rod 2 is each passed through corresponding through hole 14 on the pipe flange 1 at the two ends of intermediate equipment 6, and
And also cross positioned at the fixture 3 near the side of vessel flange 5 during through through hole 14.Wherein, it is new in this practicality
Fixture 3 selects outer-hexagonal nut in type, and connecting rod 2 so is fixed on into two pipes by two fixtures 3 in connecting rod 2
Between road flange 1.In the utility model, connecting rod 2 uses double threaded screw.
Then, by manual wrench by the connecting bolt 7 and hex nut 8 between connecting pipe flange 1 and vessel flange 5
Dismounting.Now, although removed connecting bolt 7 and hex nut 8, but due to two ends pipeline 4 to intermediate equipment 6 still
The seal for sealing is provided with certain thrust and between pipeline 4 and intermediate equipment 6, so being set in the middle of now
Standby 6 also directly cannot smoothly take out.
Finally, manually spanner carries out being alternately rotated operation to all of fixture 3, makes fixture 3 along connecting rod 2
Axis is moved to the direction of pipe flange 1.Because pipeline 4 has certain retractility, therefore pipe flange 1 is in the band of fixture 3
Moved to the direction of two side ducts 4 respectively under dynamic, make to produce gap between pipe flange 1 and vessel flange 5.Due to L >=D, institute
So that when the gap between pipe flange 1 and vessel flange 5 reaches certain size, such as gap size is more than the thickness of fixture 3
Degree, you can intermediate equipment 6 is smoothly removed between two adjacent connecting rods 2.
When being installed again to intermediate equipment 6, due to the effect of connecting rod 2 and fixture 3, make the tube method at two ends
There is certain distance between blue 1.Therefore, it can that quickly and easily intermediate equipment 6 is put between two ends pipeline 4, and by handing over
The reverse rotation fixture 3 for replacing makes the pipeline 4 at two ends slowly near intermediate equipment 6, and then makes pipe flange 1 and vessel flange 5
Between bolt hole accurate alignment.Then, pipe flange 1 is completed by connecting bolt 7 and hex nut 8 and vessel flange 5 is solid
Fixed connection.
Further preferably, with reference to shown in Fig. 3, when the position of through hole 14 is designed and from connecting rod 2 and fixture 3,
If the beeline between two neighboring fixture 3 is S, S >=D.As long as so between pipe flange 1 and vessel flange 5
During the gap that appearance can be relatively moved, you can smoothly remove intermediate equipment 6.And no longer need to the He of pipe flange 1
The gap size between the two of vessel flange 5 has further restriction, so as to further improve the disassembly efficiency to intermediate equipment 6.
Additionally, according to pipeline 4 and the size of intermediate equipment 6, varying number can be set in flange body 11
Support ear 13, such as set two support ears 13 or in the outer of flange body 11 in the same diametric(al) of flange body 11
Uniform four support ears 13 can realize the rapid and convenient dismounting to intermediate equipment 4 on circumference.
