Abstract
The invention discloses a variable span flange interface type dummy valve connector. The variable span flange interface type dummy valve connector comprises two flanges which are arranged oppositely and a threaded adjuster which is mounted between the two flanges and connects the two flanges into a whole body, wherein each flange is provided with multiple adjusting holes, and bolts and nut pairs are mounted in the adjusting holes; the threaded adjuster is provided with two sliding rod threaded shafts which are connected with the two flanges respectively and a threaded adjusting shaft which connects the two sliding rd threaded shafts into a whole body, the threaded adjusting shaft is provided with a hole, and an adjusting handle is mounted in the hole in a matched mode. The variable span flange interface type dummy valve connector is easy to operate, accurate adjustment can be conducted on dummy valves with different spans, and the adjustment problem of the dummy valves with different spans is solved; in addition, the variable span flange interface type dummy valve connector can be recycled, construction cost is greatly saved, and work efficiency is improved.
Description
Technical field
The present invention relates to connector, relate in particular to a kind of in pipeline installation process, can be to differenceThe false valve connector of the interim variable span flange-interface formula connecting of flange of span, different pressures grade. Belong toYu Haiyang petroleum works field.
Background technology
At present, in petroleum industry pipeline installation process, because the valve that various delivery cycles are grown can notArrival is installed on time, therefore, in order to ensure construction speed, in some pipeline construction processes, need to do oneThe false valve of series is installed temporarily, to avoid occurring treating work situation. Conventionally, do for interim installation of false valveMethod is directly to adopt two to open circular hole disk, middle by a connecting rod be welded into one non-dismountable,Can only replace a kind of false valve of specification valve. Because this kind of connected mode is fixed, can not adjustJoint, when false valve demand is large, specification is many time, this kind of mode need to be according to false valve specification, does a lotPlant false valve, so, can cause very large waste to construction.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provides a kind of variableThe false valve connector of span flange interface type, it is simple to operate, not only can carry out the false valve of different spansFine adjustment, has solved the adjusting problem to the false valve of different spans; And, can reuse, greatly jointApproximately construction cost, improved operating efficiency.
The object of the invention is to be realized by following technical scheme:
The false valve connector of a kind of variable span flange-interface formula, is characterized in that: comprising: be oppositely arrangedTwo flanges, be arranged on the thread regulator connecting as one between two flanges and by two flanges, itsIn, flange is provided with bolt, nut pair is installed in several adjustment holes, adjustment hole; This thread regulatorBe provided with: the two slide bar thread spindles that are connected with two flanges respectively, the spiral shell that two slide bar thread spindles are connected as oneLine regulating shaft, this threaded adjusting axle is provided with a hole, in hole, coordinates a regulating handle is installed.
On the bolt of described bolt, nut centering, be set with sleeve and packing ring.
On the bolt of described bolt, nut centering, be also set with the gap piece of a setting thickness.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it is simple to operate, not onlyCan carry out fine adjustment to the false valve of different spans, solve the adjusting problem to the false valve of different spans;And, can reuse, greatly save construction cost, improve operating efficiency.

Detailed description of the invention
As Figure 1-Figure 5, the present invention includes: two flanges 4 being oppositely arranged, be arranged on two flangesThe thread regulator 6 connecting as one between 4 and by two flanges 4, wherein, flange 4 is provided with several tuneBolt, nut are installed to 3 in knothole, adjustment hole; This thread regulator 6 is provided with: respectively with two flanges 4The two slide bar thread spindles (5,7) that connect, adopt thread connecting mode by two slide bar thread spindles (5,7)The threaded adjusting axle connecting as one, this threaded adjusting axle is provided with a hole, in hole, coordinates a tune is installedJoint handle.
In order to ensure the accuracy of alignment of left and right two flanges 4, above-mentioned bolt, nut are to being set with on the bolt in 3There are sleeve 2 and packing ring.
If the fluting thread spindle 5 of selecting and slide bar thread spindle 7 length are inadequate, above-mentioned bolt, nut are in 3On bolt, can also be set with the gap piece 8 of a setting thickness, thereby, increase span, widen span scope.
When use, by the end of the slide bar thread spindle 7 in the slotted hole at insertion flange 4 centers, and pass throughTo 3 lockings, can there is not circumferential rotation in bolt, nut; Then, by left and right slide bar thread spindle 7 by twoFlange 4 connects together; Rotation regulating handle, adjusts to predetermined value two flange 4 spans; Then,By bolt, nut to 3 and packing ring finally two of left and right pipeline is coupled together. When changing different lengthThread regulator 6, the gap piece 8 of different-thickness, when the flange 4 of different size, just can be combined into arbitrarilyThe false valve connector of specification, to be applicable to the interim cross-over connection of the false valve flange 4 of more specifications.
The above, be only preferred embodiment of the present invention, not the present invention done any formalRestriction, any simple modification that every foundation technical spirit of the present invention is done above embodiment, etc.With changing and modifying, all still belong in the scope of technical solution of the present invention.
