In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an exempt from to weld flange for pipeline, is including the outer lane, and the seal gasket I of installing between two flanges is installed to the inner circle, the lower surface of outer lane is opened there is the groove of agreeing with, and inside is opened there is the thread groove, and when two agree with the groove alignment, the thread groove on the outer lane also can be aimed at, inserts earlier agreeing with the piece agree with the groove, and the thread groove aligns more easy to assemble screw rod two this moment, evenly open in the middle of the inner circle has four thread grooves, just screw rod one is worn to be equipped with by the inside level of inner circle, seal gasket two is installed to the lower part of the inner wall of inner circle, the latter.
As a further description of the above technical solution:
and when the fit grooves of the two flanges are aligned, the two flanges can be fixed by fit blocks.
As a further description of the above technical solution:
and the inner ring is provided with four thread grooves which are in threaded connection with the first screw rod.
As a further description of the above technical solution:
and the front end of the first screw rod is provided with an anti-skid gasket.
As a further description of the above technical solution:
the shape of antiskid gasket is circular-arc, conveniently laminates the steel pipe.
As a further description of the above technical solution:
the first sealing gasket is also provided with an opening for penetrating the wedge block and the second screw rod.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. use earlier before two flanges of erection joint to agree with the piece and fix two flanges, make two flanges fixed together, play the effect of location, twist more convenience of screw rod this moment again, difficult emergence skew.
2. Four screw rods with arc-shaped anti-skidding gaskets are adopted to fix the steel pipe instead of welding, and if the steel pipe breaks or the flange leaks, the whole part does not need to be replaced, so that the part with problems can be disassembled and replaced.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an exempt from to weld flange for pipeline, is concrete, as shown in figure 1, including outer lane 1, inner circle 2, install seal gasket 6 between two flanges, the lower surface of outer lane is opened and is agreed with groove 7, and inside is opened there is the thread groove, and when two agree with the groove 7 alignment, the thread groove on the outer lane also can aim at, inserts with a letter 10 earlier agree with the groove, the thread groove aligns more easy to assemble screw rod two 4 this moment, evenly opens in the middle of the inner circle has four thread grooves, just screw rod one 3 is worn to be equipped with by 2 inside levels of inner circle, and seal gasket two 8 are installed to the lower part of the inner wall of inner circle, and the latter half of inner circle leans out, the fixed.
Specifically, as shown in fig. 1, the two flanges may be engaged and fixed by the engagement blocks 10 when the engagement grooves 7 are aligned, so as to limit the rotation between the two flanges.
Specifically, as shown in fig. 1, four thread grooves are formed on the inner ring 2, and the inner ring and the first screw rod 3 can be in threaded connection and are used for fixing the steel pipe.
Specifically, as shown in fig. 2, an anti-slip gasket 9 is installed at the front end of the first screw rod 3 to prevent the steel pipe from slipping.
Specifically, as shown in fig. 2, the anti-slip pad 9 is arc-shaped, and is convenient for adhering to a steel pipe.
