Description

Combined flange

Technical Field

The utility model relates to a flange production technical field especially relates to a modular flange.

Background

Flanges, also called flange plates or flanges, are parts of mutual connection between shafts, are used for connection between pipe ends, are also used for flanges on the inlet and outlet of equipment, are used for connection between two pieces of equipment, such as speed reducer flanges, flange connection or flange joints, are detachable connections which are formed by connecting flanges, gaskets and bolts with each other to form a combined sealing structure, are used for pipeline flanges, are used for pipeline equipment and are used for equipment inlet and outlet flanges, and are provided with holes, the two flanges are tightly connected through the bolts, and the flanges are sealed through gaskets.

The flange is generally through bolted connection, if the pipeline need bear torsion, then torsion can act on connecting bolt, if long-time use and the moment of torsion is great, then lead to connecting bolt fracture easily, current flange passes through the sealed of individual layer sealing washer simultaneously, and sealed effect is not ideal.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the flange in the prior art can not bear large torque through the bolt connection, and the shortcoming of the single-layer sealing ring that the sealing effect is unsatisfactory, and the provided combined flange.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a combined flange, includes first flange and second flange, first flange one side is provided with the ring gear, second flange one side card is equipped with first sealing ring, and the inboard welding of second flange has the second screw rod, and first flange one side card is equipped with the second sealing ring, and the welding of the first flange outside has first screw rod, and the outer surface welding of second flange has the connecting seat, connecting seat skin weld has the connecting rod, connecting rod skin is equipped with the clamp plate.

Preferably, one end of the second screw rod penetrates and extends to the outside of one side of the first flange, and a nut is connected to the surface of the second screw rod.

Preferably, the root of the second screw is sleeved with a sealing ring.

Preferably, one side of the second flange is provided with a tooth groove matched with the toothed ring.

Preferably, the surface of the pressure plate is provided with a jack matched with the connecting rod, the first screw rod and the second screw rod.

The beneficial effects of the utility model are that:

the flange is meshed with the tooth groove through the toothed ring, so that the anti-torsion effect is achieved, larger torsion can be borne, the sealing ring at the joint of the flange is extruded, and the sealing performance is improved.

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.

Referring to fig. 1-3, a combined flange comprises a first flange 1 and a second flange 2, wherein a toothed ring 3 is arranged on one side of the first flange 1, a first sealing ring 4 is clamped on one side of the second flange 2, a second screw rod 10 is welded on the inner side of the second flange 2, a second sealing ring 5 is clamped on one side of the first flange 1, a first screw rod 9 is welded on the outer side of the first flange 1, a connecting seat 6 is welded on the outer surface of the second flange 2, a connecting rod 7 is welded on the surface of the connecting seat 6, and a pressing plate 8 is sleeved on the surface of the connecting rod 7.

One end of a second screw rod 10 penetrates through and extends to the outside of one side of the first flange 1, a nut is connected to the surface of the second screw rod, a sealing ring is sleeved at the root of the second screw rod 10, a tooth groove matched with the tooth ring 3 is formed in one side of the second flange 2, and a jack matched with the connecting rod 7, the first screw rod 9 and the second screw rod 10 is formed in the surface of the pressing plate 8.

In this embodiment, after the second screw 10 welded to the second flange 2 side passes through the mounting hole in the surface of the first flange 1, the toothed ring 3 inside the first flange 1 is engaged with the toothed groove in the second flange 2 side, and since the second screw 10 is in clearance fit with the mounting hole of the first flange 1, the second screw 10 does not affect the engagement between the toothed ring 3 and the toothed groove.

Further, the clamp plate 8 is sleeved on the connecting rod 7, the jack on the surface of the clamp plate 8 is respectively sleeved on the surfaces of the first screw rod 9 and the second screw rod 10, the nuts are screwed on the surfaces of the first screw rod 9, the second screw rod 10 and the connecting rod 7, when the connecting rod 7 is screwed with the nut on the surface of the first screw rod 9, the first sealing ring 4 is extruded, the outer ring of the flange joint is sealed, the sealing ring at the root of the second screw rod 10 and the second sealing ring 5 are extruded by screwing the nut on the surface of the second screw rod 10, the internal sealing performance is guaranteed, meanwhile, the root of the second screw rod 10 is prevented from being leaked, and a better sealing effect is achieved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
