Abstract
The utility model relates to a loose flange typed conduit joint, comprising a pipe connection body (1) arranged with a flange (5), a movable flange (2), a jump ring (3), a sealing ring (4) and a pipe (8). A ring groove (9) is opened on the pipe (8), the jump ring (3) belonging to an open ring is inlaid into the ring groove (9) opened on the pipe (8). The pipe (8) arrangedon one side of the jump ring (3) is sequentially sleeved with the sealing ring (4) and the pipe connection body (1) arranged with a flange (5), and the other side of the pipe (8) is coated with the movable flange (2). The flange plate of the movable flange (2) is arranged with the drum connection (7) of which the bore diameter of the tail-end contracts. The flange plate of the pipe connection body (1) arranged with the flange (5) is provided with a projecting spigot (6) over the plate surface, the outer diameter of the spigot (6) is slightly less than the inner diameter of the movable flange (2), and the pipe connection body (1) can employ direct connection, triplet, cross joint and angle fitting. The utility model overcomes the disadvantages of the existing technology, and the conduit joint can fix the flange plates to the tubes without employing the methods of welding or the like, thereby the utility model can be adaptable for the connection requirements of various materials. Besides, the piping connection of the conduit joint can be realized without special equipment or professional technologists, and then the on-site construction is time-saving, labor-saving, convenient and reliable.
Description
The utility model belongs to the pipe fittings field, specifically is the pipe coupling of a kind of loose flange formula.
By the connection of flange plate realization tube and tube, be a kind of reliable and basic pipe Connecting format.The pipe bigger for the bore of pipe connects, and the employing of this mode is more general.In the prior art, known flange-type pipeline connects, and requires flange plate is fixed on the termination of pipe, and its means of fixation is generally welding.This material to field condition and pipe all has specific requirement.The welding equipment of needs power supply easily, special use and well-trained professional construction personnel etc.The field welding difficulty of some tubing is higher, and as aluminum pipe, copper pipe and thin-wall stainless steel or the like, many difficulties of field welding cause operating expenses high.Some NEW TYPE OF COMPOSITE tubing are more arranged, mould metal tube as lining, itself also is not suitable for high-temperature soldering.In a word, traditional fixed flanged pipe is connected with significant limitation.
The purpose of this utility model is in order to overcome the defective of prior art, and for people provide the pipe coupling of a kind of loose flange formula, it need not by modes such as welding flange plate to be fixed on the pipe, thereby can be applicable to the needs that the pipe of various materials connects.Simultaneously, this pipe joint does not need Special Equipment and professional and technical personnel when realizing that pipe connects, and site operation is time saving and energy saving, and is convenient and reliable.
The purpose of this utility model realizes by following technical proposals:
Loose flange formula of the present utility model pipe coupling, union body (1) by flanged (5), loose flange (2), jump ring (3), seal ring (4), (8) five parts of pipe are formed, it is characterized in that having on the pipe (8) circular groove (9), jump ring (3) is embedded in the circular groove (9) of pipe (8) for trip ring, be with seal ring (4) successively on the pipe (8) of jump ring (3) one sides, the union body of flanged (5) (1), be with loose flange (2) on the pipe of opposite side (8), have a tubular interface (7) on the flange plate of loose flange (2), shrink in the afterbody aperture of interface; The seam (6) that an outstanding card is arranged on the flange plate of the union body of flanged (5) (1), seam outer through being slightly less than the internal diameter of loose flange (2).
In the such scheme, described union body (1) can be lead directly to, threeway, four-way and elbow etc.
In the such scheme, described jump ring (3) is made of metallic material, and seal ring (4) is made of rubber or other sealing material.
This reality has novel installation process to be achieved in that the first step, slot rolling on the appropriate location of distance pipe (8) termination; Second step, loose flange (2) is through on the pipe (8), jump ring (3) is contained in the circular groove of having held successfully on the pipe (8) (9), wherein the diameter of jump ring (3) is greater than groove depth, internal diameter is slightly less than the footpath, the end of groove, and seal ring (4) is enclosed within the cavity that loose flange (2) were gone up and filled in to pipe (8); The 3rd step, pipe (8) termination is injected in the union body (1) of flanged (5), simultaneously, the seam (6) on union body (1) flange plate also inserts the cavity of loose flange (2); In the 4th step, the flange (5) on loose flange (2) and the union body (1) is compressed with bolt (10), packing ring (11), nut (12).In the process that compresses, the seal ring (4) in the corresponding activity compression flange of flange seam (6) (2) interface on the union body (1) reaches sealing effect.Simultaneously, owing to be embedded in the jump ring (3) in the pipe circular groove (9), the internal diameter that its diameter closes up greater than loose flange (2) afterbody is so pipe (8) unlikely retreating under the state of loose flange (2) and union body (1) flange screw becomes reliably thereby make to connect with sealing.
Originally belonging to the novel designer of being sums up out by long-term practice, it has overcome the defective of prior art, for people provide the pipe coupling of a kind of loose flange formula, it need not by modes such as welding flange plate to be fixed on the pipe, thereby can be applicable to the needs of the pipe connection of various materials.Simultaneously, this pipe joint does not need Special Equipment and professional and technical personnel when realizing that pipe connects, and site operation is time saving and energy saving, and is convenient and reliable.
Further describe the utility model below by embodiment, the utility model is not limited only to described embodiment.
Accompanying drawing 1 is installation of the present utility model and overall structure schematic representation.
Accompanying drawing 2 is the structural representation of the union body in the accompanying drawing 1: wherein A is a stereogram; B is a sectional view; C is that the Y of B is to view.
