Abstract
The utility model discloses a thin-wall metal pipe eversion flat-edge connecting piece, which comprises a pipe body, a pipe joint, pairwise cooperated flanges, and bolts used for connecting and fastening the flanges. The end mouths of the pipe body and the pipe joint are all turned out to have parallel outer flanges, the pairwise cooperated flanges are respectively sleeved at the backs of the parallel outer flanges of the pipe body and the pipe joint, a sealing washer is arranged between the parallel outer flanges of the pipe body and the pipe joint, the bolts fasten the flanges, the parallel outer flanges of the pipe body and the pipe joint inwardly fasten the sealing washer to form seal connection. The design of the utility model provides a connection way which is different from a convex ring pipe, and has the advantages that the connection strength of the pipe end is good, the assembly and the disassembly are convenient, and the tightness is good, etc., in particular, the gap at the connection position of the pipe pieces is small, and the remainder is not easy to be gathered. The utility model is particularly suitable for the delivery connection of the medical treatment and the food production, etc. which have high requirements on the hygiene conditions.
Description
Technical field
The utility model relates to the pipe fitting that is tightly connected in the field, particularly thin metallic tubd of liquid, gas delivery connection pipe fitting.
Background technique
The port of traditional thick-wall metal pipes hinge thread ways of connecting owing to will damage body and reserve the machining allowance of hinge thread, causes that the metallic material waste is serious, cost of production is high, is substituted by thin metallic tubd and connection pipe fitting gradually.As present more popular thin-wall metal bulge loop Placement, adopt pipe end diffusion moulding bulge loop, neither damage body, can save metallic material in a large number again, in the extensive use of normal domestic field.But because there is the seam of certain-length in the bulge loop tube and tube spare place of being tightly connected, gather residue easily, therefore still can't use in the field of hygienic requirements strictnesses such as medical treatment, food production.
The model utility content
The purpose of this utility model is to overcome the deficiency that conventional art is tightly connected, and it is little to propose a kind of sealing transition seam, good seal performance, the outer down tilt limit of the thin metallic tubd of firm and reliable connection connection pipe fitting.
The purpose of this utility model is achieved by the following technical solution: the outer down tilt limit of thin metallic tubd connection pipe fitting, include body, pipe joint, the flange plate that cooperates in pairs, connect the bolt that the clamp flange dish is used, the port of body and pipe joint all turns up flat mouthful outer rim, the corresponding flange plate that fastens of negative and positive is placed in flat mouthful of outer rim behind of body and pipe joint respectively, be provided with seal washer between the flat mouthful of outer rim of body and pipe joint, bolt tightens up flange plate, and flat mouthful of outer rim of body and pipe joint clamps seal washer formation in opposite directions and be tightly connected.Further, be convenient butt joint, location, be placed in flange plate on body and the pipe joint and be respectively the male flange and the concave station flange that can corresponding negative and positive fasten.And flange plate is placed on the pipe joint movably, but also solid welding is due to the flat mouthful outer rim of pipe joint behind.For adapting to the quick mounting or dismounting of pipe fitting, flange plate adopts the lap joint flange of two semicircular ring of detachable one-tenth.For realizing hard sealing or the soft seal under the different condition, seal washer can adopt soft metal packing ring or rubber washer or both combinations.
Such linkage structure has tangible advantage:
1, body need not carry out damaging processing, carry out the port flange before need only connecting and become a flat mouthful outer rim to get final product;
2, the gap, joint of body and pipe joint is little, is difficult for accumulating residue, meets to carry the hygienic requirements that connects in medical treatment, the food production;
3, the flange assembly is convenient, flexible, quick;
4, be connected firmly, good airproof performance.
When 5, being tightly connected firmly, pipe fitting can bear 250 ℃ of limiting temperatures that connect far above soft seal, can use under the environment more than 300 ℃.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic representation of lap joint flange.
Embodiment
Connection pipe fitting referring to Fig. 1, present embodiment mainly is made of pipe joint 1, body 2, concave station flange 3, male flange 4 and the soft metal seal washer 5, the bolt 6 that all are stainless steel, pipe joint 1 is 90 ° a bend pipe, its port forms flat mouthful outer rim 11 through flange, the shoulder hole 31 corresponding with flat mouthful of outer rim 11 arranged on the concave station flange 3, and concave station flange 3 is placed in the behind of 1 flat mouthful of outer rim of pipe joint 11; The port of body 2 also forms flat mouthful outer rim 21 through flange, and 4 of male flanges are placed in the behind of 2 flat mouthfuls of outer rims of body 21.Male flange 4 and concave station flange 3 mutually just in time yin yang complementarity fasten, be provided with between them and intert the screw 8 of bolt 6 lockings mutually.
When body 2 is connected assembly with pipe joint 1, flat mouthful of outer rim 11 retaining rings of pipe joint 1 are in the shoulder hole 31 of concave station flange 3, put into the internal diameter soft metal seal washer 5 consistent earlier with pipe joint 1 internal diameter, make seal washer 5 be affixed on flat mouthful of outer rim 11 surfaces, male flange 4 inserts in the shoulder hole 31 of concave station flange 3 together with flat mouthful of outer rim 21 covers of body 2, make each screw alignment, inserting bolt 6 screws then.At this moment, flat mouthful of outer rim 21 of male flange 4 pushing bodys 2 compresses seal washer 5, the shoulder hole 31 of concave station flange 3 also pushes flat mouthful of outer rim 11 of pipe joint 1 simultaneously, also oppositely compress gasket circle 5, thereby two flat mouthfuls of outer rims 11,21 clamp seal washer 5 in opposite directions, form firm being tightly connected.
Certainly, seal washer 5 is realized being tightly connected firmly between the pipe fitting except adopting the soft metal packing ring; Also can adopt rubber, plastic seal ring, realize that the soft seal between the pipe fitting connects; Also can be used in combination metal simultaneously is connected with nonmetal two kinds of washer sealings.
In addition to the implementation, as shown in Figure 2, the flange plate that is fastenedly connected can adopt lap joint flange 7, be that each flange is made of two detachable semicircular ring, have the screw of interspersed bolt 6 on the semicircular ring, like this, lap joint flange 7 can overlap at any time and be buckled on body or the pipe joint, also can pull down convenient on-the-spot construction at any time.In addition, pipe joint is except that above-mentioned 90 ° of bend pipes, and pipe fittings such as also available common straight-through tube, three-way pipe, four-way pipe, bend reducer are replaced, as long as the outer down tilt limit of tube opening.
Certainly, only enumerated two kinds of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
