Abstract

The utility model discloses a spiral tube connecting piece, belonging to the paving technical field of water supply and drainage pipes; the spiral tube connecting piece comprises a pair of semi-circular pipe clamps (1) which are spiral waveforms matched with a spiral tube (4), the two radial sides of each pipe clamp are both provided with external-flanging edges (11), an elastic sealing ring (2) is arranged between the inner side of the pipe clamp and the outer wall of the connecting position of the two pipe ends, a section of universal glue is coated on the outer wall of the pipe, corresponding to the sealing ring, along the positions of spiral wave crest and wave trough, the external-flanging edge (11) opposite to the two pipe clamps (1) is provided with a fastening device. After adopting the structure, the structure of the connecting piece is simple, the operation is convenient, the connection can be carried out by general construction teams, thereby enhancing the connection sealing performance between the two pipes and greatly reducing the cost.

Description

The volute link

Technical field

The utility model belongs to the technical field that supplying drainage is laid, and specifically is a kind of volute link.

Background technique

Plastic spiral coil is 1920's, use the heavy caliber conveyance conduit of purposes such as burying ground draining, blowdown, irrigation as main industrial or agricultural and municipal administration from the alternative reinforced concrete pipe of external introduction, after this, the steel band of China's independent intellectual property right strengthens the PE helical bellows and also comes out one after another, because steel band strengthens the ring stiffness height of PE helical bellows, anti-pressure ability is good, and is corrosion-resistant, since coming out, be used widely, good development prospect is arranged.

The connecting means that steel band strengthens the PE helical bellows is normally in an end and the other end joint of pipeline, corresponding site in the pipeline inside and outside adds thermal weld with plastic welding gun and plastic welding rod earlier, wrap up welding with electro-fusion welding machine and electric smelting band in the appearance of jointing again, to play the interconnect function of sealing (closing water) and two pipes.Because the fusion techniques of these two kinds of methods, the construction team of common engineering contractor is difficult for grasping, there is not this equipment yet, to send the professional workforce to be with special device to weld and welding by the producer that produces pipeline to the job site, not only time-consuming but also require great effort, producer's after cost of producing pipeline is increased, in addition, meet under ponding or the rainy situation when the job site, must ponding be drained with suction engine, or with the water drainage, otherwise can not construct, because the charged submersible of workmen exists dangerous greatly, potential safety hazard is difficult to get rid of, and operation is in the open air met and is difficult to construction under the power free situation especially.

The model utility content

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of not only good seal performance, cost low, and simple in structure, easy to operate volute link.

To achieve these goals, a kind of volute link of the utility model comprises a pair of semiorbicular pipe clamp, described semi-circular pipe clamp is the spiral waveform that is complementary with volute, the radially both sides of described each pipe clamp are equipped with an outer rotating edge, be provided with elastic sealing ring between the outer wall of pipe clamp inboard and two pipe end joints, and at the pipe outer wall of seal ring correspondence, be coated with the preceding paragraph contact glue along spirality crest and trough place, two relative outer rotating edges of pipe clamp are provided with securing means.

The utility model also has following attached technical characteristics:

Described securing means is included on the relative outer rotating edge of two pipe clamps correspondence and offers a plurality of bolts hole, penetrates bolt in bolt hole, and the nut of screwing on bolt.

The length of described contact glue is 20cm.

Relative prior art, the beneficial effects of the utility model are: described semi-circular pipe clamp is the spiral waveform that is complementary with volute, the radially both sides of described each pipe clamp are equipped with an outer rotating edge, be provided with elastic sealing ring between the outer wall of pipe clamp inboard and two pipe end joints, and at the pipe outer wall of seal ring correspondence, be coated with the preceding paragraph contact glue along spirality crest and trough place, two relative outer rotating edges of pipe clamp are provided with securing means.After adopting this structure, make it simple in structure, easy to operate, general construction team just can finish it and connect, and the connection sealability, the cost that have strengthened between two pipelines significantly reduce.

Embodiment

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments:

Extremely shown in Figure 5 as Fig. 1, a kind of preferred embodiment that provides for a kind of volute link of the utility model, it is by a pair of spiral waveform return bend consistent with volute 4 waveforms folder 1 that made by plastics or glass fiber reinforced plastic, respectively there is outer rotating edge 11 the radially both sides of pipe clamp, edge's correspondence has a plurality of bolts hole 31 of two pipe clamps up and down that are used to tighten up, pipe clamp 1 inboard outer wall with two pipe end joints is placed elastomeric plastics or rubber disjunctor seal ring 2, and at the pipe outer wall of seal ring correspondence, coat the contact glue (adhesive) of the about 20CM scope of a segment length along spirality crest and trough place, on the bolt hole 31 at two outer rotating edge places radially, place stainless bolt 32, packing ring 34 is tightened up with nut 33, utilize the spirality crest of two pipe clamp 1 inboards and crest and the trough that trough presses the volute outer wall, water in preventing to manage outbound flows from the spiral chute and the tube wall top of joint, between in the two tube and tube folder, seal closely, body and pipe clamp firmly are connected are difficult for displacement, reach desirable Watertightness energy, this pipe clamp can be anticorrosion, therefore, described pipe clamp 1 is simple in structure, common builder is the energy complete operation just, greatly reduce producer's after service cost of producing pipeline, this pipe clamp 1 is applicable to that steel band strengthens PE helical bellows and other spirality plastic film capicitors.
