Abstract

The utility model discloses a dual-sheet pipe clamp connector which is used for connecting pipelines. The dual-sheet pipe clamp connector is matched with connecting bolts. The dual-sheet pipe clamp connector is characterized by comprising a sealing pad, a single-sheet pipe clamp and a pipe clamp copper ring, wherein the sealing pad is arranged in the single-sheet pipe clamp; and bolt holes are arranged on the single-sheet pipe clamp. In the utility model, the split single-sheet pipe clamp has simple exterior structure, and the PVC (polyvinyl chloride) pipelines and PE (poly ethylene) pipelines have the performances of high-efficiency, anti-dropping characteristic, good sealing performance and the like during the butt-jointed installing process; and simultaneously the dual-sheet pipe clamp connector also has the advantages of being manufactured conveniently and quickly.

Description

Two-piece pipe clamp joiner

Technical field

The utility model relates to a kind of pipeline connecting device, particularly a kind of coupling arrangement that is used for PVC, PE pipe joint.

Background technique

In PVC, PE piping erection, normally utilize two ends to have the joint of bellmouth type shape and the PVC of identical caliber, PE pipeline are inserted connect; Or utilizing an end to have flange, the connection set that an end has bellmouth docks PVC, PE pipeline.Utilize the joint of bellmouth type shape to carry out pipeline mating operation principle to be: rubber seal is installed in bellmouth, resiliently deformable by rubber seal after pipeline inserts realizes seal for pipe joints, frictional resistance stops PVC, the displacement of PE pipeline axial between external diameter by pipeline and rubber inside diameter simultaneously, plays purpose locking, anticreep; Utilizing an end to have connection set that flange and an end have bellmouth carries out the mating operation principle with PVC, PE pipeline and be: an end has the coupling arrangement of flange and utilizes bolt to connect with flange on PVC, the PE pipeline, and the other end then is connected with PVC, PE pipeline by rubber seal in the bellmouth.Above-mentioned pipeline is in connection process, though have characteristics simple and quick, easy to use, under, the situations such as the insertion amount is few, paved surface out-of-flatness big at outer diameter tube size scattered error, the sealability of pipeline is difficult to guarantee, and easily causes axially and come off.Therefore, the novel coupling arrangement device of a kind of efficient, anticreep of design, good seal performance is with significant.

The model utility content

To achieve these goals, the utility model provides a kind of two-piece pipe clamp joiner, is used for pipeline and connects, is furnished with attachment bolt, it is characterized in that: comprise sealing gasket, monolithic pipe clamp, pipe clamp copper ring, sealing gasket is put in the monolithic pipe clamp, on the monolithic pipe clamp bolt hole is arranged.

Further technological scheme also comprises:

Described monolithic pipe clamp is provided with pipe clamp copper ring skew notch, and described pipe clamp copper ring is positioned in the copper ring skew notch.

Described pipe clamp copper ring internal surface is a triangle helical teeth shape.

Described pipe clamp copper ring angle and the axial oblique angle of pipe clamp copper ring skew notch are 30 degree.

Described sealing gasket is laminar rubber, is evenly distributed with square hole groove, groove muscle on the sealing gasket, and the sealing gasket docking port is thick gluey projection.

As preferably, described square hole groove is of a size of 6mm * 6mm, the wide 2mm of groove muscle muscle, the thick 7mm of sealing gasket butt joint chewing-gum.

As preferably, described monolithic pipe clamp is two, and two pipe clamp docking port gaps are 4-5mm.

The employed split type monolithic pipe clamp appearance structure of the utility model is simple, makes PVC, PE pipeline have performances such as efficient, anticreep, good seal performance in butt joint is installed, and has easily manufactured advantage such as quick simultaneously concurrently.

Embodiment

Contrast accompanying drawing below,, embodiment of the present utility model is described in further detail by description to embodiment.

Fig. 1 is the utility model structural representation, and it is by 1,4 bolt hole 2 of two EPDM sealing gaskets, a pair of real

monolithic pipe clamp

3, and 4,4 attachment bolts of a pair of pipe clamp copper ring 5 are formed.

EPDM sealing gasket 1 is laminar rubber as shown in Figure 4, on equally distributed square hole groove 8 is arranged, square hole groove width 6mm * 6mm; Sealing gasket docking port 10 is thick gluey projection, has enough sealing resiliently deformables, thick 7 mm of interface 10 glue when two sealing gaskets dock for satisfying; The even groove muscle 9 of sealing gasket distributes the wide 2mm of muscle for the muscle shape; Two EPDM sealing gaskets 1 are put in the monolithic pipe clamp 3, after PVC, PE pipeline insert two-piece pipe clamp joiner, pass through bolton, make two monolithic pipe clamp radial contraction, sealing gasket docking port 10, the even groove muscle 9 of sealing gasket hug outer diameter tube, thereby play the sealed against leakage effect on the use EPDM sealing gasket 1.

Have 4 bolts hole 2 on the monolithic pipe clamp 3 as shown in Figure 1, attachment bolt 5 docks two monolithic pipe clamps 3 by above-mentioned bolt hole 2.

Pipe clamp copper ring skew notch 6 is arranged on the monolithic pipe clamp 3 as shown in Figure 2, axially oblique angle 30 is spent, two pipe clamp copper rings 4 as shown in Figure 5 are positioned in the copper ring skew notch 6, after attachment bolt 5 compresses 3 connections of two monolithic pipe clamps, drive 4 radial displacements of pipe clamp copper ring, play that institute's intubate part is clamped the anticreep effect outward.

Two pipe clamp docking port 6 gaps as shown in Figure 3 are 4-5 mm, to guarantee having enough radial displacement spaces after two pipe clamps 3 compress by bolt.

Two pipe clamp copper rings 4 as shown in Figure 5, its pipe clamp copper ring angle 7 axial oblique angles 30 degree, for guaranteeing that pipe fitting axially tightens anticreep, its pipe clamp copper ring 4 internal surfaces are designed to triangle helical teeth shape, and as shown in Figure 5, this structural design can play good chucking anticreep effect.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
