Abstract

The utility model discloses a large-diameter hoop-type glass reinforced plastic tube connecting component for connecting glass reinforced plastic tubes. The glass reinforced plastic tubes comprise a first tube and a second tube. The connecting component is characterized by comprising sealing rings for connecting end holes of the two tubes, wherein ferrules for hooping the tubes are arranged on the left and right sides of the sealing rings; the sealing rings and the ferrules are locked and fixed through bolt pairs by a hoop. The connecting component can enhance the leakproofness of tube connection, can prevent the tubes from shedding off by external force, is convenient and rapid to mount and is applicable to connection of large-diameter pipelines and emergency repairing construction in the case of tube explosion and water leakage of pipelines.

Description

A kind of heavy caliber cuff formula frp pipe connection part

Technical field

The utility model belongs to fiberglass plastic clamp sand pipe associated conduit laying construction and fiberglass plastic clamp sand pipe tubing connection pipe fitting production is manufactured field, is a kind of heavy caliber cuff formula frp pipe connection pipe fitting.

Background technique

Domestic existing fiber reinforced plastic pipe connects sealed pipe fittings, is mostly to adopt bayonet joint pipe fitting, and this connection pipe fitting is only applicable to the tubing of caliber below 1 meter and connects.Existent defect when tubing at caliber more than 1 meter uses: 1., when tubing docks with pipe fitting installation, must be furnished with large-scale docking and advance adapter equipment just can complete, but be to realize in pipeline laying construction place.2. necessary disposable success while adapter, not in place, defective once socket joint connection, pipe fitting is difficult to deviate to reinstall from tubing again, haves much room for improvement.

Chinese patent is rear CN201210174780.2 openly, the name of innovation and creation is called " a kind of for the seal sleeve interface of connecting glass fiber reinforced plastic and for the fiber reinforced plastic pipe of this interface ", the deficiency of this patent is likely because the excessive sealing effect that causes of hydraulic pressure is not fine, and overall structure does not possess the function that prevents that pipeline from falling back.

Model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good sealing effect is provided, and anti-tubing is deviate from and connection part is easily installed.

In order to realize the object of this model utility, the technological scheme of employing is as follows:

A kind of heavy caliber cuff formula frp pipe connection part, for momentary connection glass-reinforced plastic material, described frp pipe comprises the first tubing and the second tubing, comprise the seal ring that connects two pipe ends, the described seal ring left and right sides is provided with the lasso for entangling tubing, and described seal ring and lasso are locked by bolt pair by cuff.

Particularly, adopt the utility model first to allow two pipe ends insert in seal ring, their close contacts are coordinated, then in the seal ring left and right sides that has connected tubing, lasso is set and entangles two tubing, prevent that them from falling back out, finally by cuff, the entirety coupling together is fixed to locking above.

Preferably, described seal ring shaft section is I shape.

The utility model can make the port of first, second tubing contact with it with intimate is convenient by the seal ring that uses I shape, reaches good sealing effect.

Preferably, described lasso comprises the first lasso and the second lasso, and the first lasso correspondence is entangled the first tubing, and the second lasso correspondence is entangled the second tubing.

Preferably, described first, second lasso be shaped as cylindrical shape or sheet type.

Preferably, first, second described lasso inwall is equipped with and sets one's teeth on edge.

It is in order to prevent falling back of tubing that the lasso inwall is here provided with the structure of setting one's teeth on edge.

Preferably, described cuff is provided with opening, and cuff opening both sides arrange hangers.

Preferably, described hangers evenly has two or more bolts hole.

The present invention is compared with the prior art, and the beneficial effect having is:

1. in the time that in pipe, water supply pressure increases, seal ring due to its I-shaped structure will be by inner tube wall subsides tightr;

When tubing produces external force tubing because of extraneous factor will be when releasing in pipe fitting, the setting one's teeth on edge to produce in distortion of lasso inwall turns over tubing bellmouth outer wall embraced tightlyer, therefore plays and prevents the object of tubing from deviating from pipe fitting;

3. manually easy for installation, quick;

4. due to the convenient and easy use operation of integrated connection mode of the present utility model, can be used for the connection of large diameter pipeline.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

Embodiment:

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the connection part of heavy caliber cuff formula frp pipe, for momentary connection glass-reinforced plastic material, described frp pipe comprises the first tubing 1-I and the second tubing 1-II, this connection part comprises the seal ring 2 that connects two pipe ends, described seal ring 2 left and right sides are provided with the lasso 3 for entangling tubing, and described seal ring 2 and lasso 3 are locked by bolt pair by cuff 4.

Described lasso 3 comprises the first lasso 3-I and the second lasso 3-II, and described the first lasso 3-I correspondence is entangled the first tubing 1-I, and the second lasso 3-II correspondence is entangled the second tubing 1-I.

Described seal ring 2, for adopting the rubber seal that shaft section is I shape, entangles the first tubing 1-I and the second tubing 1-II port, in the time that inside water pressure increases, can make the inwall of seal ring 2 more be close to tubing, increases sealing.Described lasso 3 is cylindrical shape, inwall is provided with sets one's teeth on edge 6, when entangling after pipe end, set one's teeth on edge and 6 be close to tubing docking joint socket outer wall, when tubing produces external force tubing because of extraneous factor will be when releasing in pipe fitting, set one's teeth on edge to produce in distortion and turns over tubing bellmouth outer wall is embraced tightlyer, therefore play and prevent the object of tubing from deviating from pipe fitting.

Cuff shown in Fig. 9 is selected stainless steel material, reaches the connection of tubing after lasso entangles tubing by lock bolt.

The utility model easy accessibility, can repeatedly use and repeat to install, but also is applicable to the construction repairing that pipeline burst leaks.
