Abstract
The utility model belongs to the technical field of pipeline connection and discloses a bend for rapid connection of different pipes. The bend comprises two mutually communicated insertion openings (11), at least two grooves (12) are arranged on the inner wall of each insertion opening (11), and a sealing ring (2) and elastic clamping pieces (3) are arranged in each groove (12). The bend is used only by extending the pipes into the insertion openings (11) so that connection can be completed. When the pipes extend into the insertion openings, the deformation amount of the elastic clamping pieces (3) are forced to be reduced, so that the pipes are mounted quite easily; and when the pipes are pulled out of the insertion openings (11), the deformation amount of the elastic clamping pieces (3) is increased, the pipes are pulled out quite difficultly, connection quality is good, and the pipes are less prone to abjection. The sealing rings (2) are sleeved on the outer surface of the pipes tightly to achieve sealing, so that sealing effect is good, and water leakage can be avoided.
Description
Technical field
The utility model belongs to the pipeline connection technology field, especially relates to fast connection elbow of a kind of different tubing.
Background technique
Development along with new material technology, the pipeline materials such as PVC-U, PPR, PB are widely applied to the industrial pipe-line systems such as cold hot water piping system, purified water supply pipe-line system, central air-conditioning pipe system, conveying or discharging chemical mediator of building because advantages such as low, the long service life of its thermal conductivity, good heat resistance, corrosion-resistant, non-scaling, health, nontoxic and recoverables.
In the installation process of these pipe-line systems, often tubing need to be linked together.Tubing is connected with several different methods.The most frequently used Placement is to be threaded, but this mode is subjected to the restriction of tubing specification, erection sequence and installing space, and is especially when the repairing pipe-line system, sometimes just very inconvenient.
Another connecting means is that the material use adhesive according to tubing bonds.But the used adhesive of this kind connecting means is chemical substance, during use naked light can not be arranged, and prevents fire risk, also can be dangerous when being strayed into eyes because of carelessness when the workmen uses; And need to use with the opening, the time that puts length will cause solidifying, cause waste; In addition, below-10 degree, should not construct, surpass 24 hours ability after the construction and use; Adhesive is smeared inhomogeneous, and bond effect is bad, water leakage phenomenon can occur.
Also having a kind of method is to carry out hot melt with hot-melting machine to connect.This welding process needs welder and welding supplementary equipment, and carrying device enters the site operation inconvenience, and engineering cost is also higher.The welding material hot melt that needs a person with the qualifications of a general, consuming time long, power consumption is many, and working efficiency is the end relatively.If inhomogeneous during hot melt, the welding effect is bad, water leakage phenomenon can occur.
But when different tubing connect, as PVC-U tubing be connected with PPR tubing, PVC-U tubing is connected with PB tubing, just cumbersome when PPR tubing is connected with PB tubing.
The model utility content
In order to solve above-mentioned problems of the prior art, the utility model has designed a kind of connection, and quick connection of simple different tubing used elbow fast.
Concrete scheme of the present utility model is: a kind of different tubing connect fast uses elbow, comprises two interfaces that are interconnected, and described interface inwall is provided with two grooves at least, is respectively equipped with seal ring and elastic card in the groove.
During joint in using this programme, only need that tubing is stretched into interface and can finish connection.When tubing stretches into interface, force the amount of deformation of elastic card to dwindle, tubing is easy to pack into; When tubing was pulled out interface, the elastic card amount of deformation increased, and tubing is difficult to pull out, and quality of connection is relatively good, is not easy; Seal ring is tightly placed in pipe outer surface and realizes being tightly connected, and good sealing effect water leakage phenomenon can not occur.
Above-mentioned elastic card comprises tinsel body and the bending section of integral type, and wherein bending section is provided with at least two breach along the bending line direction; Pack into after the elastic card bending in the groove.Because the hardness of elastic card is greater than the hardness of tubing, thereby make the end of bending section snap in the outer surface of tubing.This is simple and reasonable, and elastic card has enough intensity and blocks tubing.Elastic card generally adopts stainless steel material to make, and is preferably the SUS304 material and makes.
For soundness and the sealing that increases connection, the quantity of above-mentioned groove is four, wherein in three grooves elastic card is set respectively, in another groove seal ring is set.
Each above-mentioned interface sets gradually along direction of insertion: elastic card, elastic card, elastic card, seal ring.This mounting type can prevent that liquid from flowing to the elastic card place and affect the chucking effect of elastic card.
The end of above-mentioned bending section is tip-angled shape or is flexuose, makes its easier surface that snaps in tubing.
The part of above-mentioned joint except seal ring and elastic card adopts PVC-U, PPR, the direct molding and forming of PB material, and processing is simple, and is with low cost.
The utility model compared with prior art mainly has following beneficial effect: do not need special-purpose adhesive, engineering cost is low, tubing is installed the impact that needn't consider ambient temperature, pipe-line system is in the repairing process, directly the pipeline connection is got final product, and can use at once, need not wait until adhesive solidification, quick and easy for installation, efficient is high.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of different tubing connect fast uses elbow, comprises two interfaces that are interconnected 11, seal ring 2 and elastic card 3.
Wherein interface 11 inwalls are provided with four grooves 12, three groove 12 interior elastic cards 3 that arrange respectively wherein, another groove 12 interior seal rings 2 that arrange.Its arrangement mode is: be followed successively by along direction of insertion: elastic card 3, elastic card 3, elastic card 3, seal ring 2.This mounting type can increase soundness and the sealing of connection, and can prevent liquid from flowing to elastic card 3 places and affect the chucking effect of elastic card 3.
As shown in Figures 2 and 3, elastic card 3 comprises tinsel body 31 and the bending section 32 of integral type, and wherein bending section 32 is provided with five breach along the bending line direction; Pack into after elastic card 3 bendings in the groove 12.Because the hardness of elastic card 3 is greater than the hardness of tubing, thereby make the end of bending section 32 snap in the outer surface of tubing.This is simple and reasonable, and elastic card 3 has enough intensity and blocks tubing 2.The elastic card 3 general stainless steel materials that adopt are made, and are preferably the SUS304 material and make.
As shown in Figure 3, the end of the bending section 32 of present embodiment is tip-angled shape or is flexuose, makes its easier surface that snaps in tubing.
