Abstract
The invention, belonging to the technical field of pipeline connection, discloses a straight joint for rapidly connecting polypropylene random (PPR) and polybutylene (PB) pipes. The straight joint comprises two inserting ports (11) which are communicated with each other, wherein at least two grooves (12) are arranged on the inner walls of the inserting ports (11); sealing rings (2) and elastic clamping slices (3) are respectively arranged in the grooves (12). When in the use, the connection is finished just by stretching the pipes into the inserting ports (11); when the pipes are stretched into the inserting ports (11), the deformations of the elastic clamping slices (3) can be reduced to enable the pipes to be easy to mount; when the pipes are stretched out the inserting ports (11), the deformations of the elastic clamping slices (3) can be increased to enable the pipes to be difficult to pull out of the inserting ports (11), so that the connecting quality is guaranteed to prevent escaping easily; the sealing rings (2) are firmly sleeved on the outer surfaces of the pipes to realize a sealing connection with good effect, thereby avoiding the phenomenon of water leakage.
Description
Technical field
The invention belongs to the pipeline connection technology field, especially relate to a kind of PPR, the quick connection of PB tubing use straight coupling.
Background technique
Development along with new material technology; Pipeline material such as PPR, PB is widely applied to the industrial pipe-line systems such as hot and cold water pipeline system, purified water supply pipe-line system, central air-conditioner pipe-line 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 recyclable utilizations.
In the installation process of these pipe-line systems, often need tubing be linked together.Tubing has several different methods when connecting.The most frequently used Placement is to be threaded, but this mode receives the restriction of erection sequence and installing space, and is especially when the repairing pipe-line system, just very inconvenient sometimes.
For PPR, the interconnective method of PB tubing mainly is to utilize hot-melting machine to carry out hot melt to connect.But this welding process needs welder and welding supplementary equipment, and it is inconvenient that carrying device gets into site operation, and engineering cost is also than 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.
Summary of the invention
In order to solve the problem that exists in the above-mentioned existing technology, the present invention has designed a kind of PPR simply fast, the quick connection of PB tubing has used straight coupling.
Concrete scheme of the present invention is: a kind of PPR, PB tubing connect fast uses straight coupling, 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.
When using the straight coupling in this programme, only need that tubing is stretched into interface and can accomplish connection.When tubing stretches into interface, can 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 tightly is enclosed within pipe outer surface and realizes being tightly connected, and good sealing effect water leakage phenomenon can not occur.
Above-mentioned elastic card comprises the bending sheet that the integrated punching of tinsel body and linear interval arrangement above that is shaped; Pack into after the elastic card bending in the groove.
The hardness of above-mentioned tinsel is greater than the hardness of tubing, thereby makes the end of bending sheet snap in the outer surface of tubing.This is simple and reasonable, and elastic card has enough intensity and blocks tubing.
Above-mentioned elastic card generally adopts corrosion resistant plate muscle spare to make, and is preferably the SUS304 material.
For soundness and the sealing that increases connection, the quantity of above-mentioned groove is four, and wherein the cross section of two grooves is a rectangle, in establish elastic card; The cross section of two other groove is semicircle, in establish O-ring seals.
Direction of insertion along above-mentioned interface sets gradually: elastic card, elastic card, seal ring, seal ring.This mounting type can prevent that liquid from flowing to the elastic card place and influence the chucking effect of elastic card.
The present invention compared with prior art mainly has following beneficial effect: do not need special-purpose adhesive, engineering cost is low, and tubing is installed the influence 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 present invention is further specified.
As shown in Figure 1, a kind of PPR, PB tubing connect fast uses straight coupling, two interfaces that are interconnected 11, O-ring seals 2, elastic card 3.
Wherein interface 11 inwalls are provided with four grooves 12.For soundness and the sealing that increases connection, wherein the cross section of two grooves 12 is a rectangle, in establish elastic card 3; The cross section of two other groove 12 is semicircle, in establish O-ring seals 2.
Direction of insertion along interface 11 sets gradually: elastic card 3, elastic card 3, seal ring 2, seal ring 2.This mounting type can prevent that liquid from flowing to elastic card 3 places and influence the chucking effect of elastic card 3.
When using the straight coupling in this programme, only need that tubing is stretched into interface 11 and can accomplish connection.When tubing stretches into interface 11, can force the amount of deformation of elastic card 3 to dwindle, tubing is easy to pack into; When tubing was pulled out interface 11, elastic card 3 amount of deformation increased, and tubing is difficult to pull out, and quality of connection is relatively good, is not easy; Seal ring 2 tightly is enclosed within pipe outer surface and realizes being tightly connected, and good sealing effect water leakage phenomenon can not occur.
