Description

Technical Field

[0001] The utility model relates to the technical field related to pipe fitting connection, in particular to an overflow glue storage type PPR pipe fitting. Background Art

[0002] PPR pipe fittings are the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipes. They are made by hot melting, have special welding and cutting tools, and have high plasticity.

[0003] Most of the existing PPR pipe fittings are connected to pipes by hot-melt socket connection, that is, a special heating mold for PPR pipes and pipe fittings is used to heat the outer surface of a section of pipe and the inner surface of another section of the pipe fitting connection body at the same time. After the heating time is over, one section of the pipe and the other section of the pipe fitting connection body are pulled out of the heating mold, and one section of the pipe is quickly inserted into the socket of the other section of the pipe fitting connection body and inserted into the pre-marked position. At this time, excess adhesive will overflow from the connection between the two sections of the pipe fitting, and the overflowed adhesive is squeezed into the pipe section, thereby reducing the inner diameter of the pipe and increasing the water flow resistance. In order to solve this kind of problem, a PPR pipe fitting with overflow glue storage is proposed. Utility Model Content

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0022] Reference Figure 1 and Figure 2As shown, PPR pipe fittings are the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipes. They are connected by hot-melt welding, have special welding and cutting tools, and have high plasticity. Most of the existing PPR pipe fittings are connected to pipes by hot-melt socket welding, that is, a special heating mold for PPR pipes and pipe fittings is used to heat the outer surface of a section of the pipe and the inner surface of the other section of the pipe fitting connection body at the same time. After the heating time is over, one section of the pipe and the other section of the pipe fitting connection body are pulled out of the heating mold, and one section of the pipe is quickly inserted into the socket of the other section of the pipe fitting connection body, and inserted into the pre-marked position. At this time, excess adhesive glue will overflow from the connection between the two sections of the pipe fittings, and the overflowed glue will be squeezed into the pipe section, thereby reducing the inner diameter of the pipeline and increasing the water flow resistance. In order to solve this problem, a glue overflow storage type PPR pipe fitting is proposed, including a butt-joined pipe group, wherein the butt-joined pipe group includes a first pipe fitting 11 and a second pipe fitting 12 that are sleeved and connected to each other at a section close to each other, and the first pipe fitting 11 is shrunk on the outer circumference of a section close to the second pipe fitting 12 to form A step block 112 for coating the outer periphery with adhesive, a second pipe 12 is concave on the inner periphery of one side close to the step block 112 to form a slot 122, an anti-overflow component 2 is provided between the slot 122 and the step block 112, the anti-overflow component 2 includes an anti-overflow baffle 22 provided in the slot 122 and concentrically arranged with the second pipe 12, the step block 112 and the anti-overflow baffle 22 are provided with a limit groove for the anti-overflow baffle to be inserted into to prevent the adhesive from entering the butt joint pipe assembly 21; The arrangement of the stepped block 112 and the slot 122 in the first pipe fitting 11 and the second pipe fitting 12 can achieve orderly docking of the butt joint assembly, and the arrangement of the anti-overflow baffle 22 and the limiting groove 21 in the anti-overflow component 2 can achieve that when a section of the first pipe fitting 11 is inserted into the second pipe fitting 12, the anti-overflow baffle 22 cooperates with the limiting groove 21 to prevent the adhesive on the outer periphery of the stepped block 112 from flowing inwardly into the flow space of the pipe fitting, thereby achieving the purpose of protecting the flow space in the butt joint assembly.

[0023] It should be noted that the area on the outer periphery of the stepped block 112 coated with adhesive, that is, when the first pipe 11 is inserted into the second pipe 12, the outer periphery of the stepped block 112 and the inner periphery of the slot 122 are attached to each other, and the connecting tube assembly can be connected at this time.

[0024] Furthermore, the first pipe fitting 11 and the second pipe fitting 12 are preheated before being inserted into the sleeve, that is, the adhesive and the first pipe fitting 11 and the second pipe fitting 12 are in a better bonding state. When the anti-overflow baffle 22 is inserted into the limiting groove 21, the adhesive cup anti-overflow baffle 22 on the outer periphery of the step block 112 resists and cannot flow into the pipe fitting.

[0025] Furthermore, in order to better prevent the adhesive from overflowing, in the present embodiment, the anti-overflow baffle 22 is arranged in a circular ring shape to cooperate with the limiting groove 21; the anti-overflow baffle 22 is arranged in a circular ring shape to ensure that during the docking process of the entire second pipe fitting 12, the adhesive on the outside can be effectively blocked on the outside, thereby also being able to meet the purpose of making the adhesive at the attachment point of the first pipe fitting 11 and the second pipe fitting 12 more complete.

[0026] It should also be noted that PPR pipe fittings are mostly used to transmit some liquid solutions. Specifically, the first pipe fitting 11 and the second pipe fitting 12 are respectively provided with a first transmission groove 111 and a second transmission groove 121 for liquid flow; the arrangement of the first transmission groove 111 and the second transmission groove 121 can make the internal functions of the PPR pipe fittings relatively complete.

[0027] Furthermore, the diameter lengths of the first transmission groove 111 and the second groove are the same, thus ensuring the subsequent transmission effect.

[0028] Furthermore, in order to achieve a better anti-overflow effect for the entire docking tube assembly during the docking process, in the present embodiment, a plurality of overflow storage grooves for storing excess adhesive are provided on the inner peripheral wall of the slot 122 and are spaced in sequence along the transmission direction of the second pipe fitting 12; by providing a plurality of overflow storage grooves, when the first pipe fitting 11 is inserted into the second pipe fitting 12, the excess adhesive will enter the overflow storage groove as the first pipe fitting 11 is inserted, and since the adhesive part is connected, the connection effect between the first pipe fitting 11 and the second pipe fitting 12 will be better.

[0029] It is worth mentioning that the stepped block 112 is located on the outer side of the first pipe 11 and is concave to form a connecting groove for improving the bonding effect of the connecting pipe group; through the setting of the connecting groove, the adhesive at the screenshot block can better connect the first pipe 11 and the second pipe 12.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manner derived by those skilled in the art based on the technical solution of the present invention also falls within the scope of protection of the present invention.
