Abstract
The utility model relates to a connecting pipe fitting, in particular to a different diameter connecting piece which comprises a connecting pipe and assembling pipes fixedly connected with two ends of the connecting pipe, wherein the connecting pipe is formed by fixedly connecting of a thick pipe, a transitional pipe and a thin pipe in sequence, limiting rings are arranged on the joint of the transitional pipe and the thick pipe and on the joint of the transitional pipe and the thin pipe inside the connecting pipe, and the limiting rings are in arc transition with the transitional pipe. Therefore, noise influences brought by gaps existing between two different diameter pipe fittings which are connected mutually or steps in the process of different diameter pipe fitting connection are eliminated, generation of the phenomenon of pipeline blocking caused by the fact that impurities are prone to deposition due to channel resistance formed by the gaps or the steps is avoided, and overall sealing performance is improved.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, is specifically related to a kind of reducing link.
Background technique
Drainage pipe application in daily life is very extensive, at industrial premises, the connection of reducing pipeline is often used in the water supply and sewerage pipeline of indoor and outdoors such as civil building, modes such as spigot and socket type carry out and the connection of present reducing fittings typically uses, in these Placements, because the external diameter difference of two pipe fittings that connect, cause between the connecting end of two pipe fittings, can not directly contacting, make and between the connecting end of two reducing fittings and socket pipe member, form a step, this step has caused obstruction for the fluid in the pipeline, and make the fluid in the pipeline increase noise because of access denial generation turbulent flow, if containing foreign material in the fluid also can cause the foreign material deposition and then cause pipe blocking, on the other hand, reducing fittings links to each other also because there is the bad problem of integral sealing effect in existing Placement deficiency.
A kind of clamp band type reducing coupling pipe by name, an application number are that 201120415465.5 utility model patent discloses a kind of reducing coupling pipe, it is made by metallic material, comprise body, clip spare, body is a round platform tubular structure left large and right small, two sides, left and right sides opening, clip spare is that outer imperial palace is little, the centre is with the round hoop formula part of a bar shaped notch, each one of clip spare size is provided with round mouth outer end, the body left and right sides respectively and connects firmly with it.Though this reducing coupling pipe can connect two pipe fittings of various outer diameter, does not solve hereinbefore described problem.
The model utility content
The purpose of this utility model is in order to solve present pipeline reducing fittings in connection procedure, because two pipe fitting external diameter differences that are connected make two pipe fittings directly not contact, cause between the connecting end of two pipe fittings and link and form step, the last problem of bringing noise easily and causing foreign material deposition formation pipeline obstruction in the pipeline easily provides a kind of reducing link.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of reducing link, comprise connecting tube and the assembling pipe that is connected with the connecting tube two ends, described connecting tube is connected successively by extra heavy pipe, transition tube and tubule and forms, extra heavy pipe, transition tube and tubule are connected successively, the two ends of transition tube all are installed with limited ring, the two ends inwall arc-shaped transition of limited ring and transition tube.
Two limited rings are set in connecting tube, and after two limited rings and the transition tube arc-shaped transition, when outer tube is inserted connecting tube, the end of two pipe fittings will contact with the limited ring on both sides respectively, thereby reached the space of filling up between interconnective two outer tube, eliminate outer tube in connecting tube with the purpose of the step that is connected tube wall formation, and then prevented the formation of the noise that space or step cause tube fluid, avoid the existence of step to cause the generation of the line clogging phenomenon that the deposition of foreign material in the fluid causes, also improved sealing effect simultaneously.
As preferred version, described limited ring is a vertical surface away from the end face of transition pipe end, and the height of limited ring end face matches with the wall thickness of the extraneous pipe fitting that is connected.The end face of limited ring can coincide with the end face of external pipe fitting like this, thereby better eliminates the slit, avoids the generation of step.
As preferred version, the internal diameter of described assembling pipe is greater than the external diameter of the connecting tube end that is attached thereto, and the assembling pipe forms step respectively with the joint, two ends of connecting tube, the step place is provided with seal ring, the termination of assembling pipe is provided with friction top, and friction top is provided with snap ring, friction top and connecting tube clamping.The combination of friction top and seal ring can seal the outer tube of inserting in the connecting tube more, and is more firm.Friction top is reusable simultaneously, has increased the secondary practicability of reducing link.
As preferred version, described seal ring is provided with anti-skidding line.Can increase sealing.
As preferred version, the joint arc-shaped transition of described extra heavy pipe and transition tube, the joint arc-shaped transition of transition tube and tubule.Arc-shaped transition can prevent to wipe bumps the breakage that causes link, increases the link bulk strength from another point of view.
Owing to adopt technique scheme, the beneficial effects of the utility model are: (1) has been eliminated reducing fittings and be formed at the influence of noise that space between interconnective two reducing fittings and the link or step bring in connection procedure, (2) channel resistance of having avoided these spaces or step to form causes foreign material to deposit the generation of the phenomenon that causes line clogging easily, (3) and for pipe interior provide a good fluid passage, increased sealing effect, effect is better when especially being applied to electric melting pipe fittings.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1 connecting tube, 2 assembling pipes, 3 extra heavy pipes, 4 transition tube, 5 tubules, 6 limited rings, 7 steps, 8 seal rings, 9 friction tops, 10 snap rings.
Embodiment
With specific embodiment the utility model is further described below.
Embodiment
A kind of reducing link, as shown in Figure 1, comprise connecting tube 1 and with the assembling pipe 2 at connecting tube 1 two ends, connecting tube 1 and assembling pipe 2 structure that is formed in one, assembling pipe 2 two ends all dispose and assemble pipe 2 seal rings that match 8 and friction top 9; Connecting tube 1 is made up of extra heavy pipe 3, transition tube 4 and tubule 5, extra heavy pipe 3, transition tube 4 and tubule 5 link to each other and successively in the joint arc-shaped transition, the joint that is positioned at transition tube 4 and extra heavy pipe 3 and tubule 5 in the connecting tube 1 all is provided with limited ring 6, and arc-shaped transition between limited ring 6 and the transition tube 4, the wall thickness of limited ring 6 matches with the wall thickness of the extraneous pipe fitting that is connected, thereby better eliminates the existence of step; The internal diameter of assembling pipe 2 is greater than the external diameter of connecting tube 1 end that is attached thereto, thereby the joint, two ends at assembling pipe 2 and connecting tube 1 forms step 7 respectively, and assembling pipe 2 is shunk to the port by step 7 places, seal ring 8 is provided with anti-skidding line, and seal ring 8 is positioned on the step 7 of connecting tube 1 so that sealing is filled in the space between assembling pipe 2 and outer tube, the inwall end of friction top 9 is provided with snap ring 10, thereby friction top 9 is further fixed the outer tube of inserting in the connecting tube 1 by the snap ring 10 and step 7 clampings of connecting tube 1 outer wall.
