Abstract
The utility model is related to a kind of reducing and seamlessly transits direct conduit coupling, the connector has the middle interconnecting piece of one first connectivity port, second connectivity port relative with first connectivity port and the connection first port and the second port, first connectivity port is different with the caliber size of the second connectivity port, the middle interconnecting piece by first connectivity port to second connectivity port or the middle interconnecting piece by second connectivity port to first connectivity port be in a ramp structure seamlessly transitted.Reducing is directly connected to be connected smoothly at the internal forwarding of part size connectivity port by the utility model, form the descending or ascending cambered surface connection of bore, impact and the resistance of liquid flowing are significantly reduced, while also eliminating the noise produced in pipeline due to the excessive impact of liquid flowing pressure.
Description
Technical field
The utility model is related to one kind to, draining, the improvement of the conduit coupling structure such as supply, is specifically related to one kind
The structure of the direct conduit coupling of reducing is improved, the resistance of current in the pipeline that takes this to improve.
Background technology
In the construction of water supply and sewerage pipeline, according to the need for pipeline function or the need for easy construction, it usually needs will be each
Individual associated pipe connection, in connection procedure, there is also the inconsistent situation of caliber, at this moment needs reducing directly by two differences
The pipeline connection intercommunication of caliber.
Original direct conduit coupling of reducing is all the simple pipe fitting concentric reducer different using two footpath mouthful, to connect respectively
Connect the pipeline of two different tube diameters.The problem of so causing is in the directly internal formation one due to two cause not of uniform size of reducing
Individual obvious step（Boss）, as shown in figure 1, this step inside pipeline equivalent to the mutation for having a caliber, make liquid flow
Dynamic formation very big impact and resistance.
The content of the invention
For above the deficiencies in the prior art, the purpose of this utility model is directly to carry out structural change to existing reducing
Enter, propose that a kind of reducing of inside without boss is directly connected to part structure accordingly, efficiently solve the problem of prior art presence.
The technical solution adopted in the utility model is：
A kind of reducing seamlessly transits direct conduit coupling, the connector have one first connectivity port, one with this first
The second relative connectivity port of connectivity port and the middle interconnecting piece of the connection first port and the second port, this first
Connectivity port is different with the caliber size of the second connectivity port, it is characterised in that：The middle interconnecting piece is by first connection end
It is in one flat to first connectivity port mouthful to rise to second connectivity port or the middle interconnecting piece by second connectivity port ing
Slip over the ramp structure crossed.
The first described connectivity port includes non-threaded connectivity port, or with internal thread or externally threaded connection
Port.
The second described connectivity port includes non-threaded connectivity port, or with internal thread or externally threaded connection
Port.
The reducing that the utility model is provided seamlessly transits direct conduit coupling, and reducing is directly connected into part size connection end
It is connected smoothly at the internal forwarding of mouth, forms the descending or ascending cambered surface connection of bore, change existing
There is the internal structure of projective table type, completely solve in place of foregoing the deficiencies in the prior art, significantly reduce the impact of liquid flowing
And resistance, while also eliminating the noise produced in pipeline due to the excessive impact of liquid flowing pressure.
Brief description of the drawings
Fig. 1 is the direct conduit coupling structure cut-away view of existing reducing；
Fig. 2 is the utility model example structure schematic diagram；
Fig. 3 is Fig. 2A-A to cross-sectional view.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described in detail in embodiment of the present utility model：
Fig. 2, Fig. 3 are referred to, the reducing that the present embodiment is provided seamlessly transits direct conduit coupling, is normally used for size
Adaptor between the different pipeline connection of bore, it has one first connectivity port 1, one relative with first connectivity port
Second connectivity port 2 and the middle interconnecting piece 3 for connecting the first port 1 and the second port 2, the He of the first connectivity port 1
The caliber size of second connectivity port 2 is different.The middle interconnecting piece 3 is by first connectivity port 1 to second connectivity port
2 or the middle interconnecting piece 3 by second connectivity port 2 to first connectivity port 1 be in an inclined-plane knot seamlessly transitted
Structure.From Fig. 2 and Fig. 3, the aperture of middle interconnecting piece 3 that the first connectivity port 1 and the second connectivity port 2 are linked into an integrated entity from
Arrive greatly small（Or from small to large）In smooth inclined-plane, be by first connectivity port 1 towards the second connectivity port 2 or by
Second connectivity port 2 is seamlessly transitted towards first connectivity port 1, is not the structure straight up and down of step.Centre connection
One end bore of portion 3 is connected with the bore of the first connectivity port 1, and other end bore is then connected with the bore of the second connectivity port 2.
Wherein, the first connectivity port 1 and the second connectivity port 2 can be non-threaded connectivity ports or with interior
Screw thread or externally threaded connectivity port.
Claims (3)
