Abstract
The utility model relates to a conversion joint for connecting a metal pipe and a nonmetal pipe. The conversion joint mainly solves the problem that the conventional pipes and flanges have poor connecting and sealing effects. The conversion joint is characterized in that: the outer cylindrical surface of a nonmetal converter (5) is provided with a positioning shaft shoulder (6) for connecting the nonmetal pipe, the cylindrical surface of a metal converter (3) is provided with an external thread for connecting the metal pipe, the shaft end of the metal converter (3) is provided with a positioning shaft shoulder (7), the thread end of the metal converter (3) passes through a step hole of the nonmetal converter (5), and the positioning shaft shoulder (7) is blocked on a step of the step hole in the nonmetal converter (5). The conversion joint can solve conversion and connection among the pipes with different materials and different calibers, and has the characteristics of tight seal and convenient installation.
Description
Technical field
The utility model relates to a kind of pipeline enclosure and connects crossover sub, and especially a kind of metal tube is connected crossover sub with nonmetallic pipe.
Technical background
Pipeline generally is used for the conveying of gas or liquid, and the variation along with carrying environment usually relates to mutual conversion and connectivity problem between the unlike material pipeline.The pipe end mounting flange is generally adopted in existing connecting means, connects with bolt between two flange plate.Yet because the material difference of pipeline enclosure, sealing effect is not good, usually leaks in the joint, has a strong impact on the transfer efficiency of pipeline internal medium, and befouling environment.
The model utility content
In order to solve the problem that existing piping flange connects the sealing effect difference, the utility model provides a kind of metal tube to be connected crossover sub with nonmetallic pipe.The conversion that this crossover sub can solve between the pipeline of various unlike materials, different bores connects, and has sealing characteristics tight, easy for installation.
The technical solution of the utility model is: a kind of metal tube is connected crossover sub with nonmetallic pipe, comprise the metal conversion part that has through hole and have in the nonmetal conversion part of shoulder hole, wherein, the location shaft shoulder when connecting nonmetallic pipe is arranged on the outer cylinder of nonmetal conversion part, have on the axial plane of metal conversion part in order to connect the outside thread of metal tube, its axle head has the location shaft shoulder, and the threaded end of metal conversion part passes the shoulder hole of nonmetal conversion part, and the location shaft shoulder of metal conversion part is stuck on the step of shoulder hole in the nonmetal conversion part.
Contacted position is equipped with seal ring between described metal conversion part and nonmetal conversion part; Described metal conversion part outside thread connects thin nut and metallic shim, and metallic shim contacts with the end face of nonmetal conversion part.
The beneficial effects of the utility model are: because this crossover sub two ends adopt is link between unlike material, connect with the pipeline of identical material respectively, thereby avoided connecting between the unlike material pipeline problem that sealing effect is not good, leakage takes place, and this joint structure is simple, easy to use, with low cost.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Extremely shown in Figure 4 by Fig. 1, this metal tube is connected crossover sub and comprises metal conversion part 3, nonmetal conversion part 5, seal ring 4, thin nut 1 and metallic shim 2 with nonmetallic pipe, wherein, in the nonmetal conversion part 5 shoulder hole is arranged, the location shaft shoulder 6 when connecting nonmetallic pipe is arranged, as shown in Figure 2 on the outer cylinder; In the metal conversion part 3 axial hole is arranged, have on the cylinder in order to connect the outside thread of metal tube, its axle head has the location shaft shoulder 7, as shown in Figure 3; After the threaded end of metal conversion part 3 passes the shoulder hole of nonmetal conversion part 5, and its location shaft shoulder 7 is stuck on the step of interior shoulder hole of nonmetal conversion part 5, and be equipped with seal ring 4 at metal conversion part 3 and 5 contacted positions of nonmetal conversion part, metal conversion part 3 outside threads connect thin nut 1 and metallic shim 2, metallic shim 2 is closely contacted with the end face of nonmetal conversion part 5, be used to compress seal ring 4, prevent the pipeline internal medium leakage, as shown in Figure 1.
When using this crossover sub, as shown in Figure 4, the threaded end that the metal conversion part 3 of seal ring 4 is housed is passed the shoulder hole of nonmetal conversion part 5, metallic shim 2 and thin nut 1 then successively are threaded on metal conversion part 3, thin nut 1 can be adorned 2, and with spanner it is tightened, make that the location shaft shoulder 7 is stuck on the interior shoulder hole of nonmetal conversion part 5 on the metal conversion part 3, make it compress seal ring 4 and fixing.Threaded end at metal conversion part 3 connects metal tube 8 by box cupling 9 then, the external diameter of nonmetal conversion part 5 inserts the endoporus of nonmetallic pipe, and the end face that makes nonmetallic pipe withstands on the location shaft shoulder 6 of nonmetal conversion part 5, connect at the end face of the location of nonmetal conversion part 5 shaft shoulder 6 and the molten plastic welding in end of nonmetallic pipe 10 then, as shown in Figure 4, so just can easily nonmetallic pipe closely be connected with metal tube, mutually conversion.
Because adopt at this crossover sub two ends is link between unlike material, connect with the pipeline of identical material respectively, thereby avoided the problem that sealing effect is not good, leakage takes place, and it is simple in structure, as installed is convenient, with low cost, the conversion between the different tubing of applicable multiple bore connects.
