Utility model content

This utility model is for deficiency, there is provided a kind of easy to connect, quick, reliable, and reusable oil flushing pipe Road.

The technical scheme that this utility model solves above-mentioned technical problem is as follows：A kind of oil flushing pipeline, including hose assembly And accessory part, the accessory part is installed in the two ends of the hose assembly, it is characterised in that the hose assembly includes glue Pipe and rubber hose coupling, the rubber hose coupling snaps onto respectively the two ends of the sebific duct, and the accessory part includes processing plate and company Connect a head, the first end connection rubber tube joint of the connecting filament, the other end connects the processing plate.

The beneficial effects of the utility model are：Connection is reliable, prevents oil leak, conveniently carries out oil flushing, reduces operating cost.

On the basis of above-mentioned technical proposal, this utility model can also do following improvement.

Further, two of the connecting filament head is equipped with connection screw thread, by the connection screw thread respectively with processing plate With rubber hose coupling connection.

It is using the beneficial effect of above-mentioned further scheme, it is easy to connect, quick.

Further, the connecting filament head includes that described pipe collar one end is welded on the connecting plate, another to silk and pipe collar End is threadedly coupled with described to silk.

Further, the first end of the connecting filament is provided with connection screw thread, is connected with rubber hose coupling by the connection screw thread, institute The other end for stating connecting filament head is welding ends, is welded on the processing plate.

Further, the rubber hose coupling includes leading directly to JIC74 ° of (Unite States Standard conical surface seal screw thread) rubber hose coupling and 90 ° JIC rubber hose couplings.

Further, the pipe collar is NPT (60 ° of taper pipe threads of Unite States Standard) female thread pipe collar.

Further, the processing plate is screwed flange.

Specific embodiment

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit scope of the present utility model.

As Figure 1-3, a kind of oil flushing connecting pipe, including hose assembly and accessory part 3, the accessory part peace The two ends of the hose assembly are mounted in, the hose assembly includes sebific duct 1 and is connected to the rubber hose coupling 2 at the sebific duct two ends, The rubber hose coupling 2 snaps onto respectively the two ends of the sebific duct 1, and the accessory part 3 includes processing plate 6 and connecting filament head 7, institute State one end connection rubber tube joint 2 of connecting filament head 7, the other end connection processing plate 6.

Two of the connecting filament head 7 is equipped with connection screw thread, by the connection screw thread respectively with processing plate 6 and sebific duct Joint 2 connects, shown in such as Fig. 3 (d)；The connecting filament head includes that to silk 9 and pipe collar 8 one end of the pipe collar 8 is welded on described adding On work plate plate, the other end is threadedly coupled with the rubber hose coupling 2, shown in such as Fig. 3 (c)；Described one end of connecting filament head 7 is provided with connection Screw thread, is connected by the connection screw thread with rubber hose coupling 2, and the other end of the connecting filament head 7 is welding ends, is welded on described On processing plate 6, such as Fig. 3 (a) and Fig. 3 (b)；The rubber hose coupling includes straight-through JIC rubber hose couplings 4 and 90 ° of JIC rubber hose couplings 5, Respectively as shown in Fig. 2 (a) and Fig. 2 (b)；The pipe collar 8 is NPT female thread pipe collars；The processing plate 6 is screwed flange 10.
