Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail。The present embodiment is carried out premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment。
A kind of plastic pipe outer flow passage calibration sleeve, as shown in Figures 1 to 5, including water distribution seat 3 and calibration sleeve 9, water distribution seat 3 is provided with inlet opening, and outer flow passage calibration sleeve also includes pressing plate 2 and flange 6, and water distribution seat 3 is fixed by pressing plate 2 and flange 6 in calibration sleeve 9 from both sides, and with form the outer flow passage that connects with inlet opening between calibration sleeve 9, after cooling water enters from water inlet, flow into outer flow passage, and form moisture film in calibration sleeve outer wall。
Outer flow passage calibration sleeve also includes the internal ring 5 being sheathed between water distribution seat 3 and calibration sleeve 9, forms the storage chamber connected with outer flow passage between this internal ring 5 with water distribution seat 3。
Inlet opening is provided with the trachea socket 4 for connecting inlet pipeline。
Calibration sleeve 9 outer wall is additionally provided with outer flow passage extension, and one end of outer flow passage connects with storage chamber, and the other end connects with outer flow passage extension, and outer flow passage extension is identical with the external diameter of outer flow passage。In FIG, it is possible to know that outer flow passage extension is outer flow passage naturally extending in the unexpected part of water distribution seat 3 and flange 6。
