Description

A kind of pipeline four-way

Technical field

This utility model relates to pipe technology field, a kind of anti-blocking pipeline four-way.

Background technology

General four-way generally includes threeway, sleeve pipe, elbow are directly connected with pipe fitting, if there is blocking, only uses the mode of dredging to dredge, but typically tee T angle is vertical, or more low-angle, is unfavorable for dredging.

Summary of the invention

For solving the problems referred to above, this utility model provides a kind of anti-blocking pipeline four-way, including: sleeve pipe, elbow, four-way pipe, threeway head, two-way head, one leads to head, is provided with anti-blocking pipe box on threeway head, it is characterized in that, described threeway head and described anti-blocking sleeve pipe arrange the service hatch of a pair correspondence.Described anti-blocking sleeve pipe hank knotting is screwed in the first end of threeway.

This utility model is by increasing the service ports of a pair correspondence, and when four-way is unimpeded, anti-blocking sleeve pipe misplaces with threeway head service ports, it is ensured that pipeline closes.When four-way blocks, anti-blocking sleeve pipe is corresponding with threeway head service ports, it is simple to dredging.Described anti-blocking sleeve pipe hank knotting is screwed on threeway head, and dredging becomes convenient.
