The valve assembly of corrugated pipe corrugated pipe and valve.

摘要

The valve assembly of corrugated pipe corrugated pipe valve. An assembly of a corrugated pipe and corrugated pipe seal assembly is disclosed.The assembly of the seal corrugated pipe corrugated pipe comprises an inner (3), a corrugated external pipe (4), an upper tubular connection (5), a first lower tubular connection (2) and a second connection tubular lower (1).One end of the corrugated pipe internal (3) u00e9fixada with connecting corrugated tubular upper (5), as the other end is fixadacom the second tubular connection less (1). One end of the outer tube corrugated board (3) is fixed with the upper corrugated tubular connection (5), while the other end is fixed with the first connection tubular lower.The outer tube (4) is concealed by the corrugated pipe corrugated internal (3). The assembly of the corrugated pipe corrugated pipe sealed and the valve have the advantages of rational structural design, saving material costs, shortening the length of the valve, eencurtando course switch valve, and are comparatively favourable for sites with Lim Ites of the time.
