Description

Novel civil air defense reducer pipe

Technical field

It the utility model is related to a kind of reducer pipe, more particularly to a kind of Novel civil air defense reducer pipe.

Background technology

Reducer pipe is one of the most frequently used pipe fitting.It is commonly used for conveying some special fluids or gas in civil air defense constructions and installations Body.In transportation, in the bending place of pipeline, due to the long-term impulse piping wall of fluid, piping failure is easily caused so that interior Portion's fluid is revealed, and endangers the safety of whole civil air defense constructions and installations.

Utility model content

The utility model embodiment technical problem to be solved is, is being passed for the reducer pipe in present civil air defense constructions and installations During defeated, bending place is impacted by internal flow for a long time, easily damaged situation, it is proposed that a kind of Novel civil air defense reducing Pipe.

In order to solve the above-mentioned technical problem, the utility model embodiment provides a kind of Novel civil air defense reducer pipe, and this is new People's air defense reducer pipe includes：Enter pipe, expansion section, kink, gathering portion and outlet pipe, it is described enter pipe, the expansion section, the bending Portion, the gathering portion and the outlet pipe are sequentially communicated, it is described enter pipe other end connection first flange, the outlet pipe other end connects Connect second flange, the expansion section is truncated rectangular pyramids type, and gathering portion side is circular arc, the kink connected by folded plate and Into.

Wherein, it is described enter pipe side for square.

Wherein, the outlet pipe side is circle.

Wherein, the expansion section, the kink and gathering portion junction are provided with a reinforcement.

Wherein, the kink bending angle is 90 °.

Implement the utility model embodiment, have the advantages that：Novel civil air defense reducer pipe provided by the utility model Using Newer designs, during fluid is transmitted, impact of the fluid for tube wall is effectively reduced, extends making for reducer pipe With the life-span, the reliability of equipment is improved.
