Abstract
The utility model belongs to the technical field of ventilation utensils, and particularly relates to a ventilation pipe. The utility model discloses the ventilation pipe, which comprises a plurality of pipelines provided with vents at same portions, connection covers matched with the vents are arranged on the vents, and the opening at one end, far away from the corresponding vent, of each connection cover is larger than the corresponding vent. The ventilation pipe provided by the utility model can be used for multiple purposes, the use efficiency is improved under the condition that the resources are saved, the use effect is enhanced at the same time, and the service life is prolonged.
Description
Technical field
The utility model belongs to ventilation apparatus technical field, relates in particular to a kind of ventilation duct.
Background technique
Very general of the application of ventilation duct in manufacturing enterprise, particularly the ventilation of each equipment is used in manufacturing shop.The ventilation duct that uses now generally all is that a tubular body is adding a ventilated port, and the ventilation duct of this type can only be man-to-man use.When having a plurality of equipment or a plurality of place need to use ventilation duct in the manufacturing shop, just need a plurality of ventilation ducts are installed, so not only occupy very big space, and use and manage very inconvenience.
Summary of the invention
The purpose of the utility model is to solve above-described technical problem, and a kind of ventilation duct is provided, and its technological scheme is following:
A kind of ventilation duct; Described this ventilation duct is made up of some pipe joints road; The same position of described pipeline offers ventilated port, and described ventilated port is provided with ventilated port is complementary and is connected cover, said connection cover away from the opening of an end of ventilated port greater than ventilated port.
Optimal way is that described pipeline is provided with stiffening ring.
The utility model is provided with a plurality of ventilated ports, makes same ventilation duct to be used by a plurality of places that need to ventilate.Be provided with simultaneously with ventilated port is complementary and be connected cover, connect cover away from the opening of an end of ventilated port greater than ventilated port, can better reach the effect of ventilation.
The utility model is provided with stiffening ring can strengthen the adhesive strength between each pipeline, can increase the working life of ventilation duct.
The utility model can one tube multipurpose, has saved under the situation of resource and has also improved utilization efficiency, has strengthened the effect of using simultaneously, has increased the life-span of using.
