Venturi tube : the scope and design of

Components device

design gets its name from its inventor John. Venturi.This device may be positioned in three spatial possible states: upright, horizontally or inclined, depending on the system requirements.Externally it resembles a tube which is flattened at one end.

This species has several pipeline elements constituents:

• Inlet with a number of holes in the form of an annular chamber and the slits for discharging pressure.
• inlet cone, which also has a slit for removal of the pressure.
• number of openings may vary depending on the gas or liquid obemopotoka.But, in turn, should be no less than four.

mounting device can be made in two types: normal and shortened.

Types Venturi tube

This device, depending on the inlet, can be of two types:

• With cast inlet, which is produced by casting in sand form without further processing.Processed only device elements such as the neck and round.
• With a cast hole that is processed after casting.The constituent elements are joined by welding.

Basic characteristics of the instrument

This type of tubular differs a certain number of specific features.

• during operation of the pipe in the pipe system of communications happening minimum pressure loss in the system.
• The tubular hardly accumulate different types of deposits.
• device has high wear resistance.
• Venturi tube is highly reliable operation.
• device is meant by a long service life.

venturi device is mainly used in major industrial facilities and have highly specialized functions.In everyday life it is unlikely to find the use of the action of the tube - except for tech hobby or small production.However, it should be noted that this article is so introductory theoretical intentionally - to try to implement the installation of the device on their own, especially if the experience of such work has not been previously - is fraught with serious accidents.Take care of yourself and trust the highly specialized activity only to professionals.

Thus, the article described the device function and scope of this type of tubulars as a venturi tube.
