Description

Circulation pipeline throttling structure

Technical Field

The utility model relates to a metal adds oil pipe field, specifically is a circulation pipeline throttle structure.

Background

The working principle of the circulating pipe is as follows: by virtue of the venturi effect, the circulation tube receives a portion of the gas discharged from the tank and the gas flow rate increases as its section through the tube decreases abruptly. A low pressure is generated near the gas flowing at a high speed, thereby generating adsorption.

The existing scheme is to plug a metal block with a specific aperture size into a small circulation pipe. The defect is that a step structure exists in the pipe, and when gas with coating materials passes through the pipe, coating accumulation is easily generated at the step, so that small holes are blocked; the hose is externally connected with a hose with a specific pipe diameter, and the defect is that the structure is complex; the cost is increased; the commonality is not strong, and different trend need the different hoses of adaptation to add oil pipe.

Therefore, a circulation pipeline throttling structure is designed.
