Abstract
The utility model discloses an airflow direction detects auxiliary device, including takeover and outlet duct, the outlet duct end is provided with the gas outlet, and the takeover front end is connected with air inlet interface, and it has a plurality of ventholes to follow axis evenly distributed on the outlet duct, is provided with the internal thread in the outlet duct, and the terminal fixedly connected with inner tube of ventilating of takeover is provided with the external screw thread outside the inner tube of ventilating, and internal thread and screw-thread fit, the inner tube of ventilating pass through threaded connection with the outlet duct. The connecting pipe of the auxiliary airflow flow direction detection device is communicated with the output pipe of the smoke generator through the air inlet connector, and the airflow flow direction is detected by aligning the air outlet of the air outlet pipe to the detection port. Simultaneously, the air outlet pipe is screwed out by rotating the air outlet pipe, the air outlet hole is aligned to the detection port of the whole linear position, the air flow direction of the whole linear position can be detected simultaneously, and the detection and observation are more convenient.
Description
Technical Field
The utility model relates to an air current flow direction detection area especially relates to an air current flow direction detects auxiliary device.
Background
The positions of the air supply outlet and the air exhaust outlet in the clean room relative to a pollution source, a heat source and an airflow barrier are very important for pollution control, and products and personnel can be protected by adjusting the positions of the tail air supply outlet and the tail air exhaust outlet. The positions of the air supply opening and the air exhaust opening are adjusted, the flow direction of the air flow needs to be determined by means of an air flow test product, and the air flow direction in the clean room is ensured to be unidirectional.
Existing airflow tests typically emit smoke through a smoke generator to a designated point through a pipe and then observe the flow of the smoke toward a confirmation detection point. However, the conventional detection device can only detect the airflow direction at a single position, and cannot observe the airflow direction at multiple positions on the same straight line or even the airflow direction at the position of the whole straight line.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model relates to an airflow direction detects auxiliary device.
The utility model adopts the following technical scheme:
the utility model provides an airflow direction detects auxiliary device, includes takeover and outlet duct, and the outlet duct end is provided with the gas outlet, and the takeover front end is connected with the interface of admitting air, has a plurality of ventholes along axis evenly distributed on the outlet duct, is provided with the internal thread in the outlet duct, and the terminal fixedly connected with inner tube of ventilating of takeover is provided with the external screw thread outside the inner tube of ventilating, and internal thread and external screw thread fit, the inner tube of ventilating pass through threaded connection with the outlet. The connecting pipe is communicated with the output pipe of the smoke generator through an air inlet interface.
Preferably, the air outlet is a bell mouth.
Preferably, an internal thread is provided in the air inlet interface.
Preferably, the connecting pipe and the ventilation inner pipe are vertically and fixedly connected.
Preferably, the air outlet pipe is provided with scales. The structure is convenient for aligning the detection position to discharge smoke and detect the flow direction of the airflow.
The utility model has the advantages that: the connecting pipe of the auxiliary airflow flow direction detection device is communicated with the output pipe of the smoke generator through the air inlet connector, and the airflow flow direction is detected by aligning the air outlet of the air outlet pipe to the detection port. Simultaneously, the air outlet pipe is screwed out by rotating the air outlet pipe, the air outlet hole is aligned to the detection port of the whole linear position, the air flow direction of the whole linear position can be detected simultaneously, and the detection and observation are more convenient.
