The basic working principle of the aluminum alloy tuyere is very simple. The setting is composed of the aluminum alloy tuyere and the smoke exhaust fire damper. It can be effectively and commonly used as the return tuyere of the ventilation and air-conditioning project with fire protection regulations. The inlet and outlet or the suction inlet are generally installed on the side of the ventilation duct or at the end of the ventilation duct and on the wall. It is used as a tuyere at ordinary times. The position of the exhaust cyclone can be adjusted to ensure that it is a positive pressure exhaust and that the air flow is transported as required. , Instead of being cached in an instant.

1. The pneumatic device is mainly composed of cylinders, pistons, gear shafts, end covers, seals, screws, etc.; the complete set of pneumatic devices should also include opening indications, stroke limits, solenoid valves, positioners, pneumatic components, manual mechanisms, and signals Feedback and other components.

2. The connection size of the pneumatic device and the valve should meet the requirements of ISO5211, GB/T12222 and GB/T12223.

3. The pneumatic device with manual mechanism should be able to use its manual mechanism to open and close the pneumatic ball valve when the air source is interrupted. When facing the hand wheel, the hand wheel or handle should rotate counterclockwise to open the valve, and rotate clockwise to open and close. The valve is closed.

4. When the end of the piston rod is internally or externally threaded, there should be a wrench mouth suitable for standard wrenches.

5. The sealing ring of the piston should be easy to replace and repair.

6. ​​Pneumatic device with buffer mechanism.

7. The pneumatic device with adjustable buffer mechanism should have a mechanism for adjusting the buffer function outside the cylinder.

It is usually installed on a pipe or side wall as a side air outlet. There are two movable blades with adjustable angles. The short blades are used to adjust the spread angle of the supply air flow and can also be used to change the direction of the air flow; while adjusting the long blades can make the supply air flow attached to the ceiling or tilt down to a certain angle (when When warm air is supplied).

The outer blades or the blades of the aluminum alloy tuyere can be parallel to the long side or parallel to the short side, which can be selected according to customer requirements.
