Operation Guide: Correct usage methods and techniques for upward and downward expansion discharge valves

1、 Introduction

As a key component in the fluid control system, the correct usage and skills of the up and down expansion discharge valves are crucial for ensuring the smooth progress of the production process and extending the service life of the equipment. This article will provide a detailed introduction to the correct usage methods and techniques of the up and down expansion discharge valves, helping operators better grasp the key points of equipment use.

2、 Preparation before use

Equipment inspection: Before use, a comprehensive inspection should be carried out on the upper and lower expansion discharge valves, including the appearance, sealing performance, connection parts, etc. of the valves, to ensure that the equipment is intact and without leakage.

Cleaning equipment: Remove impurities and residues from the inside of the valve to ensure its unobstructed flow.

Installation confirmation: Confirm that the valve is correctly installed on the discharge port of the material container and is well sealed with the container.

3、 Operation method

Pneumatic operation:

Easily turn the handwheel and move the switching handle to the "division" indicator, ready for pneumatic operation.

When the air source enters the solenoid valve, the valve will automatically open or close according to the on/off state of the solenoid valve.

The red button is a switch button for manual debugging, which can be manually intervened when needed.

Manual operation:

Turn off the air source, and when there is no air source pressure, turn the handwheel to move the switching handle to the "close" indicator to perform manual operation.

Control the opening and closing of the valve by turning the handwheel counterclockwise or clockwise.

4、 Usage tips and precautions

Adjust the opening: According to the fluidity and flow requirements of the material, adjust the opening of the expansion discharge valve to achieve the ideal discharge speed and effect.

Avoid overload: During operation, ensure that the equipment runs smoothly, avoid excessive load and vibration, and avoid damage to the equipment.

Timely maintenance: Regular maintenance and upkeep of equipment, including cleaning, lubrication, and replacement of vulnerable parts, to ensure the normal operation of the equipment and extend its service life.

Safe operation: Before operation, ensure that the equipment is completely stopped and the power is turned off to prevent operators from getting caught in the equipment or being injured by accidentally touching and opening the equipment.

Media selection: Pay attention to selecting suitable media for use, and avoid using media that may cause corrosion or damage to the valve.

5、 Conclusion

By mastering the correct usage methods and skills of the up and down expansion discharge valves, operators can better control the flow of fluid and ensure the smooth progress of the production process. Meanwhile, regular maintenance and upkeep are also key to ensuring the long-term stable operation of the equipment. I hope this article can be helpful to operators and improve the efficiency and safety of equipment use.
