Technical Description of Tank Top Sampling Device

1. Equipment Overview

The tank top sampling device is used to extract samples from high-level containers (such as storage tanks), usually achieved through manual control for precise sampling. This device is suitable for industrial processes that require environmental protection requirements.

2. Working principle

Apply slight pressure: Before opening the vent valve, the equipment applies a small pressure load to the container to prevent it from being damaged by impact.

Open the exhaust valve: manually or electrically operate to remove air or liquid from the system, creating conditions for sample injection.

Material feeding sample chamber: Introduce the material to be sampled into the sample chamber controlled by a floating ball. The floating ball achieves precise injection by adjusting the injection volume and position.

Floating ball floating: The floating ball automatically rises or falls under the action of liquid level or other signals, ensuring the stability of sample injection.

Close the lower valve: After sampling is completed, close the drain valve to prevent liquid leakage.

3. Sample injection process

Apply slight pressure to the container to prevent impact during sample injection,

Open the vent valve: Drain the air or liquid from the system to create conditions for sample injection.

Material Enters Sample Chamber: The material to be sampled enters the sample chamber controlled by the float.

Float up: Adjust the injection amount and position through the float device to ensure accurate injection of the sample.

Close the lower valve: After sampling is completed, close the drain valve to prevent liquid leakage.

4. The sample enters the sampling bottle

Connect to the output end of the tank top sampling device through a pipeline to directly receive samples.

Adjust the injection volume of the float according to sampling requirements (such as volume, concentration, etc.).

5. Precautions

Ensure that there is no liquid residue at the bottom of the container, otherwise it will affect the positioning and injection effect of the float.

Regularly check the sealing and connection of the floating ball device to prevent leakage.

Avoid overloading or overpressure during operation to ensure safe operation of the equipment

6. Safety requirements

The top sampling device of the tank should comply with relevant environmental and safety standards (such as ISO, GB, etc.)

Operators need to wear appropriate protective equipment (such as gloves, goggles, etc.).

Prevent liquid leakage to unexpected areas and avoid injury to operators.

7. Maintenance and upkeep

Regularly check the sealing and pressure test. Clean the residual liquid at the bottom of the container.

Adjusting according to the usage of the equipment can ensure the high accuracy and reliability of the tank top sampling device. This device is suitable for various industrial scenarios, including sample collection needs in industries such as petroleum, chemical and pharmaceutical.
