Pipeline needle core sampling valve series - press type

Pipeline needle core sampling valve is a device used for online sampling, widely used in industries such as chemical, petrochemical, pharmaceutical, and hazardous chemicals. This valve has a blowdown function that can remove residues during the sampling process, ensuring sampling accuracy and safety.

1. Main features

Online sampling:

Sampling can be carried out directly on the running pipeline without stopping the machine.

Equipped with blowing function: By blowing, residual substances inside the sampling valve can be removed to avoid cross contamination.

Puncture type design: suitable for various types of pipelines, able to penetrate the sampling bottle stopper for sealed sampling, ensuring sample quality.

2. Multiple configuration methods:

Press reset: easy to operate, suitable for frequent sampling occasions,

Handwheel switch: The valve is controlled by the handwheel for stable and reliable operation.

Handwheel reset: Handwheel reset design facilitates valve reset operation.

Lineable: The valve can be lined with corrosion-resistant materials inside, suitable for corrosive media

Specification range: DN15-DN200, suitable for pipes of different diameters.

Temperature range: It can withstand a maximum working temperature of 200 ° C.

Limit design: The valve has a limit function to ensure accurate switch position and avoid excessive operation.

3. Application industry

Chemical industry: used for online sampling of various chemical media.

Petrochemical: Suitable for sampling high-temperature and high-pressure media in the petrochemical industry.

Pharmaceutical: Meets the high cleanliness requirements of the pharmaceutical industry, ensuring that sampling is free of contamination.

Hazardous chemicals: Suitable for sampling hazardous chemicals to ensure operational safety.

4. Operating instructions

Press reset:

Press the valve handle to perform sampling operation. After sampling is completed, release the handle and the valve will automatically reset.

Handwheel switch: The valve is controlled by rotating the handwheel, and after sampling is completed, the handwheel is rotated in reverse to close the valve.

Handwheel reset: After sampling is completed, reset the valve to its initial position using the handwheel.

5. Maintenance and upkeep

Regularly check the sealing performance of the valve to ensure no leakage.

For corrosive media, regularly check the integrity of the lining material and replace it if necessary. Keep the valve clean to prevent impurities from entering and affecting sampling accuracy.

6. Safety precautions

Before operation, ensure that the pressure inside the pipeline has been reduced to a safe range.

Wear appropriate protective equipment during sampling to avoid direct contact with harmful media

Regularly conduct functional checks on valves to ensure their proper functioning.

Summary:

Pipeline needle core sampling valve is an efficient and safe online sampling device suitable for various industrial applications. It is designed with a blowing function and multiple operation modes to ensure the accuracy of sampling and the convenience of operation. Widely used in industries such as chemical, petrochemical, pharmaceutical, and hazardous chemicals, it is an indispensable and important equipment in industrial production.
