Overview

The liquid sealed sampler consists of a set of plunger cylinder body, LPG liquefaction sampler, and connecting pipeline. By manually rotating the screw rod to drive the piston movement, it is easy to safely return the liquefied gas in the LPG sampler to the original storage tank. Suitable for leak free sampling of various media in petrochemical plants, especially toxic, harmful, flammable, explosive and other hazardous medium and low-pressure gas media. The collected samples have strong authenticity, high accuracy, and no residual liquid/gas emissions. Effectively prevent the harm of toxic and harmful media to operators. At the same time, it will not pollute the environment and avoid dangerous accidents that may be caused by flammable and explosive media during sampling. Compliant with the country

Product Details

Liquid sealed sampler

Our company follows the SH/T 0233-92 "Sampling Method for Liquefied Petroleum Gas" and "Safety Requirements for Sealed Sampling in Petrochemical Industry" standards, absorbs advanced foreign technology, continuously improves design and upgrades processes to meet the needs of the domestic industry, and successfully develops a sealed sampler (gas/liquid sealed sampler), which is safe, reliable, and easy to operate. To meet higher requirements and higher quality sampling.

Suitable for leak free sampling of various media in petrochemical plants, especially toxic, harmful, flammable, explosive and other hazardous medium and low-pressure gas media. The collected samples have strong authenticity, high accuracy, and no residual liquid/gas emissions. Effectively prevent the harm of toxic and harmful media to operators. At the same time, it will not pollute the environment and avoid dangerous accidents that may be caused by flammable and explosive media during sampling. Comply with national requirements for environmental protection, fire prevention, explosion prevention, and other regulations.

Closed sampling refers to the process where the sample stream sampled from the process or equipment pipeline is returned to the process pipeline or flows towards the discharge pipeline, forming a closed loop and achieving closed sampling. The entire sampling process will not expose any process media to the air, causing personal injury or environmental pollution.

Working principle and characteristics:
Gaseous or volatile liquid media are collected in a sealed manner using seamless steel cylinders. The inlet and outlet ends of the seamless steel cylinder are controlled by safe and reliable needle valves, and equipped with stainless steel quick couplings, making installation and removal of the sampling steel cylinder safe, convenient, and fast.

The non-volatile liquid medium is collected using sealed pressure resistant bottles/ordinary open bottles, with superior sealing performance. The stainless steel protective cover ensures the safety of operators.

Liquid sealed samplerOperating Procedures

1) Before sampling, ensure that all valves are in the closed state, install the sampling bottle, and ensure that the double needle is in place

Insert into the bottle;

2) Open the inlet valve of the medium and adjust the directional valve to the circulation mode. Shake the hand pump handle to circulate the material;

3) After sufficient circulation, adjust the directional valve to the sampling mode, and the sample enters the sampling bottle,

Observe the liquid level and close the inlet valve when the sampling amount is reached.

4）Blowing: Open the blowing valve and blow the residual crude benzene in the pipeline to the sampling bottle. Adjust the reversing valve to the circulation mode and continue blowing. After blowing is complete, close the blowing valve and adjust the reversing valve to the closed mode

5）Remove the sampling bottle and complete the sampling.
