Online sampler

Thread Content

Online samplers are suitable for leak-free sampling of various media in pipelines and storage tanks within petrochemical plants, especially hazardous medium- and low-pressure gas and liquid media such as those that are toxic, flammable, or explosive. The samples are of high authenticity and accuracy; there is no release of residual liquids or gases, effectively preventing harmful toxic substances from causing harm to operators. It also does not pollute the environment, avoiding potential dangerous accidents that could arise from flammable and explosive substances during sampling. It meets the requirements for environmental protection as well as fire and explosion prevention standards. At the same time, since the plunger passes through both the valve body and the connection flange, it ensures that no residual liquid (gas) is discharged during each sampling, thereby eliminating the risk of clogging.

Some toxic and hazardous liquids cannot be stored in open sample bottles. ■Connect the inlet port perpendicularly to the main sample line (by welding or flange coupling), making sure to keep the in-line sampler horizontally installed. ■Slowly rotate the online sampler handle counterclockwise until the sample flows out from the outlet ； Sampling begins when the liquid flows out from the sample outlet. ■Once sample collection is complete, immediately rotate the handle of the online sampler clockwise until the screw is fully inserted, then turn off the online sampler to prevent environmental contamination and safety accidents caused by sample leakage. Note: To meet the actual needs of our customers, the BQZX series of online samplers designed by our company can be equipped with options such as pressure gauges and pressure reducers, connection flanges, coolers, metal hoses, outlet control valves, sampling bottles, and quick couplings. Our company has extensive experience in sampling applications across industries such as petrochemicals, pharmaceuticals, and energy. Therefore, we are capable of providing users with special designs ； Such as special containers, with hazard area design to meet safety and leak-free requirements, or special requirements under American ASME and PMI standards. The entire concept of sampling is to determine the composition and quality of the medium in the process, in order to understand the condition of the product or the process, with the goal of achieving good results at a low cost ； Sampling must be safe, simple, and accurate. Ensure the safety of operators and protect the environment, making sampling simpler and easier, while also ensuring that representative samples are obtained. 【Unique Advantages of the BQZX Type High-Viscosity Online Hermetic Sampler】 The high-viscosity online hermetic sampler features a crank-operated piston valve design, and is widely used for sampling high-viscosity fluids such as residue oil, wax oil, and sulfur, as well as fluid samples containing solid particles. An optional pre-service valve is available; a steam jacket or cooler can be installed depending on the operating conditions in industry. Steam purging or nitrogen purging is an optional feature, which allows for the removal of deposits from the piston during its movement, preventing blockages and ensuring that no residues remain and that there is no obstruction. 【Application Scope】 1. Viscous fluids, fluids containing solid particles 2. Sampling from reaction tanks, pipelines, etc. 3. High-temperature processes 4. Low-pressure or negative-pressure processes, etc
