Description

TECHNICAL FIELD

[0001] The utility model relates to refrigerant technical field especially is a kind of refrigerant product sampling and analysis instrument sample introduction facility. BACKGROUND

[0002] 1-chloro-3,3,3-trifluoropropene (HFO-1233zd) is a typical product of the fourth generation of refrigerants. It has low global warming potential (GWP), zero ozone depletion potential (ODP), low toxicity, and other excellent physical and chemical properties, making it widely demanded in the market and having many typical application scenarios. Depending on the different application scenarios and customer needs, HFO-1233zd products are often packaged in various specifications, including ISO tank packaging, ton steel cylinder packaging, and small steel cylinder packaging. To ensure product quality, sampling and analysis are required for the above-mentioned different specifications of product packaging to ensure that the purity, acidity, moisture, and other indicators meet the product specification requirements.

[0003] The conventional sampling assembly of refrigerant product packaging generally consists of a sampling valve body, a sampling bottle, and a fixed process pipeline. The sampling valve body is usually installed in the process pipeline, which is usually fixed and cannot be moved. When sampling, the refrigerant production personnel usually need to first use a forklift or other tools to move the refrigerant packaging to the vicinity of the fixed process pipeline with the sampling valve body installed, then connect the refrigerant product packaging and the process pipeline through a hose or a hard pipe (usually requiring a wrench and bolt assembly during connection), and embed the sampling bottle into the sampling valve body to complete the sampling unit operation. Before sampling, the production personnel usually need to replace the residual refrigerant material in the process pipeline to ensure that the refrigerant product sample is qualified and uncontaminated. After sampling, the production personnel usually need to recover a small amount of refrigerant material in the process pipeline to reduce waste of useful products. After sampling is complete, the production personnel need to remove the hose or hard pipe connecting the refrigerant product packaging and the process pipeline, and use a forklift or other tools to move the refrigerant product packaging to a storage location. Under the existing sampling operation mode, the sampling process of a single refrigerant product packaging usually takes 15-30 minutes, which is time-consuming and tedious. There may also be sample cross-contamination between different batches and different specifications of refrigerant product packaging during the sampling process.

[0004] When the refrigerant inspector analyzes the sample, the sampling bottle needs to be fixed near the sample introduction instrument, and then the sampling bottle is connected to the instrument through a sampling needle or a conduit (usually a wrench and a nut are used during the connection) to complete the analysis sampling operation. During sampling, the inspector generally needs to replace and leak test the sampling needle or conduit to ensure that the sample sampling is not contaminated and is representative; the inspector also needs to operate and check the instrument gasket to ensure that the sampling needle or conduit can be smoothly introduced into the analysis instrument and there is no leakage. Under the existing sampling operation mode, the analysis process of a single refrigerant product sample usually takes 15-20 minutes, which is time-consuming and tedious, and there may be sample contamination, sampling needle or conduit connection leakage, and instrument gasket frequent failure during the analysis process.
