Technical Field

[0001] The utility model relates to the technical field of sealed sampling at a pump outlet, in particular to a practical sealed sampling device for a pump outlet. Background Art

[0002] The pump outlet sealed sampling device is a device specially designed to collect samples safely and accurately from the pump outlet.

[0003] In the existing pump outlet sealed sampling technology, for example, the existing technology with application number CN201921956383.4, it includes a sampling point pump, a feed pipeline, a discharge pipeline, a first valve, a second valve, a sampling pipeline, a bypass pipeline, a third valve, a three-way valve, a fourth valve and a drain. By adding a bypass and a valve to the sampling point pump outlet pipeline of the device and installing a three-way valve at the intermediate sampling point, there is no need to discharge the material during sampling.

[0004] However, some of the materials that need to be sampled are toxic or flammable and explosive. Discharging the materials directly from the existing sampling port may cause personnel to directly contact the materials and cause poisoning, or the volatilized flammable and explosive gases may form explosive gases, which may cause explosion risks, thereby reducing safety. Utility Model Content

Personnel do not directly contact the materials, there is no risk of leakage, and safety is improved.

[0006] The utility model provides a practical pump outlet sealed sampling device, comprising a main body mechanism; further comprising a bypass mechanism and a sampling mechanism, wherein the bypass mechanism is mounted on the main body mechanism, and the sampling mechanism is mounted on the bypass mechanism, and the main body mechanism and the bypass mechanism assist the sampling mechanism in sampling the pump outlet; the main body mechanism and the bypass mechanism assist the sampling mechanism in sampling the pump outlet, so that the operator does not directly contact the material, thus preventing poisoning, reducing the risk of explosion, and improving safety.

[0007] Preferably, the main mechanism includes a feed pipeline, a sampling point pump, a discharge pipeline, a first valve and a main pipeline valve. The feed pipeline is connected to the sampling point pump, and the discharge pipeline is also installed on the sampling point pump.

The first valve and the main pipeline valve can assist the bypass mechanism and the sampling mechanism to complete sampling.

[0008] Preferably, the bypass mechanism includes a bypass pipeline and a bypass valve, both ends of the bypass pipeline are installed on the discharge pipeline, both ends of the bypass pipeline are located at both ends of the main pipeline valve, and the bypass valve is installed on the bypass pipeline; when the sampling point pump is opened, the material enters the sampling point pump through the feed pipeline, and then is discharged through the discharge pipeline. At this time, the bypass valve is opened, the main pipeline valve is adjusted down, and the material completes the circulation through the bypass pipeline.

[0009] Preferably, the sampling mechanism includes a sampling valve and a sampling bottle, the sampling valve is installed on the bypass pipeline, and the sampling bottle is installed at the bottom end of the sampling valve; when the sampling point pump is turned on, the material enters the sampling point pump through the feed pipeline, and is then discharged through the discharge pipeline. At this time, the bypass valve is opened, the main pipeline valve is adjusted down, and the material completes the circulation through the bypass pipeline. The sampling valve is opened, and the material enters the sampling bottle. When the liquid level in the sampling bottle is reached, the sampling valve is closed, the main pipeline valve is adjusted up, the bypass valve is closed, and the material is transferred normally.
