Description

Technical Field

[0001] The utility model relates to a sampling and pressurizing device. Background Art

[0002] Drinking water purification equipment is widely used in rural areas, water plants, or remote mountainous areas and villages, and plays a key role in solving the problem of drinking water safety in rural my country. In order to improve the safety of drinking water, it is usually necessary to monitor the raw water and the purified new water. The traditional monitoring method is to manually take samples on site and then bring the samples back to the laboratory for testing. This is not only inconvenient to operate, but also has low monitoring efficiency. Usually, the purified new water is transported to the clean water tank through the water injection pipe for collection. The laboratory is generally a certain distance away from the clean water tank. If it is directly transported in the form of a branch pipe, the pressure is insufficient to complete the transportation. If it is transported through a water pump, there is a risk of dry pumping, which causes equipment damage and increases costs. Therefore, a sampling booster device is needed. Utility Model Content
