Abstract
The invention discloses a low-resistance tubular automatic sealing device. The low-resistance tubular automatic sealing device comprises an upper opening part and a lower opening part. The upper opening part has a circular pipe shape. The lower opening part is a concave semicircle-shaped pipe. A lower opening of the lower opening part has a gap structure. The upper opening part and the lower opening part are connected by a connection part. The low-resistance tubular automatic sealing device is prepared from an elastic material. A liquid flows into the low-resistance tubular automatic sealing device from the upper opening part. When the liquid flows through the lower opening part, the wall of the concave semicircle-shaped pipe automatically expands, and an expanding amount can be adjusted automatically according to a flow. After the liquid flows through the lower opening part, the wall of the concave semicircle-shaped pipe automatically recovers the original sealing state. The low-resistance tubular automatic sealing device realizes one-way flowing of a liquid under the condition of the minimum water head loss, automatically prevents a downstream liquid from flowing upward, and automatically prevents upward diffusion of downstream germs and injurious insects.
