Abstract
The utility model discloses a water pipe without back flow and belongs to water heating pipe fittings. The water pipe without back flow comprises a water pipe body. A retaining piece is arranged in the water pipe body, and the retaining piece is round. The diameter of the retaining piece is equal to the inner diameter of the water pipe body, and the retaining piece is connected with the water pipe body through a hinge. One side of the retaining piece is closely attached to the retaining piece and provided with a retaining ring. The outer diameter of the retaining ring is equal to the inner diameter of the water pipe body. One side, contacted with the retaining piece, of the retaining ring is provided with a round sealing ring. The retaining piece designed in the water pipe without back flow only enables water flow to pass in one way, the water flow can be prevented from back flow, and the water pipe without back flow can be conveniently used when people pump water.
Description
Technical field
The utility model relates to a kind of water pipe, specifically a kind of water pipe that does not flow backwards.
Background technique
When we used water pump to draw water, exhausting water needed timely water pipe to be taken out, otherwise after water pump stopped, the water in the bucket can flow backwards in the Hui Jing, and the work that let us draws water is wasted, and influences our water.
The model utility content
The purpose of this utility model is to provide a kind of water pipe that does not flow backwards, and this water pipe that does not flow backwards can effectively be prevented the aqueous reflux in the water stopping tube.
The technical scheme in the invention for solving the technical problem is: a kind of water pipe that does not flow backwards, comprise the water pipe body, in the described water pipe body catch is installed, catch is circular, the diameter of catch and water pipe body internal diameter etc. are big, and catch links to each other with the water pipe body by hinge, is close to catch in a side of catch to be provided with baffle ring, the external diameter of baffle ring and water pipe body internal diameter etc. are big, and the side that baffle ring contacts with catch is provided with circular seal ring.
The beneficial effects of the utility model are: current are unidirectional to be passed through the catch of the water pipe indoor design of the water pipe that this does not flow backwards to allow only, can avoid current to flow backwards, and uses when making things convenient for us to draw water.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 water pipe body, 2 hinges, 3 catch, 4 baffle rings, 5 seal rings.
Embodiment
As shown in Figure 1.A kind of water pipe that does not flow backwards, comprise water pipe body 1, in the described water pipe body 1 catch 3 is installed, catch 3 is circular, the diameter of catch 3 and water pipe body 1 internal diameter etc. are big, catch 3 links to each other with water pipe body 1 by hinge 2, be close to catch 3 in a side of catch 3 and be provided with baffle ring 4, baffle ring 4 can stop catch 3 reverse activity, play the purpose that stops that current flow backwards, the external diameter of baffle ring 4 and water pipe body 1 internal diameter etc. are big, and the side that baffle ring 4 contacts with catch 3 is provided with circular seal ring 5, and seal ring 5 can be strengthened the seal action of catch 3.
When flow, current can be pushed catch 3 open and continue to flow forward, when current flow backwards, also can promote catch 3, because the effect of baffle ring 4, current can't be pushed catch 3 open, therefore can avoid the refluence of current.Current are unidirectional to be passed through the catch 3 of the water pipe indoor design that this does not flow backwards to allow only, can avoid current to flow backwards, and uses when making things convenient for us to draw water.
