Anti-overflowing pipe

Abstract

The invention belongs to the technical field of fluid parts, and particularly relates to an anti-overflowing pipe. The anti-overflowing pipe comprises a pipe wall and a valve. The section of the innerside wall of the pipe wall on the plane which is perpendicular to the length direction of the pipe wall is oval, and the section of the outer side wall of the pipe wall on the plane which is perpendicular to the length direction of the pipe wall is in a sealed ring shape. In the plane where the long oval axis of the inner side wall and the length direction of the pipe wall are located, the section of the valve is of a V-shaped structure, the valve is connected with the inner side wall, and a cut seam is formed in the valve and used for guiding the fluid to flow in the single direction. According to the anti-overflowing pipe, the valve which is of a V-shaped structure is arranged on the pipe wall with the oval section, and therefore the fluid can be sucked out under the action of the suction force, the phenomena that the fluid is wasted, and a user is scalded and wetted are avoided, and the personal safety of the user can be guaranteed. Meanwhile, the valve can have a buffer effect onthe circulation of the fluid, the hidden danger of the situation that the fluid flows too rapidly is avoided, and the phenomenon that due to the fact that the fluid located outside the pipe wall passes through the valve and flows into the pipe wall, the fluid pollution happens can also be avoided.

Description

technical field [0001] The invention belongs to the technical field of fluid fittings, in particular, the invention relates to an anti-overflow pipe. Background technique [0002] In the control of fluid flow, people hope that the flow of fluid in the pipeline conforms to people's wishes, that is, when fluid flow is required, the fluid flows in the pipeline in the specified direction; when fluid flow is not required, the fluid flows in the pipeline No overflow or reverse flow occurs, so as to avoid fluid waste and accidental injury of personnel. [0003] At present, most of the straws in daily life are not equipped with a structure for controlling the flow of fluid, but a simple cavity. When used with a cup, after the cup is pressurized or due to the heat and cold contraction of the fluid, the fluid will easily overflow along the straw, causing Waste of resources. Moreover, if the temperature of the fluid is high, quick contact with the human body is likely to cause burns,...

[0003] At present, most of the straws in daily life are not equipped with a structure for controlling the flow of fluid, but a simple cavity. When used with a cup, after the cup is pressurized or due to the heat and cold contraction of the fluid, the fluid will easily overflow along the straw, causing waste of resources

Moreover, if the temperature of the fluid is high, it is easy to cause burns if it touches the human body quickly, and the existing straw does not have a structure to slow down the flow of the fluid, so there are hidden dangers in use
