Problems solved by technology

[0003] The current quick connectors and valves are basically designed as telescopic plugs. The maximum cross-sectional area of ​​the plug needs to be greater than the cross-sectional area of ​​the pipe at the valve to ensure that the pipeline is blocked, so that the largest cross-sectional area of ​​the pipe at the valve is The cross-sectional area of ​​the pipe is more than twice that of the pipe to ensure the space required for the liquid to pass through, resulting in a large volume occupied by the quick connector. When flowing through this path, due to the large change in cross-sectional area, the pressure loss is also large

Embodiment Construction

[0032] The invention discloses a quick joint, which reduces the maximum cross-sectional area of ​​the quick joint and reduces the change of the cross-sectional area when the liquid passes through the quick joint, so that the pressure loss of the liquid passing through the quick joint is small.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] see Figure 1-Figure 11 , the present invention discloses a quick connector, including a plugged male connector 1 and a female connector 2, the male connector 1...

Abstract

The invention discloses a quick joint, which comprises a male joint and a female joint which are connected in an inserted mode, positioning shafts are arranged in the male joint and the female joint correspondingly, and valves are rotationally connected to the positioning shafts; and valve jacking-open structures are arranged at the positions, close to the inserted-connection ends, of the positioning shafts. The male joint and the female joint are each of an overturned-type valve structure, and under the situation of the equal maximum pipeline sectional area, the circulation cross-sectional area at the valve is increased. At the valve butting position, under the situation of the equal flow and the equal circulation cross-sectional area, the maximum sectional dimension of the quick joint isdecreased effectively, when liquid flows through the quick joint, the change of the cross-sectional area is small, and the pressure loss during liquid flowing is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a quick connector. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. [0003] The current quick connectors and valves are basically designed as telescopic plugs. The maximum cross-sectional area of ​​the plug needs to be greater than the cross-sectional area of ​​the pipe at the valve to ensure that the pipeline is blocked, so that the largest cross-sectional area of ​​the pipe at the valve is The cross-sectional area of ​​the pipe is more than twice that of the pipe to ensure the space required for the liquid to pass through, resulting in a large volume occupied by the quick connector. When flowing through this section of the path, due to the large change in cross-sectional area, the pressure loss generated is also large. [0004] Therefore, how to provide a quick connector with a small maximum cross...
