The joint of the connecting pipeline comprises a male joint and a female joint, and the male joint and the female joint of the joint are respectively arranged on two parts of the system.
The male joint and the female joint of the current quick-change joint are both provided with a stop valve function. When the pipeline is separated, the pipeline is automatically closed, so that the liquid is prevented from flowing out; when the two pipelines are combined, the pipelines are communicated, and the liquid in the pipelines circulates circularly. The liquid has a certain pressure drop in the process of pipeline circulation, and the pressure drop is larger as the flow is larger in the same pipeline environment. There must also be a certain pressure drop in the quick-change coupling system.
The existing quick-change connector is relatively small in external dimension, small in sectional area of a pipeline, poor in circulation capacity and high in pressure drop due to functional requirements and limitation of overall dimension. 2. The valve core of the stop valve in the quick-change connector is generally hooped by a sealing ring to realize tightness. When the products are combined, the valve core is separated from the outer wall to form a circulation channel, and at the moment, the inner side of the sealing ring is tightly fastened with the valve core, and the outer side of the sealing ring is not supported. Under the impact of larger water flow pressure, the sealing ring is very easy to fall off, so that when a product is separated, the function of the stop valve is invalid, and serious consequences such as leakage are caused.
