A new type of non-drip dry hose joint assembly

Abstract

The invention relates to a novel leakage-free dry type hose connector assembly. In China, a traditional design manner is basically adopted in an existing hose connector, an automatic interlocking mechanism does not exist, a coupler and an adapter often cannot be closed when the connector is cut off, accidental leakage of liquid materials is caused, the phenomenon can be frequently seen in a gas station, and gasoline or diesel oil leaks from a connection sleeve of a fuel filling hose. The novel leaking-free dry type hose connector assembly comprises a female connector and a male connector. A plurality of protruding copper sleeves are arranged on the inner wall of the lower portion of the female connector, an inwards-concave clamping groove is annually formed in the outer wall of the upper edge of the male connector, notches matched with the copper sleeves in terms of amount and size are formed in the upper wall of the clamping groove, and the female connector and the male connector are mutually connected through the copper sleeves and the clamping groove. According to the novel leaking-free dry type hose connector assembly, leaking of liquid in conveying is reduced to the maximum, and in addition, a safety guarantee is provided for operators and the environment. The novel leaking-free dry type hose connector assembly is widely applied to dripping-free and leaking-free conveying of liquid of industries of petrifaction, medicine, food and the like.

Description

technical field [0001] The invention relates to a quick connector, in particular to a novel non-drip dry hose connector assembly. Background technique [0002] At present, it is a big problem to realize dry quick connection and separation in hose fluid material transportation. The commonly used connection methods are flange connection, thread connection, socket connection and groove head connection. Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, then place the flange pad in the middle of the two flange plates, and then use bolts to fasten them together to form a tight connection. . This connection method has the advantages of high bonding strength, good sealing of the bonding surface, easy processing, and easy disassembly. However, the angle deviation cannot be adjusted by using the flange connection, and it cannot adapt to changes in the connection site conditions. Flange connections are mainly used for the connection of flange...

Problems solved by technology

[0003] At present, the existing domestic hose joints basically adopt the traditional design method, without automatic interlocking mechanism, and often cannot close the coupler and adapter when the joint is disconnected, resulting in accidental leakage of fluid materials. This phenomenon is common in gas stations. It is not uncommon to see petrol or diesel leaking from the nipple of the refueling hose
