Abstract

The invention relates to a connecting device which can be quickly removed and installed, and particularly relates to a novel male plug for a quick connector. The novel male plug for the quick connector comprises a plug, wherein the inner wall of the plug extends inwards so as to form a blocking opening, a plug bushing is arranged at the blocking opening, a plug valve rod sleeves the interior of the plug bushing, the back part of the plug valve rod sleeves a plug valve seat, a plug valve core valve sleeve sleeves the interior of the front end of the plug valve rod, a plug valve core inner ring rod sleeves the interior of the plug valve core valve sleeve, a plug valve core spring is arranged between the plug valve core inner ring rod and the plug valve seat, the outer wall of the front end of the plug is sunken so as to form a spiral groove, a flow channel hole is formed in the middle inner wall of the front surface of a connector body of the plug, two horizontal installation openings are formed in the back surface of the connector body of the plug, and the back part of the plug valve seat makes contact with the inner wall of the front end of the flow channel hole. The novel male plug has the beneficial effects that loop design is adopted by the two installation openings of the shell connector body, a pressure source can be operated without shutdown, the male plug is directly inserted into a female socket for connection and disconnection, self decompression can be realized, and the tolerance pressure is high.

Description

technical field [0001] The invention relates to a quick disassembly and assembly connection device, in particular to a new type of male plug for quick connectors. Background technique [0002] Quick connectors include hydraulic quick connectors and various fluid quick connectors. It is a connection device that quickly connects or disconnects pipelines and realizes quick disassembly. Because the quick connector has a two-way check function and the pipeline is disconnected without leakage, it is widely used in the fields of petroleum, metallurgy, hydropower, construction machinery, ships, and electromechanical equipment. The connection structure of the quick connector is the most important part of the quick connector. Its connection method and structure directly determine the convenience, reliability and product quality of the quick connector. The quick connector consists of a male plug and a female socket. The male plug and the female socket contain a valve structure. The or...
