Embodiment

[0012] Such as figure 1 , 2 , 3, 4, and 5 show the housing valve seat for the new quick connector, including the housing valve seat main body 29, the housing valve seat main body 29 including the annular body A46 and the annular body B47, and the annular body A46 and the annular body B47 are integrated Forming, the annular body A46 is in the front, and the outer diameter of the annular body A46 is smaller than the outer diameter of the annular body B47. The hole B45 and the through hole A44 are located in front of the through hole B45, the outer wall of the rear part of the annular body B47 protrudes outwards to form an annular body A, and the annular body A is horizontally provided with a through hole C43, and the annular body A is in contact with the slot, and The inner wall of the through hole C43 is not smaller than the inner wall of the ring body D to avoid the impact and wear of the medium. The rear end of the ring body B47 opens to form a flow channel, which extends to...

Abstract

The invention relates to a connecting device for quick detaching and mounting, in particular to a novel shell body valve seat for a quick connector. The novel shell body valve seat for the quick connector comprises a shell body valve seat main body. The shell body valve seat main body comprises an annular body A and an annular body B. A bulge is arranged at the front end of the annular body A. A through hole A and a through hole B are formed in the annular body A in a longitudinal penetrating mode. The through hole A is located in front of the through hole B. The rear outer wall of the annular body B protrudes outward to form the annular body A. A through hole C is formed in the annular body A in a horizontal penetrating mode. The rear end of the annular body B is open to form a flow channel. The novel shell body valve seat has the beneficial effects that when a male plug is not inserted, the through hole B communicates with a medium loop flow channel for returning of a medium; and when a female socket is connected with the male plug, the through hole B is shielded by a shell body lining inner ring, the through hole A is open, a working pressure flow channel is gotten through, the medium flows to the female socket through the through hole A to return to the female socket; and a gap remains between the rear portion of the shell body valve seat and a shell body valve sleeve to form the medium loop flow channel, and a pressure source can operate without shutdown.

Description

technical field [0001] The invention relates to a fast disassembly and assembly connection device, in particular to a novel casing valve seat for a quick joint. 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 ordi...
