Abstract
The invention discloses a fast joint component and a unidirectional sealing plug and a socket thereof; the fast joint component comprises a plug-in and adaptive first unidirectional sealing joint and a plug-in and adaptive second unidirectional sealing joint, an active valve core is arranged in a fluid channel of the housing of the first joint in elastic assembly along the shaft direction, a fixedvalve core which is mutually contacted and coordinated with the active valve core along the shaft direction is fixedly assembled in the fluid channel of the housing of the second joint, an active sea ling sleeve which is mutually contacted and coordinated with the corresponding end of the first joint housing along the shaft direction is mounted between the fixed valve core and the housing of the second joint in elastic assembly along the shaft direction, and the inner and the outer surfaces of the active sealing sleeve are separately coordinated with the fixed valve core and the corresponding surface of the housing of the second joint in sealing way to form an unidirectional valve structure. When the two joints of the invention are butt-jointed and moved in a relatively short distance, theopening action can be triggered, which is not easy to be affected by the deformation amplitude of springs; compared with the existing art, the structure that elastic components are mutually contacted is more reliable and sensitive.
Description
Technical field
The present invention relates to be used to realize infuse/air pipe is at the joint of the quick break-make of joint.
Background technique
Present some are used to infuse/rapid pipe joint of tracheae, constitute adapter assembly by two one-way sealing joints of joining mutually, and during use the butt joint of two joints just can be realized the intercommunication in two one-way sealing joint institute connecting leg roads.Like Chinese patent CN 2593017 disclosed " hydraulic bidirectional rapid pipe joint "; As shown in Figure 5, this rapid pipe joint comprises the left and right valve body of built-in nonreturn valve core, when not docking; Nonreturn valve core in two valve bodies is with the valve channel one-way sealing; During butt joint in two valve bodies left and right spool support mutually and retreat, with about two one-way valve opens, its connecting leg road is connected.But the spool in this adapter assembly is the elasticity movable part; Two spools the having relatively high expectations of elastic force proportioning of corresponding spring; After the spring of an elastic member is aging, elastic force diminishes; Elastic strain when supporting mutually just possibly mainly occur on the less spring of elasticity, and cause elastic force can't retreat than the corresponding spool of big spring or backward travel very little and intercommunication can't be accomplished or mobile unobstructed inadequately.
