Abstract
The utility model relates to a control valve quick connector and includes a valve body, wherein a compression spring, a steel ball and a sealing member are arranged and a plug. Connection holes are mounted in the sealing member. The upper end of the steel ball is connected with the compression spring, and the lower end of the steel ball is suppressed in the connection hole on one end of the sealing member. An inner ring groove is formed on the connecting end face of the sealing member and the steel ball, and an outer ring groove is formed on the other end face of the sealing member. A ring boss is mounted on the plug, and a support pole is arranged in the plug. Due to the inner ring groove formed on the connecting end face of the sealing member and the steel ball, two layers of internal and external tube wall are formed; a steel pipe is suppressed in the connection hole on the end face of the stealing member, and sealing is achieved by making use of elastic deformation of the sealing member itself; when the plug is plugged into, the ring boss on the plug inserts in the outer ring groove, and the steel ball is jacked-up by the support pole in the plug and is separated from the connection hole of the stealing member, thereby the whole process of sealing is completed by elastic deformation of the inner layer thin-walled tube on the upper end of the stealing member to achieve the goal of rapid breakout without leakage.
Description
Technical field
The utility model relates to a kind of joint, relates in particular to a kind of modulating valve rapid pipe joint.
Background technique
The key technology of modulating valve rapid pipe joint is sealability, when docking with plug, good sealing be arranged, and avoids tube fluid to leak, when pulling the plug out of the socket simultaneously, and can rapid down interface.The modulating valve quick coupling structure comprises Compress Spring, steel ball at present, and steel ball seat, steel ball seat are connected on the sealing seat, also are provided with elastic packing in sealing seat and the steel ball seat connecting end; Gapped and dead angle between said structure steel ball seat and the elastic packing, when plug is extracted, just having tail washings remains in the gap, the hardening of condensing in residual place, when inserting plug, the liquid that condenses and metal granule will push elastic packing, cause wearing and tearing and the distortion of elastic packing, failure condition statistics from production and application, basically all joint leakage failures are all owing to elastic packing wearing and tearing, distortion etc. cause, and working life is very short, and mean lifetime is 1 month, causes cost of production to increase.
The model utility content
The utility model purpose is that a kind of reduction user cost is provided in order to overcome the deficiencies in the prior art, improves the modulating valve rapid pipe joint in its working life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of modulating valve rapid pipe joint, comprise valve body, plug, and be provided with Compress Spring, steel ball and Sealing in the described valve body; Be provided with attachment hole in the described Sealing; Described steel ball upper end is connected with Compress Spring, and the steel ball lower end is compressed on the attachment hole of Sealing one end, and described Sealing and steel ball connecting end surface are provided with interior circular groove; Described Sealing other end is provided with outer annular groove; Described plug is provided with annular boss; Be provided with fore-set in the described plug; During connection, described annular boss is arranged in the outer annular groove; Described fore-set breaks away from the Sealing attachment hole with the steel ball jack-up that makes progress.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of modulating valve rapid pipe joint of the utility model scheme by being provided with interior circular groove at Sealing and steel ball connecting end surface, forms inside and outside two-layer tube wall; Steel pipe is compressed on Sealing end face connection hole, utilize the resiliently deformable of Sealing self to form sealing, when plug inserts, annular boss on the plug is plugged in the outer annular groove of Sealing other end, and fore-set breaks away from the Sealing attachment hole with steel ball jack-up in the plug, the sealing of whole process all is to finish by the resiliently deformable of Sealing upper end internal layer thin walled tube self, reach quick disconnecting and do not have leakage phenomenon, improved sealability, long service life.

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is not linkage structure schematic representation of a kind of modulating valve rapid pipe joint of the present utility model;
Accompanying drawing 2 is a kind of modulating valve connecting structure for quick coupling schematic representation of the present utility model;
Wherein: 1, valve body; 2, plug; 3, Compress Spring; 4, steel ball; 5, Sealing; 6, attachment hole; 7, interior circular groove; 8, outer annular groove; 9, annular boss; 10, fore-set.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1,2 is a kind of modulating valve rapid pipe joint described in the utility model, comprises valve body 1, plug 2, is provided with Compress Spring 3, steel ball 4 and Sealing 5 in the described valve body 1; Be provided with attachment hole 6 in the described Sealing 5; Described steel ball 4 upper ends are connected with Compress Spring 3, and steel ball 4 lower ends are compressed on the attachment hole 6 of Sealing 5 one ends, and described Sealing 5 is provided with interior circular groove 7 with steel ball 4 connecting end surfaces; Described Sealing 5 other ends are provided with outer annular groove 8; Described plug 2 is provided with annular boss 9; Be provided with fore-set 10 in the described plug 2; During connection, described annular boss 9 is arranged in the outer annular groove 8; Described fore-set 10 breaks away from the attachment hole 6 of Sealing 5 with steel ball 4 jack-up upwards.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
