Description
Technical field
The present invention relates to pipe fitting field, and in particular to a kind of snap joint.
Background technology
The Main Function of the joints such as threeway, four-way is to change flow direction.In daily life and industrial production, threeway, four
It is logical to wait joint to widely use when pipeline connects.However, being but frequently run onto such problem in actual use：One
The pipeline of Jing installations needs to be further added by a branch, needs first to block the pipeline when being connected with existing joint, then
Threeway is installed in truncated position, is needed former pipeline at least one end is carried out suitably to rotate and adjust in threeway installation process, or even is had
When other pipelines also accordingly to change, make work progress complicated, time-consuming.
The content of the invention
It is an object of the invention to provide a kind of snap joint, is divided with realizing easily and efficiently increasing on existing pipeline
The purpose on road.
In order to achieve the above object, the technical solution used in the present invention is：
A kind of snap joint, including main body；Body interior can be arranged as required to into difference in cylinder, cylindrical diameter
Specification.
The main body includes fixture block and lower fixture block；The upper fixture block is provided with guiding gutter, sealing ring and several joints；
Sealing ring is arranged at around guiding gutter, is sealed, and joint is connected with guiding gutter, fluid is respectively connect with Jing guiding gutters flow direction
Head, joint are provided with screw thread and connect for by-pass tube.
The upper fixture block and lower fixture block side are connected by articulate, and opposite side is connected by Detachable connection structure；Can
After dismounting attachment structure side is opened, main body can around hinge rotation.
Detachable connection structure includes that side sets threaded cylinder body nut, screw, pad and opening for screw activity
Mouthful；During cylinder body nut is positioned over lower fixture block and can rotate, screw is engaged with cylinder body nut, screw it is elastic, be used for
Install and dismounting punching joint.
Also include inner core, inner core is in hollow cylinder shape；The inner core includes inner core and lower inner core.The upper inner core and
Lower inner core is split to form by two tangent planes of a hollow cylinder Jing, and two tangent planes are respectively the tangent plane one of radial direction and cutting for vertical radial direction
Face two, the tangent plane one of radial direction along the straight radial direction of cylindrical end face and perpendicular to cylindrical end face, the tangent plane two of vertical radial direction from
Cylinder inwall a little starts, perpendicular to the straight radial direction of cylindrical end face and perpendicular to cylindrical end face.Adopt the structure with
Afterwards, can eliminate inner core to a certain extent and install between body with slight amplitude relative movement between upper fixture block and lower fixture block
Caliber error so as to combine more closely, guarantee that the product can reach zero seepage.
The upper inner core inwall is provided with toroidal cavity, and concentric manhole is provided with the middle of toroidal cavity, and through hole is straight
Footpath is provided with O-ring seal less than circular diameter in toroidal cavity in toroidal cavity；Toroidal cavity is used to place and fix O
Type sealing ring so as to difficult for drop-off, O-ring seal coordinate Jing extruding to seal with body.
The inner core and main body are engaged, and inner core external diameter is equal with inner major diameter, and through hole is corresponding with water conservancy diversion groove location, interior
Cylinder internal diameter can be arranged as required to into different size.
Preferably, one end of the radial section one of the upper inner core is provided with projection, one end of the radial section one of lower inner core
Correspondence position is provided with the groove being engaged with projection.Both can prevent inner core and lower inner core in axial direction after cooperating
Relative movement.
Preferably, on the sealing ring, positive and negative is equipped with a circle projection；The projection can play better seal effect
Really.
Preferably, the inner tank theca is provided with projection, and main body inner wall correspondence position is provided with the groove being engaged with projection.
After both are engaged, inner core rotationally and axially moving in main body can be prevented, simultaneously as raised and groove is correspondence
Arrange, positioning can be played a part of in installation process, prevent setup error.
Further, the upper fixture block Detachable connection structure side is provided with groove, lower fixture block with lower fixture block touching position
Correspondence position is provided with the projection with fit depressions；More accurately it is engaged fixture block and lower fixture block, will not misplaces, it is ensured that pipe
The sealing on road, zero leakage.
Further, the joint quantity can be one, two, three or more.Joint quantity can be set as needed
Put, the joint of varying number can meet the requirement that actually used middle needs separate varying number branch.
Beneficial effects of the present invention：
1. pipeline need not be blocked the branch that can just realize pipeline, it is only necessary to punch on the pipeline for want branch, so
Afterwards the product of the present invention is arranged on pipeline and is capable of achieving branch.
2. main body is individually applied in combination the installation that can match different tube diameters with the inner core for using or coordinating different size
Pipeline.
3. going up to have the relative movement of small discharge amplitude between inner core and lower inner core, can eliminate micro in installation process
Caliber error, and it is more tight that product of the invention can be made to be combined with pipeline, is not susceptible to seepage.
4. the joint of varying number can meet the requirement that actually used middle needs separate varying number branch.
