Specific embodiment
To keep technical solution of the present invention and advantage clearer, the present invention is made below with reference to attached drawing further detailed
Explanation.
As shown in Figure 1, a kind of pipeline quick union, including in adapter coupling 1 and one end insertion adapter coupling 1 and with turn
The Petrochemical Pipe Joints 2 that connector 1 is rotatablely connected.The pipeline that one end of Petrochemical Pipe Joints 2 is provided with connecting pipe connects end 22, another
End is provided with the switching being rotatablely connected in insertion adapter coupling 1 and with adapter coupling 1 and connects end 21；Correspondingly, adapter coupling 1 is arranged
The threaded ends 12 for having the inscribed end 11 for connecting with Petrochemical Pipe Joints 2 and being connect with pipeline thread, threaded ends
12 match connection with corresponding pipeline internal screw thread by the way that the external screw thread 121 of periphery is arranged in, and then in the fixed corresponding pipe of installation
Road and when threaded ends 12, adapter coupling 1 with Petrochemical Pipe Joints 2 is rotatablely connected i.e. by rotation may make corresponding pipeline and
The external screw thread 121 of 12 periphery of threaded ends matches connection, significantly reduces the difficulty of installation fixed -piping, lift line connection
Efficiency.
As shown in Figure 2 and Figure 3, it is inscribed and is provided with inner groove 115 in end 11 and is provided in inner groove 115 for rotating
The snap ring 4 at end 21 is connect, and then after switching connects end 21 in insertion adapter coupling 1, is arranged in adapter coupling 1
Snap ring 4 connects end 21 with switching and matches connection, that is, can reach the purpose of connection adapter coupling 1 and Petrochemical Pipe Joints 2, so that the structure
Simple pipeline quick union plays the role of effective lift line joint efficiency in piping connection, and to connect
There is the connection difficulty with significant decrease pipeline after the rotation connection of adapter coupling 1 at end 21, may make phase by rotation adapter coupling 1
The pipeline answered is threadedly coupled with adapter coupling 1.41 Hes it should be noted that the connection that snap ring 4 includes multiple alternately connections is drawn money on credit
The broken ends of fractured bone 43 for connecting short branch 42 and drawing money on credit between 41 positioned at two corresponding connections.And connect short branch 42 and inner groove 115
Cell wall abuts, and draw money on credit 41 intermediate position of connection is pierced by out of inner groove 115.It connects end 21 and is provided with confession from inner groove 115
The connection being inside pierced by draw money on credit 41 insertions annular groove 214 and positioned at the wild card inclined-plane 213 of 214 front end of annular groove, multiple connections
41 inscribed circle diameter of drawing money on credit is greater than the point diameter on wild card inclined-plane 213, and then connect connecing adapter coupling 1 in succession fastly with pipeline
When first 2, enable Petrochemical Pipe Joints 2 be provided with connect end 21 one end insertion be internally provided in the adapter coupling 1 of snap ring 4, move
The front end for connecing the wild card inclined-plane 213 on end 21 in dynamic continues to move to after passing through snap ring 4, so that on snap ring 4
Connection is drawn money on credit 41 to abut with wild card inclined-plane 213, since snap ring 4 is provided with the broken ends of fractured bone 43, and then connects in switching and holds 21 to be constantly inserted into
When in adapter coupling 1, the connection by 213 extruding force of wild card inclined-plane, which is drawn money on credit, 41 to be transferred to extruding force in the short branch 42 of connection, and
It draws money on credit in connection and 41 when moving on wild card inclined-plane 213 to connect short 42 deformation of branch, and the length of the broken ends of fractured bone 43 is short with connecting
It props up 42 deformation and reduces；Connection draw money on credit 41 be moved to annular groove 214 when, connect the deformation generated in short branch 42 by deformation
Restoring force will promote connection to draw money on credit 41 reply original states and be inserted into annular groove 214, be connected and fixed adapter coupling 1 to reach
With the purpose of Petrochemical Pipe Joints 2, structure is simple and easy to implement, significantly reduces the difficulty of installation fixed -piping, is obviously improved pipe
The joint efficiency on road.
It should be noted that in order to promote the physical properties such as the stress and deformation and the restoring force that connect short branch 42, and then will be even
It connects short branch 42 and is arranged to arcuation, and multiple short branch 42 of connection are arranged concentrically, and then in adapter coupling 1 relative to Petrochemical Pipe Joints 2
When rotation, it will achieve the purpose that effectively reduce the frictional dissipation connected between short branch 42 and the cell wall of inner groove 115 simultaneously, extend
The service life of snap ring 4 and adapter coupling 1.At the same time, connection is drawn money on credit and 41 is set as the cylindric of the linear property in axle center, risen
To promoted connection draw money on credit 41 structural strength effect, and effectively avoid connection draw money on credit 41 influenced because of deformation adapter coupling 1 with
Petrochemical Pipe Joints 2 are stably connected with.
As shown in Figure 1 and Figure 2, it is provided in inscribed end 11 for connecing 21 insertion of end and matched sealing slot 113.
It is provided with and the matched interior card inclined-plane 114 in wild card inclined-plane 213 in sealing slot 113 far from the side of threaded ends 12.Pass through
The matching on interior card inclined-plane 114 and wild card inclined-plane 213 will play the connective stability that promotes adapter coupling 1 and Petrochemical Pipe Joints 2 with
And the effect of leakproofness.It should be noted that the periphery for connecing end 21 is arranged, there are two seal grooves 212, and corresponding close
It is provided in sealing groove 212 with the sealing ring 3 connect in 21 insertion sealing slot 113 of end, and then connect 21 setting of end in switching
The connection of effective sealing adaptor connector 1 and Petrochemical Pipe Joints 2 is played after having in the partial insertion sealing slot 113 of sealing ring 3
The effect at place；At the same time, by the way that sealing ring 3 to be mounted in seal groove 212, end will be connect relative to switching in adapter coupling 1
21 rotation when, reach avoid sealing ring 3 from connect end 21 on be detached from and influence adapter coupling 1 and connect hold 21 between
The purpose of connection sealing energy.
The 21 abutting bottom surfaces 112 that abut are held with connecing as shown in Fig. 2, being provided in sealing slot 113, and are being abutted
Bottom surface 112 is provided centrally with water conservancy diversion inclined-plane 111.Water conservancy diversion inclined-plane 111 plays the role of promoting substance flow stability, and abuts
Bottom surface 112 will play the role of limitation and connect depth in the inscribed end 11 of 21 insertion of end, and reaches effective and promote adapter coupling 1
With the purpose of the connective stability of Petrochemical Pipe Joints 2.The front end for connecing end 21 is provided with guiding incline 211, passes through guiding incline
211 guidance, which connect the end inscribed end 11 of 21 insertion, will further decrease the difficulty connect in the inscribed end 11 of 21 insertion of end, thus
It is obviously improved the efficiency of pipeline connection.
The above description is only a preferred embodiment of the present invention, and protection scope of the present invention is not limited only to above-mentioned implementation
Example, as long as the technical solution belonged under thinking of the present invention all belongs to the scope of protection of the present invention.It should be pointed out that being led for this technology
For the those of ordinary skill in domain, several modifications and retouching without departing from the principles of the present invention, these are modified and retouching
Also it should be regarded as protection scope of the present invention.
