Description
Technical field
The present invention relates to pipe joint technical field, more particularly it relates to which a kind of large diameter pipeline self sealss are held
Interface.
Background technology
With the further development of urbanization and the progressively improvement of rural residence condition, public infrastructure and family
Water supply and drainage demand is further lifted, this just be unable to do without the construction workings such as Pipe installing, maintenance.
The armored concrete interface tube of bell socket not tension, sealing performance is not high, tubing from great, corrosion resistance,
Smoothness is below HDPE (high density polyethylene (HDPE)) solid wall pipe, therefore HDPE solid wall pipes have a vast market application prospect.
In the installation of pipeline and maintenance construction work, such as in drainage pipeline non-excavating construction, there is side in many cases without foot
Enough construction spaces, therefore, can only form inclined borehole in side, then well be done in opposite side, so that in Jing Neilianjieguandao, top pull
Tube coupling, completes to be laid with.
The tube coupling length of existing heavy caliber (DN >=300mm) HDPE solid wall pipes is being installed to there is 6 meters, 9 meters, 12 meters etc.
Or during maintenance construction, the existing docking mode of pipe joint only has heat-melting butt-joint, clamp connection, electric heating melting, shrink belt connection
Deng.These pipe joint modes have the disadvantage that in municipal pipeline excavation construction, non-excavating construction：1) heat-melting butt-joint needs
Certain place space, can only could construct after the completion of docking, not be suitable for excavation construction, be not suitable for top pull in well and apply
Work；2) heat-melting butt-joint can form in-flanges, it is necessary to cut off in-flanges；3) water occasion is dangerous having for electric melting connection, inconvenience
In construction；4) electric melting connection easily collapses pipe in welding, produces leak source；5) shrink belt bonding strength is lower slightly, large-diameter pipe
Road heating is uneven, it has not been convenient to；6) clamp connection is not suitable for non-excavating construction；7) pipeline connection integrity is not strong, leakproofness
Can be poor；8) pipe joint easily disconnects, and the ability for bearing pulling force and vibrations is limited.
In addition, in the market also has two kinds of HDPE pipe joint modes, i.e. rubber ring bell socket.The HDPE of bell socket is real
Wall short tube section is to cut out bellmouth at one end, and one end cuts out socket, passes through seal with elastometic washer sealing, the HDPE of rubber ring bell socket
The seal of solid wall short tube section is not strong, does not possess anti-pulling ability, although can be used for non-excavation rehabilitation, easily disconnects, no
It can be used to draw top construction.
In municipal drainage pipeline non-excavating construction, non-excavation rehabilitation, it is also desirable to a kind of to be connected in small space
It is easy to connect, airtight performance is good, stretch-proof easy interface HDPE solid wall pipe tube couplings, it is convenient in inspection shaft or active well under
Manage, inside the original pipeline of jacking, realize and replace, but the pipeline of above existing interface mode is inapplicable.

PE is managed or the pipeline of other similar materials.Its material has certain elastic deformability, with meet subsequently with pipeline self sealss
The assembling demand of the bellmouth structure of bell socket.
Socket inner wall 203 is not processed further, generally remains structural integrity, (such as outer end face is horizontal consistent for size uniform
Property is preferable) etc. basic demand can, so as to meet the subsequently assembling demand with the bellmouth structure of pipeline self-sealing socket interface.
Receptacle wall 202 is divided to for two parts, and wherein Part I is the common tube for leaving 205 specific range of socket end face
The outside of body；Part II is the interface section of specific range of extending internally from socket end face 205, the outer wall 2041 of interface section
It is integrally conical, the taper is small in socket end face, and root is big.Interface section may include one or more second class annular projections
204。
Second class annular projection 204 is located at the outside of socket tube body 201, is connected with receptacle wall 202 and (is based on outer wall 202
It is process), the second class annular projection 204 is generally also ring-type, can also equally be processed into several sections of discrete circular arcs (in figure not
Show).Second class annular projection 204 may include positioned at the first face 2041 being connected with socket tube body 201；From the first face 2041 to
The exterior extension of tube body 201 and second face 2042 vertical with 201 axes O O ' of socket tube body, first side in the second face 2042 and
First face 2041 is connected, and second side in the second face 2042 is the top of the second class annular projection 204；And with the second face 2042 and
The 3rd connected face 2043 of first face 2041.First side in the 3rd face 2043 is connected with 2042 outer end of the second face, the 3rd face 2043
The second side be connected with the first face 2041, and this second at opposite first closer to socket end face 205.Second class annular projection
204 are cut out by the external side of jack tube with rotary cutter, and quantity is more than or equal to 1.
More specifically, as shown in Fig. 2 upper left sides, in the section along axes O O ', the first of the second class annular protrusion 204
The intersection of face 2041 and section and 201 axes O O ' angulations of socket tube body are α '；The second of second class annular protrusion 204
Face 2042 and 101 axes O O ' of interface tube body are substantially vertical；3rd face 2043 of the second class annular protrusion 204 and the intersection of section
Be β ' with 101 axes O O ' angulations of interface tube body, angle [alpha] ', β ' be acute angle, and β ' ＞ α '.Angle [alpha] ' and institute above
The α stated is of substantially equal；Angle beta ' it is of substantially equal with β described above.But protection scope of the present invention not limited to this, in this hair
In bright other embodiments, the second face 2042 can not be vertical with axes O O ', but into other specific angles.
In addition, as shown in Fig. 2 upper rights, meet following requirement, i.e. wall at interface outer end face in the pipe thickness of interface
Thickness is d ', and the wall thickness at bellmouth inner face is D ', wherein D ' ＞ d ', and d is not less than 3mm.
Fig. 3 shows that a kind of section of pipeline self-sealing socket interface structure 300 according to an embodiment of the invention shows
It is intended to.As shown in figure 3, the socket shown in the bellmouth structure and Fig. 2 of pipeline self-sealing socket interface structure 300 as shown in Figure 1
Standard forms, and further comprises bellmouth tube body 101, socket tube body 201 and bell and spigot 301.
For 301 specific schematic diagram of bell and spigot shown on the right side of Fig. 3, it is to be inserted into bellmouth knot along diagram F directions by outlet structure
In structure, after extruding, the second class annular protrusion 204 of outlet structure first kind annular protrusion 104 with bellmouth structure successively
Form screens installation.The first kind annular projection 104 of bellmouth tube body 101 and the second class annular projection 204 of socket tube body 201
Geomery is complementary.Therefore, after bellmouth tube body 101 completes assembling with socket tube body 201, first kind annular projection 104 and second
Class annular projection 204 fits like a glove to form self sealss.
With reference to Fig. 1 to Fig. 3 with the 104 and second class annular projection 204 of first kind annular projection of section shape position triangle
Embodiment invention has been described, but it should be appreciated by one skilled in art that protection scope of the present invention not
It is limited to this, the protrusion of bellmouth tube body and socket tube body can also be other shapes.Fig. 4 to Fig. 7 shows first kind annular projection
