The utility model relates to a double-surface hot melting socket joint used for connecting composite pipes in water supply and sewerage systems, gas supply systems, chemical industry systems, thermal power systems, etc. The joint is provided with a socket opening between an inner annular wall and an outer annular wall at least on one end, and the inner side of the inner annular wall is provided with a lining. The utility model is characterized in that the socket opening also comprises a socket balancing groove. When the utility model is welded with composite pipes, air in the socket opening can be expelled through the socket balancing groove. The utility model avoids the formation of sealing air cavities, reduces socket resistance, avoids the formation of bubbles on welding positions, ensures the welding effect, the structure of the socket balancing groove is hidden beneficial to ensure the integrity of the socket joint and the utility model can ensure that the lining can be placed on a proper place after composite pipes are welded.
Description
Technical field
The utility model relates to the new-type permanent connection moulding pipe fitting that a kind of substituted metal and plastic composite pipe screw thread FERRULETYPE commonly used such as is connected at the type pipe connector, and a kind of specifically hot melt that can be used for systems such as plumbing, air feed, chemical industry, heating power is accepted pipe fitting.
Background technique
The Placement of existing metal and plastic composite pipe normally realizes by screw thread FERRULETYPE link (joint), is that the utility model patent of CN2410515Y and CN2563397Y promptly discloses this linkage structure as notification number.But manufacture cost height, join strength and the poor reliability of this piecing devices, seal ring is easily aging behind the use certain hour, causes leaking.Notification number is that the utility model patent of CN2644848Y has proposed the technological scheme of a kind of " thermofusible spigot pipe fitting " at the defective of above-mentioned two schemes, but still there is following shortcoming in the latter:
During 1, with the composite pipe welding, birdsmouth becomes the cavity of sealing because of the shutoff of composite pipe, be sealed with air in it, and it is dark more that composite pipe inserts birdsmouth, the air pressure of sealing is big more, rebounding force to composite pipe is big more, the composite pipe of larger caliber especially, and the area of contact of joint and composite pipe is big when adding socket joint, the resistance of socket joint is just bigger, is not easy to site operation; And, cause bubble easily in weld portion, influence the welding quality.
During 2, with the composite pipe welding, lack location, cause to be positioned at suitable position with composite pipe welding back bush to lining.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition at first be overcome socket pipe member that existing product exists when being connected with composite pipe in its birdsmouth the phenomenon of formation seal air cavity, the two-sided thermofusible spigot joint of a kind of sealability height, low cost of manufacture is provided; Next is that lining is located.For this reason, the utility model is taked following technological scheme:
A kind of two-sided thermofusible spigot joint, at least one end of described joint has the birdsmouth between inside and outside ring wall, and described internal ring wall inboard is equipped with lining, it is characterized in that described birdsmouth also includes the socket joint compensating groove.When the composite pipe that will carry out the hot melt processing is plugged in the birdsmouth, lining has supporting role to internal ring wall and composite pipe, links together thereby composite pipe and joint fused well, can not produce molten knurl therebetween, connect the precision height, and intensity is big, good seal performance; During especially with the composite pipe welding, the air in the birdsmouth can be discharged by the socket joint compensating groove, avoids the formation of seal air cavity, reduce the socket joint resistance, avoid forming bubble, guarantee the welding effect at the welding position, and socket joint compensating groove structure is hidden, is beneficial to the integrity that guarantees bell and spigot joint.
As the further of technique scheme improved and replenish, can adopt following concrete technical measures:
Described compensating groove is opened in the inboard of external annulus.To avoid compensating groove to be opened on the internal ring wall and influence sealability.
The outside of described external annulus is provided with the stiffening rib corresponding with compensating groove.Increase the intensity at this place.
There is gulde edge the outer end of described lining to the turnover of the end of internal ring wall.With the time,, guarantee to be positioned at suitable position with composite pipe welding back bush to the lining location with the composite pipe welding.
Described inside and outside ring wall is structure as a whole.
Described inside and outside ring wall is for dividing body structure.
Described lining is positioned at the degree of depth of the length of joint part greater than birdsmouth.So that have good supporting role.
The utility model passes through at the birdsmouth of the end of joint setting between inside and outside ring wall, at birdsmouth the socket joint compensating groove is set, and in internal ring wall the side lining, there is gulde edge the outer end of lining to the turnover of the end of internal ring wall, when socket joint connects, make lining that internal ring wall and composite pipe are had supporting role, link together, can not produce molten knurl therebetween thereby composite pipe and joint fused well, connect the precision height, and intensity is big, good seal performance; During especially with the composite pipe welding, the air in the birdsmouth can be discharged by the socket joint compensating groove, avoids the formation of seal air cavity, reduce the socket joint resistance, avoid forming bubble, guarantee the welding effect at the welding position, and socket joint compensating groove structure is hidden, is beneficial to the integrity that guarantees bell and spigot joint; Guarantee to be positioned at suitable position with composite pipe welding back bush.

Fig. 2 is that the A of Fig. 1 is to enlarged view.
Fig. 3 is the coupled condition schematic representation of structure shown in Figure 1.
Embodiment
As shown in Figure 1, 2, this two-sided thermofusible spigot joint is that internal ring wall 6, external annulus 5 are set in the end of one-time formed plastic joint 1, form the birdsmouth 4 comprise socket joint compensating groove 3 between the inside and outside ring wall, and at the corresponding position formation stiffening rib 2 of the outside of external annulus 5 and socket joint compensating groove 3; Interior side one stainless steel lining 7 at internal ring wall 6, the inner of this stainless steel lining 7 extends the inboard of birdsmouth 4 bottoms, be that lining is positioned at the degree of depth L2 (be L1-L2＞0) of the length L 1 of joint part greater than birdsmouth, can when connecting, socket joint play good supporting role like this to internal ring wall and composite pipe, there is gulde edge 8 its outer end to the turnover of the end of internal ring wall, with the time,, guarantee to be positioned at suitable position with composite pipe welding back bush to the lining location with the composite pipe welding.
As shown in Figure 3, when socket joint connects, hot melt is carried out in the end of joint birdsmouth 4 ends and aluminium-plastic composite pipe 9 handle, then aluminium-plastic composite pipe 9 is injected in the birdsmouths 4, the inner and outer surface that can make composite pipe 9 fuses together with the inner cylindrical surface of internal ring wall external cylindrical surface, external annulus respectively; Therebetween, air in the birdsmouth 4 can be discharged by socket joint compensating groove 3, avoid the formation of seal air cavity, reduce the socket joint resistance, avoid at welding position formation bubble, guarantee the welding effect, and the outer end of lining there is gulde edge to the turnover of the end of internal ring wall, makes to be positioned at suitable position with composite pipe welding back bush.And, forming under the prerequisite of first road sealing by the internal surface of composite pipe and internal ring wall external cylindrical surface, being opened in socket joint compensating groove on the external annulus can not influence the sealability at welding position and external annulus support and the heat seal strength to composite pipe substantially.
