Abstract
The utility model relates to a separation type pipeline joint used for connecting an aluminum plastic composite pipe and a plastic pipe. The utility model is composed of a joint matrix, an inner sleeve pipe, a sealing ring, a pressing ring, and a nut. The separation type pipeline joint is characterized in that the joint matrix and the inner sleeve pipe are in a separated structure. The inner sleeve pipe is inserted in a cavity of the joint matrix after the rear end of the inner sleeve pipe is covered by a sealing ring. The utility model has the advantages of good sealing effect, high tensile strength, convenient installation, etc.
Description
The utility model relates to a kind of pipe coupling, and this pipe coupling is applicable to the connection of plastic tube or aluminium-plastic composite pipe.
Traditional joint that is used for the iron pipe connection, significant discomfort is used for being connected of plastic tube and aluminium-plastic composite pipe.Our company once designed and was used for the joint that plastic tube is connected with aluminium-plastic composite pipe, as the patent application technology of application number 97240285.3 and 97240355.8.It is big that these two kinds of joints have a bond strength, advantages such as good seal performance, but still remain to be improved conveniently installing.
The purpose of this utility model provides a kind of new pipe coupling, existing stronger join strength and excellent sealing performance, convenient widely again the installation.
The utility model adopts split-type structural, is made up of joint parent, inner sleeve, nut, compressing ring and seal ring.Stretch into behind the seal ring on the front end sleeve of inner sleeve by in the adapter, and taken over road appearance cover upper cap nut and packing ring; Joint parent inner chamber is stretched into after putting seal ring in the rear end of inner sleeve, nut is threaded onto on the thread of joint parent appearance again.Along with the nut precession, packing ring will be taken over road and inner sleeve and compress and seal, and also inner sleeve closely will be connected with the joint parent simultaneously.
Below by drawings and Examples the utility model is further described.
Fig. 1 and Fig. 2 are respectively a kind of exploded view and collection dress figure of embodiment;
Fig. 3 and Fig. 4 are respectively the exploded view and the collection dress figure of another embodiment.
With reference to Fig. 1 and Fig. 3, the utility model comprises joint parent (10), inner sleeve (20), packing ring (30) and nut (40); Narrow with inner cone inclined-plane (41) inboard of nut (40) one ends, and the other end passes through internal screw thread (42) rotation set in the external screw thread (11) of joint parent front end; Two ends, packing ring (30) outside are provided with outer cone inclined-plane (31,32).The utility model has also been done brand-new design: be the branch body structure between joint parent (10) and the inner sleeve (20); The outside, inner sleeve (20) rear end is provided with seal groove or half groove (21) and is with seal ring (22), or at joint parent front end inner chamber (12) seal ring is set; Inner sleeve (20) rear end inserts in the joint parent inner chamber (12); Outer cone inclined-plane (31,32) the difference pressurized at packing ring (30) two ends is in the inner cone inclined-plane (23) of inner sleeve (20) and the inner cone inclined-plane (41) of nut (40).
The seal groove (21) of inner sleeve (20) rear end can be narrow type, and corresponding seal ring (22) is the O type, can be 1～3 circle; Seal groove (21a) also can be wide type, and corresponding seal ring (22a) is flat type or wedge type.The latter's sealing surface is bigger, and sealing effect is better.And difficult drop-off when installing.
The front end of inner sleeve (20) inserts and is taken in the road.The front end outside of inner sleeve (20) is provided with seal groove (24) and is with seal ring (25).
Above-mentioned seal groove (24) can be narrow type, and the corresponding seal ring (25) that uses is the O type, can be 1～3 circle, and seal groove (24) also can be broad type, and corresponding seal ring (25) is flat type or wedge type.Latter's sealing surface is big, good sealing effect, difficult drop-off during installation.Wherein, wedge type seal ring front end external diameter is little, be difficult for being scratched by pipeline, and easier installation.
The trough rim of inner sleeve back-end sealing ring recess (21) and/or forward end seal ring recess (24) can be made the indent arcuation, makes that seal ring is more difficult to come off, and guarantees installation quality.
Packing ring (30) is a C type ring, and inboard respectively have raised line (33,37) in two ends, and the centre is provided with 1～3 raised line (34,35,36).The effect of raised line mainly is to improve tensile strength and sealing effect.
Inner sleeve (20) the front end outside also is provided with ring-type sawtooth tooth (26), makes it with more firm by adapter road inwall interlock.
The seal groove (24) of inner sleeve (20) front end and all or part of span that is positioned at packing ring (30) of ring-type sawtooth tooth (26).
The utility model can be made bilateral, threeway or multiple-pass joint as required.
The utlity model has the various advantages of aluminum current plastic composite or joint for plastic tube, and have Good sealing effect, the characteristics such as tensile strength is big. Owing to adopt split-type structural, make installation more Convenient, and the joint parent can be realized unified specification.
