The double-wall corrugated pipe joint disclosed by the utility model ensures the waterproofness of the insertion of the pipes well, is convenient and rapid to mount, and easy to maintain, thereby effectively reducing the connection cost of the pipes, increasing the construction speed and improving the working efficiency.
Description
Technical field
The utility model relates to a kind of engineering plastics bellows field, relates in particular to the double wall corrugated pipe joint that a kind of electric wire pipeline and drainage pipe use.
Background technique
Electric wire pipeline and drainage pipe in power communication adopts corrosion-resistant mostly at present, good insulating, the double-wall corrugated pipe of pressure resistance carries out pipeline construction, owing to making and mode that the needs of construction generally adopt the sleeve pipe spreading couples together different sections double-wall corrugated pipe, connection between the double-wall corrugated pipe mainly adopts enlarging socket joint and sleeve to connect dual mode, its middle sleeve link cost is higher and more complicated is installed, and it is unstable to adopt the enlarging socket joint to connect owing to extruding the enlarging size, very easily cause the connection part infiltration, need to adopt tackiness agent or use anchor ear to hold tightly at connection part, but use such method consumable material large, cost is higher and affect speed of application, and then affects working efficiency.
The model utility content
Complicated for the installation that the prior art double-wall corrugated pipe connect to exist, cost is higher and the problem of poor sealing performance, the utility model provides a kind of simple in structure, stable connection and lower-cost double wall corrugated pipe joint.
In order to solve the problems of the technologies described above, the utility model provides a kind of double wall corrugated pipe joint, comprise that the tubing that is connected that is positioned at two ends is left straight length and right straight length, described left straight length connects by being connected pipeline section with described right straight length, described connection pipeline section comprises end mouth section and flared section, mouth section of the described end and described left straight length are by the end face sweat soldering, described flared section and described right straight length socket joint socket, wherein, described flared section and described right straight length socket joint socket form groove, are provided with at least one elastic seal ring in the described groove.
Wherein, the diameter of described flared section is a bit larger tham the diameter of described right straight length, just inserts described flared section as benchmark take described right straight length.
Wherein, described elastic seal ring is annular, and the shape of cross section of described elastic seal ring is triangle, circle or semicircle.
Wherein, the material of described elastic seal ring is rubber, nylon or plastic with plasticity.
Double wall corrugated pipe joint of the present utility model arranges the multiple tracks elastic seal ring in the groove of the flared section that connects pipeline section and right straight length socket joint socket formation, guaranteed well the water-proof performance of tubing socket joint, quick and easy for installation, safeguard simple, effectively reduce simultaneously the link cost of tubing, improved speed of application and working efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model double wall corrugated pipe joint one preferred embodiment.
Fig. 2 is the local enlarged diagram in A place among Fig. 1.
Embodiment
Describe below in conjunction with the structure of accompanying drawing to double wall corrugated pipe joint of the present utility model.
See also Fig. 1, Fig. 1 is the structural representation of the utility model double wall corrugated pipe joint one preferred embodiment.Double wall corrugated pipe joint of the present utility model comprises that the tubing that is connected that is positioned at two ends is left straight length 1 and right straight length 2, left straight length 1 connects by being connected pipeline section 3 with right straight length 2, wherein, left straight length 1, right straight length 2 and connection pipeline section 3 adopt material of the same race.Connect pipeline section 3 and comprise end mouth section 301 and flared section 302, end mouth section 301 is passed through the end face sweat soldering with left straight length 1, flared section 302 and right straight length 2 socket joints socket, the diameter of flared section 302 is a bit larger tham the diameter of right straight length 2, just inserts flared section 302 as benchmark take right straight length 2.
As shown in Figures 1 and 2, flared section 302 forms groove 5 with right straight length 2 socket joints socket, is provided with the elastic seal ring 6 of at least one annular in the groove 5, so that flared section 302 is eliminated with the gap of right straight length 2, reaches preferably sealing effect.The shape of cross section of elastic seal ring 6 is triangle, circle or semicircle, and the material of elastic seal ring 6 is rubber, nylon or plastic with plasticity, and in the present embodiment, elastic seal ring 6 adopts leg-of-mutton rubber seal.
The using method of double wall corrugated pipe joint of the present utility model is as follows: at first with left straight length 1 face of weld planing to be welded, utilize welding plate that the face of weld of left straight length 1 is heated respectively with end mouth section 301 end face parts that are connected pipeline section 3, exert pressure again both meltings, firmly connect with the end mouth section 301 that is connected pipeline section 3 through cooling rear left straight length 1.Then the elastic seal ring 6 with annular is enclosed within on the outer wall of right straight length 2, right straight length 2 is aimed at the flared section 302 of inserting connection pipeline section 3, so that both socket joints connect, in the outer wall that elastic seal ring 6 is sealed in right straight length 2 just and the groove 5 that the flared section that is connected pipeline section 3 302 mutual socket joints form, play sealing and firmly effect, the flared section 302 that will connect at last pipeline section 3 partly adopts high blowing hot wind welding gun to be aided with welding rod with the socket joint of right straight length 2 to carry out welding, so that both are connected firmly, well guaranteed the sealability of double-wall corrugated pipe.
In the present embodiment, the shape of cross section of elastic seal ring is triangle, the material of elastic seal ring is rubber, certainly, also can according to circumstances adopt other to have the air-supported structure of similar functions, such as circular, semicircle, trapezoidal, semicircle and leg-of-mutton combination, semicircle and trapezoidal combination, trapezoidal and leg-of-mutton combination etc., elastic seal ring also can adopt nylon or plastic with plasticity, in addition, the quantity of elastic seal ring also can be looked actual sealing to be needed to adopt twice or three roads, and those skilled in the art can carry out the phase strain type in conjunction with actual conditions.
Double wall corrugated pipe joint of the present utility model arranges the multiple tracks elastic seal ring in the groove of the flared section that connects pipeline section and right straight length socket joint socket formation, guaranteed well the water-proof performance of tubing socket joint, quick and easy for installation, safeguard simple, effectively reduce simultaneously the link cost of tubing, improved speed of application and working efficiency.
Here description of the present utility model and application is illustrative, is not to want with scope restriction of the present utility model in the above-described embodiments.Here disclosed embodiment's distortion and change is possible, and the various parts of embodiment's replacement and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that in the situation that do not break away from spirit of the present utility model or substantive characteristics, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.In the situation that do not break away from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
