Description
Technical field
The utility model is a kind of corrugated pipe coupling, is widely used in the gas of petrochemical industry, liquid transmission pipeline field.
Background technique
Petrochemical industry use pipe coupling, disclosed in CN1619201A " bellows with connector portions ", be formed at tube wall end side connector portions internal face on, arrange be made up of thin metal plate gang up with sheet.Sheet will be ganged up with by utilizing the protuberance of docking side bellows to revolt its elastic force outward direction and push open, thus allow that docking side bellows is to the insertion in connector portions, and by making to gang up with in the gap between adjacent protuberance that sheet utilizes its elastic restoring force to be embedded into the docking side bellows inserted in connector portions, make it sealed with protuberance, thus stop docking side bellows to come off from connector portions.Thus, connector portions can be suppressed to stretch out more outward than the protuberance of tube wall as far as possible, reliably prevent from docking coming off of side bellows, simplify attended operation, and can not counteract when forming porous pipeline.
After this bellows connects, the structure that inside takes the shape of the letter U can cause the generation of eddy current, and adopts the structure of U-shaped that the structural strength of pipe coupling also can be caused to decline.
For another example CN202209487U disclosed " a kind of corrugated pipe connector and bellows ", the head end of described bellows and tail end are provided with helical otch, and described bellows head end is connected with one end of head end joint, and the tail end of described bellows is connected with one end of end connector; Described head end joint and surface, bellows joint are provided with spiral chute, and the spiral chute of described head end joint agrees with mutually with the helical otch of bellows head end; Described end connector and surface, bellows joint are provided with spiral chute, and the spiral chute of described end connector agrees with mutually with the helical otch of bellows tail end.Carry out being connected owing to adopting spiral helicine otch and spiral chute between bellows with joint and coordinate, after bellows coordinates with head end joint and end connector, the connection of bellows and head end joint and end connector can be made substantially firm; And then weld with the joint of pipeline at joint, joint and pipeline are reached and is completely fixed.
This bellows structure adopts worm structure, is connected by the pipeline at two ends, and this pipe connecting structure easily produces the problem of leaking in the process of sealing.
So, based on foregoing, design a kind of sealing configuration good, do not produce leakage, and the pipe joint structure that structural strength is high, be the technical problems to be solved in the utility model.
Model utility content
