Description
Technical field
The present invention relates to the delivery pipe link, relate in particular to a kind of thin-wall stainless steel insertion pipe connection pipe fitting.
Background technique
In the existing technology, the clamp-press type pipe that connects with what thin-walled stainless steel tube INSERTTYPE, in establish connecting body; There is one section reaming section on each port side, is connected two steel pipes and inserts two reaming sections respectively, and the connecting body port inner wall is established ring-type semi-circular recesses and O-ring seals; Tube-surface forms the ring-type teat; The inboard connecting body tube-surface of protuberance becomes six prismatics after pressing tube wall with the hydraulic tongs card, forms the compression type sealing thus.There is following deficiency in this kind clamp-press type pipe: 1) the hydraulic tongs card is pressed the normal off-centre that occurs in back, makes these place's tubing wrinkle and breaks, and makes the compression of O type circle uneven; And because of being compression seal, and O type circle can not synchronous, all influences sealing reliability for this reason.2) the groove cross section is semicircle, need use big O type circle if will improve sealing, also must increase the protuberance height for this reason; If groove is too shallow, circle is big, and O type circle is prone to evaded during intubate.3) tube wall after this kind pressed with the hydraulic tongs card, after card was pressed failure when installing, the joint can't be repaired.What employing was also arranged is a kind of pipe joint and nut thread connecting mode, and the centre adds seal ring sealing.Like Chinese invention patent ZL03225537.3, disclosed a kind of linkage structure that comes to this, its main deficiency is 1) and still need increase by a cover connected element at pipeline junction, like nut, pipe joint, increase cost, less economical; 2) insert in the connection procedure and cause the connection part tube wall deformation, in pipe, be prone to leakage phenomenon during transportation of substances herein; 3) these connected elements and pipeline itself be owing to reasons such as difference on material and structure are prone to by environmental corrosion, thereby make pipeline at first impaired at connection part, reduces working life.
Summary of the invention
The purpose of this invention is to provide a kind of insertion pipe connection pipe fitting that has lining, mainly solve in the existing technology connecting tube and insert in the connection procedure and cause the connection part tube wall deformation, in pipe, be prone to the phenomenon of leakage during transportation of substances.
The objective of the invention is to realize through following technological scheme:
Have the insertion pipe connection pipe fitting of lining, comprise connecting body, described connecting body port inboard is one section reaming section; Connected tube inserts in the applying what reaming section from each port respectively, and described reaming section inwall is provided with annular recess, forms annular convex at reaming section tube-surface thus; Be provided with O-ring seals in the described annular recess, described insertion pipe connection pipe fitting also is provided with lining, and described lining one end has flange; Described connected tube external diameter is identical with flange outside diameter on the lining; Lining inserts in the connected tube, and the connected tube end face pushes against on the flange of lining, and the two is combined into one; The compound body of lining and connected tube inserts in the reaming section of connecting body, places the interior O-ring seals of annular recess of reaming section inwall to be clamped on the compound body of lining and connected tube.
The length of described lining is more than or equal to the reaming segment length of connecting body.
Described reaming section internal diameter is slightly larger than the external diameter of connected tube, and the two is plugged on together with the micro-gap fit system.
The present invention utilizes lining to strengthen the intensity of thin-walled connected tube; Solve in the existing technology and cause the connection part tube wall deformation in the thin-wall connecting road insertion connection procedure; In pipe, be prone to the phenomenon of leakage during transportation of substances; Also can directly utilize the port reaming of pipeline own to block each other and press to connect, to reach the saving pipe connecting part, the purpose that reduces production costs.
The present invention has the following advantages and useful effect: 1) save connected elements such as pipe joint, nut, cost is low, good economy performance; 2) the connection part tube wall is not yielding in the thin-wall connecting road insertion connection procedure, good seal performance; 3) environmental corrosion resisting, anti-hot-tempered, compressive strength is high.
