Description

The insertion pipe connection pipe fitting that has lining
Technical field
The utility model relates to the delivery pipe link, relates in particular to a kind of thin-wall stainless steel insertion pipe connection pipe fitting.
Background technique
In the prior art, clamp-press type pipe with the connection of what thin-walled stainless steel tube plug-in type, 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, after the inboard connecting body tube-surface of protuberance is used hydraulic tongs Ka Yaguanbi, become six prismatics, form the compression type sealing thus.There is following deficiency in this kind clamp-press type pipe: 1) the normal off-centre that occurs in hydraulic tongs card pressure back, and make these place's tubing wrinkle and break, make 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 also must increase the protuberance height with big O type circle if will improve sealing for this reason; If groove is too shallow, circle is big, and O type circle is easily 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.As Chinese utility model 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, as 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 owing to reasons such as difference on material and structure easily by environmental corrosion, thereby make pipeline at first impaired at connection part, reduce working life.
Summary of the invention
The purpose of this utility model provides a kind of insertion pipe connection pipe fitting that has lining, mainly solves in the prior art connecting tube and inserts in the connection procedure and cause the connection part tube wall deformation, is prone to the phenomenon of leakage in pipe during transportation of substances.
The purpose of this utility model is achieved by the following technical solution:
The insertion pipe connection pipe fitting that has 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, described reaming section inwall is provided with annular recess, form 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, described lining one end has flange, and described connected tube external diameter is identical with flange outside diameter on the lining, and lining inserts in the connected tube, 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 utility model utilizes lining to strengthen the intensity of thin-walled connected tube, solve in the prior art 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 mutually and press and connect, to reach the saving pipe connecting part, the purpose that reduces production costs.
The utlity model has following advantage 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, the compressive strength height.
