Abstract
The invention discloses an inserted connecting pipe fitting. The pipe fitting comprises a connecting body, wherein an inner side of a port of the connecting body is provided with a reaming section; a connected pipe is inserted and adhered into the reaming section from all ports respectively; an inner wall of the reaming section is provided with annular grooves so as to form an annular boss on the surface of the reaming section; O-shaped sealing rings are arranged in the annular grooves; two or more annular grooves are formed on the inner wall of the reaming section of the connecting body; a cross section of each annular groove is rectangular; and the depth of each groove is greater than the radius of each O-shaped sealing ring. By the inserted connecting pipe fitting, the problems of high pipe crack possibility and influences on sealing reliability due to eccentric clamping and pressing of a clamping and pressing type pipe fitting, and incapability of repairing caused by clamping and pressing failures due to high pulling possibility of the sealing rings during pipe insertion of a semicircular sealing groove in the prior art are solved. The invention has the advantages that: the inserted connecting pipe fitting has high sealing performance and high production efficiency, is convenient to assemble and disassemble, is easy and convenient to operate, and the like.
Description
Technical field:
The present invention relates to pipe connecting component, 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. the tube wall after this kind pressed with the hydraulic tongs card, after card was pressed failure when installing, the joint can't be repaired.
Summary of the invention:
The purpose of this invention is to provide a kind of insertion pipe connection pipe fitting; That the card that mainly solves clamp-press type pipe in the existing technology is pressed is eccentric, tubing is prone to break, influence sealing reliability, and seal ring is prone to be evaded, block the problem such as can't repair of failing of pressing during semicircle seal groove intubate.
Technological scheme of the present invention is:
The insertion pipe connection pipe fitting; Comprise connecting body, described connecting body port inboard is one section reaming section, and 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, the annular recess of described connecting body reaming section inwall setting is two or with on two; The cross section of described annular recess is a rectangle, and the radius of the big what O-ring seals of groove depth.
Described annular recess is two.
The invention has the beneficial effects as follows good seal performance, and mounting or dismounting are convenient, easy and simple to handle, manufacturing efficiency is high: 1. use rectangular recess, available than large size O type circle, form better sealing.This moment, O type circle was compressed in the groove fully, and formed the cylinder sealing between intubate.2. because of the big what O of groove depth type circle radius, O shape circle can not take to outside the groove because of frictional force when intubate was installed, and effectively guaranteed the intubate success.3. by hand can the inlet pipe intubate with Hydraulic power tools, because of the expander section is accurately to process with mould, so it is little all can to guarantee to insert both gaps, back, realization need not block the pressure mode and guarantee its sealability.4. the annular recess of connecting body reaming section inwall setting is two or with on two, is provided with O-ring seals in the annular recess, can be to being connected the sealing of steel pipe horizontal location conclusive evidence.5. the cross section of annular recess is a rectangle, and the radius of the big what O-ring seals of groove depth, can guarantee intubate after O type circle clamp-on entirely in the groove, have 3% above vacancy rate in the groove at least, can guarantee freely to stretch when seal ring expands with heat and contract with cold.
Description of drawings:
The decomposing state structural representation of Fig. 1 embodiment of the invention.
Sequence number among the figure: 1, connecting body, 2, the reaming section, 3, annular recess, 4, annular convex, 5, O-ring seals, 6, connected tube.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the present invention is made further detailed description, but does not constitute any restriction of the present invention:
Referring to Fig. 1, a kind of insertion pipe connection pipe fitting comprises connecting body 1; Described connecting body 1 port inboard is one section reaming section 2, and connected tube 6 inserts in the applying what reaming section 2 from each port respectively, and described reaming section 2 inwalls are provided with annular recess 3; Form annular convex 4 at reaming section 2 tube-surfaces thus, be provided with O-ring seals 5 in the described annular recess 3, described annular recess 3 is two; The cross section of described annular recess 3 is a rectangle, and the radius of the big what O-ring seals of groove depth.
Pipe joint various in style, commonly used having wait that (different) footpath leads directly to, elbow, threeway, four-way link or the like; They all can use structure of the present invention to be connected with the pipe fitting that is complementary.
Embodiment is just for the ease of understanding technological scheme of the present invention; Do not constitute restriction to protection domain of the present invention; Every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technological scheme of the present invention all still belongs within the protection domain of the present invention.
