The product has good sealing performance and the service life of the product can be prolonged.
Description
Technical field
The utility model relates to a kind of stainless steel sealed pipe joint, and especially a kind of stainless steel is strengthened two face seal pipe joints of buckling that block.
Background technique
Mainly contain following several as thin-walled stainless steel tube bayonet joint method at present: a kind of is disclosed gluing formula thin wall stainless steel pipeline seal adhesive connecting method in publication number CN1587777A patent.Its pipe fitting is made up of pipe fitting and seal ring.The joint socket of pipe fitting is the little taper shape of outer imperial palace, conjointly is provided with an annular groove with the inner of this taper shape minimum, and seal ring is housed in the groove.The end of pipe has a taper shape with conicity for what be complementary with the pipe fitting joint socket.Tube end inserts in the joint socket of pipe fitting, and tube end passes seal ring, and forms the bonded structure of conical surface socket between these two inside and outside circle conical surfaces by adhesive.Another kind is a disclosed injection rubber type thin wall stainless steel pipeline seal adhesive connecting method in publication number CN1916470 patent.Its pipe fitting is made up of pipe fitting and seal ring.The joint socket of pipe fitting is cylindrical, conjointly is provided with an annular groove in joint socket the inner, and seal ring is housed in the groove.On described groove that seal ring is housed and the joint socket between the joint socket outer end, be provided with a hemispherical hollow projection, on this hemispherical hollow projection, have a hole for injecting glue.Pipe inserts in the joint socket of pipe fitting, and tube end passes seal ring.Hole for injecting glue on joint socket is injected adhesive then, thereby forms the adhesive structure of cylndrical surface socket.Also having a kind of is that the thin-walled stainless steel tube card that generally adopts is both at home and abroad pressed connection method.Built-in seal ring in the pipe fitting joint socket, pipe inserts in the joint socket of pipe fitting, after tube end passes seal ring, blocks pressure with the card pressing tongs in the one or both sides of seal ring, then pipe and pipe fitting produce distortion simultaneously because of being squeezed, thereby realize that pipe is connected with the tight of pipe fitting.
The socket and spigot joint method that existing pipe joint adopts, in its joint socket pipe and pipe fitting all have the slit, easily come off, profile defective not attractive in appearance or the like.For thin-wall stainless steel pipe and the most frequently used 0Cr18Ni9 stainless steel material of pipe fitting, be easy to generate crevice corrosion herein most, thereby influence the working life of thin-wall stainless steel like this.Therefore, there is defective in existing pipe joint, need improve.
The model utility content
The purpose of this utility model is to improve on the structure of existing pipe joint, provides a kind of and seals stainless steel better and that can prolong product working life and strengthen two cards face seal pipe joints of buckling.
Stainless steel of the present utility model is strengthened two face seal pipe joints of buckling that block and is had tubing and pipe fitting, described tubing and pipe fitting cooperatively interact, it is characterized in that described tubing one end outer wall has ring packing ring recess and ring packing compression groove, be equipped with O-ring seal in the described ring packing ring recess, the outer wall of described tubing and the inwall of pipe fitting adapt.Described pipe fitting both can be connected with tubing by an independent end, also can be connected with two tubing respectively at two ends.For example described pipe fitting has first connection mouth and second connection mouth, pipe fitting inner wall between described first connection mouth and second connection mouth has spacing preiection portion, described tubing is made of the first tubing unit and the second tubing unit, the outer wall of the described first tubing unit and the first connection mouth inwall adapt, and the outer wall of the described second tubing unit and the second connection mouth inwall adapt.The spacing preiection portion that described pipe fitting inner wall has can allow two tubing unit contact spacing preiection portion two ends respectively and position, and effectively guarantees reliability and accuracy that pipeline connects.
O-ring seal described in the utility model is that the employing cross section is the O-ring seal in banded curved surface (approximate rectangular cross section).After described O-ring seal is extruded distortion, can be between pipe fitting and tubing fitting area bigger, strengthen the sealability between pipe fitting and the tubing significantly, obviously be better than the seal ring of the cross section O type used always.After carrying out crimping, the seal compression groove is banded, further strengthens water-stop.
Use stainless steel of the present utility model to strengthen two the card when buckling the face seal pipe joint, allow described tubing insert pipe fitting earlier, allow the ring packing ring recess and the ring packing compression groove of tubing be nested with in pipe fitting, press connection method by existing pipeline card then, allow pipe fitting respectively in the ring packing ring recess and the position extrusion of ring packing compression groove of tubing.At this moment, the pipe fitting inner wall extruding O-ring seal of being out of shape at ring packing ring recess place also allows it closely contact with tubing ring packing ring recess with pipe fitting inner wall, thus the looping sealing strip.Simultaneously, pipe fitting inner wall in the distortion of ring packing compression groove place closely contacts with tubing ring packing compression groove, further enhanced leaktightness effect, and strengthened the structure stability that pipe fitting is connected with tubing, make between tubing and the pipe fitting more firm, be not easy to become flexible, thereby prevent between tubing and the pipe fitting because vibrate the working life that gets loose the generation corrosion and influence product.Under another kind of Placement, promptly allow two tubing unit be connected with the pipe fitting two ends respectively and contact pipe fitting spacing preiection portion two ends and position, can effectively guarantee reliability and accuracy that pipeline connects, the installation process is further accelerated in convenient definite tubing ring packing ring recess and ring packing compression groove residing position in pipe fitting.
Mentality of designing of the present utility model also is: be provided with two grooves in the pipe outer end, a groove is as seal groove, be used to place seal ring, the another one groove compresses preformed groove the most, pipe is inserted by the pipe fitting joint socket, seal by seal ring and pipe fitting, advance inlet pipe road card pressure between described two grooves with the card pressing tongs then.The compression preformed groove is set, reduces crimping strength, and guarantee that compression puts in place, further improves the anti-pulling ability of crimping rear tubular member tubing.Pipe fitting, tube forming are processed more simple easily than other structural types, and yield rate is high, reduces production costs greatly.Crimping rear tubular member tubing experimental pressure reaches more than the 10.0MPa, does not have infiltration, no drawing sliding phenomenon, and reliability is higher.
Compared with the aforementioned existing similar products, it is better and can prolong product working life that stainless steel of the present utility model is strengthened the face seal pipe seal of buckling of two cards.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
