Abstract
The utility model relates to a self-adaptive pipe joint, which comprises a pipe inner sleeve and a pipe sleeve body with a screw thread on one end, wherein a retainer ring is assembled between the pipe inner sleeve and the pipe sleeve body, and an oblique plane of the outer diameter of the retainer ring is respectively matched with the oblique plane of the pipe inner sleeve and the inner oblique plane of the pipe sleeve body. The self-adaptive pipe joint is characterized in that two or more than two compression buffer tanks are respectively and evenly distributed on two ends of the retainer ring in a crossed mode. The self-adaptive pipe joint not only can adapt same pipes with diversified sizes and specifications, but also can adapt plastic pipes with different types, the connection is convenient, safe and reliable, and the self-adaptive pipe joint has better adaptability and market prospect.
Description
Technical field
The invention relates to the pipeline connection area, is specifically related to a kind of pipe joint interconnection technique.
Background technique
The domestic construction industry development is rapid, and plumbing, the innovation of hot and cold water art and product replace also constantly accelerating, and replace Coating Steel Pipe gradually as flexiplastic tubing such as aluminium-plastic composite pipe, PE-X, PB.The appearance of novel tube has also driven the development of supporting joint interconnection technique.The flexiplastic Manifold technology of prior art such as Chinese notification number are a kind of aluminium-plastic composite pipe pipe coupling of CN 2499672Y, this joint comprises a joint core pipe and a seal ring, be with C type ring in joint core pipe outside, be with nut, between nut and joint core pipe, packing ring is housed in C type ring outside.It is comparatively strict that the joint tubing of prior art connects specification, as the joint of 20 specifications can only supporting 20mm specification pipe, and the pipe wall thickness also has certain requirement.The tubing specification that domestic tubing manufacturing enterprise produces is variant, causes the versatility of pipe fitting poor, the joint problem such as not in place that gets loose or be threaded often occurs and causes the phenomenon of feedwater piping " run, drip, leak ".
Summary of the invention
The invention is diversified in specifications at existing domestic and international tubing, joint cooperates demanding defective, design and comprise that one is provided with the pipe joint of the snap ring of a plurality of compression dashpots, the size that can be tightly connected differs bigger pipe, improves the adaptivity of traditional jointing to pipe.
The technological scheme that the invention is adopted is:
A kind of self adaption pipe joint, this joint comprises cover in the pipe, hold threaded pipe box body one by one, in pipe, be equipped with a snap ring between cover and the pipe box body, snap ring external diameter inclined-plane cooperates with inclined-plane in pipe interior cover inclined-plane and the pipe box body respectively, it is characterized in that uniform each two or more compression dashpot of snap ring two ends intersection.
The invention all right:
" V " font or " U " font that compression dashpot forming shape on the described snap ring is unified.
Compression dashpot on described snap ring one end is 2 to 8, preferred 4.
Described snap ring is provided with otch.
Described snap ring adopts the engineering plastics material, preferred nylon material.
Described snap ring adopts metal material, preferably copper alloy material.
The self adaption pipe joint of the invention has been adjusted the structure and the material of snap ring with respect to traditional pipe joint, can adapt to the diversity of domestic and international tubing specification, and can satisfy the safety reliability of pipe-line system.Have advantages of high practicability and market prospects preferably.
Description of drawings
Fig. 1 partly cuts open schematic representation for the self adaption pipe joint of the invention;
Fig. 2 is the snap ring schematic perspective view of the invention;
Embodiment
Below in conjunction with drawings and embodiments the invention is further described.
As shown in Figure 1, the self adaption pipe joint of the invention comprises cover 1 in the pipe, hold threaded 20 pipe box body 2 one by one, in pipe, be equipped with a snap ring 3 between cover 1 and the pipe box body 2, snap ring 3 external diameter inclined-planes 30 respectively with pipe in cover 1 inclined-plane 10 and the pipe box body 2 inclined-planes 21 cooperates, snap ring 3 two ends intersect uniform each compress dashpots 31.
The inside indentation of described pipe box body 2 its front ends, inwall forms inclined-plane 21 in; At the right-hand member of pipe box body 2 is one to be provided with internal thread 20, according to the screw thread of connecting end 5, can be arranged to internal thread or outside thread; Can be provided with hexagonal or anistree part in the outside of pipe box body 2, make things convenient for being wrenched of pipe fitting.
As shown in Figure 1, 2, described snap ring 3 is annular solids that two ends have inclined-plane 30, and inclined-plane 30 parts contact with the inclined-plane 10 of the interior cover 1 of pipe and the interior inclined-plane 21 of pipe box body 2 respectively; Uniform each two or more compression dashpot 31 of snap ring 3 two ends intersection.Compression dashpot 31 is unified or similar " V " font of shape or " U " font fluting, the fluting bottom most position is near snap ring 3 medium lines, the openings of sizes of compression dashpot 31 is relevant with fluting quantity with adaptation tubing specification, general openings of sizes is between 1mm～6mm, as when connecting the De16 pipe, slotting, number is monolateral opens 4, and openings of sizes is about 2.5mm.Dashpot is monolateral can have 2 to 8, preferred 4 in compression.Described snap ring is provided with otch 32, and otch 32 positions can be arranged on the compression dashpot 31 or on non-compression dashpot 31 positions.
Snap ring 3 can adopt engineering plastics such as PPS, PA, PPUS, preferentially selects nylon (PA) material for use, as Reinforced Nylon etc., to realize having higher intensity and heat resistanceheat resistant performance.Snap ring 3 also can adopt metal materials such as copper, spring steel, Cuprum alloy, and preferably copper alloy material is as brass.Has higher compressibility.
During installation, pipe is inserted in the pipe in the cover 1, will be assemblied in snap ring 3 compressions in the cover 1 and pipe box body 2 in the pipe, make snap ring 3 two ends, clamp tubing owing to be provided with compression dashpot 31 its internal diameters and diminish by pipe box body 2 and connecting end 5 screw connection structures.Pipe under the De32 specification, self adaption pipe joint can be fit to the internal diameter error at 0.5～1mm, and the various plastic tubes of external diameter error in 1～4mm are as aluminium-plastic composite pipe, PEX pipe, PB pipe etc.
The self adaption pipe joint of the invention can not only adapt to the multifarious similar tubing of Dimensions, can also adapt to dissimilar plastic tubes, and is easy to connect, safe and reliable, has applicability and market prospects preferably.
