Abstract
The utility model relates to a fast joint for pipes, which is suitable for connecting various pipelines and is particularly suitable for engineering plastic pipelines such as glass fiber reinforced plastic pipelines. The utility model is characterized in that the end parts of pipelines are provided with fixed grooves of which cross sections are in certain shapes, fixed rings are arranged in the fixed grooves, flanges are arranged outside the rings, a sealing ring is arranged between two pipes, and both sides of the sealing ring are matched with the end parts of the pipes. The utility model has the advantages of simple structure, high reliability and convenient on-site construction.
Description
Tubing rapid pipe joint is applicable to mainly and connects various engineering plastics pipelines that the various corrosion-resistant pipeline as glass fibre reinforced plastics is made also is applicable to various metal tubes.
The existing tubing joint of China is divided into flared type and non-flared type two classes.It is several that wherein non-flared type can be divided into welding type, FERRULETYPE, sphere formula, elastic cuffs formula, bolt-type, flange-type etc. again, the common feature of these pipe joints is to be applicable to metal tubes, be not suitable for the engineering plastics pipeline, also do not have a kind of very reliable and easy joint so far in order to connect the engineering plastics pipeline.
The purpose of this utility model is the tubing rapid pipe joint that solves a kind of reliable, easy construction simple in structure, general, mainly is applicable to glass fibre reinforced plastics engineering plastics pipeline, also is applicable to metal tubes simultaneously.
Tubing rapid pipe joint is to realize by the improvement to the fixed block of existing pipe joint, Sealing etc.Drive fixed groove in the pipeline end that need connect earlier, the fixed groove section is divided into rectangle and circle lacks shape two classes.The former is applicable to thin walled tube at the best, and latter's the best is used for thick walled tube.When using this joint, at end 1 to the 3 times of thickness of pipe place open loop shape fixed groove apart from the need connecting pipeline, the section of its groove is that rectangle or circle lack shape, and the degree of depth of groove is 1/6 to 1/3 thickness of pipe, and the width of groove is 1/2 to 3 times of thickness of pipe.Retainer ring is housed in the fixed groove, the shape of its circle, if when cooperating with the rectangle fixed groove, section is a right-angled trapezium, if when circle lacks the shape fixed groove and cooperates, section is a circle.The right-angled trapezium retainer ring is made up of the annulus of 2 to 3 five equilibriums, and circular retainer ring is made up of the annulus of band opening or the annulus of 2 to 3 five equilibriums.The retainer ring cylindrical of fixed groove of packing into should be higher than external diameter of pipe.Flange is equipped with at retainer ring cylindrical place, the even through hole that is furnished with construction bolt on the flange, and there is through hole the center.If during the rectangle fixed groove, the flange center place is conical through-hole, if justify when lacking the shape fixed groove, the center is a ladder hole.The seal ring of section for " worker " font is housed in the middle of two pipes, and " worker " font both sides cooperate with ends of tubes, pass through liquid in the circle.After pipeline was loaded onto flange, retainer ring, seal ring, bolt, nut, fastening nut, the radial component of flange endoporus can make retainer ring be fixed on pipeline, and axial thrust load can compress seal ring, finished the connection and the sealing of pipeline.
Tubing rapid pipe joint is compared with existing tubing joint, and it is simple in structure, part is few, reliability is high, especially to the engineering plastics tubing, adopts tubing rapid pipe joint to connect best results.Retainer ring is put into fixed groove easily, and fixed groove can be processed as required at the scene, so construction and installation are more flexible, changes simply, and dismounting is also convenient again after fixing.Flange endoporus and retainer ring can play positioning action, can play the effect of proofreading and correct the pipeline deviation from circular from again, so the pipeline deviation from circular from is required very not strict.Therefore, more suitable to the relatively poor glass fibre reinforced plastics pipeline of rigidity.Have only seal ring to contact in this joint, just can adapt to different liquids so only need change seal ring with liquid.Itself also can take anti-corrosion measure part such as flange, retainer ring.This joint cost is equivalent to welded fitting, is lower than other kind joint.
The concrete structure of tubing rapid pipe joint is drawn explanation by Fig. 1, Fig. 2, and its Fig. 1 is a rectangle fixed groove tubing quick coupling structure, and Fig. 2 is that circle lacks the rapid pipe joint of shape fixed groove tubing.The pipeline (1) that needs among Fig. 1 to connect is apart from 1 to 3 times of thickness of pipe place of end face, and the face of cut-offfing is the fixed groove (5) of rectangle, and groove depth is 1/6 to 1/3 times of thickness of pipe, and groove width is 1/2 to 3 times of thickness of pipe.The section of packing in the groove is the retainer ring of right-angled trapezium (4), this circle is made of the annulus of 2 to 3 five equilibriums, and retainer ring (4) cylindrical is equipped with flange (2), and flange (2) is gone up the even through hole that is furnished with the dress bolt, there is conical through-hole the center, and its tapering is identical with retainer ring (4) cylindrical tapering.Dress seal ring (6) in the middle of two pipes, when tighting a bolt (3) with nut (7), retainer ring (4) is fixed on the pipe, and seal ring (6) is compacted, finishes the connection and the sealing of pipeline.Shown in Figure 2 and Fig. 1 difference is, the section of fixed groove (5 ') lacks shape for circle, retainer ring (4 ') is made of the annulus of notched annulus or 2 to 3 five equilibriums, flange (2 ') center is a ladder hole, wherein the internal diameter of a through hole is equal to or less than retainer ring (4 ') external diameter, another through hole internal diameter is greater than the pipeline external diameter, and remaining all constructs identical with Fig. 1.
