Abstract
The utility model discloses a pipe protective joint. The pipe body is a composite main body which is composed of a main body, a lining pipe and a casing, and the interior of the pipe body is provided with shoulder holes with conical holes. The outer diameter of the lining pipe is matched with the inner diameter of a pipeline to be connected. The exteriors of both ends of the casing are provided with screw threads, and the middle of the casing presents a hexagonal shape. A double-headed taper sleeve is sheathed in the taper hole of the composite main body, and the inner diameter of the double-headed taper sleeve is matched with the outer diameter of the pipeline to be connected. The tightening of the taper sleeve is screwed with the casing through the screw thread on one end of the composite main body. The loading and unloading of the pipe protective joint can be done by an ordinary spanner rapidly, and the utility model has advantages of favorable sealing effect, no damages of pipelines and aging prevention. The processing of the screw threads on the pipeline to be connected is not needed, and the pipe protective joint is applicable for various pipelines.
Description
The utility model relates to a kind of pipe joint, the Pipe protective joint that can protect pipeline that especially a kind of common wrench can be loaded and unloaded fast.
Present pipe joint mainly comprises body, which is provided with connecting thread, waits during installation to take over and all need open tooth, and for guaranteeing that sealing also must use attachments such as flax silk, adhesive plaster, operation is loaded down with trivial details when plugging into, easy-maintaining not, and versatility is poor.In the recent period multiple pipe joint occurred, designed for guaranteeing not leak and can plug on the one hand, but often ignored protection, dwindled the increase pipeline pressure as the latus rectum of vast scale to pipe piece with aluminium plastic composited tube for overcoming the drawback that existing old-fashioned pipe connector exists; For anti-leak must increase coupling mechanism force, bear the limit on the other hand, lose due tensile strength but lock too small the causing in position above pipeline, quickened ageing of plastics, and disposable locked, can't reuse during maintenance, soft, hard tube is used all can not compatibility etc.
The purpose of this utility model provides the Pipe protective joint that a kind of common wrench can be loaded and unloaded fast, and its sealing effect is good, and pipeline is not had damage, can prevent to wear out, and treats the adapter road and need not screw thread processing, is suitable for different pipelines.
The purpose of this utility model is achieved in that a kind of Pipe protective joint, comprise body, body is formed the composite host of one by main body, internal lining pipe and shell, and its inside is provided with the shoulder hole of band conical bore, and the external diameter of internal lining pipe matches with the internal diameter of waiting to take over; The outside, two ends of shell is provided with screw thread, and the middle part is hexagon, and suit the double end tapered sleeve in the taper hole of composite host, and the internal diameter of double end tapered sleeve matches with the external diameter of waiting to take over; Fastening tapered sleeve screws by the screw thread and the shell of one end.
The tapering of the outside tapering in two of described double end tapered sleeve and composite host that cooperates with it and fastening tapered sleeve coincide.
The endoporus that described double end tapered sleeve cooperates with road to be taken over is provided with the circular groove that many anti-sealings, gas enter.
The outer end of described double end tapered sleeve has many and waits branch groove lobe.
The through hole of described fastening tapered sleeve termination is greater than the external diameter of the pipeline of waiting to plug into.
Main body, internal lining pipe and shell are that steel is moulded composite host.
One end of stainless steel inner lining tube stretches in the plastics fixing.
Composite host is injected into one with non-toxic plastic and stainless steel casing and stainless steel inner lining tube.
Internal lining pipe has one section pawl.
First hole of shoulder hole is a cylindrical hole, and second hole is a conical bore.
The utility model is because many circular grooves of double end tapered sleeve internal diameter and wait distinguish that the equilibrium of pipe piece is oppressed, the annular groove of falling the zigzag fashion on pipe piece and the liner pipe fitting is fitted tightly, pressurized is even, pressure-bearing surface is big, pressure is little, pipe piece is at all harmless, and anti-fully sealing, gas and ultraviolet intrusion, the effect that reaches sealing and prevent to wear out has especially been played unique protective action to aluminium plastic composited tube, plastic tube, Stainless Steel Tube and internal lining pipe; Because of adopting screw thread to screw, do not need special tool(s) during use, load and unload laborsavingly, quick, expose part and all adopt stainless steel material, elegant in appearance.To different pipe pieces, change the Pipe protective joint accessory size, all can reach ideal and plug into, general wide.
Describe a kind of concrete structure and working principle of Pipe protective joint in detail below in conjunction with accompanying drawing.
Fig. 1 is an axial sectional view of the present utility model;
Fig. 2 is a partial sectional view of the present utility model;
Fig. 3 is the enlarged view of pawl 51 among Fig. 2;
Fig. 4 is the A place partial enlarged drawing of Fig. 2;
Fig. 5 is the B-B sectional view of Fig. 2.
As shown in Figure 1, Pipe protective joint described in the utility model mainly comprises composite host 3, fastening tapered sleeve 1 and double end tapered sleeve 2, and composite host 3 is formed one by main body, shell 4 and internal lining pipe 5.
As shown in Figure 2, composite host 3 is moulded composite host 3 for ad hoc steel, it uses non-toxic plastic as main body, be injected into one with stainless steel casing 4 and stainless steel inner lining tube, composite host 3 is provided with the inner small and outside big shoulder hole that has taper hole of hollow, an end 52 of stainless steel inner lining tube 5 is stretched in the plastics fixedly positioning, and the other end of internal lining pipe 5 has one section pawl 51, as shown in Figure 3, the external diameter of internal lining pipe 5 (have pawl part outer end) is complementary with the internal diameter of waiting to take over 6; The outside, two ends of stainless steel casing 4 is provided with corrugated thread 41, and its middle part is the fixing hexagon of convenient wrench, and its inside is inner small and outside big taper hole 31, and suit double end tapered sleeve 2 in taper hole 31, waits to take over 6 between double end tapered sleeve 2 and stainless steel inner lining tube 5; Fastening tapered sleeve 1 screws togather by the corrugated thread and the stainless steel casing of one end, makes steel mould composite host 3 and screws the balanced work of locking the pipeline of plugging into of finishing with fastening tapered sleeve 1.
Wherein, the tapering of the outside tapering in two of described double end tapered sleeve 2 and main body 3 that cooperates with it and fastening tapered sleeve 1 coincide, double end tapered sleeve 2 with wait that taking over 6 endoporus that cooperate is provided with the circular groove 22 that many anti-sealings, gas enter, the outer end has many and waits branch groove lobes 21, as shown in Figure 5.
The through hole 11 of the termination of fastening tapered sleeve 1 is bigger slightly than the external diameter of the pipeline 6 of waiting to plug into, as shown in Figure 4, fastening tapered sleeve 1 screws back compressing double end tapered sleeve and makes pipeline 6 sealings of plugging into, and prevents and reduces ultraviolet intrusion, reduce the ageing of plastics in the connecting parts, improve working life.
During use, the part of the shell of composite host 3 and fastening tapered sleeve 1 screws togather, double end tapered sleeve 2 is put into composite host 3 and fastening tapered sleeve 1, to wait to take over 6 then inserts outside the internal lining pipe 5 of double end tapered sleeve 2 and composite host 3, when waiting that taking over 6 front ends props up the end wall of composite host, rotate fastening tapered sleeve 1 with spanner, make it to screw with the corrugated thread of shell 4, because the effect of the conical surface, it can balancedly push double end tapered sleeve 2, the balanced again extruding of double end tapered sleeve 2 pipeline to be plugged into is promptly finished and the plugging into of pipe piece.
