Description
Technical field
The present invention relates to a kind of water drinking tube joint, particularly a kind of extension type water drinking tube joint.
The invention still further relates to the flexible water drinking tube of a kind of sealing.
Background technique
At present, a kind of water drinking tube supplying the PVC material of bird drinking-water that large-scale cultivation factory uses, this pipe is mostly 3 meters/root, and one runs through waterline overall length before and after pouity dwelling place mostly at about 120 meters, altogether needs 40 identical water drinking tubes to complete the through of whole system by the splicing of several mode.Thus ensure to supply water in one end, there is water to flow through in whole length range, ensure the amount of drinking water of bird.
It is exactly how to prevent the water pipe of more than 100 meter long PVC material after splicing that domestic and international drinking-water system exists a comparatively insoluble problem, cause after variation of ambient temperature causes water pipe rising-heat contracting-cold waterline rise curved or expansion joint place disconnect problem.
The current method for preventing waterline from expanding with heat and contract with cold has both at home and abroad: 1, the nontoxic oiling agent of oiliness is smeared at expansion joint seal ring place, more than 30 expansion joint is had in whole piece drinking-water system length, approximately every root pipe connects an expansion joint, each expansion joint inside is containing seal ring, water drinking tube by with insertion expansion joint after play seal action with the extruding of seal ring, water drinking tube reduces friction at seal ring dependence oiling agent inner capable of expansion and contraction, do not have the effect of lubrication after oiling agent volatilizees for a long time after, whole piece drinking-water system will all focus on expansion joint place of comparatively easily sliding when temperature reduces all contour projector, water drinking tube will be caused like this to come off herein, cause and leak.
Every root water drinking tube or often several water drinking tubes join an expansion joint, plastic material is fixed card and is only played water drinking tube and steel pipe are coordinated the effect together with involving, and there is friction between water drinking tube, when this frictional force is less than the frictional force at water drinking tube and seal ring place, namely when the oiling agent volatilization totally of expansion joint place, like this when ambient temperature reduces, water drinking tube shrinks, now water drinking tube shrinks and just can not select to shrink in expansion joint place, and be selected at fixing Ka Chu and slide, when the oiling agent at whole piece drinking-water system seal ring place mostly volatilizees totally, the extending amount of the water drinking tube of about 40 just all can focus on that joint that sealing gasket frictional force is less than the frictional force between fixing card with water drinking tube, the extending amount that now each expansion joint inner chamber can bear only reaches the extending amount of several tubes, when the extending amount of tens pipes all focuses on expansion joint place, just can produce herein and come off, drinking-water system is caused to leak.
2, be use the soft connector of rubber quality to splice each water drinking tube, position, each like this pipe joint portion uses clip clamping, and soft connector material is softer, mostly be rubber quality, ageing-resistant poor, service time is not long, and the mouse etc. easily causing pouity dwelling place inside baits, cracky, generation is leaked.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of structure is simple, the water drinking tube of good sealing effect sealing expansion joint.
Technical problem to be solved by this invention also provides a kind of sealing flexible water drinking tube.
For solving the problems of the technologies described above, the invention provides a kind of water drinking tube sealing expansion joint, comprise connecting sleeve, seal ring and end cap, connecting sleeve is sleeved on outside adjacent two water drinking tube ends, connecting sleeve rear end is extended with tubular seals portion, seal ring is arranged between the sealed department of connecting sleeve and corresponding water drinking tube, end cap comprises the insertion part of tubulose and the stop part of ring-type, the insertion part of end cap to be stretched between the sealed department of connecting sleeve and corresponding water drinking tube and is resisted against on seal ring, and the stop part of end cap is resisted against on connecting sleeve ear end face;
Described seal ring is V-shaped seal ring, and V-shaped seal ring opening is aimed on front side of connecting sleeve.
After adopting such structure, V-shaped seal ring surface is comparatively smooth, can fit all the time with by sealing surface according to the lip of temperature variation V-shaped seal ring, ensures the sealing between connecting sleeve and corresponding water drinking tube, avoid water drinking tube to come off because of poorly sealed, cause generation of leaking.
And when V-shaped seal ring opening is aimed on front side of connecting sleeve, V-shaped seal ring can seal water drinking tube inside water pressure and not produce release, when hydraulic pressure pressure increases, the procheilon of current meeting reaction V-shaped seal ring changes contact shape and enlarged contact stress, lip with fitted tightr by sealing surface, realize sealing and more sternly act on.
The connecting sleeve inwall of this water drinking tube sealing expansion joint is extended with position limiting convex ring, and position limiting convex ring is between adjacent two water drinking tubes; After adopting such structure, position limiting convex ring not only can control the flexible amplitude of water drinking tube, and can limit the relative position of two water drinking tubes, is conducive to the assembling of this water drinking tube sealing expansion joint.
Adhering junction between the end cap of this water drinking tube sealing expansion joint and the sealed department of connecting sleeve, the stop part front-end face of end cap has spilling annular groove; After adopting such structure, overflow annular groove and can prevent bonding remaining glue from oozing out, affect surface aesthetic.
The V-shaped seal ring surface coating polytetrafluorethylecoatings coatings of this water drinking tube sealing expansion joint; After adopting such structure, slickness is had more by the V-shaped seal ring surface applying teflon, do not need during installation to add oiling agent, and avoid drinking-water system to disconnect when the drinking-water system later stage uses, and when sealing gasket yielding capacity is larger, the polytetrafluorethylecoatings coatings expense of sharing equally on each V-shaped seal ring is relatively low, 3% of not enough each seal ring cost.
For solving the problems of the technologies described above, present invention also offers the flexible water drinking tube of a kind of sealing, comprise body, seal ring and end cap, body rear end is extended with connecting sleeve, connecting sleeve rear end is also extended with tubular seals portion, and seal ring is arranged in the sealed department of connecting sleeve, and end cap comprises the insertion part of tubulose and the stop part of ring-type, be resisted against on seal ring in the sealed department that connecting sleeve is stretched in the insertion part of end cap, the stop part of end cap is resisted against on connecting sleeve ear end face;
Described seal ring is V-shaped seal ring, and V-shaped seal ring opening is aimed on front side of connecting sleeve.
Adhering junction between the end cap of the flexible water drinking tube of this sealing and the sealed department of connecting sleeve, the stop part front-end face of end cap has spilling annular groove.
The V-shaped seal ring surface coating polytetrafluorethylecoatings coatings of the flexible water drinking tube of this sealing.
After adopting such structure, common water drinking tube and above-mentioned water drinking tube are sealed expansion joint and integrate by the flexible water drinking tube of this sealing, the flexible water drinking tube of this sealing is made not only to have the advantage of above-mentioned water drinking tube sealing expansion joint, and need not two-way assembling water drinking tube when using, time saving and energy saving.
