Description
Technical field
This utility model relates to a kind of water drinking tube joint, particularly to a kind of extension type water drinking tube joint.
This utility model further relates to the flexible water drinking tube of a kind of sealing.
Background technology
At present, the water drinking tube of a kind of PVC material supplying birds drinking-water that large-scale cultivation factory uses, this pipe
Being mostly 3 meters/root, the waterline overall length that runs through before and after pouity dwelling place mostly at about 120 meters, needs altogether
40 identical water drinking tubes complete the through of whole system by the splicing of several ways.Thus ensure one
End supplies water, and has water to flow through, it is ensured that the amount of drinking water of birds in whole length range.
One problem the most insoluble of drinking-water system existence is how to prevent more than 100 meter long both at home and abroad
The water pipe of PVC material, after splicing, causes waterline after variation of ambient temperature causes water pipe rising-heat contracting-cold
Rise problem that is curved or that disconnect at expansion joint.
Method for preventing waterline from expanding with heat and contract with cold has the most at present: 1, smear at expansion joint sealing ring
The nontoxic lubricant of oiliness, has more than 30 expansion joint in whole piece drinking-water system length, every about root pipe even
Connecing an expansion joint, each expansion joint is internal containing sealing ring, water drinking tube by with insert telescoping connection
After Tou, sealing function is played in the extruding with sealing ring, and water drinking tube moistens internal capable of expansion and contraction dependence of sealing ring
Lubrication prescription reduces friction, and after not having the effect of lubrication after lubricant volatilizees for a long time, whole piece is drunk water
System will all focus on a telescoping connection more easily slided when temperature reduces all of amount of contraction
At Tou, so may result in water drinking tube and come off herein, cause and leak.
Every water drinking tube or often several water drinking tubes join an expansion joint, and plastic material is fixed card and only served handle
Water drinking tube coordinates the effect together with involving with steel pipe, and has friction between water drinking tube, when this frictional force is little
When frictional force at water drinking tube with sealing ring, namely the lubricant at expansion joint volatilizees totally
When, so when ambient temperature reduces, water drinking tube shrinks, and now water drinking tube shrinks and just will not select
Shrink at expansion joint, and be selected at fixing Ka Chu and slide, the profit at whole piece drinking-water system sealing ring
When lubrication prescription mostly volatilizees totally, the stroke of the water drinking tube of about 40 will all focus on sealing gasket and rub
Wiping power is less than that joint of the frictional force between fixing card and water drinking tube, in the most each expansion joint
The stroke that chamber can bear only reaches the stroke of several tubes, when the stroke of tens pipes all collects
In to when at an expansion joint, will produce herein and come off, cause drinking-water system to leak.
2, being that the connecting hose using rubber quality splices each water drinking tube, position, the most each pipe joint portion makes
Clamping with clip, connecting hose material is softer, mostly is rubber quality, and ageing-resistant poor, the use time is the longest,
And easily cause the mouse etc. within pouity dwelling place and bait, cracky, generation is leaked.
Utility model content
Technical problem to be solved in the utility model is to provide the drink of a kind of simple in construction, good sealing effect
Water pipe seals expansion joint.
Technical problem to be solved in the utility model is to also provide for the flexible water drinking tube of a kind of sealing.
For solving above-mentioned technical problem, this utility model provides a kind of water drinking tube and seals expansion joint, bag
Including adapter sleeve, sealing ring and end cap, adapter sleeve is sleeved on outside adjacent two water drinking tube ends, adapter sleeve
Rear end is extended with tubular seals portion, and sealing ring is arranged between the sealing of adapter sleeve and corresponding water drinking tube,
End cap includes the insertion section of tubulose and ring-type stop part, and the sealing of adapter sleeve is stretched in the insertion section of end cap
And between corresponding water drinking tube and be resisted against on sealing ring, the stop part of end cap is resisted against adapter sleeve rear end face
On;
Described sealing ring is V-shaped seal ring, on front side of V-shaped seal ring opening alignment adapter sleeve.
After using such structure, V-shaped seal ring surface is relatively smooth, can be close according to variations in temperature V-type
The lip of seal is fitted with by sealing surface all the time, it is ensured that the sealing between adapter sleeve and corresponding water drinking tube,
Avoid water drinking tube to come off because of poorly sealed, cause generation of leaking.
And when on front side of V-shaped seal ring opening alignment adapter sleeve, V-shaped seal ring can seal inside water drinking tube
Hydraulic pressure and do not produce release, when hydraulic pressure pressure increases, current can retroaction V-shaped seal ring procheilon change
Contact shape and enlarged contact stress, lip with fitted by sealing surface tightr, it is achieved seal more sternly act on.
This water drinking tube seals the adapter sleeve inwall of expansion joint and is extended with position limiting convex ring, and position limiting convex ring is in phase
Between adjacent two water drinking tubes;After using such structure, position limiting convex ring is possible not only to control stretching of water drinking tube

The assembling of head.
Bond between end cap and the sealing of adapter sleeve of this water drinking tube sealing expansion joint and be connected, end cap
Stop part front end face has spilling annular groove;After using such structure, overflow annular groove and be possible to prevent bonding remaining
Glue oozes out, and affects surface aesthetic.
This water drinking tube seals the V-shaped seal ring surface-coated polytetrafluorethylecoatings coatings of expansion joint;Use this
After the structure of sample, by coating the V-shaped seal ring surface more slickness of politef, during installation not
Lubricant need to be added, and avoid drinking-water system to disconnect when the drinking-water system later stage uses, and at sealing gasket
In the case of volume of production is relatively big, share the polytetrafluorethylecoatings coatings expense on each V-shaped seal ring equally relative
Relatively low, the 3% of not enough each sealing ring cost.
For solving above-mentioned technical problem, this utility model additionally provides the flexible water drinking tube of a kind of sealing, including
Body, sealing ring and end cap, body rear end is extended with adapter sleeve, and it is close that adapter sleeve rear end is also extended with tubulose
Envelope portion, sealing ring is arranged in the sealing of adapter sleeve, and end cap includes the insertion section of tubulose and ring-type resistance
Stopper, in the sealing of adapter sleeve is stretched in the insertion section of end cap and be resisted against on sealing ring, the stop of end cap
Portion is resisted against on adapter sleeve rear end face;
Described sealing ring is V-shaped seal ring, on front side of V-shaped seal ring opening alignment adapter sleeve.
Bond between end cap and the sealing of adapter sleeve of the flexible water drinking tube of this sealing and be connected, the stop of end cap
Portion's front end face has spilling annular groove.
The V-shaped seal ring surface-coated polytetrafluorethylecoatings coatings of the flexible water drinking tube of this sealing.
After using such structure, common water drinking tube is sealed by the flexible water drinking tube of this sealing with above-mentioned water drinking tube
Expansion joint integrates, and makes the flexible water drinking tube of this sealing not only have above-mentioned water drinking tube and seals telescoping connection
Head advantage, and when using need not two-way assembling water drinking tube, time saving and energy saving.
