Description
Technical field
The invention belongs to field of agricultural irrigation, particularly relate to a kind of bypass for drip irrigation appliance and installation method.
Background technology
It is often required to use drip irrigation appliance during agricultural irrigation, is usually divided into drip irrigation zone and drip irrigation according to shape difference
Pipe.Bypass for drip irrigation zone/pipe is to connect pvc pipe or PE pipe and the connector of drip irrigation zone (pipe), for preventing from leaking and seeping water,
Need to punch on pvc pipe or PE tube wall, then rubber washer is installed in hole, finally bypasses through rubber washer and PVC
Pipe or PE pipe are connected.But, on the one hand, conventional rubber washer and bypass are all difficult to install, and under hot weather, PE manages
Being easy to flatulence of heat type, bypass is easy to loosen appearance infiltration water leakage situation；On the other hand pvc pipe or PE tube wall ratio are relatively thin, are
Arc, bypass is not tight with tube wall laminating, is easy to rock along tube axis direction and cause infiltration to be leaked under External Force Acting.Separately
Outward, when using screw screwed connection drip irrigation pipe, owing to drip irrigation pipe tube wall is thicker, flexible relative mistake some, install relatively difficult, hold
Easily occur that infiltration is leaked even obscission.
Invention CN104989903A solves the problem that rubber washer is difficult to install, but by the ladder of binding nut front end
Shape latch cannot sealing because the laminating of inserting paragraph and inside pipe wall axial direction is tight, the footpath of trapezoidal latch and pipe outer wall
To direction, laminating is the tightst, it is easy to forming penetrating passage and seep water and leak, meanwhile, this bypass is also easy along tube axis direction
Rocking, particularly under hot weather, owing to PE pipe flatulence of heat type deforms, bypass easily loosens, and even can come off at External Force Acting, also
Infiltration can be caused to leak.
Accordingly, it would be desirable to a kind of new bypass for drip irrigation appliance, to play the effect of good sealing antiseepage, and this
The bypass of sample is preferably easily installed.
Summary of the invention
For solving problem above, the invention provides a kind of bypass for drip irrigation appliance, by head, T-shaped waterstop pad, interior
Silk nut, afterbody and snap ring composition, the tube wall of described pipeline is provided with circular hole, and described head generally tubular, outside one end
Wall is provided with screw thread, forms the outer silk of head, and the other end is sticked on the tube wall of the pipeline of cylindrical shape in the circular hole opened；Described T
Shape waterstop pad is formed by connecting by arc sealing piece and cylindricality sealing cylinder, forms T-shaped, and the one side of described arc sealing piece is with described
The arc that the radian of pipeline outer wall matches, another side is plane and is connected with described cylindricality sealing cylinder, described T-shaped sealing cushion cover
Outside described head, the arcwall face of described arc sealing piece props up the outer wall of described pipeline and fits with the outer wall of described pipeline；
One end inner wall smooth of described internal thread nut, is enclosed within outside described cylindricality sealing cylinder and end props up the flat of described arc sealing piece
Face, the inwall of the other end is provided with the screw thread contrary with the screw thread on silk outside described head, and is bolted in the outer silk of described head
On；Described afterbody is made up of tail connector and rear body, outside described tail connector inwall is provided with described head
The screw thread that the screw thread of silk matches, and be bolted on the outer silk of described head, described rear body is connected with described tail connector,
And away from described head, the external diameter of one end that described rear body is connected with described tail connector is less than away from described afterbody
The external diameter of one end of connecting portion；Described snap ring is enclosed within described rear body, and the internal diameter of described snap ring is more than described afterbody
The minimum outer diameter of main body, less than the maximum outside diameter of described rear body.
This bypass can be general with drip irrigation zone and drip irrigation pipe, uses snap ring locking drip irrigation zone or drip irrigation pipe, it is not necessary at pvc pipe
Or rubber washer is installed in the pore of PE pipe, and reduce installation difficulty, easy for installation.The arcwall face of T-shaped waterstop pad and pipeline
Outer tube wall fits tightly, and after tightening internal thread nut, is possible to prevent bypass to cause because rocking along pipe axis under external force
Infiltration is leaked.
Further, one end being not provided with screw thread of described head is by the mainboard of two pieces of arcs alternately and two pieces
The secondary plate composition of arc, forms tubular, and the outer silk of one end of described mainboard and described head is connected, the other end be outwards bent to form and
The card of the axis oriented normal of described head, one end of described plate silk outer with described head is connected, and the other end is outwards bent to form
The card tip acutangulated with the longitudinal axis of described head, described head props up the inwall of described pipeline by described card and the described card tip
And engage with described circular hole, the inwall kiss of the radian in the face towards described inner-walls of duct of the described card tip and card and described pipeline
Close.
On the one hand the setting of card and the card tip makes installation more convenient, on the other hand, the card tip and card towards described pipeline
The radian in the face of inwall is identical with the inwall of described pipeline makes card and the card tip can fit tightly with inner-walls of duct, prevents side
The logical infiltration caused because rocking along pipe axis under external force is leaked.Additionally, the volume size of the card tip, card is with traditional
Bypass is inserted end volume and is compared little, and the impact on the discharge capacity of pipeline is relatively small.
Further, the length of its bending place of end-to-end distance of the described card tip is more than the width of described card.This setting makes card
The tip can play fine supporting role, and under external force drawing effect, bypass is not easy to loosen and come off, and with the deformation of PE pipe
Keep consistent, can avoid producing gap and causing infiltration to be leaked.
Further, described two pieces plates are flexible, mutually can draw close, in order to install under external force extrudes.
Preferably, described pipeline is PE pipe or pvc pipe.
Further, the external diameter of described cylindricality sealing cylinder from the one end being connected with described arc sealing piece to away from described arc
One end of shape sealing piece is gradually reduced, and the internal diameter of the inner wall smooth section of described internal thread nut is gradually reduced to centre from end,
Formed horn-like, and the maximum inner diameter of one end of the inner wall smooth of described internal thread nut is more than or equal to described cylindricality sealing cylinder
Maximum outside diameter.This setting can prevent the infiltration of card tip dual-side from leaking.
Further, the outer surface of described rear body is provided with annular slot, is beneficial to prevent in installation process
Drip irrigation zone or drip irrigation pipe slip between snap ring and afterbody.
Further, the internal diameter of described head is equal with the internal diameter of described afterbody, so that current smooth-going in bypass, reduces water
Flow the pressure to bypass associated components.
Further, the outer surface of described internal thread nut, tail connector or snap ring is evenly arranged with projection, is beneficial to
Corresponding parts are tightened in installation process.
