Description
Technical field
The invention belongs to field of agricultural irrigation more particularly to a kind of bypass and installation method for drip irrigation appliance.
Background technology
It is often required to use drip irrigation appliance during agricultural irrigation, drip irrigation zone and trickle irrigation is usually divided into according to shape difference
Pipe.Bypass for drip irrigation zone/pipe is to connect pvc pipe or PE pipes and the connector of drip irrigation zone (pipe), to prevent leak and infiltration,
It needs to punch on pvc pipe or PE tube walls, then rubber washer in hole is installed, finally bypassed through rubber washer and PVC
Pipe or PE pipes are connected.However, on the one hand, conventional rubber washer and bypass is all difficult installation, and under hot weather, PE pipes
Heat expansion is easy to, bypass, which is easy to loosen, infiltration water leakage situation occurs；Another aspect pvc pipe or PE tube walls are than relatively thin
Arc, bypass be bonded with tube wall it is not close, external force act under be easy to rock along tube axis direction and cause infiltration leak.Separately
When outside, using screw screwed connection drip irrigation pipe, since trickle irrigation tube wall is thicker, flexible relatively weaker, installation is relatively difficult, holds
Easily there is infiltration leak even obscission.
Invention CN104989903A solves the problems, such as that rubber washer is difficult to install, but passes through the ladder of binding nut front end
Shape latch can not sealing because inserting paragraph is bonded not close, the footpath of trapezoidal latch and pipe outer wall with inside pipe wall axial direction
It is bonded to direction not close, it is easy to form penetrating passage and leak of seeping water, meanwhile, which is also easy along tube axis direction
Rock, particularly under hot weather, since PE pipes heat expansion deforms, bypass and easily loosen, outer masterpiece in addition can come off,
Infiltration leak can be caused.
Therefore, it is necessary 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.
The content of the invention
To solve problem above, the present invention provides a kind of bypass for drip irrigation appliance, by head, T-shaped waterstop pad, interior
Silk nut, afterbody and snap ring composition, are provided with circular hole on the tube wall of the pipeline, the head generally tubular, one end it is outer
Wall is provided with screw thread, forms silk outside head, and the other end is sticked in the circular hole opened on the tube wall of cylindric pipeline；The T
Shape waterstop pad is formed by connecting by arc sealing piece and cylindricality sealing cylinder, forms T-shaped, the one side of the arc sealing piece be with it is described
The arc that the radian of pipeline outer wall matches, another side is plane and is connected with the cylindricality sealing cylinder, the T-shaped sealing cushion cover
Outside the head, the arcwall face of the arc sealing piece props up the outer wall of the pipeline and is bonded with the outer wall of the pipeline；
One end inner wall smooth of the internal thread nut is sleeved on outside the cylindricality sealing cylinder and end and props up the flat of the arc sealing piece
Face, be provided on the inner wall of the other end with the matched screw thread of screw thread outside the head on silk, and be bolted in outside the head
On silk；The afterbody is made of tail connector and rear body, is provided on the tail connector inner wall and the head
The matched screw thread of screw thread of outer silk, and be bolted in outside the head on silk, the rear body connects with the tail connector
It connects, and away from the head, the outer diameter of one end that the rear body is connected with the tail connector is less than away from described
The outer diameter of one end of tail connector；The snap ring is sleeved on the rear body, and the internal diameter of the snap ring is more than described
The minimum outer diameter of rear body, less than the maximum outside diameter of the rear body.
The bypass can be general with drip irrigation zone and drip irrigation pipe, drip irrigation zone or drip irrigation pipe is locked using snap ring, without in pvc pipe
Or installation rubber washer in the pore of PE pipes, installation difficulty is reduced, it is easy for installation.The arcwall face of T-shaped waterstop pad and pipeline
Outer tube wall fits closely, and after tightening internal thread nut, can prevent bypass caused by being rocked under external force along pipe axis
Infiltration leak.
Further, the one end for being not provided with screw thread on the head is by the mainboard of two pieces of spaced arcs and two pieces
The secondary plate composition of arc, forms tubular, and one end of the mainboard is connected with the silk head outside, other end outward bending formation and
The card of the axis oriented normal on the head, one end of the secondary plate are connected with silk outside the head, and other end outward bending is formed
The card tip at an acute angle with the longitudinal axis on the head, the head prop up the inner wall of the pipeline by the card and the card tip
And engage with the circular hole, the radian in the face of the direction inner-walls of duct of the card tip and card is kissed with the inner wall of the pipeline
It closes.
The setting of one side card and the card tip is more convenient installation, on the other hand, the direction pipeline of the card tip and card
The inner wall of the radian in the face of inner wall and the pipeline, which coincide, enables card and the card tip to be fitted closely with inner-walls of duct, prevents side
Logical leak of seeping water caused by being rocked under external force along pipe axis.In addition, the volume size of the card tip, card with it is traditional
Insertion end volume is bypassed compared to small, the influence to the discharge capacity of pipeline is relatively small.
Further, length of the end away from its bending place of the card tip is more than the width of the card.The setting makes card
The tip can play the role of fine supporting role, under external force drawing, bypass be not easy to loosen and come off, and with the deformation of PE pipes
It is consistent, leak of seeping water can be caused to avoid gap is generated.
Further, two blocks of secondary plates are flexible, can mutually be drawn close under external force extruding, in order to install.
Preferably, the pipeline is PE pipes or pvc pipe.
Further, the outer diameter of the cylindricality sealing cylinder is from one end that the arc sealing piece is connected to away from the arc
One end of shape sealing piece is gradually reduced, and the internal diameter of the inner wall smooth section of the internal thread nut is gradually reduced from end to centre,
Formed it is horn-like, and the maximum inner diameter of one end of the inner wall smooth of the internal thread nut be greater than or equal to the cylindricality sealing cylinder
Maximum outside diameter.The setting can prevent the infiltration leak of card tip two sides.
Further, annular slot is provided on the outer surface of the rear body, in favor of being prevented in installation process
Drip irrigation zone or drip irrigation pipe slip between snap ring and afterbody.
Further, the internal diameter on the head is equal with the internal diameter of the afterbody, so that current smooth-going in bypass, reduces water
Flow the pressure to bypassing associated components.
Further, protrusion is evenly arranged on the outer surface of the internal thread nut, tail connector or snap ring, in favor of
Corresponding component is tightened in installation process.
