Abstract

The utility model provides a trickle irrigation adapter, which is composed of a trickle irrigation adapter body, a rubber ring and trickle irrigation internal teeth. One end of the rubber ring is a stop surface, and one the other end is a stop ring with a stop surface inside. One end of the trickle irrigation adapter is provided with an elastic claw and a stop protrudent ring which can thread pass through the interior of the rubber ring and are stopped by the stop surface of the rubber ring. The stop protrudent ring is stopped by the stop surface in the rubber ring; the other end of the is provided with fastening steps and thread which is matched with the internal thread of the trickle irrigation internal teeth. The trickle irrigation adapter has the advantages that as the rubber ring and the trickle irrigation adapter body are connected with a PVC hard pipe, the trickle irrigation adapter is installed conveniently and is sealed well; the trickle irrigation internal teeth and the trickle irrigation adapter body are connected and fastened with a trickle irrigation belt through inverse thread conveniently and quickly with high sealability, thus preventing the trickle irrigation internal teeth and the trickle irrigation belt from falling off, and dispensing being free of with the required subsidiary products during installation.

Description

The drip irrigation crossover sub

Technical field

The utility model relates to a kind of pipeline connecting head, the crossover sub that particularly a kind of stereoplasm tube pipeline is connected with branch drip irrigation zone pipeline.

Background technique

The main PVC stereoplasm tube pipeline common in the irrigation field do not have the special-purpose crossover sub that is connected with lateral, is to be with tooth line pipe fitting or to pass through the gluing box-like pipe fitting of PVC mostly, uses quite complexity like this, and uses special PVC glue, brings very big inconvenience to installation.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of drip irrigation crossover sub is provided, and makes it can the main PVC stereoplasm tube of convenient, fast connection pipeline and branchs drip irrigation zone pipeline, prevents the interior odontoptosis of drip irrigation simultaneously.

The utility model solves the problems of the technologies described above the technological scheme that is adopted:

The drip irrigation crossover sub, form by tooth in drip irrigation crossover sub main body, rubber grommet, the drip irrigation, described rubber grommet one end is a confined planes, one end is a limited ring, interior band confined planes, described drip irrigation crossover sub main body one end band elastic claw and spacing prominent ring, can pass in the rubber grommet empty and spacing by the confined planes of rubber grommet, spacing prominent ring is spacing by confined planes in the rubber grommet, the other end tight step with lock and screw thread, and screw thread is connected with the screw-internal thread fit of tooth in the drip irrigation.

Above-mentioned screw thread is for falling screw thread.

Compared with prior art, advantage of the present utility model is:

Adopt rubber grommet to be connected with PVC stereoplasm tube pipeline with drip irrigation crossover sub main body, easy for installation like this, the sealability height, the interior tooth of employing drip irrigation is connected with the drip irrigation zone with drip irrigation crossover sub main body and adopts screw thread to screw, prevented that interior tooth of drip irrigation and drip irrigation zone from coming off, quick and easy for installation, the sealability height, and saved subsidiary products required in the installation process.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the drip irrigation crossover sub is made up of tooth 4 in drip irrigation crossover sub main body 2, rubber grommet 3, the drip irrigation.

Above-mentioned rubber grommet 3 one ends are that confinedplanes 31, one ends arelimited ring 32, interior band confined planes 33.

Above-mentioned drip irrigation crossover sub main body 2 one end bandelastic claws 21 and spacingprominent ring 23, can pass in the rubber grommet 3 empty and spacing by the confinedplanes 31 of rubber grommet 3, spacingprominent ring 23 is spacing by confined planes 33 in the rubber grommet 3, the other endtight step 24 with lock and screw thread 22, screw thread 22 is connected with the screw-internal thread fit of tooth 4 in the drip irrigation.

As shown in Figure 2, tooth 4 links together in drip irrigation crossover sub main body 2, rubber grommet 3 and the drip irrigation, this moment, drip irrigation crossover sub main body 2 one endelastic claws 21 stretched out outside rubber grommet 3, and strut on therestriction face 31 of rubber grommet 3, drip irrigation crossover sub main body 2 the other ends are screwed by tooth in the drip irrigation 4.

When connectingPVC stereoplasm tube 5 anddrip irrigation zone 6, earlier rubber grommet 3 is inserted in thePVC stereoplasm tube 5, rubber grommet 3limited rings 32 are held on thePVC stereoplasm tube 5 and stop rubber grommet 3 to be fallen in the PVC stereoplasm tube, again with drip irrigation crossover sub main body 2 anend 21 pass rubber grommet 3 inside to theelastic claw 21 of crossover sub main body 2 and open support on the confinedplanes 31 of rubber grommet 3, drip irrigation crossover sub main body 2 spacingprominent ring 23 also was held on the confinedplanes 32 of rubber grommet 3 and rubber grommet 3 was fixedly secured inPVC stereoplasm tube 5 this moment, and by rubber grommet 3 sealing of drip irrigation crossover sub, again tooth 4 in the 6 usefulness drip irrigations of drip irrigation zone is tightened on drip irrigation crossover sub main body 2 the other end fall on the screw thread 22, lockingstep 24 lockings that this moment,drip irrigation zone 6 should be held by drip irrigation crossover sub main body 2, both obtained good sealing, and for example shown in Figure 3.
