Abstract

The utility model relates to a combined PE (Poly Ethylene) tee joint for a drip irrigation tape. The combined PE tee joint comprises a tee joint main body and is characterized in that lock catch nuts are respectively arranged at two straight-through ends of the tee joint main body, a spiral head is arranged at the through end, and a spiral head wrench nut is arranged on the spiral head. The combined PE tee joint for the drip irrigation tape has the advantages of simple structure, favorable performance and convenience in installation and operation.

Description

The PE threeway is used in a kind of combined type drip irrigation zone
Technical field
The utility model relates to the agricultural water-saving irrigation equipment technical field, relates in particular to a kind of combined type drip irrigation zone and uses the PE threeway.
Background technique
China is since the pilot demonstration of the drip irrigation technique eighties in 20th century, and the nineties, the drip irrigation economize technology obtained comprehensively popularizing.The installation of drip irrigation system mainly is made up of stem filtration system, underground main pipe, face of land pipe network and drip irrigation zone etc.Face of land pipe network generally adopts the PE flexible pipe to lay, and is used for and being connected of drip irrigation zone.
The drip irrigation zone is one of critical component that face of land pipe network is connected with the drip irrigation zone in the drip irrigation system with threeway.Because the flexible polyethylene manufacture of materials is all adopted in PE flexible pipe and drip irrigation zone, through solar radiation, material can be soft more in installing and using process for it, and this gives installation and uses and all brought inconvenience.Therefore, design a kind of easy to connectly, good seal does not damage the drip irrigation zone of pipe racks again and uses threeway, is the key that guarantees the good operation of drip irrigation system.
Traditional drip irrigation zone adopts following mode to connect with the PE threeway usually: seal with rubber ring with the flexible pipe connecting end, adopt bell and spigot frame to connect; Adopt bell and spigot frame or screw thread snap close bell and spigot frame to seal with the drip irrigation zone connecting end and be connected.The PE threeway of this structural design; In installation process, need earlier the PE flexible pipe to be carried out tap operation; And bore size requires very strict, and perforate is excessive to be prone to cause tee pipe fitting bad or pipe fitting comes off and leaks with the sealing of flexible pipe joint, and the too small pipe fitting of perforate is installed comparatively difficult, not easy to operate; In addition, in use pass through solar radiation, surface temperature can raise gradually, and it is soft more that flexible pipe becomes, and more is unfavorable for the punching installation, and mounted pipe fitting does not have coupling mechanism force with the flexible pipe joint, easy and hose-off because of its socket joint part.
The model utility content
The utility model technical problem to be solved provides a kind of combined type drip irrigation zone functional, simple in structure, that be convenient to fitting operation and uses the PE threeway.
For addressing the above problem; The PE threeway is used in the described a kind of combined type of the utility model drip irrigation zone, comprises the threeway main body, it is characterized in that: two straight-through in said threeway main body termination branches are provided with buckling nut; Wherein the go side head is provided with spiral head, and this spiral head is provided with the spiral head spanner nut.
Two ends straight-through in the said threeway main body are provided with the hangnail bell and spigot frame, are provided with " Γ " shape draw-in groove in wherein leading to.
Said spiral head spanner nut is provided with convex, and its bottom surface is provided with loop configuration.
Said spiral head is provided with double-deck protruding structure.
The utility model compared with prior art has the following advantages:
1, the utility model and PE flexible pipe connecting end adopt the spiral head structure, in installation process, can directly use the spiral head precession, save the operation of traditional drip irrigation zone with the perforate on the PE flexible pipe of PE threeway installation process; The spiral head spanner nut is installed on spiral head simultaneously, can the utility model and flexible pipe locking be guaranteed flexible pipe and good being connected and sealing of the utility model.
2, the utility model and drip irrigation zone connecting end adopt the buckling nut bell and spigot frame, and the hangnail socket joint of buckling nut and threeway main body can guarantee drip irrigation zone and good being connected and sealing effect of the utility model with the utility model and drip irrigation zone locking.
3, the hangnail bell and spigot frame and the buckling nut at the straight-through two ends of threeway main body closely cooperate in the utility model, can the drip irrigation zone be compressed, and prevent to throw off.
4, the convex of spiral head spanner nut designs that cooperate in the spiral head end face can be with the locking of PE flexible pipe in the utility model, guarantees good sealing and prevent to throw off after making the deliquescing of PE flexible pipe because of solar radiation.
5, the draw-in groove corresponding matching of logical part in spiral head raising structure and the threeway main body in the utility model makes closely fixing being assembled on the threeway main body of spiral head, and the double layer construction of spiral head and threeway main body closely cooperate and realized good sealing effect.
6, the utility model simple in structure, be convenient to fitting operation.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structure and the assembling schematic representation of the utility model.
Among the figure: 1-drip irrigation zone 2-threeway main body 3-buckling nut 4-spiral head spanner nut 5-spiral head 6-PE flexible pipe.
Embodiment
As shown in Figure 1, the PE threeway is used in a kind of combined type drip irrigation zone, comprises threeway main body 2.Two straight-through in the threeway main body 2 termination branches are provided with buckling nut 3, and wherein the go side head is provided with spiral head 5, and this spiral head 5 is provided with spiral head spanner nut 4.
Wherein: two ends straight-through in the threeway main body 2 are provided with the hangnail bell and spigot frame, are provided with " Γ " shape draw-in groove in wherein leading to.
Spiral head spanner nut 4 is provided with convex, and its bottom surface is provided with loop configuration.
Spiral head 5 is provided with double-deck protruding structure.
During use,, and 4 lockings of spiral head spanner nut are installed on spiral head 5 with the 5 precession PE flexible pipes 6 of the spiral head in the utility model; Two ends straight-through in the threeway main body 2 in the utility model are linked to each other with drip irrigation zone 1, and 3 lockings of installation buckling nut get final product.
