Abstract

The utility model relates to a water saving drip irrigation pipeline structure which belongs to the technical field of hydrotechnics. A pipeline system is composed of a main pipe, a PVC adding interface vertically communicated with the main pipe, a PVC pipe communicated with the PVC adding interface, a PE three-way joint communicated with the PVC pipe, PVC ball valves respectively communicated with two ends the PE three-way joint, PE pipes respectively communicated with the PVC ball valves, pressure flow stabilizers alternately communicated with the PE pipes, and dripping irrigation bands communicated with both ports of each of the pressure flow stabilizers, wherein the main pipe is communicated with a water source. The utility model greatly cuts down the work quantity of installation and drip irrigation, and decreases the building cost of projects; the cost per mu can be saved by about 30 to 50 yuan, so that the economic benefit is very apparent.

Description

A kind of water-saving drip irrigation tube structure

1, technical field: a kind of water-saving irrigation tube structure of the present utility model, belong to the water conservancy project field, relate in particular to farmland water-saving drip irrigation pipe web frame.

2, background technology: water-saving agriculture is just risen in the vast rural area of China, drip irrigation technique has obtained large tracts of land and has promoted, the threeway of take-off line in the drip irrigation pipe network by being communicated with it one by one gone into the irrigate band with hydraulic pressure, and then by the irrigate band one strain strain crop implemented drip irrigation.Existing drip irrigation system need increase by a cover auxiliary branch line and guarantee control to current, and installation and drip irrigation operation are comparatively time-consuming, and cause cost to increase.

3, summary of the invention: the purpose of this utility model is to provide a kind of tube structure that auxiliary branch line is the accurate drip irrigation of practicable water saving that need not.

The utility model purpose be achieved in that the water-saving drip irrigation tube structure by be embedded in the underground person in charge, increase interface, increase the pvc pipe material that interface is communicated with, the PE threeway that is communicated with the pvc pipe material with PVC with the PVC that is responsible for vertical connection, the PVC ball valve that is communicated with respectively with PE threeway two ends, the PE tubing that is communicated with respectively with the PVC ball valve, the pressure flow stabilizer that is communicated with at interval with PE tubing, the irrigate band that is communicated with each pressure flow stabilizer two-port form.

Owing to saved numerous and diverse auxiliary branch line system, so installation of this piping and drip irrigation workload greatly reduce, construction costs reduces, and about every mu of ground cost savings 30-50 unit, economic benefit is fairly obvious.

5, embodiment:

Legend: 1, the outer silk 2 of PVC, PVC increase interface 3, pvc pipe material 4, steel snap ring 5, water stop gel ring 6, PE threeway 7, PVC ball valve 8, the outer silk 9 of positive line socket joint, irrigate band 10, pressure flow stabilizer 11, PE tubing 12, stable pipe 13, silica gel sheath 14, irrigate band joint 15, coupling

Embodiment: shown in figure l, the water-saving drip irrigation piping by be embedded in the underground person in charge, with the PVC that is responsible for vertical connections increase interface 2, by the outer silk 1 of PVC and PVC increase pvc pipe material 3 that interface 2 is communicated with, the PVC ball valve 7 that is communicated with respectively by outside the PVC 1 PE threeway 6 that is communicated with pvc pipe material 3, with PE threeway 6 two ends, the PE tubing 11 that is communicated with respectively by outside steel snap ring 4, water stop gel ring 5 and the positive line socket joint 8 and PVC ball valve 7, the pressure flow stabilizer 10 that is communicated with PE tubing 11 intervals, the irrigate band 9 that is communicated with each pressure flow stabilizer 10 two-port forms.Water stop gel ring 5 is enclosed within on the bell end outer wall of the outer silk 8 of positive line socket joint, and an end of PE tubing 11 is enclosed within on the bell end port of the outer silk 8 of positive line socket joint, steel snap ring 4 is enclosed within on the water stop gel ring 5 again, and steel snap ring 4 is

The shape ring, its opening two ends are connected by the screw rod nut, screw nut, and the openend closure of steel snap ring 4 can closely be nested together PE tubing 11, water stop gel ring 5, the outer silk of positive line socket joint 8 threes.Be responsible for the water source and connect.

As shown in Figure 2, the pressure flow stabilizer by the threeway of T shape and be installed in threeway vertically stable pipe 12 two parts in the pipe form.Producing bell with vertical inside pipe wall of the transverse pipe junction of T shape threeway.Stable pipe 12 is a cylinder, and an end is and the consistent bell of vertical pipe bell tapering that the other end is a round boss.The trihedral that a section is a △ shape is installed at the center in chamber, cylinder middle and lower part, all vertically is connected with a little △ shape trihedral on each face, and three little △ shape trihedral outsides do not link to each other mutually, constitute a water channel between per two little △ shape trihedrals.Four △ shape trihedral upper ends flush, and the lower end also flushes, and its upper end is connected with the lower end of bell, and the upper end of its lower end and round boss is connected, and three mutual disjunct little △ shape trihedral outsides are set with silica gel sheath 13.The lower end of vertical pipe has and vertically manages consistent inlet opening, the center of circle with the coupling 15 that has been threaded, the bottom surface of this joint, and there is a tangentially protruding pipe clamp at place, outer, bottom surface.All have a few external screw threads on the two side transverse pipe tube walls of T shape threeway, the transverse pipe mouth of pipe in the external screw thread outside is tapered.

During assembling drip irrigation pipe network, will stablize pipe 12 earlier and pack in the vertical pipe of T shape threeway, the bell of the two is matched.Again coupling 15 is screwed in the lower end of the vertical pipe of T shape threeway.Leave aperture on branched pipe, the pipe clamp in the coupling 15 is screwed in this aperture, screw the threeway of T shape, coupling 15 can closely be connected on the PE tubing 11.At last, through on the irrigate band 9, irrigate band 9 is enclosed within respectively on the bell at T shape threeway transverse pipe two ends with irrigate band joint 14, and with irrigate band joint 14 rotation direction transverse pipe external screw thread places, irrigate band 9 can closely be connected on the transverse pipe again.
