Abstract

The utility model discloses a PVC high pressure injection spray pipe, characterized by: PVC plastic tubing heart center is provided with two end difference fixedly connected with water pipe head and atomising heads of a root circle metal wire, PVC plastic tubing, the atomising head pyramis forms the cone angle of 60 -120 degree. According to the spraying needs of difference, can adopt different atomising heads. PVC plastic tubing heart center is provided with a root circle metal wire, can roll over in the time of need buckling in the use and carry out the operation to optional orientation.

Description

A kind of PVC high-pressure fog pipe

Technical field

The utility model relates to the water spray or sprayer unit that use in people's agricultural production, specifically a kind of novel high pressure P VC injection spray pipe.

Background technology

From ancient times to the present, the water spray that people use in agricultural is raw or sprayer unit just have various, but, existing water spray or its function of sprayer unit can only 360 degree rotate and flexible work or adopt artificial trombone slide etc. up and down, and target of perfectly sprinkling irrigation etc. cannot be reached in many cases.Therefore overcome existing Problems existing, propose solve scheme be when business urgently.

Utility model content

The utility model provides a kind of PVC high-pressure fog pipe, is realized by following scheme:

It is characterized in that, PVC plastic pipe heart center is provided with a round wire, and two ends of PVC plastic pipe are fixedly connected with water pipe head and fog-spray nozzle respectively; Fog-spray nozzle tapering forms the coning angle of 60-120 degree.

In certain embodiments, the cross section, tapering of wherein said fog-spray nozzle is square.

In certain embodiments, the cross section, tapering of wherein said fog-spray nozzle is arc-shaped.

In certain embodiments, the cross section, tapering of wherein said fog-spray nozzle is circular.

The beneficial effects of the utility model: according to different spraying needs, different fog-spray nozzles can be adopted.PVC plastic pipe heart center is provided with a round wire, in use needs can be folded to arbitrary direction during bending and carries out operation.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model PVC injection spray pipe;

Fig. 2 is the sectional view of spray nozzle of the present utility model; Wherein, the cone angle alpha of the ozzle 4 of Fig. 2 a is 60 degree, adopts 90 degree in the ozzle 4 of Fig. 2 b, adopts 120 degree in the ozzle 4 of Fig. 2 c, and adopt the coning angle of 30 degree in the ozzle 4 of Fig. 2 d, the ozzle of Fig. 2 e ~ g all has the tapering of cross section arc-shaped.

Detailed description of the invention

Shown in Fig. 1, PVC plastic pipe 1 heart center is provided with a round wire 2, and two ends of PVC plastic pipe 1 are fixedly connected with water pipe head 3 and fog-spray nozzle 4 respectively; Two terminations of the round wire 2 at PVC plastic pipe 1 heart center are also connected with water pipe head 3 and fog-spray nozzle 4 inner chamber respectively and coordinate.

Fig. 2 a, Fig. 2 b, Fig. 2 c and Fig. 2 d change the cone angle alpha in tapering 41.The cone angle alpha of the ozzle 4 of Fig. 2 a is 60 degree, adopts 90 degree, adopts 120 degree in the ozzle 4 of Fig. 2 c, the coning angle of employing 30 degree in the ozzle 4 of Fig. 2 d in the ozzle 4 of Fig. 2 b.The occasion that cone angle alpha in tapering 41 is narrower than 30 degree, spray pattern is wide, but the concentration of central part uprises, and concentration gradient becomes large, so the contour part of spray pattern has and is similar to straight line, becomes mild parabolical tendency.In addition, the occasion that the cone angle alpha in tapering 41 is wider than 120 degree, spray pattern narrows, and the concentration of central part is high, and concentration gradient becomes large, so the contour part of spray pattern has and is similar to straight line, becomes mild parabolical tendency.

On the other hand, the ozzle of Fig. 2 e ~ g all has the tapering (or shoulder) 17 of cross section arc-shaped.Tapering 41 in the ozzle 4 of Fig. 2 e has the cross section of semiellipse shape, and the ozzle 4 of Fig. 2 f is along with becoming its curvature of ozzle 4 change of Fig. 2 g greatly.In addition, in the ozzle 4 of Fig. 2 g, radius of curvature R is 1.5mm.

In certain embodiments, the cross section, tapering of wherein said fog-spray nozzle is square, arc-shaped or circle.

Claims
