Abstract

The invention discloses a locally thickened plastic flexible pipe different from an ordinary plastic flexible pipe. The locally thickened plastic flexible pipe is characterized in that thicknesses of the pipe wall at all parts are different; one or more locally thickened long bars (2) are arranged in specific parts, the inner side face or the outer side face of pipe wall circumference or the inner side face and the outer side face at the same part of the pipe wall circumference and within certain width (a width suitable for a plug-in type pipe fitting), the long edges of the long bars are parallel to the longitudinal axis of the locally thickened plastic flexible pipe; alternatively, more than one row (including one row) of discontinuously thickened blocks (13) is arranged, the thickness and hardness of the discontinuously thickened blocks (13) conform to the requirements of the plug-in type pipe fitting, and the cross section of the thickened long bars or the edge envelope curve (14) of the cross section of the locally thickened blocks can be of any shape. The locally thickened plastic flexible pipe has the main advantages of maintaining the flexibility of the ordinary plastic flexible pipe, being easy in production and installation, greatly reducing the use cost, and being capable of being widely applied to the field of water-saving irrigation in agriculture, forestry and the like. The locally thickened plastic flexible pipe is made of plastic materials, such as PE (Polyethylene) or PVC (Poly Vinyl Chloride).

Description

Local thickening plastic flexible pipe
Technical field
The present invention relates to farming, woods, meadow irrigates with final stage conduit pipe (directly connecing drip irrigation zone or other irrigators on it); It relates to being connected of final stage conduit pipe structure and irrigator and final stage conduit pipe.
Background technique
Farming, forestry water-saving irrigation technique; Can be divided three classes: water-saving irrigation on the ground (for example sprinkling irrigation), face of land water-saving irrigation (for example drip irrigation, infiltrating irrigation; Perhaps so the drip irrigation under the film, infiltrating irrigation), and underground water-saving irrigation (for example the sub-irrigation band is irrigated, the infiltrating irrigation head is irrigated, the irrigation of infiltrating irrigation rope, the irrigation of infiltrating irrigation jar etc.).
Its final stage conduit pipes (directly connecing drip irrigation zone or other irrigators on it) such as the drip irrigation on the face of land, filtration irrigation device have the branch of plastic flexible pipe, plastic rigid pipe; Different thereupon with the pipe fitting of its corresponding connection irrigator; Can not exchange use; The pipe fitting that connects common plastics flexible pipe and irrigator adopts nut to screw usually, and pipe fitting is connected with the common plastics flexible pipe, connects irrigator thereafter; The pipe fitting that connects plastic rigid pipe and irrigator adopts plug-in type usually, makes pipe fitting be connected (the plug-in type pipe fitting can not be used for plastic flexible pipe, mainly is that difficulty is fixed, sealed to the plug-in type pipe fitting because the plastic flexible pipe tube wall is thin, and pipe is soft) with plastic rigid pipe; Its plug-in type pipe fitting advantage is simple in structure, and is easy to use, cheap; Common plastics flexible pipe tube wall is thin, in light weight, and cost is low, is convenient to folding and unfolding, preservation, makes things convenient for the farmland mechanical work; Being popular, is the main direction of Future Development, but the fastening pipe fitting complex structure of the nut of its connection; Required precision is high, and trouble is installed, and cost is about 3 times of plug-in type pipe fitting.
Summary of the invention
The purpose of this invention is to provide a kind of structure and be different from common plastic flexible pipe; Be referred to as local thickening plastic flexible pipe; It has promptly kept the ductility of common plastics flexible pipe; Cost only has increase (cooperate the plug-in type pipe fitting, user cost has decline by a relatively large margin) slightly, can be connected with the plug-in type pipe fitting is convenient again simultaneously; Each position of pipe thickness of local thickening plastic flexible pipe is different.
For reaching this purpose, only need ask the position that is connected with the plug-in type pipe fitting on the common plastics flexible pipe to have certain thickness, hardness to get final product, and unnecessary whole plastic pipe increase thickness, hardness.
The method that the present invention adopts is: when producing part thickening plastic flexible pipe; On the inner side surface of tube wall circumference or on the outer side surface or at the tube wall circumference with the position on the inside and outside side, in certain width (width that adapts with the plug-in type pipe fitting); Suitably increase pipe thickness; Make the thickening position form thickening elongate body (2), [be equivalent on common plastics hose inner wall face or on the outer wall or on inside and outside wall, set up local thickening elongate body (2)] with the position; Its long limit is parallel with local thickening plastic flexible pipe y direction, and the thickness of its elongate body, hardness meet the connection request of plug-in type pipe fitting; This thickening position is used for punching and connects the plug-in type pipe fitting, connects drip irrigation zone or other irrigators thereafter; For preventing in install operation process; The fold damage takes place in the varied in thickness place, two side, long limit of the elongate body that adds thickness; Preferably the tangent line with the node (5) of tube wall circumference intersection is not vertical for its thickening elongate body cross-sectional edge envelope (3), and straight up and down promptly (can be straight up and down), and adopt slope shape or arc shape; The position, both sides, long limit that promptly thickeies elongate body thickeies gradually; Make it mild transition, also can be vertical with the tangent line of point (5) on the tube wall circumference, the middle part of its thickening elongate body cross-sectional edge envelope (3) can be cambered surface or plane; Thickening elongate body cross-sectional edge envelope can be an arbitrary shape.
The manufactured materials of this part thickening flexible pipe is a plastic materials, can be PE or PVC material or other plastic materialss.
Description of drawings
Advantage of the present invention is: it is easy to produce, and only need transform the mold head of original production flexible pipe equipment a little to get final product; Easy to use, can use the plug-in type pipe fitting to connect, be easy to install; Use the plug-in type pipe fitting, user cost declines to a great extent; The superiority that has kept flexible pipe; Be easy to large size and promote the use of, can be widely used in water saving irrigation fields such as agricultural, forestry.
