Abstract

The utility model discloses a local thickened plastic hose different from a common plastic hose, characterized in that: the hose wall thickness on different parts of the local thickened plastic hose is different; on the special part, one or more than one local thickened strip body (2) is arranged on the inner side surface or the outer side surface of the hose wall circle or the inner, outer side surfaces of the hose wall circle in a certain width (width adaptive with an insertion type pipe), the long edge of the lock thickened strip body is parallel to the vertical axis direction of the local thickened plastic hose, thus the thickness and hardness of the strip body corresponds with the requirement of the insertion type pipe; the envelope line on the edge of the cross section of the thickened strip body may by in arbitrary shape. The local thickened plastic hose has the following main advantages: the flexibility of the common plastic hose is kept, the plastic hose is easily produced and mounted; the using cost is greatly reduced and the local thickened plastic hose is widely applied in the agriculture, forestry water-saving irrigation technical fields. The manufacture material of the local thickened plastic hose is a plastic type material, such as PE, PVC.

Description

Local thickening plastic flexible pipe

Technical field

The utility model relates to farming, woods, meadow and 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 the utility model provides a kind of structure and is 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 utility model 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 one or more 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 one or more 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

The utility model has the advantages that: 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.
